A. Justification
A.1 Circumstances Making the Collection of Information Necessary
Legislative Mandate
The President’s Task Force on Health Risks and Safety Risks to Children recommended in 1999 that a large study to define the actual risks associated with broad environmental exposures is the critical first step in addressing the potential risk factors that may affect the health and development of children in the United States (US). Following the recommendation of the task force, Congress passed the Children’s Health Act of 2000 (Public Law 106-310) which authorized the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) to conduct a national longitudinal study of environmental influences on children’s health and development. These environmental influences include physical, chemical, biological, and psychosocial aspects.
The Children’s Health Act of 2000 (Sec. 1004) states that the Director of the NICHD shall establish a consortium of representatives from appropriate Federal agencies to: “Plan, develop, and implement a prospective cohort study, from birth to adulthood, to evaluate the effects of both chronic and intermittent exposures on child health and human development.”
“Investigate basic mechanisms of development disorders and environmental factors, both risk and protective, that influence health and development that influence health and developmental processes. “
This national longitudinal study, termed the National Children’s Study [NCS], is required by law to include three research imperatives justifying the collection of information:
“Incorporate behavioral, emotional, education, and contextual consequences to enable a complete assessment of the physical, chemical, biological and psychosocial environmental influences on children’s well-being.”
“Gather data on environmental influences and outcomes on diverse population for children, which may include the consideration of prenatal exposures.”
“Consider health disparities among children which may include the consideration of prenatal exposures.”
Purpose of Vanguard (Pilot) Study
The NCS Vanguard (Pilot) Study (OMB #0925-0593) was approved by the Office of Information and Regulatory Affairs within the Office of Management and Budget with an expiration date of 7/31/2013. The purpose of the Vanguard (Pilot) Study is to assess the feasibility, acceptability, and cost of the recruitment strategy, study logistics and operations, and study visit assessments that will be used in the second component, the NCS Main Study. “Feasibility” assessment refers to technical performance and reliability. “Acceptability” refers to the impact on the study participants and overall study infrastructure. “Cost” refers to the level of effort, personnel, resources, and money involved in a study development and implementation. The NCS Main Study, currently in the concept phase, will run in parallel with the NCS Vanguard (Pilot) Study. Additional substudies and formative research projects will inform future NCS design and activities. Currently, the design of the Main Study is being informed by the experience obtained in the Initial Vanguard Study, combined with data from the Alternate Recruitment Substudy.
Purpose of this Submission
The National Children’s Study is an integrated system of activities that includes a Vanguard (Pilot) Study for operations and methods development, and an NCS Main Study to collect data on exposure and response. The Vanguard (Pilot) Study, which includes the Initial Vanguard Study, the Alternate Recruitment Substudy (Phases 1 and 2), and the Provider-Based Sampling Feasibility Study (proposed in this information collection request), is currently underway. The Main Study is expected to follow within the next year. This request for revision includes (1) the addition of a Provider-Based Sampling Feasibility Study, and (2) supplemental measures for the Alternate Recruitment Substudy involving revised study visit assessments, physical measurements, and additional biospecimen collections. These information collections, revisions of instruments, physical measure implementation, and biospecimen collections will evaluate the feasibility, acceptability, and cost of study design elements to inform the Main Study.
History of the NCS Vanguard (Pilot) Study Data Collection Activities
NCS Initial Vanguard Study
In 2009, the NCS began data collection in the Initial Vanguard Study at 7 locations, within Primary Sampling Units (PSUs, or counties). The Initial Vanguard Study protocol was designed to enroll approximately 1,750 pregnant women residing within selected geographic segments of the Primary Sampling Units termed Secondary Sampling Units at the seven study locations after 12 months of data collection using a household enumeration and screening strategy to identify eligible women for recruitment. As of May 2010, however, approximately 900 pregnant women had been enrolled, signaling that the initial approach of conducting a household survey would take much longer than intended, resulting in increased costs and delays in implementing the critical data collection for the NCS. In total, approximately 1,100 participant families were enrolled during the Initial Vanguard Study phase of the Vanguard (Pilot) Study.
Alternate Recruitment Substudy Phases 1 and 2
Based on data analysis from the Initial Vanguard Study, the NCS designed an approach termed the Alternate Recruitment Substudy (ARS) to systematically explore three recruitment strategies based on how members of the public were informed of the Study: 1) Provider-Based Recruitment; 2) Enhanced Household-Based Recruitment; and, 3) Two-Tiered “High-Intensity/Low-Intensity” Recruitment. The guiding research goal for the ARS was to characterize recruitment strategies that could be used to identify, recruit, and enroll eligible participants into a population-based cohort study. A secondary goal of the ARS was to systematically determine the effect of how initial contact between the public and the Study influenced recruitment. The comparison was between initial contact with a trusted individual (health care provider – Provider-Based Recruitment), with a stranger (NCS field worker – Enhanced Household-Based Recruitment), and with direct outreach through media and staged events (Two-Tiered “High-Intensity/Low-Intensity” Recruitment). Each of these three recruitment strategies was implemented in 10 locations for a total of 30 locations. Coupled with the seven study locations collecting data in the Initial Vanguard Study, information collection occurred at a total of 37 locations in the Vanguard (Pilot) Study.
Phase 1 of the ARS involved the administration of questionnaires at each study visit and began in July 2010 when the NCS obtained clearance from OIRA. Phase 2 of the ARS added a questionnaire targeted to fathers and introduced biospecimen and environmental sample collections. Twenty-two of 37 study locations began biospecimen and environmental sample collection during the fourth quarter of 2011.
From July 2012 through December 2012, data collection at the seven Initial Vanguard locations will be conducted by a single contract research organization. This transition coincides with the expiration of the seven Study Center contracts and the gap until the award of new contracts for administration of the Vanguard (Pilot) Study. New contract awards are expected in September 2012 with data collection activities beginning in January 2013. For a period of 6 months, approximately 1,100 children will be followed via telephone or other remote data collection modes. The NCS intends to re-consent these participant families. While the number of Study visits varies by the age of the child, on average, each enrolled participant will be administered a single questionnaire by telephone. The questionnaire will be the age-appropriate visit, as approved by OIRA. All study locations involved in the NCS Vanguard Study will continue to follow Study participants enrolled at their study locations for the next two decades.

Table A.1.1 outlines the history of the NCS Vanguard (Pilot) and Main Study data collection activities between 2008 and the present. The table briefly describes OIRA clearance dates, number of study locations at each phase, primary data collection activities during each phase, and data collection activities proposed in this information collection request. Phase 2 expanded data collection activities (including sample and physical measures collections) will be performed by the following study locations:
Provider-Based Recruitment study locations (ARS): Durham County, NC; Hinds County, MS; Lamar County, TX; Schuylkill County PA; Wayne County, MI
Enhanced Household-Based Recruitment study locations (ARS): Baker County, FL, Cumberland County, ME; Cuyahoga County, OH; Polk County, IA; St. Louis, MO
Two-Tier High/Low Intensity Recruitment study locations (ARS): Baldwin County, GA; Cache County, UT; Davidson County, TN; Douglas County, CO; Westmoreland County, PA
The fifteen study locations conducting Phase 2 expanded data collection were selected based on several criteria including readiness to collect environmental samples and biospecimens, physical measures, and the father interview, quality of prior data submissions, and number of participants.
Preliminary Results from the ARS
The preliminary results indicate that each recruitment strategy differs in efficiency (the number of women contacted compared to the number enrolled) and that each strategy has different biases. Overall, the Provider-Based Recruitment strategy was the most efficient with about 2 women contacted for each woman enrolled and the highest proportion of women who were enrolled during pregnancy. Details can be seen in Table A.2.1.

For Provider-Based Recruitment, about 175,000 addresses were pre-screened using an Address Lookup Tool to identify the 3,350 women potentially eligible based on residence in a Secondary Sampling Unit (SSU, or segments within a PSU) for the Provider-Based Recruitment strategy. The Address Lookup Tool only provides an approximate indication of whether a woman resides within an NCS SSU. About 66% of the women contacted for the Pregnancy Screener completed the pregnancy screen. The 34% difference between women contacted and women who completed the Pregnancy Screener was primarily due to additional women who were deemed ineligible for participation based on having an address outside an SSU.
Given that the ARS aimed to characterize recruitment strategies and its components that are effective in identifying, recruiting, and enrolling eligible participants into a population-based cohort study, and to determine the effect of how initial contact between the public and the Study influenced recruitment, the NCS used the preliminary data to conclude that sufficient data were collected to be analyzed to design next steps. Consequently, the NCS halted ARS recruitment (Provider-Based Recruitment, Enhanced Household-Based Recruitment, Two-Tier Recruitment) in February 2012.
NOTE: New Data Collections and Updates to the National Children’s Study (NICHD)
Provider-Based Sampling Feasibility Study for the Vanguard (Pilot) Study
The NCS Program Office began in April 2011 a series of consultations including open public meetings to solicit input on the design of the Main Study using recruitment by health care providers. In the spring of 2012 the NCS Program Office integrated the advice and input to develop a proposal for a recruitment model that is based upon a layered cohort approach. The initial sampling frame would be based on geographic areas. Following selection of geographic areas using a probability based approach, hospitals that provided delivery services and birthing centers would be enumerated and listed within each selected area. From that list, again using a probability based approach, hospitals and birthing centers would be selected to recruit a birth cohort. In addition, prenatal care providers associated with the selected facilities would be listed to enroll a second cohort of pregnant women. The selection of prenatal providers and pregnant women would also use a probability based approach.
To better understand the potential efficiencies and processes of a prenatal care provider-based model and relate it to the proposed Main Study approach, the NCS proposes a new approach to eliminate the recruitment limitation of requiring participants to reside within small geographic SSUs, and instead, base the geographic eligibility on residing within the larger PSU. In addition, we propose using either the birth visit or the initial prenatal visit as a screening tool to allow for a uniform probability of selection of participants, and to target a decrease in the gestational age at recruitment for pregnant women when compared to the earlier NCS Vanguard Study Provider-Based Recruitment arm. Therefore, the NCS would like to improve upon the Provider-Based Recruitment strategy by screening potential participants by provider location, age eligibility, and residence in the sampled Primary Sampling Unit (PSU), confirmed pregnancy, and either scheduled with a prenatal care provider for an initial prenatal visit or present at a selected facility for birth (Provider-Based Sampling). In this pilot, a Provider can be an individual (physician, midwife, nurse practitioner, or physician assistant), an office-based practice or a facility, including hospitals and birthing centers. We intend to assign office or clinic based practices that will enroll pregnant women in a prenatal cohort and hospitals and birthing centers that will enroll women during the perinatal period to separate strata.
The NCS proposes to systematically assess the feasibility, acceptability, and cost of Provider-Based Sampling. In this strategy, a list of prenatal care providers who serve women residing in a specific PSU will be compiled using a variety of data sources, such as birth records and licensing information. In some cases, using the Provider-Based Sampling Frame Questionnaire, identified providers will supply practice characteristics and the measure of size (MOS) for their practice location(s). This information (practice characteristics and MOS) will be used in the systematic selection of providers from the larger list frame. Selected provider locations will be invited to serve as recruitment sites for the enrollment of pregnant women in the NCS. Procedures for recruiting pregnant women will be the same as those procedures that were fielded in the Provider-Based Recruitment (PBR) arm of the Vanguard Study Alternate Recruitment (ARS) Substudy. Data collected during the participant study visits will be the same as those approved by OIRA and implemented in the ARS, excluding preconception activities and Phase 2 expanded collection activities (biospecimen and environmental sample collection, physical measures collection, and the Father Interview, see Table A.1.1). In the Vanguard (Pilot) Study Request for Renewal in 2013, we will request approval for sample collection, physical measures, and the Father Interview for the PBS cohort.
Developing the Sampling Frame
The NCS proposes to determine if adopting a provider-based sampling approach is feasible, and if such an approach could provide decreased cost, increased acceptability, and overall a more flexible model for NCS recruitment. Three additional study locations have been selected to pilot this approach in their respective Study Locations (PSUs). Based on information from the ARS, the NCS believes that three PSUs is the appropriate sample size needed to determine if the provider-based sampling approach is feasible and efficient. Use of three PSUs fits within NCS’s budget and emphasis on improving efficiency in field operations, while imposing the minimum public burden to achieve the purposes of the feasibility study.
The following are examples of data sources that will be used to compile lists of prenatal providers:
Publicly-available datasets that list delivery hospitals, medical insurance providers, public clinics, academic medical institutions and professional organizations.
Birth records that include named “Birth Attendant” and “Birth Attendant Address,” which may allow for a compilation of area prenatal care providers.
Publicly-available datasets from Web sites, phone directories, local medical society directories, to confirm provider practice location status (for example, has the provider retired, moved, or altered the focus of the practice?).
Determining Measure of Size (MOS) and Selecting Provider Locations
We will determine MOS for each provider location using any or all of the following methods:
An initial postcard or letter mailing to each provider location, introducing the Study, alerting them to the fact than an NCS staff member will be contacting them, and providing NCS contact information.
Telephone calls to provider locations to further introduce the Study, explain the Provider-Based Sampling Frame Questionnaire, and identify the provider’s preferred mode of questionnaire administration. Data collection modes may include telephone administration by field staff, in-person administration by field staff, a mailed self-administered questionnaire (SAQ), or a combination of these. During this process, Study Locations will begin building a relationship with each provider location.
Based on identified provider preferences, Study Locations will conduct in-person or telephone interviews with office managers, administrators, or prenatal care providers at each location to complete the Provider-Based Sampling Frame Questionnaire for each location. As needed, the Provider-Based Sampling Frame Questionnaire may be sent directly to provider practice locations for completion as a self-administered questionnaire (SAQ). Study location outreach staff to monitor receipt of questionnaires, and follow-up as necessary with the lead person of the provider location until all questionnaires are collected.
MOS (the estimated number of first prenatal care visits from women who reside in the sample PSU) for each provider location will be computed based on data obtained from the Provider-Based Sampling Frame Questionnaire, geocoding, and other available data sources.
Once the sampling frame is constructed and following probability statistical parameters (see Supporting Statement B. 1), we will select a subset of provider locations to invite to serve as recruitment locations for Provider-Based Sampling effort.
Recruiting Study Participants in the PBS
Recruitment of Study participants at the selected provider locations will follow the protocol and procedures developed for the Provider-Based Recruitment (PBR) arm of the ARS, as previously approved by OIRA. However, participants will not participate in preconception activities, and this new approach will not require screening of large numbers of addresses, as we would no longer need to identify women living in selected SSUs. Instead, potential participants will be screened only on age eligibility, residence in the sampled PSU (county), confirmed pregnancy, and appearance for an initial prenatal visit (Pregnancy Visit 1) using the Provider-Based Sampling Eligibility Screener. In some locations, medical records may be pre-screened to identify participants meeting these eligibility criteria. Post-enrollment, PBS participants will be administered the previously-approved Pregnancy Visit 1 instrument if appropriate and receive all subsequent Study Visits already in use in the ARS (excluding the Father Interview). Unlike earlier arms of the NCS Vanguard (Pilot) Study, PBS participants will not be enrolled prior to pregnancy and will not participate in preconception activities.
The recruitment goal for this feasibility study will be 250 births per PSU. Based on our experience from the Provider-Based Recruitment (PBR) strategy of the ARS, about 80% of identified eligible women agreed to enroll in the NCS. Assuming an 80% enrollment rate and an estimated attrition rate of 20% (from pregnancy loss and participant attrition through birth), we estimate that about 400 eligible women will need to be invited to participate in each PSU in order to achieve the desired number of 250 births per PSU in this feasibility study. Pilot testing Provider-Based Sampling will allow the NCS to understand the feasibility, acceptability, and cost of this recruitment approach, and will provide a comparison of response and retention rates between Provider-Based Sampling (PBS) and Provider-Based Recruitment (PBR).and to quantitatively establish the ability to recruit women more efficiently and economically using this approach.
Prior to posting a 60-day Federal Register notice for the Main Study, we will acquire at least 4 months of recruitment data using the Provider-Based Sampling Frame approach described above to meet the target of inviting 1,200 pregnant women across the three Study Locations to participate in the Study, enrolling 960 pregnant women at the first prenatal care visit. We estimate an 80% participant retention rate for pregnant women from the first prenatal care visit to the birth of the child, and assuming for this calculation that all of the enrolled women were enrolled in the prenatal stratum, resulting in approximately 750 births during the entire feasibility study. Note that the actual number of births is dependent upon the number of provider locations that agree to serve as recruitment locations for the PBS.
Through our experience in the Vanguard (Pilot) Study, we learned that ‘steady state’ in terms of stabilization of recruitment and early retention efforts was achieved in 9 months or less following initiation. Prior to posting a 30-day Federal Register notice for an OMB submission related to the Main Study, we would have 6-8 months of data on recruitment and retention of participants through birth to assess success of this approach. These data, in combination with what is still being tested in the Vanguard (Pilot) Study, will add to our broader understanding of the drivers of early participant retention.
Supplemental Information and Biospecimen and Physical Measures Collections for the Continuing ARS
This ICR revision also covers the following activities associated with the NCS Vanguard Study:
Extend data collection for the children who have been recruited into the NCS Vanguard Study up to 30 months of age of the child by introducing the Core Questionnaire at the 30- Month Interview
Supplemental data collection designed to update and validate existing data collection include the introduction of validation questions for the 18-, 24-, and 30-Month Interviews, a revised Father Interview, and a new Nonrespondent Questionnaire.
Other previously-approved study assessment questionnaires have been modified based on feedback from field workers and are included in this information collection
Finally, physical measures that were initially approved for the Initial Vanguard Study (first seven study locations) and envisioned to eventually be added for the participants recruited through the Alternate Recruitment Substudy (30 study locations, excluding Two-Tier Low-Intensity participants) will be initiated at this point in time. Specifically, breast milk collection will be re-introduced at 1 and 3 months, and collection of infant urine, saliva, and blood will begin at the 6- and/or 12-month visits. At this time, biospecimen, environmental samples, physical measures, and the Father Interview will not be collected at the Provider-Based Sampling study locations. Further detail on these changes can be found in A.2 (Purpose and Use of the Information Collection) and B.2 (Procedures for the Collection of Information.
A.2 Purpose and Use of the Information Collection
The Initial Vanguard Study and the ARS have yielded valuable data and field experience regarding the robustness, participant and study infrastructure burden, and cost of piloted study visit measures. As the Study continues, the NCS Program Office has identified additional measures for piloting before consideration for implementation in the NCS Main Study. Among the piloted items is the Provider-Based Sampling Feasibility Study. The main goals of the Provider-Based Sampling Feasibility Study are:
To learn how to develop a list frame of providers. The specific details on the sources used for the lists of providers and how each Study Center involved in Provider-Based Sampling compiles this information will be used to provide information on the list frame development process.
To examine the efficiencies of recruiting pregnant women, including how early in pregnancy they can be recruited. This will help the NCS calibrate expectations for Main Study recruitment activities and the likelihood of collecting data on early prenatal exposures.
To generate data on cost.
To generate data on costs associated with developing sampling frames of providers, gaining cooperation of providers, identification and enrollment of participants, and implementation of Study Visits.
To establish participation rates of providers, including willingness to provide information requested by the Provider-Based Sampling Frame Questionnaire, and, if selected, to serve as a NCS recruitment location.
To compare the efficiency, demographics, quantity and quality of environmental exposure information and retention of populations of women perinatally with women recruited early in pregnancy.
The purpose of the overall proposed data collection is to obtain operational and performance data on processes, new measures, and study visit activities. In combination, the substudies encompassed by the Vanguard (Pilot) phase will be used to inform the design of the NCS Main Study. The Main Study will provide the data needed to evaluate exposure-response relationships.
Provider-Based Sampling Feasibility Study for the Vanguard (Pilot) Study
Provider-Based Sampling Frame Questionnaire: We will ask selected providers within the PSU to complete a brief questionnaire about their practice and their patient demographics. We will use information from this questionnaire to further develop the sampling frame and, in particular, will request the number of births attended by each practice or occurring at each facility as a measure of size (MOS) and information to be used in forming strata (e.g. geographic location of the study office, hospital or birthing center or demographic characteristics of the patient population).
Provider-Based Sampling Eligibility Screener: We will use this instrument to determine if a woman is eligible for participation for Provider-Based Sampling. Variables include the age of the potential participant, pregnancy status, county of residence, and whether or not the indexed visit is the first prenatal care visit. The instrument also captures demographic information to allow characterization of the population approached and comparisons of eligible and ineligible respondents.
Supplemental Measures for the Vanguard (Pilot) Study involving Study Visit Assessments Using a Core Questionnaire
We propose pilot use of a Core Questionnaire containing important variables designed to collect core data at every study visit from the time that the enrolled child is 6 months of age to the time the child is 5 years of age. Use of this instrument would allow consistent collection of housing characteristics and composition, neighborhood features, childcare arrangements, and healthcare utilization and access. Additional content of the Core Questionnaire includes sleeping patterns, medication assessment, and parental occupation and income. Along with this questionnaire, the respondent would complete age -or special topic modules (see 30-Month Interview Module). We propose piloting the Core Questionnaire at the 30-Month Interview. Results of this pilot will inform whether to incorporate the Core Questionnaire in existing and future visits.
Infant Race and Ethnicity: We ask to include a mother-reported measure of race/ethnicity for infants enrolled in the NCS Vanguard Study. The measures (variable BC007B/ETHNICITY; BC007C/RACE) are the same as that approved by OIRA (7/22/2010) to measure adult race/ethnicity. These would be included in the Birth Interview and the Birth Instrument for Two-Tier Low-Intensity. This information is necessary to comply with IRB reporting requirements at the time of continuing review.
30-Month Interview Module: We propose piloting the use of an age-specific module along with the Core Questionnaire at the 30-Month Interview. Constructs to be collected for this interview were developed with input from the study locations who offered expertise.
After collection of data from the 30-Month Interview, the NCS will analyze the feasibility, acceptability, and cost of this visit as a whole, as well as specific measures of mental health and neurodevelopmental outcomes. The age-specific modules include questions that measure constructs particularly relevant at that age. Some of these constructs are measured with a series of questions (such as parenting practices at a given age) while others are measured with previously validated assessment tools. Two instruments that have been chosen to obtain information about key dimensions in children’s earliest development at the 30-month data collection are the Brief Infant/Toddler Social and Emotional Assessment (BITSEA), and the Infant-Toddler Sensory Profile. Both measures are completed by the parent/caregiver about the child. These measures were selected because they each uniquely obtain information about discrete aspects of child behavior, they are psychometrically sound, and they can be completed by the parent/caregiver on the basis of their observations about the child’s typical behaviors. In addition, a third measure, the Brief Symptom Inventory-Revised (BSI-R), was chosen to obtain information about parent/caregiver mental health, which may contribute to, may moderate, or may alleviate children’s problem behaviors (such as parental depression) that have been shown to negatively affect children’s development. The BSI-R is completed by the parent/caregiver about his/her own mental health. A description of each of the selected standard assessments is provided below.
There are two learning objectives associated with administration of the BITSEA, the Infant Toddler Sensory Profile and the Brief Symptom Inventory. The first objective is to obtain information about feasibility, acceptability and cost of administration of each of these tools within the context of the NCS. This will be assessed by looking at unit response rates, item response rates, and participant reactions to the various assessments (captured in interviewer comments and debriefings). The second objective is to determine whether responses obtained are consistent with what would be expected from the literature and in comparison with publisher norms.
Brief Infant/Toddler Social and Emotional Assessment (BITSEA) - The BITSEA is a screening instrument designed to be completed by the parent/caregiver to identify children at-risk or currently experiencing social-emotional or behavioral problems, or delays in social-emotional competence. It assesses children’s social-emotional competence, problem behaviors such as externalizing and internalizing behaviors, and behavioral and emotional dysregulation (such as sleep disturbances, eating difficulties, and negative emotionality). Social-emotional competence evolves over time and can be measured with the BITSEA beginning at 12 months. The NCS already includes the BITSEA as part of the 12-Month Interview. With this ICR, we propose including the BITSEA in the 30-Month Visit as well, to establish a trajectory of development for this construct. It is estimated that it will take the parent/caregiver approximately 10 minutes to complete this questionnaire.
Infant Toddler Sensory Profile - The Infant/Toddler Sensory Profile is completed by the parent/caregiver measuring children’s responses to sensory events in daily life. Young children’s sensory processing can reveal sensitivities and difficulties that have been associated with the later diagnosis of ADHD and other learning disabilities. By 30 months of age, sensory responses may be consolidating into patterns of difficulties that have enduring effects on development, particularly cognitive development. The Infant/Toddler Sensory Profile is estimated to take under 15 minutes for the parent/caregiver to complete.
Brief Symptom Inventory-Revised - The Brief Symptom Inventory-Revised (BSI-R) is a 53-item inventory that covers nine symptom dimensions about the respondent: Somatization, Obsession-Compulsion, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic anxiety, Paranoid ideation and Psychoticism; and three global indices of distress: Global Severity Index, Positive Symptom Distress Index, and Positive Symptom Total. We are interested in testing the BSI as a measure of parental mental health that could be administered during pregnancy and again during the child’s early years. The BSI-R was chosen to be included at the 30-month data collection because parent/caregiver mental health functioning is an important contributor to young children’s development and may mediate or exacerbate any difficulties that children may be experiencing. It is estimated that the BSI-R will require about 10 minutes for the parent/caregiver to complete.
Validation Questions for 18, 24 and 30 month: The administration of a validation questionnaire following a study visit is a well-established field practice designed to monitor interviewer performance and identify occurrences of data falsification. Questions have been added to the validation questionnaire that currently covers prenatal visits through 12 months. We propose addition of brief telephone-based questions that would be fielded to a random sample of each interviewer’s cases after completion of the 18-Month, 24-Month, and 30-Month Interviews. Each set of questions would confirm the administration of a study visit, include one or two questions asked in the original instrument that should yield a consistent answer from participants, and allow participants the opportunity to provide additional feedback on the interviewer and the Study.
Nonrespondent Questionnaire: It is critical for the NCS to understand the characteristics and attitudes of enrolled women, those who withdraw, as well as those who choose not to enroll. This information may be used to revise our approaches to recruitment and will help the Study frame other systematic analyses of nonresponse bias. The Nonrespondent Questionnaire is designed to be interviewer-administered in-person, by telephone, via web, or by mail, and will collect information on why a participant chose to not enroll in or to withdraw from the NCS. The instrument will assess the impact of family and health care providers and key study characteristics (for example, biospecimen collection or sensitive questions) on the decision-making process. The instrument asks generally about the collection of biospecimens and allows the respondent an opportunity to provide unstructured comments and feedback to the NCS. Originally, this instrument was conceived to evaluate nonresponse across the ARS sites, but this purpose will be adjusted due to programmatic changes associated with Provider-Based Sampling. We will plan to revise this questionnaire after pilot data is collected (within the next year) to understand the impact of the Regional Operations Centers (for more information on Regional Operations Centers, please refer to A.15) and other program changes, including the addition of supplementary measures involving physical measurements and mother and child biospecimens collections.
Revised Father Interview: The results of consultations with experts in the field and an in-depth literature review have guided revisions to the Father Interview, which is administered before the child is born. The proposed revisions to the instrument now include measures of key social/personal resources and fathers’ capacity, desire and attitudes towards engaging with mothers and children. We would like to find out what impacts a father’s personal resources, social network, and involvement will have on the health of the expecting mother and the development of the child. We would also like to evaluate their attitudes towards being involved as a father, and what effects those attitudes have on the health of the expecting mother and the development of the child. In total, we hope to identify factors that predict positive father involvement in the overall protection of maternal and child health. Feasibility of the additional measures in the revised interview will be assessed by quantitatively analyzing the relationships of these additional measures with the existing measures.
Revised 24-Month Interview: The 24-Month Interview is revised to include specific questions for parents about the social, behavioral, and neurological development of their child. These questions, in the form of a validated screening tool known as M-CHATTM, are geared specifically to identify characteristics of autism and autism-spectrum disorders. Although the instrument is under copyright, the instrument is free for use in research studies and can be downloaded from the Internet. The NCS intends to follow the M-CHAT instructions for use (https://www.firstsigns.org/downloads/m-chat.PDF). The proposed revisions increase the interview length from 30 to 35 minutes per respondent.
Tracing Questions Module
The NCS is developing a modular approach to conducting study visits. Tracing questions were removed from all study visits, and a tracing module was developed for administration at all study visits for all recruitment methods.
Administration of 3-, 9-, 18-, and 24-Month Interviews to Two-Tier Low-Intensity Participants: In July 2010, the NCS was approved to administer the Low-Intensity Questionnaire (Child-Focus) a total of four times between birth and 24 months of age of the child. Currently, data collections with child-specific questions for Low-Intensity participants are not occurring after birth because development of a specific instrument for Low-Intensity participants is still underway. Administration of the 3-, 9-, 18-, and 24-month interviews enables the NCS to ask child-focus questions of Low-Intensity participants. In addition to the 3-, 9,-, 18-, and 24-month interviews, the 6- and 12-month interviews are administered to High-Intensity participants. This ICR also proposes the collection of child physical measurements and mother and infant biospecimen for High-Intensity participants. For more information, please refer to “Supplemental Measures for ARS involving Physical Measurements” and “Supplemental Collections for ARS involving Biospecimens” in A.2.
Modular Consent and Visit Information Sheet (VIS) Administration: The NCS has proposed the merging of the existing written VIS and short informational script into a single multi-mode introductory Visit Information Script (VISCR), for consistency purposes, that can be read to participants during both in-person study visits and for all visits conducted via telephone. A Sample Collection VIS will be read to participants for visits that include collection of biospecimens, environmental sample collections, and physical measure collections, excluding the Birth Visit and the 1- and 3-Month breast milk collections. The Sample Collection VIS describes the visit sample and measure collection activities planned, and after the data collector reviews the information with the participant, a hardcopy of the Sample Collection VIS is left with the participant for reference. Participants who choose not to provide consent for a particular biological or environmental sample at a given visit, will be read the VIS Sample Refusal Reconsideration Script at subsequent visits in which that type of sample may be collected. For more information, please refer to B.2.1.
Participant Verification Questionnaire: The Participant Verification Questionnaire intends to improve data quality by confirming that participant contact information is correct. The questionnaire will ensure that study visits are being conducted with the correct consented participants.
Supplemental Measures involving Physical Measurements and Biospecimens for ARS
Supplemental measures involving Physical Measurements and Mother and Infant Biospecimen collections were originally in the Initial Vanguard Study. As discussed below, only a small number of collections were completed. When the Alternate Recruitment Substudy was initially proposed, the research goals (mentioned in “Alternate Recruitment Substudy Phases 1 and 2” in A.1) focused on determining efficiencies among different recruitment approaches. For this reason, these supplemental measures were not proposed in information collection requests for Alternate Recruitment Substudy Phases 1 and 2. In this information collection request, the NCS proposes to pilot the collection of these supplemental measures in order to determine the feasibility and acceptability of collection by type, quality of resulting analytic data, rates of consent for collection, and the impact on retention.
Supplemental Measures for ARS involving Physical Measurements
Physical Measures: Physical measures are measures of child anthropometry (for example, height, weight, and head circumference) and blood pressure signaling growth and maturation. These measures, obtained at the 6, 12-, and 24-month interviews will provide information on the potential early childhood indicators in the development of obesity, diabetes, premature puberty and a host of other health outcomes and diseases. Physical measures were collected at the 6-Month Interview in the Initial Vanguard Study; however, with the ending of Initial Vanguard Study in September 2010, a relatively small number of collections were completed. Physical measures were planned but never implemented at 12 months. Additional collections are needed to determine the feasibility, acceptability and cost of collection. Feasibility and acceptability of physical measurement collection will be assessed by rates of successful completion of physical measurement by type, quality of resulting analytic data, rates of consent for measurement collection, and impact on retention.
Supplemental Collections for ARS involving Biospecimens
Mother and infant biospecimens (listed below) will be collected among a subset of study locations participating in the three ARS arms (Provider-Based Recruitment, Enhanced Household-Based Recruitment, Two-Tier Recruitment) that currently have OIRA clearance. Fifteen of 30 ARS locations were selected for re-introduction of sample collection based on individual site readiness and quality of individual site prior performance. These biospecimen collections will provide information about preparation and infrastructure needed to carry out these collections in the NCS Main Study. Biospecimen and environmental sample collection will not take place in Provider-Based Sampling, as these activities do not address the main goals of the Provider-Based Sampling Feasibility Study, which, as mentioned earlier in this section and for purposes of this information collection request, are related specifically to recruitment. We plan to propose biospecimen and environmental sample collection for participants enrolled via Provider-Based Sampling in a future information collection request.
Breast Milk Collection 1 and 3 months: Breast milk was collected in the Initial Vanguard Study; however with the ending of the Initial Vanguard Study in September 2010, a relatively small number of collections were completed. Additional breast milk collection is needed to determine the feasibility, acceptability and cost of this type of collection. Feasibility and acceptability of specimen collection will be assessed by rates of successful completion of specimen collection by type, quality of laboratory analytic result data, rates of consent for specimen collection, and impact on retention. For more information, please refer to A.16.
Infant Urine Collection at 6 and 12 months: Infant urine was collected at the 6-Month Interview in the Initial Vanguard Study, with the ending of the Initial Vanguard Study in September 2010, a relatively small number of collections were completed. Infant urine collection was planned but never implemented at 12 months. Additional urine collection is needed to determine the feasibility, acceptability and cost of this type of collection at these ages. Feasibility and acceptability of specimen collection will be assessed by rates of successful completion of specimen collection by type, quality of laboratory analytic result data, rates of consent for specimen collection, and impact on retention. For more information, please refer to A.16.
Infant Blood and Saliva Collection at 12 months: Infant blood and saliva collections were planned for the 12-Month Interview in the Initial Vanguard Study, but never implemented. Additional infant blood and saliva collections are needed to determine the feasibility, acceptability and cost of these types of specimen collections at this age. Feasibility and acceptability of specimen collection will be assessed by rates of successful completion of specimen collection by type, quality of laboratory analytic result data, rates of consent for specimen collection, and impact on retention. For more information, please refer to A.16.
Changes to 6-, 12-, and 24-Month Study Visits from a Consent Perspective
In the currently approved collection, the NCS gathers data via questionnaire only for the 6-, 12-, and 24-month study visits. Participants provide consent for their own involvement and permission for their children’s participation in the NCS in stages. Participating mothers provide written consent for their own participation when they join the Study. Mothers (or other legally authorized representative (LAR)) provide their written permission for children’s participation at two separate time points. First, the mother or LAR is asked to provide written permission for a child’s participation from birth through 6 months (using either the Birth Visit Information Sheet (sample collection) or the Birth Visit Information Sheet (no sample collection)) parental permission forms. Prior to the administration of the 6-month data visit, the NCS administers the Parental Permission for Child’s Participation (6-months through Age of Majority) to the mother or the child’s legally authorized representative. This form requests written permission for the NCS to collect information and samples involving enrolled children from six months through the child’s age of majority. The parental permission mentions that parents and guardians will be provided with descriptions of the data collection activities to be conducted during a particular visit at the start of that visit. As described in B.2.1, the NCS has used a series of visit-specific visit information sheets (VIS) for administration during in-person visits that involve questionnaire and/or specimen collection.
In the proposed information collection request, all visits which involve questionnaire administration, including the 6-, 12-, and 24-month visits, begin with the reading of the Multi-Mode Visit Introductory Script (VISCR). The VISCR describes what questionnaire topics will be covered during the visit, indicates incentives, provides an avenue for study participants to ask questions, and discusses the voluntary nature of participation. For visits where specimens will be requested, there are visit-specific written sample collection visit information sheets (VIS) describing the specimen collection requested of each participant at that visit. The respective VIS is administered directly after the VISCR. Documentation of consent for participation in specific specimen collections is not a part of VIS administration, consent or dissent for specific collections is provided verbally. When applicable, a VIS Sample Refusal Reconsideration Script for data collections that can be captured at one of multiple visits, is administered as part of the VIS administration to recognize that participants may choose not to provide specimens during the initial Study informed consent administration, but may choose to provide the specimen at a subsequent visit. The language of the script can be administered to caregivers of enrolled children as well as adult participants. Specifically new to this information collection request, NCS requests collection of child biospecimen and physical measures starting at 6 months of age of the child (in addition to data collection from questionnaires). As described above, the 6-, 12-, and 24-month visits include a reading of the Multi-Mode Introductory VISCR followed by reading and distribution of a hard copy Sample Collection VIS describing the specific sample collection and other procedures that will take place during the visit. Further details are mentioned in B.2.1.
Elimination of Data Collection during Preconception
In February 2012, the NCS halted recruitment for the three ARS arms, ending the follow-up of non-pregnant women for inclusion of what will become known as the preconception cohort of the Vanguard Study. In the ARS, two different screening tools were used in order to identify women who were likely to become pregnant. Now that recruitment has ended, the analysis on this study aspect is underway. In the Provider-Based Sampling Feasibility Study, the objectives are to define the feasibility, acceptability and cost of constructing a provider list frame, recruiting providers, and recruiting women early in pregnancy from providers. As the providers in this feasibility study will only recruit pregnant women, the NCS will no longer need to collect information from participants prior to pregnancy for the following data collection activities resulting in a reduction in respondent burden:
Pregnancy Screener (Two-Tier Low-Intensity)
Healthcare Provider Questionnaire
Household Enumeration Instrument
Low-Intensity Consent Script
Pregnancy Screener (Provider-Based Recruitment, Enhanced Household, Two-Tier High-Intensity)
Low-Intensity Invitation to High-Intensity Script
Non-pregnant Women's Informed Consent
Pre-Pregnancy Interview
Biological and Environmental Sample Collection (at preconception)
Pregnancy Probability Group Follow-Up Script
Low-Intensity Questionnaire (Non-Pregnant)
Pregnant Women’s Informed Consent (Provider-Based Recruitment, Enhanced Household, Two-Tier ONLY)
A.3 Use of Information Technology and Burden Reduction
Information technology solutions will be used, as appropriate, to limit respondent burden. This may include incorporation of previous information into the interview process, computer-assisted telephone interviewing, and information management solutions to ensure that the proper study components are administered at the appropriate times. Forms and questionnaires that are given to participants will be developed in user-friendly formats to reduce the time they take to complete.
Title II of the E-Government Act of 2002 requires federal agencies to conduct privacy impact assessments (PIAs) before developing or procuring information technology (IT) systems that collect, maintain, or disseminate personally identifiable information (PII). In 2007, NIH released Manual Chapter 1745-1, “Privacy Impact Assessments,” which reinforces the Department of Health and Human Services (HHS) requirement for PIA completion, and details NIH employee roles and responsibilities in support of this process.
PIAs provide a documented process, the purpose of which is to identify and protect employee and public citizens’ PII; and it ensures that the government has considered necessary safeguards for the PII passing through or being collected, maintained, or disseminated in its systems. The NCS must effectively manage participant safety while preserving data integrity and availability to carry out NCS activities. To do so, privacy risks associated with NCS systems are documented by having field contractors complete PIAs and include risks in the system plan of action and milestones (POA&M). The NICHD Chief Information Officer exercises appropriate oversight of contractors in carefully reviewing PIA information.
A.4 Efforts to Identify Duplication and Use of Similar Information
Before the planning and initiation of the NCS was launched, an inventory and review of longitudinal studies was conducted. The review examined whether the study goals could be addressed without embarking on an entirely new study. The systematic review of all available longitudinal cohort studies found no study capable of answering the questions and concerns that led to the proposed National Children’s Study regarding potential long-term effects in children from environmental exposures.
In addition, a systematic review was conducted to assess the information available to inform the experience of the Vanguard (Pilot) Study with respect to recruitment and retention. The review found that there was insufficient information to enable the NCS to determine the feasibility, acceptability, and cost of alternate recruitment strategies for enrollment of pregnant women into the NCS. The literature on recruitment and retention strategies in epidemiological and clinical research did not include sufficient research on recruitment into studies that were comparable to the NCS in size, length, longitudinal design, scope of coverage, diversity of participants, and types of information requested. Nonetheless, lessons from other studies were identified and incorporated into the Alternate Recruitment Substudy design. This collection is built upon the Alternate Recruitment Substudy outcome showing that provider-based recruitment is the most efficient means of identifying and enrolling eligible women into the NCS. However, provider-based sampling is a logical option that remains untested and has the potential to improve recruitment at a lower cost. Additionally, selected NCS Vanguard (Pilot) study visit assessment measures are continually revised based on data from the field. These revised measures now require testing before implemented responsibly in the NCS Main Study. User acceptance testing complements, but does not adequately replace, use and evaluation of measures in a large-scale data collection environment.
A.5 Impact on Small Business and Other Small Entities
We anticipate minimal impact on small businesses (for examples, health care providers such as physicians, nurses, and others) due to a relatively low amount of burden. Local NCS staff may work with physicians and other medical care providers or facilities to provide information about the study to their patients. With the consent of the participant, key medical diagnostic and treatment information on study participants may also be requested of medical providers. Where requested, the study will reimburse providers for any expenses incurred as part of filling requests for information.
A.6 Consequences of Collecting the Information Less Frequently
The schedule for collection of longitudinal data from NCS participants has been planned to coincide with important time periods for environmental exposures and developmental milestones for children. Women will be identified and enrolled in the earliest stages of pregnancy, so that early maternal and fetal exposures can be measured. Understanding how these contacts with study participants affect response rates and retention rates over time, particularly during the infancy and early childhood years, as well as data quality, will be essential to inform the methodology for the Main Study.
A.7 Special Circumstances Relating to the Guidelines of 5 CRF 1320.5
There are no special circumstances that would cause this information collection to be conducted in a manner inconsistent with 5 CFR 1320.5.
A.8 Comments in Response to the Federal Register Notice and Efforts to Consult Outside Agency
Comments in Response to the Federal Register Notice
The 60 day Federal Register Notice regarding the Provider-Based Sampling for the NCS Vanguard (Pilot) Study was published on pages 4569-4571 of the Federal Register on January 30, 2012. One comment was received in response to that notice. The commenter questioned the value of the National Children’s Study overall and suggested that the NCS be eliminated. The comment is reproduced below in its entirety:
our govt is getting entirely too nosy. the fat cat bureaucrats in skanky corrupt washinton dc. want to manage out kids bodies, instead of parents and now they seem to want to m anage our kids minds. it is time to downsize this out of control agency. this agency seems to find parents unacceptable. the budget for this proposal should be zero. this is invasive govt at work. the taxpayers of america do not want to be taxed to pay for this. this survey is not helping america, where l out of 2 americans are living in poverty. they are overtaxed to pay for the wastefulness of this agency.
Response to the comment: The National Children’s Study was mandated by Congress through the Children’s Health Act of 2000 (Public Law 106-310), which states:
PURPOSE.—It
is the purpose of this section to authorize the National Institute
of Child Health and Human Development* to conduct a national
longitudinal study of environmental influences (including physical,
chemical, biological, and psychosocial) on children’s
health and development.
(b) IN GENERAL.—The Director of
the National Institute of Child Health and Human Development* shall
establish a consortium of representatives from appropriate Federal
agencies (including the Centers for Disease Control and Prevention,
the Environmental Protection Agency) to—
(1) plan,
develop, and implement a prospective cohort study, from birth to
adulthood, to evaluate the effects of both chronic and intermittent
exposures on child health and human development; and
(2)
investigate basic mechanisms of developmental disorders and
environmental factors, both risk and protective, that influence
health and developmental processes.
(c) REQUIREMENT.—The
study under subsection (b) shall—
(1) incorporate
behavioral, emotional, educational, and contextual consequences to
enable a complete assessment of the physical, chemical, biological,
and psychosocial environmental influences on children’s
well-being;
(2) gather data on environmental influences and
outcomes on diverse populations of children, which may include the
consideration of prenatal exposures; and
(3) consider health
disparities among children, which may include the consideration of
prenatal exposures.
Efforts to Consult Outside Agencies:
Strategic advice and oversight is also provided by independent advisors through several groups as described below. Some of these committees are independent of the NCS; other committees comprise the NCS Program Office, study location staff, and independent advisors.
The Steering Committee consists of Principal Investigators from study locations as well as community representatives and provides first-level scientific guidance to the National Children’s Study. It is the arbiter of issues referred to it by the Program Office, the Principal Investigators, and the Executive Steering Committee. It is empowered to make protocol modifications that do not change the direction or cost of the study, subject to confirmation by the Program Office. The full Steering Committee meets face-to-face twice a year. Interim meetings by conference call are scheduled as needed.
The National Children’s Study Federal Advisory Committee (NCSAC), constituted under the Federal Advisory Committee Act, meets quarterly to provide strategic advice and recommendations to the Director of the National Institutes of Health, the Director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development, and the Director of the National Children’s Study regarding critical aspects of the study. These meetings are open to the public.
The National Children’s Study Federal Consortium consists of partner agencies with an interest in maternal child health, the environment, education and other topics. The Federal Consortium consists of about 20 Agencies and Departments and meets every 6 months to explore partnering and consultative opportunities, data sharing opportunities and technical advice and input on broad scientific topics.
The Independent Study Monitoring and Oversight Committee (iSMOC) monitors National Children’s Study data and the safety of study participants. The responsibilities of the iSMOC are to:
Monitor human subject safety through review and evaluation of accumulated study data
Review study conduct and progress
Make recommendations concerning continuation or modification of the study.
During the study, the iSMOC will review data regarding procedure-related adverse events; unanticipated problems involving risks to subjects or others; adherence to the protocol; factors that might affect the study outcomes or compromise the data (for example, protocol violations, losses to follow-up, breach of subject confidentiality); and barriers to study progress or completion (such as slow enrollment, new data or findings, other milestones, change in resources, rate of endpoint accumulation). The iSMOC will recommend appropriateness of notification and referral of individual participants for significant abnormal findings on testing of stored samples. The committee consists of 5 to 10 individuals not associated with the study. Committee membership reflects the disciplines and clinical specialties necessary to interpret study data and to evaluate subject safety.
A.9 Explanation of Any Payment or Gift to Respondents
To maximize response rate, many research studies, particularly those involving medical procedures, offer compensation for participants. For example, the National Health and Nutrition Examination Survey (NHANES) has offered their participants compensation since the 1970s. Incentives are effective in increasing response rates for in-person surveys and can help increase response rates especially for minorities and low-income households.
Participants in NCS will receive monetary and non-monetary incentives for their time, effort, and any expenses incurred (for example, transportation costs). The incentive amount will be determined by the amount of time required of the participant, as well as the type of activities that will be required. Incentive amounts will be consistent with the approved incentive schedule for the NCS Initial Vanguard Study and the Alternate Recruitment Substudy. Participants agreeing to provide biospecimen samples will be offered a monetary incentive or equivalent not exceeding $25. Compensation amounts will be addressed specifically in IRB submissions for each pilot. Small gifts of appreciation for participation may be provided to participants. These may include items such as t-shirts, tote bags, and are intended as tokens of appreciation.

A.10 Assurance of Confidentiality Provided to Respondents
The Provider-Based Sampling Feasibility Study for the National Children’s Study, NICHD will follow the same procedures and standards of confidentiality applicable to the Vanguard (Pilot) Study. Study data collected will be safeguarded closely and actions will be taken to protect participant confidentiality. Participants will be informed about the Certificate of Confidentiality (attached) granted to NCS to protect data from involuntary disclosure. The study locations, under contract to conduct the NCS, will have policies and procedures regarding confidentiality and protection of study data which will be reviewed and monitored by the NCS Program Office.
In addition to their own confidentiality procedures and policies, study locations will implement all federally required study-related confidentiality and data security procedures. All NCS Program Office staff, NCS study location staff, and other NCS contracting staff with access to NCS data must receive data confidentiality and security training provided by the NCS Program Office or its agent. These include completion of the NIH Information Security and Privacy Awareness Training, completion of a Human Subjects Protection Training, and signing an Assurance of Confidentiality or similar pledge that NCS data will only be used for the intended scientific purpose. All NCS Staff are required to complete security background checks consistent with the Office of Personnel Management requirements.
To further assure confidentiality of participant data, the study will employ rigorous methods to provide security for personal identifying information. Each field contractor, support contractor and the NCS Program Office will be required to submit an NCS Security Plan and Assessment that complies with the Federal Information Security Management Act (FISMA). This Security Plan will include: a) certification and accreditation of proposed data capture and case management software; b) configuration of those systems on study equipment; c) full disk encryption and two-factor authentication of study computers housing NCS data; and d) security assessment of the physical computing environment. After field contractors and support contractors complete the self-assessment of their security plans, the NICHD Chief Information Officer will review all study center security plans to determine the contractor’s authority to operate. Frequent and regular monitoring visits will assist in compliance with these terms.
Specific NCS data and materials to be collected, disclosure review, and data access are described in detail in the Data Access and Confidentiality Committee Manual. Principles and policies are available at http://www.nationalchildrensstudy.gov/about/organization/dacc/Pages/PolicyManualandDataUseAgreements.aspx; the manual is available to the public upon request. Specifically, all NCS data files will undergo disclosure review for personally identifiable information, using procedures consistent with or exceeding those named in Working Paper 22 of the Federal Committee on Statistical Methodology, and steps will be taken to appropriately manage disclosure risk. For example, genome-wide scans conducted on NCS specimens will be considered personally identifiable information and treated as such. Some biologic analyses (for example, HIV status, exposure to specific toxicants), results of some mental health screening tests, and reports of abuse are also considered sensitive.
A.11 Justification for Sensitive Questions
There are questions that may be contained in questionnaires that could be considered sensitive such as pregnancy status, reproductive and medical histories, and income. As part of the informed consent process, women will be informed that their participation in NCS is voluntary and that they may refuse to answer any question. Fathers and other family members may also be asked to participate through the informed consent process. Fathers or other family members will not be contacted without mothers’ agreement. All study questionnaires that would be proposed under this clearance mechanism have been or will be reviewed by Human Subjects Review Boards at NICHD and participating institutions. Each of these sensitive questions is necessary to allow comparisons between the Vanguard (Pilot) sample and persons potentially eligible for the Main Study, thereby informing whether proposed questionnaire items and biospecimen collections would warrant further testing in the NCS Vanguard Study.
A.12 Estimates of Hour Burden Including Annualized Hourly Costs
Estimates of annualized hour burden and annualized cost to respondents are laid out in Tables A.12-1 and A.12-2, respectively. The total number of estimated respondents is 31,082 annually. The total number of annual burden hours is 22,791. The estimated total annual respondent cost is $229,804.
By data collection activity, the number of estimated respondents varies based on two factors – the recruitment schema that are administered the data collection activity (for example, more participants receive the 18-Month Interview than the 12-Month Interview, because it is administered to Two-Tier Low-Intensity participants), as well as the retention estimates between study visits (for instance, we estimate 95% participation retention between the 12- and 18-month study visits).
The frequency of response varies by data collection activity. For instance, the tracing interview is a module which is administered at every study visit; therefore, the frequency response is 13, whereas the Pregnancy Visit 1 Interview is administered only once.
The average burden per response was determined by timing instruments and applicable files (for example, visit introductory scripts) that impose burden and the average burden per response for sample and physical measure collections are estimates based on field experience.
In general, study visits range between 15 minutes and 1 hour. Burden associated with biospecimen and environmental sample collection and physical measures collection differ based on what samples are collected (for instance, measuring blood pressure at 12 months only takes 10 minutes per respondent, while collecting blood, saliva and urine at 12 months takes 55 minutes).
Estimates of the total annual respondent cost for the collection of information use the appropriate wage rate categories. For individuals, the wage rate is $10.00 per hour. For health providers (OB/GYN) that receive the Provider-Based Sampling Frame Questionnaire, the wage rate is $101.13 per hour.
The cost of contracting out or paying outside parties for information collection activities is included in A.14.

*Postnatal biospecimen sample collections take place at 1 (breast milk – mother), 3 (breast milk - mother, 6 (infant urine), and 12 (infant urine, blood, saliva) months. We anticipate 3,044 responses (collections) per year over the three-year period (total: 9,132). As demonstrated in B.2, we anticipate that we will collect samples from approximately 3,850 mothers and children from September 2012 – July 2013. This period will represent the bulk of biospecimen sample collections for this age group. We do anticipate being within the requested burden over the three-year period.

A.13 Estimate of Other Total Annual Cost Burden to Respondents or Record keepers
NCS participants will be reimbursed for any expense resulting from their participation in the NCS in alignment with Table A.9. There are no additional costs associated with acquiring, installing, or utilizing technology and systems. In turn, there are no capital and start-up costs and there are no costs associated with operation and maintenance and purchase of services.
A.14 Annualized Cost to the Federal Government
The proposed information collection is estimated to cost about $71,904,774 per year over a three-year period. The annualized cost to the federal government is based on budgetary data for task orders that include costs of information collection, design, development, tests, printing forms, mailing list compilation and maintenance, mailing or enumeration, editing, coding, tabulation, analysis and publication of results. Salary and travel costs associated with project development, implementation, and monitoring are incorporated into the annualized cost to the federal government.
A.15 Explanation of Program Changes or Adjustments
This section describes program changes that are the result of deliberate Federal government action.
As noted in A.1 and A.2, the NCS halted ARS recruitment (Provider-Based Recruitment, Enhanced Household-Based Recruitment, Two-Tier Recruitment) in February 2012, eliminating the need for further screening and preconception data collection, which comprised the bulk of respondent burden in the Vanguard (Pilot) Study. This resulted in significantly decreased burden to the public. Currently, the NCS is approved for 159,966 annualized burden hours. In this information collection request, the total annualized hour burden for the ARS is approximately 15,000 annualized burden hours.
This request for revision proposes the addition of a Provider-Based Sampling Feasibility Study component of the Vanguard (Pilot) Study, supplemental measures involving Study Visit assessments, supplemental measures involving physical measurements, and supplemental collections involving biospecimens. These information collections, revisions of instruments, physical measure implementation, and biospecimen collections will evaluate the feasibility, acceptability, and cost of study design elements to inform the Main Study.
The NCS intends to use a modular approach for Study Visit assessments. The Core Questionnaire (described in A.2) is intended to be administered at multiple study visits, and will be piloted at the 30-month visit. A modular approach will also be instituted for the informed consent process (described in B.2.1.) and the Tracing Interview (described in A.2). In the long term, we anticipate that the modular approach mentioned above will result in reduced administrative burden as well as the potential for reduced participant burden.
To date, child physical measures have not yet been collected into the Vanguard (Pilot) Study. This collection will impose a relatively small amount of burden on the public. In addition, the re-introduction of child biospecimen collection into the Vanguard (Pilot) Study will also represent a relatively small amount of burden on the public.
To accommodate Department of Health and Human Services data standards for the Affordable Care Act Measures, the NCS has proposed a plan to incorporate questions on ethnicity, race, sex, primary language / language spoken, and disability status into existing Study Visit assessments that are asked of mothers, fathers, children, and primary caregivers, and range from before the child is born until 5 years of age. Upon finalization of this plan, this will result in a minimal public burden increase.
As mentioned in A.1, data collection at the seven Initial Vanguard Study locations will be conducted by a single contract research organization starting in July 2012. This transition has been planned to coincide with the expiration of Study Center contracts and the award of new contracts for administration of the Vanguard (Pilot) Study. For a period of 6 months, approximately 1,100 children will be followed via telephone or other remote data collection modes. This will not affect burden to the public.
NCS Proposed Implementation of the Data Collection Standards Pursuant to Section 4302 of the Affordable Care Act
The Affordable Care Act (ACA) includes several provisions aimed at eliminating health disparities in America. Section 4302 requires the Secretary of the Department of Health and Human Services (DHHS) to establish data collection standards for race, ethnicity, sex, primary language, and disability status. The law requires that, once established, these data collection standards be used, to the extent practicable, in all national population health surveys. In response to this statutory requirement, the NCS has proposed an implementation strategy that complies with the guidance standards for race, ethnicity, sex, primary language and disability status. For the current participants types (mother, father, primary care giver, and child) the inclusion of necessary questions has been incorporated into the following visits as outlined in Table A.15: (1) Pregnancy Visit 1, (2) Father Interview, (3) Child at birth, (4) Child at 60 months, (5) Primary Caregiver, and (6) Child ages 6 years of age and over. Currently, the oldest children in the NCS are approaching 30 and 36-months of age. The NCS Proposed Implementation of the Data Collection Standards Pursuant to Section 4302 of the Affordable Care Act was submitted to DHHS in March 2012 and approved on April 13, 2012.

Future Transition to Regional Operating Centers
As noted in Solicitation Number NIH-NICHD-NCS-SBSS-2012-07 (National Children’s Study Vanguard 2.0), the NCS will establish an NCS Vanguard Study Regional Operations Center (ROC) Network, which will consist of 4 Regional divisions of 10 current Study Locations based on geography: Central, East, South and West Regions. The goals of the solicitation will be to implement the next phase of the NCS Vanguard Study with a focus on the activities of data collection and evaluation, participant retention, study visit development and assessment and formative research on methods to address specific questions or needs. We anticipate that this transition will not adversely impact burden to the public. Further details on the solicitation are available online: https://www.fbo.gov/index?s=opportunity&mode=form&id=78a04a4e4845cef6339be27662eb935a&tab=core&_cview=1.
A.16 Plans for Tabulation and Publication and Project Time Schedule
Information collection for Phase 1 of the Alternate Recruitment Substudy of the Vanguard (Pilot) Study began in November 2010. Table A.16a describes the key evaluation questions for the Phase 1 recruitment strategies and retention measures with regard to feasibility, acceptability and cost (when applicable) of these collections. Phase 2, which began in the fourth quarter of 2011, added a questionnaire targeted to fathers and introduced biospecimen and environmental sample collection. Key evaluation questions for Phase 2 with regard to information collections, environmental and biospecimen collection and physical measures collection are described in Table A.16b. Key evaluation questions with regard to sampling, recruitment, and retention for the Provider-Based Sampling approach are described in Table A.16c.

Prior to posting a 60-day FR notice for the Main Study (projected January 2013), we will acquire at least 4 months of recruitment data using the Provider-Based Sampling approach described in this information collection request to meet the target of inviting 1,200 pregnant women, enrolling 960 eligible women at the first prenatal care visit. Estimating an 80% retention rate from the first prenatal care visit to the birth of the child, and assuming for this calculation that all of the enrolled women were enrolled in the prenatal stratum, this would result in approximately 750 child births over the course of the entire Provider-Based Sampling Feasibility Study. As noted in B.2, we expect that on average about 5 eligible women would be invited per provider location (approximately 20 per PSU) per month. Over the recruitment period, we expect 20 eligible women to be invited at each provider location, resulting in 400 pregnant women to be invited per PSU (1,200 total).Prior to posting a 30-day FR notice for the Main Study, we would have 8-9 months of recruitment and retention data to assess success of this approach. The Vanguard (Pilot) Study would continue to inform the Main Study visit design following the end of recruitment for Provider-Based Sampling. Please refer to Table A.16.d for more details for the Provider-Based Sampling Feasibility Study project time schedule.
