The respondent universe for ELS:2002 is described as is the sampling and statistical methodology proposed for the third follow-up full-scale study. We also describe methods for maximizing response rates, the special tests of procedures and methods, and the statisticians and other persons responsible for designing and conducting the study.
The target populations of the third follow-up full-scale study are the 2002 sophomore cohort and the 2004 senior cohort. The sophomore cohort consists of those students who were enrolled in the 10th grade in the spring of 2002, and the 12th-grade cohort consists of those students who were enrolled in the 12th grade in the spring of 2004. The sophomore cohort includes students who dropped out of school between 10th and 12th grade. Response rates through the second follow-up were high enough to expect large returns in the third follow-up of the study’s primary groups of interest: dropouts from high school, non-college bound high school graduates, and college-bound high school graduates (i.e., those who enrolled in college at time of last contact). The overall weighted response rate was 88 percent (89 percent unweighted). Response rates for respondents who had ever reported a dropout episode (~1200 cases) were about 83 percent for the second follow-up. Non-college bound students also make up a large part of the sample; about 30 percent of second follow-up respondents reported never enrolling in postsecondary education as of 2006.
The study population for the third follow-up consists of sample members who were enrolled in the 10th grade in the base-year study, or were enrolled in the 12th grade in the first follow-up study, and participated, at minimum, in either the base year or first follow-up rounds. The target population comprises all living members of the third follow-up 10th grade and 12th grade cohorts. In addition to the deceased, and to sample members who participated neither in the base year nor first follow-up, groups not followed for efficiency or practicality reasons include E sample members who consistently (across rounds) were physically or mentally incapable of participation. Post-tracing, the 2012 questionnaire will not be fielded to study members who are found to be: out of country, institutionalized, incarcerated, or “newly” incapable (having suffered a major cognitive or physical impairment). Sample members who have asked that their data be withdrawn from the study are eligible members of the sample frame, but will be treated as permanent nonrespondents and not fielded. Such eligible but nonfielded cases will be accounted for in the weighting and count against the response rate.
The ELS:2002 third follow-up full-scale sample will consist of approximately 16,200 sample members who were sophomores in 2002 or seniors in 2004 or both. The procedures that will be employed will target an overall response rate of 90 percent.
Our plan to maximize response rates focuses on two related goals of the ELS:2002 third follow-up data collection: (1) successful locating of sample members, and (2) a successful data collection.
The first goal is successfully locating and contacting sample members by successfully implementing a tracing and sample maintenance plan. A successful locating effort is dependent on a multitude of factors including the characteristics of the population, the age of the locating information for the population, and the completeness and accuracy of that information. The locator database for the cohort includes critical tracing information for most of the sample members, including their previous residences and telephone numbers. Moreover, Social Security numbers are available for 91 percent.
The tracing and sample maintenance plan includes, initially, the use of batch tracing services without direct respondent contact. Subsequently, direct mailings to sample members or their parents will take place. Batch tracing is a relatively low-cost method of updating addresses and telephone numbers for sampled individuals. The two primary batch tracing services include National Change of Address (NCOA) and Phone Append. NCOA will provide updated addresses for sample members, especially those who have recently moved. Phone Append will confirm or update the telephone number matched to each sample member at their most current known address. Cases whose contact information is not confirmed or updated by these steps will be sent for Accurint batch tracing. Using the updated address information obtained from these steps, the batch tracing activity will be followed with a direct mailing to sample members and their parents.
The inclusion of parents is an important support to the tracing and contacting goals of the study. Parents have been deeply involved in the study since its onset: parent permission was sought for student participation in the base year and first follow-up, and a parent survey was conducted in the base year. Parents have also previously been contacted for tracing and locating purposes. The age of the sample population makes it very likely that many of the sample members have recently gone through major life transitions. For students who entered postsecondary education (74 percent at the second follow-up), they are now more than 7 years past their initial entry point into postsecondary education and most students who persisted in their education are likely to have completed their certificate, associate’s degree, or bachelor’s degree programs. Sample members are unlikely to still be attending the undergraduate institution they were attending at the time of the second follow-up. Most of the sample members are now 25 or 26 years of age and have entered the workforce and started their careers. Some have married and changed names, making the task of updating their locating information somewhat more difficult. Another consideration is that 46 percent of adults aged 25 to 29 live in wireless telephone-only households,1 creating a greater locating challenge. For these reasons, we expect sample members’ parents to be a useful source for updating contact information for their children. Because parents’ residences will likely be more stable than their children’s, they will be very important to the tracing effort for a significant number of sample members. For this reason, the batch tracing activities and the sample maintenance mailings described in this plan will include parents. Also, study contacting materials will be produced in English, Spanish, and, on an at-need basis, up to four Asian languages, to facilitate contacts with parents whose first language is not English. Panel maintenance activities to facilitate sample locating were described fully in an earlier submission to OMB that obtained permission to contact sample members or their parents. These panel maintenance activities are currently ongoing.
We will also conduct batch tracing and intensive in-house tracing at RTI during data collection for cases we cannot locate. Immediately before beginning intensive tracing, batch tracing will be conducted on cases determined to have no good phone number in an attempt to keep costs as low as possible. If that step is unsuccessful, the case will be flagged for intensive tracing. The goal of intensive tracing is to obtain a telephone number at which the sample member can be reached. Tracing procedures may include (1) Directory Assistance for telephone listings at various addresses, (2) criss-cross directories to identify (and contact) the neighbors of sample members, (3) calling persons with the same unusual surname in small towns or rural areas to see if they are related to or know the sample member, and (4) contacting the current or last known residential sources such as the neighbors, landlords, and current residents of the last known address. Other more intensive tracing activities could include (1) database checks for sample members, parents, and other contact persons, (2) credit database and insurance database searches, (3) drivers’ license searches through the appropriate state departments of motor vehicles, (4) calls to colleges, military establishments, and correctional facilities to follow up on leads generated from other sources, (5) calls to alumni offices and associations, and (6) calls to state trade and professional associations based on information about field of study in school and other leads. The same vendors that were mentioned in the approved panel maintenance submission to OMB will be utilized.
Communication with sample members prior to and during data collection will promote cooperation by offering multiple methods for them to contact us (see Appendix 2 for contacting materials). The lead letters will provide the study website where sample members can find more information about the study and participating (by completing the questionnaire) via the Web. The letters will also provide telephone numbers respondents can use to contact RTI staff. Follow-up telephone calls will be used to determine whether sample members have in fact received the materials we will have mailed to them or visited the study website. Contact materials and the web site have been designed so as to be attractive and informative in a manner aimed to enhance participation in ELS:2002.
For those with Internet access, the first opportunity will be to complete a self-administered Web questionnaire. Instructions for completing the questionnaire via the website will need to be as clear and simple as possible to facilitate maximum web participation. Because it is not possible to ensure that all potential respondents will fully understand the instructions or that computer glitches will not occur, we will make it clear to potential web respondents that help desk staff will be available to them if and when they need them. Simply offering sample members a self-administered option is likely to increase response by allowing respondents greater discretion over how and when they can participate.
Despite the many advantages of offering a web survey mode, previous studies indicate that response rates are somewhat higher in interviewer-administered surveys than in self-administered surveys. Further methods of contact will include phone interviews and in-person interviews to increase contact with sample members over mail and Web contacts. Given the need to achieve high response rates, the interviewer training will focus considerable attention on enlisting cooperation. A large portion of the interviewer training for the third follow-up will concentrate on the most effective techniques for increasing participation. The two most important techniques on which interviewers will be trained are maintaining interaction with sample members and tailoring their approach to address the specific situation or concerns of potential respondents. An important part of these efforts is not only to highlight the importance of ELS:2002, but also to emphasize the importance of each respondent’s participation in the third follow-up survey. Exhibit B-1 summarizes the third follow-up full-scale data collection schedule and projected responses by survey mode.

The use of cell phone calling and text messaging is a relatively new means for contacting sample members. Little research has been conducted on the effects of text messaging on participation rates. Research conducted by Brick et al. suggests that text messaging as a method of prenotifying sample members has nearly equal response rates to control group counterparts (Brick, Brick, Dipko, Presser, Tucker, and Yuan 2007). According to Lambries et al., those households using primarily cell phones required more attempts to contact than those using both landline and cell phones and those using landline only (Lambries, Link and Oldendick 2006). Households that used cell phones primarily showed differences of 1.1 more attempts than landline-only household and 0.8 more attempts than both landline and cell phone households.
However, text messaging has some advantages as the first means of contacting sample members. Text messaging may help identify working numbers and, in turn, increase the efficiency of the calling process (Steeh, Buskirk and Callegaro 2007). The research by Steeh et al. concludes that text messages have two advantages as the first means of contact: outcome rates are substantially improved and information about the working status of the number is obtained. Further research in this field is needed to better understand the effects of cell phone calling and text messaging on participation rates. The previously approved panel maintenance mailings include a question asking sample members if they would like to receive a text message when data collection is about to begin.
RTI will draw upon its most effective strategies for increasing survey participation. In light of the field test results and recent discussions between OMB and NCES, ELS:2002 will move toward implementing a survey design with more responsive and adaptive features. ELS:2002 will move beyond response rates and toward a metric that better indicates bias reduction and stability in key estimates. The goal of this new metric will be to produce less-biased and more efficient estimates of key population parameters.
For ELS:2002/12, we propose to use a Mahalanobis distance function calculated at three points in data collection to identify nonrespondent cases which are most unlike existing respondents.
The following variables will be used to calculate the Mahalanobis distance:
Substantive data already collected/available from base year, first and second follow-up: enrollment status, parent’s education, high school completion status, test score quartile, income quartile, native English speaker, school control, school locale, postsecondary enrollment, current work status, and whether the case was in school in grade 12.
Paradata from current and prior rounds: response status from prior rounds, whether sample member contacted the help desk, whether sample member logged in but did not complete the questionnaire, number of contact attempts in the early data collection period, whether sample member made an appointment, and whether sample member told interviewer they would do the web interview. The Mahalanobis function incorporates a measure of the likelihood of ultimate response among current nonrespondents. Therefore, paradata are very important to include with the substantive data for factoring into the case-selection process thereby optimizing the selection itself.
Mahalanobis distance can be defined as the distance between a case and some group centroid. Therefore, cases with larger distance scores can be thought of as cases demonstrating large differences from the group. That is, these cases would be characterized by differences, for example, in their enrollment status, parent’s education, high school completion status, etc.
Identifying these cases and presenting the specifically-targeted nonresponding cases with a higher incentive will in turn attempt to boost their participation and potentially reduce bias in estimates and also improve analytic power through higher sample sizes for these groups of cases of analytic interest. Cases identified for targeting via their Mahalanobis distance (nonrespondent cases with distance scores furthest from the mean respondent) will receive a $55 incentive – rather than the $25 base incentive – in an attempt to encourage their participation. We should note that ever-dropout cases are a critical set of cases and will receive $55 from the start of data collection rather than being included in the Mahalanobis distance measure selection process during data collection. The approach with ever-dropouts is based on the particular difficulty gaining cooperation from this important subgroup as demonstrated during the F3 field test and prior rounds of data collection.
We propose to measure the distance functions at three points during data collection. At these points, the cases with the largest distance scores will be offered the $55 incentive while the $25 base incentive will remain intact for all other cases. Other activities that will be conducted to locate and interview targeted cases include performing pre-data collection intensive tracing, pursuing the cases in person with field locator/interviewers, and sending a $5 prepaid incentive near the end of data collection. The case-identification for more-intensive effort will be done at three points during data collection.
Our first target-case-selection point will be right before outbound CATI is scheduled to begin, 4 weeks into data collection.
The second point will be right before the CAPI period begins, 9 weeks into data collection.
The third point will be just prior to the pre-paid incentive period, approximately 8 weeks prior to the end of data collection.
At each juncture, the cases targeted will be those with the largest distance scores but not targeted in the prior phase(s). Also at the third and final point, cases identified for targeting will receive a $5 prepaid incentive in addition to the $55 incentive and other non-monetary activities, listed above. At this late point in data collection, these cases are likely to be the most critical for reducing the final mean distance function scores between respondents and nonrespondents, thus potentially improving analytic power in terms of sample size and reducing bias in estimates. We believe it prudent to be highly strategic with the use of prepaid incentives, which are normally very effective. Again, cases not targeted will continue to be offered the $25 incentive and will not be targeted for the more-intensive non-monetary activities.
Case targeting will be based on distance scores and anticipated yield. Based on the proportion of interviews projected across each of the phases of data collection, the distance scores will be segmented such that the following approximate numbers of cases are to be targeted at each cut point: 915 cases at the first cut point, 760 cases at the second cut point, and 830 at the third cut point. At each of these time points, we will evaluate the Mahalanobis values among the respondents and nonrespondents to identify the target cases.
In summary, plans include classifying all cases that have ever dropped out of high school as a special group to target prior to data collection and offering them a $55 incentive from the start of data collection. Using the Mahalanobis distance function, special target cases will be identified at the three points during data collection. These cases will be offered an increased incentive of $55 in an effort to encourage participation and reduce the risk of bias.
The key to a successful third follow-up data collection will be combining all survey design elements into a comprehensive and effective strategy.

The TRP recommended adding a question asking whether respondent had received, applied for, or been eligible for unemployment compensation. As with the newly-added item F3LOOKJOB, this unemployment question helps distinguish the unemployed from discouraged worker, but covering a span of persistent high unemployment in the country. Actual wording from B&B:93/03 is “Since 1997, have you ever received unemployment compensation while you were unemployed and looking for work?” |

Per TRP recommendation, removed "or partnered with" from question wording since existing research indicates not being married (as opposed to not being married or partnered) is the primary distinction in determining whether having a child might interfere with other education/employment-related activities.

Now we’d like to collect some information about your current living arrangements. What is the 5-digit ZIP code for your current residence? |
Though the FT instrument did in fact collect respondent’s ZIP-code in the course of collecting an address to which the incentive check should be mailed, that “incentive ZIP code” (1) may differ from the respondent’s residential zip code, and (2) is provided by the respondent not as a deliverable data element per se, but as information necessary for them to receive their incentive payment. In hopes of including the respondent’s “residential zip code” on the restricted-use datafile (such that researchers are better able to track outcomes, e.g. movement for employment and post-secondary education, intergenerational wealth, and calculating SES) we would like to include a survey item explicitly asking for the respondent’s residential ZIP code. Please note that the wording shown in the “Old Wording” column will still be used at the end of the F3 questionnaire such that an incentive address is obtained. |

Since the majority of FT respondents indicated 0 respondents when answering F3DEPENDENT, added this simple yes/no gate question (F3DPNDNT) in hopes of shortening the average interview length; also, to improve clarity, revised item wording to read "Number of dependents less than age 18" (as opposed to "Number of dependent children") and "Number of dependents age 18 or older" (as opposed to "Number of dependent adults"). |

As part of ELS:2002, linkages will be developed with several existing data sources to supplement the student interview data. Because certain data (for example, specific financial aid amounts and associated dates) can only be accurately obtained from sources other than the student or parent. Through the experience of gathering data for many National Center for Education Statistics (NCES) studies, including previous ELS:2002 data collections, Baccalaureate and Beyond Longitudinal Study (B&B), National Postsecondary Student Aid Study (NPSAS), and Beginning Postsecondary Student (BPS) study, considerable knowledge has been gained performing file merges with external sources of data, including Department of Education’s (ED) Central Processing (CPS) for Free Application for Federal Student Aid (FAFSA) data, the National Student Loan Data System (NSLDS), and the General Educational Development (GED) Testing Service. For this study, we propose to merge ELS:2002 files with the following datasets: GED, CPS, and NSLDS.
The Family Educational Rights and Privacy Act (FERPA), (34 CFR Part 99) allows the disclosure of information without prior consent for the purposes of ELS:2002 according to the following excerpts: 99.31 asks “Under what conditions is prior consent not required to disclose information?” and explains in 99.31 (a) that an educational agency or institution may disclose personally identifiable information from an education record of a student without the consent required by 99.30 if the disclosure meets one or more specific conditions. ELS:2002 collection falls under Sec. 99.31 (a)( 3). The disclosure is, subject to the requirements of Sec. 99.35, to authorized representatives of--
The Comptroller General of the United States;
The Attorney General of the United States;
The Secretary; or
State and local educational authorities.
ELS:2002 is collecting data under the Secretary’s authority. The personally identifiable information is collected from student record systems with adherence to the security protocol detailed in 99.35: “What conditions apply to disclosure of information for Federal or State program purposes?”
(a)(1) Authorized representatives of the officials or agencies headed by officials listed in Sec. 99.31(a)(3) may have access to education records in connection with an audit or evaluation of Federal or State supported education programs, or for the enforcement of or compliance with Federal legal requirements that relate to those programs.
(2) Authority for an agency or official listed in Sec. 99.31(a)(3) to conduct an audit, evaluation, or compliance or enforcement activity is not conferred by the Act or this part and must be established under other Federal, State, or local authority.
(b) Information that is collected under paragraph (a) of this section must:
(1) Be protected in a manner that does not permit personal identification of individuals by anyone other than the officials or agencies headed by officials referred to in paragraph (a) of this section, except that those officials and agencies may make further disclosures of personally identifiable information from education records on behalf of the educational agency or institution in accordance with the requirements of Sec. 99.33(b); and
(2) Be destroyed when no longer needed for the purposes listed in paragraph (a) of this section.
(c) Paragraph (b) of this section does not apply if:
(1) The parent or eligible student has given written consent for the disclosure under Sec. 99.30; or
(2) The collection of personally identifiable information is specifically authorized by Federal law.
Secure Data Transfers. NCES has set up a secure data transfer system, using their NCES member site with Secure Sockets Layer (SSL) technology, described above. The study contractor, RTI, will use this electronic system for submitting data containing potentially identifying information (such as SSNs, names, and dates of birth of our sample members) along with their survey ID (not the same ID that is available on the restricted-use data). Before being transmitted, files will be encrypted using FIPS 140-2 validated encryption tools. RTI will receive data from the NCES system as well. The system requires that both parties to the transfer be registered users of the NCES Members Site and that their Members Site privileges be set to allow use of the secure data transfer service as described above. This process will be used for all file matching procedures described below, except in instances when the vendor already has a secure data transfer system in place.
RTI will perform file merges with the CPS data containing federal student aid application information. The merge with CPS can occur at any time for any number of cases, provided that the case has an apparently valid SSN associated with it. RTI sends a file to CPS and receives in return a large data file containing all students who applied for federal aid. Programs and procedures are in place to prepare and submit files according to rigorous CPS standards. Similarly, programs and procedures are in place to receive and process data obtained from CPS.
RTI will electronically upload a file on the FAFSA secure web-site for matching which contains SSN and the first 2 letters of the sample member’s last name (but no other information). Access to the site for the upload is restricted to authorized users who are registered and provide identification/authentication information (SSN, DOB, and personal identification number [PIN]) to the FAFSA data site. The file is retrieved by the Central Processing System or CPS (the FAFSA contractor data system) for linkage. The linked file, containing student aid applications for matched records, is then made available to RTI only through a secure connection (EdConnect) which requires username and password. All CPS files will be processed, edited, and documented for inclusion on the analytic data files.
RTI will also conduct a file merge with the NSLDS to collect federal loan and Pell grant data. The resulting file will contain cumulative amounts for each student’s entire postsecondary education enrollment. Programs exist to create the files for the merge and others to read the received data. All matching processes are initiated by RTI staff providing a file with one record per sample member. File transfers will use the NCES secure data transfer system described above.
RTI will also conduct a file merge with the GED testing service, as was done in ELS:2002/06 to obtain GED test dates and results. This will extend the coverage for the ELS:2002 sample regarding attempts for high school equivalency credentialing. File transfers will use the NCES secure data transfer system described above.
The data from all of these sources, as allowed by the vendor, will be delivered in the restricted-use data files and will be useful for creating derived variables. The variables – both direct and derived – will be documented thoroughly for the data files.

Under a contract with NCES, modeled on the Responsive Design methodologies developed by Groves (Groves and Heeringa, 2006), RTI is currently developing new approaches to improve survey outcomes that incorporate different responsive and adaptive features. After sample members with the lowest response propensities are empirically identified, they are targeted with interventions in an attempt to encourage participation. Inclusion of low propensity cases has the potential to ameliorate increases in standard errors arising from non-response adjustments. To inform main study operations, design, and content, ELS:2002 includes a field test sample. To estimate a case’s response propensity prior to the start of the ELS:2002 third follow-up field test, a sample member’s eventual response status in the ELS:2002 second follow-up field test was predicted. A logistic regression model was fitted with the sample member’s ELS:2002 second follow-up field test response status as the dependent variable. As independent variables, a range of information known for all respondents and nonrespondents from each prior wave of the longitudinal field test, including information from batch tracing activities were examined for significance. The following variables were considered as predictors of a field test sample member’s second follow-up field test response outcome: base year response status, first follow-up response status, whether the respondent ever refused, whether the respondent has ever scheduled an appointment, whether the respondent was classified as hard to reach, the number of calls made to the respondent in the second follow-up, high school completion status, parental level of education, high school type, urbanicity, dropout status, and the sample member’s postsecondary aspirations.
No information about the race, gender, or any other demographic characteristics of the sample members was used for prediction.
Predicted probabilities derived from the logistic regression model were used to get an estimate of a case’s response propensity for the third follow-up field test. Cases were split into two groups of equal size. Field test sample members above the median response propensity were classified as high propensity, and those below the median as low propensity. In total, 528 cases were classified as high propensity and 527 as low propensity. For the implementation of the experiment, the 527 low propensity cases were randomly split into experimental and control groups. The goal was to examine how well low propensity cases using prior wave data can be predicted and how these should be treated to change their response propensity.
Since low propensity cases assigned to the experimental group received treatment, of interest was how those cases were distributed according to their prior response status. Exhibit E-1 shows the distribution.

As shown in Exhibit E-1, the low propensity cases consisted of both respondents and nonrespondents in all prior waves of ELS:2002. Also, high propensity cases were not limited to second follow-up respondents. A number of nonrespondents were classified as high propensity. This suggests that for ELS:2002 prior round response status, while important, may not be sufficient as a predictor of response outcome in the third follow-up and should not be the sole basis for partitioning cases into propensity categories.
Exhibit E-2 shows the distribution of the case propensities across some demographic characteristics of interest. From the data, it is clear that the demographic distribution of the propensities approximates the distribution in the overall FT sample. There is no obvious skewing across these demographic characteristics.

The basic premise of the response propensity approach is to identify low propensity cases as early as possible and assign to them modified treatments. In theory, treating low propensity cases in the same manner as high propensity cases is inefficient and possibly harmful to overall data quality. The special treatment for ELS:2002 field test low propensity cases was a higher incentive of $45 at the start of data collection (weeks 1-9) and going up to $55 starting at week 10. High propensity and control group cases were offered $25 until week 10 of data collection, after which the incentive increased to $35. Exhibit E-3 outlines the timing and levels of the different incentives.

Results of the Field Test Response Propensity Experiment
The predictive model developed ahead of the field test data collection effectively predicted the eventual response outcome for sample members. The high propensity group’s response rate (67.4%) was significantly higher than that of the low propensity control group (45.4%). This difference was statistically significant (χ2 = 34.9; p < .0001). In examining the effect of the higher incentive treatment for low propensity cases, a numerical difference in participation (51.6% for treatment cases v. 45.4%) was observed, however, the difference was not statistically significant. The increased incentives corresponded to a 6 percent observed increase in response rate for the low-propensity cases. However, the small ELS:2002 field test sample size and the brevity of the data collection period may have contributed to the inability to detect a significant difference in the results.

Mean relative bias was also examined (refer to Exhibit E-6). It is calculated by finding the simple average of a set of relative biases. For the field test analysis, 23 relative biases were calculated from seven variables (sex, race, ever dropout status, high school completion status, base-year school type, base-year urbanicity, and base-year school FIPS state code), and the mean relative bias was calculated by calculating their simple average.

Bias is defined as the weighted absolute difference between an estimate calculated using respondents only and an estimate calculated using nonrespondents only. The weight for a bias is defined as the nonresponse rate associated with the bias calculation. A relative bias is calculated by dividing the bias by the estimate calculated using both respondents and nonrespondents. In reviewing the mean relative bias shown in Exhibit E-6, it appears that including low propensity cases in the dataset may help reduce bias (even if slightly), and that the higher incentive for the low propensity experimental cases may have lowered the bias relative to the low propensity control group.
The response propensity model successfully predicted response outcome. The inclusion of low propensity cases showed an apparent reduction in unit-level biases. Including more low-propensity cases in the data may reduce bias and may help improve final estimates since low-propensity cases appear to be different in terms of their survey responses. A higher incentive amount produced an observed higher response rate for low propensity cases. It is not known how the experiment would have concluded if the field test data collection had continued two additional months to its scheduled end. The data collection ended two months early because the interview yield goal was met. If data collection had continued, more cases would have been traced and located, and more cases would have been successfully reached and interviewed. Please refer to B.3 for full scale study recommendations.
While the propensity modeling approach yielded some positive outcomes, for ELS:2002/12 full scale study, we propose to use a Mahalanobis distance function calculated at three points in data collection to identify nonrespondent cases which are most unlike existing respondents. The goal remains to identify cases during data collection that exhibit large differences from the mean respondent case. Doing so provides an opportunity to target (i.e. with incentives) during nonresponse follow-up, those cases most likely to reduce nonresponse bias. The distance function approach may provide a better opportunity to target cases that exhibit differences across a larger number of variables, rather than relying on propensity to respond.
The following variables will be used to calculate the Mahalanobis distance:
Substantive data already collected/available from base year, first and second follow-up: enrollment status, parent’s education, high school completion status, test score quartile, income quartile, native English speaker, school control, school locale, postsecondary enrollment, current work status, and whether the case was in school in grade 12.
Paradata from current and prior rounds: response status from prior rounds, whether sample member contacted the help desk, whether sample member logged in but did not complete the questionnaire, number of contact attempts in the early data collection period, whether sample member made an appointment, and whether sample member told interviewer they would do the web interview. The Mahalanobis function incorporates a measure of the likelihood of ultimate response among current nonrespondents. Therefore, paradata are very important to include with the substantive data for factoring into the case-selection process thereby optimizing the selection itself.
Mahalanobis distance can be defined as the distance between a case and some group centroid. Therefore, cases with larger distance scores can be thought of as cases demonstrating large differences from the group. That is, these cases would be characterized by differences, for example, in their enrollment status, parent’s education, high school completion status, etc. Identifying these cases and presenting the specifically-targeted nonresponding cases with a higher incentive will in turn attempt to boost their participation and potentially reduce bias in estimates and also improve analytic power through higher sample sizes for these groups of cases of analytic interest.
Cases identified for targeting via their Mahalanobis distance (nonrespondent cases with distance scores furthest from the mean respondent) will receive a $55 incentive – rather than the $25 base incentive – in an attempt to encourage their participation.
We should note that ever-dropout cases are a critical set of cases and will receive $55 from the start of data collection rather than being included in the Mahalanobis distance measure selection process during data collection. The approach with ever-dropouts is based on the particular difficulty gaining cooperation from this important subgroup as demonstrated during the F3 field test and prior rounds of data collection.
We propose to measure the distance functions at three points during data collection. At these points, the cases with the largest distance scores will be offered the $55 incentive while the $25 base incentive will remain intact for all other cases. Other activities that will be conducted to locate and interview targeted cases include performing pre-data collection intensive tracing, pursuing the cases in person with field locator/interviewers, and sending a $5 prepaid incentive near the end of data collection. The case-identification for more-intensive effort will be done at three points during data collection.
Our first target-case-selection point will be right before outbound CATI is scheduled to begin, 4 weeks into data collection.
The second point will be right before the CAPI period begins, 9 weeks into data collection.
The third point will be just prior to the pre-paid incentive period, approximately 8 weeks prior to the end of data collection.
At each juncture, the cases targeted will be those with the largest distance scores but not targeted in the prior phase(s). Also at the third and final point, cases identified for targeting will receive a $5 prepaid incentive in addition to the $55 incentive and other non-monetary activities, listed above. At this late point in data collection, these cases are likely to be the most critical for reducing the final mean distance function scores between respondents and nonrespondents, thus potentially improving analytic power in terms of sample size and reducing bias in estimates. We believe it prudent to be highly strategic with the use of prepaid incentives, which are normally very effective. Again, cases not targeted will continue to be offered the $25 incentive and will not be targeted for the more-intensive non-monetary activities.
Case targeting will be based on distance scores and anticipated yield. Based on the proportion of interviews projected across each of the phases of data collection, the distance scores will be segmented such that the following approximate numbers of cases are to be targeted at each cut point: 915 cases at the first cut point, 760 cases at the second cut point, and 830 at the third cut point. At each of these time points, we will evaluate the Mahalanobis values among the respondents and nonrespondents to identify the target cases.
We computed Mahalanobis values over time with the second follow-up data to identify variables for the third follow-up and to get a feel for how the metric will be implemented in the third follow-up. Exhibit E-7 shows the Mahalanobis distance function calculated by month of data collection in the ELS:2002 second follow-up main study.
As shown in Exhibit 7, over time in the second follow-up, the distance between respondents and nonrespondents grew slightly larger indicating that these groups may have become more dissimilar as data collection proceeded. The differences in mean distance scores between respondents and nonrespondents were not significant. However, this is illustrative of the potential benefits of carefully monitoring these values over time. If the differences were significant at the end, the risk of bias would have been increased. The goal for the ELS:2002 responsive design in the third follow-up full scale study will be to attempt to minimize the distances between respondents and nonrespondents over the course of data collection and therefore, reduce the risk of nonresponse bias.
