A1. Identification of the Information Collection

1(a) Title of the Information Collection

TITLE: National-Scale Activity Survey

EPA ICR No.: 2293.01

OMB Control No.: 2060-NEW

1(b) Short Characterization/Abstract

EPA supports the Air Quality Index (AQI), a program that uses data from air quality monitors to forecast pollution levels and to notify the public of health hazards associated with air pollution, primarily ozone and particulate matter pollution (PM). EPA, and specifically the Office of Air Quality Planning and Standards, which manages the AQI program, is interested in assessing the public’s awareness, knowledge and both stated and actual behavioral response to AQI warnings. To address this need, OAQPS wishes to conduct the National-Scale Activity Surveys (N-SAS) to gather information on perceptions, awareness, attitudes, and stated and actual behaviors in response to AQI warnings.

EPA is requesting permission from OMB to conduct a survey of 1,600 individuals age 35 or older who meet minimal activity requirements living in Washington, D.C.; Sacramento (also other cities in San Joaquin Valley -- San Joaquin, Stanislaus, Merced, Madera, Fresno), Chicago, Dallas, Houston, Atlanta, Philadelphia, or St. Louis. The data will be collected through a web-based survey of members from Knowledge Network’s web panel.

The N-SAS consists of a series of nine surveys. A screening survey at the beginning and a debriefing survey at the end will provide information on the research participants, their awareness and knowledge of air pollution and the Air Quality Index (AQI), risk perceptions regarding health effects, and reported behaviors on high ozone days. After the screening survey, research participants will be administered a set of seven activity diaries administered on both high and low ozone days to collect information on actual behavior.

The information obtained from N-SAS will be used by EPA to assess hypotheses for the N-SAS research participants regarding

Extent of awareness of and knowledge about the AQI
The effects of the AQI-based warnings on behavior in eight cities with significant pollution problems
The correlation between awareness, knowledge, stated behavior on high pollution days and data on behavior reported in the activity diaries
Differences in behavior, awareness and knowledge among different sub-samples of the N-SAS research participants

In addition to assessing the effectiveness of AQI-based ozone warnings, the data will also be used to supplement the limited data available to develop exposure profiles for older Americans.

The goal of N-SAS is to provide insights into awareness, knowledge and behavior related to the AQI. The N-SAS survey will be conducted using the Knowledge Networks web panel as the sampling frame and therefore, any observations or conclusions drawn from the survey are most relevant to that sampling frame. Although the Knowledge Networks panel is recruited using an RDD sampling frame, the final panel differs from the U.S. population along a number of key demographic dimensions and the unobserved characteristics of individuals who participate in web panels may differ from the overall U.S. population. Because of this, there would be significant uncertainty associated with extrapolation of the results of this analysis to a broader population beyond the Knowledge Networks panel members who meet the eligibility criteria for this study. This study is exploratory in nature and is not intended to be used as a formal program evaluation or to obtain generalizable estimates; however, EPA expects that it will provide some useful insights on the current AQI program.

A2. Purpose and Use of the Information Collection

Need/Authority for the Collection

The motivation for the National-Scale Activity Survey (N-SAS) originated with a desire to assess the impact of the U.S. Environmental Protection Agency (EPA) programs and regulations to improve air quality on the U.S. population. Both internal and external reviews recommended increasing the use of indicators that track changes in the health and well-being of individual citizens to supplement measures of ambient air quality that EPA has traditionally reported. To determine whether these information policy tools actually increase precautionary behaviors, the Clean Air Act Advisory Committee recommended that EPA “study effects of air quality index [AQI] advisories on exposure-reduction behaviors and whether behaviors lead to health benefits” (Air Quality Management Workgroup, 2004).

EPA also needs the information to improve exposure profiles of older Americans used to assess the impact of regulations. The data collected by this survey will be incorporated in EPA’s Consolidated Human Activity Database (CHAD).

Practical Utility/Users of the Data

Currently, little data exists that can be used to systematically evaluate whether and how the information in AQI warnings is received, processed, understood, and used by the public to protect themselves against the health risks associated with ozone and as a prompt for emission reduction activities. The existing studies we have identified are discussed in Section A4 below. The longitudinal N-SAS will provide data that will have a number of direct, practical uses for EPA and for policy makers at the state and local level.

Assess the effectiveness of AQI-based warning systems
Examine the correlation between awareness, risk perceptions, knowledge, stated behavior and actual behavior within our sample.
Identify subgroups within the set of N-SAS research participants that may need more targeted education on air pollution risks.
Supplement and update the sparse set of activity data on older Americans currently in CHAD.
Metropolitan areas must report past ambient levels of criteria pollutants to EPA, but the forecasting data used for the AQI-based warnings is provided voluntarily. The data collected by N-SAS will help policy makers and other researchers better understand how the forecasted warnings are understood and where adjustments might be made to the information provided in the warnings.

This study is exploratory in nature and is not intended to be used as a formal program evaluation or to obtain generalizable estimates; however, EPA expects that it will provide some useful insights on the current AQI program.

A3. Use of Improved Technology and Burden Reduction

The N-SAS survey data will be collected through a web-based survey. Utilization of the World Wide Web has the advantages of allowing respondents to complete as much of the survey as desired in one sitting and to continue the survey at another time, minimizing the possibility of respondent error by electronically skipping questions that are not applicable to a particular respondent, and creating the least burden to the respondent. In addition, respondents will be notified of the survey by email. In order to collect activity diary data on both high ozone days and other days with a sample of 1600, the activity diary surveys must be administered on specific days when appropriate weather and ozone conditions are forecast. Using email survey invitations and a web-based survey instrument, respondents can easily be notified of surveys on specific days. For N-SAS we plan to send an email two days before the activity diary will be sent and a reminder email after it is sent. Finally, we will use the web-based survey structure to minimize recall bias by limiting the time the respondent has to take the survey to 48 hours after the specified day.

One alternative method considered was to conduct telephone surveys. Given the need to survey individuals based weather and ozone condition forecasts, the telephone survey method was unsuitable. According to companies that conduct telephone surveys, call centers typically do not have excess staff that can be mobilized with a day or two notice to phone a couple hundred respondents on a specific day. In addition, telephone surveys are conducted when the respondent answers the phone, rather than at the convenience of the respondent. The American Time Use Survey (ATUS) is conducted by phone. Unlike the N-SAS activity diaries, the ATUS does not need to be conducted on a specific day. The ATUS suffers from potential bias resulting from the difficulty of reaching people who are active and frequently out of the house by phone. Use of a web-based survey will help alleviate this source of bias because respondents can take the survey when they want to. Finally, response rates for telephone surveys are decreasing as new technology (answering machines, voice mail, caller identification) becomes available, and non-locate rates in later waves of longitudinal telephone surveys are increasing, likely due to increased use of cellular phones and frequent switching of carrier companies. In sum, because of the disadvantages of alternate modes of administration and because our research objectives could not be fully met without a high response rate among selected respondents, we determined that the study design of collecting data via Web surveys was the best methodology.

A4. Nonduplication

RTI conducted a search of the literature to assess the availability of data on both awareness and knowledge of the AQI and activities on both high ozone days and other days. Relatively few surveys have measured awareness of the AQI, reported and actual behavior and air pollution risk perceptions. The surveys and research activities summarized below represent the most prominent related literature of which we are aware.

STAR grant survey: Dr. Mansfield (RTI) and colleagues at RTI and UNC conducted the most similar survey (funded under the STAR grant program, EPA agreement 8295440). In addition to Dr. Mansfield, the project team included Dr. George Van Houtven (RTI), Dr. Zachary Pekar (before he left RTI to work at EPA), Dr. F. Reed Johnson (RTI) and Dr. Douglass Crawford-Brown (Environmental Sciences and Engineering, University of North Carolina). The project included a set of activity diaries, a baseline survey and a debriefing survey to measure awareness of the AQI. The sample for the survey included parents of young children, half of whom suffered from asthma, living in metro areas with high ozone pollution recruited from the Harris Interactive web panel (an opt-in web panel). Publications and presentations from this grant include (Mansfield et al. 2006, Mansfield 2006, Mansfield et al. 2005)
EPA has included a small set of questions on the Roper Green Gauge Survey to measure awareness of the AQI.
RTI International’s 2000 Health and Aging Survey included a set of questions about the awareness of the AQI as part of a longer survey administered using Knowledge Network’s web panel (Mansfield and Corey 2003).
The 2006 BRFSS included a module with four questions about awareness of the AQI and reported behavior change. Seven states chose to administer the module.
Bresnahan, Dickie, and Gerking (1997) collected activity data through telephone interviews from a panel of adults in the Los Angeles area who were contacted between 2 to 5 times over a 12-month period to study the impact of ambient pollution levels (not AQI-based alerts).
Individual metropolitan areas have conducted surveys on awareness of the AQI or other air pollution campaigns.
In addition to these surveys, some research has been done linking air quality alerts or warnings to aggregate daily changes in attendance at outdoor events, hospital admissions, health outcomes and driving (for example, Neidell 2004, Neidell 2005, Neidell 2007).

Overall, the research and other surveys suggest that some individuals, but not all, are aware of AQI-based warnings and respond by changing their behavior. In a series of studies, Neidell finds evidence consistent with behavioral response to AQI alerts by children and older adults. Neidell (2005) examined attendance at a selection of outdoor events in southern California (Los Angeles Zoo, Griffith Park Observatory, and the Los Angeles County Arboretum and Botanical Gardens). Neidell found that participation was 3% to 11% lower on days forecasted to be smog alerts, which was most significant in for children and older adults. The study used attendance at outdoor facilities as proxy for the amount of time spent outdoors. Neidell (2002) combines individual child asthma-related hospitalization data with ZIP-code-level population demographics, found a negative, significant relationship between health advisories (proxies for avoidance behavior) and hospitalizations. In similar work, Neidell (2004) found evidence that for children and older adults, but not adults, smog alerts lead to a decrease in asthma hospital admissions. Families of high socioeconomic status display particularly strong patterns of avoidance behavior.

Bresnahan, Dickie, and Gerking (1997) used data from a panel of adults in the Los Angeles area who were contacted between 2 to 5 times over a 12-month period. Their results indicated that the study individuals did change their behavior in response to poor air quality by reducing time spent outside on a day-to-day basis, however the study looked at the impact of ambient pollution levels rather than AQI-based alerts.

In the RTI Health and Aging Survey (see third bullet above) of over 6,000 respondents, 57% of individuals who were aware of the ozone alert system and lived in a county that experienced at least one red day over the previous summer reported reducing their outdoor time on high ozone days (Mansfield and Corey 2003). People who were not working at least part-time, including homemakers, the unemployed, students and retirees were more likely to report reducing the time they spent outdoors on high ozone days. Furthermore, people who reported excellent or good health were less likely to report reducing outside time on high ozone days compared to people with fair or poor health.

The STAR grant project (PI Dr. Mansfield, described in the first bullet above) found that parents with asthmatic children were more likely to say they checked the air quality forecast more frequently, and the more severe the asthma the more frequently the parents said they checked the forecast. Families with more young children stated that on average they checked the forecast less frequently, as did white parents. In the debriefing survey parents were asked what they do if they hear that high levels of air pollution are forecast, including (1) whether they have their child spend less time outdoors or (2) whether they have their child do less strenuous activities. Over two-thirds said they spend less time outdoors and 39 percent said they have their child do less strenuous activities. Again, analysis of the data suggests that the presence of an asthmatic child has a positive and significant effect on both stated averting behaviors. In addition, both behaviors were more likely in areas with a history of air pollution problems and in cities with higher summer temperatures. Households with more young children were significantly less likely to say they stayed indoors on days with high air pollution. Looking at whether the child spent time outdoors on any day, children with more severe asthma are less likely to have spent time outdoors. Families with more children aged 2 to 12 are more likely to spend time outdoors. Finally, children who parents own their house are more likely to spend time totally outdoors.

The surveys and research projects described above provide resources for the design of N-SAS, but none provide a detailed picture of risk perceptions, reported behavior and AQI awareness along with actual behavior (as reported in activity diaries) proposed for N-SAS. In addition, several of the studies are out of date or were collected from small samples.

A5. Impact on Small Businesses or Other Small Entities

This section is not applicable for our survey, since it will not involve or be administered to small businesses, governments, or organizations.

A6. Consequences of Collecting the Information Less Frequently

N-SAS consists of a total of nine surveys. All the surveys will be administered over a three to four month period. Based on previous activity diaries and sample size calculations, it is estimated that as many as seven activity diaries may be needed to obtain the desired level of precision in the estimates of outdoor time because of day-to-day variation in activity patterns. To detect a 15 to 30 minute change in time outdoors on Code Red and non-Code Red days with 95% confidence level, we estimate that we need at least two of each type of day per respondent.

A7. Special Circumstances Relating to the Guidelines of 5 CFR 1320.5

As described in section A6, respondents will report information more often than quarterly, with all nine surveys occurring within three or four months. Summer is the ozone season, so the data need to be collected during the season. There are no other special circumstances that require the data collection to be conducted in a manner inconsistent with 5 CRF 1320.5 (d)(2).

A8. Comments in Response to the Federal Register Notice and Efforts to Consult Outside the Agency

Comments

In accordance with the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), EPA published a notice in the Federal Register on February 28, 2008, announcing that the proposed survey. A copy of the Federal Register notice is attached at the end of this document in Appendix A.

No comments were received from the public.

Consultations

The content of the N-SAS surveys was developed through extensive consultation with content experts from both inside and outside EPA. The specific wording of the questions was reviewed by various content and survey design specialists and pretested to make sure the questions were understood correctly and the design of the survey was not difficult for respondents to understand. Finally, Knowledge Networks reviewed the survey instruments for length and burden on their panel. They found that the length of the surveys was average to shorter than average compared to typical surveys administered to their panel.

Consultations with Individuals

Dr. Carol Mansfield at RTI International is assisting EPA in the planning, design and administration of N-SAS through work assignments under EPA agreement 8295440. Dr. Mansfield was the PI on a STAR grant entitled “Behavioral Reactions to Ozone Alerts: What Do They Tell Us About Willingness-to-Pay for Children=s Health?” (see above) that collected data on outdoor activities and AQI awareness among parents of young children. She also designed questions about awareness of the AQI for the 2000 Health and Aging Study conducted jointly by RTI and Knowledge Networks, which were summarized in a report to EPA (Mansfield and Corey 2003). Dr. Mansfield and her colleagues at RTI have drawn on their experience with these and other environmental public health surveys to provide EPA with guidance on N-SAS. Dr. Mansfield worked with experts in risk communication, survey design, survey administration, sample statistics, non-response analysis, exposure analysis at RTI for the project.
Dr. V. Kerry Smith (W. P. Carey Professor of Economics, Arizona State University) provided consultation in the fall of 2005 during the planning stage of the survey on the content and administration plan through EPA Contract Number 68-D-00-265 (to E.H. Pechan and Associates, Inc.).
Joan Rohlfs (Chief, Air Quality Planning, Department of Environmental Programs, Metropolitan Washington Council of Governments) attended a focus group in Washington, D.C., to provide consultation on the survey design and content.

Advisory Panel

An advisory panel consisting of EPA staff and individuals from outside EPA was created in the fall of 2006 to provide advice on the design of N-SAS. In addition to Dr. Mansfield, the group consists of three representatives from outside EPA. EPA staff represented OAR/OAQPS, NERL, NCEA, NCER, and NHEERL.

The group met five times to discuss all aspects of the survey including topics, questions, sample population, geographic coverage of the survey, and mode of administration. This group reviewed the survey instrument and survey administration plan in February 2008 and provided comments that were incorporated into the final design of N-SAS.

Focus Groups and Cognitive Interviews

Two focus groups and nine cognitive interviews were conducted to design and test the N-SAS instrument. The first focus group was held in Raleigh, North Carolina, with nine individuals. The purpose was to identify basic attitudes and awareness of air quality problems. The group was asked to discuss their perceptions of air quality, risk perceptions and possible strategies for mitigating the impacts of air pollution. The questions were organized around health behavior theory to assess perceptions of the overall magnitude of the health risk and the individual’s personal risk followed by strategies for reducing the risk and perceived effectiveness. In general, the group was not very worried about air pollution as a health risk to themselves, except for a mother with an asthmatic child. They were able to discuss emission reduction tactics individuals could undertake, but had given very little thought to reducing their own exposure to pollution. The results from this group were used to begin creating the survey instrument.

The second focus group was held in Bethesda, Maryland, with nine individuals. Unlike the first focus group, which involved a general discussion of air quality, the purpose of the focus group was to test reactions to sections of the draft survey instrument including a list of specific risks that might result from exposure to air quality, emission reduction activities and exposure reduction activities. The group was much more knowledgeable about air pollution than the first group. However, they also did not feel that they faced much personal risk from air pollution and were much more familiar with emission reduction activities than exposure reduction activities. The results from this group were used to refine the list of risks and activities, as well as design questions to elicit motivations for or barriers to action.

After the focus groups, the survey instrument was developed and reviewed by RTI and EPA staff including survey methodologists and a specialist in health behavior and risk communication. The instrument was tested on nine individuals using cognitive interviews (five from Raleigh, North Carolina, and four from Atlanta, Georgia). The interviews were conducted by survey methodologists at RTI. The interviews tested the wording of the questions and the flow of the instrument. The feedback from the first seven interviews was used to revise the instrument prior to the final two interviews.

Presentations

2008 National Air Quality Conferences, April 6-9, 2008: Presented the design, sample, and questions for the N-SAS to an audience of EPA staff, local and regional air quality regulators, and others (contractors, researchers). Conference participants provided feedback and several local air quality staff expressed interest in participating.

EPA’s Workshop on Environmental Behavior and Decision-Making, February 13-14, 2008: Presented on the design, sample, and questions for N-SAS to academic researchers and EPA staff interested in evaluating voluntary programs and information-based programs. Conference participants provided feedback and suggestions for questions.

Peer Review

The draft survey instrument was peer reviewed by two academic experts, Dr. Mathew Neidell (Mailman School of Public Health, Columbia University) and Dr. Debbie Bennett (U. of California, Davis). The peer reviewers were asked to provide written comments on the topics included in the survey, the question wording, the proposed sample (age 35 and over), and the administration method (Knowledge Networks’ web panel). The comments from these reviewers included specific comments on the questions included and the wording of the questions, as well as questions about the choice of days for the activity diaries. The comments were incorporated into the final design of N-SAS.

Peer Review of Final Report

A final report summarizing the results from the data collection will be peer reviewed by three outside experts in fields such as economics, public health, risk communication, or risk/exposure analysis.
Publication plans: EPA intends to publish the results from the survey in peer-reviewed journals.

A9. Explanation of Any Payment or Gift to Respondents

Upon agreeing to be a Knowledge Networks panel member, Knowledge Networks respondents are given free hardware, free Web access, free e-mail accounts for each panel member, and ongoing technical support. While these products/services are provided to facilitate the data collection methodology, respondents are given free usage of the products for personal use, and these benefits are also used as an incentive for recruiting potential panel members.

N-SAS research participants in the study will be offered a small cash incentive to complete all the activity diaries and the debriefing survey. The total amount for completing all nine surveys will be $36. The honorarium is intended to recognize the time burden placed on the participants, encourage their cooperation, and to convey appreciation for contributing to this important study. Numerous empirical studies have shown that honoraria can significantly increase response rates (e.g., Abreu & Winters, 1999; Shettle & Mooney, 1999). The decision to use honoraria for this study is based on findings reported in current research publications and several projects conducted by Knowledge Networks and RTI, which found that use of an honorarium increases response rates among adults.

A10. Confidentiality

Knowledge Networks maintains the web panel from which the sample will be recruited. Appendix B contains a description of Knowledge Network’s security. Identifying information including names, address, and other personal information about the panel members will not be included in the data released to EPA staff or staff from RTI International, the contractor coordinating the survey and analysis. The RTI’s Institutional Review Board (IRB) reviewed all instruments, informed consent materials, and procedures to ensure that the rights of individuals participating in the study are safeguarded. RTI maintains restricted access to all data. All data files on multi-user systems will be under the control of a database manager, with access limited to project staff on a “need-to-know” basis only. Knowledge Networks has developed a secure transmission and collection protocol, including the use of system passwords and two separate sets of firewalls to prevent unauthorized access to the system. Neither questionnaires nor survey/screener responses are stored onto the WebTV box installed in Knowledge Networks respondents’ homes; questionnaires are administered dynamically over the Internet. Survey and screener responses are written in real-time directly to Knowledge Networks’ server and are then stored in a local Oracle database. The database is protected primarily through firewall restrictions, password protection, and 128-bit encryption technology. Individual identifying information will be maintained separately from completed screeners and questionnaires and from computerized data files used for analysis. Data on ineligibles will be destroyed. No respondent identifiers will be contained in reports, and results will only present data in aggregate.

A11. Justification for Sensitive Questions

No sensitive questions pertaining to private or personal information, such as sexual behavior or religious beliefs, will be asked in the survey.

A12. Estimates of Annualized Burden Hours and Costs

Respondent burden is presented in Table A1. We anticipate that email invitations will be sent to approximately 3,266 Knowledge Network panel members who meet the age and city requirements for N-SAS based on profile data Knowledge Networks maintains on panel members. Based on previous studies, Knowledge Networks estimates that 30% of the emails will not be opened (or 980 people will not open the survey invitation). 2,286 panel members are expected to open the email and take the screener.

The screening question on activity in the last month used in the screening survey comes from the BRFSS, and based on the results from the BRFSS, 30% of adults in the targeted age groups will not qualify for N-SAS (or 686 people out of 2,286). We estimate it will take 0.05 hours (or 3 minutes) to take the screener. The remaining 1,600 panel members who qualify for the study will take the screener and the baseline survey, which we estimate will take 0.25 hours (or 15 minutes) altogether.

We estimate that 60% of the 1,600 research participants (or 960 people) will complete each activity diary. The activity diaries are estimated to take 0.25 hours (or 15 minutes) to complete. The response rate among the sample taking N-SAS is expected to be lower for the activity diaries than normal Knowledge Networks surveys because the activity diaries will only be in the field for approximately 56 hours (8 hours the day the invitation is sent and 48 hours afterwards).

Finally, we estimate that 70% of the 1,600 research participants will complete the debriefing survey. We expect the debriefing survey will take approximately 0.33 hours (or 20 minutes) to complete.

In total, we expect 1,600 respondents to complete 10,126 surveys total for a total burden of 2,484 hours (0.26 hours per survey per respondent or 1.6 hours per respondent for all surveys completed).

Estimating Respondent Cost

Based on an average hourly wage of $27.54 (including employer costs of all employee benefits)^¹ and the burden hours described above, the survey authors expect that the total respondent cost $68,409 (or $6.76 per response for 10,126 responses).

A13. Estimates of Other Total Annual Cost Burden to Respondents and Record Keepers

Estimating Labor Costs

The proposed survey is of individuals in households, so the respondent burden will not entail any labor costs for employers.

Estimating Capital and Operations and Maintenance Costs

The proposed survey will not entail any capital or O&M costs.

Capital/Start-up vs. Operating and Maintenance (O&M) Costs

The proposed survey will not entail any capital or O&M costs.

Annualizing Capital Costs

The proposed survey will not entail any capital costs.

A14. ESTIMATING AGENCY BURDEN AND COST

EPA will hire a contractor to administer the N-SAS surveys and to assist in the analysis, summary, and dissemination of the survey data. In addition, EPA estimates that, from its own personnel, it will use two senior scientists for a total of 200 hours to oversee the survey administration and conduct analysis at a cost of $10,000 (based on an average annual salary of $100,000). Approximations of the expected costs to the Agency of these activities are summarized in Table A2.

Table A2. Estimated Agency Cost

Survey Component			Total Burden
	EPA Agency Labor
	Survey Administration	20 hours	$1,000
	Data Analysis	140 hours	$7,000
	Summary Report	40 hours	$2,000
	Contractor Support
	Survey administration		$265,000
	Survey management		$20,000
	Summary report		$15,000
	Total		$310,000

A15. Explanation for Program Changes or Adjustments

This neither a renewal nor a modification of an existing ICR; therefore, this section is not applicable for this ICR.

A16. Plans for Tabulation and Publication and Project Time Schedule

To measure and understand awareness, knowledge and behavior change related to the AQI, analysis will be guided by the predictions from health risk behavior theory and from the results from past studies. Figure 1 displays the relationship between an individual’s perceptions and the likelihood that the individual adopts health-promoting behaviors as modeled in health risk behavior theory. The likelihood that an individual changes their behavior depends on the individual’s (1) perception of the overall magnitude of the risk, (2) perception of their own vulnerability to the risk, (3) knowledge of risk averting behaviors, and (4) assessment of the self-efficacy of the averting behaviors (are the behaviors effective, can the individual actually adopt the behavior).

We hypothesize that an individual’s assessment of the overall magnitude of the risks posed by air pollution will depend on variables such as their knowledge of air pollution, demographic characteristics (including education, age, gender, race, income), attitudes toward the environment and the level of air pollution in the city where they live. Their own vulnerability to

Figure 1. Factors that Influence the Adoption of Health Behaviors

Perceived overall magnitude of risk

Perceived personal vulnerability

Risk-reduction options known to the individual

Perceived self-efficacy of known risk-reduction actions

Personal risk perception

Set of possible actions

Behavioral change observed

air pollution is hypothesized to be a factor of their health status, activity patterns, as well as knowledge, demographic characteristics, attitudes, and surroundings.

An individual’s knowledge of the actions one might take to reduce health risks is hypothesized to be a function of knowledge of the AQI or some other sources of information on air pollution such as their doctor, health status, and demographic characteristics. Finally, the individual’s decision about what, if any, action to take will depend on whether the individual considers the action effective and whether the individual has the flexibility in their schedule or budget to carry out the action. In addition to the individual’s appraisal of the action’s effectiveness, demographic characteristics, health status, employment conditions, commuting options and neighborhood characteristics are hypothesized to affect the final decision to take action.

Modeling behavior change in response to an AQI alert using the data from the activity diaries also requires data to control for other factors that affect the amount of time an individual spends outside and the flexibility of their schedule. If these factors are associated with activity patterns, then failure to control for them may bias the estimated coefficients or test statistics and/or reduce the efficiency of the estimates (inflate the standard errors). Important factors include

neighborhood characteristics
employment status and job characteristics
health
demographic characteristics such as age, gender, income
household composition and care-giving responsibilities
and climate variables such as temperature, humidity, precipitation, ozone level and other pollutant levels

The choice of variables included in N-SAS reflects the trade-off between research participant burden and the utility of the information. Table A3 lists the questions in the surveys (screening, baseline, activity diary and debriefing) and the reason the questions were included.

Q. 36-37 (questions about pollution in city)	Measure knowledge of pollutants in city and AQI forecast

A number of the questions used in N-SAS have been used in other surveys, and so the wording of these questions has been tested and validated. Appendix A lists the questions have been taken from other surveys. In most cases we used the exact wording of the question to take advantage of the survey instrument testing that has already been conducted for the other survey, although in some cases we modified the response categories or wording of the question to fit the mode of administration and flow of N-SAS instruments.

Analysis of the N-SAS data will consist of several parts. An initial report on the surveys will be produced when the data have been collected. The analyses for the survey report will consist of descriptive statistics (frequencies, crosstabs, t-tests, and Chi-squares) to examine the characteristics of the research participants, explore the potential for inferential analyses, and test for potential between-group differences. After this basic analysis, the data from the baseline, activity diaries and debriefing surveys will be used to assess hypotheses about differences in awareness, knowledge and actual behavior within the N-SAS sample.

Table A4 lists the primary measures that will be estimated, the basic data needed for the estimation and the analysis approach.

Table A4. Measures, Data and Analysis for N-SAS

Measure	Data	General Analysis Approach
Accountability
Extent of awareness of the AQI	Debriefing survey, questions asking name of AQI warning system, familiarity with systems	Calculate means, medians, range
Extent of knowledge about air pollution, actions to reduce exposure and emissions, health impacts	Debriefing survey, questions about air pollution in their city, actions people can take, health impacts	Calculate means, medians, range
Difference in awareness and knowledge across sub-groups of the research participants	Baseline data on the characteristics of the research participants and debriefing questions on awareness and knowledge	Statistically significant differences in means between sub-groups of the research participants
Behavior change -- Reduction in time outdoors on high ozone days (or time outdoors during peak ozone hours)	Activity diaries - total time outdoors (or outdoors during peak ozone hours) in minutes for each day, high ozone day indicator variable (versus low), weather, individual and city variables	Random effects panel regression, test for significant negative coefficient on “high ozone day” variable indicating total time outdoors lower on high ozone days, controlling for other factors
Behavior change – Reduction in exertion level during the day (or during peak ozone hours)	Activity diaries – exertion level for outdoor activities, minutes of outdoor time at each exertion level, high ozone day indicator variable (versus low), weather, individual and city variables	Create a continuous variable by converting exertion categories into average “mets”, use a random effects panel regression, test for significant negative coefficient on “high ozone day” Create an exertion-weighted time outdoors and estimate model to test for significant effect of “high ozone day” variable on exertion-weighted time outdoors
Behavior change – Reduction in time spent driving a personal car on high ozone days (or during peak ozone hours)	Activity diaries – Total time driving personal vehicle in minutes, high ozone day indicator variable, weather, individual and city variables	Random effects panel regression, test for significant negative coefficient on “high ozone day” variable indicating total time in car lower on high ozone days, controlling for other factors
Differences in behavior change across sub-groups of the research participants	Activity diaries, baseline and debriefing surveys.	Test the significance of coefficients in the random effects panel regressions for differences across sub-groups in behavior.
Exposure Modeling

Network Summary

WAN

Knowledge Networks’ Wide Area network (WAN) is setup as a fully-meshed cloud, which means that any site can directly connect to any other site without additional routing or single points of failure. Each office location is designed to automatically fail over to a secondary Internet connection if there is any disruption of service with the primary WAN. In practice, this has given us close to 100% uptime. See appendix 1a for Knowledge Networks’ WAN diagram.

Co-location Facility

Most of Knowledge Networks’ critical services, including all of the servers used for online surveys, are hosted at a physically secured co-location facility in the San Francisco Bay area. This facility incorporates the latest physical security through biometric readers and mobile cameras to ensure that physical access is restricted to authorized personnel only. In addition, this facility maintains N+2 redundant power through diesel power generators and UPS systems. The LAN at the facility is setup with redundancy wherever possible. The edge of our network is protected by fully redundant, clustered Cisco firewalls. These firewalls protect against incoming access from the Internet and help to ensure that only authorized connections to our web servers are allowed. The rest of the LAN is segmented into, secured Virtual LANs (VLANs) to separate out the different tiers of our services. These VLANs host connections to over 50 servers, including a completely load-balanced online survey system, a fully redundant Network Appliance storage system, and a fully redundant IBM Bladecenter. See appendix 1b for Knowledge Networks’ co-location facility diagram.

Survey Data Information Life-cycle

Data Collection

Survey data is collected by a web-based survey system that we internally refer to as “Dimensions”. This application runs on top of a secured Windows environment that has been hardened through various network and hosted-based security techniques. Our panelists take online surveys by using a web-browser to access a unique, secured web URL that is both emailed to them and made available through a secured web-portal. The URL provides access to click through to a highly-available load-balanced farm of web servers that hosts the online survey. This survey URL can be exposed via either standard http or over SSL and TLS encrypted https, depending on the client requirements. KN employs HTTP as the default; however, SSL is available upon request from the client. Throughout the interview process, questionnaire data is copied to a secured, centralized database for data processing.

Data Processing

Survey data is extracted from Dimensions through a secured, internal web-portal. While it is being cleaned up and analyzed, it is typically stored on secured file servers, local workstations, and email within our internal network. In all cases, access to these storage locations is restricted to authorized access by specific groups and individuals through role-based security.

Data delivery

While data can be delivered by a variety of different means, our default method is to send an unencrypted file as an attachment via email. If required by the client, we can offer the following alternatives: in person delivery, delivery via CD-ROM, FTP download, password protected zip file, https web portal downloads.

Data Retention

In most cases client data is left in place on our primary storage systems until we reach physical space limits. At that time, data is archived to a secondary storage system with the same security restrictions in place. Survey data is also backed up on a nightly basis to a disk-based backup system. Nightly backups are maintained for up to 90 days before the data is purged and the space is reused. This system is restricted to authorized IT staff.

All the survey data are permanently archived. On a case by case basis, we can purge the survey data if a client requests this of us.

Security Policy

Identifiable versus Non-identifiable Data

Identifying and non-identifying data has been separated into two different databases, using a role-based security model. Internal research analyst access is solely restricted to survey data, with absolutely no access to identifying information, while our panel management team has access to identifying data but absolutely no access to survey data. If needed, survey data can be further restricted to individual research analysts so that analysts working on a specific client projects won’t have access to data from other client projects.

With the need to support various systems effectively, certain senior members of the IT and engineering team have access to both roles.

Role-based Security

Our role-based security is designed around the principle of least privilege. That is, our data is classified as being accessible to either members of an identifiable data role or a non-identifiable data role.

The following groups within the company have access to identifiable data:

Panel Management Team
Senior Software Engineering team
Senior IT Team

The following groups within the company have access to non-identifiable data (questionnaire data):

Research Analysts
Client Service team members
Scripting Teams
Statistics
Senior Engineering Team
Senior IT Team

Password Policy

Knowledge Networks’ panel member passwords are designed to be easy to remember but difficult to guess. With that in mind, secure access to our panel member web-portal is determined by someone entering the appropriate email address and password. Panel member passwords are stored in a secured state within our panel management database software.

Knowledge Networks’ internal password policies use the following guidelines:

Strong Passwords with at least three distinct types of special characters
Passwords with at least 7 characters in length
Password expirations after 90 days
History of over 20 passwords per user account (This means a user needs to cycle through 20 passwords before they are allowed to reuse an old one)
Password lockout after 4 failed attempts

Security Auditing

All of our critical servers and network devices are constantly monitoring for authorized and unauthorized access to data. This is recorded in log files and reviewed on a regular basis. In addition, as mentioned earlier, we employ the use of host based intrusion detection systems to check for hacking attempts and or unauthorized changes to our systems. If a security breach occurs, that compromises the confidentiality of our identifiable data, we will notify any client that require this information disclosure.

We also use a centrally managed anti-virus solution from McAfee Inc., to proactively manage all of the Windows computers on our network, ranging from file servers to laptops. This helps us to ensure that data isn’t being secretly siphoned off to some unknown source on the Internet.

Monitoring

Our centralized monitoring system, Ipswitch’s Whatsup, checks services every minute. We use SNMP and http content scans to monitor all necessary services, systems and applications. We automatically receive service failure notifications through email and SMS on our cell phones.

Baseline Survey

The next set of questions asks about your outdoor activities yesterday. We know it can be hard to remember, but please try to answer as accurately as you can.

Thinking about yesterday, did you spend any time outside between the time you woke up and 12:00 noon? Please only include times when you were outside for at least 10 minutes continuously. Do not include time spent in your car or other vehicle.

[if Don’t know] Okay, let’s start when you woke up; think carefully about each activity you did after you woke up and before noon. Did you do anything outside for at least 10 minutes?

How much time did you spend outside? Please provide your best estimate.

Now I want to ask you about your activities when you were outside. During this time, did you engage in moderate or vigorous physical activity? Moderate activities cause only light sweating or a slight to moderate increase in breathing or heart rate. Some examples are brisk walking, bicycling for pleasure, golf, or dancing. Vigorous activities cause heavy sweating or large increases in breathing or heart rate.

Now let’s move on. Did you spend any time outside between 12:00 noon and 4:00 pm in the afternoon? Again, please only include times when you were outside for at least 10 minutes continuously and do not include time spent in your car or other vehicle.

Yes[skip to Q7]

How much time did you spend outside? Please provide your best estimate.

During this time, did you engage in any moderate or vigorous physical activity? Remember, Moderate activities cause only light sweating or a slight to moderate increase in breathing or heart rate. Some examples are brisk walking, bicycling for pleasure, golf, or dancing. Vigorous activities cause heavy sweating or large increases in breathing or heart rate.

Now, please think about the end of the day. Did you spend any time outside after 4:00 pm? Again, please only include times when you were outside for at least 10 minutes continuously and do not include time spent in your car or other vehicle.

I always know why I like things.

Thank you for completing the survey. This survey is part of a research project on daily activities. You have been selected to participate in the next step in the research project. To collect more information about individuals’ activities, we will be sending you a set of activity diaries. An activity diary is a survey that asks you questions about what you did during the day. The data from these diaries will be used to provide a better understanding of how people spend their day. The data collected from these diaries will be kept confidential – as always, your name will never be associated with the information from the surveys you take.

We will be sending you a total of 7 activity diaries this summer. First, we will ask you to fill out diaries for 4 days in a row and then later in the summer you will fill out diaries for another 3 days in a row. To alert you that a diary will be coming, you will receive an email 2 days before we send the first diary. We designed the diaries so that they will be easy to fill out, so the diary surveys shouldn’t take more than about 10 minutes to complete.

Your participation in this survey is very important for the overall success of the research project. You are part of a group of 1,600 people who will be completing activity diaries, and for our sample to be representative we need everyone to participate.

To thank you for your participation, you will receive a $36 bonus for completing all the surveys in this project.
