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.
Therefore, the EPA research team does not intend to generalize the
results of the N-SAS survey beyond the relevant population of the
Knowledge Networks panel.

        A2.	Purpose and Use of the Information Collection

Need/Authority for the Collection

  SEQ CHAPTER \h \r 1 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.

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 following individuals participated in
advisory group meetings

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) 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.

A15.  Explanation for Program Changes or Adjustments

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

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 

N-SAS includes urban/suburban/rural distinction

Information on research participant’s Census Block (provided by
Knowledge Networks) provides approximate measures of distance to city
center and major roadways, population density, dominant housing type,
lot size, and amount of open space nearby

employment status and job characteristics

N-SAS includes employment status, number of jobs and hours worked,
physical requirements of the job, and approximate time outdoors at job

health

N-SAS includes general health and specific respiratory and heart
conditions

demographic characteristics such as age, gender, income

N-SAS includes income, household size, language spoken at home

Knowledge Networks’ profile includes age, gender, race, education, and
marital status

household composition and care-giving responsibilities

and climate variables such as temperature, humidity, precipitation,
ozone level and other pollutant levels

Information on weather will be obtained from NOAA weather data and
information on ozone and PM will be obtained from EPA monitoring data

	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.

reported use of the warnings

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.

Network Summary

WAN 

Knowledge Networks’ Wide Area network (  HYPERLINK
"http://en.wikipedia.org/wiki/Wide_Area_Network"  WAN ) is setup as a  
HYPERLINK "http://en.wikipedia.org/wiki/Mesh_networks"  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.    HYPERLINK  \l
"_Appendix_1a:__Knowledge Networks’ W"  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   HYPERLINK
"http://en.wikipedia.org/wiki/Uninterruptible_Power_Supply"  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  HYPERLINK
"http://en.wikipedia.org/wiki/Firewall_%28networking%29" 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 ( 
HYPERLINK "http://en.wikipedia.org/wiki/VLAN"  VLANs   HYPERLINK
"http://en.wikipedia.org/wiki/VLAN"   ) 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.    HYPERLINK  \l "_Appendix_1b:__Co-location Facility " 
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   HYPERLINK
"http://en.wikipedia.org/wiki/Role-Based_Access_Control"  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,   HYPERLINK
"http://www.ipswitch.com/Products/WhatsUp/"  Ipswitch’s Whatsup ,
checks services every minute. We use   HYPERLINK
"http://en.wikipedia.org/wiki/SNMP"  SNMP  and http content scans to
monitor all necessary services, systems and applications. We
automatically receive service failure notifications through email and  
HYPERLINK "http://en.wikipedia.org/wiki/Short_message_service"  SMS  on
our cell phones.

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.
