Proposed Data Collections Submitted for Public Comment and
Recommendations
In compliance with the requirement of Section 3506(c)(2)(A) of the
Paperwork Reduction Act of 1995 for opportunity for public comment on
proposed data collection projects, the Centers for Disease Control and
Prevention (CDC) will publish periodic summaries of proposed projects.
To request more information on the proposed projects or to obtain a
copy of the data collection plans and instruments, call 404-639-5960
and send comments to Seleda Perryman, CDC Assistant Reports Clearance
Officer, 1600 Clifton Road, MS-D74, Atlanta, GA 30333 or send an e-mail
to omb@cdc.gov.
Comments are invited on: (a) Whether the proposed collection of
information is necessary for the proper performance of the functions of
the agency, including whether the information shall have practical
utility; (b) the accuracy of the agency's estimate of the burden of the
proposed collection of information; (c)
[[Page 36346]]
ways to enhance the quality, utility, and clarity of the information to
be collected; and (d) ways to minimize the burden of the collection of
information on respondents, including through the use of automated
collection techniques or other forms of information technology. Written
comments should be received within 60 days of this notice.
Proposed Project
Experiment in Mapping Behavioral Risk Factors Surveillance Survey
(BRFSS) Data--NEW--National Center for Chronic Disease Prevention and
Health Promotion (NCCDPHP), Centers for Disease Control and Prevention
(CDC).
Background and Brief Description
The purpose of this study is to design and implement a Web-based
interview examining the differential effectiveness of presenting BRFSS
data in two different mapping formats, choropleth versus isopleth maps.
Traditionally, geospatial data are presented in choropleth maps, where
defined geographic units, such as county or state boundaries, are
filled with a uniform color or pattern. Choropleth maps present data as
geographic areas shaded with intensity proportional to the data values
associated with those areas. Such maps are appropriate for data that
have been scaled or normalized. Alternatively, geospatial data can be
displayed using isopleth maps, in which the data are not aggregated to
pre-defined geographic units, but instead are ``smoothed'' across
adjacent geographic boundaries. Such maps may show county or state
boundaries, but different categories of data are not defined by these
geographic units. Little empirical research has examined the
differential effectiveness of choropleth versus isopleth maps. In
particular, researchers know little about how the two different mapping
techniques affect the user's ability to extract information from the
map.
The Web-based interview will present both choropleth and isopleth
maps displaying BRFSS data in seven color categories. To maintain a low
survey burden for each participant, the instrument will include only 4
questions for each of 10 maps. The interview will also include
additional questions about respondent's preferences for map types and
background characteristics. The survey instrument will be comprised of
50 items, including the 40 map questions, 4 questions about users'
preferences for different map formats, and 6 questions about their
educational and professional background and demographic
characteristics. Analysis of the data will assess 4 key areas to
determine which type of map is ideal for presenting BRFSS data:
1. Rate retrieval
2. Pattern recognition
3. Ease of understanding
4. User preferences
The results of these analyses will be presented in a final report
to be submitted to the CDC. There are no costs to respondents other
than their time.
