Noreen McDonaldPI. Healthy People 2010 is a federal program that provides science-based, ten-year national objectives for improving the health of all Americans. For the past three decades, Healthy People has established benchmarks and monitored progress over time in order to encourage collaborations across sectors; guide individuals toward making informed health decisions; and measure the impact of prevention activities. The program specifically called for greater physical activity for children through increased walking and biking to school. To support this effort, Congress authorized $612 million for the Safe Routes to School program, but lack of evaluation of SRTS programs potentially threatens opportunities for continued program funding even though there is ample data collected on all federally-funded SRTS projects. The National Center for SRTS has received 150,000 parent surveys and 26,000 classroom surveys representing approximately 520,000 elementary and middle school students from schools across the country. Unfortunately most of this data was not systematically analyzed by researchers. One reason for the lack of analysis is that the validity and reliability of the National Center’s survey instruments were not established. The purpose of this study, funded by the Robert Wood Johnson Foundation, measured the reliability and validity of the SRTS parent and child surveys in various geographic and demographic settings. Establishing the reliability and validity of these instruments accelerated SRTS program evaluations and provided researchers with a consistent set of measures of children’s school travel. A secondary goal of the project identified ways to improve the current survey instruments. For more information contact Noreen McDonald at noreen@unc.edu.
