Local and state school-based substance use surveys. Availability, content, and quality

School-based substance use surveys are an important data source for prevention and evaluation researchers, but access to students has become progressively restricted by schools. Because almost all states and many districts conduct their own regular surveys, archived data are a potential resource for informed policy and practice decisions. In this study, substance use survey data were successfully collected from 69 of 105 targeted school districts located in 12 states. Results indicate the availability and quality of extant data currently limit their usefulness. Recommendations are made regarding how schools could be assisted to improve the value of their substance use surveys.
