Baseline Nonresponse in Project ALERT: Does It Matter?
Abstract
This Note evaluates the impact of baseline nonresponse in Project ALERT (Adolescent Experiences in Resistance Training), a longitudinal experiment that test the effectiveness of a school-based drug prevention program for seventh- and eighth-grade students in 20 treatment and 10 control schools in California and Oregon. Of the intended sample, 16 percent failed to participate in some or all of the baseline data collection. The main reasons were: parents' refusal to allow their children to participate in any data collection, students' refusal to participate in some or all of the data collection, and absenteeism from school on survey dates. Students who missed the baseline survey will be dropped from the main analysis of treatment effects in Project ALERT.
