Attrition in Substance Abuse Prevention Research: A Meta-Analysis of 85 Longitudinally Followed Cohorts.
Hansen, William B.; And Others
Evaluation Review, v14 n6 p677-85 Dec 1990
A meta-analysis of school-based substance abuse prevention studies revealed that the mean proportion of subjects retained dropped from 81.4 percent at the three-month followup to 67.5 percent at the three-year followup. Researchers should interpret their results in light of these normative data and adopt second-effort strategies to reduce attrition. (TJH)
