Abstract

A meta-analysis of substance abuse prevention studies revealed that the mean proportion of subjects retained dropped from 81.4% at 3-month to 67.5% at 3-year follow-ups. Time from pretest alone accounted for less than 5% of the variance. Other available predictors of retention were not significant. Researchers are encouraged to interpret their results in light of these normative data and to adopt second-effort strategies to reduce attrition.
