Meta-Analysis of Adolescent Drug Prevention Programs: Results of the 1993 Meta-Analysis

Abstract

Policy relevant conclusions emerge when meta-analytic techniques are used to achieve consensus out of the inconsistencies found in individual research studies. Extensive search procedures located 120 school-based drug prevention programs that evaluated success on self-reported drug use measures. Hypothesis tests were made of an a priori classification scheme for the type of program. Six types of programs were identified based on content and delivery and were collapsed into noninteractive and interactive programs.
