Drug abuse prevention programs conducted during junior high school can produce meaningful and durable reductions in tobacco, alcohol, and marijuana use if they (1) teach a combination of social resistance skills and general life skills, (2) are properly implemented, and (3) include at least 2 years of booster sessions.

Students (N = 4,466) attending 56 schools in New York State were involved in a 3-year study testing the effectiveness of a cognitive-behavioral approach to substance abuse prevention. In a randomized block design, schools were assigned to receive (a) the prevention program with formal provider training and implementation feedback, (b) the prevention program with videotaped provider training and no feedback, or (c) no treatment. After pretest equivalence and comparability of conditions with respect to attrition were established, students who received at least 60% of the prevention program (N = 3,684) were included in analyses of program effectiveness. Significant prevention effects were found for cigarette smoking, marijuana use, and immoderate alcohol use. Prevention effects were also found for normative expectations and knowledge concerning substance use, interpersonal skills, and communication skills.

Two-year follow-up data (from inner-city, minority adolescents) were collected to test the effectiveness of 2 skills-based substance abuse prevention programs and were compared both with a control condition and with each other. Students were originally recruited from 6 New York City public schools while in 7th grade. Schools were matched and assigned to receive a generic skills training prevention approach, a culturally focused prevention approach, or an information-only control. Students in both prevention approaches had less current alcohol use and had lower intentions to engage in future alcohol use relative to students in the control group. Students in the culturally focused group also engaged less in current alcohol behavior and had lower intentions to drink beer or wine than those in the generic skills group. Both prevention programs influenced several mediating variables in a direction consistent with nondrug use, and these variables also mediated alcohol use.Recent national survey data (Johnston, O'Malley, & Bachman, 1994) showed that substance use is once again on the increase, further underscoring the importance of developing effective prevention approaches.
