This paper presents the 1-year outcomes evaluation of Project Towards No Drug Abuse (Project TND), a large-scale indicated drug abuse prevention program in southern California applied to continuation high school youth, who are at high risk for drug abuse.

The efficacy of a nine-lesson health motivation-social skills-decision-making curriculum was evaluated in a three-condition experimental design. Twenty-one schools were randomly assigned by block to one of three conditions—standard care (control), classroom program, and classroom program plus a semester-long school-as-community component. A pretest was followed by a 3-week-long drug abuse prevention program and then a posttest at 14 continuation high schools. The 7 standard care schools received only the pretest followed by the posttest (same time duration). Subjects were followed up 1 year later.

Changes in use of cigarettes, alcohol, marijuana, and hard drugs were assessed in a pretest-1-year follow-up time interval. The follow-up rate was 67% (analysisn= 1,074). Indicated preventive effects were found on alcohol and hard drug use. No differences were found across the two program conditions.

Project TND is the first program to demonstrate 1-year self-reported behavioral effects on alcohol use and hard drug use among older, high-risk youth by using a school-based, limited-session model.
