Abstract

Objective: The purpose of this study was to compare the effects of a single drug, i.e., alcohol, against a multiple drug preventive intervention.

Methods: A controlled trial was conducted with 448 8th grade students (mean age = 13 years old) from an inner-city middle school (n = 216) and a rural junior high school (n = 232) in 2000-2001. Students were randomized within school, and 3-month post-intervention follow-up data were collected.

Results: Two risk/protective factors were found to differ significantly in favor of youth receiving the single drug alcohol intervention (p's = 0.03), while the frequency of alcohol use and two additional risk/protective factors approached significance (p's < 0.10).

Conclusion: These findings support the potential efficacy of a brief, single drug preventive intervention over a brief, multi-drug intervention in producing short-term alcohol outcomes for adolescents, and indicate differential effects of interventions for subgroups of substance using youth.
