Studies included simple post-hoc comparisons across ASAP sites, 2 experimentally controlled studies, ASAP project-level evaluations, a quasi-experimental survival rate analysis, an 11-city experimental study, and a single-city large-scale experimental study. Early studies during the project suggested that some ASAP treatment modalities may have had a positive effect on recidivism. Large-scale quasi-experimental studies appeared to support positive treatment effects for social but not problem drinkers. The 11-city study found little or no effectiveness for either education or treatment programs. Preliminary results from a large-scale experimental study of first offenders found no significant differences in recidivism between social and problem drinkers as a result of education programs. Overall, results suggest that such programs have little effect in modifying the subsequent behavior of those exposed to them. 7 references, 4 tables, and 12 figures.
