Study subjects were assigned to one of three study groups to evaluate the effectiveness of the PS-AID coping skills training program in decreasing the likelihood of subsequent DWI arrests and potentially problematic drinking: the PS-AID skills training group (n = 203), the Alcohol Control Interview (ACI) which served as a minimal contact group (n = 174), or the No Contact Control Group (n = 180). The differences among the three groups failed to reach significance, yet the PS-AID group accumulated 20 to 30 percent fewer alcohol violations over the follow-up period than did the comparison groups which suggests that the program may offer substantial promise as a preventive intervention for DWI first offenders. The effectiveness of the intervention was moderated by a number of personal characteristics of the participants which suggests an interaction between client and treatment. The PS-AID group appeared to have a greater reduction in self-reported drinking behavior than those in the other groups. 3 figures, 6 tables, and 36 references (Author abstract modified)
