Project IMPACT is based on an innovative prevention/community intervention model designed to stem the use of drugs and alcohol in an Oregon school district. A total of 74 teachers, administrators, and community leaders participated in a training session which included didactic and experiential sessions informing participants about the nature and extent of substance abuse in their communities and teaching them substance abuse diagnostic and intervention skills. Etiology of substance-abusing behavior, communication skills training, and family systems concepts were all basic components of the IMPACT training. An evaluation of the training indicated that: (1) teachers who participated in IMPACT were significantly more confident in their substance abuse diagnostic skills and had a greater awareness of the drug problem than teachers who had not participated; (2) teachers in the IMPACT training group appeared to provide more alcohol and drug education to their students than did the control respondents; (3) based on a survey of parents, a significant association was found between having a child with a drug problem and their parents' preference for prosocial responses over punitive responses to cope with substance abuse problems; (4) parents and teenagers reporting very communicative families estimated less drug and alcohol use by children; and (5) teenagers' levels of drug and alcohol use was significantly related to peer use levels.
