This paper describes an adventure-based treatment program for court-involved youth who display significant alcohol or drug abuse behavior. Project Choices' clients meet the criteria for drug abuse from the Diagnostic Statistical Manual-Revised (DSM-III-R). The clients reside in Project Choices placement homes during the 8-week treatment and 8-week transition programs. Beginning with a morning meditation along with individual and group goal setting, each treatment day includes various group sessions. Through the use of adventure activities, the group is guided sequentially from simple group and individual tasks to more creative and complex problem solving. In addition, the odd-numbered weeks are spent camping out with the fifth week spent in a wilderness environment. In the first four groups, 37 clients completed the 8-week treatment program, and 36 of the 37 clients completed the 8-week transitional aftercare program. Students were rated on weekly behavioral measures by counselors, peers, and themselves. Significant differences in ratings were found in all three groups, suggesting that changes in the client's behavior were noticeable to staff, peers, and self. Subjects' scores decreased from pretest to posttest on the depression and disorganized thinking scales of the Minnesota Multiphasic Personality Inventory (MMPI). Such a decrease was more significant on the Beck Depression Inventory. (KS)
