The clients enrolling in the eight OBH programs during the period of this study were predominantly male (69%) and between the ages of 16-18 (75%). Clients entered treatment with a variety of disruptive behavioral, mood and substance disorders as their primary psychiatric diagnoses. Of the 481 clients for whom data were available on diagnoses, 48% also had a secondary diagnoses. Most prevalent were those diagnosed with behavioral disorders (38%), some form of substance abuse or dependence disorder (30%), and mood disorders (22%). Over half (57%) of the OBH clients had a history of outpatient treatment, 17 % had utilized inpatient services, and 13% had utilized both types of services prior to OBH treatment.

Client self-report mean Y-OQ scores were 70.67 at admission and 47.55 at discharge, indicating an average score reduction of more than 20 points. Parent assessment Y-OQ mean scores were 101.19 at admission and 48.55 at discharge, indicating an average reduction of 52.64. Thus, parents rated the clients presenting symptoms as more severe than did the clients themselves, but they perceived symptoms at discharge that were very similar. Discharge scores for both client self report and parent assessment are close to the normal range of symptoms (46 or below) as established by Burlingame et al. (1995b) in their sample tests of normal populations. Client self-reported Y-OQ scores across all ages show similar reductions from admission to discharge, and with exception of 15-year olds, showed a trend of increasing score reductions with increasing age (16 to 18). Parent assessments across all age groups were higher at admission and showed similar reductions at discharge. Female clients report higher Y-OQ admission and discharge scores for both client self-report and parent assessments, and also showed a greater reduction in scores than males. However, discharge scores for females remained higher than for males (54.37 and 47.44 respectively).
