The development and implementation of a model rehabilitative program is described in this dissertation. The conceptual model was developed to identify and characterize behavior patterns which interfere with learning in urban junior high schools. The six major behavior categories addressed include: dependent behavior, truancy, aggressive behavior, delinquent behavior, unstable behavior, and drug related behavior. The rehabilitative program was implemented by the staff of the Bayard Middle School in Wilmington, Delaware, during the 1976-77 school year. The Adaptive Behavior Scale, a self appraisal inventory, and a criterion test of basic skills were used to determine the effects of the program upon participants in each category. A detailed evaluation of program results, including statistical data on the program's effects upon serious incidents, student suspension rate, court referrals, student arrests, and vandalism, is presented. Samples of record keeping forms are also provided. (Author/GC)
