This practicum took place in seven treatment programs that offer residential, day treatment, and therapeutic school services to children and adolescents with social, emotional, and/or behavioral problems. Each of these programs provides milieu therapy including group-centered treatment guided by professional child and youth care counselors. The programs use a group-centered treatment model known as Situational Decision Making, and this practicum aimed to increase the degree of group leader compliance with the model's procedures. Improvement was addressed by the development and utilization of a group observation rating scale. Groups were observed and procedural items were scored, resulting in a percentage score called the degree of compliance. The scored instruments were returned as feedback to group leaders intending to increase the degree of compliance with prescribed group leader procedures, and summary results were shared with program administrators and managers. Groups were observed a second time to determine any change in degree of compliance. Results of the practicum indicate that average group leader compliance levels were substantially increased, although some individual group leaders did not improve at the desired level. Administrators and managers became more accurately aware of the degree of compliance in their groups, and their confidence in their ability to evaluate the degree of compliance increased. Appendices include the telephone questionnaires and several versions of the rating scale for group-centered leadership training. (Contains 19 references.) (JDD)
