This study examined the effects of music and group stage on group process and group leader and member behavior within 8-week psychoeducational groups for children of divorce. Audiotapes of group sessions were rated using the Interactional Process Analysis and the Group Sessions Ratings Scale. Both treatment groups were very similar in terms of group leader and member behavior. Significant differences were noted between time periods. Over time, group leaders were consistent in giving directions and suggestions and asking questions. During later sessions, there was more of a focus on problem solving, expression and exploration of feelings, roleplaying, and interpersonal learning. (Contains 4 figures and 2 tables.)
