ABSTRACT
Multiple group psychotherapy was employed as the primary treatment modality in a day-treatment program as an innovative multifaceted approach to treating adolescents comorbid for psychiatric and substance abuse diagnoses. The concurrent educational program included a high school on site. The groups included Substance Abuse Group, which promoted the 12-step model; Health Group; Psychotherapy Group; Leisure Time Group; Self-Awareness Group; and Multiple Family Group. The effect of the multiple groups was to provide a variety of experiences focusing on varied aspects of normal and dysfunctional adolescent development. Together the combination of groups served to strengthen the participants' cohesiveness, communicating skills, and hopefulness.
