This article reviews the current literature, specifically meta-analytic research, on the effectiveness of psychoeducational and counseling groups in the schools. Topics for such groups include: eating disorders, anger management/bullying, child sexual abuse prevention, pregnancy prevention, and social competency. There is support for groups in the schools, specifically some psychoeducational groups and classroom interventions. There is also support for the use of group interventions that are both short in session length and overall time. Research reflects the importance of adjusting content to the population and maturity level of group members as well. Future research should more clearly identify the type of group intervention and goals used as well as reflect collaborations between researchers and school counselors.
