This article reviews the available literature on group-based social skills interventions for adolescents with autism. Forty-four studies were identified that were published in peer-reviewed journals. While each identified treatment utilized a group format, there was significant heterogeneity among the implemented procedures and evaluative methods. Studies were compared on a number of dimensions, and trends in the field were identified. The findings suggest that there is significant evidence for the usefulness of social skills groups as an intervention for adolescents with autism, and the evidence base is rapidly growing. In addition to a summary of the existing literature, recommendations for areas of future research are identified.
