SummaryThis study extends the research base regarding PEERS intervention and suggests that the benefits of PEERS extend beyond the adolescent to the entire family system. Data also suggest that parents benefit from PEERS through increased confidence in their own parenting abilities.Acknowledgments This research was part of a doctoral dissertation and was supported by grants from the Organization for Autism Research (OAR) as well as the Marquette University Forward Thinking Program. Collaboration and guidance for implementation of PEERS was provided by Dr. Elizabeth Laugeson at the University of California, Los Angeles.
