Delivery of Children's Services and the Promotion of Children's Mental Health from the American Orthopsychiatric Association. His recent books include Adolescent Risk Behaviors: Why teens experiment and strategies to keep them safe (with P. Jaffe & C. Crooks; Yale University Press, 2006); Child abuse: Implications for child development and psychopathology, 2nd Edition (Sage, 1999); and Abnormal Child Psychology, 4th edition (with E. Mash; Wadsworth, 2009). Wolfe is a founding member of the Center for Research & Education on Violence Against Women and Children at the University of Western Ontario, where he and colleague Peter Jaffe coined the term "Children of Battered Women" and "Children Exposed to Domestic Violence", now used widely within the mental health and justice systems. He recently published an updated book in this area (with P.Jaffe and M. Campbell - Growing Up with Domestic Violence: Assessment, Intervention & Prevention Strategies for Children & Adolescents). His expertise in the field of child and adolescent psychology has led him to testify as an expert, in multiple cases; including the high-profile case of sexual abuse at Mount Cashel Orphan age in Newfoundland run by The Christian Brothers of Ireland in Canada. Wolfe also provided expert evidence into the Cornwall Public Inquiry into historical sexual abuse in that community. He is cited extensively by Judge Normand Glaude in the inquiry report as one of the leading experts in child sexual abuse. Studies and projects Wolfe's main interest lies in violence prevention among youth and families, based on his research with colleagues demonstrating the harmful impact of multiple forms of abuse on children, including exposure to domestic violence. Wolfe's interest in violence prevention has culminated into a comprehensive school-based initiative for reducing violence amongst adolescents and related risk behaviors, known as "The Fourth R: Skills for Youth Relationships." It has recently been identified as a top evidence-based program for school-based violence prevention by the New Jersey-based Robert Wood Johnson Foundation where it is being implemented in several US sites as a part of their Start Strong violence-prevention initiative An evaluation of "The Fourth R" program found that teaching youths about healthy relationships as part of their required health curriculum reduced physical dating violence and increased condom use 2.5 years later at a low per-student cost. A discussion of the program can be heard in a podcast interview conducted by the California Coalition Against Sexual Assault and Peace Talks radio The Public Health
