This study examined the efficacy of a game-based cognitive-behavioral group therapy program for addressing problems typically found among elementary school-aged victims of child sexual abuse immediately after treatment and at three months following treatment. It was hypothesized that positive gains would be observed among the following domains: (a) internalizing symptoms (e.g., anxiety, depression, and trauma); (b) externalizing behaviors (e.g., oppositional behavior, disobedience, and conduct disordered behavior); and (c) sexually inappropriate behaviors. Improved knowledge of abuse and personal safety skills was also predicted. Results indicated that game-based cognitive-behavioral group therapy resulted in improvements in internalizing symptoms, externalizing behavioral problems, total behavioral problems, and personal safety skills both immediately after treatment and at three-month follow-up.
