Group treatment programs are a common intervention for children who have been sexually abused. However, empirical literature demonstrating their effectiveness, particularly among preadolescent males, is scarce. The authors evaluated the effectiveness of semistructured group work with six preadolescent boys who had experienced either extra- or intrafamilial sexual abuse. From pre- to postgroup, the boys experienced decreased anxiety, decreased depression, increased self-esteem, and decreased internalizing and externalizing behaviors. Further gains were generally observed from postgroup to follow-up. The success of the group-treatment program is attributed, in part, to the implementation of a reward program designed to reduce disruptive behavior.
