The problems of male adolescent sex offenders with intellectual disabilities were described and issues for treatment reviewed. A group treatment based on cognitive therapy was offered. Treatment methods and assessment of attitudes related to commission of sexual offenses were described. Four case studies of teenage male adolescent sex offenders with intellectual disabilities were presented. All subjects responded to treatment. Their individual differences related to their responses were discussed in the context of the type of denial exhibited by each subject. At the time of this study, 3 years had elapsed for 2 subjects and 4 years for the other 2 without a recurrence of an offense.
