Four of five had served lengthy prison sentences (M, 7.8 years) for conviction of sexual crimes. All subjects had previous treatment in penitentiary or community-based sexual offender programs. Two had a history of major depression and two had a prior diagnosis of alcoholism. Two subjects reported bisexual pedophilic preference; two exclusively heterosexual preference; and one an exclusively homosexual preference. At baseline and throughout the study, all five subjects met the DSM-IV criteria for pedophilia, as well as antisocial personality disorder (American Psychiatric Association, 1994; Berger, Berner, Bolterauer, Gutierrez, & Berger, 1999).
