The purpose of this study was to assess the prevalence of specific psychiat
ric disorders in adolescents who have sexually molested other children. Twe
nty-two adolescent males (aged 13 to 17 years) who sexually molested a chil
d at least once were evaluated with structured clinical interviews for DSM-
III-R axis I disorders. All subjects met lifetime DSM-III-R criteria for pe
dophilia (with the exception of the age requirement), 21 (95%) for two or m
ore paraphilias, 18 (82%) for a mood disorder (12 [55%] for a bipolar disor
der), 12 (55%) for an anxiety disorder, 11 (50%) for a substance use disord
er, and 12 (55%) for an impulse-control disorder. Also, 12 (71%) of 17 subj
ects were diagnosed with attention-deficit/hyperactivity disorder, and 16 (
94%) with conduct disorder. We conclude that some adolescent child molester
s may have pedophilia or other paraphilias. Other axis I disorders with imp
ulsive features, especially conduct, attention-deficit/hyperactivity, bipol
ar, and substance use disorders, may also be found in these adolescents. Co
