A DSM-IV Axis I Comorbidity Study
of Males (n = 120) With Paraphilias
and Paraphilia-Related Disorders
Martin P. Kafka
and John Hennen
One hundred and twenty consecutively evaluated outpatient males with paraphil-
ias (PAs; n = 88, including 60 sex offenders) and paraphilia-related disorders
(PRDs; n = 32) were systematically assessed for certain developmental vari-
ables and DSM-IV-deﬁned Axis I comorbidity. In comparison with the PRDs,
the PA group was statistically signiﬁcantly more likely to self-report a higher in-
cidence of physical (but not sexual) abuse, fewer years of completed education, a
higher prevalence of school-associated learning and behavioral problems, more
psychiatric/substance abuse hospitalizations, and increased employment-related
disability as well as more lifetime contact with the criminal justice system. In
both groups, the most prevalent Axis I disorders were mood disorders (71.6%),
especially early onset dysthymic disorder (55%) and major depression (39%).
Anxiety disorders (38.3%), especially social phobia (21.6%), and psychoactive
substance abuse (40.8%), especially alcohol abuse (30%), were reported as well.
Cocaine abuse was statistically signiﬁcantly associated with PA males (p = .03).
There was a statistically signiﬁcant correlation between the lifetime prevalence of
Axis Inonsexualdiagnosesand hypersexual diagnoses(PAs andPRDs). Thepreva-
lence of retrospectively diagnosed attention deﬁcit hyperactivity disorder (ADHD)
was 35.8%, the third most prevalent Axis I disorder. ADHD (p = .01), especially
ADHD-combined subtype (p = .009), was statistically signiﬁcantly associated
with PA status. ADHD was statistically signiﬁcantly associated with conduct dis-
order, and both of these Axis I disorders were associated with the propensity for
multiple PAs and a higher likelihood of incarceration. When the diagnosis of
ADHD was controlled, the differences reported above between PAs and PRDs
either became statistically nonsigniﬁcant or remained as only statistical trends.
