Psychiatric Features of 36 Men Convicted of Sexual Offenses

Background: To increase understanding of the relationship between sexual violence and mental illness, the authors assessed the legal histories and psychiatric features of 36 males convicted of sexual offenses.

Method: Thirty-six consecutive male sex offenders admitted from prison, jail, or probation to a residential treatment facility received structured clinical interviews for DSM-IV Axis I and II disorders. The participants’ legal histories, histories of sexual and physical abuse, and family histories of psychiatric disorders were also assessed.

Results:The participants’ mean +/- SD age was 33 +/- 8 years. They had been convicted a mean of 1.8 +/- 1.4 times (range, 1-9 times) for sexual offenses and incarcerated a mean of 8 +/- 6 years (range, 0-22 years). Participants displayed high rates of lifetime DSM-IV Axis I disorders: 30 (83%) had a substance use disorder; 21 (58%), a paraphilia; 22 (61%), a mood disorder (13 [36%] with a bipolar disorder); 14 (39%), an impulse control disorder; 13 (36%), an anxiety disorder; and 6 (17%), an eating disorder. Participants also displayed high rates of Axis II disorders, with 26 (72%) meeting DSM-IV criteria for antisocial personality disorder. In addition, subjects reported experiencing high rates of sexual (but not physical) abuse and high rates of Axis I disorders, especially substance use and mood disorders, in their first-degree relatives. Compared with subjects without paraphilias, subjects with paraphilias displayed statistically significantly higher rates of mood, anxiety, and eating disorders, as well as significantly higher rates of childhood sexual abuse.

Conclusion: Recognition and treatment of major psychiatric disorders among sex offenders may increase chances for successful rehabilitation, reduce recidivism and public victimization, and produce significant public health and economic benefits. More studies in this area appear warranted to search for more effective interventions for this severe public health problem.
