Psychiatric comorbidity in compulsive sexual behavior disorder (CSBD)

Abstract

Compulsive Sexual Behavior Disorder (CSBD) is characterized by a persistent failure to control intense and recurrent sexual impulses, urges, and/or thoughts, resulting in repetitive sexual behavior that causes a marked impairment in important areas of functioning. Data collected from clinical populations suggest that CSBD frequently co-occurs with other Axis I and II psychiatric disorders; however, studies conducted so far suffer from methodological shortcomings that prevent the determination of accurate psychiatric comorbidity rates (e.g., small sample sizes, reliance on non-reliable assessment methods in the estimation of comorbidity or the non-inclusion of healthy individuals to compare prevalence rates). The purpose of this study was to explore psychiatric comorbidity in a sample of individuals with and without CSBD. The study sample comprised 383 participants distributed into two groups through a cluster analyses: 315 participants without CSBD (non-CSBD) and 68 qualifying as sexually compulsives (CSBD). Participants were assessed for co-occurring Axis I and II clinical conditions using structured clinical interviews for the DSM-IV (SCID-I and II). The majority of CSBD participants (91.2%) met the criteria for at least one Axis I disorder, compared to 66% in non-CSBD participants. CSBD participants were more likely to report an increased prevalence of alcohol dependence (16.2%), alcohol abuse (44%), major depressive disorder (39.7%), bulimia nervosa (5.9%), adjustment disorders (20.6%), and other substances -mainly cannabis and cocaine- abuse or dependence (22.1%). Concerning Axis II, prevalence of borderline personality disorder was significantly higher in CSBD participants (5.9%). As expected, prevalence of different psychiatric conditions was significantly increased among sexually compulsive participants, revealing comorbidity patterns with important implications in the conceptualization, assessment, and treatment of patients with CSBD.
