Impulsivity in Compulsive Sexual Behavior Disorder and Pedophilic Disorder
Impulsivity in Compulsive Sexual Behavior Disorder and Pedophilic Disorder

Summary/Abstract: Background and aims: Impulsivity is regarded as a risk factor for sexual crime reoffending, and a suggested core feature in Compulsive Sexual Behavior Disorder. The aim of this study was to explore clinical (e.g. neurodevelopmental disorders), behavioral and neurocognitive dimensions of impulsivity in disorders of problematic sexuality, and the possible correlation between sexual compulsivity and impulsivity. Methods: Men with Compulsive Sexual Behavior Disorder (n 5 20), and Pedophilic Disorder (n 5 55), enrolled in two separate drug trials in a specialized Swedish sexual medicine outpatient clinic, as well as healthy male controls (n 5 57) were assessed with the Hypersexual Behavior Inventory (HBI) for sexual compulsivity, and with the Barratt Impulsiveness Scale (BIS) and Connors’ Continuous Performance Test-II (CPT-II) for impulsivity. Psychiatric comorbidity information was extracted from interviews and patient case files. Results: Approximately a quarter of the clinical groups had AttentionDeficit/Hyperactivity Disorder (ADHD) or Autism Spectrum Disorder. Both clinical groups reported more compulsive sexuality (r 5 0.73 0.75) and attentional impulsivity (r 5 0.36 0.38) than controls (P < 0.05). Based on results on univariate correlation analysis, BIS attentional score, ADHD, and Commissions T-score from CPT-II were entered in a multiple linear regression model, which accounted for 15% of the variance in HBI score (P < 0.0001). BIS attentional score was the only independent positive predictor of HBI (P 5 0.001). Discussion: Self-rated attentional impulsivity is an important associated factor of compulsive sexuality, even after controlling for ADHD. Psychiatric comorbidity and compulsive sexuality are common in Pedophilic Disorder. Conclusion: Neurodevelopmental disorders and attentional impulsivity – including suitable interventions – should be further investigated in both disorders
