Testing the Effectiveness of Cognitive Analytic Therapy for Hypersexuality Disorder: An Intensive Time-Series Evaluation.

The evidence base for treatment of hypersexuality disorder (HD) has few studies with appropriate methodological rigour. This study therefore conducted a single case experiment of cognitive analytic therapy (CAT) for HD using an A/B with extended follow-up design. Cruising, pornography usage, masturbation frequency and associated cognitions and emotions were measured daily in a 231-day time series. Following a 3-week assessment baseline (A - 21 days), treatment was delivered via outpatient sessions (B - 147 days), with the follow-up period lasting 63 days. Results show that cruising and pornography usage extinguished. The total sexual outlet score no longer met caseness and the primary nomothetic hypersexuality outcome measure met recovery criteria. Reduced pornography consumption was mediated by reduced obsessionality and greater interpersonal connectivity. The utility of the CAT model for intimacy problems shows promise. Directions for future HD outcome research are also provided.
