One-year follow-up effects of an acceptance-based treatment for hypersexuality

Hypersexuality is associated with significant psychological distress and health risks, yet few studies have examined the long-term effects of psychological interventions.

This study aimed to evaluate the one-year follow-up outcomes of a brief, individual Acceptance and Commitment Therapy (ACT) intervention for patients with clinically significant hypersexuality.

Ten participants who completed an eight-session ACT protocol were assessed at pre-treatment, post-treatment, and at 3-month and 1-year follow-ups using standardized self-report measures. Statistical and clinical significance were analyzed using repeated measures ANOVA, Friedman tests, and the Jacobson and Truax method to evaluate individual-level change.

Reductions in hypersexuality and craving interference, as well as increases in values-consistent behavior and perceived control over craving, were maintained at the one-year follow-up. Psychological inflexibility, which had not significantly changed immediately after treatment, showed significant improvement at 1-year follow-up. Clinically significant reductions in hypersexuality were observed in 9 out of 10 participants, while changes in psychological inflexibility were more limited.

These findings provide preliminary evidence for the sustained effectiveness, feasibility, and acceptability of a brief ACT-based intervention for hypersexuality, particularly among men with non-heterosexual orientations and individuals engaging in chemsex. Further controlled trials are warranted to confirm these results.
