What this trial studies

This study aims to prevent and reduce the consumption of Child Sexual Abuse Material (CSAM) through a combination of a Therapist Chat Service (TCS) and self-help modules based on Cognitive Behavioral Therapy (CBT) principles. Participants will be divided into groups receiving different interventions, including TCS only, self-help only, and a combination of both, with a waitlist control group for comparison. The effectiveness of these interventions will be evaluated based on reductions in CSAM behaviors and improvements in mental well-being over a four-week period. The study seeks to provide insights into the best approaches for addressing sexual behavioral disorders related to CSAM consumption.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce CSAM consumption and improve mental health outcomes for individuals at risk.

How similar studies have gone: While the approach is innovative, similar interventions targeting behavioral change in sexual behavior have shown promise, though this specific combination is relatively novel.
