What this Trial Is About

Researchers are evaluating behavioral interventions aimed at reducing the use of Child Sexual Abuse Material (CSAM) among self-referred participants, mostly men with a sexual interest in children. This prospective, multicenter study compares different web-based and text-based therapy approaches, focusing on Cognitive Behavioral Therapy (CBT) principles, to address sexual behavioral disorders related to CSAM consumption. The goal is to determine which interventions best reduce CSAM use and improve mental well-being. The study includes four groups: participants receiving only selfhelp modules, those receiving only Therapist Chat Service (TCS), participants using selfhelp modules followed by TCS, and a waitlist control group. Selfhelp modules consist of 16 web-based structured CBT sessions, while TCS involves 4-6 text-based chat sessions with trained therapists. The waitlist group receives no intervention for the first two weeks. Researchers will also compare data from an additional waitlist plus TCS group from a related project. Participants will be followed for 12 weeks after onboarding with assessments every two weeks to measure reductions in CSAM severity, time spent, and risk. Secondary measures include mental well-being, frequency of CSAM consumption, total sexual outlet, and any adverse psychological effects. Data will be collected through self-reports and questionnaires, and safety will be monitored throughout the study period.
