Troubled-Desire & Therapeutic Chat for Reduction of CSAM Use (TD-CHAT)

Germany, Spain180 participantsStarted 2025-04-01

Plain-language summary

The goal of this prospective multicentred, stratified, parallel-group superiority study is to prevent and reduce the usage of Child Sexual Abuse Material (CSAM) by a Therapist Chat Service (TCS) and Selfhelp Platform for Self-Referred Patients, mostly men with a sexual interest in children. The interventions are based on Cognitive Behavioral Therapy (CBT) principles and designed to treat the sexual behavioral disorder related with CSAM consumption. 1. Participants in the Selfhelp modules group will show a statistically significantly higher proportion of reduction in CSAM behaviours four weeks after baseline, as compared to participants in the waitlist control group. 2. Participants in the Selfhelp modules followed by TCS group will show a statistically significantly higher reduction of CSAM behaviours compared to participants in the Selfhelp-only and TCS-only groups, post-intervention. Researchers will compare TCS-only-, Selfhelp-only-, Selfhelp + TCS- and Waiting group to see if if the interventions decrease CSAM use and improve mental well-being. Participants will get web based selfhelp-modules and/or text-based chat intervention operated by trained therapists.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
