Study 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.

Eligibility

Primary outcome measure(s)

• Reduction in Child Sexual Abuse Material (RCSAM) severity — every 2 weeks for 12 weeks after onboarding
  A) Reduction in Child Sexual Abuse Material severity (RCSAM severity): A reduction in CSAM severity in the last 2 weeks, defined as the pre-post difference in highest "Combating Paedophile Information Networks in Europe" (COPINE) scale scores, with a reduction from severity levels 4 or higher to levels 3 or lower after the intervention.
• Reduction in Child Sexual Abuse Material (RCSAM) time — every 2 weeks for 12 weeks after onboarding
  B) Reduction in Child Sexual Abuse Material time (RCSAM time): A 50% or greater decrease in CSAM consumption time (minutes) over the past 2 weeks. CSAM time is measured as the time (in minutes) spent consuming CSAM materials over the past 2 weeks.
• Reduction in Child Sexual Abuse Material (RCSAM) risk — every 2 weeks for 12 weeks after onboarding
  C) Reduction in self-reported risk of Child Sexual Abuse Material use (RCSAM risk): A reduction in self-reported risk of CSAM use (RCSAM risk): A decrease in the risk of CSAM consumption over the last 2 weeks, defined as a pre-post decrease in self-reported risk, as measured using an adapted version of the "Sexual Child Molestation Risk Assessment" (SChiMRA+) Part A.
