Evaluation of multisystemic therapy pilot services in Services for Teens Engaging in Problem Sexual Behaviour...

Area of Science:

• Adolescent Psychology
• Clinical Psychology
• Forensic Psychology

Background:

• Problematic sexual behaviour in adolescents presents significant psychosocial challenges and community stigma.
• Multisystemic therapy (MST) shows promise in reducing adolescent sexual reoffending.
• There is an urgent need for effective and cost-effective management strategies for this population.

Purpose of the Study:

• To describe the protocol for the Services for Teens Engaging in Problem Sexual Behaviour (STEPS-B) feasibility trial.
• To assess the feasibility of implementing MST for problem sexual behaviour (MST-PSB) in antisocial adolescents at high risk of out-of-home placement.
• To gather data informing potential future large-scale trials and policy decisions.

Main Methods:

• A randomized controlled trial (RCT) involving 80 adolescents and their families across five London boroughs.
• Participants randomized to MST-PSB or management as usual, with follow-up to 20 months.
• Data collection includes official records, national databases, and participant/parent interviews and self-report measures.

Main Results:

• Primary outcome: out-of-home placement at 20 months.
• Secondary outcomes: sexual/non-sexual offending rates, antisocial behaviours, well-being, educational outcomes, and costs.
• Feasibility outcomes: clinical pathway mapping, RCT acceptability, and protocol acceptability.

Conclusions:

• The STEPS-B trial aims to inform policymakers and practitioners on the potential implementation of MST-PSB.
• Findings will guide necessary steps for full-scale implementation and future trials.
• The study addresses the critical need for effective interventions for adolescents with problematic sexual behaviour.
