Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are community-based young people aged 10–17 referred to FCAMHS for aggressive or violent behaviour who can consent or assent (with parent/carer involvement where required) and whose participation will not conflict with statutory orders.
✕Probably not a fit
Young people under 10 or 18 and older, those with imminent plans to move to hospital, residential or secure settings, or whose legal/orders would be disrupted by participation may not receive benefit or be eligible.

What this trial studies
The trial randomises young people referred to Forensic Child and Adolescent Mental Health Services (FCAMHS) in England to receive either mentalization-based therapy (MBT) alongside usual support or usual support alone. MBT involves regular sessions with a trained mental health practitioner and may include parents or carers for younger adolescents, with a focus on understanding thoughts, feelings, and behaviours. Participants are community-dwelling youth aged 10–17 who show aggression or violence at referral and whose involvement will not interfere with statutory orders. Outcomes will compare changes in aggressive/violent behaviour and related mental health measures over the follow-up period.
Why it matters
Potential benefit: If successful, this could reduce aggressive and violent behaviour and improve emotional understanding and relationships for vulnerable young people in FCAMHS.
How similar studies have gone: MBT has shown benefits in adolescents for emotion regulation and self-harm in prior research, but using it specifically for aggressive or violent behaviour in FCAMHS populations is relatively novel and less well established.

Exclusion Criteria: * Age under 10 or age 18 or older at the time of referral; * No evidence of aggression and/or violence indicated at referral or assessment; * FCAMHS are only offering a one-off consultation or assessment (e.g., the network around the child requires support to manage risk but additional input is not required); * Child's level of English is not sufficient to engage in the intervention; * Child and/or parents/carers refuse to engage with FCAMHS; * No statutory service is involved in supporting the child; * No statutory service will agree to hold the child's case open for a minimum of six months. * Currently involved in another psychological intervention research study.
