About the project: Functional Family Therapy – Gangs

Functional Family Therapy Gangs (FFT-G) is an intensive, home-based programme that provides three to five months of therapy to families. The programme was developed by FFT LLC and delivered by Family Psychology Mutual (FPM).

FFT-G is aimed at young people aged 10-17 at risk of involvement in County Lines Drug Networks; child criminal exploitation; child sexual exploitation, missing (from home or care) episodes and/or potential/actual gang as identified by police or other statutory.

In the early stages, contact is provided to families several times a week, with home visits lasting 60 to 90 minutes. In later stages of the intervention, contact is reduced to weekly. The programme aims to improve the safety, well-being and stability of children and families, and reduce offending.


Given the promising findings of the evaluation (download the report below), we are funding an efficacy randomised control trial of FFT-G. The efficacy study will focus on assessing whether FFT-G can reduce offending for CYP aged 10-17 involved in gangs, child sexual exploitation (CSE) and child criminal exploitation (CCE). The efficacy study will also include an implementation and process evaluation component.

The project delivery will run for 26 months, with the final report published by Summer 2027.
