Functional Family Therapy - Lewisham Youth Justice Service (2018)

Summary: Lewisham youth justice service have shared how they run functional family therapy in their service to support families in reducing the use of violence, offending and poor behaviour.



Functional Family Therapy is a strength-based model, which offers short term, high quality intervention programme for children who are at risk or offending. In general the families have between 8-12 sessions, however, more complex families can have up to 30 sessions over a 3-4 month period, with sessions last around 1 hour.

The intervention programme works with the whole family and the sessions can be conducted in either clinical or home setting. Often the children and their families have histories of poor engagement, lack of access to resources and repeat contact with multiple services.Functional Family Therapy works with the whole family, aiming to reduce negative and defensive communication patterns, increase supportive innervations and promote effective parental discipline.


Please note that there are two distinct strands of Functional Family Therapy, both of which have implemented FFT in the UK.
