Effectiveness of systemic family therapy versus treatment as usual for young people after self-harm: a pragmatic, phase 3, multicentre, randomised controlled trial
Cottrell, David J et al. The Lancet Psychiatry 2018. Volume 5 , Issue 3 , 203 – 216
In keeping with the review by Aggarwal and colleagues (Evidence Based Mental Health 2018), this large randomised controlled trial undertaken across 40 sites showed that brief/intermittent family therapy did not add anything to usual care for the treatment of young people with self-harm. Family-based interventions probably need to form a substantial part of care if they are to make a difference to outcomes for this group of young people.
