Practice-based outcomes of dialectical behaviour therapy (DBT) targeting anger and violence, with male forensic patients: a pragmatic and non-contemporaneous comparison.

Objective: To examine the effectiveness of an eighteen-month treatment based on dialectical behaviour therapy (DBT) targeting anger and violence, on a group of male forensic patients.

They completed three psychometric tests at pre-, mid- and post-treatment and at a six-month follow up.
