Brief Summary

The aim of this study is to evaluate the effectiveness of a 20-week Dialectical Behaviour Therapy (DBT) skills training group for the treatment of chronic suicidal and non-suicidal self-injurious (NSSI) behaviours in individuals diagnosed with borderline personality disorder (BPD). Previous research has established the effectiveness of a one year comprehensive, combined individual and group DBT treatment. However, in practice, DBT is often offered in a skills only group format. This study will consist of a randomized, controlled trial designed to evaluate the effectiveness of DBT compared to a wait list control. 84 participants will be randomized to the 20-week DBT group or the wait-list and the following outcomes will be assessed:

1. 1.frequency of suicidal and NSSI behaviours
2. 2.symptom distress
3. 3.impulsivity
4. 4.treatment retention
5. 5.skill acquisition and
6. 6.social functioning
