Objective: Borderline Personality Disorder (BPD) is a significant mental illness, associated with an increased risk of self-harming and suicidal behaviours. The prevalence of BPD in mental health settings is up to 23% in outpatient settings, and 43% in inpatient settings. The standard application of Dialectical Behavior Therapy (DBT) for the treatment of BPD has substantial evidence demonstrating efficacy. However, this treatment option is limited within SA Health. This study aimed to evaluate the effectiveness of an established, shorter and more available intervention, DBT skills training group (DBT-ST), in a publicly-funded community mental health setting.
Method: Participants (114 people with BPD) attended an 18-20 week DBT-ST in a community mental health setting between 2010 and 2016. The study utilised a quasi-experimental design with a within-persons waitlist control group. Primary outcomes were: BPD symptoms, general psychological distress, depression, and rate of Emergency Department (ED) presentations and psychiatric inpatient bed-days.
Results: Participants showed a clinically significant reduction in BPD symptoms, general psychological distress and depression. The waitlist control group showed no significant improvement in BPD symptoms. The rate of ED presentations was significantly reduced by approximately 50%. There was an emerging trend for a reduction in psychiatric inpatient bed-days however there was insufficient power to assess this.
Conclusion: Participation in DBT-ST has been shown to be an effective and accessible treatment for people with BPD, which can be life changing. Additionally, given the prevalence of BPD, DBT-ST can create substantial cost saving for SA Health as DBT-ST participants have decreased contacts with ED.
