Summary
Dialectical Behaviour Therapy (DBT) effectively reduces self-harm and impulsivity in women with borderline personality disorder (BPD). These positive effects on core BPD symptoms and alcohol use are sustained for six months after treatment completion.
Area of Science:
- Psychiatry
- Clinical Psychology
- Behavioural Science
Background:
- Borderline personality disorder (BPD) is a complex mental health condition.
- Dialectical Behaviour Therapy (DBT) is a recognized treatment for BPD.
- Previous research indicated DBT's positive impact on BPD symptoms.
Purpose of the Study:
- To evaluate the sustained efficacy of Dialectical Behaviour Therapy (DBT) for borderline personality disorder (BPD).
- To assess long-term effects of DBT on parasuicidal behavior, impulsivity, and substance abuse in female BPD patients.
Main Methods:
- A randomized controlled trial comparing 52 weeks of DBT to treatment as usual (TAU).
- Inclusion of 58 female BPD patients with and without substance abuse.
- Follow-up assessment at 78 weeks (6 months post-treatment discontinuation).
Main Results:
- DBT significantly reduced parasuicidal behavior and impulsivity compared to TAU.
- Sustained benefits in alcohol use were observed six months after DBT discontinuation.
- No significant differences in drug abuse between DBT and TAU groups.
Conclusions:
- Dialectical Behaviour Therapy demonstrates sustained effectiveness for core borderline personality disorder symptoms.
- DBT shows lasting positive effects on alcohol use in female BPD patients.
- Treatment effects on drug abuse require further investigation.
