Effects of dialectical behaviour therapy on reducing self-harming behaviours and negative emotions in patients with borderline personality disorder: A meta-analysis.

Findings indicate that DBT can reduce self-harming behaviours and improve depression, but effects on suicidal ideation and anger are insignificant.

Given the quality and quantity restrictions of RCTs, more high-quality RCTs need to verify these effects.
