Digital Interventions for Symptoms of Borderline Personality Disorder: Systematic Review and Meta-Analysis

Area of Science:

• Digital mental health
• Psychiatry
• Behavioral science

Background:

• Borderline personality disorder (BPD) has limited global care access.
• Digital interventions offer a scalable solution to bridge the treatment gap.
• Persuasive System Design (PSD) principles can enhance digital intervention engagement.

Purpose of the Study:

• To systematically review digital interventions for BPD symptoms.
• To assess the efficacy of these interventions.
• To explore the association between intervention features (including PSD) and treatment outcomes.

Main Methods:

• Systematic review and meta-analysis of automated digital interventions for BPD.
• Searched major databases (Embase, MEDLINE, PsycINFO, Cochrane).
• Analyzed 40 studies (6611 participants), focusing on RCTs and PSD elements.

Main Results:

• Digital interventions significantly reduced paranoia (g=-0.52) and suicidal ideation (g=-0.13).
• Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT) based interventions were more effective for suicidal ideation.
• Interventions using reminders, self-monitoring, and behavioral rehearsal improved suicidal ideation outcomes.

Conclusions:

• Digital interventions are effective for reducing suicidal ideation and paranoia in BPD.
• Specific design features, particularly for suicidal ideation, enhance treatment efficacy.
• Transdiagnostic digital interventions show potential for managing BPD symptoms.
