Mobile Health Technology Interventions for Suicide Prevention: Systematic Review

Area of Science:

• Digital health interventions
• Mobile health (mHealth) technology
• Suicide prevention research

Background:

• Digital interventions offer scalable treatment options for self-harm and suicidal ideation.
• Mobile devices can deliver timely, personalized, evidence-based interventions.
• The rise of suicide prevention apps necessitates evidence for safe and effective practice.

Purpose of the Study:

• To review the effectiveness of mobile health technology tools in reducing suicide-specific outcomes.
• To synthesize current evidence on mHealth interventions for suicide prevention.

Main Methods:

• Systematic review of randomized controlled trials (RCTs), pseudo-RCTs, and pre-post observational studies.
• Searched multiple databases including Cochrane, MEDLINE, EMBASE, and PsycINFO.
• Narrative synthesis due to heterogeneity of outcomes; meta-analysis not performed.

Main Results:

• Seven studies met inclusion criteria, evaluating apps like iBobbly, Virtual Hope Box, BlueIce, and Therapeutic Evaluative Conditioning.
• Included apps showed positive impacts on depression, psychological distress, and self-harm, and increased coping self-efficacy.
• No app significantly reduced suicidal ideation compared to control conditions.

Conclusions:

• mHealth interventions show potential for improving suicide-specific outcomes but require further efficacy evaluation.
• Methodological limitations include outcome heterogeneity, concerns with ecological validity, and lack of app regulation/standardization.
• Standardized outcome measures and clear definitions are crucial for future mHealth intervention research in suicide prevention.
