Technology-Assisted Interventions for Reducing Risk of Suicide: A Meta-Analysis Focused on Suicidal Ideation

BACKGROUND: Suicide is a leading cause of death among adolescents worldwide. Suicide is a complex multifactorial issue and, in 2025, became the third-leading cause of death among individuals aged 15-29. We sought to evaluate the effectiveness of technology-assisted interventions (TIs) in reducing both suicidal behaviour and non-suicidal self-injury among adolescents. METHODS: statistic, and, due to the small number of considered studies, publication bias was assessed using an adaptation of Cochrane's guidelines for the assessment of bias risk. The review was registered with INPLASY, with the code INPLASY202570073. RESULTS: After applying the eligibility criteria, six studies were selected for the analysis. Although the initial conceptual aim pertained to suicidal risk and self-harm more broadly, suicidal ideation was the only outcome consistently reported across the eligible studies; therefore, it served as the primary meta-analytic outcome. CONCLUSIONS: The results highlight that technology-assisted interventions yield an overall statistically significant moderate reduction in suicidal ideation, providing valuable support for the implementation of such interventions during adolescence, although further rigorous research is needed to strengthen the evidence base.
