BackgroundThe objective is to summarize evidence from systematic reviews, scoping reviews, and meta-analyses evaluating the effects of any format of Internet-based, mobile-, or telephone-based intervention as a technology-based intervention in suicide prevention.Materials And MethodsThis is an umbrella review, that followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement guidelines. An electronic search was done on September 29, 2022. Data were extracted by reviewers and then methodological quality and risk of bias were assessed by A Measurement Tool to Assess Systematic Reviews-2. Statistical analysis was done by STATA version 17. Standard mean difference was extracted from these studies and by random effect model, the overall pooled effect size (ES) was calculated. I2 statistic was used to assess the heterogeneity between studies. For publication bias, the Egger test was used.ResultsSix reviews were included in our study, all with moderate quality. The overall sample size was 24631. The ES for standard mean differences of the studies is calculated as - 0.20 with a confidence interval of (-0.26, -0.14). The heterogeneity is found as 58.14%, indicating a moderate-to-substantial one. The Egger test shows publication bias.ConclusionOur results show that technology-based interventions are effective. We propose more rigorous randomized controlled trials with different control groups to assess the effectiveness of these interventions.Copyright: © 2024 Journal of Research in Medical Sciences.
