Effectiveness of self-help mobile telephone applications (apps) for suicide prevention: A systematic review.

According to the expansion of suicide prevention applications in recent years, the aim of this study was to review randomized controlled trials (RCTs) and pretest-posttest studies that evaluated the effectiveness of suicide prevention applications. In this systematic review, we searched online databases including Pubmed, SCOPUS, Web of Science, Chocrane Database, and Google Scholar to find randomized controlled trials and pretest-posttest studies published up to Jul 18, 2019. Randomized controlled trials and pretest-posttest of efficacy self-guided telephone applications that reported any primary and secondary outcome of suicidal thoughts and behaviors were included in the review. We evaluated the articles using the CONSORT 2010 checklist. After screening articles, 7 studies were included in this review. Four studies focused on the effectiveness of applications on suicide thoughts and attempt, 2 on effectiveness of applications on self-injury, 4 on depression and anxiety, 1 on impulsivity, and 2 on adaptive strategies. Overall, mobile phone applications were associated with reductions in suicidal ideation scores at post intervention, and enhancement of adaptive skills; however, no evidence of reduction was reported in impulsivity after use of applications. Despite the differences in studies, this review showed that the use of mobile applications had an overall positive effect on reducing the risk of suicide and improving performance and health of patients.
