Desirable and Adverse Effects of Communicative Suicide Prevention Interventions Among Men

Background: Despite men's high suicide risk, gender perspectives in suicide prevention research are scarce. Aims The goal of this systematic review was to describe the desirable and adverse effects of distribution channels and message strategies of communicative suicide prevention interventions among men. Methods Databases PubMed and Web of Science were searched for quantitative randomized controlled trials (RCTs) and nonrandomized studies examining the effectiveness of male-specific or general communicative interventions among men. Narrative synthesis was used to summarize findings. Results: Fifty-five studies published in peer-reviewed articles until October 15, 2021, were included. Findings demonstrate that interpersonal, mass media, and digital media interventions impact suicide-related outcomes preventively. Mass media interventions are not suitable to impact men's emotions in a prevention-desirable way. Message strategies interactivity, emotional appeals, and clear calls to action demonstrated high effectiveness, while expert exemplars, visualizations, and personalization were rather ineffective. Limitations However, the review was not able to prove causality, could not distinguish between multichannel interventions and single-channel interventions, or between specific combinations of channels and message strategies. Discussion: The systematic review provides some guidance on which channels and message strategies to apply in communicative suicide prevention for men.
