Randomized controlled trial of an online suicide prevention gatekeeper training program: Impacts on college student knowledge, gatekeeper skills, and suicide stigma

Background: Suicide prevention gatekeeper training programs offer a unique opportunity to increase knowledge about suicide prevention, enhance risk identification, and reduce suicide-related stigma. Aims: This study evaluated the efficacy of an online suicide prevention gatekeeper training program in a randomized trial. Method: Participants were US college students (N = 388). Participants (69.3% women) had a mean age of 19.01 years and identified primarily as Hispanic/Latinx (52.1%) and non-Hispanic White (22.4%). Participants completed pre- and posttest surveys and were randomly assigned to either the ASK About Suicide to Save a Life (AS + K?) suicide prevention gatekeeper training program or an information-only comparison intervention. Results: Participants in the AS + K? condition reported significantly greater gatekeeper preparedness and self-efficacy, and lower stigmatized attitudes at posttraining, as compared with those in the comparison condition. There were no significant differences in likelihood of using gatekeeper skills or suicide-related knowledge across groups. Limitations: This short-term study was not able to assess behavioral change resulting in use of gatekeeper skills over time. Conclusions: Completion of gatekeeper training resulted in increases in preparedness and self-efficacy for engaging in gatekeeper behaviors, as well as a reduction in suicide-related stigma. Despite small intervention effects, the online AS + K? training appears to be a promising program.
