Efficacy of suicide prevention gatekeeper training in Israel: Exploring diverse at-risk populations, gender differences, and comparisons between online and in-person training

This study examines the efficacy of a gatekeeper training for suicide prevention among diverse at-risk populations in Israel. One hundred and ninety-three participants, engaging with adolescents, LGBTQ individuals, and the elderly, underwent a four-hour gatekeeper training session, conducted online or in-person. Pre- and post-training self-report questionnaires assessed attitudes toward suicide, perceived knowledge and ability to assist individuals in suicidal distress. Significant improvements were observed in all measures across genders and at-risk populations, with no group differences. An interaction revealed greater knowledge improvement for men. Both training formats demonstrated equivalent effectiveness. Attitudes toward suicide, perceived knowledge, and ability to assist a person in distress were improved. Therefore, incorporating suicide prevention community gatekeeper training for diverse at-risk populations, irrespective of gender, is vital for reducing suicide-related deaths. Online training offers cost-effective options. Future studies should include follow-up assessments for sustained effects.
