The Gatekeeper Self-Efficacy Scale (GKSES) effectively measures confidence in gatekeeper skills. This new scale demonstrates good reliability and validity for assessing self-efficacy in suicide prevention training.
Area of Science:
- Mental Health
- Psychometrics
- Suicidology
Background:
- Lack of a standardized scale for evaluating gatekeeper self-efficacy.
- Gatekeeper training aims to equip individuals with skills to help those at risk of suicide.
- Self-efficacy is crucial for effective gatekeeper intervention.
Purpose of the Study:
- To develop and validate the Gatekeeper Self-Efficacy Scale (GKSES).
- To assess laypersons' confidence in their gatekeeper skills.
- To establish the reliability and validity of the GKSES.
Main Methods:
- Development of a nine-item scale (GKSES) for self-efficacy assessment.
- Administration of the GKSES to 875 participants before and after gatekeeper training (2010-2017).
- Exploratory factor analysis, correlation with Attitude Toward Suicide Scale, and ANOVA for demographic differences.
Main Results:
- The GKSES demonstrated good fit as a univariate scale.
- Total GKSES scores correlated with positive attitudes toward suicide prevention.
- Self-efficacy improved post-training; higher initial ratings were observed in those with prior contact or training, with greater improvement in novices.
Conclusions:
- The GKSES is a reliable and valid instrument for measuring gatekeeper self-efficacy.
- The scale is simple and useful for assessing confidence in gatekeeper skills.
- Further validation across diverse populations is recommended.
