The GBS is composed of 11 items and three subscales. To compute the overall composite GBS score, first average all of the items within each subscale of preparedness, likelihood, and self-efficacy. Then, owing to differing response scales, standardize the mean score for each subscale using the percentage of maximize possible (POMP) method, which expresses the raw scores as a percentage of maximize possible score). Then compute an overall GBS score by averaging the three subscales’ POMP score.
The Gatekeeper Behavior Scale (GBS) is a tool to measure the effectiveness of gatekeeper training by assessing participants’ skills, attitudes, and intentions, which predicts engagement to help those in psychological distress and those at risk of suicide. The GBS is tool for assessing a person’s gatekeeper behavior to question, discuss, motivate, and refer those in psychological distress to mental health support services.
