Development and Validation of the Gatekeeper Behavior Scale.

Background: Community-based gatekeeper trainings are effective tools in increasing gatekeeper skills but few validated measures assess impact.

Aims: This study aimed at determining the validity of an 11-item Gatekeeper Behavior Scale (GBS) to assess gatekeeper skills that predict behavior.

Method: To validate the scale, 8,931 users were administered GBS surveys at pretraining, posttraining, and follow-up periods.
