High workplace accident and fatality rates have made the measurement of safety behaviours in job applicants a primary concern for organisations. Employee safety behaviours have been defined by a number of actions, including: safety compliance, participation, voicing, and consciousness. The significant role that these safety behaviours play in maintaining workplace safety argues strongly for the need of tools which can be used to measure these behavioural tendencies in job applicants. With this information, job applicants with these safe behaviours can be selected for high-risk positions over those without. To address this problem the Safety Behaviour Test (SBT) was developed as a gamified assessment tool, designed to objectively measure safety behaviour within an animated work environment simulation. The main purpose of this study was to investigate whether the SBT has criterion-related validity. To conduct the validation 200 participants were recruited. 100 of which completed the SBT (SBT participants), while the other 100 participated as independent criterion data sources (acquaintances) and reported on the SBT participants’ safety behaviours. The SBT participants’ scores were correlated with the data on the individual’s actual safety behaviour provided by the acquaintance. Results indicated that the SBT captures authentic safety behaviour and has criterion-related validity. The practical and theoretical value of the SBT’s criterion-related validity in the reduction of workplace accidents is discussed.
