When and how personality predicts workplace safety: Evaluating a moderated mediation model.

INTRODUCTION

Though previous research has linked personality and workplace safety, results have been inconsistent. Aims of the present study were to understand when and how personality factors predict safety performance.

METHODS

With 492 working adults, a moderated mediation model was tested whereby the relationship between personality and safety behavior was mediated by safety motivation and moderated by situation strength (i.e., safety climate perceptions).

RESULTS

Findings indicate that, aside from extraversion, safety motivation mediated all relationships between FFM personality traits and safety behavior. The mediated relationship between conscientiousness and safety motivation was attenuated by safety climate perceptions. However, relationships between all other personality traits and safety motivation, and ultimately safety behavior, remained consistent or, in the case of extraversion, was augmented at higher levels of safety climate perceptions.

CONCLUSION

Results demonstrate an empirical basis for how and when personality translates into safety behavior at work. Additionally, findings provide a theoretical explanation for the mixed results among previous studies of personality's relationship with safety outcomes. Implications are discussed for employee selection and training practices in safety-intensive industries.
