From safety commitment to safety behavior: The mediating role of safety awareness. [PDF]

PLoS One
To deeply analyze the mechanism of workplace safety climate on employee safety behavior, a conceptual model of employee safety behavior was constructed based on the theory of stimulus-organism-response (SOR). Structural equation modeling was used to test the model and hypotheses.
