| In an effort to reduce injury rates, the U.S. safety industry is urging employers to invest in safety culture. Gilbert's (1978) model of performance engineering may provide guidance for design of culture related interventions. Model testing focused on three contextual variables---communication, resource availability, and incentives---and effects on safety motivation ( n = 316). Incentives, which mediated the indirect effects of communication and resource availability, was shown to exert significant influence on safety motivation. A between-group ANOVA was also conducted (n = 19) to determine predictive value of the model relative to injury costs; however no significant relationships were found. Study findings indicate that continued investigation of Gilbert's (1978) theory as a universal model of safety culture is warranted. |
