Safety behavior of employees is a key factor in ensuring workplace health and safety. Hence, it's important to explore factors that affect employees' safety behavior, which would be beneficial to prevent accidents and injuries and reduce economic loss. Safety behavior is influenced by self-control capacity of individual and the allocation of self-control resources. In safety-related industries, employees need to cope with multiple work goals, and safety is usually regarded as a secondary task. Therefore, the limited self-control resources would be allocated to the primary task first, resulting in inadequate self-control resources in safety-related tasks and causing ego-depletion, which in turn impair the safety performance.
Drawing on the limited strength model of self-control, we adopted three sub一studies to explore the short-lived and long-term effect of self-control demand on safety performance through ego-depletion, and the effect of team self-control demand on team safety performance and safety outcome through team resource depletion at the team level, respectively. By integrating the strength model of self-control and dual-process theory together, the moderating effects of trait self-control and safety descriptive norm on the short-lived and long-term ego-depletion effect were examined.
Specifically, study 1 was a diary study using experience sampling method to explore the short-lived effects of self-control demand on safety behavior through ego-depletion, and the moderating effect of trait self-control and safety descriptive norm on the ego-depletion effect. Results showed that self-control demand reduced safety compliance through short-lived ego-depletion; trait self-control buffered the effect of the self-control demand on short-lived ego-depletion, and safety descriptive norm buffered the effect of short-lived ego-depletion on safety compliance.
Study 2 was a longitudinal study to explore the long-term effects of self-control demand on safety behavior through ego-depletion, and the moderating effect of trait self-control and safety descriptive norm on the long-term effect. Results showed that sustained self-control demand reduced safety compliance and safety participation through long-term ego-depletion; self-control demand on sustained trait self-control buffered the effect of the resource depletion, and safety descriptive norm buffered the effect of long-term ego-depletion on safety compliance and safety participation; meanwhile, safety compliance would result in ego-depletion, however, moderated safety participation would reduce ego-depletion.
Study 3 considered team as a unit to explore the effect of self-control demand on team safety behavior through deletion at the team level, and the moderating effect of team safety descriptive norm level and team safety descriptive norm strength on the team depletion effect. Results showed that team-level self-control demand reduced team safety compliance and team safety participation through team depletion, thereby increased safety outcome; the effect of team depletion on team safety compliance and team safety participation was influenced by the joint effect of team safety descriptive norm level and team safety descriptive norm strength: the weakest negative effect occurred under the levels of high norm strength and high norm levels, while the strongest negative effect occurred under the levels of high norm strength and low norm levels…… |
