Abstract
As an important influencing factor of construction workers' safety performance, safety stressor has received increasing attention. However, no consensus has been reached on the relationship between different types of safety stressors and the subdimensions of safety performance, and the mechanism by which safety stressors influence safety performance remains unclear. This study proposed a multiple mediation model with ego depletion and self-efficacy as mediators between safety stressors and workers' safety performance. Data were collected from 335 construction workers in China. Results demonstrated that: (1) the three types of safety stressors (i.e., safety role ambiguity, safety role conflict, and interpersonal safety conflict) all had negative effects on workers' safety performance (i.e., safety compliance and safety participation); (2) self-efficacy mediated all the relationships between the three safety stressors and safety performance; (3) ego depletion only mediated part of the relationships between the three safety stressors and safety performance; and (4) only part of the multiple-step mediating effects through ego depletion and self-efficacy were supported. This study made contributions by shedding light on the mechanism by which safety stressors influence workers' safety performance and providing more empirical evidence for the relationship between various safety stressors and the subdimensions of safety performance. Additionally, targeted strategies for improving workers' safety performance were proposed according to the findings.
Highlights
Construction is one of the most dangerous industries which incur thousands of fatal and nonfatal injuries every year (Dzeng et al, 2016; Hasanzadeh et al, 2019; Sanni-Anibire et al, 2020; Moosa and Oriet, 2021)
Safety role conflict, and interpersonal safety conflict were negatively related to safety compliance and safety participation
This study investigated the effects of three types of safety stressors on construction workers’ safety performance and the potential mediating role of ego depletion and selfefficacy in the relationship between these safety stressors and safety performance
Summary
Construction is one of the most dangerous industries which incur thousands of fatal and nonfatal injuries every year (Dzeng et al, 2016; Hasanzadeh et al, 2019; Sanni-Anibire et al, 2020; Moosa and Oriet, 2021). According to the Occupational Safety and Health Administration (2019), the fatal injuries in the U.S construction industry stood at 1008 in 2018. The corresponding figure of China was even more striking with 1752 death toll in the construction industry in the first half of 2018 (Ministry of Emergency Management of the People’s Republic of China, 2018). These incidents or accidents threaten the health and safety of site personnel and bring huge losses to Safety Stressors and Safety Performance construction enterprises (Nodoushan et al, 2020; Zhang et al, 2020; Al-Kasasbeh et al, 2021; Zhou et al, 2021). Despite improvements over the years, safety performance in the construction industry remains unsatisfactory (Gunduz et al, 2018)
