Abstract

Occupational stressors have long been recognized as an important risk factor for injury accidents. The mechanisms underlying the relationships among challenge stressors, hindrance stressors, safety outcomes (occupational injuries), emotional experiences (attentiveness), and job performance (task performance) were investigated from the perspectives of the challenge–hindrance stress model and the conservation of resources theory. This study collected multi-source data over two timepoints for 105 safety supervisors and 379 construction workers in China. Results revealed that both challenge and hindrance stressors were positively related to occupational injuries, but only challenge stressors were positively associated with attentiveness. In addition, occupational injuries mediated the relationship between both challenge and hindrance stressors and task performance, while attentiveness mediated only the relationship between challenge stressors and task performance. These findings contribute to our knowledge of stress management in the construction project context and provide recommendations for stress management for front-line workers at construction sites.

Highlights

Occupational health and safety are a major focus in the practice of construction [1].The International Labor Organization (ILO) reported that there are 374 million non-fatal job-related injuries every year [2]
The results indicate that challenge stressors are positively related to both attentiveness (r = 0.111, p < 0.05) and occupational injuries (r = 0.320, p < 0.001); hindrance stressors are positively associated with occupational injuries (r = 0.146, p < 0.01); attentiveness is positively correlated with task performance (r = 0.500, p < 0.001); occupational injuries are negatively correlated with task performance (r = −0.107, p < 0.05)
construction workers (CWs) work in a complex physical environment amid a range of potential hazards, including exposure to extreme temperatures, loud noises, unsuitable lighting, etc

Summary

Introduction

Occupational health and safety are a major focus in the practice of construction [1]. The International Labor Organization (ILO) reported that there are 374 million non-fatal job-related injuries every year [2]. The United Kingdom Health and Safety Executive (HSE) reported that there was a downward trend in the self-reported and employer-reported rates of workplace non-fatal injuries from 2000 to 2019, non-fatal injuries resulted in 4.7 million lost workdays in. Construction is one of the most dangerous industries, with a large number of accidents and higher than average incidence rates of work-related injuries [5]. Because work-related accidents and injuries often occur on construction sites, the research and construction practice have paid more attention to the issues concerning occupational health and safety [6,7]
