The severity of occupational accidents and injuries in the construction industry is the greatest across all industries. Few studies have examined the causal relationships among physical and psychological variables affecting the safety behavior of construction workers.
This study aimed to investigate the relationships among three factors (metal health, work ability and sleep quality) influencing the safety behavior of construction workers.
This cross-sectional study was conducted on 204 workers in civil construction projects in Iran. The data were gathered via self-reporting questionnaires. The acquired data were analyzed by the Smart PLS3 software using structural equation modeling with the partial least squares (PLS) regression approach.
The R square revealed an acceptable fineness of the structural model. Similarly, as Q square values were higher than 0.15 for all factors, the predictability of the model was approved. The direct effect of mental health on safety behavior was not significant, but work ability and sleep quality had significant direct effects on safety behavior. Moreover, a decrease in mental health significantly reduced construction workers' sleep quality and work ability.
The results of this study prove that sleep quality and work ability mediate the relationship between mental health and safety behavior. The deterioration of construction workers' mental health can increase the risk of unsafe behavior and occupational injuries. Therefore, appropriate measures need to be taken to maintain and improve the mental health of construction workers.
在所有行业中，建筑行业的职业事故和伤害严重程度最大。很少有研究探讨影响建筑工人安全行为的身体和心理变量之间的因果关系。
本研究旨在调查影响建筑工人安全行为的三个因素（心理健康、工作能力和睡眠质量）之间的关系。
本横断面研究在伊朗的民用建筑项目中对 204 名工人进行。通过自报问卷收集数据。使用结构方程模型和偏最小二乘（PLS）回归方法，通过 Smart PLS3 软件对获得的数据进行分析。
R 方显示结构模型的精细度可接受。同样，由于所有因素的 Q 方值均高于 0.15，因此模型的可预测性得到了验证。心理健康对安全行为的直接影响不显著，但工作能力和睡眠质量对安全行为有显著的直接影响。此外，心理健康状况的恶化显著降低了建筑工人的睡眠质量和工作能力。
本研究结果证明，睡眠质量和工作能力中介了心理健康和安全行为之间的关系。建筑工人心理健康状况的恶化会增加不安全行为和职业伤害的风险。因此，需要采取适当措施维护和改善建筑工人的心理健康。
