The role of organizational factors in promoting workers' health in the construction sector: A comprehensive analysis.

• A multidimensional construct of safety climate is proposed, considering the most salient factors from the literature, and including psychological capital as a new factor. • This research contributes to the literature by being the first empirical research, that incorporates the psychological capital factor as an element affecting safety climate, especially in the construction sector studies. • Accurate methodological description. Descriptive analyses and Partial least squares structural equation modelling (PLS-SEM) were used to assess the quality of the measurement instrument and the hypotheses of the proposed model. • This study proposes and validates a structural model to explain workers' mental and physical health as a function of safety climate, mediated by job satisfaction. • The sample of Spanish construction workers was composed by all random observations contained in the EWCS of all workers in the Spanish sector, totaling 232 workers. • Workers' mental and physical health are influenced by several factors, including, but not limited to, safety climate, work-life balance, and job rewards and compensations. • This study provides some recommendations for construction company managers providing a ranking of all the factors affecting the safety climate and the workers' health. Introduction: The number of physical and mental problems caused by occupational accidents and diseases increases every year. To control them, the safety climate at work is a recognized critical factor. However, a widely applicable model to capture the safety climate for various industries and organizations is lacking. Method: This study proposes a theoretical model to measure the direct and indirect effects of safety climate on workers' physical and mental health, mediated by job satisfaction, in the construction sector. We propose a multidimensional construct of safety climate, considering the most salient factors from the literature, and including psychological capital as a new factor. Using data from the last wave of the European Working Conditions Survey (2015) in Spain, the proposed model was validated using structural equation modeling. Results: Our findings suggest that to further improve the mental health of construction workers, work-life balance and job rewards and compensation must be prioritized along with safety climate. As for physical health, safety climate and work-life balance are crucial. Finally, we provide some recommendations for construction company managers based on a ranking of all the factors affecting the safety climate and the workers' health. [ABSTRACT FROM AUTHOR]
