Modeling organizational and social factors affecting the occurrence of occupational accidents: the mediating role of public health

Occupational accidents have always been affected by the advancement of technology, with the emergence of emerging risks in the workplace, identifying the causes of accidents requires more careful study. With the aim of recognizing organizational and socio-psychological factors according to the mediating role of individual factors using structural modeling.

This is a cross-sectional-analytical study that was performed using structural equation modeling with AMOS approach in 2019(1398) in Baqiyatallah Hospital. The sample size was 480 people which was determined according to the structural studies model. Conceptual model evaluation was performed using IBM SPSS AMOS version 22.

The results of KMO and Bartlett test for the adequacy of the sample size was 0.890, which indicates the appropriate sample size. The results indicate the mediating role of public health as individual factors in the proposed model. Social factors with two components of work conflict - family and imbalance of rewards - effort has been one of the most important risks of occupational accidents. Also, the size of the organization has a significant relationship with the severity of the accident. Shift work is one of the most important organizational factors that has a significant and negative relationship with the mediating variable. The values of good fit index of X2/DF model, RMSEA, TLI, CFI, GFI and AGFI were equal to 2.315, 0.052, 0.909, 0.939, 0.952 and 0.957, respectively, indicates the optimal proposed model.

The analysis of the study hypotheses showed that the imbalance between reward and effort and the existence of severe conflict between work and family among the subjects is evident. These two factors and the type of work shift have a direct effect on accident severity and public health of people.
