Workplace safety is a complicated phenomena and behavioral safety in the construction industry is even more so. The Aim of this study was the development of a new model for understanding the factors influencing unsafe behavior in construction industry. Methods: In the current quantitative study, a three-stage Structural Equation Model (SEM) was conducted on two main construction workplaces in Iran. In the first stage, the measurement model was tested by confirmatory factor analysis. Then, a modified structural model was extracted for the workplace 1. Finally, the modified model was evaluated in the workplace 2. LISREL 8.8 was used for data analysis process. Results: Goodness-of-fit indices indicated the modified structural model in the workplace 1 was confirmed in the workplace 2 (GFI=0.93 SRMR=0.04 RMSEA=0.06 CFI=0.97 NFI=0.98 χ2/df=1.98). Client safety climate had the highest correlation (SPC=0.87, t-value=16.21) with overall safety climate. Attitudes and beliefs had the greatest correlation (SPC=0.87, t-value=13.34) with overall individual factors. The physical condition had the highest correlation (SPC=0.77, t-value=7.69) with the overall safety performance. Conclusion: For implementing of the effective interventions in the construction industry, we must use an integrated and good-fit model to understanding factors influencing unsafe behavior. The current model can help us to understanding the factors influencing unsafe behavior in construction projects. %> http://ioh.iums.ac.ir/article-1-1038-en.pdf %P 27-37 %& 27 %! %9 Full Text %L A-10-568-5 %+ Department of Occupational Health Engineering, Alborz University of Medical Sciences, Karaj, Iran %G eng %@ 1735-5133 %[ 2015
