A Quantitative Model for Safety Working Behaviors of Employees in Construction Projects Based on the Theory of Planned Behavior: A Case Study of Twin Towers Project by Telecommunication Company of Iran
This study examined the influential factors of safety working behavior. Accordingly, the variables of attitude, subjective norm, and perceived behavior control in the theory of planned behavior were studied. This cross-sectional and descriptive-analytic study was conducted on 240 employees working in the construction workshop of the Central Twin Towers Project by Telecommunication Company of Iran (TCI) from February 2017 to September 2017. The required information was collected using a researcher-made questionnaire. The collected data were analyzed using SPSS v. 23 and LISREL v. 8.8. According to the Pearson correlation, there was a significant correlation between the five variables of the questionnaire. In order to determine the validity of the confirmatory factor analysis and assess the reliability of the questionnaire, Cronbach's alpha was used. Then, the research hypotheses were tested by a structural equation model. The results showed that the effect of attitude (with the intensity of 0.49) and subjective norm (with the intensity of 0.46) on the behavioral intention was more than the perceived behavioral control (with the intensity coefficient of 0.19). According to the findings of this research, in order to improve safety-working behavior, corrective measures should be on the agenda to improve the attitudes and subjective norms of employees.
