This study aimed to investigate the association between non-organizational factors and occupational accidents.<br> <strong>Materials and Methods:</strong> In this descriptive study the structural equation modeling was applied on the data that was collected using a self-developed questionnaire. The random selected sample (n=360) included damaged people referred to the emergency department in Tehran province for treatment during a five-year period (2019-2015). The data analysis was carried out using IBM SPSS AMOS v. 23.0. The goodness of fit indices, including &chi;2/df, RMSEA, GFI, CFI, NFI, and TLI, were evaluated.<br> <strong>Results:</strong> The mean age and work experience of the experts&#39; panel was 37.52&plusmn;2.73 and 9.90&plusmn;3.18 years, respectively. The Cronbach&#39;s alpha coefficient of the non-organizational factors of occupational accidents was calculated as 0.86. Generally, 35.3% of accidents were due to slip and fall, as well as falling the heavy object with 24.1%. The non-organizational index was estimated at 2.95. The factor analysis findings showed a statistically significant association between the non-organizational factors and the occupational accidents (p<0.05).<br> <strong>Conclusion:</strong> The results showed a reverse and significant association between the index of non-organizational factors with the title and type of accidents, cause of accidents, type of outcome or damage caused by accidents, and time of accident occurrence. Additionally, this index indicated a direct significant association with the gender, age, work experience, education, marital status, and the type of shift work schedule of the affected people.</span></span></p> Occupational Accidents,Analysis,Structural Equation Modeling, 31 38 http://johe.rums.ac.ir/browse.php?a_code=A-10-134-3&slc_lang=en&sid=1 Hossein Farahbod hossein_farahbod@yahoo.com 22400319475328460011124 22400319475328460011124 No MSc in Health, Safety, Environment (HSE), Dept. of Health, Safety, and Environment, Faculty of Engineering, Islamic Azad University, Central Tehran Branch, Tehran, Iran.
