Background: The prevalence of psychiatric disorders in the workplace is increasing due to occupational and psychological stress and exhaustion. The present study aimed to investigate the prevalence of psychiatric disorders and the influential factors at Zanjan Lead and Zinc Company (ZLZC) in ۲۰۱۹. Methods: This descriptive-analytical study was conducted on ۳۴۷ employees of ZLZC who were selected via stratified random sampling. For the subjects with higher scores of the symptom checklist-۹۰-revised scales than the diagnostic cutoffs, a structured clinical interview was performed in terms of DSM-IV axis I disorders (SCID-I). Data were collected using SCL-۹۰-R and SCID-I. Data analysis was performed using linear and logistic regression analysis. Results: In total, ۴۹.۵% of the subjects were suspected of psychiatric disorders. Job satisfaction, income, and marital status could predict ۲۱.۲% of the global severity index, and no significant correlation was observed between the exposure level to lead and the prevalence of psychiatric disorders.  Conclusion: Considering the high prevalence of psychiatric disorders, it is recommended that proper training be provided on stress management, stress coping strategies, and self-efficacy training to increase the abilities of the staff of ZLZC.
