Abstract: (7 Views)
Background: This stuyd aimed to examine the role of the Behavioral Brain System, emotional processing, and job satisfaction in predicting sleep disorders among medical sciences employees in Lorestan Province, with emphasis on the mediating role of core self-evaluation. The present study was derived from a master’s thesis in the field of clinical psychology.
Materials and Methods: This study was conducted using a descriptive–correlational design on the population of medical sciences employees in Lorestan Province in 2025. A sample of 367 participants was selected through convenience sampling. Data were collected using the Sleep Disorders Questionnaire by Lynch et al. (2003), the Behavioral Brain System Scale by Carver and White (1994), the Emotional Processing Questionnaire by Baker et al. (2007), the Job Satisfaction Questionnaire by Smith et al. (1969), and the Core Self-Evaluation Scale by Judge et al. (1997).
Results: The findings indicated that the Behavioral Brain System and emotional processing did not directly predict sleep disorders; however, they had an indirect effect through core self-evaluation. In addition, job satisfaction predicted sleep disorders both directly and indirectly through the mediating role of core self-evaluation. In other words, employees who had greater ability in emotional processing, higher job satisfaction, and more positive core self-evaluations reported better sleep quality.
Conclusion: The results suggest that sleep disorders among medical sciences employees are a multifactorial phenomenon which, in addition to biological factors, is influenced by emotional skills and occupational conditions. Therefore, interventions, such as improving the work environment, promoting organizational justice, training emotional regulation skills, and strengthening core self-evaluation may help reduce sleep disorders and enhance employees’ psychological and occupational well-being.
