203. Occupational stress on depression and sleep among hr professionals in large corporations

Abstract Background Against the backdrop of increasingly sophisticated organizational management and a continuously strengthening performance orientation in large enterprises, HR specialists often bear multiple responsibilities, including policy implementation, emotional coordination, and conflict mediation. Their occupational stress is characterized by both persistence and concealment. Research in the field of mental health treatment indicates that chronic occupational stress can affect individual mental health through emotional exhaustion, cognitive rumination, and physiological hyperarousal mechanisms, and may induce depressive symptoms and sleep disorders. This study aims to systematically analyze the relationship between occupational stress levels, depressive states, and sleep quality among HR specialists in large enterprises, providing empirical evidence for workplace psychological intervention and mental health prevention. Methods A cross-sectional survey was conducted, selecting 312 HR specialists from three large enterprises as the research subjects. Occupational stress levels were assessed using the Job Demand-Control Model Scale, depressive symptoms were measured using the 9-item Patient Health Questionnaire-9 (PHQ-9), and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). The sample was divided into low, medium, and high stress groups based on the ternary scores of occupational stress, and differences in psychological and sleep indicators among the groups were compared. Correlation analysis and multiple linear regression models were used to control for potential confounding factors such as age, length of service, and gender to improve the stability and explanatory validity of the results. To reduce the influence of common method bias, the questionnaires were collected anonymously and completed uniformly during non-working hours. Results The results showed that the PHQ-9 score of the high-stress group was 12.4 ± 4.1, significantly higher than that of the low-stress group (6.1 ± 3.0), with a statistically significant difference (t = 9.37, p
