Outline
To explore the underlying mechanisms among mental health variables, including perceived stress, psychological resilience, depression, anxiety, and insomnia, within the medical staff population.
Between November 1 and December 31,2023, a convenience sampling method was used to survey healthcare workers in Beijing via an electronic questionnaire. We used internationally validated scales to measure stress perception and psychological resilience. Hypothesized relationships between the variables were tested using a structural equation model (SEM) developed based on existing literature.
A total of 2 014 valid questionnaires were collected from 83 medical and health institutions. The scores of the mental health scales were as follows: PSS 16.00 (10.00, 18.00), CD-RISC 63.00 (48.00, 77.00), PHQ-9 3.00 (0.00, 7.25), GAD-7 1.00 (0.00, 6.00), and ISI 5.00 (1.00, 9.00).Psychological resilience showed a potential mediating effect of 5.5%-9.3% on the associations between perceived stress and each psychological symptom. In addition, anxiety symptoms played a stronger mediating role in the pathways from perceived stress to depressive symptoms and insomnia symptoms, accounting for 55.0% and 79.4% of the total effects, respectively. The direct effect of perceived stress on anxiety symptoms was the most prominent (94.5%). The structural equation model demonstrated good overall fit (χ2/df=2.829, RMSEA=0.030), and the hypothesized interrelationships among the variables were supported by the data.
This study demonstrates that psychological resilience and anxiety symptoms are key mediators in the impact of stress perception on mental health, suggesting that optimizing mental health management in healthcare professionals requires integrated strategies focusing on stressor control, early identification of anxiety, and resilience enhancement.
