The impact of nurses' stress situation coping on somatization: a mediated moderation model.

Aims: The purpose of this study is to investigate the impact of nurses' stress situation coping levels on somatization symptoms, the mediating effect of depression, and the moderating effect of perceived social support.

Background: As a core part of the global healthcare system, nurses are crucial to patient health and rehabilitation outcomes. However, due to heavy workloads, unreasonable staffing structures, and constant exposure to occupational risks in their workplaces, these factors often place nurses in a high-intensity, high-stress environment, which directly affects their physical and mental health and professional burnout. Coping with stress situations is an important means to help individuals effectively manage stress, reduce negative impacts, and maintain mental health. However, research on the impact of nurses' stress situation coping methods on somatization symptoms is limited.

Methods: This study conducted a cross-sectional survey from December 2022 to April 2023, and finally included 293 nurses working on the front line of tertiary hospitals. Data was collected through questionnaires and analyzed using SPSS 24.0 and the SPSS macro program's Models 7 and 14. This study is an observational study, strictly prepared and presented according to the STROBE checklist.

Results: The somatization symptom scores of the nurses were (27.27 ± 7.33) points, the stress situation coping scores were (59.90 ± 9.64) points, the perceived social support scores were (65.64 ± 12.90) points, and the depression scores were (4.42 ± 4.12) points. The somatization symptom scores of the nurses were positively correlated with the stress situation coping scores and depression scores, and negatively correlated with the perceived social support scores, with correlation coefficients of 0.200, 0.851, and -0.302, respectively. The stress coping level of the nurses had a direct positive impact on somatization symptoms (β = 0.081, p = 0.009), and a direct positive impact on nurse depression (β = 0.202, p = 0.001). Depression had a significant positive impact on somatization symptoms (β = 0.823, p = 0.000), and depression played a mediating role. Perceived social support had a significant negative impact on depression (β = -0.383, p = 0.000). Perceived social support had a significant moderating effect on the relationship between the stress situation coping level and depression (β = -0.121, p = 0.003).

Conclusion: In this study, the stress situation coping methods of nurses had a positive impact on somatization symptoms, had a complete mediating effect on the depression level of nurses, and perceived social support had a significant moderating effect in the pathway from the stress situation coping methods of nurses to depression-mediated somatization symptoms.
