Abstract
OBJECTIVE: Premenstrual Syndrome is also known as premenstrual tension syndrome because of the pronounced premenstrual mental and emotional anomalies. This study focuses on the association between occupational stress, sleep quality and premenstrual syndrome in clinical nurses and the mediating role of sleep quality. METHODS: A cross-sectional study was conducted to measure occupational stress, sleep quality and premenstrual syndrome in 415 clinical nurses using the Chinese Nurses Stressor Scale, the Pittsburgh Sleep Quality Index Scale, and the Premenstrual Syndrome Scale. SPSS was used to explore the relationship between the variables, and AMOS was used to explore the mediating role between the variables. RESULTS: Nurses' occupational stress positively predicted PMS (β = 0.176, p < 0.001), and the regression coefficients for sleep quality were significantly different for both paths of nurses' occupational stress (β = 0.665, p < 0.001) and PMS (β = 0.261, p < 0.001). The mediation effect accounts for 49.57% of the total effect. CONCLUSION: This study revealed a notably high incidence of PMS among clinical nurses in China, with occupational stress and sleep quality significantly correlated with PMS. Sleep quality played an intermediary role between occupational stress and PMS. Consequently, managers should prioritize addressing occupational stress, mitigating PMS symptoms, enhancing nurses' health and nursing quality, and preventing nursing risks through mental health support and improving sleep quality.
