| Summary: | Background and Objective The purpose of this study was to investigate the effect of morningness-eveningness type on nurses relative to sleep quality, depressive symptoms and occupational stress. Methods Data was collected using self-administering questionnaires by 257 three eight-hour randomly rotating shift system nurses at St. Vincent’s Hospital. Questionnaires were composed of baseline demographic data, Korean version of Morningness-Eveningness Questionnaire, Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Beck Depression Inventory and Korean Occupational Stress Scale. Kruskal-Wallis H test and analysis of covariance were used to identify significant differences in sleep parameters, depressive symptoms and occupational stress according to morningness-eveningness type. Results There was significant difference in Subjective Sleep Quality score (p = 0.018). Post hoc analysis revealed differences between eveningness vs. morningness (p = 0.001) in Subjective Sleep Quality score. There were tendencies in sleep efficiency, PSQI total score and ESS between morningness-eveningness type. However, there were no significant differences in total sleep time, depressive symptoms and occupational stress including eight sub-categories according to morningness-eveningness type. Conclusions Eveningness type nurses revealed lower Subjective Sleep Quality and tendency for poor sleep efficiency, poor overall sleep efficiency and more severe daytime sleepiness than other type. However, morningness-eveningness were not decisive factors for total sleep time, depressive symptoms and occupational stress. Short-term medication, workers’ chronotypes consideration and naps before night shifts may be helpful in improving mental health and quality of life for shift nurses, especially for evening shifts. |
