ABSTRACT
BACKGROUND: The purpose of this study is to identify the relationship of sleep quality, physical stress, psychological stress, and job stress among residents and to examine correlations of sleep quality, physical stress, psychological stress, and job stress according to average of working hours per day, frequency of night duty, sleep onset time on night duty and sleeping hour on night duty. METHODS: A descriptive correlation study included 164 residents working at 13 secondary and tertiary hospitals in Gyeong-gi Province who completed a self-administered structured questionnaires. The data were collected from June 1 to August 31, 2016. and analyzed through frequency, percentage, t-test, ANOVA, Scheffe's test, multiple regression analysis by SPSS program version 22.0 (IBM Corp., Chicago, IL, USA). RESULTS: The average level of residents' sleep quality, physical stress, psychological stress, and job stress were 40.30, 16.74, 15.96, and 26.79, respectively. Sleep quality, physical, psychological and job stress have shown statistically significant correlations according to average of working hours per day, frequency of night duty, sleep onset time on night duty and sleeping hour on night duty. Poor sleep quality is related to higher physical, psychological and job stress. CONCLUSIONS: Residents' average of working hours per day is long and sleeping hour on night duty is scarce. Due to this, the level of residents' sleep quality is poor and physical, psychological and job stress are severe. Obviously, sleep quality showed a positive correlation with physical, psychological and job stress. It is necessary to develop effective program to improve the residents' sleep quality and reduce physical, psychological and job stress.
