|
Purpose: This study was conducted to identify relationships among circadian types, sleep quality, and adaptation
to night shifts among nurses working on two or three day night duties.
Methods: The participants were 199 ward nurses from two university hospitals in Gyeongnam province. Each nurse worked on two or three day night duties. Data were collected between September 24 and October 14, 2012 and analyzed using t-test, ANOVA, Scheffe test, Pearson correlation, and multiple regression with SPSS/WIN 14.0 program.
Results: Mean scores for sleep quality and adaptation to night shifts was 4.92±1.46 on a 10-point scale and 2.66±0.47 on a 5-point scale respectively. There were no significant differences in sleep quality and adaptation to night shifts according to circadian types of nurses. There were significant correlation between sleep quality and adaptation to night
shifts (r=.25, p<.001). Factors affecting adaptation to night shifts were preference for night shifts, and subjective
health status, which together explained about 35% of the total variance.
Conclusions: Nurses working on two
or three day night duties had low level of sleep quality and adaptation to night shifts. It is necessary to improve
preference for night shifts and subjective health status for improving adaptation to night shifts of nurse.
