Abstract

The Effect of Sleep Enhancement Behaviors in Shift-work Nurses on Their Sleep Quality, Fatigue and Depression Levels

This study aims at finding out the effect of sleep enhancement behaviors on shift-work nurses in terms of sleep quality, fatigue and depression levels. The study's design is similar to that of the non-equivalent control group non-synchronized design for which the author won approval with the university authorities before the study began (KWNUIRB-2015-04-003-001). The length of data collection period was 39 days between May 7 and June 14, 2015, with the experiment treatment period reaching two weeks afterward. The test subjects were 90 shift-work nurses with the length of service fewer than 18 months who worked in an undisclosed hospital in a city, which become an accessible population. Out of the population, 60 test subjects were selected based on the cutoff quality-of-sleep score over and above 31 points as well as their general characters. This fact was then informed on each of the subjects who were divided into the test group (odd numbers) and control group (even numbers) in equal numbers through a drawing in the order of arriving at their workplace.
In order to minimize the diffusion effect of experiment treatment, the author investigated the control group ahead of the test group and asked all the test subjects to sign a consent form that they could quit any time during the experiment if they wished so. For both the test and control groups, the author undertook after-the-fact investigation in two weeks following the experiment. The investigation was made on the control group without any treatment while to the test group an English lavender (Lavandula angustifolia, 100% organic oil) aroma therapy was administered every day including off-days before their sleep after the shift (morning, afternoon, or night shift). In addition, the test group was given sleep masks and relaxing music for sound sleep. Before undertaking the test, the author told the test subjects on how to proceed and what to be careful in writing. After their sleep, each subject was asked whether she inhaled the aroma, wore the sleep mask, and listened to the music.
The quality of sleep was measured by a measurement tool developed by Lee (2005), with some modifications while for the degree of fatigue was determined by a tool for nurses developed by Chang (2013). As for the level of depression, a Korean version of Beck's depression scale (K-BDI) as modified by Lee, et. al (1995) was used.
The data were analyzed by SPSS/WIN ver. 18.0, with reliability test checked by Cronbach's alpha coefficient, general features by numbers, percentages, averages, and standard deviations, homogeneity test by the chi-square test and Fisher′s exact test, and difference test by the t-test. The results are as follows:
The first hypothesis "the test group that went through sleep enhancement behaviors would be different from the control group that didn't do so in terms of the quality-of-sleep score" was supported (t=-2.189, p=.035).
The second hypothesis "the test group that went through sleep enhancement behaviors would be different from the control group that didn't do so in terms of the fatigue score" was supported (t=-6.197, p<.001).
The third hypothesis "the test group that went through sleep enhancement behaviors would be different from the control group that didn't do so in terms of the depression score" was supported (t=-4.789, p<.001).
In conclusion, sleep enhancement behaviors that relied on visual, auditory, and olfactory senses had a positive impact on the shift-work nurses' quality of
sleep, fatigue and depression levels. Hospitals thus need to pay more attention to the issue of sleep quality for their nursing staff that may affect the effectiveness of shift work in significant ways while nurses themselves must put more effort in improving the quality of sleep by looking for sleep enhancement behaviors suitable to their lifestyle.
