결론 및 제언

계를 보였다. 직무스트레스는 우울증상과 유의한 양의 상관관계를 보였다. 우울증

므로 선행연구와 달리 교대 간호사의 주간수면과다증에 관련요인에 대해 더 체계 적으로 파악하였다고 생각한다.

이를 바탕으로 교대간호사의 주간수면과다증을 예방하기 위한 기초자료를 제공할 수 있을 것으로 생각되며 교대 간호사의 주간수면과다증 문제를 개선하기 위해서 는 우선적으로 수면의 질을 증가시키고, 우울증상을 감소시키기 위해 정신․심리적 인 건강문제에 대해 평가하는 프로그램이 시급하며 수면의 효율성을 증진시킬 수 있는 방안이 필요하다고 할 수 있다.

ABSTRACT

-Factors associated excessive daytime sleepiness in shift-working nurses

The purposes of this cross-sectional study were to investigate the prevalence of excessive daytime sleepiness in shift nurses and its correlating factors including job stress, depressive symptoms, and sleep-related characteristics and therefore to provide preliminary data for developing intervention programs to help decrease excessive daytime sleepiness in shift nurses. The present study was conducted on 183 shift nurses working in a tertiary hospital in Suwon, Gyeonggi-do from December 28, 2015 to January 4, 2016.

Key findings of the study were as follows.

The prevalence of excessive daytime sleepiness was 43% (n=79) of participants with a mean score of 9.21 and it was significantly ‘high’ in

participants with perceived health-status as ‘bad’ and in participants with having taken naps more than 3 times in a week (p<.05).

The level of job stress found to be in the medium level with the mean score of 170.78. Regarding distribution of job stress across its subcategories,

‘interpersonal conflict with physicians’ was rated as highest and ‘lack of reward’

was rated as lowest. Job stress was significantly higher in sub groups such as

‘female’, ‘perceived health status as bad’, ‘no more than 5 hours of daily sleep-hour during weekdays’, ‘on current medication’, ‘more than 10 years of work experience’, and ‘a charge nurse’ (p<.05).

The prevalence of depressive symptoms was 62.3% (n=114) of participants with a mean score of 18.87 and it was significantly high in participants of

‘having 2 children’, ‘having no more than 5 hours of daily sleep-hour during weekdays’, ‘taking more than 3 cups of caffeinated beverages’, and ‘having poor sleep quality’ (p<.05).

Excessive daytime sleepiness was in a significant positive correlation with job stress (r=.202, p<.01), depressive symptoms (r=.299, p<.001) and in a significant negative correlation with sleep quality (r=-.330, p<.001).

Hierarchical multiple regression model revealed that significant predictors of excessive daytime sleepiness were ‘sleep quality (ß=-.166, p=.019)’, ‘depressive symptoms (ß=.177, p=.021)’, and ‘more than 10 years of work experience (ß=-.166, p=.019)’. Together the three independent variables accounted for 17.2%

of the variance in excessive daytime sleepiness (R²=.172, adjusted R²=.153,

F=9.231, p<.001).

In the present study, almost half of the shift nurses experience excessive daytime sleepiness, indicating the need for assessing shift nurses’ psychological health status and for developing intervention programs to help promote sleep quality, alleviate depressive symptoms, and therefore relieve excessive daytime sleepiness in this population.

Key words : shift-working nurses, excessive daytime sleepiness, job stress, symptoms of depression
