Objective and Subjective Measures of Sleep and their Relationships with Burnout in the Shift Working Nurses

Abstract

Objective:The purpose of this study was to objectively and subjectively evaluate different types of sleep for nurses working in shifts, and to clarify the relationship between each sleep and burnout state. Methods: The subjects were 20 female shift-working nurses. Actiwatch Spectrum Plus was used for objective evaluation of sleep. The St. Maryʼs Hospital Sleep Questionnaire was used for subjective evaluation. In addition, the Maslach Burnout Inventory-HSS Japanese version was used for burnout evaluation. Results: In objective evaluation, emotional exhaustion was found to have a significant positive correlation with nighttime sleep after the day shift, and a significant negative correlation with the percent sleep of post-night shift sleep. In the subjective evaluation, emotional exhaustion was found to have a significant negative correlation with the depth and soundness of sleep on holidays after the night shift. In the objective evaluation, personal accomplishments were significantly negatively correlated with the percent sleep of sleep after the night shift. Conclusion:The discrepancy between the subjective and the objective evaluations is suggested to be one characteristic of burnout.
