The Moderating Effect of Nursing Practice Environment on the Relationship between Clinical Nurses' Sleep Quality and Wellness

Abstract

This study examined the moderating effect of nursing practice environment on the relationship between clinical nurses' sleep quality and wellness. The wellness of clinical nurses is a direct outcome of individual-level health behaviors and organizational environmental factors. This study was a cross-sectional analysis. Participants were clinical nurses recruited using convenience sampling. The Nurse Practice Environment Scale, Wellness Index, and Pittsburgh Sleep Quality Index, Korean version (PSQI-K) were used. Data collected from 1874 nurses were analyzed using descriptive statistics and hierarchical multiple regression analyses. A total of 95.3% of the participants were women, and the mean age was 28.8 years. Further, 42.4% of the participants had a nursing career of 5 years or longer. The mean score for nursing practice environment was 2.24 and the mean PSQI-K score was 9.39. Nurses with less than 1 year of experience reported lower wellness scores. The wellness scores decreased with poorer sleep quality, and a more positive evaluation of the nursing practice environment predicted higher levels of wellness. Nursing practice environment had a moderating effect on the negative association of nurses' poor sleep quality with their wellness. Regarding management, individual strategies for nurses' well-being and organizational improvement policies may improve the nursing work environment.
