ABSTRACT
OBJECTIVE: This study investigated the effects of occupational stress, anxiety, depression, and sleep disturbance on the level of fatigue among public health nurses (PHNs). DESIGN: The study had a cross-sectional, correlational survey design. MEASURES: A total of 198 PHNs were enrolled from 30 public healthcare centers/offices. Data were collected between May and July 2021 using a structured questionnaire to investigate the general characteristics, occupational stress, anxiety, depression, sleep disturbance, and fatigue of the participants. Descriptive statistics and multiple regressions were used to determine fatigue and its influencing factors among PHNs. RESULTS: The participants showed high fatigue and occupational stress levels due to a lack of rewards. The percentage of participants with mild-to-severe anxiety and mild-to-severe depression, and those who identified themselves as poor sleepers were 44.9%, 50.5%, and 70.2%, respectively. High levels of sleep disturbance (ß = .23, p < .001), occupational stress (ß = .21, p < .001), anxiety (ß = .20, p = .016), depression (ß = .17, p = .043), being younger (ß = -.15, p = .004), and being a regular worker (ß = .13, p = .017) were influencing factors of fatigue. CONCLUSIONS: Individual efforts and organizational interventions to enhance sleep quality are needed to relieve fatigue among PHNs. Further, organizational support can be considerate of young nurses and regular workers, and alleviate their occupational stress. Moreover, anxiety and depression should be managed efficiently to reduce fatigue.
