Most nurses in Korea work rotating shifts, an important contributor to fatigue. The Occupational Fatigue Exhaustion Recovery (OFER) Scale assesses work-related fatigue among nurses. In this study, we aimed to translate and culturally adapt the Korean version of this scale (OFER-K) with nurses working rotating shifts in Korea. Instrument adaptation was performed using committee-based translation, cognitive interviewing, and expert panel interviewing. Criterion validity, convergent validity, construct validity, internal consistency, and test-retest reliability were examined as psychometric properties of the OFER-K. An online survey was completed by 331 nurses; 107 of these nurses completed a second survey after 1 month to assess test-retest reliability. The overall Cronbach's alpha was 0.88. The correlation between participants' initial and retest responses for the total scale was 0.64 (p < .001). The chronic fatigue subscale was stable over time, t(106) = -1.76, p = .08. Criterion and convergent validity were supported by correlations between the OFER-K scale and the Chalder Fatigue Questionnaire, Epworth Sleepiness Scale, and Pittsburgh Sleep Quality Index. Confirmatory factor analysis showed a good fit using a three-factor model. The findings of this study showed that the OFER-K scale is a reliable and valid instrument for assessing chronic fatigue, acute fatigue, and inter-shift recovery in Korean nurses. Future research using this scale may lead to a better understanding of the antecedents and consequences of nurse fatigue and could provide important information to nurse researchers, administrators, and policymakers for developing interventions to reduce nurse fatigue.
大多数韩国护士上轮班，这是导致疲劳的一个重要因素。职业疲劳衰竭恢复（OFR）量表评估护士的工作相关疲劳。本研究旨在翻译和文化适应韩国版该量表（OFR-K），对象为韩国轮班工作的护士。仪器适应采用委员会翻译、认知访谈和专家小组访谈进行。OFR-K 的心理测量学特性包括效标效度、收敛效度、结构效度、内部一致性和重测信度。通过在线调查完成了 331 名护士的调查；其中 107 名护士在 1 个月后完成了第二次调查，以评估重测信度。总体 Cronbach's alpha 为 0.88。参与者对总量表的初始和重测反应之间的相关性为 0.64（p<0.001）。慢性疲劳分量表在时间上是稳定的，t(106)=-1.76，p=0.08。OFR-K 量表与 Chalder 疲劳问卷、Epworth 嗜睡量表和匹兹堡睡眠质量指数之间的相关性支持效标和收敛效度。验证性因子分析显示，使用三因素模型具有良好的拟合度。本研究的结果表明，OFR-K 量表是一种可靠有效的工具，可用于评估韩国护士的慢性疲劳、急性疲劳和轮班之间的恢复情况。未来使用该量表的研究可能会更好地了解护士疲劳的前因后果，并为护士研究人员、管理人员和政策制定者提供重要信息，以制定减少护士疲劳的干预措施。
