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.
