The Occupational Fatigue Exhaustion/Recovery Scale (OFER) was designed to assess occupational fatigue in nurses. Although the original English version of this instrument has shown high degrees of reliability and validity, a Chinese version of this scale has yet to be verified.
The aim of this study was to evaluate the psychometric properties of the OFER in a population of Chinese nurses.
The scale was translated using translation and back-translation. The validities and reliabilities were evaluated on 923 qualified participants using content validity index, concurrent validity, factorial validity, internal consistency reliability, and test-retest reliability.
The content validity index for the OFER was .92. The correlation coefficients between the scores of the OFER subscales and the criteria in this study (varying from -.498 to .705) verified that the OFER has acceptable concurrent validity. Principal component analysis and confirmatory factor analysis revealed that three factors correspond to the structure of the original instrument and that recovery mediates the relationship between acute and chronic fatigue. The Cronbach's alpha for the chronic fatigue, acute fatigue, and intershift recovery subscales were .83, .85, and .86, respectively. Test-retest reliabilities with correlation coefficients from .61 to .78 were found in the three subscales.
CONCLUSIONS/IMPLICATIONS FOR PRACTICE: OFER is a reliable and valid instrument for assessing work-related fatigue in Chinese nurses. However, further improvement of the acute fatigue subscale is recommended. The OFER has the potential to elicit information that is useful for assessing fatigue in nurses in China. Furthermore, as it differentiates between acute and chronic fatigue, OFER may be an effective tool for guiding the development and implementation of various, related intervention measures.
职业疲劳耗竭/恢复量表（OFER）旨在评估护士的职业疲劳。尽管该量表的原始英文版本已显示出高度的信度和效度，但该量表的中文版尚未得到验证。
本研究的目的是评估OFER在中国护士群体中的心理测量特性。
采用翻译和回译的方法对该量表进行翻译。使用内容效度指数、同时效度、因子效度、内部一致性信度和重测信度对923名合格参与者进行效度和信度评估。
OFER的内容效度指数为0.92。OFER各分量表得分与本研究中的标准之间的相关系数（从-0.498到0.705）证实了OFER具有可接受的同时效度。主成分分析和验证性因子分析表明，三个因子与原始量表的结构相对应，并且恢复在急性和慢性疲劳之间的关系中起中介作用。慢性疲劳、急性疲劳和轮班间恢复分量表的Cronbach's α系数分别为0.83、0.85和0.86。在三个分量表中发现重测信度的相关系数在0.61至0.78之间。
结论/对实践的启示：OFER是评估中国护士工作相关疲劳的可靠且有效的工具。然而，建议进一步改进急性疲劳分量表。OFER有可能获取对评估中国护士疲劳有用的信息。此外，由于它区分了急性和慢性疲劳，OFER可能是指导各种相关干预措施的制定和实施的有效工具。
