Psychometric properties of the Korean version of the Stanford Presenteeism Scale in a nurse population

Presenteeism, which refers to going to work despite being ill, has been associated with loss of work productivity, decreased quality of care, and an increased risk of health problems. The prevalence of presenteeism is particularly high among nurses; therefore, a reliable and valid tool is needed to assess presenteeism. This study aimed to translate the Stanford Presenteeism Scale (SPS) and to examine its psychometric properties in a Korean nurse population. A methodological study was performed in January 2023. The original SPS-6 (English-language) was translated and adapted to the Korean language using a committee approach translation, cognitive interviews, and content validation with a review panel of experts. An online survey was completed by 608 Korean nurses. The internal consistency, item-to-total correlation, construct validity, concurrent validity, and discriminant validity were examined as psychometric properties of the Korean version of the SPS. The final version of the K-SPS consists of four items shortened from the original six items. Cronbach's alpha of the K-SPS-4 was 0.74, indicating adequate reliability. Confirmatory factor analysis showed a one-factor solution with a good fit. There was a positive correlation between the K-SPS-4 and the Work Limitations Questionnaire. Discriminant validity was evidenced by the positive correlation of the K-SPS-4 with job satisfaction and the negative correlation with job stress. The K-SPS-4 has acceptable psychometric properties, supporting the feasibility of its use in assessing the level of presenteeism among Korean nurses. The validated K-SPS-4 can provide a basis for developing intervention programs to enhance productivity and promote health among nurses in clinical settings.
