Psychometric validation of the Taiwanese nurse burnout scale

Nurse burnout has a negative impact on nurse retention, well-being, and the quality of patient care. The differences in healthcare systems and cultures also lead to the differences in perceptions of nurses burnout. The aim of this study was to evaluate the validity and reliability of the nurse burnout scale, a context-specific instrument for Taiwanese nurses. This methodological study was conducted in three medical centers across Taiwan using secondary data from a National Science Council project. The Taiwan Nurse Burnout Scale (TNBS) was developed through literature review, qualitative interviews, expert validation, and pilot testing. Psychometric evaluation included exploratory and confirmatory factor analyses to assess construct validity, and reliability. Data were analyzed using SPSS and JASP to ensure the scale’s validity and reliability for assessing burnout among Taiwanese clinical nurses. The sample size of the final analytic sample was 529 nurses who were recruited in three medical Centers in Taiwan. A nine-factor and 42-item version of the Taiwanese Nurse Burnout Scale (TNBS) did not demonstrate the best fit indices in the confirmatory analysis, which led to the accounting of an alternative structural model. Exploratory factor analysis (EFA) of the revised scale resulted in a five-factor, 19-item solution that explained 73.2 per cent. of the total variance. A following confirmatory factor analysis (CFA) indicated acceptable fit, where the standardized loadings ranged between.58 to.95, average variance extracted (AVE) ranged between 0.58 and.85, the composite reliability was between.85 and. 94 and the Cronbach’s α 0.92 of the entire scale, thus validating the construct validity and reliability of the instrument. The five-dimensional, 19-item Taiwan Nurse Burnout Scale (TNBS) is indicated to have a strong psychometric face, thus making it an effective and reliable tool in the evaluation of burnout among Taiwanese clinical nursing groups.
