Psychometric Properties of the Chinese Version of the Gratitude at Work Scale in Employed Nurses: A Cross-Sectional Study.

Abstract

The Gratitude at Work Scale, originally developed by American scholars, has been widely administered to mental health professionals and human service workers to explore gratitude in the workplace. No Chinese-language instrument is currently available for assessing workplace gratitude. The aims of this study were to (a) translate the original English version of the Gratitude at Work Scale into a traditional Chinese version (TC-GAWS), confirm its factor structure, and analyze its psychometric properties among newly employed nurses and (b) develop and evaluate the psychometric properties of the TC-GAWS short form. A psychometric study using a cross-sectional web-based design was conducted in Taiwan. Three hundred twenty-two employed nurses completed a battery of self-administered online questionnaires that included a demographic datasheet, the Gratitude Questionnaire-Six-Item Form, the Connor-Davidson Resilience Scale-10, and the Thoughts of Quitting Scale. IBM SPSS 24.0 and AMOS 28.0 were used for data analysis, and Cronbach's alpha and Pearson's correlation were used to assess reliability and concurrent validity. Exploratory factor analysis and confirmatory factor analysis (CFA) were conducted. The internal consistency and stability of the TC-GAWS total scale were .88 and .91, respectively. The exploratory factor analysis showed a satisfactory Kaiser-Meyer-Olkin value of .88 and a Bartlett's test value of 654.01 (p < .001), suggesting that 64.55% of the total variance was explained by the two-factor TC-GAWS. After item reduction, the CFA of the six remaining items of the TC-GAWS short form revealed adequate fit statistics for a two-factor structure and a second-order factor. Strong correlations were found between the 10-item and six-item TC-GAWS (r > .94) in the two samples, suggesting good concurrent validity. The overall scores for the 10-item and six-item TC-GAWS had similar convergent validity, with moderate-to-strong correlations for the Gratitude Questionnaire-Six-Item Form (r = .45 and .540), Connor-Davidson Resilience Scale-10 (r = .49 and .51), and Thoughts of Quitting Scale (r = -.57 and -.53). The CFA yielded a two-factor, six-item model that exhibited good fit with the latent constructs of χ2/df = 11.06/8 = 1.38, p = .198, comparative fit index = .996, goodness-of-fit index = .979, root mean square error of approximation = .045, root mean square residual = .030, and standardized root mean squared residual = .023. Both the 10- and six-item TC-GAWS instruments demonstrated good reliability and validity in nurse participants. The TC-GAWS may be used to measure gratitude in nurses in the workplace. This instrument has the potential to facilitate a better understanding of gratitude in nurses, which may be applied to the improvement of nursing management, research, and education.
