Workplace dignity scale in Iranian nurses: translation and psychometric evaluation.

Background: Workplace dignity is defined as a person's perception of respect and trust, equal and fair treatment, valuing the person, independence, freedom of expression, and decision-making enjoyed by the employee in the workplace. Therefore, this study aimed to develop the Workplace Dignity Scale (WDS) and evaluate its psychometric properties.

Methods: In this methodological study, WDS was translated based on Beaton et al. Guideline. After assessing face and content validity (using CVI, CVR, modified kappa, and item impact), 250 nurses were selected by random sampling from Kashan hospitals in 2023. Then, WDS was assessed through expletory factor analysis (EFA), known-groups comparison, internal consistency, and stability. The ceiling and floor effects were also examined. Data were analyzed using SPSS v16 by Kruskal-Wallis test, Cronbach's alpha, McDonald's Omega, interclass correlation coefficient (ICC), standard error of measurement (SEM), and minimum detectable changes (MDC).

Results: The scale's CVI, CVR, and modified kappa were above 0.79. Item impact was higher than 1.5. EFA extracted three factors, including "general dignity, respect, and indignity", that could explain 70.6% of the total variance in scale. WDS could differentiate between the three groups in terms of occupation satisfaction status. Cronbach's alpha, McDonald's Omega, ICC, SEM, and STC of scale were 0.949, 0.950, 0.970, 2.793, and 7.742, respectively.

Conclusion: The Persian version of the WDS has shown validity and reliability for measuring workplace dignity among nurses in the Iranian context.
