Previous research has highlighted the importance of workplace fun in enhancing employee satisfaction and performance, particularly in high-stress professions like nursing. However, a notable gap exists in understanding how workplace fun is perceived and measured among nurses in Persian-speaking countries. This study addresses this gap by translating the Workplace Fun Scale and assessing its psychometric properties among nurses. The findings will provide insights into the scale's applicability in these contexts and pave the way for healthcare organizations to significantly explore ways to enhance nurses' enjoyment of work in Persian-speaking countries. This survey, which involved 321 nurses from medical education centers in Ardabil, was conducted with a meticulous and rigorous methodology. Standard questionnaires collected the data, including a demographic form and the translated Workplace Fun Scale. The study examined the three aspects of workplace fun: fun activities, coworker socializing, and manager support for fun. Confirmatory factor analysis was used to validate the structure, and reliability was assessed through retest coefficients, Cronbach's alpha coefficients, and composite reliability coefficients. The data were analyzed using SPSS version 14 and LISREL version 8.8, ensuring the highest research standards. The validity of both form and content was confirmed through translation and reverse translation. The Workplace Fun Scale showed high internal consistency and reliability, with significant Cronbach's alpha coefficients, composite reliability, and two-week retest coefficients of 0.859, 0.885, and 0.459, respectively (all at the p < 0.01 level). Fit indices, including GFI (0.97), AGFI (0.94), CFI (0.99), NFI (0.98), TLI (0.97), and SRMR (0.04), indicated a good fit of the measurement model, confirming the validity of the scale in assessing workplace fun. The confirmatory factor analysis results indicated that the translated version of the workplace fun scale, adapted from Tews, exhibited a robust factor structure and internal homogeneity within the Iranian sample. Furthermore, the scale demonstrated positive internal validity and reliability in Persian translation. These findings suggest that the scale possesses acceptable psychometric properties, making it a valuable tool for assessing workplace fun among nurses in Persian-speaking countries.
