Abstract: To adapt and evaluate the psychometric properties of the SUSESO/ISTAS21 questionnaire for nurses in Spain. Cross-sectional study for the cross-cultural adjustment and psychometric validation of the COPSOQ-ISTAS21 scale. Descriptive analyses were conducted, and data was correlated. A confirmatory factor analysis was performed, thus assessing the reliability and criterion validity. The sample consisted of 2757 Spanish nurses. The exploratory factor analysis identified a 5-factor structure with 15 items, which explained 63.6% of the variance. The factors were named: Support at work; Job satisfaction; Work-related emotional well-being; Job insecurity; and Double presence. The internal consistency of the questionnaire, measured by Cronbach alpha and McDonald omega coefficient, was adequate, with values of 0.764 and 0.741, respectively. The results of the confirmatory factor analysis indicated a good model fit. Three levels of psychosocial risk (low, intermediate, and high) were identified based on percentiles and quartiles of mean scores. The adapted version of the SUSESO/ISTAS21 questionnaire showed reliable psychometric properties in Spanish nurses, making it a valid and robust tool for assessing psychosocial risks in this group.
