The aim of this study was to adapt and translate into Portuguese the Conditions for Work Effectiveness Questionnaire (CWEQ-II) (Laschinger, Finegan, Shamian, & Wilk, 2004). A process of translation and reverse-translation was applied to the questionnaire's items, whose psychometric properties were examined using a sample of 282 Portuguese university employees, teachers and services staff. The data were subjected to confirmatory factor analysis, item analysis and reliability analysis. Criterion-related validity was analyzed using a multiple regression model on global empowerment and t-test. The results confirmed the original, four-factor structure obtained by Laschinger and colleagues (2004), supporting Kanter's structural empowerment theory. The psychometric properties of the Portuguese version of the CWEQ-II were adequate, supporting the use of this questionnaire in the workplace. Future research should investigate its construct validity and test the nomological network of the operationalized construct within the field of psychological well-being and in the context of the workplace.
