Results: The European Portuguese version of Qualiveen has conceptual and linguistic equivalence, showing an excellent reliability for the total scale (Cronbach’s alpha of .96) and its subdomains (Cronbach’s alpha of .81 and .93), as well as convergent and discriminant validity. Conclusion: The European Portuguese version of Qualiveen showed adequate psychometric properties.
