Urology - Original Paper



The aim of the current study was to perform the translation, cross-cultural adaptation and validation of the Underactive Bladder Questionnaire (UAB-q).


The study design included the Portuguese translation, cross-cultural adaptation and validation of the UAB-q in 90 patients from a urology outpatient clinic following international methodology. The psychometric properties tested were the validity, reliability, internal consistency and stability of the instrument.


The content validity index at the item (I-CVI) and scale level (S-CVI) were above 0.80 and did not require changes. Regarding the reliability analysis, Cronbach’s alpha was 0.79. The internal consistency and the base time stability (test–retest) had excellent indexes; all were above 0.90.


These results indicate that the UAB-q is a valid, reproducible and reliable instrument for screening underactive bladders and is a potentially useful tool to guide health actions and improve the care of underactive patients.
