Aim The purpose of the present study was to translate and validate the Incontinence Quiz (IQ) questionnaire into a Portuguese version. Methods The Portuguese version of the 14‐item Incontinence Quiz was prepared following translation and back‐translation procedures and was tested on a pilot group of 10 women. Internal consistency (Cronbach's α ), test‐retest reliability (intraclass correlation coefficient [ICC]), and construct validity (using two indicators: education level and being a qualified health professional) were assessed in 141 women from the staff of two higher education institutions. Participant's socio‐demographic characteristics were collected by questionnaire. Results The translation and back‐translation process was performed without constraints. Cronbach's α ranged from 0.696 (Item 13) to 0.748 (Item 6), and global Chronbach's α was .740. ICC values for the IQ total score were .78, .57, and .79 for correct, wrong, and do not know answers, respectively. Both economic indicators were positively associated with the percentage of correct answers. Conclusions Validity and reliability of the translated Portuguese IQ were achieved which will allow the comparison of results with studies in other cultures.
