Resumo

Objective The aims of this study were to perform a cross-cultural adaptation of the Vulvovaginal Symptoms Questionnaire (VSQ) into Brazilian Portuguese (VSQ-Br) and evaluate its measurement properties (structural validity, construct validity, internal consistency, and reliability). Methods Cross-cultural adaptation was conducted through the translation, synthesis, and back-translation of the VSQ-Br. Subsequently, 314 women completed the Pelvic Floor Impact Questionnaire, Pelvic Floor Disorders Inventory, Medical Outcomes Study 36-Item Short-Form Health Survey, and VSQ-Br. Seven to 10 days later, participants completed the VSQ-Br for the second time. Data were submitted for confirmatory factor analysis. Cronbach alpha was used to verify internal consistency, and construct validity was assessed using Pearson correlation coefficient (r). Reliability was calculated using the intraclass correlation coefficient. Results Confirmatory factor analysis showed that the questions were grouped into four domains (symptoms, emotions, life impact, and sexual impact). The model showed good fit (>0.95). The Cronbach alpha in this study was 0.85, reflecting adequate internal consistency. Adequate reliability was confirmed, with an intraclass correlation coefficient total score of 0.80. The VSQ-Br had a weak correlation with the pelvic domain of the Pelvic Floor Disorders Inventory, the pelvic organ prolapse domain of the Pelvic Floor Impact Questionnaire, and pain, vitality, and the social aspect domains of the Medical Outcomes Study 36-Item Short-Form Health Survey. Conclusions The VSQ-Br was validated and had acceptable measurement properties for assessing vulvovaginal symptoms in Brazilian women. (AU)
