Abstract

Background: The Dysfunctional Voiding Score Symptoms (DVSS) questionnaire is commonly used to evaluate dysfunctional voiding and incontinence (DVI). Objectives: To translate and culturally adapt the DVSS questionnaire into Spanish (DVSS-Sp) in pediatric population and to assess its psychometric properties. Methods: The process of translation and cultural validation were done. To obtain evidence of validity and reliability, we evaluated the fit of different factor models and calculated internal consistency coefficients. Also, the diagnostic capacity of the DVSS-Sp scale was assessed through a logistic regression analysis and a receiver operating characteristic (ROC) curve. Accordingly, a total sample of 248 participants was recruited (204 with a diagnosis of DVIs and 44 with no medical problems). Results: The cross-cultural adaptation showed an adequate correspondence with the original version. The DVSSSp was configured with 2 factors: Overactive Bladder (OB) symptoms (items 1, 2, 6, and 7) and Dysfunctional Elimination (DE) symptoms (items 3, 4, 8, and 9), showing excellent goodness-of-fit indices. The relationship between the factors OB and DE was low. The reliability of the OB factor was alpha = 0.68, omega = 0.71, and the DE factor was alpha = 0.56, omega = 0.57. A logistic regression analysis suggests a good diagnostic capacity of the DVSS-Sp scale. Additionally, ROC analysis showed a cut-off score of 3.5 on the DVSS-Sp scale, where the specificity was 0.907, and the sensitivity was 0.636. Conclusion: The results of this study support the use of the DVSS-Sp for assessing DVIs in Spanish-speaking children.
