Abstract
Objective: To evaluate the reliability and validity of Filipino version of Farhat's Dysfunctional Voiding Symptom Score (DVSS) questionnaire
Materials & Methods: Farhat's DVSS was forward translated to Filipino and back translated to English. The translated questionnaire underwent a pre-test test to 43 patients and evaluated. Then a re-test was done to 60 patients divided into two groups, Group 1 consisted of children with voiding dysfunction and Group 2 consisted of children without voiding dysfunction.
Result: None of the participants in the pre-test answered "I did not understand". The pre-test results had undergone Cronbach alpha with 0.812 and the re-test results' Cronbach alpha was 0.747. A high degree of stability was found with intraclass correlation coefficient (ICC) of 0.747 (p<0.001; 95% CI: 0.639-0.832).
Conclusion: The cross-cultural adaptation process of the DVSS questionnaire to be used on Filipino children was successfully completed. The Filipino version of DVSS is acceptable as an accurate diagnostic tool with cross-cultural variety.
