Validation of Serbian Version of Dysfunctional Voiding Symptom Score (DVSS) Questionnaire.

ABSTRACT: OBJECTIVE:The aims of our study were to translate the dysfunctional voiding symptom score (DVSS) from English to Serbian; culturally adopt the items; assess the internal consistency and the test?retest reliability of DVSSSR in patients with dysfunctional voiding (DV); evaluate and test the construct and divergent validity of DVSSSR against demographic parameters (gender and education); and examine the level of explained variability for each item of DVSSSR against demographic parameters (gender and education). METHODS:The cross-sectional observational study included 50 patients with dysfunctional voiding aged 5 years and above. The DVSS questionnaire was translated from English into Serbian by the forward?backward method. Internal consistency was assessed with Cronbach ? and test?retest reliability with intraclass correlation coefficient (ICC). For validity testing we performed construct and divergent validity analyses. RESULTS:There was excellent internal consistency for every item except for Item 6 (0.787) and Item 3 (0.864), where internal consistency was good. The observed test/retest ICC for average measures was more than 0.75 (excellent) for all DVSSSR items. Gender and educational level does not correlate significantly with each item of DVSSSR (p > 0.05). For divergent validity, there were no significant differences in mean values of each item of DVSSSR between genders and different levels of education (p > 0.05). Variability that can be explained for gender and educational level was below 10%. CONCLUSION:Translated DVSSSR is of adequate validity and reliability for assessing DV in children.

Project description:BackgroundBoth for clinical and research purposes, it is critical that clinicians and researchers use a tool that is trans-culturally adapted and tested for its psychometric properties. The English version of the Pelvic Organ Prolapse Symptom Score (POP-SS) questionnaire was developed in 2000. Since then it has been translated into other languages and verified. However, the tool has not been adapted for use in Sidaamu Afoo language in the Sidama Region of Ethiopia.ObjectiveThis study aimed to translate and adapt the Pelvic Organ Prolapse Symptom Score questionnaire into Sidaamu Afoo and evaluate its psychometric properties.MethodsA total of 100 women with symptomatic prolapse completed version-2 of the POP-SS questionnaire during the first round of interviews, and 61 of them completed the questionnaire during the second round of interviews (to establish the test-retest reliability). We adapted the scale translation process recommended by Beaton and his colleagues. The content validity was assessed using the content validity index and the construct validity was done based on exploratory factor analysis using the principal component analysis model. The criterion validity was evaluated by using the Kruskal-Wallis test based on stages of the prolapse established via pelvic examination. The internal consistency reliability of the scale was assessed using Cronbach's alpha value, and test-retest reliability was evaluated using the intraclass correlation coefficient.ResultsThe questionnaire was successfully translated to Sidaamu Afoo, and achieved a good content validity index (0.88), high internal consistency (Cronbach's alpha of 0.79), and test-retest reliability (an intraclass correlation coefficient of 0.83). The exploratory factor analysis revealed two factors based on an eigenvalue of 1. The two factors explained 70.6% of the common variance, and each item loaded well (0.61 to 0.92) to its corresponding factor. There is a significant difference in the median score of prolapse symptoms across different stages of prolapse (Kruskal-Wallis χ2, 17.5, p < 0.001).ConclusionThe Sidaamu Afoo version of the POP-SS tool is valid and reliable. Further studies that involve a balanced number of women in each stage of prolapse are needed to avoid the ceiling and floor effects.
