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 α 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.

Validation and Cultural Adaptation of the Serbian Version of the Pediatric Outcome Data Collection Instrument (PODCI) in Children with Obstetrical Brachial Plexus Lesion

“…For the adequate process of transcultural adaptation, we aimed to follow idiomatic and semantic equivalence [16] between the original and translated PODCI versions. It should be stressed that transcultural adaptations are complex and sensitive, especially for the purpose of the validation of standardized questionnaires, thus scientists and collaborators should aim to preserve the sensitivity of items and domains [17]. For proper adaptation of the testing instrument, several aspects regarding translation should be taken into consideration, including cultural, idiomatic, linguistic and contextual aspects [18].…”

Cross-Cultural Adaptation and Quantitative Evaluation of Dysfunctional Voiding and Incontinence Scoring System in Pediatric Serbian Population

“…There was no feedback regarding difficulties in item interpretation and answering during the debriefing step. The expert panel that consisted of two independent pediatric urologists and one independent physiatrist with subspecialist interests in voiding dysfunctions [8] was invited for the final debate and the Serbian version of DVISS 3.0 was approved as the final form (DVISS SR ).…”
