Abstract

The International Consultation on Incontinence Questionnaire-Pediatric Lower Urinary Tract Symptoms (ICIQ-CLUTS) is a 12-item self-administered tool to screen lower urinary tract symptoms (LUTS) in children. The aim of this study is to translate and validate the ICIQ-CLUTS into Spanish (ICIQ-CLUTS-Sp) and to study its psychometric properties. The cross-cultural adaptation of the ICIQ-CLUTS was performed following international recommendations. The psychometric analysis of the ICIQ-CLUTS-Sp was carried out to determine the reliability, validity, and diagnostic accuracy in a sample of 155 children and parents who completed the Spanish version ICIQ-CLUTS. The reliability indicators for the ICIQ-CLUTS-Sp were excellent (Cronbach's alpha was > 0.8 and ICC > 0.9 both for children's and parents' versions). There was a high Pearson r > 0.6 and a high agreement level between children's and parents' answers (ICC > 0.6), except in 4 items. For parents, the standard error of measurement (SEm) was 0.41, and the minimal detectable change (MDC) was 1.14 points. In children, these results were 0.42 and 1.16 points, respectively. Cut-off points greater than 15 points in the parent version or 16 points in the children version have the highest sensitivity and specificity for detecting LUTS. Conclusion: The Spanish version of the ICIQ-CLUTS questionnaire is a valid, reliable, and diagnostically accurate instrument to identify cases of children with LUTS. Therefore, it can be used to screen for lower urinary tract symptoms in Spanish speaking children and/or parents, as well as to monitor the effects of interventions. What is Known: • Lower urinary tract symptoms in children should be assessed multimodally using minimally invasive diagnostic procedures. One way to do this is to use the questionnaire to differentiate these cases in paediatric patients. • A cross-cultural adaptation of the ICIQ-CLUTS questionnaire to Spanish has not yet been done. What is New: • Based on a comprehensive validation methodology, this study highlights that the ICIQ-CLUTSSp questionnaire has good psychometric properties.
