Psychometric validation and cross-cultural adaptation of the Persian ICIQ-CLUTS child module for assessing pediatric lower urinary tract symptoms

Abstract

Background Lower urinary tract symptoms (LUTS) are common in children and significantly affect their physical, emotional, and social well-being. Although older tools exist for assessing LUTS in children, a widely recognized and reliable Persian version has not been developed. This study aimed to translate, adapt, and validate the Persian version of ICIQ-CLUTS for children.<br /> Methods This cross-sectional study followed ICIQ and COSMIN guidelines for translation and adaptation. Fifty-one children aged 9-14 years were included: the case group consisted of children with urinary symptoms, while the control group comprised children with unrelated conditions Children completed the questionnaire twice, with a 7-10 day interval. Psychometric testing included internal consistency (Cronbach's a), test-retest reliability (ICQ, item analysis, discriminant validity, and ceiling/floor effects<br /> Results Gender distribution was 27 females (52.9) and 24 males (47.1), with no significant association between gender and group. Persian ICIQ-CLUTS was highly consistent internally (Cronbach's a = 0.927 ) Test-retest reliability was high (p = 0.913 - 1) , and discriminant validity was determined (p < 0.001) There was no floor and ceiling effect. It was highly feasible and highly acceptable and generated minimal missing data.<br /> Conclusion Persian ICIQ-CLUTS is a valid and reliable questionnaire to screen pediatric LUTS in Persian children. It has good psychometric properties, suitable for clinical application and research. Its treatment responsiveness and long-term effectiveness need to be investigated further
