The use of consultation on Incontinence Questioner – Nocturia (ICIQ-N) in Indonesian population: an affirmation study

Abstract

Background: Nocturia is a urological condition in which individuals urinate more frequently than usual at night and it affects both genders. The clinician frequently uses questionnaires to diagnose nocturia however, some validated questions were in English. This study evaluated the validity of the International Consultation on Incontinence Questionnaire – Nocturia (ICIQ-N) in Indonesian patients. Methods: Two certified bilinguals (English-Indonesian) translated the ICIQ-N questionnaire from English to Indonesian. The reverse translation was done by two certified bilingual (Indonesian-English) translators, and the writers reviewed all of the translations leading to the final Indonesian translation. Instead of a linguistic translation, this technique ensured a thorough and unambiguous intellectual translation. The translated ICIQ-N was presented twice to the subjects, two weeks apart, to verify the questionnaire. The responses' validity and reliability were then investigated. Pearson and Cronbach’s alpha analysis were used to determine validity and reliability. Results: The r-Pearson correlation values ranged from 0.933 to 1 (p:0.001). The translated ICIQ-N questioner items were found to be reliable with a Cronbach's alpha of 0.994 (>0.6). Conclusions: The ICIQ-N Indonesian version generated for this study is valid and reliable. As a result, it may be utilized as a diagnostic tool in Indonesian population.
