Introduction: : High prevalence of nocturia and its debilitating nature, addressing the quality of life of patients has always been a serious issue among researcher and health care providers in order to improve the quality of medical care. A few questionnaires have been translated or adapted to evaluate quality of life among those suffering nocturia. The present survey aimed to assess the reliability and validation of the Persian version of the International Consultation on Urinary Incontinence Short Form Questionnaire (ICIQ-NQOL) questionnaire among Iranian women suffering urinary incontinence
Methods: Translation of the Persian version of the ICIQ-NQOL was determined by native Persian and English speakers (including translation and back translation). The content validity was assessed by calculating content validity coefficient ratio (CVR), reliability by test-retest analysis and internal consistency by determining the Cronbach’s alpha coefficient.
Results: Cronbach’s alpha coefficient for ICIQ-NQOL questionnaire was 0.754, indicating a high level of internal consistency without redundancy. For the test–retest reliability analysis, the ICIQ-UI SF had a consistency coefficient of 0.795, indicating acceptable test–retest reliability. The clinical experts agreed that the questionnaires were intelligible and covered all important domains with an overall CVR of 0.93.
Conclusion: The Persian version of the ICIQ-NQOL has high reliability and acceptable validity to assess nocturia among Iranian women
