title: Reliability and Validation of the International Consultation on Incontinence Questionnaire in Over Active Bladder to Persian Language.
abstract: OBJECTIVE
  Overactive bladder syndrome is a common syndrome in the world in both men and women. Correct diagnosis and accurate measurement of symptoms severity and also quality of life of patients is necessary to ensure proper treatment and to facilitate sound relationships among patients, researchers and doctors. The International Consultation on Incontinence Questionnaire in Over Active Bladder (ICIQ-OAB) questionnaire is a concise and strong tool to evaluate the symptoms of OAB and their effects on patients' quality of life and treatment results. The objective of this study was to translate and validate a simple and strong tool that could be used in clinics and research.
  
  
  METHODS
  First, the original British English questionnaire was translated into Persian by two bilingual and originally Persian-speaking translators. Then the Persian version was back translated to English and a native English speaker studied and compared the questionnaire with the original version. At the end, the translated and corrected Persian version was finalized by a research team. Content validity of the items and ensuring that the questions could convey the main concept to readers was assessed through Modified Content Validity Index (MCVI). Reliability was calculated by Cronbach's α coefficient. Internal Consistency of the questionnaire with the calculation of Kendall correlation coefficient were evaluated by performing test-retest in 50 participants.
  
  
  RESULTS
  The modified content validity index was > 0.78 for all of the questions. Cronbach's α coefficient was calculated 0.76 for all of the participants. Kendall correlation coefficient was calculated for test-re-test assessment 0.66. Both of which indicates the reliability of this questionnaire.
  
  
  CONCLUSIONS
  Persian version of ICIQ-OAB questionnaire is a simple and strong tool for research, treatment and screening purposes.
