AB  - PURPOSES: To evaluate the reliability and validity of a Korean version of the
      Functional Assessment of Cancer Therapy (FACT)-Vanderbilt Cystectomy Index (VCI) 
      in Korean patients who underwent radical cystectomy (RC) and urinary diversion
      (UD). MATERIALS AND METHODS: We prospectively recruited 108 RC and UD patients
      who did not have evidence of recurrence from 1994 December to 2015 March. All
      participants were instructed to complete the Korean FACT-VCI and Short-Form
      36-Item Health Survey (SF-36; 1st measurement) and to repeat the Korean FACT-VCI 
      survey one month later (2nd measurement). Statistical analysis included
      intraclass correlation, Cronbach's alpha, time and UD type fixed mixed linear
      model, principal components analysis, and criterion-related validity with SF-36. 
      RESULTS: Korean FACT-VCI was internally consistent (alpha = 0.802) and had
      adequate test-retest reliability (interclass correlation = 0.803 and 0.822). The 
      three components model of principal component analysis (cumulative explanatory
      power, 49.2%) confirmed the internal structural validity of the additional
      concerns (AC) component of the Korean FACT-VCI, and each component represented
      the "voiding problem", "bowel problem", and "social/functional problem with
      equivalent explanatory power (19.5%, 15.4%, and 14.4%). Korean FACT-VCI domain
      scores were generally well correlated with SF-36 domain scores (Pearson
      correlation coefficients range: 0.286-0.688; all p <0.01). Mixed linear models
      revealed that the major effect of measurement times was not significant on
      FACT-VCI (p = 0.589). CONCLUSIONS: This prospective study confirms the
      reliability and validation of the Korean FACT-VCI. We expect that this validated 
      tool can be widely utilized in the health-related quality of life studies of
      Korean patients.
