title: Development and validation of the Korean version of the Female Sexual Function Index-6 (FSFI-6K).
abstract: OBJECTIVE
  To evaluate the validity and reliability of the Korean version of the Female Sexual Function Index-6 (FSFI-6K).
  
  
  METHODS
  Participants were recruited from February 2013 to July 2013. The primary survey was conducted for 220 participants, and a follow-up was conducted 3 weeks (±1 week) after the primary survey. The FSFI-6K data were analyzed and compared to the reference values in the original FSFI.
  
  
  RESULTS
  Of the 220 participants, 199 (90.5%) returned to follow-up, 18 (8.2%) had no further contact, and 3 (1.4%) declined to respond. The internal consistency of the FSFI-6K as measured by Cronbach's alpha was 0.888 and the reliability based on test-retest intraclass correlation was 0.606; these values were acceptable. The cutoff used for diagnosis of female sexual dysfunction by an receiver operating characteristics (ROC) curve was a score of 21; the sensitivity and specificity for this curve are 0.89 and 0.86, respectively. The area under the receiver operating curve was 0.948.
  
  
  CONCLUSIONS
  The FSFI-6K has high internal consistency and acceptable reliability. This validated questionnaire can be used for the Korean population.
