title: Validation, cultural adaptation and responsiveness of two pelvic-floor-specific quality-of-life questionnaires, PFDI-20 and PFIQ-7, in a Turkish population.
abstract: OBJECTIVE
  The aim of the study was cultural adaptation, validation, and test for responsiveness of the short forms of the Pelvic Floor Distress Inventory (PFDI-20) and the Pelvic Floor Impact Questionnaire (PFIQ-7) in a Turkish population.
  
  
  METHODS
  To evaluate their validity, questionnaires were applied to 248 women. The questionnaires were compared with prolapse stage according to the Pelvic Organ Prolapse Quantification (POP-Q) system. The responsiveness of the questionnaires was assessed in 103 women with prolapse who also completed the questionnaires after reconstructive surgical treatment, with standardized response mean (SRM), effect size (ES), and the Wilcoxon signed-rank test.
  
  
  RESULTS
  Cronbach alpha coefficients of the Turkish PFDI-20 and PFIQ-7 questionnaires were 0.908 and 0.830, respectively. Significant correlations were observed between the scores of the questionnaires with the vaginal examination findings. The PFDI-20 and PFIQ-7 scores were significantly improved after vaginal reconstructive surgery.
  
  
  CONCLUSIONS
  Turkish translated versions of the PFDI-20 and PFIQ-7 are reliable, valid and responsive instruments for assessing symptom severity, impact on QoL in women with pelvic organ prolapse. They can be easily administered and self-completed by Turkish women.
