title: Turkish adaptation of the Pelvic Organ Prolapse Symptom Score and its validity and reliability.
abstract: OBJECTIVE
  The purpose of this study was to adapt the Pelvic Organ Prolapse Symptom Score (POP-SS) into Turkish and evaluate its reliability and validity.
  
  
  METHODS
  The POP-SS was adapted into Turkish by following the steps of the intercultural adaptation process. One hundred and three women with symptomatic or asymptomatic pelvic organ prolapse (POP) completed the Turkish POP-SS and other valid and reliable Turkish tools for POP: Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6), Colorectal-Anal Distress Inventory 8 (CRADI-8), Urinary Distress Inventory 6 (UDI-6), Pelvic Floor Distress Inventory 20 (PFDI-20), and Pelvic Organ Prolapse Impact Questionnaire 7 (POPIQ-7). Pelvic Organ Prolapse Quantification (POP-Q) system was also used to assess pelvic support, and patients were divided into three groups based on POP-Q scores. Cronbach's alpha was used to determine internal consistency, and intraclass correlation coefficient (ICC) was estimated for test-retest reliability. POP-SS validity was assessed by using the Spearman rank correlation and Kruskal-Wallis analyses. The underlying scale structure was determined by exploratory factor analysis.
  
  
  RESULTS
  The POP-SS scale had high internal consistency (Cronbach's alpha = 0.705) and test-retest reliability (ICC = 0.981; p < 0.001). Among groups, there was statistically significant differences in POP-SS scores. POP-SS scores were also significantly correlated with POPDI-6 (r = 0.830), CRADI-8 (r = 0.525), UDI-6 (r = 0.385), PFDI-20 (r = 0.752), and POPIQ-7 (r = 0.690) (p < 0.001). Two factors were identified by exploratory factor analysis.
  
  
  CONCLUSIONS
  The Turkish version of POP-SS is a valid and reliable tool for Turkish women with POP.
