Turkish adaptation of the Pelvic Organ Prolapse Symptom Score and its validity and reliability.

INTRODUCTION AND HYPOTHESIS

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.
