Abstract

Defecation disorder is one of the main symptoms in pelvic organ prolapse (POP) patients. Our study aims to translate the Chinese version of the constipation scoring system (CSS) questionnaire and test the reliability and validity of its application in Chinese POP women. We recruited 140 women suffering prolapse with stage II or above POP who reported at least one abnormal defecation symptom. We chose CRADI-8 as the criterion validity. Cronbach's α coefficient of the total score of CSS was 0.721, the ICC and Kappa coefficient of CSS total score were 0.877 and 0.424, respectively. The total score of CSS was significantly correlated with the CRADI-8 score (p < 0.001), and Spearman's coefficient was 0.491. The total score of CSS in the women with constipation (according to Rome III criteria) was greater than that of patients without constipation (p < 0.001), and the total score of CSS was significantly different before and after surgery (p < 0.001), which was consistent with the change of CRADI-8. The median of the preoperative group was 6(3,10), and the median of the postoperative group was 3(0,7). These data demonstrate that the Chinese version of the CSS questionnaire has great internal consistency, retest reliability, and construct validity. It may be widely used to evaluate constipation symptoms in women with pelvic organ prolapse in China.
