International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) is a simple and effective questionnaire for evaluating vaginal symptoms, sexual problems and the quality of life (QOL) in patients. This study was aimed at validating the simplified Chinese version of the ICIQ-VS.
A total of 120 women with pelvic organ prolapse (POP) stage <2, 124 with stage ≥ 2, and 51 patients who underwent POP surgery (POP stage ≥2) were included. Cronbach's alpha coefficient and intraclass correlation coefficient (ICC) were used for reliability analysis. We used the content validity index, Kruskal-Wallis H test, and Mann-Whitney U test to study validity. Paired sample t test, Wilcoxon signed-rank test, effect size and standardized response mean were used to assess sensitivity.
The Cronbach's alpha coefficients of the vaginal symptoms score (VSS) and sexual matters score (SMS) were 0.787 and 0.861 respectively. The test-retest reliabilities of the VSS, SMS, and QOL score were 0.830, 0.894, and 0.948 respectively. The test-retest reliability was from good to excellent (ICC 0.669-0.948). The item-level content validity index was 0.60 to 1.00. The scale-level content validity index/universal agreement was 0.95, and the scale-level content validity index/average was 0.96. Significant score differences existed between the symptomatic and asymptomatic groups (p < 0.001). Criterion validity was significant (p < 0.001). VSS and QOL score had high sensitivity (p < 0.001, effect size and standardized response mean >0.8).
The simplified Chinese version of the ICIQ-VS can objectively and reliably access vaginal symptoms, sexual matters, and QOL in Chinese women.
国际尿失禁咨询问卷-阴道症状（ICIQ-VS）是一种简单有效的问卷，用于评估阴道症状、患者的性问题和生活质量（QOL）。本研究旨在验证简化中文版 ICIQ-VS。
共纳入 120 例盆腔器官脱垂（POP）分期<2 的女性、124 例 POP 分期≥2 的女性和 51 例行 POP 手术（POP 分期≥2）的患者。采用克朗巴赫α系数和组内相关系数（ICC）进行信度分析。我们采用内容效度指数、Kruskal-Wallis H 检验和 Mann-Whitney U 检验进行有效性研究。采用配对样本 t 检验、Wilcoxon 符号秩检验、效应量和标准化反应均值评估敏感性。
阴道症状评分（VSS）和性问题评分（SMS）的克朗巴赫α系数分别为 0.787 和 0.861。VSS、SMS 和 QOL 评分的重测信度分别为 0.830、0.894 和 0.948。重测信度为良好至优秀（ICC 0.669-0.948）。项目水平内容效度指数为 0.60 至 1.00。量表水平内容效度指数/通用一致性为 0.95，量表水平内容效度指数/平均为 0.96。有症状组和无症状组之间的评分差异有统计学意义（p<0.001）。标准效度有统计学意义（p<0.001）。VSS 和 QOL 评分具有较高的敏感性（p<0.001，效应量和标准化反应均值>0.8）。
简化中文版 ICIQ-VS 可客观、可靠地评估中国女性的阴道症状、性问题和 QOL。
