The high prevalence of pelvic floor disorders in women requires assessments using validated instruments. We aimed to translate, cross-culturally adapt to Brazilian Portuguese, and analyze the measurement properties of the International Consultation on Incontinence Questionnaire Vaginal Symptoms Module (ICIQ-VS-Br).
Participants were Brazilian women older than 18 years presenting vulvovaginal symptoms according to the Vulvovaginal Symptoms Questionnaire (VSQ-Br). The development of the ICIQ-VS-Br included the steps of translation, synthesis, back-translation, expert meeting, and pre-test. We analyzed construct validity by correlating the ICIQ-VS-Br and VSQ-Br. The participants answered the ICIQ-VS-Br the second time 7 to 10 days after the first response. We measured test-retest reliability using intraclass correlation coefficient (ICC), internal consistency using Cronbach's alpha, and construct validity using Pearson's correlation coefficient.
The study included 313 women. Reproducibility was analyzed for the three subscales of the ICIQ-VS-Br, resulting in an ICC of 0.92 (95% CI 0.89 to 0.94) for "vaginal symptoms," 0.85 (95% CI 0.78 to 0.89) for "sexual matters," and 0.87 (95% CI 0.81 to 0.91) for "quality of life." Construct validity showed a moderate correlation between ICIQ-VS-Br and VSQ-Br, confirming our hypotheses.
The ICIQ-VS-Br demonstrated validity and reproducibility, indicating that the instrument can be used in scientific research and clinical practice.
女性中盆底功能障碍的高发率需要使用经过验证的工具进行评估。我们旨在将国际尿失禁咨询委员会问卷阴道症状模块（ICIQ-VS-Br）翻译、跨文化适应为巴西葡萄牙语，并分析其测量特性。
参与者为根据阴道症状问卷（VSQ-Br）出现外阴阴道症状的 18 岁以上巴西女性。ICIQ-VS-Br 的开发包括翻译、综合、回译、专家会议和预测试步骤。我们通过将 ICIQ-VS-Br 与 VSQ-Br 相关联来分析结构有效性。参与者在第一次回答后 7 至 10 天内第二次回答 ICIQ-VS-Br。我们使用组内相关系数（ICC）测量重测信度，使用 Cronbach's alpha 测量内部一致性，使用 Pearson 相关系数测量结构有效性。
该研究包括 313 名女性。ICIQ-VS-Br 的三个子量表的可重复性进行了分析，结果阴道症状的 ICC 为 0.92（95% CI 0.89 至 0.94），性问题为 0.85（95% CI 0.78 至 0.89），生活质量为 0.87（95% CI 0.81 至 0.91）。结构有效性表明 ICIQ-VS-Br 与 VSQ-Br 之间存在中度相关性，证实了我们的假设。
ICIQ-VS-Br 具有有效性和可重复性，表明该工具可用于科学研究和临床实践。
