Urogenital Distress Inventory-6 (UDI-6), Incontinence Impact Questionnaire-7 (IIQ-7) and The International Consultation on Incontinence (ICIQ-SF) Short Form are used to diagnose individuals with urinary incontinence (UI) and to assess the impact of the dysfunction on patient quality of life. While ICIQ-SF has fixed cutoff values-UDI-6 and IIQ-7 do not. We aimed to find the cutoff scores for UDI-6 and IIQ-7 in women with UI.
The study involved 205 women aged between 31 and 83 years-155 with, and 50 without UI symptoms. All participants completed all three questionnaires: ICIQ-SF, UDI-6 and IIQ-7. Patients were categorized according to their ICIQ-SF scores, as symptomatic ICIQ-SF ≥ 6 (n = 134) and asymptomatic ICIQ < 6 (n = 60). The Receiver Operating Characteristics (ROC) curve was used to test how well UDI-6 allowed a discrimination between patients suffering from UI and those who do not. Area under Curve (AUC) statistic was calculated to measure the UDI-6 and IIQ-7 Total Score efficiency.
The cutoff values were selected. On the basis of the ROC curve analysis, the UDI-6 Total Score of 33.33 and IIQ-7 Total Score of 9.52 were determined to be the optimal cutoff for distinguishing between symptomatic and asymptomatic women (AUC = 0.94-UDI-6 and 0.91-IIQ-7).
For UDI-6 scores more than 33.33 indicate higher distress caused by UI symptoms. Moreover, the higher impact of UI on health- related quality of life is seen in women who scored 9 or more in the IIQ-7 questionnaire, and such women felt impaired quality of life.

尿失禁生活质量问卷 6 项简表（UDI-6）、尿失禁影响问卷 7 项简表（IIQ-7）和国际尿失禁咨询问卷简表（ICIQ-SF）用于诊断尿失禁（UI）患者，并评估该功能障碍对患者生活质量的影响。虽然 ICIQ-SF 有固定的截断值，但 UDI-6 和 IIQ-7 没有。我们旨在为 UI 女性确定 UDI-6 和 IIQ-7 的截断评分。
本研究纳入了 205 名年龄在 31 至 83 岁之间的女性，其中 155 名患有 UI 症状，50 名无症状。所有参与者均完成了 ICIQ-SF、UDI-6 和 IIQ-7 这三个问卷。根据 ICIQ-SF 评分将患者分为有症状 ICIQ-SF≥6（n=134）和无症状 ICIQ<6（n=60）。使用受试者工作特征（ROC）曲线测试 UDI-6 区分患有 UI 和未患有 UI 的患者的能力。计算曲线下面积（AUC）统计量以评估 UDI-6 和 IIQ-7 总分的效率。
选择了截断值。基于 ROC 曲线分析，UDI-6 总分为 33.33 分和 IIQ-7 总分为 9.52 分被确定为区分有症状和无症状女性的最佳截断值（AUC=0.94-UDI-6 和 0.91-IIQ-7）。
UDI-6 评分超过 33.33 分表明 UI 症状引起的困扰更大。此外，在 IIQ-7 问卷中得分 9 或更高的女性中，UI 对健康相关生活质量的影响更大，这些女性感到生活质量受损。注册号 NCT04433715，于 2020 年 11 月 6 日“回顾性注册”。
