The Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7) assess symptom distress and the impact on daily life of urinary incontinence. The UDI-6 has not been validated before in males. Our aim was to validate the UDI-6 and IIQ-7 in Dutch men and women.
The translation to Dutch followed standardized procedures. We validated the IIQ-7 with and without an additional gender-neutral item (IIQ-SF). Adults with urinary incontinence for at least 3 months, completed the measures at inclusion; 1-week after inclusion to evaluate the test-retest reproducibility; and 6 months after inclusion with the addition of the RAND-36 health transition item to assess responsiveness and interpretability. To assess the discriminate ability, a reference population was enrolled. To assess construct validity, the urodynamic diagnosis was used.
Questionnaire data of 160 patients were analyzed. Patients reported more symptoms and bother than the reference population (P < 0.001). The internal consistency was good in the IIQ-SF baseline scores (Cronbach's alphas 0.86-0.92), though moderate in the UDI-6 (Cronbach's alphas 0.44-0.66). Both measures showed good reproducibility at the test-retest (Intraclass Correlations Coefficients 0.75-0.85). Construct was adequate with 75% confirmed hypotheses of urodynamic data with measure scores. The measures were responsive after treatment with smaller measurement errors than the minimal important change. No floor or ceiling effects were observed in baseline data.
The Dutch UDI-6 and IIQ-7 are reliable, valid, and responsive instruments for assessing symptom distress of urinary incontinence and its impact on daily life in both men and women.
泌尿生殖系统困扰量表（UDI - 6）和尿失禁影响问卷（IIQ - 7）用于评估症状困扰程度以及尿失禁对日常生活的影响。UDI - 6此前未在男性中进行过验证。我们的目的是在荷兰男性和女性中验证UDI - 6和IIQ - 7。
翻译成荷兰语遵循标准化程序。我们对有或没有一个额外的中性性别项目（IIQ - SF）的IIQ - 7进行了验证。患有尿失禁至少3个月的成年人在纳入时完成这些测量；纳入后1周评估重测信度；纳入后6个月，增加RAND - 36健康转变项目以评估反应度和可解释性。为评估区分能力，纳入了一个参照人群。为评估结构效度，采用了尿动力学诊断。
分析了160例患者的问卷数据。患者报告的症状和困扰比参照人群更多（P < 0.001）。IIQ - SF基线分数的内部一致性良好（克朗巴哈系数0.86 - 0.92），而UDI - 6的内部一致性中等（克朗巴哈系数0.44 - 0.66）。两种测量方法在重测时均显示出良好的信度（组内相关系数0.75 - 0.85）。结构效度良好，75%的尿动力学数据假设与测量分数得到证实。治疗后这些测量方法具有反应度，测量误差小于最小重要变化。在基线数据中未观察到地板效应或天花板效应。
荷兰版UDI - 6和IIQ - 7是评估尿失禁症状困扰及其对男性和女性日常生活影响的可靠、有效且具有反应度的工具。
