We aimed to assess the validity and reliability of two Danish versions of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) in a female population. We hypothesized that the questionnaires had good predictive validity, internal consistency, patient-physician agreement, construct validity, test-retest reliability, and sensitivity to change.
To test the predictive validity, we compared the ICIQ-UI SF to urodynamics (n = 153). The same answers were used for testing the internal consistency. The patient-physician agreement was assessed by comparing the self-administered questionnaire with a physician's evaluation based on telephone interviews (n = 60). To test the construct validity, we calculated the proportion of scores ≥ 1 in questionnaires completed by women defining themselves as "not suffering from involuntary urination" (n = 69). Test-retest reliability was assessed by comparing questionnaires completed twice with an interval of 2 weeks (n = 186). Sensitivity to change was evaluated by analyzing answers before and after treatment for women treated surgically for stress urinary incontinence (n = 755) and with botulinum type A toxin for overactive bladder (n = 63).
Predictive validity: 26.6-27.6% agreement. Internal consistency: Cronbach's alpha: 0.7-0.8. Patient-physician agreement: 53.9-92.9% agreement. Some interview participants misunderstood the word "leak." Construct validity: 19% and 23% had a total score ≥ 1. Test-retest reliability: 77.0-95.7% agreement. Sensitivity to change: Significantly lower score after treatment.
The ICIQ-UI SF had excellent internal consistency, patient-physician agreement, test-retest reliability, and sensitivity to change. The ICIQ-UI SF had questionable predictive validity and construct validity compared to urodynamic testing. We recommend precaution in diagnostics or research based solely on the questionnaire.
我们旨在评估两种丹麦版国际尿失禁咨询问卷-尿失禁简短问卷（ICIQ-UI SF）在女性人群中的有效性和可靠性。我们假设问卷具有良好的预测效度、内部一致性、医患一致性、结构效度、重测信度和对变化的敏感性。
为了测试预测效度，我们将 ICIQ-UI SF 与尿动力学（n=153）进行了比较。内部一致性测试使用相同的答案。通过比较自我管理问卷和医生基于电话访谈的评估来评估医患一致性（n=60）。为了测试结构效度，我们计算了自我定义为“不遭受无意识排尿”的女性问卷得分≥1 的比例（n=69）。通过比较间隔 2 周的两次问卷（n=186）评估重测信度。通过分析接受手术治疗压力性尿失禁（n=755）和接受肉毒杆菌 A 毒素治疗膀胱过度活动症（n=63）的女性治疗前后的答案来评估对变化的敏感性。
预测效度：26.6-27.6%的一致性。内部一致性：克朗巴赫α：0.7-0.8。医患一致性：53.9-92.9%的一致性。一些访谈参与者误解了“漏”这个词。结构效度：19%和 23%的总分≥1。重测信度：77.0-95.7%的一致性。对变化的敏感性：治疗后得分显著降低。
ICIQ-UI SF 具有良好的内部一致性、医患一致性、重测信度和对变化的敏感性。与尿动力学检查相比，ICIQ-UI SF 的预测效度和结构效度存在疑问。我们建议在基于问卷的诊断或研究中要谨慎。
