目的：本研究的目的是检验尿失禁影响问卷（IIQ-7）的效度和信度，IIQ-7是一种由7个项目组成的自我报告工具，旨在评估男性尿失禁（UI）的影响。研究对象：58名根治性前列腺切除术后尿失禁的男性为研究对象。方法：由专家小组评估内容效度。在一项比较盆腔肌肉锻炼与盆腔肌肉锻炼加电刺激的随机对照试验中，对三组患有尿失禁的男性进行结构和标准效度检验。确定了IIQ-7的内部一致性和稳定性系数。结果：内容效度指数为0.88。有4项低于指定的内容效度指标水平。一个双因素分析解决方案（因素i -对日常活动的影响；因素ii -情绪影响）解释了84.94%的方差。在UI的影响上没有记录到显著的组间差异（F = 0.37, P = 0.70），受试者之间也没有发现任何随时间的差异（F = 0.90, P = 0.50）。24小时尿垫试验中尿丢失克数与IIQ-7评分呈正相关(r = 0.34, P = 0.003 ~。51, p =.001)。当IIQ-7得分下降时，根据欧洲癌症研究和治疗组织生活质量问卷第2版测量，自我报告的生活质量得到改善（r = -0.57, P = 0.0001至- 0.49,P =.001）。对“泄漏是否影响你的生活？”这一问题的回答与iq -7得分之间存在很强的关系。内部一致性在0.88到0.92之间。进入研究后16至24周，尿量稳定时，IIQ-7评分一致（r = 0.89, P = 0.0001）。结论：IIQ-7是衡量UI影响的可靠指标；然而，该量表需要对男性的结构效度进行额外的测试。
OBJECTIVE: The objective of this study was to test the validity and reliability of the Incontinence Impact Questionnaire (IIQ-7), a 7-item self-report instrument designed to assess the impact of urinary incontinence (UI), in men.SUBJECTS: Fifty-eight men with incontinence after radical prostatectomy were the subjects of the study.METHODS: Content validity was assessed by a panel of experts. Construct and criterion validity were examined with 3 groups of men who had UI in a randomized controlled trial comparing pelvic muscle exercises with pelvic muscle exercises plus electrical stimulation. Internal consistency and stability coefficients for the IIQ-7 were determined.RESULTS: The content validity index was 0.88. Four items were below the designated content validity index level. A 2-factor analysis solution (factor I-impact on daily activities; factor II-emotional impact) explained 84.94% of the variance. No significant group differences were recorded on impact of UI (F = 0.37, P =.70), nor were any differences among subjects found over time (F = 0.90, P =.50). A positive relationship was found between grams of urine loss on a 24-hour pad test and IIQ-7 scores (r = 0.34, P =.003 to.51, P =.001). When the IIQ-7 score decreased, self-reported quality of life improved as measured by the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Version 2 (r = -0.57, P =.0001 to -.49, P =.001). A strong relationship was found between responses to the question "Does leakage affect your life?" and the IIQ-7 scores. Internal consistency ranged between 0.88 and 0.92. IIQ-7 scores were consistent when urine loss was stabilized between 16 and 24 weeks after entry into the study (r = 0.89, P =.0001).CONCLUSION: The IIQ-7 is a reliable measure of the impact of UI; however, the scale requires additional testing regarding construct validity in men.
