目的：验证评价丹麦老年人群夜间排尿、遗尿和睡眠中断的新问卷。方法：查阅文献和专家共识，编制夜间排尿、遗尿和睡眠中断问卷(NNES-Q)。该问卷是一个更大的问卷的子集，包括几个关于健康状况和排尿的领域。对年龄在60-80岁之间的2000名男性和2000名女性的未经选择的人群进行了会聚和歧视性有效性评估。为了测试重复性，400名受访者被间隔两周邮寄了一份单独的问卷。结果：共有2825人(70.6%)填写了调查问卷。健康状况的下降与烦恼的增加相关(范围从-0.25%到-0.36%，p<；0.001，Spearman‘s r)。这些发现表明可以接受的收敛效度。在不同的症状严重程度组(P<；0.0001，Kruskal-Wallis检验)中位数kappa为0.70(范围0.58-0.86)，表明在重测分析中基本一致。调查问卷中夜尿发作次数与频数相关(Spearman‘s Rho0.88；P<；0.001)。结论：NNES-Q具有较好的区分度和收敛效度，且随时间推移有较好的可靠性。NNES-Q可能在流行病学研究中有用，也可能在夜尿症和夜间遗尿症患者的日常临床工作中具有潜力。(C)2006爱思唯尔B.V.保留所有权利。
Objectives: To validate a new questionnaire evaluating nocturia, nocturnal enuresis and sleep-interruptions in an elderly population of men and women in Denmark.Methods: The Nocturia, Nocturnal Enuresis and Sleep-interruption Questionnaire (NNES-Q) emerged from review of the literature and expert consensus. The questionnaire was a subset of a larger questionnaire comprising several domains on health status and voiding. Convergent and discriminatory validity was assessed in an unselected population of 2000 men and 2000 women 60-80 years old. To test reproducibility, 400 respondents were mailed a separate questionnaire 2 weeks apart. A subgroup of men and women with and without nocturia was used for evaluating reliability of number of nocturia episodes.Results: A total of 2825 (70.6%) filled in the questionnaire. A decrease in health status was correlated with increasing bother (range: -0.25 to -0.36, p < 0.001, Spearman's r). These findings indicate acceptable convergent validity. Significant discriminatory validity was proven in separate groups of symptom severity (p < 0.0001, Kruskal-Wallis test)Median kappa was 0.70 (range 0.58-0.86) indicating substantial agreement in the retest analysis. Number of nocturia episodes in questionnaires correlated with frequency volume charts (Spearman's rho 0.88; P < 0.001).Conclusion: These data support that the NNES-Q has a good discriminatory and convergent validity, and is reliable over time. The NNES-Q may be useful in epidemiological studies and may also have a potential in daily clinical work up in patients with nocturia and nocturnal enuresis. (c) 2006 Elsevier B.V.
