This paper uses five strategies to evaluate the reliability and other measurement qualities of the Ten Questions screen for childhood disability. The screen was administered for 22,125 children, aged 2-9 years, in Bangladesh, Jamaica and Pakistan. The test-retest approach involving small sub-samples was useful for assessing reliability of overall screening results, but not of individual items with low prevalence. Alternative strategies focus on the internal consistency and structure of the screen as well as item analyses. They provide evidence of similar and comparable qualities of measurement in the three culturally divergent populations, indicating that the screen is likely to produce comparable data across cultures. One of the questions, however, correlates with the other questions differently in Jamaica, where it appears to "over-identify" children as seriously disabled. The methods and findings reported here have general applications for the design and evaluation of questionnaires for epidemiologic research, particularly when the goal is to gather comparable data in geographically and culturally diverse settings.
本文采用五种策略来评估儿童残疾十项问题筛查表的可靠性及其他测量质量。该筛查表在孟加拉国、牙买加和巴基斯坦对22125名2至9岁儿童进行了施测。涉及小样本的重测方法有助于评估总体筛查结果的可靠性，但对于患病率较低的个别项目则不适用。替代策略侧重于筛查表的内部一致性和结构以及项目分析。它们提供了证据，表明在这三个文化差异较大的人群中测量质量相似且具有可比性，这表明该筛查表在不同文化中可能会产生可比的数据。然而，其中一个问题在牙买加与其他问题的相关性有所不同，在那里它似乎会“过度认定”儿童为严重残疾。本文所报告的方法和结果对流行病学研究问卷的设计和评估具有普遍应用价值，特别是当目标是在地理和文化多样的环境中收集可比数据时。
