Background:Formal validation studies are of critical importance in determining whether or not household survey questions are providing accurate information on what they intend to measure. These studies supplement an array of methods used to evaluate survey questions. Methods and Findings:This paper summarizes the methods used by the two major international household survey programmes - The Demographic and Health Surveys Program (DHS) and the Multiple Indicator Cluster Surveys (MICS) - to decide on possible modifications to the survey questions, nomenclature, tables, and interpretation of findings over time as additional information on the validity of the questions becomes available. Conclusions:Validation studies are most useful if they are conducted in a variety of different settings in low- and middle-income countries, preferably using representative samples and procedures that replicate DHS and MICS field conditions. Pilot tests, pre-tests in each country, feedback from interviewers and survey staff, and cognitive interviewing provide additional information about how well survey questions are understood and provide accurate information. The paper provides specific examples of changes that have been made in response to findings from validation studies and changes in international recommendations.

背景:正式的验证研究对于确定家庭调查问题是否提供有关他们打算测量的准确信息至关重要。这些研究补充了用于评估调查问题的一系列方法。
方法和发现:本文总结了两个主要的国际家庭调查计划-人口与健康调查计划(DHS)和多指标类集调查(MICS)-用于决定对调查问题,术语,表格,以及随着时间的推移对发现的解释,因为可以获得有关问题有效性的更多信息。
结论:如果在低收入和中等收入国家的各种不同环境中进行验证研究,则最有用,最好使用具有代表性的样本和重复DHS和MICS现场条件的程序。试点测试,每个国家/地区的预测试,访调员和调查人员的反馈以及认知访谈提供了有关如何更好地理解调查问题并提供准确信息的其他信息。本文提供了一些具体示例,这些示例是针对验证研究的结果和国际建议的更改而做出的更改。
