The use of computers to administer dietary assessment questionnaires has shown potential, particularly due to the variety of interactive features that can attract and sustain children's attention. Cognitive interviews can help researchers to gain insights into how children understand and elaborate their response processes in this type of questionnaire.
To present the cognitive interview results of children who answered the WebCAAFE, a Web-based questionnaire, to obtain an in-depth understanding of children's response processes.
Cognitive interviews were conducted with children (using a pretested interview script). Analyses were carried out using thematic analysis within a grounded theory framework of inductive coding.
A total of 40 children participated in the study, and 4 themes were identified: (1) the meaning of words, (2) understanding instructions, (3) ways to resolve possible problems, and (4) suggestions for improving the questionnaire. Most children understood questions that assessed nutritional intake over the past 24 hours, although the structure of the questionnaire designed to facilitate recall of dietary intake was not always fully understood. Younger children (7 and 8 years old) had more difficulty relating the food images to mixed dishes and foods eaten with bread (eg, jam, cheese). Children were able to provide suggestions for improving future versions of the questionnaire.
More attention should be paid to children aged 8 years or below, as they had the greatest difficulty completing the WebCAAFE.
使用计算机管理饮食评估问卷已显示出潜力，特别是由于其具有多种能够吸引并维持儿童注意力的互动功能。认知访谈有助于研究人员深入了解儿童在这类问卷中如何理解和阐述其回答过程。
展示回答基于网络的问卷WebCAAFE的儿童的认知访谈结果，以深入了解儿童的回答过程。
对儿童进行认知访谈（使用预先测试的访谈脚本）。在归纳编码的扎根理论框架内使用主题分析进行分析。
共有40名儿童参与了该研究，确定了4个主题：（1）单词的含义，（2）理解说明，（3）解决可能问题的方法，以及（4）对改进问卷的建议。大多数儿童理解评估过去24小时营养摄入量的问题，尽管旨在促进饮食摄入量回忆的问卷结构并非总能被完全理解。年龄较小的儿童（7岁和8岁）在将食物图片与混合菜肴以及与面包一起食用的食物（如果酱、奶酪）联系起来时遇到更多困难。儿童能够为改进问卷的未来版本提供建议。
应更多关注8岁及以下的儿童，因为他们在完成WebCAAFE时遇到的困难最大。
