Short food questions (SFQ) allow for rapid reporting of food intake across a variety of settings but are limited by poor validity and reliability. Understanding the recall process used by parents to report children's food intake can improve question design and psychometric performance. This study aimed to improve understanding of how parents report children's dietary intake using SFQ. Semi-structured, cognitive interviews were conducted with 21 mothers of 3-7-year-old children. Mothers were asked to 'think-aloud' while answering SFQ about their child's food intake. Thematic analysis identified themes relating to parent's question and answer process and barriers to recall. Information retrieval strategies focused on 'use-of-time' and 'sphere of food provision' and differed for core versus unhealthy foods. Recall of routine and home food provision were used to report core food intake, whereas recall of special occasions and food provision outside the home guided recall of discretionary foods. Mothers utilize different recall strategies for core and discretionary foods based on use of time and the sphere of food provision. The ease of reporting children's dietary intake may be improved by utilizing a shorter recall time frame, clear and direct question wording, and use of food examples and recall prompts.
简短食物问卷 (SFQ) 可在各种环境下快速报告食物摄入量，但有效性和可靠性较差。了解父母用于报告儿童食物摄入量的回忆过程可以改进问题设计和心理测量性能。本研究旨在更深入地了解父母使用 SFQ 报告儿童饮食摄入的情况。对 21 名 3-7 岁儿童的母亲进行了半结构化认知访谈。要求母亲在回答有关孩子食物摄入量的 SFQ 时“边想边答”。主题分析确定了与父母问题和答案过程以及回忆障碍相关的主题。信息检索策略侧重于“用时”和“食物供应范围”，并因核心食物与不健康食物而异。常规和家庭食物供应的回忆用于报告核心食物摄入，而特殊场合和家庭以外食物供应的回忆则用于指导随意食物的回忆。母亲根据时间利用和食物供应范围，针对核心食物和随意食物采用不同的回忆策略。通过利用更短的回忆时间框架、清晰直接的问题措辞以及使用食物示例和回忆提示，可以提高报告儿童饮食摄入的便利性。
