认知访谈方法被用来适应问题从美国食品安全调查模块管理的儿童。使用标准化探针的个体并行探测技术用于评估20名非裔美国儿童（10名男性，10名女性，年龄11-13岁）对项目的理解。修订了项目措辞和回答集，并要求12-15岁的男孩（n = 5）和女孩（n = 14）完成9项调查。然后使用回顾性探测技术来评估项目和响应集的理解。九个项目，然后试点在一所中学使用自我管理的格式。共收到345份调查问卷。大多数学生年龄在12至15岁之间（n = 215）。使用基于Rasch计量模式的统计方法对345项已完成的调查进行的比例分析表明，该模块计量的是一个单一的基本现象（粮食不安全），具有足够的可靠性，是一个有用的工具。粮食不安全的可测量范围约为估计测量误差的6倍，表明该量表能够以合理的可靠性识别3类粮食安全。一个可靠地衡量个别儿童的粮食安全状况的调查工具可以为研究人员提供一个重要的工具，以更准确地评估粮食安全对这一人群的营养状况和身心健康的个人层面的影响。
Cognitive interviewing methods were used to adapt questions from the U.S. Food Security Survey Module for administration to children. Individual concurrent probing techniques using standardized probes were utilized to assess understanding of the items with 20 African American children (10 males, 10 females, aged 11-13 y). Item wording and response sets were revised, and small groups of boys (n = 5) and girls (n = 14) aged 12-15 y were asked to complete the 9-item survey. Retrospective probing techniques were then used to assess comprehension of items and response sets. Nine items were then piloted in a middle school using a self-administered format. Three hundred forty-five surveys were returned. The majority of the students were between 12 and 15 y (n = 215). Scaling analysis of the 345 completed surveys using statistical methods based on the Rasch measurement model indicated that the module measured a single underlying phenomenon (food insecurity) with sufficient reliability to be a useful tool. The measurable range of food insecurity was about 6 times the estimated measurement error, indicating that the scale could identify 3 categories of food security with reasonable reliability. A survey instrument that reliably measures food security status of individual children can provide researchers with an important tool to assess more accurately the individual-level effects of food security on nutritional status and mental and physical health among this population.
