目的：探讨儿童对学校早餐和学校午餐的饮食回忆的准确性。设计：观察每个儿童吃学校早餐和学校午餐的情况，并在当晚就当天的饮食回忆进行访谈。地点：10所小学。参与者：在种族(黑人、白人)和性别阶层中随机选择一名四年级学生，观察，测量的主要结果：计算遗漏(观察到但未报告的项目)和侵入(报告但未观察到的项目)的比率，以确定报告项目的准确性。结果：面谈类型(面对面、电话)对回忆的准确性没有显著影响。在遗漏率、侵入率和总不准确率方面，面对面回忆的平均值分别为34%、19%和4.6份，电话回忆的学校早餐和学校午餐的平均含量分别为32%、16%和4.3份。结论与启示：儿童对学校早餐和学校午餐的回忆准确率无论是亲自回忆还是电话回忆都没有显著差异。无论是当面采访还是电话采访，孩子们都只报告。67%的物品被观察到；此外，17%的报告物品没有被观察到。
Objective: To investigate the accuracy of children's dietary recalls of school breakfast and school lunch validated with observations and obtained during in-person versus telephone interviews.Design: Each child was observed eating school breakfast and school lunch and was interviewed that evening about that day's intake.Setting: Ten elementary schools.Participants: A sample of fourth-graders was randomly selected within race (black, white) and gender strata, observed, and interviewed in person (n = 33) or by telephone (n = 36).Main Outcomes Measured: Rates for omissions (items observed but not reported) and intrusions (items reported but not observed) were calculated to determine accuracy for reporting items. A measure of total inaccuracy was calculated to determine inaccuracy for reporting items and amounts combined.Analysis: Analysis of variance; chi-square.Results: Interview type (in person, telephone) did not significantly affect recall accuracy. For omission rate, intrusion rate, and total inaccuracy, means were 34%, 19%, and 4.6 servings for in-person recalls and 32%, 16%, and 4.3 servings for telephone recalls of school breakfast and school lunch.Conclusions and Implications: The accuracy of children's recalls of school breakfast and school lunch is not significantly different whether obtained in person or by telephone. Whether interviewed in person or by telephone, children reported only. 67% of items observed; furthermore, 17% of items reported were not observed.
