A study was made to compare accuracy of the 24-hour recall, including both number of items recalled and amounts of food eaten, for elderly subjects using three methods: I, unaided oral recall, II, printed questionnaire, and III, interview with actual-size color pictures of foods. Sixty hospitalized patients, age 65 to 94, were interviewed. Factors studied for influence on scores were age, sex, educational level, obesity, place of residence, and food preparer. Results showed no significant difference in scores owing to method used, except that 30 subjects above the median age of 76 scored higher on number of items recalled and amounts of food eaten when using the printed questionnaire. None of the demographic factors studied made a significant difference in scores.
一项研究旨在比较三种方法用于老年受试者时24小时回忆的准确性，包括回忆的食物种类数量和进食量：方法一，无辅助口头回忆；方法二，纸质问卷；方法三，使用食物实际大小彩色图片进行访谈。研究对60名年龄在65至94岁的住院患者进行了访谈。研究探讨了年龄、性别、教育程度、肥胖、居住地点和食物制备者等因素对得分的影响。结果显示，因使用方法不同，得分无显著差异，但76岁中位数年龄以上的30名受试者在使用纸质问卷时，回忆的食物种类数量和进食量得分更高。所研究的人口统计学因素在得分上均无显著差异。
