1985年，216名男性参与了巴尔的摩老龄化纵向研究，他们被要求报告1971-1975年期间的日常饮食。过去饮食的参考数据包括1971年至1975年期间收集的多个7天记录。该组被随机分配，以完成饮食史，无论是个人访谈或邮寄自我管理的问卷。两种情况下的项目和回答类别相同。对于两组，通过问卷调查估计的平均营养素摄入量在. ±.过去饮食中大多数营养素的记录值的10%。当调查问卷由一名访谈者进行管理时，与过去饮食的相关性与其他研究中目前饮食的相关性大致相同，表明可以使用此问卷对过去饮食进行有用的研究。邮件组的相关性相当低，表明使用这种问卷格式评估过去的饮食，而不需要个人指导或回调可能会产生很差的结果。年龄的影响是可以忽略不计的，但响应错误和饮食的变化，因为目标期间有重要的影响与过去的饮食在采访和邮件组的相关性。
In 1985, 216 men, participants in the Baltimore Longitudinal Study of Aging were asked to report on their usual diet during the period 1971-1975. The reference data for past diet consisted of multiple seven-day records collected between 1971 and 1975. The group was randomly assigned to complete the diet history either by personal interview or by mailed self-administered questionnaire. The items and response categories were identical in both cases. For both groups, the mean nutrient intake estimate by questionnaire was within .+-. 10 per cent of the past diet record values for most nutrients. When the questionnaire was administered by an interviewer, correlations with past diet were approximately as good as those obtainable with present diet in other studies and indicate that useful studies of past diet can be performed with this questionnaire. Correlations for the mail group were considerably lower and suggest that assessment of past diet using this questionnaire format without personal instruction or callbacks may yield poor results. The effect of age was negligible, but response errors and change in diet since the target period had important effects on correlations with past diet in both interview and mail groups.
