E.船长自我和替代报告的饮食信息的比较。美国流行病学杂志1984; 119：86- 98。饮食在快速致死疾病病因学中的作用的研究可以利用从替代来源获得的数据。为了评估这些来源，46对受试者-配偶进行了访谈，并进行了旨在提供维生素A消耗指数的食物频率问卷调查。还获得了有关用量和既往使用模式的信息。频率和数量的信息被用来计算两个综合指数的维生素A的消费：一个基于频率单独和其他的基础上的频率和数量。对于单一食物，受试者及其配偶报告的平均消费频率是相似的;对于两种性别的组合，准确协议的平均水平为66%，在一个类别内的协议提高到93%。对于男性的每日维生素A摄入量，基于受试者数据的平均值与根据妻子的回答计算的平均值没有显着差异。对于妇女，丈夫少报了他们的总摄入量。受试者和代理人之间的协议为基础的整体维生素A的消费是不太令人满意的比个别食物。
Humble, C. G., J. M. Samet (New Mexico Tumor Registry, U. of New Mexico, Albuquerque, NM 87131) and B. E. Skipper. Comparison of self- and surrogate-reported dietary Information.Am J Epidemiol1984; 119: 86–98.Studies of dlet's role in the etiology of rapidly fatal diseases may utilize data taken from surrogate sources. To assess such sources, 46 subject-spouse pairs were Interviewed with a food frequency questionnaire designed to provide an Index of vitamin A consumption. Information concerning amount and past pattern of use was also obtained. The frequency and amount information was used to calculate two aggregate indices of vitamin A consumption: one based on frequency alone and the other based on frequency and amount. For single foods, the mean frequencies of consumption reported by subjects and by their spouses for them were similar; for both sexes combined, the average level of exact agreement was 66 per cent, with Improvement to 93 per cent for agreement within one category. Similar agreement was found for amount For the overall daily vitamin A intake of men, the means based on subject data were not significantly different from those calculated from their wives' responses. For women, husbands underreported their total intake. Agreement between subject- and surrogate-based overall vitamin A consumption was less satisfactory than for the individual foods.
