Using the same questionnaire, personnel, and field procedures, we conducted interviews in 1985 with the next-of-kin of 108 deceased study subjects, and with 197 surviving subjects who had been interviewed earlier in a 1980 case-control study. Concordance in response between the two interviews for cigarette smoking, coffee drinking, and alcoholic beverage intake was high, generally 90% or above. Next-of-kin, particularly spouses, provided information as reliable as the self-informants for cigarette smoking and coffee consumption, but showed a somewhat higher discrepancy rate for alcohol drinking. Thus, surrogates, especially spouses, appear to be an accurate source of information in epidemiologic investigations.
我们使用相同的调查问卷、工作人员和实地调查程序，于1985年对108名已故研究对象的近亲进行了访谈，并对197名在1980年病例对照研究中接受过早期访谈的存活对象进行了访谈。两次访谈在吸烟、喝咖啡和饮酒摄入量方面的回答一致性很高，通常在90%或以上。近亲，尤其是配偶，在吸烟和咖啡消费方面提供的信息与自我报告者一样可靠，但在饮酒方面的差异率略高。因此，替代者，尤其是配偶，似乎是流行病学调查中准确的信息来源。
