目的 描述为青年冠状动脉危险因素发展 (CARDIA) 研究开发的饮食史调查问卷的计算机化方法，并描述与饮食评估结合使用的质量控制程序。 设计 计算机化饮食史正在病例对照研究中使用。由于问卷的计算机化性质，我们制定了质量控制程序，其中包括听访谈录音带并目视审查记录的数据。设置三个中心参与基于人群的结肠癌流行病学研究。受试者年龄在 30 至 79 岁之间的男性和女性。结果质量控制结果表明，如果仅对数据进行目视审查，则 100% 的计算机化表格不会出现错误。探测错误占所有错误的 47.3%，是最常见的错误。在探究错误时，访调员没有以非指导性的方式进行探究，或者访调员未能验证可能被认为有问题的回答。 应用 CARDIA 饮食历史经过计算机化，用于饮食与疾病之间关联的流行病学研究。对访谈录音带的审查表明，通过对数据的目视审查无法发现在获得饮食评估时所犯的大多数错误。尽管质量控制程序是为计算机化饮食史问卷开发的，但它们也适用于其他饮食评估方法。
Objective To describe methods used to computerize the diet history questionnaire developed for the Coronary Artery Risk Factor Development in Young Adult (CARDIA) study and to describe quality-control procedures used in conjunction with dietary assessment.Design The computerized diet history is being used in a case-control study. Because of the computerized nature of the questionnaire, we developed quality-control procedures that incorporate listening to an audiotape of the interview while visually reviewing recorded data.Setting Three centers involved in a population-based epidemiologic study of colon cancer.Subjects Men and women between the ages of 30 and 79 years.Results Quality-control results showed that 100% of the computerized forms would be free of errors if the data were subjected to visual review only. Probing errors, which accounted for 47.3% of all errors, were the most commonly encountered errors. In probing errors the interviewer did not probe in a nondirective manner, or the interviewer failed to verify responses that might be considered questionable.Applications The CARDIA diet history was computerized for use in epidemiologic studies of the association between diet and disease. Review of the audiotapes of the interviews showed that most errors made in obtaining a dietary assessment were not detectable from visual review of the data. Although the quality-control procedures were developed for a computerized diet history questionnaire, they are applicable to other dietary assessment methods.
