Six methods of assessing individual food intake reported by telephone were compared for accuracy. A sample of 107 students eating in a dormitory dining hall was used. Two 7-day and four 3-day diet records were reported by telephone to either an interviewer or an answering device; and fourteen 6-h recalls and seven 24-h recalls were obtained by an interviewer over the telephone. To examine validity, the investigators observed respondents' intake for 28 days. Food item agreement scores comparing observed and reported data were calculated. Seven-day records were most accurate (87% food item agreement); 3-day records and 6-h recalls were equivalent (75%); and 24-h recalls were least accurate (69%). There were no significant difference in accuracy of reporting records to an interviewer versus a recording device, but respondents preferred the interviewer. Results of telephoned reporting compare favorably with personal interview techniques used by other investigators, indicating that telephoned methods should be further explored in community settings.
对通过电话报告的六种评估个人食物摄入量的方法的准确性进行了比较。使用了107名在宿舍食堂就餐的学生作为样本。通过电话向访谈员或录音设备报告了两份7天和四份3天的饮食记录；访谈员通过电话获得了14份6小时回忆和7份24小时回忆。为了检验有效性，研究人员对受访者的摄入量进行了28天的观察。计算了比较观察数据和报告数据的食物项目一致性得分。7天记录最准确（食物项目一致性为87%）；3天记录和6小时回忆相当（75%）；24小时回忆最不准确（69%）。向访谈员报告记录与向录音设备报告记录的准确性没有显著差异，但受访者更喜欢访谈员。电话报告的结果与其他研究人员使用的个人访谈技术相比具有优势，表明在社区环境中应进一步探索电话方法。
