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 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. There was no significant difference in accuracy of reporting records to an interviewer versus a recording devvice, 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.
