| Abstract: | In the last two months have you had a physical examination?The ability of 660 people to accurately report on their ownrecent health procedures was assessed by comparing the recollectionsof patients to information extracted from their medical records.A major finding was that when people were asked whether theyhad a specific procedure in a given reference period (e.g.,physical exam within the last two months), overreporting occurred.A simple technique reduced overreporting: The technique entailedasking people about the procedure twice, first in connectionwith a different reference period (e.g., physical exam withinthe last six months) and then in connection with the referenceperiod of interest (e.g., physical exam within the last twomonths). Our data support a "Precision" hypothesis: The advantageof the two–time frame questioning procedure is that itconveys to the respondent that the interviewer wants greaterprecision in dating than the single–time frame questionimplies. |
