Abstract

This study determined the accuracy of self-reports of prostate-specific antigen (PSA) testing. Men (N = 402) attending 2 outpatient clinics were asked: "Did you have a PSA test today?" and their medical records were checked. Concordance, sensitivity, and false-negative values were 65%, 67%, and 33%, respectively, at 1 clinic site and 88%, 64%, and 36% at the other. The accuracy of self-reports of PSA testing should be interpreted with caution.
