1 A large body of research on the demography of caffeine use and its potential health consequences has been undetermined by the absence of empirical data on the reliability of retrospective self-reports of caffeine consumption. 2 The principal aim of the present study was to use standard bioanalytic methods to assess the reliability of subjects'' self-reported caffeine use. Saliva samples were obtained from 142 first- and second-year medical students and assayed for caffeine and paraxanthine. 3 Self-reported caffeine use was found to be significantly correlated with salivary caffeine (r = 0.31, P < 0.001) and paraxanthine (r = 0.42, P < 0.001), thereby providing qualified support for the use of questionnaires to estimate patterns of caffeine consumption. 4 A secondary aim of the study was to extend previous research concerning the symptomatology of caffeine use by examining the association between caffeine exposure and a variety of measures of somatic and psychological health. Caffeine consumption was reliably associated with the self-reported occurrence of somatic symptoms, but not psychological well-being.
