The Cornell Medical Index-Health Questionnaire

The Cornell Medical Index-Health Questionnaire is a self-administered instrument that collects a large body of significant medical and psychiatric data without the physician's participation, so that the physician may have available, even before he interviews the patient, information on which to base tentative diagnostic appraisals of the patient's total medical problem. This communication reports the accuracy and completeness of the diagnostic appraisals that can be made with the data on the Cornell Medical Index.
