The Cornell Medical Index-Health Questionnaire (CMI) has been applied to psychosomatic medicine and preventive medicine such as the screening test of a general disease. The structure of the CMI and personality test questionnaires were examined by factor analysis. These questionnaires were self-administered by 155 female students ranging in age from 18 to 22. A total of thirty-seven items, including the 18 sections, A to R of the CMI, total “yes” responses of the CMI (TYR), 12 scales of the Yatabe-Guilford Test (Y-G Test), and 6 items of the Personality Inventory of Tokyo Institute of Technology (Personality Inventory), were analyzed by multiple correlation methods and the centroid methods.Correlation coefficients calculated between two items in the same questionnaire method gave very high values. Correlation coefficients, with especially high values between two items using different questionnaire methods, were those of the N-R sections in the CMI, TYR, D, C, I and N scales in Y-G Test, schizothymia, hysterical tendencies, and nervousness in the Personality Inventory.The multiple correlation coefficient between the TYR and personality was scored at 0.706, using Fukamachis discrimination group III scored 0.983.Seven factors were extracted by the centroid method. The first two factors were common for 37 items and had a pronounced contribution ratio amounting to 65.9%. The first factor was related to emotional stability, and the second factor was related to outside activity. These two factors of the TYR were accounted for 98.6% of cumulated contribution ratio. Therfore, it is believed that the TYR gives indexes of emotional stability and outside activity.
