Abstract
Factor analysis of items from the psychiatric portion of the Cornell Medical Index (CMI) was performed to determine the empirical symptom dimensions in a sample of 1682 normal adult males. Factors were extracted and interpreted as irritability, inability to cope, depression, timidity, normal anxiety and clinical anxiety. The factors showed some correspondence to the clinical groupings in the CMI and to factors discovered in other studies. All showed small positive correlations with a measure of neuroticism, but these results argue against the hypothesis that the CMI M-R sections measure only a unitary factor of neurotic complaining. Modifications in the CMI are recommended to enhance its utility as a diagnostic or personality instrument.
