Personality Differences in Patients With Depressive Illness and Anxiety Neurosis

This study explores personality in subgroups of affective illness. Self‐assessment scores on Cattell's 16 Personality Factor (16 PF) Questionnaire were obtained from 87 patients comprising five groups, namely ill and recovered unipolar and bipolar depressives and chronic anxiety (CA) neurotics. It was predicted that the anxiety group would have more abnormal scores than both actively depressed groups, but the three groups had markedly similar traits. The prediction that three different types of personality profiles would be obtained from the two recovered depressive groups and the anxiety group was partly confirmed. However, the scores of the anxious patients were more similar to those of recovered unipolar depressives than either was to recovered bipolar depressives. It is suggested that the similar personalities of unipolar depressives and anxiety neurotics may be aetiologically important. Furthermore, the differences between the two recovered depressive groups supports the idea of distinguishing between sub‐populations in studies of affective illness.
