Synopsis

In a study of pre-morbid personality in 56 head-injured subjects, subjects' self-ratings of pre-morbid personality were compared with informants' ratings of the subjects' pre-morbid personality on two personality questionnaires (the Eysenck Personality Inventory (EPI) and the Marke-Nyman Temperament Scale (MNTS)). Correlations between self-ratings and informantratings were positive and significant for all three MNTS and for EPI Extraversion and Lie scales, but not for EPI Neuroticism, where the lack of subject-informant correlation was attributed to contamination of the self-rating of the trait measure by current abnormalities of mental state. Further analyses supported previous evidence that the MNTS ‘Validity’ scale may predict the development of psychiatric symptoms.
