Abstract
This study was designed to ascertain the validity and clinical utility of the Ego Impairment Index (EII) in two groups of major depressive disorder and schizophrenia diagnosed with the DSM-IV. Two groups of patients were tested by the Rorschach and the MMPI. The results were as follows: 1) The EII components were significantly interrelated and a single factor was derived from the factor analysis. 2) As hypothesized, the degree of ego impairment was greater in patient's with schizophrenia than those with major depressive disorder. 3) Barron's ego strength scale of the MMPI was not significantly correlated with the index. 4) As results of discriminant function analysis, the correct discriminating mean power of this discriminant function was 90%. Therefore, this results offer support for the use of the EII as an empirical means of assessing the degree of ego impairment.
