Abstract

This article examined the incremental validity of the Ego Impairment Index(Ell), a Rorschach measure of cognition. perception. and reasoning. R. M. Dawes (1999) borrowed 2 previously published data sets to assess the incremental validity of the Ell. Dawes determined that in order for the Ell to beconsidered a valid measure. the overall Ell score should "outperform" 2 ofthe variables that compose the index. Using this approach. Dawes reported that the Ell had "deficient" (p = .059) incremental validity. In this study, the incremental validity of the Ell was re-examined using I of the data sets used by R. M. Dawes (1999). Applying the same strategy as Dawes, the author tested the incremental validity of the Ell in predicting positive symptoms of schizophrenia, a more appropriate and clinically relevant criterionmeasure of impairment. The Ell significantly predicted positive symptoms (p < .005) even after the 2 Ell variables selected by Dawes and the measure of social competence were I st entered into the equation. The results suggest that the EII adds meaningful information in the assessment of thought disturbance.
