The WAIS and Rorschach test in diagnosing borderline personality.

This study assesses the degree to which indicators from the Rorschach and the WAIS discriminate between the two groups of psychiatric inpatients diagnosed as having either borderline or psychotic personality organization by means of Kernberg's structural interview. A combination of WAIS scores focusing on the Picture Completion subtest, and Rorschach form level proved to be discriminators. These were interpreted as primarily reflecting reality testing. A linear combination of WAIS scale scores was identified that discriminated at least as well as the clinical WAIS-Rorschach comparisons.
