This study focused on the clinical field validity of the Rorschach comprehensive system revised DEPI and CDI indices. Forty admission protocols from two inpatient adult DSM-III-R diagnosed samples, one with Major Depressive Disorder, uncomplicated, and one with Major Depressive Disorder and concurrent Borderline Personality Disorder, were compared. Hypotheses were (a) both groups would be identified by the revised DEPI and (b) if the Depressed Borderline group was not identified by the DEPI, it would be identified by the CDI. Both hypotheses were negated, raising questions regarding the validity of the indices for use in clinical diagnosis, treatment, and clinical research.
