Measuring the effect of the Rorschach color cards (VIII-X) on perceptual accuracy and special scores in differentiating borderline from schizophrenic protocols.

In this study, measures were developed that compared conventional Form accuracy and the ratio of Special Scores on Cards VIII-X (Color Cards) with overall Rorschach scores. Two new measures, a Color Card Perception Difference (CCPD) score and a Special Score Difference (SSD) score were used for this purpose. CCPD and SSD scores were calculated by subtracting component X + % scores and weighted Special Score ratios found on the overall Rorschach from those unique to Cards VIII-X. CCPD scores were found to be highly effective in differentiating a previously diagnosed borderline from a schizophrenic group. CCPD and SSD scores were correlated with MMPI scales for profile characteristics.
