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 Percep tion Difference (CCPD) score and a Special Score Difference (SSD) scor e were used for this purpose. CCPD and SSD scores were calculated by s ubtracting component X+% scores and weighted Special Score ratios foun d on the overall Rorschach from those unique to Cards VIII-X. CCPD sco res were found to be highly effective in differentiating a previously diagnosed borderline from a schizophrenic group. CCPD and SSD scores w ere correlated with MMPI scales for profile characteristics. (C) 1996 John Wiley & Sons, Inc.
