Rorschach indicators of Multiple Personality Disorder.
The increase in reported cases of Multiple Personality Disorder underscores a great need to differentiate clearly this from other psychiatric disorders and from simulation of Multiple Personality Disorder. Two sets of Rorschach signs have been advanced as clinical markers by their developers, namely Barach and also Wagner, Allison, and Wagner. As the Wagner signs are prevalent in much of the research on Rorschach responses in Multiple Personality Disorder, the purpose of the present study was to evaluate these signs using Wagner's administration and the resulting Rorschach protocols of 16 Multiple Personality Disorder patients and 16 psychiatric controls. Analysis indicated that this system was deficient in correctly classifying these 32 protocols. A new marker, the Splitting Response, emerged, however, which was more useful. This response, in combination with at least one Dissociative response, produced an accuracy rate of 94%. These new criteria may be useful aids in the detection of Multiple Personality Disorder from Rorschach protocols. Replication is urged.
