Prediction of homicide with the Rorschach.

The use of a step-wise multiple discriminant analysis indicated that the Rorschach variables of S, A, P and m could discriminate with a good degree of accuracy the Rorschach protocols of murderers from those of nonmurderers. These empirically derived linear discriminant functions may serve as a useful adjunct to the clinical interpretation of Rorschach protocols in a criminal population.
