MMPI mean profiles for matched groups of 50 brain-damaged and 50 schizophrenic Ss from a short-term hospital were compared. The profiles are quite different. F tests demonstrated that the Sc scale best differentiated the two groups at far beyond the .01 level, and scales F, PA and PT also differentiated the two groups beyond the .01 level. A cut-off point of 80 on the SC scale correctly classified 78% of the two groups. Neither the 2-9 nor the 1-3-9 profile occurred a sufficient number of times in either group to be of any help in diagnosis.
