Effects of lateralized brain damage on factor scales of the MMPI

The present study examined the effects of lateralized brain damage on factoral scales of the Minnesota Multiphasic Personality Inventory (MMPI). Twenty subjects (ten with left hemisphere brain damage, ten with right hemisphere brain damage) closely matched on age, education, race and sex variables were administered the MMPI. t-tests on four factorial scales of the MMPI were computed between groups. None of the factor scale comparisons were statistically significant. Theoretical implications are discussed.
