This study examined the MMPI-derived personality profiles of three learning-disabled sub-types. Results obtained through profile analysis indicated that there were no significant differences between the three groups on the validity and 10 basic scales of the MMPI. However, the combined learning-disabled groups differed significantly from the normative sample on the MMPI, scoring higher on 11 of the 13 scales studied. Statistical analyses revealed that 20% of the LD sample displayed significantly marked elevations on one or more of the MMPI scales.
