Normative data for two MMPI critical item sets.
Addressed normative aspects of recent MMPI critical item sets proposed by Koss and Butcher (1973) and Lachar and Wrobel (1979). Base rates from MMPI Form R for these items were determined in samples of 123 normals, 383 inpatient alcoholics, and 567 psychiatric inpatients. Although pathological groups, as expected, generally endorsed more critical items than normals, mean differences were not large. On several critical item subsets, especially in the Koss -Butcher group, normals actually scored higher than the pathological samples. Caution is suggested when critical MMPI items are used in assessments.
