Utility of the MMPI-168 with men inpatient alcoholics

The ability of the MMPI-168 to estimate full-scale high-point code types was evaluated in 772 men inpatient alcoholics. Although concordance of code types was found to be 35% across the entire sample, concordance rates of specific codes varied from 78% for the 2-4/4-2 type to only 15% for the 7-8/8-7 type. The MMPI-168 also underestimated the frequency of many full-scale code types. Overall, the data indicated that the MMPI-168 should be used very cautiously with alcoholics when the goal is to estimate full-scale code types.
