MMPI-2 critical item norms in chemically dependent inpatients

The present study investigates the frequency of critical item endorsement for two MMPI-2 critical item sets in a population of inpatients being treated for chemical dependency. Base rates of endorsement in the current study are compared to the results of previous studies using the original MMPI, and relationships between item endorsement and various demographic and diagnostic variables are explored. Implications regarding the utility of critical items in chemically dependent populations are discussed.
