ABSTRACT
This study examines characteristics of Arbisi and Ben-Porath's (1995) MMPI-2 Infrequency-Psychopathology scale, F(p), in a sample of individuals admitted for inpatient treatment of chemical dependency. The F(p) scale, designed to detect deviant response biases in settings characterized by high base rates of psychopathology, was found by Arbisi and Ben-Porath (1995) to have good construct and incremental validity with psychiatric inpatients. Comparisons of the F(p), Infrequency (F), and Infrequency-Back (Fb) scales' means and relationships to indices of psychopathology in the current study provide evidence supporting the F(p) scale's validity in populations of chemically dependent inpatients with and without concurrent psychiatric diagnoses.

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.

The extent of codetype agreement between the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2) and estimated MMPI profiles was examined in a sample of 121 inpatients being treated for chemical dependence, primarily alcoholism. Rates of codetype agreement among the entire sample and various subsamples are comparable to those reported elsewhere derived for different samples and using different methods. Implications for MMPI-2 codetype interpretation are discussed.
