A taxometric analysis of MMPI-2 infrequency scales [F and F(p)] in clinical settings

The typology of overreporting, which is a deliberate attempt to amplify sym ptoms, simulate psychopathology, or understate coping capacities, was exami ned using taxometric procedures with Minnesota Multiphasic Personality Inve ntory-2 (MMPI-2) Infrequency scales [F and F(p)] in psychiatric inpatient a nd Veterans Affairs (VA) medical center treatment settings. Overreporting w as identified as a taxon using several taxometric procedures, and the multi ple estimates of the taxon base rate were consistent within each sample. Me an base-rate estimates were. 27 and .19 for the psychiatric inpatient and V A medical center settings, respectively. Overall classification rates range d from .80 to .97 across the 2 settings, which supports the use of F and F( (p) in the identification of overreporting on the MMPI-2 in psychiatric inp atient and VA medical center settings.
