A facet level analysis of the concurrent and construct validity of the MCMI-III Grossman Facet Scales using the MMPI-2-RF specific problems scales as the criterion

Both the Millon Clinical Multiaxial Inventory-III (MCMI-III) and the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) are well established assessment instruments that were developed to help clinicians better understand dimensions of personality and psychopathology. In recent years, each instrument has added subscales, which provide a more detailed understanding of the manifestations of the personality and psychopathology within the client. The granularity afforded by these subscales (Specific Problems Scales of the MMPI-2-RF and Grossman Facet Scales of the MCMI-III) have become increasingly appreciated by the test users. However, while the clinical use of these subscales has grown, there is very little data on the concurrent and construct validity of the Grossman Facet Scales. This study examined the concurrent and construct validity of the Grossman Facet Scales using the Specific Problems Scales as the criterion measure. Data used for these analyses were obtained from 440 adult psychiatric inpatients hospitalized in a facility located in a mid-sized city in the Midwestern United States (U.S.) who underwent both assessments during their inpatient stay. The concurrent validity was assessed through the examination of a zero order correlation matrix. The construct validity was assessed with principal axis factoring with a four factor solution, as this solution best displayed simple structure and psychological meaningfulness. Collectively, these results provide evidence for the Grossman Facet Scales' construct validity. Furthermore, correlational analysis indicated the Grossman Facet Scales and MMPI-2-RF Specific Problems Scales covary in theoretically meaningful ways.
