Within-scale item content is heterogeneous and some scales tap multiple constructs, complicating the interpretation of scale elevations and limiting construct validity ( Tellegen et al., 2003). Despite clear strengths, there are psychometric limitations to its main scales, the Clinical Scales (CSs). Its extensive array of scales, established norms for a range of populations, and unparalleled breadth of research provides a solid foundation from which to evaluate the profiles of individuals with PTSD for clinical description, case conceptualization, and treatment planning purposes. The Minnesota Multiphasic Personality Inventory-2 (MMPI-2 Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) is one of the most widely used assessment instruments in mental health and, as such, is often used in the assessment of posttraumatic stress disorder (PTSD). The PK scale demonstrated incremental validity in the prediction of PTSD beyond that of the RCSs or CSs. A notable advantage of the RCSs compared to the MMPI-2 CSs was their enhanced construct validity and clinical utility in the assessment of comorbid internalizing and externalizing psychopathology. The RCSs demonstrated good psychometric properties along with patterns of associations with other measures of psychopathology that corresponded to current theory regarding the structure of comorbidity.
The utility of the RCSs was compared to that of the Clinical Scales (CSs) and the Keane PTSD (PK) scale. Study 2 included 136 women who completed the MMPI-2 and were interviewed with the Clinician Administered Scale for PTSD. Study 1 included 1,098 men who completed the MMPI-2 and were assessed for a range of psychological disorders via structured clinical interview. This study examined the psychometric properties of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Restructured Clinical Scales (RCSs) in individuals with posttraumatic stress disorder (PTSD) receiving clinical services at Veterans Affairs medical centers.
