Abstract

The incremental contribution of the MMPI-2 Content Scales to the prediction of scores on self-report measures of personality and psychopathology was investigated. The MMPI-2, Beck Depression Inventory, State-Trait Personality Inventory, and Symptom Checklist—90-Revised were administered to 596 subjects: 339 women and 257 men. Zero-order correlational analyses indicated that both clinical and Content Scales correlated with each of the criterion measures. In all but one case, an MMPI—2 Content Scale was found to have the highest correlation with the extratest variables. Combined hierarchical, stepwise regression analyses demonstrated that the MMPI-2 Content Scales possess incremental validity vis-à -vis the clinical scales for both genders in relation to all of the criterion measures. Additional analyses indicated that the MMPI-2 clinical scales also possess incremental validity vis-à -vis the Content Scales. However, the incremental contribution of the clinical scales was of lesser magnitude. Implications of these findings for test interpretation and future research with the MMPI-2 are discussed.
