| Abstract: | Many concerns have been raised about the MMPI, but the emphasis on continuity during its revision precluded addressing many of these problems in the new MMPI-2. In this review, problems with the MMPI and MMPI-2 are explicated in an effort to promote more informed use of this and other tests of psychopathology. Major theoretical concerns include the lack of a consistent measurement model, heterogeneous scale content, and suspect diagnostic criteria. Serious structural problems include the overlap among scales, lack of cross-validation of the scoring keys, inadequacy of measures of response styles, and suspect norms. Six minor problems and new issues for the MMPI-2 are also discussed. It is concluded that although the MMPI-2 is an improvement over the MMPI, both are suboptimal from the perspective of modern psychometric standards for the assessment of psychopathology.
