The Minnesota Multiphasic Personality Inventory 2 (MMPI-2) is generally regarded as a psychometrically sound personality assessment instrument that can be readily defended in the courtroom with respect to standardization, reliability, and validity, and potential clinical and forensic benefits of integrating MMPI-2 findings with other sources of information are discussed.
Abstract
Despite its demonstrably good psychometric qualities, the MMPI-2 has not yet been examined sufficiently with respect to demographic subgroup norms, long-term temporal stability, and predictive validity, and the instrument is vulnerable to cross- examination in these areas. The MMPI-2 can be used most effectively in clinical and forensic assessments when combined with other instruments to compare and contrast indications of problems, complaints, and characteristics, as manifested on both structured and unstructured assessment instruments. The role of psychologists who testify in forensic cases is examined in relation to the adequacy of the MMPI-2 as an assessment instrument. Further research on the psychometric foundation of the MMPI-2 is recommended, particularly with regard to the reliability and validity of normative data. 35 references
