![]() There is an infrequently used abbreviated form of the test that consists of the MMPI-2's first 370 items. The current MMPI-2 has 567 items, all in true-or-false format, and usually takes between 1 and 2 hours to complete, depending on reading level. Subsequent revisions of certain test elements have been published, and a wide variety of subscales was also introduced over many years to help clinicians interpret the results of the original clinical scales, which had been found to contain a general factor that made interpretation of scores on the clinical scales difficult. It is appropriate for use with adults 18 and over. The first major revision of the MMPI was the MMPI-2, which was standardized on a new national sample of adults in the United States and released in 1989. However, because the MMPI scales were created based on a group with known psychopathologies, the scales themselves are not atheoretical by way of using the participants' clinical diagnoses to determine the scales' contents. The atheoretical approach to MMPI development ostensibly enabled the test to capture aspects of human psychopathology that were recognizable and meaningful despite changes in clinical theories. The difference between this approach and other test development strategies used around that time was that it was atheoretical (not based on any particular theory), so the initial test was not aligned with the prevailing psychodynamic theories of that time. The original MMPI was developed in 1939 (Groth Marnat, Handbook of Psychological Assessment, 2009) using an empirical keying approach, which means that the clinical scales were derived by selecting items that were endorsed by patients known to have been diagnosed with certain pathologies. George, MA-MFT, says, "It's important to examine cultural bias, family of origin beliefs and histories, and other unique experiences because what might be considered 'normal' to one person could be out of the norm to someone else, culminating in a completely different emotional or behavioral response based simply on a world view lens." Significant changes in the MMPI-3, which have been motivated by ongoing research and clinical feedback, include new content, revised existing items, and a focus on addressing cultural bias to ensure the test’s applicability across diverse populations. The MMPI-3 test, which was published in 2020, builds upon these advancements by incorporating new items, updating norms, and refining scales to ensure the test’s continued relevance and accuracy. Subsequently, the MMPI-2-RF, which was published in 2008, streamlined the test, reducing the number of questions by over 200. The MMPI-2, which was introduced in 1989, addressed certain limitations of the original MMPI and incorporated updated norms and clinical scales. The evolution from the original MMPI test to the MMPI-3 represents a series of refinements and updates to enhance the test’s reliability and validity. Assessors then use these patterns, along with diagnostic criteria, to make informed diagnoses. ![]() The MMPI test is able to identify specific patterns of responses that can indicate various mental health conditions. The MMPI test can help diagnose conditions such as: It involves a comprehensive set of self-report questions that allow clinicians to evaluate various dimensions related to mental health. The MMPI test plays a critical role in diagnosing mental health conditions by providing psychologists with valuable insights into a person’s psychological functioning. MMPI Test’s Role in Diagnosing Psychological Conditions However, the MMPI is only one tool that mental health providers use when making a diagnosis. Where, for example, cognitive behavioral therapy would help change behaviors that may come with clinical depression, dialectical behavioral therapy might be a better choice for someone with borderline personality disorder." Meanwhile, in legal settings, it may be used in forensic evaluations, and in occupational settings, the MMPI is utilized for employee selection and placement. George, MA-MFT, explains that "having a full picture of a client's psychopathology at the time of diagnosis can help choose which therapeutic modality to use to best treat the client. In clinical settings, the MMPI is used to aid in diagnosing psychological disorders and creating treatment plans. Clinicians typically use it to gain insights into a person’s mental health, personality type, and potential mental health disorders. ![]() It consists of self-report questions designed to evaluate psychopathology, with an overall picture of a person's mental illness and personality. The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used psychological assessment tool.
