Minnesota Multiphasic Personality Inventory
Also written as: MMPI — Minnesota Multiphasic Personality Inventory
A standardized psychometric test used to assess personality traits and psychopathology in adolescents and adults.
Full Definition
The Minnesota Multiphasic Personality Inventory (MMPI) is one of the most widely used psychological assessment instruments for evaluating personality characteristics and identifying mental health disorders. The current version, MMPI-2-RF, contains 338 items that generate scores on validity scales, clinical scales, and numerous supplementary scales. Originally developed in the 1940s, the MMPI has undergone several revisions to improve its psychometric properties and cultural relevance. The test is particularly valuable for differential diagnosis, treatment planning, and forensic evaluations, though interpretation requires specialized training in psychological assessment.
Usage
Usage note: Always specify version (MMPI-2, MMPI-2-RF, MMPI-A) as scoring and interpretation differ significantly.
