Which instrument is the Minnesota Multiphasic Personality Inventory?

• A. Milon Instruments
• B. MMPI
• C. MBTI
• D. CBCL

Answer: (B)

The Minnesota Multiphasic Personality Inventory is a widely used, standardized self-report tool clinicians rely on to assess mental health and personality structure. It presents a large set of statements that respondents answer true/false (with some versions allowing additional response formats), providing a comprehensive profile of symptoms and personality patterns. The MMPI includes validity scales to detect inconsistent or biased responding, which helps determine whether the results are trustworthy. Over time, it has evolved into versions like MMPI-2, MMPI-2-RF, and MMPI-A for adolescents, all aimed at aiding diagnosis, treatment planning, and research into personality and psychopathology.

Other options refer to different tools: MBTI (Myers-Briggs Type Indicator) focuses on personality type preferences rather than clinical psychopathology; the Child Behavior Checklist assesses behavioral and emotional problems in children; Milon Instruments isn’t a standard, widely recognized clinical measure. Hence, the instrument described by the Minnesota Multiphasic Personality Inventory is the MMPI.
