Which test is commonly used in clinical psychology for diagnosing mental disorders?

The Minnesota Multiphasic Personality Inventory (MMPI-2) is widely regarded as one of the most reliable and valid tools for diagnosing mental disorders within clinical psychology. It is a standardized psychometric test designed to assess various psychological conditions and personality attributes. The strength of the MMPI-2 lies in its empirical foundation, having been developed based on extensive research that links specific psychological patterns to potential mental health issues.

The test includes a comprehensive set of scales that evaluate a range of psychological conditions, including but not limited to anxiety, depression, paranoia, and personality disorders. Clinicians often use the MMPI-2 to support a diagnosis by comparing an individual's scores against normative data, which helps in understanding how their psychological state compares to a broader population.

In contrast, other options serve different purposes: the NEO-PI Test focuses primarily on personality traits rather than clinical diagnosis; the Myers-Briggs Type Indicator evaluates personality types for understanding personal preferences and motivations and is not meant for diagnosing mental disorders; and while the Rorschach Inkblot Test can offer insights into an individual’s personality and emotional functioning, it lacks the diagnostic validity and empirical backing of structured tests like the MMPI-2.
