Step-by-step explanation:
The personality test most concerned with assessing abnormalities in personality is the Minnesota Multiphasic Personality Inventory (MMPI-2). The MMPI-2 is a self-report inventory that consists of a series of true/false questions designed to establish a clinical profile of an individual. It is used not only for diagnosing psychological problems but also for occupational screening and counseling. The MMPI-2 is comprehensive and includes scales for various psychological conditions such as depression, schizophrenia, and paranoia. It is distinct from the other personality assessments mentioned, such as the Myers-Briggs Type Indicator (MBTI), which is more focused on assessing personality types rather than detecting psychopathology.
