Final answer:
The RIASEC model is used to identify an individual's career interests based on six personality types. It differs from the Myers-Briggs Type Indicator (MBTI), which has 16 personality types and from the Minnesota Multiphasic Personality Inventory (MMPI) which uses true/false questions for psychological assessment.
Step-by-step explanation:
The personality model used to identify an individual's career interests based on six personality types is the RIASEC model. This model isn't to be confused with the Myers-Briggs Type Indicator (MBTI), which has four categories and generates 16 different personality types based on a spectrum from the hard extremes. The RIASEC model, also known as Holland Codes, delineates six personality types that are associated with career preferences. In contrast, the Minnesota Multiphasic Personality Inventory (MMPI) is a self-report inventory that employs a series of true/false questions to assess various psychological conditions.
