Final answer:
The MCMI-IV differs from the MMPI-2 in it being designed specifically for clinical populations and based on Theodore Millon's theories, whereas the MMPI-2 is for a general population and uses true/false questions and scale-based scoring.
Step-by-step explanation:
The MCMI-IV (Millon Clinical Multiaxial Inventory-IV) and the MMPI-2 (Minnesota Multiphasic Personality Inventory-2) are both widely used personality assessments but differ in specific ways. Firstly, the MCMI-IV is designed specifically for clinical populations and is based on Theodore Millon's personality theories, which categorizes disorders into broader personality patterns. In contrast, the MMPI-2 is designed for a more general population and is used for various purposes including clinical diagnosis, occupational screening, and counseling. Secondly, the format and item count differ between the two instruments; the MCMI-IV has fewer questions and utilizes a base rate score system, while the MMPI-2 contains 567 true/false questions and scores are interpreted based on scales.
