What is the Difference Between MMPI and MMPI 2?
🆚 Go to Comparative Table 🆚The MMPI (Minnesota Multiphasic Personality Inventory) and MMPI-2 (Minnesota Multiphasic Personality Inventory-2) are both psychological tests used to assess the personality of individuals. However, there are some key differences between the two:
- Purpose: MMPI was designed specifically for clinical psychology, while MMPI-2 can be used in other fields as well, such as industrial contexts for screening high-risk positions and in legal settings for criminal and custodial care cases.
- Publication: MMPI was published in 1942 by Starke R. Hathaway and John C. McKinley, while MMPI-2 is a revised version of the original test.
- Usage: MMPI-2 is more widely used than MMPI, especially in fields outside of clinical psychology.
- Comparability: A study comparing MMPI and MMPI-2 in the assessment of posttraumatic stress disorder (PTSD) found a high degree of association between the two tests, suggesting a high degree of comparability.
In summary, while both MMPI and MMPI-2 are psychological tests used to assess personality, MMPI-2 is a revised version of the original test and can be used in a wider range of contexts. Both tests have a high degree of comparability, especially in assessing PTSD.
Comparative Table: MMPI vs MMPI 2
The MMPI (Minnesota Multiphasic Personality Inventory) and MMPI-2 (the second version of the test) are personality assessment tools used to measure various aspects of a person's character. The MMPI-2 is an updated version of the original MMPI, with some differences and improvements. Here is a table highlighting the differences between MMPI and MMPI-2:
Feature | MMPI | MMPI-2 |
---|---|---|
Scales | 10 clinical scales | 10 clinical scales, with some changes and restructuring |
Validity Scales | Fewer validity scales | More advanced validity scales, including V, Fb, Fp, Sn, Ma, and supplementary scales |
Interpretation | Interpretation focuses on code types, with at least five T-score points between the lowest scale in the code type and the next highest clinical scale (excluding scales 5 and 0) | Restructured Clinical (RC) scales available in the MMPI-2 Extended Score Report, providing more specific and detailed information |
Development | Developed earlier | Developed later, with some changes and improvements |
Please note that the MMPI-2 is an updated version of the MMPI, and the differences mentioned above are not exhaustive. The MMPI-2 includes restructured clinical scales, which provide more specific and detailed information for interpretation, while the original MMPI uses code types for interpretation. The MMPI-2 also has more advanced validity scales compared to the original MMPI.
