MMPI Comparative Analysis MMPI-2 vs MMPI-3 Quiz 1 — Questions and Answers
Question 1: How many items does the MMPI-3 contain compared to the MMPI-2?
- MMPI-3: 567; MMPI-2: 338
- MMPI-3: 335; MMPI-2: 567 (Correct answer)
- Both 567
- Both 338
Correct answer: MMPI-3: 335; MMPI-2: 567
The MMPI-3 has 335 items vs MMPI-2's 567, substantially reducing administration time while maintaining clinical coverage.
Question 2: The MMPI-3 normative sample differs from MMPI-2's how?
- Same 1989 sample
- Updated sample better reflecting current U.S. demographics (Correct answer)
- No normative sample
- Census-matched from same year
Correct answer: Updated sample better reflecting current U.S. demographics
The MMPI-3 uses an updated sample better representing current U.S. demographic diversity, addressing MMPI-2 sample criticisms.
Question 3: What happened to original clinical scales (1-0) in the MMPI-3?
- Retained unchanged
- Replaced by RC scales as primary clinical scales (Correct answer)
- Doubled in length
- Removed without replacement
Correct answer: Replaced by RC scales as primary clinical scales
The MMPI-3 replaced original clinical scales with RC scales, reflecting their better discriminant validity and focused construct measurement.
Question 4: MMPI-3 K-correction compared to MMPI-2?
- Stronger K-correction
- Eliminates K-correction entirely (Correct answer)
- Identical procedures
- K-correction on all scales
Correct answer: Eliminates K-correction entirely
The MMPI-3 eliminates K-correction entirely, following the MMPI-2-RF precedent based on evidence it didn't consistently improve prediction.
Question 5: The primary structural difference between MMPI-2 and MMPI-3 scale systems?
- MMPI-2 hierarchical, MMPI-3 not
- MMPI-3 uses systematic hierarchy (H-O, RC, SP, PSY-5); MMPI-2 uses overlapping systems (Correct answer)
- Identical structures
- MMPI-3 has fewer total scales
Correct answer: MMPI-3 uses systematic hierarchy (H-O, RC, SP, PSY-5); MMPI-2 uses overlapping systems
MMPI-3 has a systematic hierarchical structure with clear levels, while MMPI-2 has overlapping clinical, content, and supplementary systems.
Question 6: How does MMPI-3 readability compare to MMPI-2?
- MMPI-3 requires higher reading level
- MMPI-3 written at lower reading level for improved accessibility (Correct answer)
- Identical reading levels
- MMPI-3 requires no reading
Correct answer: MMPI-3 written at lower reading level for improved accessibility
MMPI-3 items were written at a lower reading level, improving accessibility for those with lower education or limited English proficiency.
