MMPI MMPI - Minnesota Multiphasic Personality Inventory History, Development, and Psychometric Properties Questions and Answers 2 — Questions and Answers
Question 1: The MMPI-2 normative sample of 2,600 adults was stratified to match which U.S. Census reference year?
- 1970 U.S. Census
- 1980 U.S. Census (Correct answer)
- 1990 U.S. Census
- 2000 U.S. Census
Correct answer: 1980 U.S. Census
The MMPI-2 normative sample was stratified by age, gender, ethnicity, and region to match the demographics of the 1980 U.S. Census.
Question 2: Uniform T-scores, introduced in the MMPI-2 and retained in later versions, were designed to ensure what property across scales?
- All scales have identical means and standard deviations
- Consistent percentile equivalents at corresponding T-score levels across scales (Correct answer)
- All T-scores remain below the clinical threshold of 65
- Higher internal consistency coefficients
Correct answer: Consistent percentile equivalents at corresponding T-score levels across scales
Uniform T-scores ensure that a given T-score value corresponds to the same percentile rank across all scales, a property that linear T-scores do not guarantee.
Question 3: Test-retest reliability coefficients for MMPI-2 clinical scales over short intervals generally fall in which range?
- Very low: r < .40
- Moderate to high: r = .50–.90 (Correct answer)
- Perfect: r = 1.0
- Near zero: r < .10
Correct answer: Moderate to high: r = .50–.90
MMPI-2 clinical scales demonstrate moderate to high short-interval test-retest reliability (approximately .50–.90), reflecting their measurement of relatively stable personality and psychopathology dimensions.
Question 4: The MMPI-3, the most current major revision, was published in which year?
- 2008
- 2013
- 2018
- 2020 (Correct answer)
Correct answer: 2020
The MMPI-3 was published in 2020 by Yossef Ben-Porath and Auke Tellegen, containing 335 items with fully updated norms and restructured scale architecture.
Question 5: Which psychologist made foundational theoretical contributions to actuarial MMPI code type interpretation and clinical versus mechanical prediction?
- Starke Hathaway
- Paul Meehl (Correct answer)
- James Butcher
- Irving Gottesman
Correct answer: Paul Meehl
Paul Meehl's work on clinical versus actuarial prediction and code type classification became foundational to how MMPI profiles are systematically interpreted.
Question 6: Why did Hathaway deliberately use numbers rather than diagnostic names for the original MMPI clinical scales?
- Numbers were required by APA publication standards at the time
- Scale names were classified during World War II
- To discourage simplistic diagnostic labeling since the scales had complex, multidimensional correlates (Correct answer)
- Numbers were easier to memorize for clinicians
Correct answer: To discourage simplistic diagnostic labeling since the scales had complex, multidimensional correlates
Hathaway intentionally used scale numbers to prevent clinicians from making reductive diagnostic inferences, recognizing that each scale correlated with far more than its original psychiatric category name implied.
