MMPI - Minnesota Multiphasic Personality Inventory Test History and Development Questions and Answers — Questions and Answers
Question 1: The original development of the Minnesota Multiphasic Personality Inventory (MMPI) by Hathaway and McKinley was distinct from other personality tests of its time primarily due to its reliance on which test construction method?
- Factor analysis
- Empirical criterion keying (Correct answer)
- Content validation
- Projective hypothesis
Correct answer: Empirical criterion keying
The MMPI was developed using empirical criterion keying. This method involves selecting items that are endorsed differently by a criterion group (e.g., individuals with a specific psychiatric diagnosis) and a control group, regardless of the item's apparent content. This atheoretical approach distinguished it from tests based on specific personality theories or rational content selection.
Question 2: A major impetus for the revision of the original MMPI into the MMPI-2 in 1989 was the need to:
- Incorporate a new theoretical model of personality.
- Shorten the test to reduce administration time.
- Update and expand the normative sample to be more representative of the U.S. population. (Correct answer)
- Create a version specifically for adolescent populations.
Correct answer: Update and expand the normative sample to be more representative of the U.S. population.
A primary criticism of the original MMPI was that its normative sample, collected in the 1930s, was not representative of the broader U.S. population. The MMPI-2 restandardization project aimed to create new norms based on a larger, more diverse, and geographically representative sample.
Question 3: Which of the following best describes the original 'criterion' groups used by Hathaway and McKinley to develop the clinical scales of the MMPI?
- College students from the University of Minnesota.
- Randomly selected adults from the Minneapolis phone book.
- Military personnel being screened for service.
- Psychiatric patients at the University of Minnesota hospital with specific diagnoses. (Correct answer)
Correct answer: Psychiatric patients at the University of Minnesota hospital with specific diagnoses.
The clinical scales of the original MMPI were constructed by identifying items that were answered differently by specific groups of psychiatric patients at the University of Minnesota hospital compared to a control group of non-patients (often visitors at the hospital). Each clinical scale was keyed to a different diagnostic group (e.g., patients diagnosed with depression for the Depression scale).
Question 4: A psychologist is reviewing a historical case file from 1995 and notes an MMPI was administered. Based on the year, which version of the test was most likely used?
- MMPI-2 (Correct answer)
- MMPI
- MMPI-3
- MMPI-A
Correct answer: MMPI-2
The MMPI-2 was published in 1989 and became the standard version, replacing the original MMPI. The MMPI-A (for adolescents) was published in 1992, and the MMPI-3 was released much later in 2020. Therefore, in 1995, the MMPI-2 would have been the most current and widely used version for adults.
Question 5: The development of the MMPI-2-Restructured Form (MMPI-2-RF) was primarily driven by a desire to address which psychometric concern with the original clinical scales?
- Outdated item content and language.
- The need for a shorter test administration time.
- High intercorrelation among the scales and item overlap. (Correct answer)
- The lack of validity scales to detect response bias.
Correct answer: High intercorrelation among the scales and item overlap.
A significant issue with the original MMPI and MMPI-2 clinical scales was their high intercorrelation and overlapping items, which limited their discriminant validity. The development of the Restructured Clinical (RC) scales, which form the basis of the MMPI-2-RF, was a major effort to create more distinct and psychometrically refined scales by removing a general distress factor (demoralization).
Question 6: The most recent version of the instrument, the MMPI-3, published in 2020, introduced several changes. Which of the following was a key goal of this revision?
- To switch from a true/false format to a Likert scale.
- To remove all validity scales from the profile.
- To introduce new scales assessing constructs like compulsivity, impulsivity, and disordered eating. (Correct answer)
- To merge the adult and adolescent versions into a single test.
Correct answer: To introduce new scales assessing constructs like compulsivity, impulsivity, and disordered eating.
The development of the MMPI-3 included updating norms and items, but also focused on introducing new scales to assess clinically relevant constructs not covered by previous versions. These new scales include Eating Concerns (EAT), Compulsivity (CMP), Impulsivity (IMP), and Self-Importance (SFI).
