Summary
The computerized adaptive Minnesota Multiphasic Personality Inventory-2 (MMPI-2) shows high similarity to the standard version. This adaptive testing method offers substantial item savings for psychological assessments.
Area of Science:
- Psychological Assessment
- Psychometrics
- Computerized Adaptive Testing
Background:
- The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a widely used psychological assessment tool.
- Evaluating the comparability of different administration formats is crucial for test validity and user efficiency.
Purpose of the Study:
- To assess the comparability between the computerized adaptive version and the standard version of the MMPI-2.
- To determine the efficiency gains in terms of item administration with the adaptive format.
Main Methods:
- Administered both the computerized adaptive MMPI-2 and the standard MMPI-2 to 155 college students, one week apart.
- Utilized the countdown method for adaptive administration of specific MMPI-2 scales (L, F, 10 clinical scales, 15 content scales).
Main Results:
- Psychometric profiles generated by both versions demonstrated a high degree of similarity.
- The adaptive testing approach resulted in significant item savings compared to the standard version.
Conclusions:
- The computerized adaptive MMPI-2 is comparable to the standard version, supporting its use in psychological evaluations.
- Adaptive testing with the MMPI-2 offers practical advantages through reduced item administration, warranting further investigation.
