When does a difference make a difference? MMPI scores and African-Americans

Area of Science:

• Psychological assessment
• Cultural psychology
• Psychometrics

Background:

• The Minnesota Multiphasic Personality Inventory (MMPI) is widely used in psychological assessment.
• Previous research on MMPI group differences has often overlooked significant methodological issues.
• Interpretations of MMPI profiles for African-Americans require careful consideration of cultural factors.

Purpose of the Study:

• To re-examine MMPI literature concerning African-Americans.
• To identify major methodological issues in existing research.
• To question traditional interpretations of African-American MMPI profiles.

Main Methods:

• Systematic review of MMPI literature focusing on African-American samples.
• Analysis of criteria for ethnic/racial group membership and socioeconomic status.
• Examination of cultural variance in MMPI item content and scale elevations.

Main Results:

• Significant methodological issues were identified in MMPI research relevant to African-Americans.
• Cultural variance in MMPI item content and scale elevations is evident in African-American samples.
• The magnitude of cultural variance varies across samples and is significant for individuals with developing cultural identity.

Conclusions:

• Traditional scientific methods and interpretations of MMPI profiles for African-Americans are questionable due to methodological flaws.
• Cultural variance significantly impacts MMPI results for African-Americans.
• Future research should address these methodological concerns and consider cultural identity in MMPI interpretation.
