Summary
This study found sex differences in personality traits measured by the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Men scored higher on antisocial and Type A traits, while women scored higher on health-related and emotional scales.
Area of Science:
- Psychology
- Psychometrics
Background:
- The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used psychological assessment tool.
- Understanding sex differences in personality is crucial for accurate interpretation of assessment results.
Purpose of the Study:
- To compare sex differences on the MMPI-2 with previously established differences on the MMPI-1.
- To identify specific scales where significant sex differences emerge on the MMPI-2.
Main Methods:
- A comparative analysis was conducted on MMPI-2 scores from male (n=66) and female (n=132) participants.
- Mean raw scale scores were analyzed for statistically significant sex-based variations.
Main Results:
- Men exhibited higher mean scores on scales measuring antisocial behavior, authority problems, addiction admission, amorality, and Type A personality.
- Women demonstrated higher mean scores on Hypochondriasis, Depression, Hysteria, Paranoia, and somatic complaint scales.
Conclusions:
- The MMPI-2 reveals distinct sex differences in personality profiles, largely consistent with MMPI-1 findings.
- These findings underscore the importance of considering sex as a factor in MMPI-2 interpretation.
