The relationship between the Overcontrolled-Hostility Scale and the MMPI 4--3 high-point pair
Journal of Clinical Psychology
|July 1, 1982
Summary
The study found that individuals with the Minnesota Multiphasic Personality Inventory (MMPI) 4--3 high-point pair showed significantly higher Overcontrolled-Hostility (O-H) scores. This finding was consistent across prison and outpatient samples.
Area of Science:
- Psychological Assessment
- Clinical Psychology
- Personality Research
Background:
- The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used psychometric tool for personality assessment.
- The Overcontrolled-Hostility (O-H) scale measures a specific pattern of emotional and behavioral regulation.
- Understanding specific MMPI scale configurations can offer insights into underlying psychological traits.
Purpose of the Study:
- To investigate the association between the MMPI 4--3 high-point pair and scores on the Overcontrolled-Hostility (O-H) scale.
- To examine this relationship across diverse clinical and non-clinical populations.
- To determine if the 4--3 high-point pair is a reliable indicator of overcontrolled hostility.
Main Methods:
- Utilized MMPI data from three distinct populations: prison inmates (N=200), psychology clinic outpatients (N=500), and a state hospital sample (N=102).
- Participants were identified as having the 4--3 high-point pair based on specific MMPI scale score criteria (Scale 4 > Scale 3 ≥ T-score 65).
- Compared O-H scale scores between individuals with the 4--3 high-point pair and matched control groups.
Main Results:
- In the prison sample, individuals with the MMPI 4--3 high-point pair exhibited significantly higher O-H scores compared to controls.
- These findings were successfully cross-validated in the psychology clinic outpatient sample, confirming the association.
- A similar trend was observed in the state hospital sample, though it did not reach statistical significance due to sample size limitations.
Conclusions:
- The MMPI 4--3 high-point pair is significantly associated with elevated Overcontrolled-Hostility (O-H) scores.
- This MMPI configuration appears to be a valid indicator of overcontrolled hostility across different populations.
- Further research with larger sample sizes may clarify the association in more restricted populations.
