Journal of Clinical Psychology
|April 1, 1976
Summary
This study found that most male inpatient alcoholics have diverse MMPI profiles, not matching the average. This suggests significant heterogeneity in personality characteristics among individuals with alcoholism.
Area of Science:
- Psychiatry
- Clinical Psychology
- Addiction Medicine
Background:
- Alcoholism is a complex condition often studied using psychological assessments.
- The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used tool for personality assessment.
Purpose of the Study:
- To analyze the heterogeneity of MMPI two-point codes in a large sample of male inpatient alcoholics.
- To explore the relationship between MMPI profiles and personality characteristics in this population.
Main Methods:
- Examination of MMPI two-point codes from 1,009 male Caucasian inpatient alcoholics.
- Statistical analysis to compare individual profiles against the mean profile.
Main Results:
- The mean MMPI profile was 4-2.
- However, 79% of individual profiles differed significantly from the mean.
- Frequently occurring MMPI codetypes were linked to diverse behavioral descriptions.
Conclusions:
- Male inpatient alcoholics represent a heterogeneous group regarding MMPI profiles.
- This heterogeneity extends to underlying personality characteristics.
