Area of Science:

• Psychological Assessment

Background:

• The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used psychological test.
• The Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM-III) is a standard classification of mental disorders.

Purpose of the Study:

• To examine the relationship between MMPI high-point codes and DSM-III diagnoses.
• To provide a narrative summation for each identified MMPI code type.

Main Methods:

• Five psychiatrists reanalyzed patient records (N = 261) from a private psychiatric clinic.
• DSM-III diagnoses were rendered for each patient.
• MMPI high-point codes were identified and analyzed in relation to diagnoses.

Main Results:

• Twenty-four distinct MMPI high-point code types were identified.
• Clusters of diagnostic classifications were presented for each code type.
• Narrative summations were provided for each code type.

Conclusions:

• The study establishes correlations between specific MMPI high-point codes and DSM-III diagnostic categories.
• This research aids in the interpretation of MMPI results for clinical diagnosis.
