MMPI behavioral correlates of spike-5 and two-point code types with scale 5 as one elevation

Area of Science:

• Psychiatry
• Psychological Assessment
• Clinical Psychology

Background:

• The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used psychological assessment tool.
• Understanding MMPI profile patterns is crucial for accurate psychiatric diagnosis.
• Previous research has explored various MMPI scale elevations and their correlates.

Purpose of the Study:

• To determine base rates for MMPI profiles in a student outpatient psychiatric population.
• To investigate the relationship between specific MMPI two-point code types involving Scale 5 and psychopathology.
• To compare the correlates of Scale 5-elevated profiles with the general MMPI profile population.

Main Methods:

• Extraction and summarization of data from 550 student outpatient psychiatric files.
• Grouping of MMPI profiles based on highest two-point elevations or single elevations above T-score 70.
• Exclusion of profiles with Scale 5 as the sole or one of the two highest elevations for comparative analysis.

Main Results:

• Spike-5 MMPI profiles were associated with basically normal adjustment.
• MMPI profiles such as 2-5/5-2, 4-5/5-4, 7-5/5-7, and 8-5/5-8 indicated varying degrees of psychopathology.
• Correlates of Scale 5-elevated profiles differed from the remainder of the profile population.

Conclusions:

• MMPI Scale 5 plays a significant role in differentiating between normal adjustment and psychopathology in student psychiatric populations.
• Specific MMPI two-point code types involving Scale 5 are indicative of distinct psychological states.
• Further research can refine the interpretation of MMPI profiles for clinical applications.
