F Scale elevation and PTSD MMPI profiles

Area of Science:

• Psychological Assessment
• Clinical Psychology
• Military Mental Health

Background:

• Posttraumatic Stress Disorder (PTSD) significantly impacts veteran mental health.
• The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used tool for psychological assessment.
• Understanding MMPI profiles in PTSD populations is crucial for accurate diagnosis and treatment.

Purpose of the Study:

• To classify and analyze MMPI profiles of veteran inpatients diagnosed with PTSD.
• To investigate the relationship between F Scale elevation and MMPI profile configurations.
• To identify common MMPI two-point code types across different F Scale elevation levels.

Main Methods:

• Analysis of MMPI profiles from 87 veteran inpatients with PTSD.
• Classification of profiles based on F Scale elevation levels.
• Examination of mean MMPI profiles and frequency of high two-point code types.

Main Results:

• For F Scale elevation greater than or equal to 70, MMPI Scales 2 and 8 were the highest clinical scales.
• When F Scale elevation was below 70, Scale 8 was not among the two highest clinical scales.
• The 2-8/8-2 high two-point code was the most frequent for the entire sample, with variations across F Scale levels.

Conclusions:

• F Scale elevation is a significant factor influencing MMPI profile interpretation in PTSD veterans.
• Distinct MMPI patterns emerge at different F Scale thresholds, affecting the prominence of key clinical scales.
• These findings aid in refining the interpretation of MMPI results for veterans with PTSD.
