Personality Assessment Inventory in Fibromyalgia: Links to Functional, Physical-Somatic, and Emotional Impact

Area of Science:

• Psychiatry
• Rheumatology
• Clinical Psychology

Background:

• Fibromyalgia (FM) is a chronic condition with widespread pain, fatigue, and psychological symptoms.
• Patients often exhibit distinct personality traits and psychopathological patterns linked to symptom severity.

Purpose of the Study:

• To investigate psychopathological profiles in fibromyalgia patients.
• To analyze these profiles based on functional, physical-somatic, and emotional impairment domains.
• To correlate profiles with cumulative disease severity.

Main Methods:

• Cross-sectional study of 70 women diagnosed with FM.
• Assessment of psychological functioning using the Personality Assessment Inventory.
• Measurement of disease impact with the Fibromyalgia Impact Questionnaire.
• Hierarchical cluster analyses to classify participants into mild and severe clusters.

Main Results:

• Severe functional impairment correlated with higher affective dysregulation and somatic complaints.
• The severe-physical cluster exhibited increased mood instability, somatization, and suicidal ideation.
• The severe-emotional cluster showed higher rates of major depression and persistent depressive disorder.
• Greater cumulative disease severity intensified depressive and somatic disorders.

Conclusions:

• Fibromyalgia presents a biopsychosocial profile where emotional distress is linked to psychological and physical symptoms.
• Findings underscore the necessity for personalized, multidisciplinary care and comprehensive assessment for fibromyalgia patients.
