Fibromyalgia characterization in a psychosocial approach

Area of Science:

• Psychology
• Rheumatology
• Health Sciences

Background:

• Fibromyalgia is a complex chronic pain condition.
• Understanding patient heterogeneity is crucial for effective management.
• The interplay between personality, psychopathology, and health in fibromyalgia requires further investigation.

Purpose of the Study:

• To characterize fibromyalgia patients based on personality, psychopathology, health status, and potentially traumatic life events (PTLE).
• To explore the relationships between these factors and identify distinct patient profiles.
• To assess the role of PTLE in the development of fibromyalgia.

Main Methods:

• A sample of 50 women diagnosed with fibromyalgia was assessed.
• Variables included disability, physical and mental health, pain, PTLE (childhood and life course), and personality.
• Multiple correspondence analysis and K-Means cluster analysis were employed.

Main Results:

• Two distinct patient profiles emerged: 'Better adjustment' (n=36) with better health and fewer psychopathological issues, and 'Disorder and disability' (n=14) with poorer health and more personality problems.
• Personality analysis revealed three profiles (normal, neurotic, psychopathological), with the normal profile being most prevalent (n=22).
• Personality demonstrated a stronger association with physical health than PTLE.

Conclusions:

• Fibromyalgia patient population is heterogeneous, necessitating individualized treatment approaches.
• There is a significant link between personality traits and physical health outcomes in fibromyalgia.
• Potentially traumatic life events played a less significant role than anticipated in this cohort.
