Implication of invalidation concept in fibromyalgia diagnosis

Area of Science:

• Rheumatology
• Pain Medicine
• Social Psychology

Background:

• Fibromyalgia (FM) is a complex condition often accompanied by polysymptomatology.
• The role of social pain and perceived invalidation in FM diagnosis is under-recognized.
• Understanding social pain's impact is crucial for a comprehensive approach to FM.

Purpose of the Study:

• To investigate the effectiveness of perceived invalidation in discriminating between fibromyalgia (FM) and non-FM chronic pain patients.
• To identify specific sources of invalidation that are most predictive of FM.
• To explore the diagnostic utility of social pain in the context of fibromyalgia.

Main Methods:

• 207 chronic pain patients were assessed for FM using rheumatologic evaluation.
• The Illness Invalidation Inventory (3*I) measured perceived invalidation from various sources.
• Receiver operator characteristic (ROC) and logistic regression analyses were employed to assess discriminatory power.

Main Results:

• Patients with FM reported higher levels of discounting and lack of understanding from spouses and family compared to non-FM patients.
• Invalidation from spouse and family sources significantly discriminated between FM and non-FM groups.
• Family discounting (OR 2.30) and spousal lack of understanding (OR 1.72) were significant predictors of FM.

Conclusions:

• Perceived invalidation, particularly from family and spouses, holds significant discriminatory power for identifying fibromyalgia.
• These findings support the inclusion of invalidation as a key component in the understanding and diagnosis of FM.
• Acknowledging social pain in FM diagnosis may shift the clinical paradigm for this condition.
