Personality and social attitudes in chronic fatigue syndrome.
Wood, B, Wessely, S · Journal of psychosomatic research · 1999 · DOI
Quick Summary
This study compared personality traits and attitudes between people with ME/CFS and people with rheumatoid arthritis (RA) to see if ME/CFS patients have distinctive personality characteristics. Researchers found that ME/CFS patients and RA patients were actually quite similar in most personality measures, and the common stereotype that ME/CFS patients are perfectionists with negative views about psychiatry was not supported.
Why It Matters
This study challenges the persistent misconception that ME/CFS is primarily a psychological disorder caused by perfectionism or psychiatric resistance. By demonstrating that ME/CFS patients have similar personality profiles to RA patients with a chronic illness, it supports the biological nature of ME/CFS and may help reduce stigma. Understanding that social difficulties in ME/CFS relate primarily to functional limitations rather than personality pathology has implications for treatment approaches.
Observed Findings
No significant differences between ME/CFS and RA groups on perfectionism, attitudes toward mental illness, defensiveness, social desirability, or sensitivity to punishment
ME/CFS patients had significantly worse social adjustment and reported greater activity restriction and relationship difficulties (p<0.001)
RA patients had paradoxically higher alexithymia (difficulty identifying emotions) scores than ME/CFS patients (p<0.05)
Poor social adjustment in ME/CFS was strongly associated with depressive symptoms but remained statistically significant after adjusting for depression
Inferred Conclusions
ME/CFS and RA patients do not differ significantly in personality traits, contradicting the stereotype of CFS patients as distinctive perfectionists
The social difficulties observed in ME/CFS are primarily due to functional limitations and depression rather than underlying personality pathology
Personality-based explanations for ME/CFS etiology lack empirical support from this comparative analysis
Remaining Questions
Why did RA patients show higher alexithymia scores than ME/CFS patients, contrary to expectations?
How do these findings generalize to different ME/CFS populations and diagnostic criteria used today?
What This Study Does Not Prove
This study does not prove that psychological factors play no role in ME/CFS pathophysiology or symptom expression. As a cross-sectional design, it cannot establish causation or determine whether observed personality traits preceded or resulted from illness. The study was conducted in 1999 with relatively small sample sizes, and findings may not generalize to all ME/CFS populations or diagnostic criteria used today.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
