This study looked at whether certain personality traits are more common in people with ME/CFS. Researchers compared 113 people with ME/CFS to people without it and found that those with ME/CFS had higher rates of certain personality patterns (like being more anxious or withdrawn) and personality disorders. However, these personality differences were not unique to ME/CFS—they also appeared in other chronically ill groups.
Understanding whether personality factors contribute to ME/CFS development or persistence could inform psychological interventions and help clinicians recognize behavioral patterns that might interfere with treatment. The finding that personality disorders are elevated in ME/CFS but not uniquely so raises important questions about whether these traits are a cause, consequence, or correlate of chronic illness.
This cross-sectional design cannot establish causation—it cannot determine whether certain personality traits increase ME/CFS risk, whether having ME/CFS shapes personality over time, or whether both stem from a common underlying biological process. The study also does not prove that personality features are responsible for ME/CFS maintenance, only that they correlate with it. The elevated personality disorder rates in the ISF group suggest these patterns may reflect chronic unwellness generally rather than ME/CFS specifically.
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 →
