This study looked at whether people with ME/CFS have certain personality traits that might be connected to their illness. Researchers gave a personality questionnaire to 38 people with ME/CFS and 42 healthy people, and found that those with ME/CFS scored higher on two traits: being cautious about potential harm and being persistent in their efforts. The findings suggest that these personality characteristics might play a role in how ME/CFS develops or continues.
Understanding whether specific personality traits are associated with ME/CFS could help explain why some people develop or maintain the illness, and might inform psychotherapy approaches. If these traits play a role in disease perpetuation, targeted interventions addressing them could potentially improve patient outcomes.
This study cannot prove that these personality traits cause ME/CFS—it only shows an association. The cross-sectional design means we cannot determine whether these personality characteristics existed before illness onset or developed as a result of living with ME/CFS. The study also cannot rule out that both the personality traits and CFS share a common underlying biological cause.
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 →
