This study compared personality traits between 44 people with ME/CFS and 44 healthy people without the illness. Researchers measured perfectionism (setting very high standards), self-esteem (how people value themselves), and emotional control. People with ME/CFS showed higher levels of perfectionism and lower self-esteem, but emotional control was similar between groups.
Understanding personality factors in ME/CFS may help identify psychological patterns that contribute to illness development and persistence, potentially informing more targeted psychological interventions. This work bridges psychosocial research and ME/CFS phenotyping, contributing to biopsychosocial illness models.
This study does not prove that perfectionism or low self-esteem cause ME/CFS, as personality traits were measured after illness onset—causation cannot be established from a cross-sectional comparison. The study cannot distinguish whether these personality differences preceded the illness, developed as a consequence of living with ME/CFS, or both. It does not address the biological mechanisms underlying ME/CFS.
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 →
