Chronic Fatigue Syndrome: Cognitive, Behavioural and Emotional Processing Vulnerability Factors.
Brooks, Samantha K, Chalder, Trudie, Rimes, Katharine A · Behavioural and cognitive psychotherapy · 2017 · DOI
Quick Summary
This study looked at whether certain personality traits and thinking patterns might make someone more vulnerable to developing ME/CFS. Researchers compared 67 people with ME/CFS to 73 healthy people, asking about their personalities both now and before they became ill. They found that people who later developed ME/CFS tended to be perfectionists, were very self-sacrificing, and had unhelpful beliefs about emotions—especially before they got sick.
Why It Matters
Understanding pre-illness personality and cognitive patterns may help identify people at risk for developing ME/CFS and could inform preventative strategies or early interventions. This research bridges the gap between psychological factors and disease onset, suggesting that addressing unhelpful thinking patterns and emotional beliefs might be relevant in CFS management.
Observed Findings
CFS patients reported higher pre-morbid perfectionism compared to healthy controls, though current perfectionism levels were similar.
CFS patients showed greater self-sacrificial beliefs both currently and pre-morbidly, with the difference more pronounced before illness onset.
CFS patients reported more unhelpful beliefs about experiencing and expressing negative emotions, especially in the 6 months pre-illness.
In the 6 months before illness onset, CFS patients experienced greater disruption to primary goals and higher general stress than controls.
The extent of overinvestment in one goal was significantly associated with fatigue severity.
Inferred Conclusions
Perfectionism, self-sacrificial tendencies, unhelpful emotion-regulation beliefs, and perceived stress appear to be pre-morbid characteristics more prevalent in people who develop CFS.
Goal overinvestment and major life stress in the months preceding symptom onset may represent important vulnerability factors in CFS development.
Cognitive-behavioural models linking personality vulnerabilities to CFS are supported by retrospective evidence validated by family corroboration.
Remaining Questions
Do these psychological characteristics directly cause CFS, or do they reflect individual responses to early/prodromal illness symptoms?
What This Study Does Not Prove
This study does not prove that personality traits cause ME/CFS; it only shows these traits were more common before illness onset. The direction of causality remains unclear—stress and early illness symptoms may have influenced personality expression, rather than personality traits causing disease. Retrospective reporting introduces recall bias that could distort the accuracy of pre-illness characterizations.

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 →
