Underlying self-esteem in chronic fatigue syndrome.
Creswell, Cathy, Chalder, Trudie · Journal of psychosomatic research · 2002 · DOI
Quick Summary
This study looked at whether people with ME/CFS have low self-esteem, using two different types of tests. When asked directly, people with ME/CFS reported lower self-esteem than healthy people and those with other chronic illnesses. However, a special test that measures unconscious reactions suggested their true underlying self-esteem was even lower than what they reported, possibly because they use mental defense mechanisms to protect themselves.
Why It Matters
This research highlights that people with ME/CFS may experience deeper psychological challenges than they consciously report, which could affect treatment approaches and psychological support strategies. Understanding the gap between conscious and unconscious self-perception may help clinicians develop more targeted interventions for this population.
Observed Findings
CFS participants reported significantly lower self-esteem on overt measures compared to healthy controls and chronic illness controls.
The Emotional Stroop Test showed greater interference (slower reaction times) for negative trait words compared to positive trait words in CFS participants.
The magnitude of interference on the negative-word Stroop was larger than could be explained by the participants' overt self-esteem reports alone.
Implicit (unconscious) processing measures revealed self-esteem deficits not fully captured by explicit self-report questionnaires.
Inferred Conclusions
People with ME/CFS possess underlying low self-esteem that is more extensive than what they consciously acknowledge or report.
Rigidly held psychological defense mechanisms may mask or suppress conscious awareness of underlying negative self-perception.
Information-processing measures (implicit tests) are necessary to fully characterize self-esteem in ME/CFS populations and should complement traditional self-report methods.
The discrepancy between implicit and explicit self-esteem measures suggests a dissociation in how self-perception is processed in CFS.
Remaining Questions
Are the defense mechanisms identified protective (helping patients function) or harmful (delaying processing of emotional distress)?
What This Study Does Not Prove
This study does not prove that low self-esteem causes ME/CFS or that it is a primary driver of the illness; the cross-sectional design cannot establish causality. It also does not establish whether the defense mechanisms identified are adaptive, maladaptive, or a direct consequence of living with chronic illness rather than an underlying trait.

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 →
