Alexithymia in chronic fatigue syndrome: associations with momentary, recall, and retrospective measures of somatic complaints and emotions.
Friedberg, Fred, Quick, Joyce · Psychosomatic medicine · 2007 · DOI
Quick Summary
This study looked at whether difficulty identifying and expressing emotions (a trait called alexithymia) is linked to fatigue and pain in ME/CFS patients. Researchers asked 111 people with ME/CFS to report their symptoms three ways: in real-time through daily diaries, in weekly recall, and in overall retrospective ratings over 6 months. The results showed that day-to-day emotional difficulty was not connected to how patients experienced symptoms moment-to-moment, but there was a weak connection to how they remembered pain over longer periods.
Why It Matters
Understanding whether emotional processing difficulties drive ME/CFS symptoms could inform psychological treatment approaches. By using multiple measurement methods including real-time symptom tracking, this study provides a more nuanced picture of how psychological factors relate to ME/CFS than prior retrospective-only research, helping clarify which symptom reports are most affected by emotional factors.
Observed Findings
No significant associations between alexithymia (general or specific dimensions) and momentary fatigue or pain ratings in electronic diaries.
A specific form of alexithymia was significantly associated with retrospective pain measures.
Anxiety partially mediated the relationship between alexithymia and retrospective pain.
Physical illness attribution showed no significant association with alexithymia.
Results differed substantially between momentary and retrospective symptom measurement approaches.
Inferred Conclusions
Alexithymia is at best a modest predictor of somatic symptoms in ME/CFS and shows measurement-dependent associations (stronger with retrospective than momentary assessment).
The disconnect between momentary and retrospective findings suggests that recall bias or long-term illness appraisal, rather than ongoing emotional processing difficulty, may account for alexithymia associations with pain.
Psychological factors like emotional awareness may play a limited role in ME/CFS symptom generation.
Anxiety may be a more relevant mediator than alexithymia for understanding symptom-emotion relationships in this population.
Remaining Questions
Why do alexithymia associations appear only in retrospective but not momentary measures—is this due to memory effects, reporting bias, or fundamentally different mechanisms?
What This Study Does Not Prove
This study does not prove that alexithymia causes ME/CFS symptoms or that psychological interventions targeting emotional awareness will improve fatigue and pain in ME/CFS patients. The cross-sectional design cannot establish causality, and the modest associations found do not support alexithymia as a primary driver of somatic symptoms in this population.

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 →
