Psychophysical distress and alexithymic traits in chronic fatigue syndrome with and without comorbid depression.
Sepede, G, Racciatti, D, Gorgoretti, V et al. · International journal of immunopathology and pharmacology · 2011 · DOI
Quick Summary
This study compared people with ME/CFS to healthy people and looked at two things: emotional distress and difficulty recognizing their own feelings. They found that ME/CFS patients had more physical symptoms and emotional complaints than healthy people, especially those who also had depression. Interestingly, even ME/CFS patients without depression had some difficulty identifying their emotions, though less than those with depression.
Why It Matters
Depression is common in ME/CFS and may worsen outcomes, yet few studies systematically assess the distinct psychometric profiles of depressed versus non-depressed ME/CFS patients. This research suggests that even without clinical depression, ME/CFS patients show measurable difficulty recognizing their emotions—a finding that could inform psychological and supportive interventions. Recognizing and treating comorbid depression appropriately may improve overall functioning and quality of life in this population.
Observed Findings
ME/CFS patients showed significantly higher somatic complaints on the SCL-90R compared to healthy controls.
Depressive and obsessive-compulsive symptoms on SCL-90R were elevated only in the depressed ME/CFS subgroup, not in non-depressed ME/CFS patients.
Non-depressed ME/CFS patients showed intermediate impairment in identifying feelings (Difficulty in Identifying Feelings subscale of TAS-20) compared to depressed patients and healthy controls.
A trend toward higher fatigue severity (FIS scores) was observed in depressed versus non-depressed ME/CFS patients.
Comorbid depression significantly increased overall psychophysical distress and alexithymic traits in ME/CFS.
Inferred Conclusions
Comorbid depression in ME/CFS substantially amplifies both psychological distress and difficulty identifying emotions compared to non-depressed ME/CFS.
Identifying and treating depression in ME/CFS patients is clinically urgent to improve social functioning and quality of life.
Alexithymia (difficulty identifying feelings) appears to be a measurable trait that may be present even in non-depressed ME/CFS patients, suggesting a distinct ME/CFS-related component independent of depression.
Remaining Questions
Is the difficulty in identifying feelings in non-depressed ME/CFS patients a direct effect of ME/CFS pathology, or does it reflect the cumulative psychological burden of chronic illness?
What This Study Does Not Prove
This study does not establish causation: it cannot determine whether depression causes worse ME/CFS symptoms, whether ME/CFS causes depression, or whether a third factor causes both. The cross-sectional design captures only a single point in time, so it cannot demonstrate how these relationships evolve over the course of illness. The findings also do not prove that alexithymia is intrinsic to ME/CFS pathology rather than a response to chronic illness stress.

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 →
