Fatigue and psychosocial variables in autoimmune rheumatic disease and chronic fatigue syndrome: A cross-sectional comparison.
Ali, Sheila, Matcham, Faith, Irving, Katherine et al. · Journal of psychosomatic research · 2017 · DOI
Quick Summary
This study compared how people with ME/CFS and people with autoimmune rheumatic diseases (like rheumatoid arthritis) experience fatigue and cope with their symptoms. The researchers found that people with ME/CFS were more fatigued, had worse sleep, and were more likely to avoid activities and struggle with accepting their illness, while people with rheumatic diseases were more likely to worry about damage to their bodies. This suggests that fatigue in these different conditions may need different treatment approaches.
Why It Matters
Understanding how ME/CFS differs from other fatiguing conditions in terms of psychological responses and coping patterns is crucial for developing targeted treatments. This study provides evidence that avoidance and lack of acceptance may be particularly important factors in ME/CFS fatigue, potentially informing psychological intervention design specifically suited to ME/CFS rather than applying strategies from rheumatic disease treatment.
Observed Findings
The CFS group reported significantly higher fatigue severity than the combined ARD group after adjusting for age and illness duration.
The CFS group showed worse sleep quality and greater social adjustment difficulties compared to those with rheumatic diseases.
After adjusting for fatigue, CFS patients scored higher on lack of acceptance and avoidance/resting behaviours.
ARD patients reported significantly higher levels of catastrophizing, damage beliefs, and symptom-focusing than CFS patients.
No statistically significant differences were found between the three ARD subgroups (RA, SpA, CTD) on any measured variables.
Inferred Conclusions
Fatigue in rheumatic diseases may be perpetuated by similar underlying transdiagnostic processes despite diagnostic differences.
Lack of acceptance and avoidance behaviours may be particularly important perpetuating factors specific to CFS fatigue.
Treatment approaches should be tailored to the distinct psychosocial profiles of CFS versus ARD, rather than using one-size-fits-all fatigue interventions.
Psychosocial factors appear to play different roles in these conditions and warrant condition-specific therapeutic targeting.
Remaining Questions
What This Study Does Not Prove
This cross-sectional design cannot establish causality—it cannot prove whether lack of acceptance and avoidance cause worse ME/CFS fatigue or result from it. The study also does not measure post-exertional malaise (PEM), a hallmark ME/CFS symptom, so it cannot determine whether avoidance patterns in ME/CFS relate specifically to PEM-triggered symptom exacerbation. Differences in psychosocial profiles may reflect differences in disease biology rather than differences in psychological processes.

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 →
Does avoidance and reduced acceptance drive worse outcomes in ME/CFS, or do these psychological responses develop as a result of severe fatigue and its consequences?
How do these psychosocial profiles relate to objective physiological markers or ME/CFS-specific symptoms like post-exertional malaise?
What is the temporal relationship between these psychological factors and fatigue severity—could interventions targeting acceptance and activity patterns be effective in ME/CFS?
How do these findings translate into practical treatment recommendations, and which specific interventions should be adapted for ME/CFS patients?
