Attributions in chronic fatigue syndrome and fibromyalgia syndrome in tertiary care.
Neerinckx, E, Van Houdenhove, B, Lysens, R et al. · The Journal of rheumatology · 2000
Quick Summary
This study looked at what 192 patients with ME/CFS, fibromyalgia, or chronic pain believed was causing their illness. Most patients thought their condition had both physical causes (like a virus or chemical imbalance) and emotional causes (like stress). The researchers found that patients' beliefs about what caused their illness were quite varied, and these beliefs did not differ much based on their specific diagnosis.
Why It Matters
Understanding how ME/CFS and fibromyalgia patients perceive the causes of their illness is crucial for developing effective treatment strategies and improving the patient-clinician relationship. This study reveals that most patients hold mixed physical-psychological beliefs about their condition, suggesting that treatment approaches should address multiple causal frameworks rather than imposing a single explanatory model.
Observed Findings
70% of patients mentioned both physical and psychosocial causes; 48 patients attributed illness to physical causes only; 10 patients attributed illness to psychosocial causes only
61% reported belief in chemical imbalance; 51% reported belief in viral etiology; 61% reported stress as causal; 40% reported emotional confusion as causal
Diagnostic label (CFS vs FM vs CPF) did not significantly influence number or type of attributions
Patients with symptoms >1 year and those with self-help group contact showed stronger external, stable, and global attributions
Small-to-moderate effect sizes found between specific attributions and symptom duration, self-help group contact, and premorbid depression
Inferred Conclusions
Most ME/CFS and fibromyalgia patients hold diverse, multifactorial illness attributions that are not strongly determined by formal diagnosis, suggesting a need for personalized rather than protocolized cognitive-behavioral approaches
Patients with longer symptom duration and self-help group involvement warrant special clinical attention due to attributional patterns that may undermine self-efficacy
Cognitive-behavioral interventions should be tailored to individual causal beliefs rather than assuming a unified attribution across the patient population
Remaining Questions
Do patients' illness attributions change over time, and if so, what drives these changes?
What This Study Does Not Prove
This study does not establish what actually causes ME/CFS or fibromyalgia—only what patients believe causes their symptoms. The cross-sectional design cannot determine whether attributions are a cause or consequence of symptom duration and self-help group involvement, and correlation between attributions and depression does not imply causation. The study was conducted in a tertiary care setting, so findings may not generalize to primary care or untreated populations.

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 →
What is the causal relationship between symptom duration/self-help group contact and the development of global, external attributions—does duration lead to attributional shift, or do certain attributions arise first and persist?
How do different illness attributions affect treatment outcomes, engagement, and psychological functioning in ME/CFS and fibromyalgia?
Which cognitive-behavioral interventions are most effective for patients with different attribution patterns?
