Depression, attribution style and self-esteem in chronic fatigue syndrome and fibromyalgia patients: is there a link?
Michielsen, H J, Van Houdenhove, B, Leirs, I et al. · Clinical rheumatology · 2006 · DOI
Quick Summary
This study looked at whether people with ME/CFS and fibromyalgia who blame external factors (rather than themselves) for problems are protected from depression. Researchers surveyed 85 patients and found that depression was common in both single diagnosis (ME/CFS only) and dual diagnosis (ME/CFS + fibromyalgia) groups. Blaming external factors did not prevent depression in patients with low self-esteem, suggesting that how we think about our situation may not be a key factor in whether we develop depression.
Why It Matters
Depression is highly prevalent in ME/CFS populations but its mechanisms are poorly understood. This study highlights that depression in ME/CFS may not be primarily explained by how patients attribute their illness, suggesting clinicians should screen for and address depression as a significant clinical concern regardless of patients' psychological coping styles.
Observed Findings
High prevalence of depression was observed in both ME/CFS-only and ME/CFS+FM patient groups.
Minimal statistically non-significant differences were found between single and double diagnosis groups on depression, attribution style, and self-esteem measures.
External attribution style did not buffer against depression in patients with low self-esteem.
Mediation analysis failed to satisfy the four Baron and Kenny conditions needed to establish mediation.
Inferred Conclusions
External attribution style is not a protective factor against depression in ME/CFS or ME/CFS+FM patients with low self-esteem.
Depression is a highly prevalent clinical feature in both ME/CFS and comorbid ME/CFS+FM that warrants clinical attention.
Having fibromyalgia comorbidity does not substantially alter the psychological profile regarding depression, attribution, and self-esteem in ME/CFS patients.
Remaining Questions
What factors do mediate the relationship between self-esteem and depression in ME/CFS populations?
Why is depression so prevalent in ME/CFS, and what are effective interventions for addressing it?
Does attribution style play a different role in depression outcomes when examined longitudinally rather than cross-sectionally?
What This Study Does Not Prove
This study does not prove that attribution style has no relationship to depression in ME/CFS—only that it does not mediate the self-esteem to depression link in this specific analysis. The cross-sectional design prevents establishing causation. The findings cannot explain why depression rates are so high or identify what does protect or increase depression risk in these patients.
