Associations between perfectionism, mood, and fatigue in chronic fatigue syndrome: a pilot study.
Blenkiron, P, Edwards, R, Lynch, S · The Journal of nervous and mental disease · 1999 · DOI
Quick Summary
This study looked at whether people with ME/CFS who tend to be perfectionists experience different levels of fatigue, anxiety, or depression compared to healthy people. Researchers found that people with ME/CFS actually had lower perfectionism scores than healthy controls, and were less likely to set high standards for others. Interestingly, this lower expectation of others was linked to less physical fatigue.
Why It Matters
This research challenges the common assumption that perfectionism drives ME/CFS symptoms, suggesting instead that patients may adapt by lowering their expectations. Understanding these personality patterns could inform psychological approaches to rehabilitation and help clinicians avoid misconceptions about perfectionism as a primary driver of illness.
Observed Findings
Other-oriented perfectionism scores were significantly lower in CFS patients compared to healthy controls (p = .0019)
Other-oriented perfectionism correlated negatively with physical fatigue across all participants (R = -0.27, p = .02)
Women with CFS showed particularly lower other-oriented perfectionism scores
Total perfectionism scores did not correlate with fatigue, anxiety, or depression in either group
Total and socially prescribed perfectionism correlated with age in the CFS group only (p = .05)
Inferred Conclusions
CFS patients may set lower standards and expectations for others compared to healthy individuals
The association between perfectionism and CFS may be more complex than previously theorized, with lower rather than higher perfectionism potentially relevant
Personality changes in CFS patients may represent adaptation to illness rather than a predisposing trait
Rehabilitation approaches might benefit from considering how patients' lowered expectations for others affect recovery
Remaining Questions
Why do CFS patients show lower other-oriented perfectionism, and is this a pre-illness trait or an adaptation to living with the disease?
What This Study Does Not Prove
This study does not establish that perfectionism causes or worsens ME/CFS fatigue—the observed negative correlation between other-oriented perfectionism and fatigue is the opposite of what this hypothesis would predict. The small sample size and cross-sectional design cannot determine whether lower perfectionism is a cause, consequence, or unrelated characteristic of ME/CFS. No causal relationships can be inferred from correlational data.
