Treatments for chronic fatigue syndrome and the Internet: a systematic survey of what your patients are reading.
Kisely, Stephen R · The Australian and New Zealand journal of psychiatry · 2002 · DOI
Quick Summary
Researchers looked at what information about ME/CFS treatments people were finding on the Internet in 2000. They found that most websites did not provide balanced or accurate information compared to what scientific research actually shows. Only a few websites told readers to check the information with their doctor, and many lacked proper author credentials or sources.
Why It Matters
This study highlights a critical gap in health literacy for ME/CFS patients: most readily available Internet information is not evidence-based. Understanding the quality and reliability of online resources helps patients make informed decisions about treatment options and empowers them to critically evaluate health information they encounter.
Observed Findings
Agreement between websites and systematic reviews ranged from 4% to 68%, with graded exercise and rest avoidance showing the greatest agreement
64% of websites had a named author, but only 25–33% declared conflicts of interest
Only 25–33% of sites advised readers to clarify information with a healthcare professional
Only 25–33% avoided making inaccurate statements
6.3% of identified websites were inaccessible during the review period
Inferred Conclusions
The Internet contains substantial ME/CFS treatment information that is neither balanced nor evidence-based
Doctors and the medical profession should actively guide patients toward trustworthy online resources
Improved transparency (authorship, conflicts of interest, references) and professional oversight are needed to improve online health information quality
Remaining Questions
How has the quality and balance of ME/CFS information on the Internet changed since 2000?
Which specific treatment recommendations were most frequently inconsistent with evidence-based practice?
What This Study Does Not Prove
This study does not assess whether patients actually followed the misinformation found online or experienced harm. It also reflects information available in 2000 and does not address how Internet content quality or search engine algorithms have evolved since then. The cross-sectional design cannot establish causation or long-term impact.
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 →
