Criticism[edit | edit source]
- There is no post-exertional malaise (PEM) required for diagnosis, which sets it apart from Canadian Consensus Criteria, International Consensus Criteria, and Systemic Exertion Intolerance Disease criteria (IOM Criteria).
- Letter by Tom Kindlon criticising the criteria, "Criteria used to define chronic fatigue syndrome questioned", that was published in Psychosomatic Medicine 
- One research study found 38% of those with a diagnosis of a Major depressive disorder were misclassified as having CFS using the empirical/Reeves definition.
