Tom Kindlon questions the definition of recovery, arguing that entry criteria can be virtually the same as recovery criteria. Our baseline data1 show very severely fatigued and impaired adolescents, not even close to the cutoff points for recovery. We determined normal ranges on the basis of our own sample of healthy peers, which is a control group that is healthier than average: all children with a medical or mental disorder were excluded.2 Theoretically, a patient might only change from -21SD at inclusion to -1-9 SD after treatment, but analyses showed that not a single case merely "crossed the border".
