In the Chicago population based study, 40.6% were employed full time, 12.5% part time and the rest were unemployed/receiving disability income or retired. So perhaps more like 60-65% of CFS patients in general. Keeping in mind that the main 'improvement' was lower symptom reporting, rather than improved activity levels or neuropsychiatric testing. Also keeping in mind that GET as delivered by these clinics still has an underlying positive cognitive focus (eg patients are more optimistic) and it is this that mediates the change in questionnaire reporting in both arms. The APT focus was more realistic hence why the reporting looked poorer.
