Abstract:
Chronic Fatigue Syndrome is a baffling disease potentially affecting millions of Americans. Self-rating scales were developed to assess this condition but have yet to be validated with objective measures of activity. The present study of a 45-yr.-old man evaluated the relationships between scores on self-rating scales used to measure Chronic Fatigue Syndrome and actigraphy. Measured activity was related to predictors of fatigue but not to fatigue. The implications of these findings are discussed.
