title: The measurement of fatigue: a new instrument.
abstract: Fatigue is a frequent medical symptom which has not been routinely measured. We present a 29-item fatigue assessment instrument, describe its psychometric properties, and use it to differentiate normal fatigue from fatigue related medical disorders. Differences in fatigue across a variety of medical disorders, the reproducibility of the fatigue instrument, and its convergent validity with other fatigue measures are also described.
