Chronic Fatigue Syndrome’s principal symptoms are severe and include
prolonged fatigue and a number of other minor symptoms.
Behavioral data collection methods were used in a case study
to show some of the benefits that can be derived from
monitoring symptoms hourly and daily. Using time series
regression, several statistically significant correlates of
fatigue were found both within days and between days.
Perceived energy, physical exertion, and mental exertion were
significantly related to fatigue in both analyses. Collection
of such data may help resolve a number of theoretical and
methodological problems in research on the Chronic Fatigue
