Exploring the validity of the Chalder Fatigue scale in Chronic Fatigue Syndrome (CFS)

  [ 124 votes ]   [ Discuss This Article ]
By Morriss RK, Wearden AJ, Mullis R • www.ProHealth.com • November 18, 1998


The Chalder fatigue scale is widely used to measure physical and
mental fatigue in chronic fatigue syndrome patients, but the
constructs of the scale have not been examined in this patient
sample. We examined the constructs of the 14-item fatigue
scale in a sample of 136 chronic fatigue syndrome patients
through principal components analysis, followed by
correlations with measures of subjective and objective
cognitive performance, physiological measures of strength and
functional work capacity, depression, anxiety, and subjective
sleep difficulties. There were four factors of fatigue
explaining 67% of the total variance. Factor 1 was correlated
with subjective everyday cognitive difficulties, concentration
difficulties, and a deficit in paired associate learning.
Factor 2 was correlated with difficulties in maintaining
sleep. Factor 3 was inversely correlated with grip strength,
peak VO2, peak heart rate, and peak functional work capacity.
Factor 4 was correlated with interview and self-rated measures
of depression. The results support the validity of mental and
physical fatigue subscales and the dropping of the "loss of
interest" item in the 11-item version of the fatigue scale.
