Development of a fatigue scale

  [ 39 votes ]   [ 1 Comment ]
www.ProHealth.com • December 3, 1993


A self-rating scale was developed to measure the severity of
fatigue. Two-hundred and seventy-four new registrations on a
general practice list completed a 14-item fatigue scale. In
addition, 100 consecutive attenders to a general practice
completed the fatigue scale and the fatigue item of the
revised Clinical Interview Schedule (CIS-R). These were
compared by the application of Relative Operating
Characteristic (ROC) analysis. Tests of internal consistency
and principal components analyses were performed on both sets
of data. The scale was found to be both reliable and valid.
There was a high degree of internal consistency, and the
principal components analysis supported the notion of a
two-factor solution (physical and mental fatigue). The
validation coefficients for the fatigue scale, using an
arbitrary cut off score of 3/4 and the item on the CIS-R were:
sensitivity 75.5 and specificity 74.5.
