Piper Fatigue Scale (PFS)
The four-dimensional fatigue scale (Behavioral / severity, Emotional,
Sensory and Cognitive) consists of 27 items. Items 2-23 are calculated
as eleven points out of which the total average score is based between
0-10. The higher score denotes higher level of fatigue. In addition,
five end items are included for enrichment of the questionnaire, which
are not calculated. Reliability of this tool was confirmed in the study
by [18] with Pearson correlation coefficient as
0.08. In the current research, correlation was confirmed as 0.80 using
Cronbach’s alpha.
