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.
