Turkish Version of the Chalder Fatigue Scale: An Investigation of Its Psychometric Properties in Healthy Young Adults
The aim of this study was to adapt the Chalder Fatigue Scale to Turkish and to examine its psychometric properties in young adults. Within the scope of the study, firstly the Turkish version of the scale will be developed and then its reliability and validity will be examined in healthy young adults in Turkey.
Fatigue is a subjective experience that can affect all individuals. It is a protective symptom against physical or psychological stress for healthy individuals. However, it can negatively affect the performance of individuals in activities of daily living. In the clinic, fatigue is assessed by self-reported scales. Different fatigue scales have some advantages and disadvantages compared to each other. Moreover, it is stated that only one scale cannot fully measure the fatigue of individuals in different health status, therefore different scales have been developed.Chalder Fatigue Scale (CFS) is an easy-to-understand, short, fast and useful fatigue scale that evaluates fatigue with two dimensions (physical and mental) and enable individuals to express perceived fatigue clearly. Psychometric properties of CFS have been investigated in general population and different disease groups but not in only healthy young adults.
