Validity and reliability of functional assessment of chronic illness treatment-fatigue scale in Turkish patients with type 2 diabetes

Abstract

BackgroundA long-term diabetic complication, fatigue, which is a direct result of treatment and psychological processes, is a common symptom in diabetic individuals. AimsTo determine the reliability and validity of Functional Assessment of Chronic Illness Treatment-Fatigue Scale in Turkish patients with type 2 diabetes. Study designA methodological study. MethodsThe sample consisted of 133 patients with type 2 diabetes who agreed to participate in the study and met the criteria for the study. Data were collected using the descriptive information form prepared by the researcher and the Scale obtained from FACIT System. The research data were collected by face-to-face interviews with the patients. Language and content validity of the Turkish version of the Scale was provided, Cronbach's Alpha coefficient, test–retest analysis and item analysis methods were used as reliability analysis. ResultsThe total Cronbach Alpha coefficient of the scale was found to be 0.92. According to the results of factor analysis, unlike the original scale, two sub-dimensions emerged in the Turkish version of the scale. ConclusionsAs a result of the validity and reliability analysis of the FACIT-Fatigue Scale, it can be said that it provides psychometric measures that can be used to determine the level of fatigue of type 2 diabetes patients in Turkish society.
