Validity and reliability of the chalder fatigue scale and multidimensional assessment of fatigue in stroke

The aim of the study was to examine the psychometric properties of the Chalder Fatigue Scale (CFS) and the Multidimensional Assessment of Fatigue (MAF), which examines fatigue both physically and mentally in stroke patients, and to investigate the factors affecting fatigue in this patient group. Eighty stroke individuals between the ages of 18-80 who had a stroke for the first time were included in our study. Test-retest reliability, internal consistency and Cronbach's alpha values of both scales were examined. The test-retest application was applied for both scales with one-week intervals. For validity, the relationships of the scales with Fugl Meyer Test, Beck Depression Inventory, Stroke-Specific Quality of Life Scale, Pittsburgh Sleep Quality Index, International Physical Activity Questionnaire, Barthel Activities of Daily Living Index and Stroke Impact Scale were examined. CFS and MAF were found to have excellent test-retest reliability. When the internal consistency of the scales was examined, it was seen that CFS had acceptable internal consistency, while MAF had a suspicious level of internal consistency. When the convergent validity of the scales was examined with FSS, it was found that CFS had excellent concurrent validity and MAF had good concurrent validity. When the correlations of the scales with the FMT, BDE, SSQoL and PUKI, IPAQ, BADLI and SIS subsections were examined, it was determined that there was a correlation between the scales and the scales ranging from insignificant to excellent, and that both scales had convergent validity. As a result, it was determined that CFS and MAF are reliable and valid measurement tools that can be used in the multidimensional evaluation of fatigue in stroke patients. In addition, it was observed that there was a relationship between fatigue and age, gender and recovery stage in stroke patients.
