<h3>Background</h3> Fatigue is a common symptom in pediatric health conditions and is associated with poorer health related quality of life. (1). The Pediatric Quality of Life Inventory PedsQL™ Multidimensional Fatigue Scale (MFS) was designed by Varni and colleagues to measure fatigue in children. PedsQL-MFS is a widely used instrument to measure the disease-specific health-related quality of life summary measures in children and adolescents with arthritis (1-3). <h3>Objectives</h3> The aim of this study was to describe the cultural adaptation, validity, and reliability of a Turkish version of the PedsQL-MFS in children and adolescents with arthritis. <h3>Methods</h3> A total of 66 children (8-12 years) and adolescents (13-18 years) with arthritis and their parents were enrolled in the study. Children (n=32) and adolescents (n=34) were diagnosed with Juvenile Idiopathic Arthritis by a pediatric rheumatologist based on the ILAR diagnostic criteria. The 10 cm Visual Analog Scale (VAS)-fatigue was used to evaluate the validity of related domains in the the PedsQL-MFS. The participants rated how often a particular problem occurred in the past month, using a 5-point Likert Scale and for the young child self-report a 3-point scale. Each item is reverse-scored and rescaled to 0–100 scale, so that higher scores indicate fewer symptoms of fatigue. Both the PedsQL-MFS and 10 cm Visual Analog Scale (VAS)-fatigue were filled out by children and adolescents over 8 years of age and their parents. <h3>Results</h3> The means of ages were 9.66±1.38 for children, 15.53±1.6 for adolescents. Internal reliability was good to excellent (Cronbach9s alpha coefficients 0.86-0.91 for self-reporting and 0.83-0.91 for parent reporting). Parent–child concordance for all scores was moderate (0.49-0.57) (Table 1). The PedsQL-MFS and VAS-fatigue were highly correlated, with coefficients from -0.38 to -0.45, indicating concurrent validity. <h3>Conclusions</h3> We demonstrated the reliability and validity of fatigue measurement using the Turkish version of the PedsQL-MFS in our sociocultural context. the PedsQL-MFS can be utilized as a tool for the evaluation of fatigue in children and adolescents with JIA aged 8–18 years. <h3>References</h3> Paulo L.T., Len C.A., Hilario M.O., Pedroso S.A., Vitalle M.S., Terreri M.T.
