The validity and reliability of the Juvenile Arthritis Functional Assessment Report (JAFAR) in children/adolescents with Juvenile Idiopathic Arthritis: The Turkish version study

The aim of the study was to describe validity and reliability Turkish version Juvenile Arthritis Functional Assessment Report (JAFAR) in children/adolescents with Idiopathic (JIA). Sixty-nine JIA were included study. JAFAR(TR)-Child Parent forms applied patients their parents for test retest at one-week intervals, did not receive additional treatment his/her pharmacological change that week. Test-retest evaluated by intraclass correlation coefficient (ICC), internal consistency multi-item subscales calculating Cronbach's alpha coefficient. Correlations between Pediatric Quality Life Inventory 3.0. Module (PedsQL), Childhood Health Questionnaire (CHAQ), Disease Activity Score (JADAS) determine construct validity. ICC value test/retest 0.963 JAFAR(TR)-Parent 0.576. total score had low moderate correlations PedsQL Child (r=-0.34; p=0.004), CHAQ (r=0.40; p=0.001), JADAS (r=0.42; p=0.000). high (r=-0.55; p=0.000), (r=0.72; p=0.000) (r=0.53; p= 0.000). JAFAR found be clinically valid reliable JIA.
