However, upon reviewing the literature, the need for evaluation of disease activity status in JIA in these aspects is reported (1, 2). Objectives: This study aimed to investigate the functionality, participation, and biopsychosocial status of individuals with JIA according to disease activity. Methods: Our study included fifty individuals (31 girls, 19 boys) diagnosed with JIA, of whom 35 had oligoarticular and 15 had polyarticular JIA, and who were followed up with routine controls. Demographic information of the participants was documented, and disease activity status was assessed using the Juvenile Arthritis Disease Activity Score in 71 joints (JADAS-71). Functionality was measured using the Childhood Health Assessment Questionnaire (CHAQ), participation was evaluated using the Child and Adolescent Scale of Participation (CASP), and biopsychosocial status was examined using the Juvenile Arthritis Biopsychosocial Questionnaire (JAB-Q). Disease activity was categorized based on the JADAS-71 score: ≤1 indicated inactive disease, while >10.5 indicated high disease activity (3). Group characteristics were compared using the Mann-Whitney U test. Results: Demographic characteristics of inactive and high disease activity JIA patients were similar (p>0.05). CHAQ pain, general well-being, and total score, CASP home participation and total score, JAB-Q-child disease activity, joint, functionality, fatigue, and total scores were significantly better in favor of the inactive group; ESR value and number of affected active joints were higher in individuals with high disease activity (p<0.05). Conclusion: This study showed that individuals with JIA exhibiting high disease activity were more affected in functionality, participation, and biopsychosocial status compared to those with inactive disease. The findings of this study suggest that these factors should be considered in the disease management of individuals with JIA starting from high disease activity.
