Juvenile idiopathic arthritis (JIA) is the primary rheumatic disease reported to affect the pediatric population. Research suggests that parents' thoughts and feelings about their child's pain, specifically with JIA diagnosis, may influence treatment compliance. Considering that this situation may also affect children's adherence to treatment, the identification and management of parents' catastrophizing of pain is emphasized as important in improving treatment outcomes. This study aimed to examine the biopsychosocial characteristics of parents of children diagnosed with JIA according to their reported catastrophizing of pain.
