Medical Post-Traumatic Stress Disorder Symptoms in Children and Adolescents with Chronic Inflammatory Arthritis: Prevalence and Associated Factors

Background: Youth with chronic rheumatologic diseases undergo medical experiences that can lead to post-traumatic stress disorder (PTSD). Understudied in pediatric rheumatology, medical PTSD can be significantly distressing and impairing. Objective: This study explored the prevalence of medical PTSD symptoms in youth with chronic inflammatory arthritis and associated factors, including pain, disease activity, mental health history, and anxiety sensitivity. Methods: A cross-sectional study of 50 youth (ages 8–18) with juvenile idiopathic arthritis (JIA) and childhood-onset systemic lupus erythematous (cSLE) was conducted at a pediatric rheumatology clinic. Participants completed self-report measures assessing post-traumatic stress symptoms (CPSS-V), pain, anxiety sensitivity (CASI), pain-related self-efficacy (CSES), adverse childhood experiences (ACEs), and fibromyalgia symptoms (PSAT). Clinical data included diagnoses, disease activity, treatment history, and demographics. Results: Forty percent had trauma symptoms in the moderate or more severe range. The 14% likely meeting criteria for probable medical PTSD were older (median 17 vs. 15 years, p = 0.005), had higher pain scores (median 4 vs. 3, p = 0.008), more ACEs (median 3 vs. 1, p = 0.005), higher anxiety sensitivity scores (median 39 vs. 29, p = 0.008), and higher JIA disease activity scores (median cJADAS-10 11.5 vs. 7.5, p = 0.032). They were also more likely to report a history of depression (71 vs. 23%, p = 0.020). No associations were found with hospitalization or injected/IV medication use. Conclusions: Medical trauma symptoms are prevalent in youth with chronic inflammatory arthritis. Probable PTSD was associated with pain and psychological distress. These findings support the need for trauma-informed care in pediatric rheumatology.
