Abstract

Background/Objective The importance of patient-reported outcomes, like the Patient-Reported Outcomes Measurement Information System (PROMIS) measures, is increasingly recognized both in clinical care and in research. While "short forms"have been studied in juvenile idiopathic arthritis (JIA), study of PROMIS computer adaptive tests (CATs) in JIA is limited. This cross-sectional study evaluates whether PROMIS CATs correlate with disease activity in patients with JIA. Methods A convenience sample of patients with JIA (N = 44) was recruited from a single center. Patients and parents completed pediatric and parent proxy PROMIS CATs. Disease activity was evaluated using the Juvenile Arthritis Disease Activity Score in 71 joints (JADAS-71) and the Childhood Health Assessment Questionnaire (CHAQ). Correlation of the CAT T scores with disease activity was assessed using Spearman correlation coefficients. Results Forty-four of 80 eligible subjects (29 patients and 15 parents) completed all or some PROMIS CATs. Pain interference and mobility CATs correlated moderately with JADAS-71. Nearly all correlations with the JADAS-71 were weakened when the patient global was removed. Pain interference, mobility, and fatigue were strongly correlated with the CHAQ. Among parent proxy CATs, only mobility and depressive symptoms correlated strongly with the CHAQ. Conclusions Only pain interference and mobility PROMIS CATs showed strong correlation with standard disease activity measures in JIA, and nearly all correlations were weakened when the patient global was removed. Correlations of the CATs with the CHAQ were stronger than correlations with the JADAS-71, indicating that although the CHAQ is no longer routinely used it may be a better measure of health-related quality of life in routine clinical care.
