290. COMPARABILITY OF PROXY, ADOLESCENT AND ADULT MEASURES OF FUNCTIONAL ABILITY IN ADOLESCENTS WITH JUVENILE IDIOPATHIC ARTHRITIS

Abstract

Conclusion: There was good concordance and similar associations between the P-CHAQ, A-CHAQ and HAQ both at initial presentation to rheumatology and improvement over the first year in adolescents with JIA. The strong relationship between the HAQ and either CHAQ tool indicate the utility of HAQ in adolescents with JIA. 290 Table 1.Comparisons of the P-CHAQ, A-CHAQ and HAQ in adolescents with JIAScoreMedian baseline score (IQR)ComparisonCoefficient for baseline association (95% CI)Coefficient for improvement over the first year (95% CI)HAQ0.5 (0.0, 1.1)vs A-CHAQ0.9 (0.8, 0.9)0.8 (0.7, 0.9)A-CHAQ0.6 (0.1, 1.3)vs P-CHAQ0.9 (0.8, 1.0)1.0 (0.8, 1.1)P-CHAQ0.6 (0.1, 1.4)vs HAQ0.9 (0.8, 1.0)0.8 (0.7, 1.0)Multivariate models adjusted for age and sex, with improvement models also including baseline scores
