We studied the relative responsiveness of the VAS<jats:sub>CHAQ<\/jats:sub> as compared to the original CHAQ-30 and revised CHAQ-38, as well as the parent-patient, physician-patient, and physician-parent concordance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods.<\/jats:title><jats:p>The CHAQ-38 and VAS<jats:sub>CHAQ<\/jats:sub> were administered to 30 parents and patients (if older than 8 years) with any subtype of JIA before and after the start of a new treatment.
