Adaptation of HAQ for children with juvenile idiopathic arthritis (Singh 1994). 30 items across 8 domains; rates difficulty in past week (0 = without difficulty, 3 = unable). The disability index is the mean of the highest score per domain (0–3). This calculator returns the sum (0–24) — divide by 8 for disability index.
