What does the HAQ-DI measure?

HAQ-DI assesses 8 categories: dressing, arising, eating, walking, hygiene, reach, grip, and activities. Each category scores 0 (no difficulty) to 3 (unable to do). Score = mean of highest scores per category (0–3).

What HAQ-DI change is clinically meaningful?

The minimum clinically important difference (MCID) for HAQ-DI is 0.22 points. HAQ-DI ≥1.0 indicates significant disability. A HAQ-DI reduction to <0.5 indicates minimal residual disability.
