Score interpretation

No Disability (CHAQ-DI 0) 0

No functional disability reported.

→ Continue routine review.

Functional Disability (CHAQ-DI > 0) 0.125–3

Higher = worse (maximum 3). Parent-rated median scores (Dempster 2001): mild disability 0.13, mild-to-moderate 0.63, moderate 1.75. A fall of 0.13 is the minimal clinically important improvement.

→ Interpret with disease activity (e.g. JADAS); physiotherapy, occupational therapy and school support as needed.
