Childhood Health Assessment Questionnaire - Child's Version

Instrument Name: Childhood Health Assessment Questionnaire - Child's Version

Abbreviation: CHAQ-CV

Description of Tool:

The Childhood Health Assessment Questionnaire - Child Version asks children aged 8 to 19 years to rate their ability to do functional tasks over the last week. Activities are rated as "without any difficulty," "with some difficulty," "with much difficulty," "unable to do," and "Not applicable". The tool covers 9 domains, including: Disability,
Dressing and Grooming,
Arising, Eating, Walking,
Hygiene, Reach, Grip,
Activities, and Discomfort. Scores range from 0 to 24, with lower scores representing better functional status.
