The Chilean version of the Childhood Health Assessment Questionnaire (CHAQ) and the Child Health Questionnaire (CHQ).

The aim of this study was to cross-culturally adapt and validate the Chilean parent’s version of the Childhood Health Assessment Questionnaire (1) and the Child Health Questionnaire (2) in a cohort of healthy children and in patients with juvenile idiopathic arthritis (JIA) being followed by the Chilean members of the Paediatric Rheumatology International Trials Organisation (PRINTO). This project formed a part of a larger international survey conducted by PRINTO and supported by the European Union (contract BMH4 983531 CA) (3-5) whose scope is to evaluate the health-related quality of life in children with JIA as compared to their healthy peers.
