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

We report herein the results of the cross-cultural adaptation and validatio n into the Czech language of the parent's version of two health related qua lity, of life instruments. The Childhood Health Assessment Questionnaire (C HAQ) is a disease specific health instrument that measures functional abili ty in daily, living activities in children with juvenile idiopathic arthrit is (JIA). The Child Health Questionnaire (CHQ) is a generic health instrume nt designed to capture the physical and psychosocial wellbeing of children independently from the underlying disease. The Czech CHAQ-CHQ were fully, v alidated with 3 forward and 3 backward translations. A total of 150 subject s were enrolled: 81 patients with JIA (14% systemic onset, 44% polyarticula r onset, 10% extended oligoarticular subtype, and 32% persistent oligoartic ular subtype) and 69 healthy children. The CHAQ clinically, discriminated b etween healthy, subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy, peers . Also the CHQ clinically, discriminated between healthy, subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoar ticular subtypes having a lower physical and psychosocial well-being when c ompared to their healthy, peers. In conclusion the Czech version of the CHA Q-CHQ is a reliable, and valid tool for the functional, physical and psycho social assessment of children with JIA.
