Psychometric properties evaluation of the childhood health assessment questionnaire (CHAQ) in Moroccan juvenile idiopathic arthritis
The objective of this study is to develop and validate a Moroccan version of the childhood health assessment questionnaire (CHAQ), a disability measure for children suffering from juvenile idiopathic arthritis. The CHAQ has been validated in a cross-sectional study in 60 JIA, classified into systemic (33%), polyarticular (38%), extended oligoarticular (6.4%), and persistent oligoarticular (21.6%) subtypes. The CHAQ was tested for reliability and construct validity by correlating the yield of the questionnaire with other disease activity parameters. Disability index was significantly different among the four JIA subtypes. CHAQ proved to be valid in clinically discriminating between healthy subjects and patients with different patterns of JIA. The convergent validity was demonstrated by strong correlations of the disability score with the JIA score set of variables. In conclusion, the Moroccan version of the CHAQ has good psychometric properties. This validated version of the Moroccan CHAQ should help to individual follow-up of children suffering from JIA.
