Child Health Questionnaire (CHQ)

The Child Health Questionnaire is a generic, parent-reported instrument developed by Landgraf et al. in 1996 to measure health-related quality of life in children aged 5–18 years. Unlike disease-specific measures, the CHQ captures broad domains of physical, emotional, social, and school functioning, making it suitable for diverse pediatric populations with or without chronic conditions. The CHQ-50 is the most widely used parent-report form; shorter (CHQ-28) and comprehensive (CHQ-CF87 child + family) versions are also available.
