Longitudinal use of the Child Health Questionnaire in childhood cerebral palsy

This study sought to describe change and stability in health‐related quality of life (HRQL) over time in a cross‐section of children with cerebral palsy (CP) using the Child Health Questionnaire (CHQ) through repeated surveys of the children's parents/caregivers. A total of 177 children with CP (98 males, 79 females); age range 3 to 18 years (mean age 8y 6mo, [SD 4y 2mo]; Gross Motor Function Classification System: Level I 40%, Level II 14%, Level III 14%, Level IV 16%, and Level V 17%) were enrolled as a convenience sample from the outpatient clinics at a tertiary‐care children's hospital. The main outcome measure was HRQL as determined by the CHQ — Parent Form 50. Parents reported reduced HRQL for their children with CP relative to norms for the CHQ. Although Role — Physical functioning (reflecting how physical impairment interferes with daily activity) declined with time, all other subscales of the CHQ were stable over the course of 1 year. CHQ scores were not measurably affected by common medical interventions. Children with CP have lower CHQ scores than other children that are, on average, stable over the course of 1 year.
