Assessment of outcome and quality of life in children with hydrocephalus should attempt to obtain the perspective of the children themselves, when possible. Although we have developed the Hydrocephalus Outcome Questionnaire (HOQ) for parents, the aim of this study was to assess the scientific properties of a child-completed version of the HOQ (cHOQ) and compare child and parent responses in a select group of older, higher-functioning children with hydrocephalus.
Materials and methods
All children with previously treated hydrocephalus and between 10 and 18 years old attending the neurosurgery out-patient clinic at Hospital for Sick Children (Sick Kids), Toronto were asked to participate, if their parents felt they were cognitively capable of completing the cHOQ. The parents then completed the HOQ and the Health Utilities Index, while the child completed the cHOQ. The children were also asked to complete the cHOQ again, approximately 2 weeks later. Reliability coefficients were calculated and comparisons were made between parent HOQ and child cHOQ responses.
A total of 154 children participated (mean age 14.3 years, SD 2.4). Their mean cHOQ Overall Health score was 0.79 (on a scale of 0 = worst outcome to 1.0 = best outcome), SD 0.14. For the cHOQ Overall Health score, the internal consistency reliability was 0.92 and the test-retest reliability was 0.87 (95% CI 0.79–0.92). Mother-child agreement and father-child agreement were 0.67 and 0.74, respectively. Agreement was higher for assessments of physical health, but lower for assessments of cognitive health and social-emotional health. When there was disagreement, it seemed that children tended to rate their health better than their parents did.
In a select group of older children with hydrocephalus, the cHOQ appears to be a scientifically reliable means of assessing long-term outcome and quality of life. Agreement with parental responses was reasonably good for physical health, but poorer for cognitive and social-emotional health, with parents generally providing a relative underestimate of quality of life. The differences in child and parent perception of health need to be appreciated when conducting outcome studies in this population.
