Reliability, acceptability, validity and responsiveness of the CHU9D and PedsQL in the measurement of quality of life in children and adolescents with overweight and obesity
Authors' conclusion
PedsQL and CHU9D overall demonstrated good psychometric properties, supporting their use in measuring HRQoL in paediatric overweight and obesity. CHU9D had poorer responsiveness and did not discriminate between overweight and healthy weight in boys, which may limit its use in economic evaluation.
Study context
- Population
- Children aged 10–17 years, Longitudinal Study of Australian Children; weight and height measured objectively
- Participants
- 6,544 children
- Comparison
- PedsQL vs CHU9D in measuring health-related quality of life (HRQoL) by weight status
- Outcome
- Reliability, acceptability, validity and responsiveness of PedsQL and CHU9D in measuring HRQoL
Methodological detailslongitudinal, up to 3 repeated measures
- Longitudinal
- Up to 3 repeated measures
Performance
As reported in the abstract
Psychometric properties of PedsQL and CHU9D
- Both PedsQL and CHU9D: good internal consistency reliability and high acceptability
- Neither instrument showed strong convergent validity
- PedsQL appears superior to CHU9D in known groups validity and responsiveness
