Insights
The Pediatric Quality of Life Inventory (PedsQL) 4.0 is a feasible, reliable, and valid tool for measuring pediatric population health. This measure can effectively assess health outcomes for children in health insurance programs.
Area of Science:
- Pediatric Health Outcomes
- Health Services Research
- Quality of Life Measurement
Background:
- Health-related quality of life (HRQOL) is crucial for pediatric population health assessment.
- HRQOL measures aid in risk stratification, resource allocation, and identifying health disparities.
- Tracking community health and intervention outcomes relies on robust HRQOL data.
Purpose of the Study:
- To assess the feasibility, reliability, and validity of the PedsQL 4.0 Generic Core Scales.
- To determine the suitability of PedsQL 4.0 for measuring pediatric population health in children and adolescents.
- To evaluate PedsQL 4.0's utility for children enrolled in the State's Children's Health Insurance Program (SCHIP).
Main Methods:
- A statewide mail survey was conducted in California in February-March 2001.
- The survey targeted 20,031 families with children aged 2-16 years, including new SCHIP enrollees.
- The 23-item PedsQL 4.0 Generic Core Scales were completed by 10,241 families.
Main Results:
- The PedsQL 4.0 demonstrated minimal missing responses and excellent reliability (child alpha=.89, parent alpha=.92).
- The instrument effectively differentiated between healthy children and those with chronic health conditions.
- PedsQL 4.0 scores correlated with healthcare access, school absenteeism, and illness-related days missed.
Conclusions:
- The PedsQL 4.0 is a feasible, reliable, and valid measure for pediatric population health outcomes.
- Measuring pediatric HRQOL using PedsQL 4.0 can effectively evaluate the health outcomes of SCHIP enrollees.
- The findings support the use of PedsQL 4.0 for population health surveillance and program evaluation in pediatric populations.
Background:
The application of health-related quality of life (HRQOL) as a pediatric population health measure may facilitate risk assessment and resource allocation, the tracking of community health, the identification of health disparities, and the determination of health outcomes from interventions and policy decisions.
Objective:
To determine the feasibility, reliability, and validity of the 23-item PedsQL 4.0 (Pediatric Quality of Life Inventory) Generic Core Scales as a measure of pediatric population health for children and adolescents.
Design:
Mail survey in February and March 2001 to 20 031 families with children ages 2-16 years throughout the State of California encompassing all new enrollees in the State's Children's Health Insurance Program (SCHIP) for those months and targeted language groups.
Methods:
The PedsQL 4.0 Generic Core Scales (Physical, Emotional, Social, School Functioning) were completed by 10 241 families through a statewide mail survey to evaluate the HRQOL of new enrollees in SCHIP.
Results:
The PedsQL 4.0 evidenced minimal missing responses, achieved excellent reliability for the Total Scale Score (alpha =.89 child;.92 parent report), and distinguished between healthy children and children with chronic health conditions. The PedsQL 4.0 was also related to indicators of health care access, days missed from school, days sick in bed or too ill to play, and days needing care.
Conclusion:
The results demonstrate the feasibility, reliability, and validity of the PedsQL 4.0 as a pediatric population health outcome. Measuring pediatric HRQOL may be a way to evaluate the health outcomes of SCHIP.
