Responsiveness of the PedsQL to pain-related changes in health-related quality of life in pediatric sickle cell disease.

ABSTRACT

OBJECTIVE: To determine if caregiver report of the pediatric quality of life inventory (PedsQL) is responsive to changes in health-related quality of life (HRQL) associated with pain episodes in pediatric sickle cell disease (SCD). METHODS: 81 caregivers of children ages 2-19 years with SCD completed the PedsQL as part of routine psychosocial screenings at 2 time points, ranging from 6 to 18 months apart. Frequency of SCD-related pain episodes between time points was assessed using medical chart review. RESULTS: The frequency of pain episodes between time points was a significant predictor of decreases in physical, psychosocial, and total HRQL, even after controlling for time interval, demographic, and medical variables. CONCLUSIONS: The caregiver report of the PedsQL appears to be a useful tool for capturing changes in HRQL over time associated with pain episodes in SCD.
