Family Functioning, Medical Self-Management, and Health Outcomes Among School-Aged Children With Sickle Cell Disease: A Mediation Model.

Background: Informed by the Pediatric Self-Management Model, the present study tested relationships between parent and family functioning, sickle cell disease (SCD) self-management, and health outcomes for children with SCD.

Method: 83 children with SCD and a parent completed baseline data as part of a larger investigation of a family-based, problem-solving intervention for children with SCD (M age = 8.47). Youth and parents completed a measure of child health-related quality of life (HRQOL), and parents completed measures of family efficacy, parenting stress, and SCD self-management. SCD pain episodes and urgent health utilization information over the past year were obtained via medical chart review.

Results: SCD self-management mediated the relationship between parent-reported family efficacy and parent proxy HRQOL, as well as the relationship between parenting stress and child and parent proxy HRQOL. Mediation models were nonsignificant for outcomes beyond HRQOL, including SCD pain episodes and urgent health utilization.

Conclusion: Fostering family efficacy and reducing parenting stress may be meaningful intervention targets for improving SCD self-management and child HRQOL among school-aged children. Although findings were consistent with the Pediatric Self-Management Model in terms of HRQOL, the model was not supported for pain episodes or urgent health utilization, highlighting the need for multi-method, longitudinal research on the SCD self-management behaviors that are linked to preventable health outcomes.
