Complications that can arise from sickle cell disease (SCD) have the potential to negatively affect health-related quality of life (HRQL). SCD manifests in varying degrees of severity, but effects on HRQL are not uniform. Cognitive abilities influence HRQL in other pediatric groups, potentially through variability in treatment adherence and psychological coping. This study examined the effect of SCD severity on HRQL and explored cognitive abilities as a moderator of this relationship. ⋯ Cognitive factors modify the effect of SCD severity on HRQL, particularly among youth with milder forms of SCD. Future studies are warranted to clarify the role of cognitive abilities in determining HRQL. Clinicians should monitor youth with milder forms of SCD and limited cognitive abilities for worsening HRQL and opportunities to provide support around disease self-management.
