    ObjectivesThe objective was to investigate the serial mediating effects of perceived cognitive functioning, patient health communication, and disease-specific worry in the relationship between pain and overall generic health-related quality of life (HRQOL) in youth with sickle cell disease (SCD) from the patient perspective.MethodsThe pain, cognitive functioning, communication and worry scales from the Pediatric Quality of Life Inventory (PedsQL) Sickle Cell Disease Module and the PedsQL Multidimensional Fatigue Scale, and the PedsQL 4.0 Generic Core Scales were completed in a multisite national study by 233 youth with SCD of ages 5-18. Hierarchical multiple regression and serial multiple mediator model analyses were conducted to test the mediating effects of perceived cognitive functioning, health communication, and disease-specific worry as intervening variables in the association between the pain predictor variable and overall generic HRQOL.ResultsPain predictive effects on overall generic HRQOL were serially mediated by cognitive functioning, health communication, and disease-specific worry. In predictive analytics models utilizing hierarchical multiple regression analyses with age and gender demographic covariates, pain, cognitive functioning, health communication, and worry accounted for 65% of the variance in patient-reported overall generic HRQOL (P < .001), representing a large effect size.ConclusionsPerceived cognitive functioning, patient health communication, and disease-specific worry explain in part the mechanism of pain predictive effects on overall generic HRQOL in youth with SCD. Identifying SCD-specific pain, perceived cognitive functioning, health communication, and disease-specific worry as predictor variables of overall generic HRQOL from the patient perspective may inform clinical interventions and future patient-centered clinical research.© 2020 Wiley Periodicals LLC.
