Sickle cell disease (SCD) is associated with pain and decreased health-related quality of life (HRQOL). Coping strategies influence pain but have not been evaluated as mediating the relation between pain and HRQOL in pediatric SCD. The current study examined whether pain-related coping mediates the association between pain and HRQOL in children and adolescents with SCD. In total, 104 children and adolescents 8 to 18 years of age (Mage=12.93 y) with SCD attending outpatient clinics completed pain intensity, HRQOL, and pain-related coping measures. Multiple mediation analyses were used to examine whether pain-related coping mediated the pain and HRQOL relation and whether types of coping (ie, approach, emotion-focused avoidance, problem-focused avoidance) were independent mediators. Total indirect effects for models examining physical and psychosocial HRQOL were not significant.

After controlling for covariates, emotion-focused avoidance significantly mediated the association between pain and physical HRQOL (effect: -0.023; bootstrapped SE: 0.018; 95% confidence interval: -0.0751, -0.0003) but not the pain and psychosocial HRQOL relation. Approach and problem-focused avoidance were not significant mediators. Coping with pain in pediatric SCD is an important avenue for clinical intervention and additional research. Among children with SCD reporting high pain intensity, interventions should emphasize negative impacts of emotion-focused avoidance coping and integrate other empirically supported coping strategies to improve HRQOL.
