The relationship between cumulative risk and health‐related quality of life in youth with sickle cell disease: Moderating effects of secondary control engagement coping

Abstract

BackgroundYouth with sickle cell disease (SCD) often experience low health‐related quality of life (HRQOL). Engagement in resilience‐promoting processes, such as secondary control engagement (SCE) coping, or adapting to stressors, may be linked to contextual risk factors (e.g., poverty status). This study aims to illuminate relationships between a cumulative risk index (CRI), SCE coping, and HRQOL in youth with SCD and test whether SCE coping moderates the relationship between CRI and HRQOL.ProcedureParticipants in this cross‐sectional study included 63 youth ages 8–18 with SCD. Participants completed measures to assess SCE coping use (Responses to Stress Questionnaire) and HRQOL (PedsQL SCD Module). Six variables from the electronic medical record were compiled in a CRI. Correlational and regression analyses examined relationships between primary variables and moderating effects of SCE coping, respectively.ResultsModel results show that SCE coping and CRI explain variation in HRQOL (p = .001), and a significant interaction exists between SCE and CRI (β = −.29, p = .02), with a stronger inverse relationship between CRI and HRQOL for higher SCE values. This suggests that lower CRI is associated with greater HRQOL for those with higher SCE coping relative to lower SCE coping.ConclusionsSCE coping may selectively benefit children with SCD experiencing lower cumulative risk, warranting encouragement of this strategy in clinical settings. Findings do not support SCE coping benefits for youth with higher risk, suggesting that the strategy may not be useful when risk‐related stressors are especially pervasive; alternative protective factors should be identified for this risk group.
