The purpose of this study was to examine the dyadic and individual level effects of parent and child pain catastrophizing on child health-related quality of life (HRQOL) in pediatric sickle cell disease. Questionnaires assessing child pain frequency, child and parent pain catastrophizing, and child HRQOL were completed by youth and their primary caregiver. A Common Fate Model was estimated to test the dyadic level relationship between parent and child pain catastrophizing and child HRQOL. An Actor-Partner-Common Fate Model hybrid was estimated to test the relationship between child HRQOL and individual-level child pain catastrophizing and parent pain catastrophizing, respectively. In each model, child HRQOL was modelled as a dyadic variable by factoring parent and child ratings. Patients (N = 100, M age = 13.5 years, 61% female) and their caregivers (M age = 41.8 years, 86% mothers) participated. Dyad-level pain catastrophizing was negatively associated with child HRQOL, demonstrating a large effect (β = -0.809). Individual-level parent and child pain catastrophizing were each uniquely negatively associated with child HRQOL, demonstrating small to medium effects (β = -0.309, β = -0.270). Individual level effects were net of same-rater bias, which was significant for both parents and children. Both the unique and the overlapping aspects of parent and child pain catastrophizing are significant contributors to associations with child HRQOL, such that higher levels of pain catastrophizing are associated with worse child HRQOL. Findings suggest the need for multipronged intervention targeting factors common to parent-child dyads and factors unique to parents and children, respectively.
