A prospective study of the role of coping and family functioning in health outcomes for adolescents with sickle cell disease.

Risk-and-resistance models identify factors that predict psychosocial adjustment to pediatric chronic illness, including sickle cell disease (SCD), but have not been applied to understand health outcomes. The study objectives were to examine prospectively the relationship of coping and family functioning with health outcomes for adolescents with SCD, accounting for sociodemographic and psychosocial risk. Forty-one adolescents and their families (41 primary caregivers, 9 second caregivers, and 15 healthy siblings) completed paper-and-pencil measures of coping and family functioning at a baseline assessment (time 1). At both time 1 and time 2 (1 y later), disease severity, SCD complications, healthcare utilization, and average hemoglobin level were derived from medical file reviews. Time 1 disease-related parenting stress predicted time 2 health outcomes; however, there were no significant associations for coping. Families concordant in reporting lower family functioning had teens with increased disease severity and greater healthcare utilization. Examination of moderation of disease-related parenting stress by a risk index showed main effects for risk and for disease-related parenting stress for time 2 disease severity and time 2 healthcare utilization. Interaction effects were not significant. Efforts to explore specific mechanisms by which adaptive family functioning contributes to health outcomes for adolescents with SCD should continue, with particular attention to addressing the potential role of multiple sociodemographic and psychosocial risk variables.
