Objective: Caregiver resilience in the context of childhood cancer treatment has been described using cross‐sectional and retrospective studies, but little is known about prospective predictors of resilience outcomes. We examined associations of demographics, cancer‐related variables, and intrapersonal and interpersonal factors at diagnosis (family psychosocial risk, perceived social support, and healthcare self‐efficacy) and psychosocial services provided during treatment with caregiver resilience outcomes at the end of treatment.
