Resilience and social support as factors associated with quality of life among family caregivers of patients with traumatic brain injury: a cross-sectional study

Purpose: This study aimed to examine the associations of resilience and social support with multidimensional quality of life (QoL) among family caregivers of patients with traumatic brain injury (TBI).Methods: This single-center, cross-sectional descriptive study used questionnaire data collected at a regional trauma center in Korea. Family caregivers of patients with TBI (n=122) were recruited by convenience sampling. The questionnaires assessed participants’ general characteristics, resilience, perceived social support, and QoL.Results: Multiple regression analysis showed that higher resilience was associated with greater QoL burden in the vigilance, emotional suppression, and feeling trapped domains. In contrast, higher social support was associated with lower QoL burden in the strain, anxiety, emotional suppression, feeling trapped, feeling of loss (self), and family disruption domains, but with greater QoL burden in the feeling of loss (with TBI) domain.Conclusion: Resilience and social support were associated with multidimensional QoL among family caregivers of patients with TBI. Strategies to improve caregiver well-being should include targeted psychological support and interventions that strengthen resilience within existing social support systems.
