Resilience is associated with health-related quality of life in caregivers of service members and veterans following traumatic brain injury

Purpose To examine factors related to resilience in military caregivers across caregiver health-related quality of life (HRQOL), caregiver sociodemographic variables, and service member/veteran (SMV) injury and health status. Methods Caregivers (N = 346, Female = 96.2%; Spouse = 91.0%; Age: M = 40.6 years, SD = 9.3) of SMVs following a mild, moderate, severe, or penetrating TBI were recruited from U.S. military treatment facilities and via community outreach. Caregivers completed select TBI-CareQOL and NIH Toolbox scales, the Caregiver Appraisal Scale, Caregiver Questionnaire, and Mayo-Portland Adaptability Inventory-4. Caregivers were divided into three groups using the TBI-QOL Resilience scale: (1) Low-Moderate Resilience (n = 125), (2) Moderate Resilience (n = 122), and (3) Moderate-High Resilience (n = 99). Results Factors related to low caregiver resilience were strain on employment, financial burden from out-of-pocket expenses, caring for children, less personal time, caring for both verbal and physical irritability, anger, and aggression, and lower SMV functional ability (all p's < .05). The Low-Moderate Resilience group had consistently worse HRQOL scores compared to the Moderate and Moderate-High Resilience groups (ps < .001; d = .50-1.60), with the exception of Caregiving Ideology. Conclusion Lower resilience among caregivers of SMVs following TBI is associated with poorer caregiver HRQOL. Programs aimed at promoting and maintaining resilience in military caregivers long-term is important for their own health, the health of the SMV, and the health of their children.
