Symptom severity and life satisfaction in brain injury: The mediating role of disability acceptance and social self-efficacy

BACKGROUND: Although the negative impact of symptom severity on subjective well-being outcomes has been established among individuals with brain injury, the mediating and protective role that positive human traits might have on this relationship has not been adequately explored. OBJECTIVE: The purpose of this study was to examine the impact of social self-efficacy and disability acceptance on the relationship between symptom severity and life satisfaction among individuals with brain injury. METHODS: Hierarchical regression analysis and correlation techniques were used to test a hypothesized dual-mediation model of life satisfaction in a sample of 105 adults with acquired brain injury. RESULTS: Results indicated that social self-efficacy and disability acceptance fully mediated the relationship between symptom severity and life satisfaction, lending support for a dual-mediation model with disability acceptance being the strongest contributor. CONCLUSIONS: These findings suggest there may be considerable value for rehabilitation providers to develop strengths-based service strategies and/or specialized intervention programs that focus on capitalizing these positive human traits to promote life satisfaction and well-being for clients with brain injury. Implications for clinical practice and future research direction are also discussed.
