The occurrence of neuropsychiatric sequelae is frequently observed among survivors of traumatic brain injury (TBI). These neuropsychiatric sequelae can characterize the quality of life of TBI survivors. Among these neuropsychiatric conditions, aggression and self-perception are significant because of their potential to impair survivors’ well-being. Long-term social isolation, common among TBI survivors, has also been linked with an increased likelihood of aggressive behavior. However, research investigating the effects of aggression and self-perception on quality of life of TBI survivors is limited. Thus, the purpose of this study was to explore the relationships connecting aggression and self-perception with quality of life of survivors of mild to moderate TBI. Additionally, this study examined the relationship between social isolation and aggression among this sample population. Through understanding of the neuroscientific underpinnings of TBI and its sequalae, this research can provide insights into the effectiveness of current mental health interventions and lead to improved treatment for TBI survivors. The findings of the study demonstrated that aggression, as a predictor variable, was negatively correlated with quality of life of TBI survivors. Additionally, the study revealed a positive correlation between self-perception and quality of life of TBI survivors. The findings also suggested a significant relationship between social isolation and aggression among TBI survivors. To enhance the generalizability of the study, future researchers could consider expanding the sample size to include individuals with moderate to severe TBI.
