Relationships of self-awareness and facial affect recognition to social communication ability in persons with traumatic brain injury.

Traumatic brain injury (TBI) can cause changes to the injured person's physical ability, cognitive functioning, and social interactions. Since these attributes largely determine a person's concept of who they are, TBI poses a threat to sense of self. Due to the importance of social communication skills for community integration, impairment of these skills is a particular threat to sense of self. The present investigation sought to explore characteristics that influence social communication abilities. We hypothesized that both ability to interpret facial affect and self-awareness would be associated with communication ability. We also expected that facial affect recognition would influence self-awareness and that the effect of facial affect recognition on social communication would be partially mediated by self-awareness. For this prospective cohort study, participants were 77 individuals with documented TBI. Of these, 65% were male and 83% sustained severe injuries. The hypothesized association of facial affect recognition with social communication was demonstrated with path analysis as was the effect of facial affect recognition on self-awareness. However, the effect of facial affect recognition on social communication was not mediated by self-awareness. In addition, social communication was associated with employment, social integration, and loneliness. Findings highlighted the importance of social communication after TBI.
