Social problem-solving skills as a mediator between executive function and long-term social outcome following paediatric traumatic brain injury.

There is debate regarding the relationship between executive function and social outcome following paediatric traumatic brain injury (TBI), due to inconsistent findings in the literature. It has been suggested that these contradictory results may reflect the absence of an established mechanism to explain this relationship. Yeates and colleagues (2004) proposed a possible model in which the maturity of social problem-solving skills mediates the relationship between executive function and social outcome. The current study aimed to explore this model and determine whether social problem solving mediates the relationship between executive function and social outcome in a TBI population. The sample consisted of 36 adolescents and young adults who sustained a TBI between 8 and 12 years of age. They ranged between 16 and 22 years of age and were 7-10 years post-injury. Findings indicated that a higher level of executive dysfunction was associated with less sophisticated social problem-solving skills and poorer social outcome. Further, the maturity of social problem-solving skills was found to mediate the relationship between executive function and social outcome in this group.
