The role of self-appraisal of cognitive function in predicting psychosocial outcome following traumatic brain injury

Individuals who sustain a traumatic brain injury (TBI) can experience changes in their physical, cognitive, and emotional status (Cifu, Kreutzer, Marwitz, Rosenthal, Englander, & High, 1996). Adjustment to these changes varies, with a number of interacting factors, including age, injury severity, psychological variables, and occupational status influencing outcome (Stratton & Gregory, 1994). Given the multitude of symptoms often experienced by the TBI survivor, it is perhaps surprising that individuals may not always be aware of such impairment. There is support that lack of awareness into disability may impede rehabilitation efforts and result in poor adjustment post-trauma (Prigatano, 1991). While a subset of individuals appears to minimize impairment, there is evidence to suggest that individuals with milder injuries may demonstrate exaggerated statements of impairment. However, no researcher has yet investigated the impact of symptom overreport on psychosocial outcome.; The aim of the proposed study was to examine the extent to which self-appraisal of cognitive function was predictive of psychosocial outcome following TBI. It was hypothesized that accurate appraisal of cognition would predict better adjustment in terms of interpersonal relationships, independent living, and occupational status following TBI. Results from the investigation lent partial support for this hypothesis, although obtained effect sizes were small. Findings are discussed in the context of how they relate to previous research and future implications.
