Are the subjective complaints of traumatically brain injured patients reliable?

The present study was designed to compare the subjective complaints of 50 traumatically brain injured (TBI) patients with the observations of their significant others. The complaints of the TBI patients and their significant others were contrasted according to the severity of the TBI and the type of complaint (physical, cognitive/behavioural and emotional). While no differences were found in physical complaints, the cognitive/behavioural and emotional complaints of TBI patients, regardless of the severity of the initial TBI, were significantly under-reported in comparison to the observations of their significant others. The data suggests that while this finding was most likely due to the TBI patients' poor awareness, it was unlikely to be the result of psychological denial since all of these individuals were evaluated in the context of being a plaintiff in personal injury litigation or a claimant in a Workers' Compensation claim. The data suggests that the cerebral trauma these patients sustained played a major role in their ability to recognize their cognitive, behavioural and emotional symptoms. Finally, the data suggests that clinicians should obtain information about the TBI patients' cognitive/behavioural and emotional functioning from their significant others, rather than rely entirely on the TBI patients' subjective assessment of these problems.
