title: Awareness of behavioral, cognitive, and physical deficits in acute traumatic brain injury.
abstract: OBJECTIVE
  To compare awareness of deficit in 3 domains of function (physical, cognitive, behavioral/emotional) in acute traumatic brain injury (TBI), controlling for severity of impairment in the different domains.
  
  
  METHODS
  Inception cohort.
  
  
  METHODS
  Three inpatient rehabilitation programs.
  
  
  METHODS
  People with acute TBI (N=161), tested as soon as feasible after posttraumatic amnesia.
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  Awareness Questionnaire (AQ) completed by the person with TBI and the treating neuropsychologist; and self- and clinician-rating scores calculated in the 3 domains.
  
  
  RESULTS
  For participants who were rated by clinicians as more impaired in at least 1 domain (ie, scored lower on the AQ), self-ratings differed significantly from one another in all 3 domains, with behavioral self-ratings highest, physical self-ratings lowest, and cognitive self-ratings intermediate. In subgroups of participants rated at the same level by clinicians in all 3 domains, physical self-ratings were also lowest, that is, more consonant with clinician ratings. Participants tended to rate themselves as relatively unchanged in cognitive and behavioral domains regardless of the level of clinician ratings on these factors.
  
  
  CONCLUSIONS
  Patterns of discrepant awareness of deficit in different functional areas seen in postacute TBI also appear to be present acutely and are not entirely related to differential severity of deficit. We discuss several possible reasons for discrepant awareness of deficit, including differences in internal and external feedback, cultural and psychologic factors, and different levels of ambiguity inherent in causal explanations for different types of problems.
