Measuring perceived communicative ability after traumatic brain injury: reliability and validity of the La Trobe Communication Questionnaire.
OBJECTIVE
Further psychometric evaluation of a measure designed to assess communication ability after traumatic brain injury (TBI).


METHODS
Internal consistency, test-retest reliability, and validity for self-report and close-other versions of the tool were evaluated.


METHODS
Eighty-eight adults with severe TBI (mean posttraumatic amnesia 53.12 days) and 71 close others (relatives or friends).


METHODS
The La Trobe Communication Questionnaire (LCQ), a 30-item questionnaire that measures cognitive-communication ability from multiple perspectives.


RESULTS
Internal consistency coefficients were above 0.9 and test-retest reliability exceeded 0.80. The questionnaire was sensitive to the effect of severity of injury.


CONCLUSIONS
The La Trobe Communication Questionnaire is a promising tool for measuring perceived communication ability in adults with severe TBI.
