OBJECTIVE: Further psychometric evaluation of a measure designed to assess communication ability after traumatic brain injury (TBI). DESIGN: Internal consistency, test-retest reliability, and validity for self-report and close-other versions of the tool were evaluated. PARTICIPANTS: Eighty-eight adults with severe TBI (mean posttraumatic amnesia 53.12 days) and 71 close others (relatives or friends). MEASURE: 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. CONCLUSION: The La Trobe Communication Questionnaire is a promising tool for measuring perceived communication ability in adults with severe TBI.
