Conceptual and methodological challenges in discourse assessment with TBI speakers: towards an understanding.
The primary objective of this paper is to review theoretical and methodological literature pertaining to the clinical evaluation of discourse abilities in speakers who have sustained traumatic brain injury (TBI). A brief history of the study of discourse impairment in this population is followed by consideration of the following issues: (1) sampling (genres selected, the physical setting in which sampling takes place, the relationship between speakers, elicitation techniques, presence of recording devices, the number of samples required, and transcription); (2) measurement; (3) the relationship between sampling and measurement; (4) other approaches to discourse assessment (self and close other report); (5) consideration of the criterion of 'normal' which clinicians should employ; (6) the relationship between discourse impairment and measures of executive function; and (7) the relationship between discourse impairment and seventy of injury. Recommendations arising from a critical review of these domains are made for both clinical practice and research.
