Using conversation analysis to assess and treat people with aphasia

This article gives an overview of the application to aphasia of conversation analysis (CA), a qualitative methodology for the analysis of recorded, naturally occurring talk produced in everyday human interaction. CA, like pragmatics, considers language use in context, but it differs from other analytical frameworks because the clinician is not making interpretations about how an aspect of language should be coded or judging whether an utterance is successful or adequate in terms of communication. We first outline the CA methodology before discussing its application to the assessment of aphasia, principally through the use of two published assessment tools. We then move on to illustrate applications of CA in the field of aphasia therapy by discussing two single case study interventions. Key conversation behaviors are illustrated with transcripts from interactions recorded by the person with aphasia and the person's habitual conversation partner in the home environment. Finally, we explore the implications of using CA as a tool for assessment and treatment in aphasia.
