Interaction-focused intervention for acquired language disorders: Facilitating mutual adaptation in couples where one partner has aphasia

This paper discusses the implementation and evaluation of an interaction-focused intervention single case study for a couple where one partner has aphasia. Drawing on conversation analytic research, naturally occurring conversations of the couple at home pre- and post-intervention were collected and analysed. Analysis of the speaker with aphasia's topic initiating turns in the pre-intervention conversation showed that in each case a feature of the attempt was that the speaker had difficulty in getting the topic initiation accepted and established. Drawing on conversation analytic work on topic initiations in normal conversation, intervention focused on training the couple to co-produce these topic initiating turns of the speaker with aphasia in a collaborative and step-by-step manner. Post-intervention, there was evidence that the couple were now using this new method, albeit in a slightly different way to that worked on in the intervention sessions. Drawing on work into adaptation by speakers with aphasia and their conversation partners, these results are discussed in terms of a process of mutual adaptation by the couple. © 2011 The Speech Pathology Association of Australia Limited
