Given the rich, complex communication experiences provided in these groups, it seemed plausible that participation in them could result in improvement of simpler aspects of discourse production. To examine the effects of group communication treatment on the informativeness and efficiency of structured and conversational discourse tasks in adults with chronic aphasia. The data for this study were discourses elicited prospectively from 23 adults with chronic aphasia by Elman & Bernstein-Ellis (1999a) as part of their randomised controlled trial, but never previously transcribed or analyzed. We evaluated changes in discourse informativeness and efficiency at treatment exit and follow-up with Bayesian generalised linear mixed-effects models. Individual effect sizes at exit and follow-up were estimated and a region-of-practical-equivalence approach was used to evaluate whether the posterior distributions at each timepoint for each participant were clinically meaningful. Results at the group level revealed that structured discourses became more informative and efficient after treatment, and that this improvement was at least maintained at follow-up. Informativeness of conversational discourse did not change from treatment entry to exit, but there was modest evidence of improvement at follow-up. There was no evidence of change to the efficiency of conversational discourse at either timepoint. There was wide variability in individual response to the treatment. Participation in conversation-based communication group treatment was associated with more informative and efficient structured discourse production and modestly improved informativeness in conversational discourse. Examining individual responses to treatment provided additional insight about the group-level outcomes and provided some clues about factors that might have influenced performance for some of the participants. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
