Systematic Review of Training Communication Partners of Chinese-speaking Persons With Aphasia

Abstract

ObjectiveTo determine the aims, participants, and outcomes of training communication partners of Chinese-speaking persons with aphasia (PWA). Data SourcesSixty search terms related to communication partner training (CPT) in Chinese characters were searched in 8 electronic databases (published 1991-2020). Study SelectionJournal articles written in Chinese that primarily target the Chinese audience and university theses were selected for review. Studies involving CPT and training to enable communication partner to deliver language tasks were included, but reports without PWA or direct training of communication partners were excluded. A final corpus of 37 articles, representing publications of group studies, case studies, qualitative studies, and opinion articles, were selected for full review. Data ExtractionFor all articles, 2 reviewers independently reviewed abstracts, excluding those without PWA or those that did not involve training of communication partners. One reviewer extracted descriptive data of participants with aphasia, communication partners, intervention details of the intervention (purpose, amount, setting, description), outcome measures, results, and clinical guidelines. A second reviewer performed accuracy verifications. Data SynthesisQuality of reviewed articles were classified using the American Academy of Neurology levels of evidence. The current review suggested an evidence base of low to medium quality supporting 2 intervention groups: (1) training partners to deliver therapy tasks and (2) training to improve communication between PWA and their communication partners. There was a higher proportion of persons with acute and subacute aphasia involved in these investigations, suggesting evidence on treatment efficacy of CPT in the acute stage. ConclusionsAdditional high-quality research with a better methodological quality, for example, randomized controlled trials or experimental design, are required to strengthen the current evidence of CPT. This systematic review suggests that the inclusion of studies published in languages other than English may influence the findings of mainstream reviews relating to aphasia.
