Communication Strategies to Support Decision-Making by Persons with Aphasia: A Scoping Review

Background: An individual's ability to make autonomous decisions is fundamental to self-determination. The presence of neurological pathology, for example, aphasia, and its associated difficulties with language and/or cognition, may affect an individual's capacity to make decisions, or their ability to reveal their capacity to make decisions. Decision-making by persons with aphasia (PWA) can be enhanced when communication partners are trained and if communication supports are provided, for example, supports that reduce the linguistic and cognitive demands of the task, and/or that facilitate expression. Aims: The main aim of this review is to identify the types of decisions for which persons with post-stroke aphasia receive support, the communication partners involved in supporting decision-making by PWA and the communication strategies implemented to support decision-making by PWA. Methods & Procedures: A multifaceted search strategy was used. Specific keywords were used to search seven electronic databases. Hand-searches of two journals, as well as ancestral searches of the reference lists of selected articles was also performed. Through the application of predefined selection criteria, 16 journal articles, spanning from 1998 to 2021, were selected from the initial yield of 955 articles for inclusion in this review. Data pertaining to the aims of the study were extracted using a data-extraction form. Outcomes & Results: This review shows that most of the research to date has focused on supporting persons with post-stroke aphasia in decisions pertaining to discharge planning or accommodation, and decisions pertaining to informed consent for participation in research. The communication partners cited most frequently as supporting decision-making by PWA are speech-language pathologists and family members. A range of communication strategies, most of which are components of Supported Conversation Techniques for Adults with Aphasia (SCA™), support decision-making by PWA. The most frequently listed strategies include augmenting information with different modalities, acknowledging the competence of the PWA, thereby inviting initiation and collaboration by the PWA, and the allocation of sufficient time for the decision-making process. Conclusions & Implications: This review presents research trends regarding the support of PWA in decision-making. Future research should focus on the effectiveness of the different strategies identified, and on the support of PWA in the making of a greater variety of complex decisions.
