Background: The provision of aphasia-friendly environments is important for reducing the disability experienced by people with aphasia. However, the term aphasia-friendly environment has yet to be explicitly defined in the literature. Aims. This review defines aphasia-friendly environments, critically evaluates the relevant literature. and highlights the gaps in research in this area. Main Contribution: The World Health Organisation's (WHO) International Classification of Functioning, Disability and Health (ICF) (WHO, 2001) is Used as a framework for identifying the specific barriers and facilitators that need to be considered when creating an aphasia-friendly environment. Research focusing on Multiple ICF environmental factor domains is presented, followed by a review Of Studies that focus on specific environmental factor domains. Conclusions. More research identifying the range of environmental factors that may be important to consider when creating aphasia-friendly environments is required. In addition, further rigorous studies focusing on specific ICF environmental factor domains are needed.
