Aphasia masks the inherent competence of an individual due to disease or impact to areas of the brain responsible for language. An individual may have difficulty with talking, understanding, reading, writing or a combination of these; depending on the location of the lesion, type and severity of aphasia. When an individual's ability to participate in conversation is impaired, every single relationship, life role and activity in his or her life is at risk. Aphasia has the potential to incite isolation and impact mental and physical health, through a reduction in self-identity. Aphasia affects approximately one-third of the stroke population and as such, it has implications for interactions with health professionals (HPs) and important healthcare decisions. Hence, there is scope for healthcare providers to receive education about aphasia and understand it is not just in the remit of speech-language pathology (SLP). Moreover, a SLP's work is not limited to direct language and functional communication therapy for people with aphasia (PWA). Rather, there is a duty of care to advocate for communication access and encourage a holistic, collaborative healthcare service between all consumers and providers. It is therefore important that system changes occur to ensure that communication is seen as an essential activity of daily living, just as the inability to walk up stairs or not manage routine household tasks (e.g. make a cup of tea) are viewed. Communication partner training (CPT) offers a potential solution to minimise communication barriers, facilitate meaningful conversations and promote involvement in everyday activities, including healthcare decisions and salient exchanges with HPs and HP students. In its essence, CPT provides an opportunity to acknowledge and reveal the competence of an individual with aphasia, using techniques identified as being effective in supporting communication exchange. Supported conversation tools provide a vehicle of how to have a conversation without being prescriptive to conversation content. Further, the use of synchronous (real time) telepractice may provide an ideal platform to allow CPT delivery within a dynamic, time-constrained environment. The overall aim of this thesis was to investigate the impact of implementing a CPT program on PWA, HPs and HP students in order to contribute to the evidence base for improving efficiency of communication for people with communication impairments accessing healthcare. One specific aim was to determine whether a synchronous telepractice model could be a feasibly effective method for providing CPT. In order to address the thesis aim, a series of six studies, resulting in eight manuscripts, were conducted.
