Background: People with aphasia are vulnerable recipients of healthcare. The nature of the communicative environment and the communication disability can adversely impact access to timely and quality healthcare. Student healthcare professionals are often underprepared to interact successfully with people with aphasia and may benefit from communication partner training (CPT). Aims: To investigate the potential effectiveness and acceptability of a brief, two-part introductory Supported Conversation for Adults with Aphasia (SCA[superscript TM])-based CPT package, delivered to a sample of students across a diverse range of healthcare disciplines. Methods & Procedures: A pre-post-within group experimental design was used to investigate the potential effectiveness and acceptability of an online CPT package (50 minute module + 1 hour workshop) for healthcare students. The Aphasia Attitudes, Strategies and Knowledge (AASK) survey measured participants' knowledge of aphasia, facilitative communication strategies and attitudes towards people with aphasia. Data were collected pre-training, following the training module and following the workshop, and 6 weeks post-training. Statistical analysis was conducted on the AASK data. In addition, participant feedback (ratings and open text responses) was collected after the workshop. Ratings were analysed descriptively, and thematic content analysis was used for open text responses. Outcomes & Results: 236 participants completed the pre-training AASK and 106 completed the AASK at subsequent time points. Statistically significant gains were demonstrated from pre- to post-module completion. Between the end of the module and the end of the workshop, some gains were maintained and others showed further statistically significantly improvements. While all gains were not maintained at the 6-week follow-up, statistically significantly improvements from pre-training scores remained evident. Student feedback was predominantly positive, with suggested improvements for training content and length. Conclusions & Implications: The results provide preliminary evidence that a brief, online CPT package can support student healthcare professionals' knowledge and attitudes towards aphasia and communicating with people with aphasia. Online training was acceptable to students and feasible as an embedded or optional component of curriculum. Ongoing training (e.g., in the form of refresher sessions) and inclusion of a skills-based component are recommended to maximize communication skill development.
