CAYA, Revised December 2017– Tessa Lowis, Michelle Bunney, Tiffany Visser, Tara Commandeur, Monica Francella

This document is based on the AAC Aphasia Category framework by Garrett and Lasker (2005). The framework differentiates between two types of communicators with Aphasia: 1. Independent communicators: individuals who are able to independently initiate use of different communication strategies. 2. Partner Dependent communicators: Individuals who consistently depend on a partner to manage informational demands and provide communication choices within highly familiar contexts. These five assessment questions help us determine which category best describes the client: 1. Does the person with Aphasia (PWA) use unaided communication strategies (e.g., gestures, writing drawing)? If so, with what degree of cueing? 2. Are partner dependent strategies being used? (e.g. partner writing key words, providing choice of responses)

3. Can the PWA use external stored information/messages on a communication board? The Multi-Modal Communication Screening Task for Persons with Aphasia (MCST-A) can be used to assess this skill. Free download: https://cehs.unl.edu/documents/secd/aac/assessment/picture.pdf (stimulus book), and https://cehs.unl.edu/documents/secd/aac/assessment/score.pdf (score form)

4. Can the PWA access stored messages on a speech generating device? ‘Aphasia -Stored Message Assessment’ pages available in TouchChat through iShare: Go to Public Files > Adult > General Communication > Aphasia-Stored Message Assessment. 5. Can the PWA formulate/generate messages to communicate? These questions may be answered by observing the PWA and a partner in role play situations. Refer to the checklist below to determine which category best matches your client. Use the page for the specific category to guide your assessment and treatment. Consider using Talking Mats to assist with AAC system development (E.g. topic selection). Visit www.talkingmats.com for more information.
