Objective: Measure the reliability of a usability assessment tool for assistive augmentative communication technologies. Methods: Twenty-four participants were selected, 12 patients with Amyotrophic Lateral Sclerosis for the Disease Group and 12 without disease and without limitation in the upper limbs for the Control Group. Participants underwent a usability test with an intelligent multifunction keyboard where they had to receive, install, program and perform a task assigned with the technology. In the end, the Augmentative Communication Assistive Technology Usability Assessment Scale was applied to participants where they based their responses on technology experience. The scale consists of general domains and one specific domain for augmentative communication technology. Each domain has items with scores ranging from 0 to 3 of the Likert type, where 0 represents negativity and / or absence of something and 3 positivity and / or presence of something. Data obtained by the scale were tabulated and analyzed using the SPSS version 24 software to calculate reliability according to Cronbach's alpha. Results: The constructed scale presented an acceptable general reliability of α 0.514 and α 0.657 for the specific domain. The technology was evaluated equally as “regular” by both groups, with no statistically significant difference between the mean scale scores between them, with p of 0.94. Conclusions: The developed scale proved to be a reliable instrument, easy to be applied, and with good interpretation by the user, whether he or she has a limiting disease or not. It serves as an important tool both for the end user of the technology, which can identify whether it has good usability, as well as for the company that makes it, avoiding unnecessary expenses and promoting good acceptance by the customer and buyers of the technology, and also for the user. professional who will be able to select the best assistive technology for his patient, avoiding abandonment and dissatisfaction with bad usability technologies.
