ABSTRACT
Background:
Older African American/Black adults are twice as likely to develop Alzheimer's disease and related dementias (ADRD) and have the lowest level of ADRD health literacy compared to any other ethnic group in the U.S. Low health literacy concerning ADRD negatively impacts African American/Black people in accessing adequate healthcare.
Objective:
The present study explores how three technological modalities—voice assistants, chat-bots, and mobile apps—can assist older African American/Black adults in accessing ADRD information to improve ADRD health literacy. More specifically, the focus is on understanding the unique needs of this population concerning the use of digital tools when accessing ADRD-related information.
Methods:
Using the Wizard of Oz usability testing method, we assessed the three modalities with a sample of 15 older African American adults. The 15 participants were asked to interact with the three modalities to achieve different tasks and search for ADRD related health information.
Results:
Our findings revealed that the content presented by the technology should be made fully accessible to this population and should be paired with credible sources. Additionally, the content should be tailored for African American Black communities. The interaction with the tool should be time efficient, and it should foster a sense of control and representation.
Conclusions:
We conclude that when designing ADRD related interventions for African American / Black older adults, it is imperative to shape the content as well as the interaction to be tailored for African American / Black communities' needs and demands.
