Study Details

Brief summary:

The goal for this project is to support the cognitive components of older adults' health-management activities through development of digital assistant technology tools tailored to three exemplar healthcare management task activities: accessing support services, managing healthcare finances, and using the health-management tools provided by Medicare.gov. This project will leverage the machine-intelligence expertise of our collaborators and our experience in developing and evaluating technologies for supporting the health and wellbeing needs of older adults to harness technology to provide cognitive support to aging adults, including those with Mild Cognitive Impairment (MCI) and lower SES.

Interventions and Outcome Measures

Arms

experimental: Sidekick Condition

Participants will be given a brief introduction to Large Language Models, how they can be used to solve queries, and introduced to Sidekick. Some simple example queries will be used to demonstrate its use, how to construct prompts, and to illustrate the nature of Sidekick's responses. Participants will also be instructed about different degrees of specificity of information and other customization features of Sidekick and how to use responses as a springboard for iterative prompting (sequential queries).

active comparator: Usual-Tool Control Condition

Participants will be asked to open the medicare.gov website. They will be shown the basic structure of the homepage and the distinctions between tabs on the website. Examples of information that can be obtained from these different tabs will be demonstrated. Navigation between different parts of the website will also be demonstrated.

Interventions

Project 3, Phase 2: Clinical Trial

A digital support tool (adapted for this study for Medicare) with a diverse sample of adults age 60+ with and without a cognitive impairment.

Primary outcome measure

  • Project 3, Phase 2: Mean Perceived System Usefulness [ Time Frame: Immediately following completion of the task performance session ]
  • Project 3, Phase 2: Sum of Performance Accuracy [ Time Frame: Immediately following completion of the task performance session ]
