The team repeats the baseline test for all participants. We will measure the changes for-

• Sedentary behavior
• Physical functions
• Geriatric physical performance

using a self-report survey, a lab-based assessment, and an individual interview.

Comparing the changes in health outcomes using hypothesis testing and advanced machine learning modeling, the team will quantify the complex human behaviors induced by enhanced technological and conventional behavioral strategies. The team also will use qualitative assessments from interviews to evaluate the overall experience with the app (e.g., feasibility, usability) and the perceived effectiveness of the developed strategies to understand human-technology interactions for older adults.  Data will be collected either over the phone or in-person, depending on their preference/ CDC guidelines during the pandemic.
