The goal of this observational study is to evaluate the reliability, usability, and feasibility of the MEVA Cognitive Wellness Platform in community-dwelling adults aged 55 to 75.
The main questions it aims to answer are:
How consistent is the MEVA Global Cognitive Index when participants complete the MEVA activities again approximately 14 days later? How usable and acceptable is the MEVA platform for older adults in community settings? What completion rates, data quality patterns, and participant feedback are observed during use of the platform?
Participants will:
Complete a baseline study visit lasting approximately 45 to 60 minutes Complete a 7-activity digital cognitive wellness battery Answer questionnaires about usability, technology acceptance, and wellness experience Complete the Saint Louis University Mental Status (SLUMS) examination as an exploratory comparison measure If selected for the retest group, return approximately 14 days later to complete the MEVA activities again
