Summary

This study tests the feasibility, acceptability, and efficacy of a multimodal intervention (walking, social engagement, and reminiscence), including the use of wearable digital biomarkers, for cognitively healthy and mildly cognitively impaired African Americans aged 65 and older.

Detailed description

Cognitively healthy and mildly cognitively impaired participants engage in up to 8 weeks of baseline data collection and 4-16 weeks of triadic neighborhood walking using a group tablet device to access pre-programmed 1-mile routes. GPS (Global Positioning System)-triggered historical images of local Black culture and history along the route prompt conversational reminiscence about Portland, Oregon's historically Black neighborhoods. Digital biomarker technology (a continuously worn actigraph watch and an unobtrusive under-the-mattress sleep sensor) and weekly online surveys via a study Chromebook assess feasibility, acceptability, efficacy, and health outcomes. Intermittent discussions and check-ins with participants, and observational sessions will be used to elicit participant feedback.
