Details and patient eligibility

About

The study aims to randomize 320 (160 Caucasian, 160 African American) socially isolated adults 75+ years old (50:50 split between those with normal cognition and mild cognitive impairment (MCI)) recruited from the community to either the Video Chat Group or the Control Group. The participants in the Video Chat Group will receive a computer and internet service for the duration of the study, which they will use to video chat with study staff for 30 minutes/day 4x/week for 6 months (high dose), and then 2x/week for an additional 6 months (maintenance dose). The efficacy examination of the maintenance dose is limited to an exploratory aim. Both intervention and control groups will have a brief (about 10 minutes) telephone check-in with study staff once per week. In-home testing will occur at Baseline and 6 months. A sub-sample of participants** will be assessed at 12 months (exploratory) after additional 6 months of maintenance dose. All participants at OHSU will have their medication compliance tracked using an electronic medication monitoring device and participants at both OHSU and UM will have MRIs at Baseline and 6 months, if they are able to safely receive MRIs. Participants at both sites will contribute saliva for genetic testing (optional consent), and all video chat and neuropsychological assessment sessions will be recorded for speech and language analysis (consent required for participation).

Full description

**Due to COVID-19 pandemic and resultant research hiatus and the subsequent changes in assessment modality from in-person to telephone (T-COG) assessments, M12 (Months 12) assessments are conducted only among those who completed M12 assessments before March, 18, 2020.

Conversational Engagement
Experimental group
Description:
Participants engage in 30-minute face-to-face communications with study staff through internet/webcam 4 times per week for 24 weeks (6 months). Under an exploratory aim, a limited number of participants will be further followed by sustaining dose of 2 times per week of 30 minutes session for additional 24 weeks (6 months). Conversational staff will facilitate content-standardized but naturalistic-style social engagement. Staff and participants will engage in conversation about a wide variety of topics that are culturally and personally relevant and interesting to participants. Each day, participants will be able to choose from topic options. Participants will also receive a phone call once per week that lasts approximately 10 minutes; interviewers ask brief questions to monitor participant social activities and health conditions.
