Participant Flow

Recruitment was conducted between July 2018 and December 2020 from Portland, Oregon, and Detroit, Michigan; Potential subjects were identified via publicly available data; word-of-mouth referrals, and registries.

2 arms were pre-assigned: Conversational Engagement vs Control Group; and were later analyzed by Cognitive Status (Normal Cognition vs MCI).

Measure
Conversational Engagement (MCI)
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. Conversational Engagement: Examine whether increasing social interaction through face-to-face (video chat) conversations could improve cognitive function and whether the efficacy is mediated by improved psychological well-being, targeting older adults aged 75 and older who are socially isolated
Control Group (MCI)
Participants receive a phone call once per week that lasts approximately 10 minutes; interviewers ask brief questions to monitor participants' social activities and health conditions

PRIMARY outcome

Timeframe: Change from baseline to month 6

Population: The pre-pandemic cohort consists of participants who received in-person assessments both at baseline and M6 assessments using the MoCA full battery. During the COVID-19 pandemic, telephone MoCA was used. In the pre-and post-pandemic combined cohort, missing items in telephone MoCA were imputed using available test items. The final report shows model-based analysis results that controlled for confounders.

Global cognitive function measured by the Montreal Cognitive Assessment total score (MoCA total score). Montreal Cognitive Assessment is a neuropsychological test. Total score ranges from 0 to 30. Higher scores indicate better cognitive function.

Cognitive function in language-based executive function measured by Verbal Fluency Animal test. Verbal fluency Animals test is a neuropsychological test. In the test, participants have to produce as many words as possible from a category of animals within 60 seconds. Total score ranges from 0 to 70. Higher scores indicate better cognitive function.
