Impact of Covid-19 on Frequent Social Interaction Through Communication Technologies in the Cognitive Status of Socially-isolated Older Adults
The current study will examine the impact of frequent social interaction through communication technologies during COVID-19 pandemic in the cognitive status of socially-isolated older adults with and without cognitive impairment. Patients will take place in an experimental crossover study, participants will complete one month of an intervention and one month of as passive control. The goal of this study is to determine: A.) if frequent social interaction through ICT during COVID-19 pandemic will have a significant positive impact in cognitive performance on testing, and B.) how social isolation and cognitive status influence misconceptions around the current pandemic.

- Study Type
- Intervention Model
- Crossover Assignment
- Intervention Model Description
- The investigators will employ an AB/BA crossover design (2-sequence, 2-period, 2-treatment design) where A will be the intervention phase and B will be the passive control phase. Each period will have a duration of 1 month. Assessment of the primary outcome will be done at the end of each period. Since this is a study of a behavioral intervention, 4-week washout period will suffice to observe an acute change in cognitive performance without significant carryover effects. To avoid imbalance among groups, randomization will be stratified by cognitive syndrome diagnosis (healthy older adult, mild cognitive impairment and mild dementia). Participants will be randomized to the treatment sequences using a 1:1 allocation ratio.
- Primary Purpose
- Single (Outcomes Assessor)
- Masking Description
- Trial investigators and outcome assessors will be blind to the treatment randomization and allocation..
Group A Intervention
|Participants in Group A will receive an intervention designed to provide participants with more social interaction during a time of social distancing and highly limited in-person social interactions||
Group B Control
|Participants in Group B will not receive any new interventions.||
- Enrolling by invitation
- Boston University
The current study will examine the impact of frequent social interaction through communication technologies during COVID-19 pandemic in the cognitive status of socially-isolated older adults with and without cognitive impairment. An estimated 150 total participants will be recruited over the course of 1 year: 50 healthy older participants, 50 patients with amnestic mild cognitive impairment, and 50 patients with mild AD.
This study employs an AB/BA crossover design (2-sequence, 2-period, 2-treatment design) where A will be the intervention phase and B will be the passive control phase. Each period will occur over a duration of 1 month. Participants will either receive an intervention designed to provide participants with more social interaction during a time of social distancing and highly limited in-person social interactions (Intervention Group) or will not receive the intervention (Control Group). The investigators will conduct pre- and post- neuropsychological testing to assess changes in cognitive status (e.g., memory, language, executive functioning) in the intervention group after each intervention phase. Neuropsychological tests assessing changes to cognition will be completed prior to participant assignment to the Intervention or Control Group. Following this assessment, the first phase of the intervention will begin, and the initial intervention group (Group A) will receive the intervention, and the other group (Group B) will act as a control group. After the intervention phase has ended, both groups will be assessed again using neuropsychological tests. Following the re-assessment, Group B will receive the intervention, and Group A will act as a control. After the second intervention phase has ended, both groups will be assessed once more using neuropsychological tests.
