Alzheimer Caregiver Social Support Trial Published November 12: 966 Participants over 12 Months, 82.3 Percent Completed at Least 9 Months, Isolates Fell 46.2 Percent
New York City, New York — Results of a social media support trial for family caregivers of people with Alzheimer's disease and related dementias were published on November 12 in npj Mental Health Research. The NIH Stage II and III clinical trial enrolled 966 participants.
African American and Hispanic family caregivers aged 18 and older received daily social support messages for 12 months. The primary outcomes were an emotional valence score quantified using natural language processing, and the proportion of isolated participants continuously captured on the platform.
Retention was high, with 82.3 percent of participants completing at least 9 months despite 86.7 percent of the cohort having low digital literacy. Both groups showed significant improvements in emotional valence scores, at p less than 0.001, with a Cohen d of 0.756, and the number of isolates fell by 46.2 percent, with a Cohen h of 1.144.
