AI-CONECT: A Conversational AI for Early Dementia Prevention in Socially-Isolated Older Adults (AI-CONECT)
AI-CONECT: A Conversational AI for Early Dementia Prevention in Socially-Isolated Older Adults Based on the Efficacy-Proven I-CONECT Study
연구 개요
상세 설명
Social isolation is a well-established and modifiable risk factor for cognitive decline and dementia. The completed I-CONECT trial (NCT02871921) showed that frequent, one-to-one, semi-structured conversational engagement delivered remotely by trained human interviewers improved cognitive outcomes among socially isolated older adults with mild cognitive impairment. Two limitations have constrained translating that approach into a scalable preventive intervention: its reliance on trained human interviewers limits scalability, and the behavioral mechanisms responsible for its cognitive benefits remain incompletely understood.
AI-CONECT addresses both limitations by delivering the conversational intervention through a conversational artificial intelligence (AI) voice chatbot rather than a human interviewer, and by testing a hypothesized behavioral mechanism: that the intervention increases participants' social self-efficacy (confidence in their ability to engage socially), which in turn increases real-world social engagement.

Social Self-Efficacy
기간: From enrollment to the end of intervention at 8 weeks
|
Participants' self-efficacy on social interactions using an instrument adapted from the Exercise Self-Efficacy Scale (EXSE, by McAuley, 1993).
The scale comprises three items of confidence: interacting with others regularly, engaging with others when feeling less connected, and engaging others in conversations.
The three items are adapted to social interaction in person and using technology (e.g., video calls), respectively.
Each item is rated from 0 (not at all confident) to 10 (completely confident).
A mean score is computed across the six items (range 0-10), with higher scores indicating greater social self-efficacy.
