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.

측정값 설명
기간
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.

기간
Exploratory outcome: Social isolation score
기간: From baseline to week 8

Changes in Lubben's social isolation score (6-item version) from baseline to Week 8.

The 6-item Lubben Social Network Scale (LSNS-6) is a brief measure of social isolation/social network size and support, particularly in older adults. It includes three questions about family ties and three about friendships, assessing the number of people the individual has contact with, feels close to, and can call on for help.

Each item is scored from 0 to 5, giving a total score of 0-30. Higher scores indicate stronger social networks and less social isolation.
From baseline to week 8
Exploratory outcome: Changes in the 3-item UCLA Loneliness Scale (UCLA-3)
기간: From baseline to week 8
The 3-item UCLA Loneliness Scale (UCLA-3) is a brief measure of perceived loneliness and social disconnection. It asks how often a person feels a lack of companionship, left out, and isolated from others. Each item is scored from 1 (hardly ever) to 3 (often). The total score ranges from 3 to 9, with higher scores indicating greater loneliness.

IPD 계획 설명

De-identified transcriptions and other collected data may be shared with external researchers under a Data Use Agreement (DUA). Shareable data may include outcome scores, adherence rates, chatbot-usage metrics, full conversational transcripts (after removal of any incidentally disclosed identifiable information), and audio recordings of sessions. Because raw audio recordings may be inherently identifiable, they will be shared only under a DUA. These data may also be made available to the NIH/NIA Program Official upon request. Data are stored on HIPAA-compliant servers (e.g., MGB Business Dropbox and MGB Azure) and encrypted drives. The participant linkage key is kept within Mass General Brigham. No individual-level data are deposited in public or controlled-access repositories under the current protocol; future repository sharing would require additional IRB review and approval.

IPD 공유 기간

De-identified data and related materials are available upon request; the current protocol does not specify a fixed availability start or end date. Availability and retention follow Mass General Brigham and NIH record-retention requirements.

IPD 공유 액세스 기준

Requests are reviewed by the study team. Sharing occurs only under an executed Data Use Agreement (DUA) or equivalent research agreement approved by the Mass General Brigham Contracting Office, is limited to de-identified (except audio recording as described above) or aggregated data for the analyses described in the protocol, and contractually prohibits re-identification and onward sharing. Data are transferred only via Mass General Brigham-approved secure, encrypted methods.
