PROJECT SUMMARY One in nine people aged 65 or older in the US lives with Alzheimer's disease (AD) or Alzheimer's disease-related dementia (ADRD). Patients living with dementia (PLWD) and their care partners rely on primary care clinic visits for dementia information, management, and community referrals. Quality interpersonal communication is associated with improved health-related outcomes. Models of triadic interactions purport that information exchange, rapport, and patient and care partner engagement in goal setting and decision-making are key to effective interpersonal communication. However, the degree to which effective interpersonal communication is achieved during triadic visits is unknown, and few interventions to support it exist. Using audio recordings of clinic visits is a novel, evidence-based strategy with the potential to support triadic interactions, yet its application is unexplored in dementia. The objective of this proposal is to design an intervention that enhances interpersonal communication in triadic visits using visit recordings. Applicants will follow the NIH Stage Model to redesign their visit recording platform, HealthPAL, which leverages natural language processing to structure visit information. The specific aims are: Aim 1 (Stage 0): Conduct a prospective observational study, with outpatient clinic visits of 200 triads (PLWD/care partner/clinician) audio recorded for 12 months; 1.a. Examine the association between interpersonal communication in triadic AD/ADRD visits and health-related outcomes; 1.b. Identify barriers and enablers to interpersonal communication in triadic AD/ADRD visits; Aim 2 (Stage 1A): Adapt HealthPAL to enhance interpersonal communication in triadic AD/ADRD visits; and Aim 3 (Stage 1B): Demonstrate the usability, feasibility, acceptability, and potential effectiveness of HealthPAL in AD/ADRD. Applicants hypothesize: 1) Constructs from models of interpersonal communication will be associated with health-related outco
