Design outcomes

Primary

Measure	Time frame
Verbal fluency test *Evaluation Pre, post-intervention, and once a year during the intervention	—

Secondary

Measure	Time frame
Interpersonal Reactivity Index Social Comparison Orientation scale Zimbardo Time Perspective Inventory Personal Values Questionnaire II Lubben Social Network Scale Kihon Checklist World Health Organization-Five Well-Being Index UCLA Loneliness Scale NEO Five-Factor Inventory WMS-R Logical Memory I and II Mini-Mental State Examination Montreal Cognitive Assessment National Center for Geriatrics and Gerontology-Functional Assessment Tool Blood biomarkers *Evaluation Pre, post-intervention, and once a year during the intervention (For PVQ-II and MMSE, only at pre- and post-intervention. Due to scheduling constraints, NEO-FFI will be measured at two time points during the intervention period, preferably as close as possible to the baseline and endpoint. For blood biomarkers, measurements will be taken at a time point during the intervention period as close as possible to baseline, annually during the intervention, and after the intervention.) As implementation outcomes, dropout rate (acceptability) and the number of questions asked per conversation session (adherence) are recorded.	—
