虚拟生活俱乐部的干预，以改善社区居民的孤独和冷漠 (LSC Feasible)

Virtual Group Reminiscence Therapy

Virtual group reminiscence therapy will be provided by the Life Story Club©. Participants will meet virtually via Zoom© with their group (6-10 people) weekly for one hour over a 12-week period to exchange life stories and share in conversation. Groups will be conducted in entirely in English or Spanish, based on participant preference. Each week, the LSC© facilitator will guide the group with question prompts to encourage participants to share personal information, build friendships & rapport, and create a sense of community. LSC© facilitators are trained in group interview techniques, technology management, and know how to respond appropriately to sensitive information that may emerge during group exchanges.

Loneliness will be assessed using the University of California, Los Angeles (UCLA) Loneliness Scale questionnaire. The UCLA Loneliness Scale is a 20-item measure that assesses how often a person feels disconnected from others. Participants provide responses using a 4-point Likert scale where 1 = never; 2 = rarely; 3 = sometimes; 4 = always, for an overall possible scoring range of 20-80, such that higher scores are associated with increased loneliness. Positively worded items in the questionnaire must be reverse-coded before reporting. For purposes of this study changes from baseline to 3 months and baseline to 6 months will be assessed whereby positive values are indicative of an increase in loneliness from baseline and negative values a decrease in loneliness from baseline. Group scores will be summarized using basic descriptive statistics.

Apathy will be assessed using the self-reported Apathy Evaluation Scale (AES-S). The AES-S is an 18-item questionnaire that addresses characteristics of goal directed behavior that reflects apathy including behavioral, cognitive, and emotional indicators. Participants provide responses based on a 4-point Likert scale where 1 = not at all true; 2 = slightly true; 3 = somewhat true; and 4 = very true, for an overall possible scoring range of 18-72, such that higher scores are associated with greater apathy. Positively worded items in the scale must be reverse-coded before reporting. For purposes of this study changes from baseline to 3 months and baseline to 6 months will be assessed whereby positive values are indicative of increased apathy from baseline and negative values decreased apathy from baseline. Group scores will be summarized using basic descriptive statistics.

Cognition will be assessed using a version of the Telephone-Montreal Cognitive Assessment (T-MoCA). The T-MoCA is a 22-item phone-administered exam which assesses a range of global cognitive domains including attention, memory, language, and orientation. Each item is one point yielding an overall possible scoring range of 0-22, with higher scores being indicative of better cognitive function. Scores of 18 or below are generally suggestive of Mild Cognitive Impairment (MCI). For purposes of this study changes from baseline to 3 months and baseline to 6 months will be assessed whereby positive values are indicative of increased cognition from baseline and negative values decreased cognition from baseline. Group scores will be summarized using basic descriptive statistics. To reduce practice effect Version (V)8.1 will be administered at baseline, V8.2 at 3 months, and V8.3 at 6 months. Scoring ranges are identical for all 3 versions.

Meaning and purpose will be assessed as a composite measure using the Patient-Reported Outcomes Measurement Information System (PROMIS) Meaning and Purpose 4-item scale. The 4-item scale is designed to assess an individual's subjective experience of meaning and purpose in life. Participants provide responses on a 5-point Likert scale ranging from 1-5 for an overall possible scoring range of 4-20, such that higher scores are associated with greater meaning and purpose. For purposes of this study changes from baseline to 3 months and baseline to 6 months will be assessed whereby positive values are indicative of increased experiences of meaning and purpose from baseline and negative values decreased experiences of meaning and purpose from baseline. Group results will be summarized using basic descriptive statistics

Depressive symptoms will be assessed by administration of the Geriatric Depression Scale - Short Form (GDS-15), The GDS-15 is a 15-item questionnaire in which participants provide a dichotomous (Yes/No) response as to how they have felt over the prior week. Answers suggestive of depression are bolded/italicized on the questionnaire (may either be 'Yes' or 'No' depending on the item). A score of 1 point is assigned for each bolded/italicized response such that higher scores are associated with more depressive symptoms. A score of 0 to 5 is normal. A score greater than 5 suggests depression. For purposes of this study changes from baseline to 3 months and baseline to 6 months will be assessed whereby positive values are indicative of increase in depressive symptoms from baseline and negative values a decrease in depressive symptoms from baseline. Results will be summarized using basic descriptive statistics.

Social Support will be assessed using the Medical Outcomes Study (MOS) Social Support Scale. The MOS is a 19-item multidimensional, self-administered instrument that measures the availability of support, if needed. The overall social support component of the MOS Social Support scale will be used. Participants provide responses on a 5-point Likert scale ranging from 1-5 for an overall possible scoring range of 19-95, such that higher scores are associated with greater availability of social support. For purposes of this study changes from baseline to 3 months and baseline to 6 months will be assessed whereby positive values are indicative of increased social support and purpose from baseline and negative values decreased social support from baseline. Group results will be summarized using basic descriptive statistics
