The purpose of this study is to test whether an individual coaching program called Social Engage Coaching (or 'Engage Coaching' for short) helps adults age 60 and older feel more connected to other people in ways that matter to them. Procedures include participating in a Social Engage Coaching program, research assessments with surveys, and assessments completed on a cell phone. Engage Coaching involves individual sessions with a trained Engage Coach (up to 10 sessions) that are designed to help participants improve social relationships and well-being. All subjects will receive the scheduled baseline and follow-up interviews by the research team. These interviews will be conducted at study start, mid-way through the program at 8 weeks and after completing the program at 16 weeks. Interviews will be via Zoom/phone as well as surveys done online.

The R61 phase is a single-arm trial of S-ENG plus eCAU (n=30) with 1 week of smartphone-based target assessment at baseline, 8-weeks and 16-weeks. Participants are 30 adults age 60 and older who report clinically significant loneliness and suicide ideation and reside in a senior living community (SLC). We will use ambulatory assessment via smartphones, including both active self-report (ecological momentary assessment, EMA) and passive sensing (audio recordings & GPS) to comprehensively assess indices of social connection. Subjects will complete EMA recordings using a smartphone daily following 3 personally-selected times for prompts (to enhance recall and ease of completion of assessments) for 10-days prior to starting study interventions, beginning the day after the baseline visit. Each EMA instance takes approximately 2-5 minutes to complete. EMA will be integrated with other smartphone technology to passively capture social behavior. The Electronically Activated Recorder (EAR) will passively measure social behavior (i.e., conversation frequency, duration, and valence). GPS- will track time outside the home. Subjects will be given a study smartphone designed for older adults to use during assessment periods. All subjects who successfully complete the smartphone assessment protocol at baseline will be assigned to S-ENG. S-ENG involves 10 individual coaching sessions over (up to) 4 months. S-ENG is a stepped, modular intervention that addresses barriers to action plan implementation and challenges in processing positive outcomes when exposed to socially rewarding activities. Psychoeducational materials address the importance of social connection. Subjects complete a values clarification exercise on aspects of connection most important to participants to inform personalized activities most likely to impact loneliness. Coaches are instructed to focus action plans on activities that foster social connection. The follow-up assessments at 8- and 16-weeks include baseline measures and smartphone measures.

Inclusion criteria are adults age 60 or older who live in senior living communities, endorse clinically-significant loneliness and suicide ideation over the prior month. Exclusion criteria are current problem drinking, psychosis, significant cognitive impairment, and hearing problems that preclude engagement with S-ENG and research assessors.

This study will use the NIMH Data Archive (NDA) system and procedures for its Data Sharing Plan. The NDA is a secure informatics platform for scientific collaboration and data-sharing that enables the effective communication of detailed research results, tools, and supporting documentation. Investigators will deposit all raw and analyzed data from experiments involving human subjects into this infrastructure. All data will be de-identified and will be collected from subjects who have broadly consented to share their data for research use or who have consented to share their data for research, with data use limitations.

Subject-level data (individual and derived variables) will be submitted annually using standard NDA data submission deadlines of July 15th each year. Subject-level data will be submitted in the data submission cycle following data collection (for individual variables) or data generation (for derived variables). The first data submission date will be the second cycle after the grant is awarded.

Access to data for research purposes will be provided through an NDA Data Access Committee (DAC). Investigators and institutions seeking data from NDA will be expected to meet data security measures and will be asked to submit a Data Use Certification, which is cosigned by the investigator and the designated Institutional Official(s) at the NIH-recognized sponsoring institution with a current Federal Wide Assurance (FWA).
