Study 1: Social Engage Coaching R61 Phase

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.
