March 23, 2026 updated by: Kimberly Van Orden, University of Rochester

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The R33 phase is an RCT (S-ENG+eCAU vs. eCAU only; n=120) with follow-up at 8- and 16 weeks to test target engagement and clinical impact. 10 days of ecological momentary assessment (EMA) will be completed at all assessment points. Participants are 120 adults age 60 and older who report clinically significant loneliness and have access to social activities outside the home. EMA will comprehensively assess indices of social connection. Subjects will complete EMA 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. Subjects who successfully complete the smartphone assessment protocol at baseline will be randomly assigned to coaching or waitlist control. Study conditions are Engage Coaching (10 individual coaching sessions) over (up to) 4 month or waitlist control (assessments only for 4 months and then coaching is offered). The follow-up assessments include baseline measures and EMA.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion criteria:

  • Age 60 or older
  • Access to social activities outside the home, including through living in senior living communities
  • Clinically-significant loneliness over the prior month.

Exclusion criteria:

  • Current problem drinking

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Engage Coaching
Behavioral: Social Engage Coaching (S-ENG)
Social Engage Coaching (S-ENG) involves 10 individual coaching sessions focused on increasing social connection. S-ENG is a stepped, modular intervention that was developed to allow personalization to a given subject's needs, preferences, and individualized barriers to social connection. Early sessions include psychoeducation on the importance of social connection; a values clarification exercise on aspects of connection most important to subjects; and assessment of current social networks and social activities. Together, the coach and subject create a conceptualization of reasons for loneliness and identify personalized activities most likely to impact loneliness. The primary activity is 'action planning,' which involves selecting a social goal for the week, brainstorming ways to meet the goal, identifying barriers, and selecting specific actions to take before the next session. The first 8 sessions are offered weekly and the final two are monthly booster sessions.
No Intervention: Waitlist Control
Study intervention (coaching) is provided after study completion (assessments)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
