Brief Interventions on Social Media to Reduce Suicide Risk (Intervention 1)

August 8, 2025 updated by: Matthew Nock, Harvard University

Analysis of a Peer-to-Peer Support Social Media Platform for Service Members and Veterans of the U.S. Military: Intervention 1 (Peer Support)

This clinical trial is part of a series of brief interventions to reduce suicide risk in collaboration with the social media platform RallyPoint, a site specifically designed for U.S. servicemembers and veterans to connect with one another. In this RCT (Intervention 1: Peer Support), the investigators will test a psychoeducational intervention aimed at increasing peer responses to RallyPoint posts that a machine learning risk algorithm developed by the current team has identified for signs of distress (e.g., descriptions of suicidal thoughts and behaviors or other mental health concerns). In this intervention, the investigators will flag these distressed posts and prompt peers to reply to the posts by providing informational blurbs detailing helpful peer responses.

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.

Detailed Description

Both active duty and veterans of the United States military are at elevated risk for the development of psychological disorders such as depression, posttraumatic stress disorder, alcohol and substance use disorders, and suicide. Despite the clear need for psychological interventions for this population, only a small proportion of veterans utilize the Veteran's Affairs Health Care System for psychiatric care. Further, most people who are at-risk for suicide do not present for mental health treatment prior to their deaths. There are several reasons why military personnel may not seek out treatment, including stigma of mental health care, or structural barriers such as availability of treatment. Prior research from the current team comparing Army soldiers who died by suicide to matched control soldiers found that suicide decedents were more likely to perceive concerns that receiving mental health care would hurt their careers, reduce others' confidence in them, or lead others to see them as weak.

To increase the likelihood that veterans and servicemembers receive the help they need, one option is to harness technology to assess and treat mental health concerns outside of traditional healthcare settings. Social media platforms may be a particularly promising avenue for identifying and providing outreach to at-risk individuals, given research suggesting that peer support may be preferable to professional mental health treatment. In fact, a recent survey of military servicemembers conducted by the Defense Equal Opportunity Management Institute, servicemembers indicated that when they are feeling stressed, they prefer to speak with peers or spouses/partners (48-54%) rather than medical or mental health professionals (4-7%). Social media platforms may offer a scalable way of identifying and helping at-risk individuals.

In the current project, the investigators have partnered with the military-specific social media site RallyPoint (www.rallypoint.com) in order to determine how to best support at-risk veterans and servicemembers. The investigators will be testing three brief interventions aimed at connecting RallyPoint users to peer and professional resources:

Intervention 1: Peer support (current intervention): This intervention will aim to improve RallyPoint users' ability to support their peers.

Intervention 2: Stigma-reduction intervention: This intervention will focus on reducing barriers that are inhibiting members in distress from reaching out to their peers.

Intervention 3: Professional Outreach: This last intervention will aim to reduce barriers that are inhibiting members in distress from seeking professional mental health support.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
942

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:

  • Individuals who are active users on the social media site RallyPoint.

Exclusion Criteria:

  • Individuals who are not active users on the social media site RallyPoint.

Arms and Interventions

Participant Group / Arm

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.
No Intervention: Control
Half of RallyPoint's active users will comprise the control group. The control group will not be shown the intervention flags and will see posts displayed as usual.
Experimental: Intervention
Participants will not be actively recruited for this intervention. Rather, about half of active RallyPoint users (approximately 40,000 users; 80,000 users total) will be randomized to see the Intervention #1 psychoeducational pop-ups. The investigators will work with RallyPoint collaborators who will only display the distress flags to participants in the intervention group. RallyPoint users will not see flags appear on their own concerning posts, if they make any. The intervention will last up to six months (i.e., flags will be visible on concerning posts made over a six month period).
Behavioral: Peer support intervention
Flags will appear beside posts that the risk algorithm has identified as containing descriptions of distress or mental health concerns (these flags will not be visible to the original poster). Next to these flags, users will also see a brief blurb such as: "This person might be going through something difficult. To learn more about what to say to peers who may be experiencing distress, click this banner." RallyPoint users will then have the option of clicking on these flags, where they will be directed to a psychoeducational information page on how to provide support to peers who may be experiencing distress.
