Brief Summary

Suicidal thoughts, suicide attempts, and suicide are increasingly common in adolescence. Current face-to-face prevention approaches are of limited effectiveness, rely on extensive resources, and are at odds with adolescents' digital preferences. We will evaluate two unconventional but promising interventions delivered to 13- to 17-year-olds: transcutaneous vagus nerve stimulation to target emotion dysregulation, and a peer-support smartphone app to combat social isolation. If effective, these digitally-delivered interventions could reach far more adolescents at far lower cost than current approaches.

Outcome Measures

Primary Outcomes (1)

  • Changes from Baseline to Follow-up Assessments in Self-Injurious Thoughts and Behaviors over one year

    Teens will be assessed at baseline visits for self-injurious thoughts and behaviors (non-suicidal self-injury (NSSI), suicidal ideation (SI), suicide attempts (SA)). They will complete measures individually on the Qualtrics Survey (SIQ) as well as participate in a face-to-face interview with a trained staff member to assess their level of NSSI, SI, and SA (CSSRS, DSHI). All participants will repeat these tasks at all visits (post-treatment, one-year follow-up). We expect teens who have used the active tVNS device will show improved responses (e.g., decreases in NSSI and SI). Teens who have engaged in the peer-matched MindTiles condition will show improved responses in SI, SA, and NSSI. For both conditions we will examine rates of self-injurious thoughts and behaviors in the treatment arms in relation to national norms. We plan to examine between group change across treatment groups as well as within-person change at 30 days and one year post intervention.

Study Arms (4)

tVNS Program + Control app

EXPERIMENTAL

Adolescents will self-administer 30-minute tVNS (i.e., nerve stimulation) sessions daily for 30 days. They will receive a daily text message on their phone to remind them about their session. They will have access to MindTiles where they will complete daily puzzles on their own. In addition, they will answer a 2-3 minute self-report survey on their current thoughts, feelings, and behaviors once a day for 30 days. They will receive a text message with a link to Qualtrics, a secure online platform where they will complete the survey.

Device: tVNS Program

Phone App Program + Sham tVNS

EXPERIMENTAL

Adolescents will use a specially designed phone app (MindTiles) to communicate with peer to help them cope with emotions, and to foster connection with peers to establish social connections. In addition, they will answer a 2-3 minute self-report survey on their current thoughts, feelings, and behaviors once a day for 30 days. They will receive a text message with a link to Qualtrics, a secure online platform where they will complete the survey. Adolescents will also self-administer 30-minute sham tVNS (i.e., nerve stimulation) sessions daily for 30 days; these sessions will include no actual stimulation.

Interventions

Participants will use the Neuvana Xen device 30 minutes a day for 30 days. The device delivers stimulation through the left ear via an ear bud. Participants can use the device at any time of day.

tVNS Program + Control app

Participants will have access to a specially designed phone app (MindTiles) in order to play a game designed for this study. Participants in the active intervention will be able to connect with a fellow participant who is matched as their peer for social support and they will complete a daily puzzle together and respond to a conversational prompt to encourage communication.

Phone App Program + Sham tVNS
tVNS and Phone App ProgramCOMBINATION_PRODUCT

Participants will have both the Neuvana Xen Device and the full version of our program's phone app. They will use the device and full app access for 30 days.

tVNS and Phone App Program

Participants will have access to our program's phone app so the can complete the daily puzzle on their own. They will also engage in a sham tVNS session for 30min per day for 30 days during which no stimulation is provided.
