Leverage Noninvasive Transcutaneous Vagus Nerve Stimulation to Reduce Suicidal Behaviors in Vulnerable Adolescents

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.
