Adolescent nonsuicidal self-injury (NSSI) and alcohol misuse, alone and especially in combination, portend significant functional impairment in adulthood (e.g., relationship dysfunction, depression, suicidality). Although psychosocial interventions for NSSI and substance use are effective for some, they are also expensive and require highly trained clinicians. Treatment is therefore often unavailable to disadvantaged adolescents and those who live rurally. Thus, lower-cost alternative treatments are needed. We will evaluate the efficacy of noninvasive transcutaneous vagus nerve stimulation (tVNS), an effective treatment for depression, in reducing risk for NSSI and substance misuse among vulnerable adolescents.
