About the study

This is a feasibility trial of a digital mental health intervention aimed at adolescents (ages 14-18) with nonsuicidal self-injury and who are not currently engaged in mental health treatment. The study has two arms: a self-guided DMHI and an active control which will involve the delivery of non-interactive psychoeducational content via the same app interface. The primary goals of this project are to evaluate the feasibility of the intervention and trial procedures in preparation for a fully-powered randomized-controlled trial.
