Can teaching teens two simple skills reduce Self-Harm?

This study enrolls 200 teens with a history of self-inflicted injury, including at least one suicide attempt. Researchers will teach two skills from Dialectical Behavior Therapy (Opposite to Emotion Action and GIVE) and track how often teens use them in daily life via phone surveys. They will also measure brain activity with fMRI, family interactions, and stress levels to understand what helps skills stick. The goal is to learn how these skills work, not to test a new drug or cure.
