The investigators method is a randomized, controlled study that includes 30 patients with suicidal behaviors and 15 healthy controls between the ages of 12 and 18 years. Patients were assigned to one of two groups (randomized): DBT and Regular Support Therapy. Clinical and neuropsychological evaluations were performed before and after the treatment for both patient groups. Additionally, Structural MRI data sets, diffusion-tensor imaging (DTI) and Functional Connectivity (Resting State fmri) were acquired for all patients and controls at baseline and after treatment. Initial characteristics will be compared between the three groups, and the investigators will also compared clinical, neuropsychological and imaging measures before and after the treatment.
