Dialectical Behavior Therapy for Adolescents With Self-harm and Suicidal Behavior- an Open Trial

The goal of this pre-post-follow-up study is to examine how well the treatment Dialectical behavior therapy for adolescents (DBT-A) with a duration of 20 weeks for adolescents with self-harm and suicidal behavior works in routine clinical practice. The main questions it aims to answer are: * to investigate how well DBT-A works after treatment and at 3-month follow-up, measured by episodes of self-harm, suicide attempts, depressive symptoms and quality of life, drop-out from treatment and number of possible participants who decline DBT-A. * to investigate how well DBT-A works at 12 months follow-up * to investigate whether pre-treatment factors can predict who will benefit from treatment

Self-harm and suicidal ideation are prevalent among adolescents and associated with major mental health problems and adverse life events. Dialectical behavior therapy for adolescents (DBT-A) is an empirically supported treatment for self-harm and suicidal ideation in adolescents. However, knowledge is scarce on the effectiveness, long-term outcomes, acceptability, and dropout of DBT-A when implemented and delivered as part of routine clinical practice in the Norwegian national health care system. The main aim of this study is to examine the outcomes from DBT-A in terms of self-harm episodes, suicide attempts, and emergency hospital admission, in addition to acceptability and dropout, when DBT-A is delivered at the Department of Child and adolescent psychiatry (PBU), Haukeland University Hospital (HUS). The study is an uncontrolled pre-post study with one-year follow-up and includes three aims: to evaluate outcomes of DBT-A up to three months post-treatment, at one-year follow-up, and to describe predictors of outcome for adolescents receiving DBT-A.
