DBT is most commonly applied in the treatment of individuals diagnosed with borderline personality disorder (BPD) or those experiencing challenges with emotional regulation. Nevertheless, it is a versatile treatment with a range of applications and can be integrated into the therapeutic management of various mental health conditions as a sole treatment or to complement other therapeutic inventions or medications. Individuals diagnosed with BPD typically struggle to regulate their emotions, which often leads to tumultuous relationships and poor self-esteem. These emotional struggles may manifest in self-harming behaviors or the presence of suicidal ideation. This form of therapy is beneficial for individuals with various mental illnesses that lead to challenges in managing their emotions or engaging in self-destructive behaviors, including issues such as eating disorders and substance use disorders. Additionally, it is occasionally employed in the treatment of post-traumatic stress disorder (PTSD).
