Therapist Aid Substance Use Worksheets – Dialectical behavior therapy (DBT) is a sort of cognitive-behavioral therapy that was established by Marsha M. Linehan to assist people that have trouble regulating their actions as well as feelings. DBT helps individuals identify as well as transform negative idea patterns as well as actions that might be contributing to their problems. One way that DBT practitioners sustain their customers in this process is through the use of worksheets.
