Dialectical Behavior Therapy (DBT) is a type of CBT which focuses on "emotional regulation". DBT is helpful when patients, often in their teens, have trouble managing intense feelings. It may be difficult (and expensive) to find therapists who are well versed in DBT and I recommend the book "The Dialectical Behavior Therapy Skills Workbook" by McKay, Wood & Brantley as a great first step.
Behavioral Activation (BA) helps patients recognize patterns of avoidance which prevent recovery (e.g. staying in bed all day). BA relieves depression because what we DO affects how we FEEL. An "Activity-and-Mood Chart" monitors behaviors and patients explore alternative activities and coping strategies. Baby steps are taken. Rumination, a feature of depression is a behavior that requires replacement.
I recommend the BA Workbook "Overcoming Depression: One Step at a Time" by Addis and Martell.
Cognitive Behavioral Therapy (CBT) is a form of psychotherapy which helps patients to identify the irrational and unreasonable self talk which leads to depression and anxiety. CBT teaches patients how to identify and then change this negative self-talk in a simple and effective manner. The booklet "Psychotherapy: A Cognitive Approach" will show you how!
