Cognitive-Behavioral Therapy

is a form of psychotherapy that emphasizes the important role of thinking in how we feel and what we do. 

Cognitive-behavioral therapy does not exist as a distinct therapeutic technique. The term "cognitive-behavioral therapy (CBT)" is a general term for a classification of therapies with similarities.  There are several approaches to cognitive-behavioral therapy, including Rational Emotive Behavior Therapy, Rational Behavior Therapy, Rational Living Therapy, Cognitive Therapy, and Dialectic Behavior Therapy, and Mindfulness Based Cognitive Therapy.

CBT is based on the Cognitive Model of Emotional Response.
Cognitive-behavioral therapy is based on the idea that our thoughts
cause our feelings and behaviors, not external things, like people, situations, and events.  The benefit of this fact is that we can change the way we think to feel / act better even if the situation does not change.

Mindfulness-Based and Acceptance Therapies

are designed to help people who suffer repeated bouts of depression and anxiety. They combine the ideas of cognitive therapy with meditative practices and attitudes based on the cultivation of mindfulness and acceptance. The heart of this work lies in becoming acquainted with the modes of mind that often characterize anxiety and mood disorders while simultaneously learning to develop a new relationship to them. MBCT was developed by Zindel Segal, Mark Williams and John Teasdale, based on Jon Kabat-Zinn's Mindfulness-Based Stress Reduction program. ABBT, or Acceptance Based Behavioral Therapy is based on the work of Elizabeth Roemer and Susan M. Orsillo
