What CBT actually is
CBT is a short-to-medium-term form of psychotherapy built on a simple idea. Thoughts, feelings, and behaviors influence each other. If you change a behavior, the feeling shifts. If you challenge a thought, the behavior often follows. CBT uses structured techniques to make those changes deliberately.
A typical CBT course runs eight to twenty weekly sessions, with practice between sessions. Each session is goal-directed. You and the therapist identify a target (a fear, a low-mood pattern, a compulsive behavior), build a model of what’s keeping it going, and use techniques to change it.
What CBT looks like in practice
Sessions usually combine three ingredients. First, identifying thoughts that show up in moments of distress and examining whether they’re accurate, helpful, or worth holding. Second, planning behavioral experiments that test what happens when you act differently. Third, structured practice between sessions, sometimes called homework, that builds the new pattern outside the therapy room.
CBT is among the most-researched psychotherapies. It has strong evidence for depression, generalized anxiety, social anxiety, panic disorder, OCD (where a specialized form called exposure and response prevention is used), PTSD, insomnia, and several other conditions.
What CBT isn’t
CBT isn’t unfocused talk therapy, isn’t about reliving childhood, and isn’t a single rigid script. It’s a family of approaches that share the same core logic and adapt to the condition being treated. A clinician who says they “do CBT” should be able to describe the model they’re using and the targets they’re working on.

Exposure therapy is a CBT technique that’s the gold standard for anxiety disorders. Behavioral activation is a CBT approach focused on depression. DBT is a related approach developed for emotion regulation and self-harm patterns.
When to seek professional care
CBT is delivered by a licensed therapist with training in the approach. If you’re considering therapy, asking specifically about a clinician’s training in CBT or in the specific protocol for your condition is reasonable and useful.
When this word matters
The label matters when comparing therapy types, since CBT is a structured, evidence-based approach focused on changing unhelpful thoughts and behaviors, which differs from insight-focused or skills-focused methods. It comes up a lot alongside DBT and exposure therapy, which build on or branch from it.
