What is CBT?

The thought, feeling and action loop

How you feel about a moment depends partly on how you read it, and what you do next can keep that reading going. The psychiatrist Aaron Beck developed cognitive therapy in the 1960s after noticing that his depressed patients' thoughts followed repeating patterns.¹ The behavioral half, changing what you do, was built in from the start, with techniques such as planning activities week by week.²

CBT works on two points in that loop. The cognitive part looks at the thought: what fits it, what doesn't, and what else could be true. The behavioral part changes the action, often as a small test of what happens.

The main techniques you'll meet:

• Thought records, for writing a thought down and weighing it. You can fill one in here.
• Behavioral activation, which schedules small, doable activities when low mood makes everything feel pointless.²
• Behavioral experiments, where you test a belief by doing something and seeing what happens.³
• Exposure, for fears: facing a feared situation in steps, so you learn that what you expected doesn't happen, or that you can cope with it.⁴

The thinking patterns CBT looks for, such as catastrophizing and should statements, are listed on the cognitive distortions page.

Inside a session

In England's NHS, people usually have between 5 and 15 sessions, depending on what the CBT is for.⁵ In a typical session you talk about situations you find hard and look at how they affect your thoughts, feelings and actions, then find different ways to approach them.⁵

Sessions are structured and present-focused. You and the therapist work together on goals, track progress, and agree on an action plan, the CBT word for practice between sessions.⁶

A first few sessions might go like this:

1. Session one: you describe what's been hard and what you'd like to be different. Together you set two or three specific goals, such as "go back to the gym twice a week" or "sleep before midnight."
2. The next few: you bring a recent moment, such as an argument or a night of worry, and pull it apart. What happened, what went through your mind, what you felt and what you did.
3. Between sessions: you try something small, like a thought record after a hard moment, or a test of one belief.
4. At the next session: you start with what happened when you tried it.

An action plan at the end of a session might sound like this, as an example:

CBT can be done one to one, in a group, online or as guided self-help. In 13 studies that compared them directly, therapist-guided internet CBT and face-to-face CBT had about the same effect.⁷

How well CBT works, and for whom

CBT is by far the most studied talking therapy for depression.⁸ Being the most studied is a different thing from being the best choice for everyone, and the trials themselves show where the line falls.

Stefan Hofmann and colleagues found 269 meta-analyses of CBT and reviewed 106 of them, and the strongest support was for anxiety disorders, somatoform disorders (physical symptoms without a clear medical cause), bulimia, anger and general stress.⁹

For depression the evidence is large and consistent. A 2023 analysis of 409 trials with 52,702 patients found moderate to large effects compared with usual care or waiting lists, still present 6 to 12 months later.⁸

Against other therapies, though, CBT's edge for depression was small and disappeared in most of the stricter checks.⁸ Another well-tested therapy may suit you just as well.

Against medication, CBT for depression did about as well in the short term, and somewhat better 6 to 12 months later, though few trials measured that.⁸

It hasn't got much better with time. For anxiety disorders, CBT's effect against placebo-type comparisons has stayed about the same across 30 years of trials.¹⁰

And there are gaps. Apart from children and older adults, almost no meta-analyses had looked at specific groups, such as ethnic minorities or people on low incomes, when the 2012 review was done.⁹

An average effect means that many people improve and some don't. If CBT isn't helping after a fair try, say so to your therapist, since a good therapist will want to know.

CBT vs DBT

DBT, dialectical behavior therapy, is a form of CBT, built by Marsha Linehan for people whose emotions are intense and hard to manage, and first tested in 1991 with women with borderline personality disorder who repeatedly harmed themselves.¹¹ On top of CBT's methods it teaches skills in mindfulness, interpersonal effectiveness, emotion regulation and distress tolerance.¹² The CBT vs DBT page goes through the trials for each.

If you're not sure which fits, describe what's hard for you and ask the therapist which approach they'd suggest and why.

How to find a CBT therapist

Plenty of therapists list CBT. Two questions sort the ones who practice it: "What does a typical session look like?" and "Will we do practice between sessions?" A CBT therapist should be able to answer both plainly.

Four places that go beyond the general search:

• The Association for Behavioral and Cognitive Therapies keeps a Find a CBT Therapist directory of its licensed members. It isn't a complete list, and it doesn't rate anyone.¹³
• Your insurer's directory. Call the number on your card and ask for therapists who offer CBT.
• An Employee Assistance Program, if you have a job, which NIMH describes as a free and confidential service your employer pays for.¹⁴
• Open Path Collective, which lists sessions from $40 to $70 after a one-time $65 membership, for people without insurance or whose coverage doesn't cover enough. Prices checked October 29, 2026.¹⁵

In England, you can refer yourself to NHS Talking Therapies if you're 18 or over (16 in some areas).⁵

How journaling fits between sessions

Much of the work in CBT happens between appointments, and the people who do more of that practice have better outcomes, a link that showed up across 17 studies.¹⁶ The hard moments don't always land on a Thursday at 4 p.m., which is part of why Joyful exists; Joel's story tells the rest.

A journal between sessions can hold:

• Thought records from the hard moments, so you bring the exact words to your next session.
• A worry log with check dates, so you can see what happened to each worry.
• Behavioral experiment notes: what you predicted, what you did and what you found out.

Free printable versions are on the CBT worksheets page. Joyful is an AI journaling companion with guided CBT entries, including a thought record, and summaries of the thinking patterns in your entries. It's a journal, not therapy, and it can't replace a therapist.

Questions people ask

What are the 5 stages of CBT?

There's no single official five-stage model. A helpful way to picture a course is that it moves through getting to know the problem, setting goals, working on thoughts and behaviors, practicing between sessions, and planning for setbacks before ending.

Can I do CBT on my own?

Some people can. In the 2023 depression analysis, unguided CBT self-help still had a moderate effect on average.⁸ If you try it alone and things aren't improving after a few weeks, or they're getting worse, talk to a professional.

How long does CBT take?

Often 5 to 15 sessions in the NHS, depending on the problem.⁵ Some people need longer, and DBT programs often run for a year.¹¹

Is CBT the same as talk therapy?

It's one kind of talk therapy. It's more structured than many others, with goals, a plan for each session and practice in between.
