Cognitive behavioral therapy, or CBT, often comes up when people look for counseling. It involves noticing what you think and do in difficult situations, then trying different responses and reviewing what happens.

What is cognitive behavioral therapy? #

Cognitive behavioral therapy (CBT) starts from the idea that how you interpret an event influences your feelings and actions. If your manager replies late, thinking “They must be busy” may let you move on; thinking “My report must have been terrible” may make you anxious and delay your next report.

CBT often focuses on patterns that are causing difficulties now, while considering relevant past experiences. You and the therapist agree on goals and try practical exercises in and between sessions. Structure and collaboration also occur in other forms of therapy.

CBT methods: what are the steps of treatment? #

1. Agree on difficulties and goals — decide with the therapist what is hardest right now and what you would like to be different by the end of treatment.
2. Map the cycle — pick a recent difficult situation and write down, in order, the thought that came up, your feelings and body reactions, and what you did next.
3. Practice techniques — in sessions, practice techniques suited to the problem, such as examining unhelpful thoughts or gradually returning to activities you have been avoiding.
4. Practice between sessions — try what you learned in daily life and note it in a worksheet or diary. The NHS says this practice is important for CBT to work.
5. Review and adjust — check progress toward your goals together and decide what to cover next and how many sessions remain.

CBT can be one-to-one, in a group, or guided self-help. Each session draws on the techniques below that fit the problem you are working on.

Common techniques used in sessions

A fictional thought-record example

This example explores another plausible explanation, rather than forcing a positive one. The numbers are illustrative: your feelings may change a little, stay the same, or need more time. The useful question is whether the exercise helps you choose a next step.

Spotting the first thought that comes up is covered in our automatic thoughts guide, common thinking patterns in types of cognitive distortions, and a fully filled-in worksheet in our CBT thought record example.

How effective is cognitive behavioral therapy? #

CBT has a substantial research base across several difficulties. Hofmann and colleagues’ 2012 review of meta-analyses found evidence in areas including anxiety disorders and stress. Results vary by condition, study design, and the approach being compared.

Cuijpers and colleagues’ 2013 review found benefits for adult depression compared with control conditions, while comparisons with other treatments were more nuanced. Discuss the evidence relevant to your own concern rather than assuming one therapy is always the best option.

How does CBT for depression work? #

During depression, thoughts such as “Nothing I do works out” that cast yourself and the future in a dark light come up often, and cutting back on activities because of low energy can deepen low mood. CBT for depression therefore usually works on both sides: thought records to check how well those thoughts fit the facts, and behavioral activation to plan small, meaningful activities and gradually increase them.

As in the meta-analysis above, CBT is an established treatment for adult depression, and when symptoms are severe it may be combined with medication. Care options are covered in our depression treatment guide, and ways to increase activity when energy is low in our behavioral activation guide.

What is different about CBT for insomnia (CBT-I)? #

CBT for insomnia is CBT adapted for sleep. It combines stimulus control to rebuild the link between bed and sleep, sleep restriction to adjust time spent in bed, cognitive techniques for worries and beliefs about sleep, and sleep hygiene and relaxation. The American College of Physicians recommends it as the first treatment for chronic insomnia in adults.

Sleep restriction needs attention to daytime sleepiness and safety, so it is best done in consultation with a clinician. The five components and the research are covered in our CBT for insomnia (CBT-I) guide.

How long does CBT take? #

The NHS describes a usual range of 5–15 sessions, depending on the reason for treatment; some plans are shorter or longer. Ask how progress will be reviewed and what practice between sessions would involve. A plan should be adjusted if it is not helping or is difficult to follow.

How much does CBT cost? Health insurance in South Korea #

In South Korea, national health insurance coverage for certain CBT services in psychiatric care was expanded in 2018. The announcement linked below is historical background, not a current price quote or a promise that every CBT service is covered.

Ask the provider about the current fee, any referral requirements, coverage, and limits before booking. Private counseling services and medical services can have different arrangements. Our counseling cost guide discusses the Korean context; readers elsewhere should check local services.

Who provides CBT? Checking a therapist’s credentials #

CBT is delivered by mental health professionals with relevant training, such as psychiatrists, clinical psychologists, and counselors. In South Korea, the Korean Association of Cognitive Behavioral Therapy runs two society credentials: CBT specialist and CBT therapist.

Detailed criteria follow the society’s credential rules, and its website lists CBT specialists. When choosing a therapist, also ask how much CBT they have actually practiced and whether they have worked with difficulties like yours.

How can I decide whether it suits me? #

• Your goals: Describe what you would like to be different in daily life, even if you are unsure which therapy to choose.
• Your preferences: Explain whether practical exercises appeal to you and where you need more time for discussion or support.
• Your clinical needs: Severe or complex symptoms may call for additional assessment or combined treatment. A qualified clinician can help plan this.

You can ask a therapist to explain why they recommend a particular approach and how they would adapt it to your needs. Feeling heard, understanding the plan, and being able to discuss difficulties with the exercises all matter.

How can an app fit into everyday practice? #

Books, worksheets, and apps can make it easier to revisit an exercise between conversations or appointments. A 2019 review of 66 randomized trials found small average benefits from the smartphone interventions studied. Those results concern the specific interventions and support arrangements tested; apps vary in design and purpose.

CareOps Maeumi is an AI counseling app where you can explore thoughts and small action plans through conversation. Its conversations draw on approaches including CBT. For a related way to work with difficult thoughts, see our ACT guide. Our AI counseling guide explains what to look for when choosing an app.
