Possible Complications

CBT may not work for everyone. There may be other methods that work better for certain people.

What to Expect

Prior to Procedure

You may be asked to fill out a questionnaire about your feelings.

Description of the Procedure

CBT can be done alone or in a group. CBT can be split into two parts:

Functional Analysis

You and your therapist will identify stressful situations. You will also learn the thoughts that make problems worse. These thoughts will be worked on to see if that is the best way to handle problems. Your therapist may point out negative thought patterns such as “I can't handle this” or "people are laughing at me.”

Skills Training

Next, you will work on lessening negative thoughts. This will help you learn healthier ways. This may involve exposure to the situation that causes your problems. You will learn to draw on your strengths so you can think "I can" instead of "I can't".

You will also learn to ask more questions. For example, “Could those people be laughing at something other than me?” The goal is to replace unhealthy thoughts with healthy ones.

This takes a lot of practice. You will often be given homework. You may have to practice deep breathing or role play how to act. For example, a person dealing with substance abuse might practice ways to say no to alcohol.

Homework is vital to the success of CBT. You must practice new, rational responses until they replace your previous, unhealthy responses. Homework also allows you to try new skills. You will then be able to give feedback on which works best for you.

How Long Will It Take?

One session is usually 50 to 100 minutes. Group sessions may last longer. You may need to go 1 to 2 times per week for 12 to 16 weeks.

Depending on your situation, you may need a longer or shorter time frame. Keep in mind it may take many tries to unlearn poor habits and to learn healthy ones.

Post-therapy Care

You may be given homework between sessions. You will need to practice the strategies you and your therapist have discussed.

Some therapists want you to return for a checkup about 3, 6, and 12 months after therapy has ended. You may call your therapist at any time.


The goal of CBT is to change your thought process. This will allow healthy and realistic responses to difficult situations. Many patients notice an improvement in their symptoms within 3 to 4 weeks of beginning CBT.

Call Your Doctor

If the thoughts, feelings, or other problems that led you to CBT are returning or getting worse, call your doctor. If you have thoughts of hurting yourself or others, call for emergency medical services right away.
