It is one of the best-studied therapies in the world. A review of 269 meta-analyses found the strongest support for anxiety disorders, bulimia, anger and general stress (Hofmann et al., 2012), and a 2023 meta-analysis of 409 trials with 52,702 patients found a moderate-to-large effect on depression (Cuijpers et al., 2023).
It is not magic, and not the only option. Effects shrink in the best-quality trials, CBT is generally about as good as other proper therapies and antidepressants in the short term, and around a third of people treated for depression relapse (Wojnarowski et al., 2019).
You will find the full evidence, with sources, in the complete guide.
Before you start: CBT is generally safe but can have unwanted effects: in a study in which 100 CBT therapists described one patient each, side effects judged to be caused by the therapy were reported for 43 of 98 patients, most often distress or reduced wellbeing. Feeling worse before better is common with exposure or trauma-focused work, so tell your therapist if it feels too much. If you are in crisis or thinking of harming yourself, contact your local emergency number or find a helpline in your country at findahelpline.com (in the US, call or text 988).
Read our complete guide first. It explains CBT step by step and says plainly what the evidence does and does not show.
How many sessions of CBT will I need?
Most courses last between 5 and 20 sessions of about an hour, weekly or fortnightly. Low-intensity guided self-help may be six to eight shorter sessions, while complex or long-standing problems may need more. Your therapist should agree a plan and review progress with you.
How long does CBT take to work?
Many people notice some change within the first six to eight sessions, especially if they practise between sessions. It's normal for progress to be uneven. If nothing has changed after several sessions, raise it with your therapist.
Can I do CBT on my own?
Yes. Self-help books, workbooks and evidence-based online programmes are recognised first steps for less severe problems. Thought records, activity scheduling and gradual exposure are all things you can try. For moderate or severe difficulties, or if self-help isn't working, get professional support.
What are thinking traps in CBT?
Thinking traps, or cognitive distortions, are common biased patterns of thinking, such as all-or-nothing thinking, catastrophising, mind reading and "should" statements. Learning to recognise and name them makes it easier to step back and find a more balanced view.
Does CBT work for everyone?
No. CBT helps many people, but a significant minority don't improve much, and around a third of people treated for depression relapse. Results depend on the problem, the therapist's skill and how well the approach fits you. Other therapies, such as behavioural activation, ACT or psychodynamic therapy, may suit some people better.
Can CBT make you feel worse?
Sometimes, temporarily. Facing fears or painful memories can raise distress before it falls, and a small number of people experience lasting side effects. Tell your therapist if you feel worse, and get urgent help if you feel unsafe.
