Key Takeaways
Cognitive Behavioural Therapy (CBT)
Cognitive Behavioural Therapy, commonly called CBT, is a structured, goal-focused form of talking therapy. It works on the idea that our thoughts, feelings, and behaviours are closely connected — and that changing unhelpful thinking patterns can improve how we feel and act. CBT is typically short-term and practical, meaning sessions involve real exercises, not just open-ended conversation.
CBT is grounded in decades of clinical research and is recommended by major health bodies, including the American Psychological Association, for conditions such as depression, anxiety disorders, and PTSD.
The Core Idea Behind CBT
CBT is built on one central insight: our thoughts are not facts. When we feel anxious, depressed, or stuck, it is often because we are running on automatic thinking patterns that distort how we see ourselves, others, and the future. CBT helps you notice those patterns and test whether they are actually true.
The therapy works across three connected layers:
- Thoughts (cognitions): What you say to yourself, often automatically
- Feelings (emotions and physical sensations): How those thoughts make you feel in your body and mind
- Behaviours: What you do — or avoid doing — as a result
These three elements feed each other. A negative thought can trigger an anxious feeling, which leads to avoidance behaviour, which reinforces the original thought. CBT interrupts that loop. If you are curious about how CBT compares to other approaches, our guide to different types of therapy offers a useful overview.
CBT Is Not One-Size-Fits-All
CBT is highly adaptable, but it is not the right fit for everyone. Some people prefer approaches that focus more on the past or on the therapeutic relationship itself. If you are unsure whether CBT suits you, a qualified therapist can help you explore your options. Our article on what therapy actually is is a good starting point for setting realistic expectations.
What Actually Happens During a Session
A CBT session typically lasts 45 to 60 minutes. Unlike some therapy styles, CBT sessions have a predictable structure, which many people find reassuring — especially at the beginning.
Here is what a typical session might include:
- Check-in: Your therapist will ask how you have been since the last session and review any exercises you tried.
- Setting the agenda: Together, you agree on what to focus on that day. Both you and your therapist contribute to this.
- Working through a specific issue: You might examine a recent situation where you felt distressed, map out what thoughts were present, and explore whether those thoughts were balanced or skewed.
- Practising a skill: Your therapist may introduce a technique — such as a thought record, behavioural experiment, or grounding exercise — and walk you through it.
- Agreeing on between-session tasks: You will typically leave with something small and practical to try before next time.
CBT is a collaborative process. Your therapist is not there to tell you what to think — they help you examine your own thinking more clearly. For a broader picture of what to expect when beginning any therapy, see our complete introduction to starting therapy.
Make the Most of Between-Session Tasks
Research consistently shows that people who complete between-session exercises tend to get more out of CBT. You do not need to do these perfectly — even a partial attempt gives you and your therapist valuable information to work with. Treat them as experiments, not tests.

Common CBT Techniques You Might Encounter
CBT draws on a toolkit of well-researched methods. Not every technique will be used with every person — your therapist will tailor the approach to your specific goals.
Thought Records
You write down a situation, the automatic thought that followed, the emotion it triggered, and then generate a more balanced perspective. Over time, this builds a habit of pausing before reacting.
Behavioural Experiments
You test a belief by doing something you would normally avoid. For example, if you believe a social situation will go badly, you try it in a small, manageable way and observe what actually happens.
Graded Exposure
For anxiety, CBT sometimes involves gradually facing feared situations in a planned, stepwise way — reducing avoidance without overwhelming you.
Activity Scheduling
For low mood, scheduling small enjoyable or meaningful activities can help break cycles of withdrawal and low motivation.

Response rate for CBT in depression
Meta-analyses published in leading psychology journals suggest around half of people with depression show meaningful improvement following a course of CBT.

Typical number of CBT sessions
Clinical guidelines from the American Psychological Association and similar bodies note that CBT is generally a short-term intervention, with many people completing treatment in under six months.

Randomised controlled trials supporting CBT
CBT is among the most extensively researched psychotherapies, with hundreds of controlled studies examining its effectiveness across different conditions and populations.
CBT also has close relatives worth knowing about. Acceptance and Commitment Therapy (ACT) takes a different angle, focusing on psychological flexibility rather than directly challenging thoughts. Dialectical Behaviour Therapy (DBT) blends CBT methods with acceptance strategies, particularly for intense emotions. If you are managing anxiety specifically, our guide to therapy options for anxiety explains how these approaches compare.
