What Is CBT and How Does It Work?

If you've been recommended CBT, by a GP, a friend, or after your own research, you might be wondering what it actually involves. It can sound clinical and abstract. This post explains it plainly, so you know what to expect before you take that first step.

CBT stands for Cognitive Behavioural Therapy. It's based on a straightforward but powerful insight: the way we think affects the way we feel, and the way we feel affects what we do. These three things, thoughts, feelings and behaviours are in constant conversation with each other.

When we're struggling, we often get caught in patterns where unhelpful thoughts lead to difficult emotions, which lead to behaviours that make things worse, which then feed back into our thinking. CBT helps you identify these patterns and, step by step, start to change them.

The cognitive part refers to your thinking your interpretations, beliefs, assumptions and inner dialogue. The behavioural part refers to what you do, including things you avoid. CBT works with these patterns directly, not just by talking about them but by changing them.

CBT sessions are structured. We typically spend the first part reviewing how the week went and any tasks from the previous session. We then focus on a specific issue, a difficult thought pattern, a situation you've been struggling with, a behaviour you want to change. By the end of the session you usually have something concrete to take away and try before next time.

This is one of the key differences between CBT and some other forms of therapy: there is usually work to do between sessions. Not homework in the school sense, more like experiments and reflections that help you practise new ways of responding in real life, where it actually matters.

CBT has one of the strongest evidence bases of any psychological therapy. It is the treatment of choice recommended by NICE (the National Institute for Health and Care Excellence) for anxiety, depression, panic disorder, social anxiety, OCD, PTSD and trauma, health anxiety, phobias, and sleep difficulties. It also has a growing evidence base for supporting autistic and ADHD individuals, though adaptations are needed to make it genuinely accessible and effective which is something I specialise in.

CBT is typically a shorter-term therapy than some others. Many people find 6–16 sessions helpful depending on what they're working on. That said, there's no rigid rule, some people prefer to work for longer, and some difficulties resolve more quickly. After an initial assessment I'll give you a clearer sense of what might be useful for your situation.

CBT works well for many people, but not everyone, and not for every difficulty. It requires a degree of engagement between sessions, which suits some people well and others less so. It's also a fairly structured approach, which some people find helpful and others find constraining. I'll always be honest about whether CBT is right for you, and help you find the right support.
