What to Expect from a Course of CBT (Cognitive Behavioural Therapy)
A guide to how CBT works - from the first session to the final steps
Starting therapy can feel like stepping into the unknown. Whether you’ve been referred by a GP, found a therapist yourself, or are just exploring your options, it’s natural to wonder: What actually happens in CBT?
Cognitive Behavioural Therapy (CBT) is a structured, evidence-based psychological treatment. It’s widely used to support people with difficulties such as anxiety, depression, OCD, PTSD, health anxiety, low self-esteem, and many others. But even though it’s recommended by the NHS and NICE guidelines, many people still feel unclear about what CBT involves.
This post is designed to walk you through what to expect over the course of CBT - what happens in the beginning, middle, and end - along with some common misconceptions we’ll clear up along the way.
The Beginning: Understanding and Planning
The first few sessions of CBT are all about getting to know you - not just as a list of symptoms, but as a whole person. Your therapist will want to understand:
What you’re struggling with day-to-day
What you’ve already tried
What you’d like to be different
How your thoughts, feelings, behaviours, and physical responses interact
Together, you’ll start building a shared picture of the problem, often called a formulation. This isn’t a diagnosis; it’s more like a map. It helps both you and your therapist understand how certain patterns have developed and what might be keeping them going.
You might also set goals around this time. These will be specific and meaningful to you. CBT doesn’t aim for vague improvements like “feel better”, but rather clear and practical changes, such as “go back to work part-time” or “be able to speak up in meetings”.
At this stage, the therapy might feel a bit information-heavy. That’s okay. It takes time to settle in and feel comfortable. The pace should be collaborative - your therapist will check in regularly to make sure it’s feeling useful and manageable.
The Middle: Working on Change
Once the foundation is in place, CBT becomes more active. This is where you begin testing out new ideas and strategies. You might work on:
Spotting patterns – noticing how certain thoughts or behaviours show up in daily life.
Challenging unhelpful thinking – learning to examine your thoughts more objectively, asking questions like “Is this thought accurate?” or “Is it helping me?”
Behavioural experiments – gently testing your fears or assumptions in real-world situations to see what actually happens.
Facing fears gradually – particularly relevant in anxiety-focused CBT, where avoidance might be keeping fears going.
Building up valued activities – reconnecting with the things that give you purpose, joy, or connection.
Developing coping skills – such as assertiveness, problem-solving, relaxation, or emotional regulation techniques.
This part of CBT often involves home practice. That might mean trying a new behaviour, completing a thought record, or simply observing patterns during the week. It’s not about having perfect answers - it’s about learning through experience.
The middle phase can be challenging. Sometimes it stirs things up before they settle. That’s normal - and something your therapist should help you navigate. You won’t be expected to “perform” or “get it right”. Therapy is a process of trying, reflecting, adjusting, and trying again.
The End: Consolidating and Preparing for the Future
As you near the end of therapy, the focus shifts to maintaining progress and preventing relapse. You’ll review:
What’s changed
What’s helped
What you’ve learned about yourself and your patterns
What you’d like to continue practising
Together, you and your therapist will create a relapse prevention plan. This might include:
A summary of key tools and strategies that worked for you
A list of early warning signs that things might be slipping
A plan for what to do if difficulties return
Confidence-building around managing independently
The goal of CBT isn’t to make life permanently problem-free (that’s not realistic). It’s to equip you with practical tools and understanding that help you respond more flexibly to future challenges.
Some people end therapy feeling ready to move forward. Others finish with mixed feelings - grateful, but unsure about managing alone. Your therapist should talk this through with you and ensure a thoughtful, planned ending. You might even have a follow-up session in future to check in.
Common CBT Myths
Therapy comes with a lot of assumptions, media portrayals, well-meaning advice from friends. Here’s the truth behind some of the most common CBT myths:
Myth Number 1: CBT is just ‘positive thinking’
CBT is about realistic thinking, not blind optimism. You’ll learn to recognise when your thoughts are biased, harsh, or unhelpful - and to consider alternatives that are accurate and balanced.
Myth Number 2: CBT ignores your past
CBT focuses on the present, but that doesn’t mean your past is irrelevant. Understanding how early experiences shape current beliefs or coping strategies can be a useful part of the process.
Myth Number 3: CBT only works for people who are logical or good at analysing their thoughts
CBT isn’t just a ‘talking cure’ - it includes behavioural experiments, imagery, mindfulness, and other creative strategies. It’s not about being clever - it’s about being curious.
Myth Number 4: You need to be in therapy for years
CBT is usually short to medium-term. Many people benefit from around 8–20 sessions, although some may need longer. The goal is for therapy to become unnecessary - not a permanent fixture.
Myth Number 5: If you struggle, it means CBT isn’t working
It’s normal to hit bumps along the way. Struggling doesn’t mean failing; it often means you’re confronting something important.
Final Thoughts
CBT isn’t a magic fix. It’s a structured, collaborative, and research-informed approach to making meaningful changes in how you think, feel, and act. Like any meaningful change, it takes effort and commitment; but it also builds skills that can last a lifetime.
If you’re starting CBT soon, I hope this post helps you feel more informed and empowered. If you’ve already completed therapy, perhaps it offers a helpful reflection on what you’ve achieved.
And if you’re still deciding whether CBT is right for you, consider this: CBT doesn’t promise perfection, but it does offer clarity, practical tools, and the possibility of change - even if things have felt stuck for a long time.
