Starting therapy can feel like stepping into the unknown. Most people arrive at their first session with some combination of nervousness, relief, and uncertainty about what is actually going to happen. The good news is that there is nothing mysterious about CBT — it is a structured, practical approach, and your therapist will explain clearly what you can expect at every stage. Here is what the process typically looks like.

The consultation versus the first session

If you have booked a free consultation beforehand, that is a brief 15-minute call to check fit — whether your concerns are something CBT can help with, and whether you feel comfortable with your therapist. It is not a therapy session; no notes are taken and nothing gets recorded. Think of it as a practical conversation to help you decide whether to proceed.

The first full session is different. This is a proper 50-minute appointment, and it serves a specific purpose: assessment. Your therapist will be trying to understand your situation in enough detail to form a shared picture of what is going on and agree a direction for the work ahead.

What forms you might be asked to fill in

Many CBT therapists ask clients to complete short questionnaires before or at the start of the first session. These are usually standardised measures — for example, the PHQ-9 for low mood or the GAD-7 for anxiety. Do not be put off by this. They are not pass/fail tests. They help establish a baseline so that both you and your therapist can track whether things are improving over time. Completing them honestly gives you the most useful information.

Questions your therapist is likely to ask

Assessment in CBT is conversational rather than clinical. Your therapist will probably ask about the main difficulty you want to work on, when it started, and how it affects your day-to-day life. They will want to know what happens in your mind and body when the problem is at its worst — what you think, how you feel physically, and what you do (or avoid doing) as a result. They may also ask briefly about your background, your relationships, and whether you have had any previous experience of therapy.

None of this is interrogation. A good therapist is listening carefully and building a picture, not judging. If there is something you would rather not discuss in the first session, it is fine to say so.

How to prepare

You do not need to prepare a polished account of your life history. The most useful thing you can do is spend a few minutes beforehand thinking about what you most want to change. What has prompted you to seek help now, rather than six months ago? What would a successful outcome look like — not in vague terms, but specifically? Being able to say "I want to be able to go to work without three hours of anxious checking every morning" gives your therapist much more to work with than "I want to feel less anxious."

It can also help to note any practical constraints: how many sessions you can afford, whether there are particular times of day the problem is worse, or any upcoming events you are already anxious about. Your therapist will want to know these things.

The structure of the session itself

A typical first CBT session follows a rough shape. After a brief introduction and orientation — covering how sessions work, confidentiality, and what to expect — most of the time is spent on the assessment conversation described above. Towards the end, your therapist will usually share their initial understanding of the problem and check whether it resonates with you. This is the beginning of the shared formulation that CBT is built on.

You will also be asked what you want to get from the work, and your therapist will offer some initial thoughts on how CBT might help. There may be a brief discussion of how many sessions are typically needed for your kind of difficulty — this varies considerably, but a realistic range for anxiety-related problems is often 8 to 16 sessions.

Taking notes and homework assignments

CBT is not a passive experience. From the very first session, you can expect your therapist to encourage you to track your experiences between appointments. This might start with something straightforward — a simple thought diary where you note down situations that triggered anxiety, what you thought at the time, and how you responded. Do not overthink this. The aim is not to produce a literary account but to gather information that both you and your therapist can use.

These between-session tasks are sometimes called homework, though many therapists use other terms. Whatever the name, they matter. Research consistently shows that clients who engage with between-session work progress faster and maintain their gains more reliably. Your therapist will always explain the rationale behind a task and will never set something that feels unreasonable or overwhelming.

What to take away from the first session

By the end of your first appointment, you should have a clearer sense of whether CBT feels right for you, a preliminary shared understanding of your difficulties, and some idea of what the next few sessions might involve. You are under no obligation to continue if it does not feel like a good fit. CBT requires genuine engagement and collaboration — if the relationship does not feel right, it is worth saying so or seeking a different therapist.

Most people leave a first session feeling a combination of things: some relief at having started, perhaps some emotional tiredness from talking about difficult material, and hopefully a degree of optimism that there is a structured approach that can help. That combination is normal, and it is a reasonable place to begin.
