What is CBT?
CBT, or cognitive behavioural therapy, is a form of psychotherapy that focuses on the connections between our thoughts, emotions, physical sensations and behaviours. Its starting point is simple: two people can react very differently to the same situation depending on how they interpret it.
Imagine sending an important message and not receiving a reply straight away. You might think, “I must have said something awkward.” This interpretation can increase anxiety, create tension in the body and lead you to reread the conversation repeatedly. Someone else might think, “They are probably busy,” and continue their day more calmly. The situation is the same, but the meaning given to it changes the experience.
CBT helps identify these patterns and try out more helpful responses. It is not about convincing yourself that everything is fine or replacing every negative thought with a positive one. Instead, it involves examining what you think, checking whether that interpretation fits the facts and experimenting with other ways of responding.
Where does cognitive behavioural therapy come from?
CBT developed gradually from two traditions. The first was behavioural therapy, which emerged in the mid-twentieth century from research into learning and conditioning. Therapists began applying this knowledge to help people dealing with fears and avoidance behaviours, among other difficulties.
The second tradition was cognitive therapy. In the 1950s, psychologist Albert Ellis developed an approach centred on beliefs and their influence on emotional reactions. In the 1960s, American psychiatrist Aaron T. Beck, who had originally trained in psychoanalysis, observed that people with depression often experienced rapid, automatic thoughts that were highly critical of themselves. He proposed making these thoughts visible, examining them together with the person and testing how accurate they were.
Over the decades, cognitive and behavioural methods came together to form the current family of cognitive behavioural therapies. This family includes a range of protocols adapted to different difficulties.
The three main areas of CBT
CBT is not a single method. It brings together different approaches that can be described through three complementary areas. The importance given to each one varies according to the difficulty, the person’s goals and the protocol being used.
The behavioural approach
The behavioural approach looks at what a person does, avoids or repeats, as well as the consequences that keep these habits going. The work may involve gradually resuming an activity, approaching a feared situation in a planned way, developing new skills or testing a different behaviour. The aim is not to force the person, but to create experiences that allow new learning and restore a greater sense of choice.
The cognitive approach
The cognitive approach focuses on automatic thoughts, interpretations and beliefs that influence emotions and actions. The therapist helps the person identify them, examine the evidence that supports or qualifies them, and consider more balanced perspectives. This does not mean imposing positive thinking. It means gaining some distance from a conclusion that has become automatic.
The emotional approach
The emotional approach helps people recognise, name and better understand emotions and the physical sensations that accompany them. Depending on their needs, they may learn to experience an emotion without acting immediately, regulate its intensity, develop greater tolerance for discomfort or express what they feel in a more appropriate way. The goal is not to eliminate fear, sadness or anger, but to change how a person responds to them.
In practice, these three areas constantly overlap. Changing a behaviour can transform a belief, while understanding an emotion more clearly can make it possible to try a new way of acting.
How does CBT work?
Cognitive behavioural therapy is generally structured, collaborative and guided by goals agreed with the therapist. During the first appointments, the psychologist seeks to understand the difficulties, the situations in which they arise and what keeps them going. Together, you build a map of the problem.
This map may reveal a vicious cycle. For example, someone who fears being judged may avoid speaking in front of others. Avoidance provides relief in the short term, but prevents them from discovering that they could cope with the situation. The fear therefore remains intact and may even grow stronger. In CBT, the work may involve gradually approaching feared situations within a prepared framework and at a manageable pace.
A session will often include a review of the week, the selection of a topic and the practice of a tool. Treatment can be relatively brief, although longstanding or complex difficulties may require more time.
What tools are used?
There is no single exercise that sums up CBT. The psychologist selects tools according to the person’s needs and goals. They might suggest recording a situation, the thoughts that arose, the emotion felt and the response that followed. This can slow down a process that had previously seemed automatic.
Cognitive questioning can then be used to examine a thought: what evidence supports it or adds nuance? Could there be another explanation? The aim is to develop a more balanced and realistic view.
The behavioural dimension is equally important. The work may include gradual exposure to an avoided situation, returning to meaningful activities, problem-solving or experiments designed to test a belief. Exercises between sessions help put what has been learned into practice in everyday life.
What difficulties can CBT be used for?
CBT is used for many difficulties, including certain anxiety disorders, phobias, panic attacks, depression, obsessive-compulsive disorder, post-traumatic stress disorder and insomnia. Some techniques can also support people living with persistent pain.
Specialised forms of CBT may also be offered for certain eating disorders, such as bulimia nervosa, binge-eating disorder and, in some situations, anorexia nervosa. They may address regular eating patterns, concerns about weight and body image, difficult thoughts and emotional triggers. Eating disorders can involve significant physical risks, so treatment requires an appropriate assessment and may combine psychological, medical and nutritional support.
CBT can also help when someone finds it difficult to regulate or express anger. The work may focus on identifying triggers, thoughts that intensify the reaction, early physical warning signs and the behaviours that follow. Techniques for stepping back, communicating, solving problems or calming down can then help the person respond differently. Feeling angry is not in itself a problem; support primarily targets reactions that cause distress, damage relationships or put the person or others at risk.
This does not mean CBT automatically suits everyone or guarantees a result. The choice of approach depends on the person’s needs, clinical situation, preferences and resources, as well as the professional’s training. An assessment helps determine whether CBT is appropriate, whether it should be adapted or whether another form of support would be more suitable.
Does CBT only focus on the present?
CBT often starts with current problems because everyday life is where patterns can be observed and changed. However, it does not ignore the past. Earlier experiences may have contributed to deeply held beliefs such as “I am not good enough” or “I cannot trust anyone.” The therapist may explore where these beliefs came from when doing so helps explain what is happening today.
The approach also depends on the main difficulty. For traumatic memories, a professional may suggest trauma-focused CBT or consider another method.

CBT and EMDR are not necessarily competing approaches: they are based on different frameworks and can sometimes form part of broader treatment, depending on the therapist’s assessment.
