What Is Rational Emotive Behavior Therapy (REBT)?

What is REBT?

Rational emotive behaviour therapy (REBT) is a form of psychotherapy introduced by Albert Ellis in the 1950s. Alongside cognitive therapy created by Aaron Beck in 1976, REBT is thought to serve as the basis for the development of cognitive behavioural therapy (CBT).

Although REBT is considered under the umbrella of CBT, Ellis was thought of as the pioneer of CBT, being influential to Beck. 

This therapy was originally called rational therapy until it went on to include emotion and behaviour, taking into account these other fundamental components to the therapy.

REBT was developed as a departure from psychoanalysis, which was probably the most popular therapy at the time. It was thought that psychoanalysis was useful for making people feel better after getting everything off their chests.

However, Ellis questioned whether psychoanalysis actually helped people deal with the root cause of their problems or helped them feel better at all in the long-term. 

REBT is an action-oriented approach focused on helping people deal with their irrational beliefs and learn how to manage their emotions, thoughts, and behaviours in a healthier and more realistic way.

Ellis believed that humans are naturally goal-directed but they are also self-defeating and irrational. He believed that most people are not aware that many of their thoughts about themselves are irrational and negatively affect the way they behave in relationships and situations.

According to Ellis, these thoughts can result in people suffering negative emotions and engaging in self-destructive behaviours. 

Ultimately, REBT recognises that our cognition, emotions, and behaviour are all connected, all interacting and influencing each other.

In order to understand behaviour during situations, its essential to look at the beliefs that people hold about these situations and the emotions that arise as a result of those beliefs.

REBT is a short-term form of therapy which involves different types of techniques to challenge irrational beliefs and replace them with healthier, more productive ones.

REBT focuses mostly on the present to help someone understand how their perceptions of situations can cause emotional distress, which in turn, leads to unhealthy actions and behaviours that interfere with their life goals.

Once identified and understood and changed to more rational thoughts, this can help people to develop better relationships and approaches to situations and events. 

REBT can be particularly helpful for people living with a variety of issues, but especially those experiencing the following:

  • Depression

  • Anxiety 

  • Addictive behaviours

  • Phobias

  • Procrastination

  • Disorder eating habits

  • Sleep problems

  • Overwhelming feelings of anger, guilt, shame, or rage.

Core principles of REBT

A core concept of REBT is the ABC model. This model explains how, while we may blame external events for our unhappiness, it is our perception of these events that lies at the heart of psychological distress.

REBT is grounded in the idea that people generally want to do well in life and reach their goals.

However, sometimes irrational thoughts and feelings get in the way of these goals. These beliefs are thought to influence how an individual perceives circumstances and events. 

The ABC model is as follows:

Albert Ellis’ ABC Model in the Cognitive Behavioral Therapy

  • A – activating event – this is when something happens in the environment which triggers a negative reaction or response.

  • B – belief – this describes the thoughts about the triggering event or situation, usually irrational thoughts about the activating event.

  • C – consequence – this is the emotional response to the belief, which are usually distressing emotions that result from the irrational thoughts or beliefs. 

An example to illustrate this is to imagine a student who has the belief that they must be perfect in everything they do. The activating event could be that they fail to get the top grade in an exam at school.

The triggered beliefs about this activating event could result in irrational thoughts such as ‘I am a failure’, ‘I should feel ashamed’, or ‘I must do better’.

The consequences of these thoughts are that the student feels shame and guilt for not being perfectly competent in what they do, they may get upset and cry, or put unnecessary stress on themselves to work even harder next time to avoid feeling this way again. 

Holding irrational beliefs can make it almost impossible to respond to activating situations in a healthy way.

Albert Ellis’ ABC Model in the Cognitive Behavioral Therapy

For instance, an individual possessing rigid expectations of themselves, and others may find they frequently experience disappointment, regret, and anxiety. 

In REBT, people are helped to make the distinction between healthy negative feelings of concern and unhealthy feelings of anxiety. The healthy negative feelings may help during times of adversity, or someone may realise they cannot do anything about the situation and learnt to move on.

With anxiety, individuals tend to engage in self-defeating behaviour and have unhealthy attitudes that are rigid or extreme. REBT suggests that the attitudes that are brought to the aversive situation largely influence whether someone will feel unhealthy negative feelings.

With rigid attitudes to adversity such as using statements which use must, absolutely should, have to, and need to, an individual is more likely to experience extreme negative emotional consequences. 

REBT encourages people to realise that they have a choice in their emotions and to take accountability for their beliefs. The therapy will also encourage the use of language that is useful.

For instance, the student from the example could say ‘I made myself anxious about not getting the top grade. And if I can make myself anxious, then I can choose to no longer make myself anxious.’

Individuals are therefore turning away from blaming adversity for their disturbing emotions and realising that their own thoughts and beliefs made them feel these emotions. 

Techniques used in REBT

During REBT, the therapist will help the client to learn how to apply the ABC model to their daily life. They would work with the individual to change those beliefs and ultimately, their emotional response to situations. 

An important step in this process is recognising the underlying beliefs that lead to psychological distress. In many cases, these come as absolutes such as ‘I must’, ‘I should’, and ‘I can’t’ statements.

The therapist will usually discourage people from using these statements as they are unhelpful and irrational. 

Problem solving

Problem solving is intended to help the person address the A in the ABC model.

This involves addressing the activating event or adversity head on. Some common problem-solving methods include:

  • Teaching assertiveness

  • Learning social skills

  • Learning decision-making skills

  • Learning conflict resolution skills

Cognitive restructuring 

Cognitive restructuring focuses on helping the person to change their irrational beliefs, with techniques such as:

  • Disputing irrational beliefs

  • Reframing

  • Rationalising techniques

  • Guided imagery and visualisation

  • Using humour

  • Exposing yourself to the fear

Coping techniques 

Coping techniques are taught, to be learned in situations where the person cannot change the event or is struggling even though they are using rational thinking. Some coping techniques include: 

  • Relaxation 

  • Hypnosis

  • Meditation 

  • Mindfulness 

  • Breathing exercises


The therapist will usually teach their clients three forms of acceptance:

  • Unconditional self-acceptance – this is where the person recognises that they have good and bad points - they are flawed, but this doesn’t make them any less worthy than another person.

  • Unconditional other-acceptance – this is where the person recognises that some people won’t treat them fairly and there is no reason why everyone should treat them fairly. Although others will not treat them fairly, these people are no less worthy than any other person.

  • Unconditional life-acceptance – this is where the person recognises that life is not always going to go the way they want and there is no reason why it must go the way they want. They learn to accept that they may experience some unpleasant things in life, but life itself is never awful and is usually always bearable. 

Some REBT activities and exercises: 

Imagining the worst

Often, people will catastrophize situations, meaning that they use worst-case thinking. Catastrophizing is a common cognitive distortion where people will fear the uncertainty of potential negative events despite a lack of objective evidence to support this. 

REBT therapists can encourage clients to imagine the worst-case scenario when they are attempting to avoid thinking about it for fear of becoming more anxious. Utilising the worst-case scenario can help the client realise:

  • The worst-case scenario is unrealistic and therefore unlikely to happen.

  • Even if it did occur, the worst-case will probably still be tolerable.

  • If the worst does happen, they would still be able to manage the outcomes and prevent it from becoming catastrophic. 

Blown out of all proportion

This activity involves the use of imagery and humour to tackle irrational thoughts. The therapist will ask the client to imagine the thing they fear the most actually happening.

However, instead of encouraging them to visualise this realistically, the therapist will ask them to visualise it to an extreme level.

When their worst fears become exaggerated, they can become humorous. The idea is that laughing at blown-up fears will help the client get more control over them. 

Disputing irrational beliefs (DIBS)

DIBS is one of the most popular cognitive restructuring techniques in which the therapist questions the client’s beliefs head on, causing them to rethink them, or they could ask the client to imagine another point of view that they may not have considered before. 

Rather than the therapist being warm and supportive all the time, Ellis suggests that therapists should sometimes be blunt and honest to push people toward challenging their thoughts.

Disputing is a skill that can be learned in the long-term to help people to manage their emotional response and limiting some of their harmful beliefs. 

A DIBS activity may include writing down a core belief someone holds, then considering the following:

  • Are there any objective facts to support this belief? 

  • What proof is there that this belief is true/false? 

  • What is the worst outcome that could occur? 

Ellis recommended recording the irrational belief then writing several disputes to dispute this, so the person can visibly see there is more evidence that suggests their belief is false rather than true. 

As well as the work and activities completed in therapy sessions, the therapist is also likely to give work to do at home between sessions so that the individual can apply the skills they have learnt in sessions to their daily life.


Research suggests that REBT is effective at reducing irrational beliefs and changing behaviour. There is a wide range of applications for REBT.

In practice, REBT has been applied to various domains such as clinical psychology, education, organisational settings, and counselling. Since it is focused on education and taking action, it can be effective for a variety of situations and mental health conditions.

Many studies have shown the positive effects of this therapy, supporting REBT as a validated method to change negative responses and leading people to a happier life. 

Mental health

REBT is generally accepted as an effective type of therapy, finding it can help with conditions such as depression, anxiety, obsessive compulsive disorder, and disruptive behaviour.

The positive effects of REBT also appear to last even after therapy has ended. REBT was also found to be as effective as cognitive therapy and medication for the treatment of depression, with REBT being more effective than medication after 6 months (David, et al., 2008). 

Another study found that REBT group counselling was able to reduce the anxiety of school students compared to those given regular group counselling (Misdeni et al., 2019).

Ellis suggested that during group REBT approach, members are taught to detect each other and refute irrational beliefs. 

Burnout at school and work

REBT may be effective for reducing symptoms of burnout for students and has shown to continue to work even months after therapy concluded.

Group REBT has also shown to reduce job-related stress and burnout while increasing job satisfaction and commitment. 


REBT has become popular as a treatment option for athletes who are experiencing mental health issues. This may be because many athletes may have rigid beliefs that they need to be the best in their sport. 

REBT can be used to restore and maintain their mental health, helping them learn how to change their sometimes-unhelpful outlook and manage their emotions.

Although this therapy can improve an athlete’s performance, the goal of REBT in sports psychology is to care for their mental well-being first and foremost. Overall, REBT has shown to decrease irrational beliefs and reduce anxiety for athletes.

Alcohol and drug addiction

In 2010, up to 18% of drug and alcohol treatment centres in the United States were using REBT as their main treatment.

The idea of using this type of therapy is to facilitate sobriety and return to health and happiness by returning and/or lessening irrational thoughts and negative emotions that lead to addictive behaviours. 

REBT has been shown to work quite effectively for people with these addictions.

The therapy works to change the way these individuals think about situations, have more positive emotional reactions, and alter the way they act. 


There is some debate about the relationship between REBT and CBT. Some see REBT as a type of CBT while others argue they are very distinct approaches.

REBT is thought of as the original form of CBT and inspired Aaron Beck to develop his idea of cognitive therapy, which may be why the therapies have some overlaps and are based on similar principles.

Both approaches recognise that harmful thinking patterns and irrational thoughts can cause emotional suffering. REBT and CBT help people identify these unhelpful thoughts and then help to change them.

These therapies also maintain the understanding that our thoughts, feelings, and behaviours are all connected and influence each other. 

REBT is based on the theory that emotional disturbance such as shame, guilt, depression, and anxiety are largely self-constructed by a person’s thoughts and belief systems.

It seeks to address this self-defeated thinking. CBT works on looking at automatic thoughts that have been learned and become fixed during childhood and since become dysfunctional patterns, then seeks to undo these automatic thoughts. 

REBT is highly philosophical in the sense that it addresses the philosophic basis of emotional disturbance and teaches unconditional self-acceptance as its solution to low self-esteem.

The acceptance involves trying to avoid self-judgement and recognising that humans can and will make mistakes. CBT is more concrete in comparison and focuses on other people accepting them, rather than unconditional self-acceptance. CBT also focuses on reinforcing positive qualities to boost self-esteem.

This approach from CBT could have some potential pitfalls including lower self-esteem when the person does poorly or makes comparisons to others. 

These therapies have different views on anger. Whilst CBT views some anger as healthy and appropriate depending on the situation, REBT maintains that all anger has a commanding and condemning core.

REBT teaches people effective assertiveness and problem-solving when it comes to anger. Although CBT also teaches assertiveness, it fails to uproot the philosophic root of anger. 

The REBT therapist may use humour as a therapeutic tool which CBT may not. The REBT therapist may also be more confrontational with their client. A CBT therapist is directive but not as much as REBT, coming across as politer.

Finally, CBT is a more popular approach, has more research supporting it and it is shown to be effective for a wide range of disorders. REBT also has some research that supports it and has shown to be similarly effective, but not as much as CBT.

When deciding which therapy to choose, it may just depend on the individual’s preferred approach, what their specific problems are, and what they hope to gain from therapy. 

How to seek REBT

If you feel that REBT may be the right therapy for you, it is useful to begin by checking with your doctor for any recommendations of local therapists or mental health professionals who offer this approach. 

It can be helpful to take notes of specific things that you would like to address in therapy such as considering if there are any specific traits you look for in a therapist.

Try to look for a licensed mental health professional with training in REBT and in CBT if possible. It is important to find someone that you are comfortable with so do not be discouraged if you find that the first therapist you begin sessions with is not a good fit.

You may find that you need a few sessions to see if they are a good fit, but some people may also need to see a few therapists before they find the right one. 

What to expect

During your first therapy session, the therapist will likely discuss your goals and the activating event/s which prompted you to seek treatment, so it will be helpful to come prepared with what you want help with.

The therapist may also want to delve into the REBT techniques right away – this form is very active and focused, so the therapist is not likely to spend lots of time on casual conversation.

REBT is a relatively short-term treatment, with most people only requiring 10-20 sessions to accomplish their treatment goals.

It is important to stick to the treatment plan and consider if this is something you can commit to and make time for, since missing sessions can make it harder to overcome your problems. 

REBT is very action-orientated, and you will likely be set homework assignments to complete between sessions to allow you to practice what you have learned. It is important to complete the homework set by the therapist to gain as much as you can from the therapy.

REBT is not a passive process, and you will have to take responsibility for your own treatment. 

You will likely have to step outside of your comfort zone to get the benefits of this therapy. For some people, having the therapist dispute their thoughts can feel confrontational or aggressive.

Facing these irrational beliefs can be difficult for some as it may be not easy to accept that these beliefs are unhealthy. The process of changing these thoughts can be even more challenging as it may involve learning to let go of long-held beliefs.

It is therefore important to go into REBT with an open mind and be willing to try out new ways of thinking and different behaviours. The willingness to do this can impact how beneficial REBT is for you.
