What Is Dialectical Behavior Therapy (DBT)?

Dialectical behavioural therapy (DBT) is an evidence-based therapy used to help people who struggle with many challenges in life, such as experiencing negative symptoms of mental conditions.

DBT is a therapy based on cognitive behavioural therapy (CBT), a psychotherapy that has proved to be significantly effective for those experiencing mental health difficulties.

CBT helps people identify goals and to overcome obstacles that may prevent these goals, as well as changing negative thinking patterns.

This is similar to DBT, which teaches critical skills to help individuals learn to manage their intense emotions, cope with distress, and cultivate healthy relationships. 

The D in DBT, dialectical, relates to two seemingly opposite viewpoints that can be true at the same time. The dialectical philosophy is that all things are connected, and change is constant and inevitable.

Dialectical strategies in DBT help the individual and their therapist to get unstuck from extreme positions, balancing out viewpoints, and view situations from multiple perspectives to reach a logical viewpoint.

The B in DBT, behavioural, means that DBT aims to change behaviours. During sessions, the DBT therapists learn to assess the situations and target behaviours that are relevant to the client’s goals, in order to figure out how to solve problems in their lives. 

DBT was developed by Marsha Linehan in the 1980s, initially developed to help people with suicidal thoughts, who often had a diagnosis of borderline personality disorder (BPD).

Individuals with BPD often suffer with the following symptoms:

  • Experience intense emotions

  • Have difficulties with their relationships

  • Their actions are very impulsive

  • Their thinking is very black and white

Thus, DBT was developed to help people with DBT manage these core symptoms by providing them with skills to reach their goals.

This way, people with DBT would know how to respond to challenging situations or manage relationships, so they can have a better quality of life overall. 

What Dialectical Behavioural Therapy can help with

Although DBT was developed with borderline personality disorder in mind, the techniques used in DBT can be effective for many of the following mental health conditions:

  • Major depressive disorder

  • Bipolar disorder

  • Generalised anxiety disorder (GAD)

  • Posttraumatic stress disorder (PTSD)

  • Attention deficit hyperactivity disorder (ADHD)

  • Eating disorders

  • Substance use disorders

People who feel as if their symptoms of their mental health condition are negatively impacting their quality of life may wish to seek help through DBT.

As well as helping individuals who have mental health conditions, DBT does not need to be limited to those with a diagnosed condition. People who experience any of the following may also benefit from DBT:

  • Those who struggle with intense emotions that they feel they cannot control.

  • Those who find it difficult to manage challenging situations.

  • Those who are experiencing negative consequences from encountering a lot of stress.

  • Those who struggle to maintain healthy relationships; may describe their relationships as unstable or like a rollercoaster. 

  • Those who experience negative and recurring thought patterns. 

  • Those who experience a lot of anger or get into a lot of conflicts with others.

  • Those who are experiencing negative consequences after a traumatic life event.

  • Those who may feel hopeless or empty.

  • Those who have tried other therapies and found they have not worked for them.

  • Those who feel as if their life is out of control. 

  • Those who believe their life is not fulfilling. 

  • Those who have suicidal thoughts or show self-injurious behaviours. 

Techniques of Dialectical Behavioural Therapy

The idea of DBT is to teach important skills and techniques through the four following components:


The premise of mindfulness is to teach the individual to be focused on the present moment and feel grounded. This technique is useful for those struggling with an unstable sense of self and/or those with difficulties being focused on the present.

This technique encourages the individual to pay attention to what is happening around them as well as inside, such as their thoughts and feelings. People completing mindfulness will learn to focus on their thoughts in a non-judgemental way and notice any negative thoughts which may arise.

After focusing on the present moment, the idea is that the automatic negative thoughts are not engaged with, resulting in feeling more settled.

This therefore teaches healthy coping skills for those struggling with negative thoughts. 

Emotion regulation

Learning to regulate emotions is a component of DBT which aims to help individuals be more comfortable and accepting of their own emotions.

This technique helps people to learn how to manage their difficult emotions which may arise so that the intense emotions they experience do not end up controlling the situation.

Through emotional regulation, people are taught that they may experience intense emotions, but they can choose how to react to them in a healthy way.

They can also learn to avoid situations that they know will trigger strong emotions, helping them to have more positive emotional experiences overall. 

Distress tolerance

As people experiencing issues with their mental health may encounter a lot of distress, the component of distress tolerance in DBT is important to learn how to manage upsetting situations.

This technique aims to help individuals to think about some of the healthy things they can do to manage their behaviour and emotions so that they do not act impulsively or risky, with potentially negative consequences.

This component can help with changing negative thought patterns. For instance, instead of thinking ‘It’s not fair’, they may ask themselves instead ‘Can I control the situation?’.

If they realise the situation cannot be controlled, then they learn to accept the situation for what it is.

This skill can help individuals prepare for intense emotions they may experience and use distraction techniques to help decrease the feelings of distress (e.g., listening to music or going for a walk).

Interpersonal effectiveness 

The final component of DBT is interpersonal effectiveness which aims to teach the individuals to communicate in healthy and respectable ways.

This teaches people to have more stable relationships with others through teaching them skills to assert themselves and put in good boundaries. This technique can also help build listening skills, conflict resolution skills, and help to build trust with others, which is a major issue for those with BDP especially.

Individuals can also learn to deal with challenging people in a healthy manner, acknowledge other’s thoughts and feelings, and learn to ask for what they need in a clear way. 

What Dialectical Behavioural Therapy sessions involve

There are different modes of treatment for DBT, which makes it different from other psychotherapies which may typically consist of just one mode of treatment. Each mode of treatment is intended to meet a specific function.

Individual psychotherapy

The function of one-to-one sessions with a therapist is to enhance the client’s motivation in order to apply learnt DBT skills to specific challenges and events in their lives.

These sessions are usually once a week and run for the duration of the therapy. Outside of the individual sessions, the clients will be asked to complete homework tasks.

An example of this being daily ‘diary cards’, which are used to track emotions, behaviours, and thoughts. 

Another goal of individual therapy is for the therapist to help the client structure their own lives, becoming managers of their lives.

The therapist does this by applying dialectical, validation, and problem-solving skills to enable the clients to learn to be their own manager of personal life challenges. 

Group skills training

Group skills training typically runs once a week for two-hour sessions, for the duration of the therapy.

Within these sessions, the group will learn skills in the four components of DBT: mindfulness, emotion regulation, distress tolerance, and interpersonal effectiveness.

As these are in a group setting, the clients have opportunities to interact with others and roleplay scenarios.

The group leaders will also assign homework to aid the clients in practising the skills they have been taught to their everyday life. 

Phone coaching

Another mode of treatment which is unusual for other therapies for mental health is phone coaching.

This means that the DBT therapist will be available to contact by phone for any incidents where the client may be faced with a challenging moment.

The therapist can give guidance on how to cope with a situation as it is happening. The overall goal of this contact is to coach the client on how to put their DBT skills into practice whenever required. 

Benefits of Dialectical Behavioural Therapy

Below are some of the positive changes that can arise as a result of completing DBT:

  • Individuals notice behavioural changes – they should be more able to identify when harmful behaviour patterns threaten to occur and should be able to replace these unhealthy behaviours with healthier ones.

  • The learning of new skill sets to deal with any challenging situation in life.

  • Cognitive changes which include the alteration of negative thoughts and beliefs about the self. 

  • The acceptance that some situations cannot be controlled but can be responded to in healthy ways.

  • Finding new, healthy methods of coping with distress. 

  • Being able to work collaboratively with others (especially during the group skills training). 

  • Being able to communicate more effectively with others, resulting in healthier relationships.


Linehan et al., (1991) conducted the first randomised controlled trial of the effectiveness of DBT on women with BPD.

It was found that after completion of DBT, participants showed significant improvements for chronically suicidal and self-injuring behaviours.

A more recent meta-analysis of the effectiveness of DBT on those with diagnosed BPD found that most studies reported significant reductions in suicidal ideation, self-injurious behaviours, depression, and anxiety (Bloom, Woodward, Susmaras, & Pantalone, 2012).

To conclude, DBT continues to be an effective psychotherapy for BDP, with one study finding that after a year of therapy, around 77% of the patients no longer met the criteria for the diagnosis of BPD (Stiflmayr et al., 2014). 

As well as being effective for BPD, there is also evidence that the skills learnt in DBT reduced depressive symptoms, improved affective control, and improved the mindfulness self-efficacy of those with bipolar disorder (Van Dijk, Jeffery, & Katz, 2013). 

DBT has also shown to help treat some of the symptoms associated with posttraumatic stress disorder (PTSD). It was found in a study that after completion of the therapy, individuals with PTSD were less likely to attempt suicide, self-harm, and had reduced feelings of shame, anxiety, and trauma-related guilt (Harned, Korslund, & Linehan, 2014).
