Dialectical Behaviour Therapy (DBT)

Dialectical behaviour therapy (DBT) is a comprehensive, evidence-based cognitive behavioural psychotherapy originally developed by Dr Marsha M. Linehan to treat chronically suicidal people diagnosed with borderline personality disorder (BPD). At its core lies a dialectical philosophy that brings together acceptance and change. DBT aims to help people both accept themselves and their current situation without judgement and change their behaviour in order to lead a healthier, more meaningful life. The therapy has four main components: individual therapy, a skills training group, telephone coaching and a therapist consultation team. Skills training is organised into four modules: mindfulness, emotion regulation, distress tolerance and interpersonal effectiveness. Although originally developed for BPD, DBT has since proved effective for other groups, including people with eating disorders, substance use disorders, post-traumatic stress disorder and adolescents with emotion regulation difficulties. This article examines in detail the theoretical foundations of DBT, its structural components, core skills modules, areas of application and the evidence for its effectiveness in the scientific literature.

Dialectical behaviour therapy (DBT)

1. Introduction

Treating people with multiple, complex problems and serious difficulties with emotion regulation and impulse control has always been a major challenge in psychotherapy. In the late 1980s, Dr Marsha M. Linehan and her team observed that standard cognitive behavioural therapy (CBT) was not enough for chronically suicidal people with borderline personality disorder. The relentless focus of standard CBT on change and problem solving left these clients feeling constantly criticised and invalidated. This led Linehan to develop a new model that included both behavioural change and radical acceptance (Linehan, 1993a).

DBT takes its name from the philosophy at its heart: dialectics. A dialectical worldview holds that reality is made up of opposing poles that are in constant tension and synthesis. The central dialectic in DBT is the tension between “acceptance” and “change”. The therapy teaches clients, on the one hand, to radically accept their current reality and emotional pain and, on the other, to acquire the behavioural skills needed to reduce that pain and build a more fulfilling life. This article aims to analyse DBT in depth within a scientific framework, from its philosophical roots to its structure, core interventions, skills modules and clinical effectiveness.

2. Philosophical and theoretical foundations

DBT is an integrative model drawing on three main theoretical approaches: dialectical philosophy, behaviour therapy and Zen Buddhism (mindfulness).

2.1. Dialectical philosophy. Dialectics is a worldview holding that everything is interconnected and constantly changing, and that a new synthesis emerges from the conflict of opposites (thesis and antithesis). DBT integrates this philosophy into therapy. The therapist accepts that the client is suffering and feels helpless (acceptance) and also believes the client needs to learn new skills and make an effort to escape that suffering (change). Finding the balance between these two poles is one of the core aims of therapy. “Both… and…” thinking challenges rigid, polarised “either… or…” patterns (Swenson, 2016).

2.2. Behaviour therapy. By origin, DBT is a cognitive behavioural therapy. It adopts the basic principles of behaviourism: unwanted behaviours are learned, and new, more functional behaviours can be taught. Using these principles, DBT actively employs techniques such as problem solving, behavioural analysis (chain analysis), reinforcement, exposure and operant conditioning. Chain analysis in particular, which examines the triggers before a problem behaviour, the behaviour itself and its consequences, is one of DBT’s core intervention tools (Linehan, 1993a).

2.3. Zen Buddhism and mindfulness. The most important element of DBT’s “acceptance” side is the practice of mindfulness, borrowed from Zen philosophy. Linehan noticed that people with BPD tend either to avoid intense, painful emotions or to be swept away by them. Mindfulness teaches people to experience the present moment just as it is, without judgement, observing thoughts, feelings and bodily sensations as an observer would. This allows them to respond wisely and in line with their values rather than reactively. DBT’s concept of “Wise Mind” describes this state of inner wisdom as a synthesis of the reasonable mind and the emotional mind.

3. Structure and components of DBT

Comprehensive (standard) DBT consists of four complementary components designed to maximise the effectiveness of treatment.

3.1. Individual therapy. Weekly individual sessions of about 50–60 minutes form the centre of therapy. Their main purpose is to sustain the client’s motivation and help them apply the skills learned in the group to specific problems in daily life. The therapist reviews the week using the “diary card” the client fills in between sessions, which tracks target behaviours (such as substance use), emotions and the skills used. In individual therapy, targets are addressed in a strict hierarchy:

1. Life-threatening behaviours: the highest-priority targets, such as suicidal behaviour and self-injury.
2. Therapy-interfering behaviours: behaviours that undermine therapy, such as missing appointments, not completing assignments or not cooperating with the therapist.
3. Quality-of-life-interfering behaviours: behaviours that lower overall quality of life, such as substance use, risky sexual behaviour, or problems at work or in relationships.
4. Skills acquisition: learning and strengthening new, more functional behavioural skills.

3.2. Skills training group. These weekly group sessions of about 2–2.5 hours take the form of a class or psychoeducational workshop. Their aim is for clients to learn DBT’s four core skills modules systematically. Group leaders (usually two therapists) teach the skills, give examples and set homework, and clients share their experiences of applying the skills in their own lives. A full skills cycle usually takes six months, and comprehensive DBT programmes usually cover two full cycles, about a year (Linehan, 1993b).

3.3. Telephone coaching. One of DBT’s most distinctive components, telephone coaching allows clients to reach their individual therapist at times of crisis. The aim is not to hold an extra therapy session but to help the client remember and apply the skills they have learned in the crisis they are facing. This “in-the-moment coaching” helps skills generalise to real-life situations and increases the client’s confidence in their ability to solve problems.

3.4. Therapist consultation team. DBT is a demanding and intensive model for therapists, so all therapists practising DBT must attend weekly consultation team meetings. The team functions as “therapy for the therapists”: therapists discuss their cases, look for ways to deal with difficulties, support one another and make sure they remain faithful to the DBT model. This component is vital for preventing therapist burnout and keeping the quality of treatment high.

4. DBT skills modules

DBT teaches skills in four main areas to help clients build a more functional life.

4.1. Mindfulness. This module underpins all the other skills. Its aim is to increase the ability to control attention and experience the present moment without judgement.

• “What” skills: observe (notice using the senses alone), describe (put words to what is observed) and participate (enter fully into the moment).
• “How” skills: non-judgementally (without labelling things good or bad), one-mindfully (focusing on one thing at a time) and effectively (doing what works).

4.2. Emotion regulation. This module helps clients understand their emotions, reduce emotional suffering and manage their emotional reactions.

• Understanding and naming emotions: understanding what emotions are for and naming specific emotions.
• Check the facts: assessing whether an emotion fits the current situation.
• Opposite action: doing the opposite of the unhelpful action the emotion urges (for example, approaching instead of avoiding when afraid).
• Reducing emotional vulnerability (PLEASE skills): treat Physical iLlness, balanced Eating, Avoid mood-altering substances, balanced Sleep and Exercise.

4.3. Distress tolerance. This module teaches skills for getting through intensely painful crises that cannot be changed immediately without making things worse. The focus is on “surviving the moment”.

• Crisis survival skills (TIPP): aim to reduce intense emotional arousal quickly by changing the body’s physiology: Temperature, Intense exercise, Paced breathing and Paired muscle relaxation, practised with guidance from the therapist.
• Distraction (ACCEPTS skills): shifting the focus of attention away from a painful emotion.
• Self-soothing: using the five senses (sight, hearing, smell, taste, touch) to comfort oneself.
• Radical acceptance: the skill of fully and completely accepting a reality that cannot be changed, without approving of it or liking it.

4.4. Interpersonal effectiveness. This module helps clients express their needs effectively while maintaining both their relationships and their self-respect.

• DEAR MAN skills: for asking for something or saying no: Describe, Express, Assert, Reinforce, stay Mindful, Appear confident, Negotiate.
• GIVE skills: focus on keeping or improving the relationship: be Gentle, act Interested, Validate, use an Easy manner.
• FAST skills: focus on keeping self-respect: be Fair, no unnecessary Apologies, Stick to values, be Truthful.

5. Applications and effectiveness

Numerous randomised controlled trials of DBT have established it as a “gold standard” treatment, particularly for borderline personality disorder (Kliem et al., 2010). Research shows that, compared with standard treatment, DBT significantly reduces suicide attempts, self-injury, hospital admissions and dropout from therapy. Marked improvements have also been reported in anger control, social adjustment and overall functioning (Stoffers et al., 2012).

Although originally designed for BPD, the emotion regulation and distress tolerance mechanisms at the core of DBT have made it adaptable to many other psychiatric disorders. Other areas in which DBT and DBT-based programmes have been studied include:

• substance use disorders, especially when they occur with BPD
• eating disorders, such as binge eating disorder and bulimia nervosa
• post-traumatic stress disorder, especially in people with a history of complex trauma
• treatment-resistant depression
• adolescents with emotion regulation difficulties (DBT-A)

These adaptations show that DBT offers a flexible and powerful therapeutic framework.

6. Conclusion

Thanks to Marsha Linehan’s pioneering work, dialectical behaviour therapy has brought hope and effective treatment to one of the groups considered hardest to treat. The dialectical balance of acceptance and change at its centre offers clients the compassion to accept themselves as they are, while giving them concrete tools to reduce their suffering and build “a life worth living”. Combining the rigour of behavioural science with the wisdom of Zen philosophy, this integrative model, with its multiple components and structured skills training, is regarded as one of the major achievements of modern psychotherapy. Its scientifically supported effectiveness makes DBT a valuable intervention not only for borderline personality disorder but for many psychiatric conditions in which emotion dysregulation is central.
