Understanding Dialectical Behaviour Therapy (DBT)

Why DBT is one of the most powerful tools available for complex, long-standing mental health struggles.

Dialectical Behaviour Therapy, or DBT, was originally developed in the late 1980s by American psychologist Dr Marsha Linehan. It was designed specifically for people whose emotional experiences were so intense, so rapidly shifting, and so difficult to manage that conventional talking therapies weren't enough, and specifically for people suffering with BPD. Since then, it has grown into one of the most widely researched and evidence-based approaches in modern mental health care.

But what exactly is it? And why does it work so well for complex and chronic mental health difficulties?

The "dialectic" at the heart of DBT

The word dialectical refers to the integration of opposites, and this sits at the very core of the therapy. The central dialectic in DBT is the tension between acceptance and change.

This might sound simple, but for many people in psychological distress it feels genuinely impossible. On one hand, they have often been told (explicitly or implicitly) that their feelings are wrong, excessive, or too much. On the other, they are desperate to change and may be highly self-critical about why they haven't managed to yet.

DBT holds both truths at once: you are doing the best you can, and you can do better.

"DBT doesn't ask you to fix yourself, or to pretend things are fine. It asks you to learn how to navigate your own inner world with more steadiness and choice, one skill at a time."

This dialectical stance, which is radical acceptance alongside genuine skill-building, creates a therapeutic relationship that feels both validating and hopeful. For many clients, it is the first time they have experienced both simultaneously.

Who does DBT help most?

DBT was originally developed for borderline personality disorder (BPD), and the research evidence for that population remains exceptionally strong. But over the decades, it has proved effective across a much wider range of presentations.

It tends to be particularly powerful for anyone who experiences emotional intensity as a central feature of their difficulties - where feelings arrive fast, peak high, and take a long time to settle. This emotional sensitivity is not a character flaw; it is often rooted in early experiences and, frequently, in neurodivergence.

• Borderline Personality Disorder ( BPD/EUPD)

• ADHD with emotional dysregulation

• Self harm and suicidal ideation

• Substance use and addictive behaviours

• Eating disorders

• Trauma and CPTSD

For many of these individuals, a purely insight-focused therapy which involves talking about the past, and exploring patterns, isn't enough on its own. They need practical skills to use in the heat of the moment, alongside the therapeutic relationship and deeper processing work.

DBT and emotional sensitivity: reframing the narrative

One of the most important contributions DBT makes is how it invites us to understand emotional intensity. Rather than framing it as dysfunction, DBT describes emotional sensitivity as a biological predisposition that has been shaped by an invalidating environment.

"Many people who come to DBT have spent years believing that their emotional responses are wrong. DBT reframes this entirely: you were never broken. You were simply never taught the skills you needed."

This is a profoundly different message to the one many clients have internalised. And it shifts the work from self critcism to self-understanding, a far more sustainable foundation for lasting change.

There is also a meaningful overlap between emotional dysregulation and ADHD. Rejection sensitive dysphoria, emotional flooding, and difficulty returning to baseline are features that appear across both. DBT's skills are often exceptionally well-suited to neurodivergent individuals, particularly when the therapy is adapted to account for how ADHD affects the way we learn, process, and practice

How DBT works in practice

Traditional DBT is delivered as a comprehensive programme combining individual therapy, a weekly skills training group, phone coaching between sessions, and therapist consultation. This intensity reflects the seriousness of the presentations it was designed for.

However, these days DBT has evolved considerably. At Door94 we offer DBT-informed individual therapy, where a DBT qualified therapist weaves DBT skills, principles, and strategies into one-to-one work. This way of working is increasingly more common and also highly effective. It offers much of the therapeutic value of the full programme in a format that is accessible to more people.

"Jacqui is a great listener and takes time to understand the situation, and adapts our sessions dependant on what she feels would be beneficial for me, and her judgement has never failed." Emily, DBT Informed Therapy client.

What to expect from DBT work

DBT is active and skills-based, it is not a passive process.

Clients are asked to practise between sessions, to complete diary cards tracking their emotions and urges, and to apply skills in real situations. This is challenging, and that is by design.

Progress in DBT looks like:

A moment's pause before reacting where there was none before.

A difficult conversation navigated without the relationship rupturing.

An overwhelming feeling that passes without becoming a crisis.

Small changes, consistently practised, add up to something genuinely transformative.

The research consistently shows that DBT reduces self-harm, suicidal ideation, hospitalisations, and emotional suffering - often dramatically, over the course of treatment. For many clients, it is the first approach that has produced tangible, lasting results.

Is DBT right for you?

DBT is not the right approach for everyone, and a good therapist will always assess carefully whether it is a good fit. But if you recognise yourself in any of the following, it may well be worth exploring:

• You feel emotions intensely and find them difficult to regulate.

• Relationships are important to you but often feel complicated or painful.

• You have found it hard to sustain changes you have worked hard for.

• You have struggled with self-harm, crisis episodes, or feeling chronically overwhelmed.

• You have been through therapy before and felt that something was missing.

If any of this feels familiar, DBT could be exactly what you have been looking for.
