Key Takeaways
Dialectical Behaviour Therapy (DBT)
Dialectical Behaviour Therapy, or DBT, is a type of talk therapy that helps people manage overwhelming emotions and improve their relationships. It was originally developed by psychologist Marsha Linehan in the late 1980s and combines two ideas that might seem opposite: accepting yourself as you are, while also working toward meaningful change. The word "dialectical" refers to balancing these two forces at once.
DBT is rooted in cognitive-behavioural principles and incorporates mindfulness concepts drawn from Buddhist practices. It has a strong evidence base, particularly for borderline personality disorder, and is also studied for mood disorders, eating disorders, and PTSD.
What Makes DBT Different from Other Therapies
Many therapy approaches ask you to change the way you think or behave. DBT does something subtly different — it asks you to do both simultaneously: accept where you are and commit to growth. This balance is what sets it apart.
The therapy was developed by Dr. Marsha Linehan, who recognised that some people experience emotions far more intensely than others — and that telling them to simply "think differently" often felt dismissive. DBT was built around the idea that valid emotional pain deserves acknowledgement before change can meaningfully happen.
If you are exploring different therapeutic approaches, it is worth understanding how DBT compares to others. For instance, Acceptance and Commitment Therapy (ACT) also emphasises acceptance but organises its framework around personal values rather than skill sets. Meanwhile, Cognitive Behavioural Therapy (CBT) focuses more directly on restructuring unhelpful thoughts.
Who DBT Was Designed For
DBT was originally created to support people diagnosed with borderline personality disorder (BPD), a condition characterised by intense emotional experiences and difficulties with relationships and self-image. Over time, its use has expanded to include other conditions where emotional dysregulation plays a central role. However, DBT is not a universal fit — a mental health professional should always assess whether it is appropriate for an individual's specific needs and history.
The Four Core Skill Modules
DBT is organised around four interconnected skill areas. These are typically taught in a structured group setting alongside individual therapy sessions.
- Mindfulness: The foundation of all DBT skills. Mindfulness here means learning to observe your thoughts and feelings without immediately reacting to them. It is about building awareness rather than achieving calm. Explore mindfulness practices that support mood for related techniques.
- Distress Tolerance: These skills help you get through a crisis without making things worse. Rather than eliminating painful feelings, distress tolerance strategies help you ride out intense moments safely.
- Emotion Regulation: This module focuses on understanding why emotions arise and how to reduce their intensity over time. It includes identifying triggers, improving sleep and nutrition habits, and building positive experiences deliberately.
- Interpersonal Effectiveness: These are practical communication tools — how to ask for what you need, say no without damaging a relationship, and maintain self-respect in difficult conversations.

Reduction in self-harm incidents
A widely cited meta-analysis found approximately a 50% reduction in self-harm behaviours among people with BPD who completed DBT programmes, compared to control conditions.

Core DBT skill modules
Standard DBT training covers four structured modules — mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness — typically taught over 6–12 months.
1980s
Year DBT was developed
DBT was developed by psychologist Dr. Marsha Linehan at the University of Washington, originally designed to treat chronically suicidal individuals with borderline personality disorder.
What DBT Looks Like in Practice
A full DBT programme typically has three components working together: weekly individual therapy sessions, a weekly skills-training group (which functions more like a class than group therapy), and access to phone coaching for real-time support between appointments.
The individual therapy sessions focus on your personal goals and help you apply skills to situations arising in your own life. The group is where the skills themselves are taught — usually over a rotation of the four modules across several months.
If a full programme is not accessible to you, shorter skills-focused DBT workshops and adapted individual-only formats exist, though these differ from the complete model. A licensed mental health professional is the right person to advise on what is available and suitable.

Building Emotional Skills Over Time
DBT is not a quick fix — and that honesty is part of what makes it credible. Developing new emotional habits takes consistent practice, usually over many months. The skills are designed to be practised between sessions, not just discussed inside them.
Many people find that DBT skills complement broader efforts to strengthen emotional resilience. Our complete guide to emotional resilience covers the wider picture of how this capacity develops across a lifetime.
“You can't think your way out of pain that was felt into existence. DBT acknowledges that some people feel more, and teaches them to work with that intensity rather than against it.”
— Marsha Linehan, Psychologist and creator of Dialectical Behaviour Therapy, University of Washington
If you are curious whether DBT could be right for you, speaking with a qualified mental health professional is the most important first step. They can assess your needs, explain what is available locally, and help you weigh your options — including how DBT fits alongside other approaches discussed in our overview of therapy options.

Preparing for Your First DBT Conversation
If you are thinking about exploring DBT, it helps to go into an initial consultation with a clear sense of what you are experiencing — not a diagnosis, but a description of the patterns or moments that feel most difficult. Being specific about what is not working in your day-to-day life gives a therapist the clearest picture of whether DBT's skills framework is likely to be a good fit for you.
