CBT vs DBT: Understanding the Difference Between Two Powerful Therapies
In the world of mental health, it’s easy to get lost in the alphabet soup of therapy acronyms — CBT, DBT, ACT, EMDR. Two of the most well-known and widely practiced approaches are CBT (Cognitive Behavioural Therapy) and DBT (Dialectical Behaviour Therapy).
They share some similarities, but they’re not interchangeable. Knowing the difference can help you feel more confident when exploring therapy options, so you can find the approach that feels right for you.
What Is CBT?
Cognitive Behavioural Therapy (CBT) is one of the most widely researched and practiced forms of psychotherapy — and for good reason. It’s a structured, short-to-medium term, goal-oriented approach that examines the powerful connection between your thoughts, emotions, and behaviours.
The foundational idea behind CBT is simple but profound:
The way we think affects the way we feel, and the way we feel influences the way we act.
If your thoughts are unhelpful, distorted, or overly negative, they can intensify emotional distress and lead to unhelpful coping behaviours. By learning to identify, challenge, and replace these thought patterns, you can create positive changes in both mood and behaviour.
The Core Principles of CBT
- Identifying Unhelpful Thoughts
- The first step in CBT is becoming aware of your “automatic thoughts” — the quick, often subconscious mental reactions you have to situations.
- Example: You get an email from your boss asking to “chat,” and your mind jumps straight to “I’m in trouble” without considering other possibilities.
- The first step in CBT is becoming aware of your “automatic thoughts” — the quick, often subconscious mental reactions you have to situations.
- Challenging and Reframing Thoughts
- Once identified, these thoughts are examined for accuracy and helpfulness.
- You learn to ask: What evidence do I have for this belief? Is there another way to see the situation?
- Example: Reframing “I’ll fail no matter what” into “This will be challenging, but I can prepare and improve over time.”
- Once identified, these thoughts are examined for accuracy and helpfulness.
- Testing New Behaviours
- CBT uses behavioural experiments to help you see, firsthand, that new approaches can lead to different outcomes.
- This often involves gradually facing avoided situations, practicing new coping strategies, or experimenting with different responses.
- Example: If you fear speaking up in meetings, you might start by sharing one brief comment per session and observing how people respond.
- CBT uses behavioural experiments to help you see, firsthand, that new approaches can lead to different outcomes.
Why CBT Works
CBT is highly practical — you won’t just talk about your problems, you’ll work on them directly through exercises, worksheets, and “homework” between sessions. It’s an active collaboration between therapist and client, with the therapist acting as a coach rather than simply an advice-giver.
CBT is also time-limited for many people (often 8–20 sessions), which can make it appealing for those who want focused, results-driven support. Its structured nature helps track progress and maintain momentum.
Common Uses for CBT
Because CBT focuses on patterns that exist in nearly all human thinking, it’s been adapted to treat a wide range of conditions, including:
- Anxiety disorders (generalised anxiety, panic disorder, social anxiety)
- Depression and low mood
- Obsessive-Compulsive Disorder (OCD)
- Post-Traumatic Stress Disorder (PTSD)
- Phobias
- Insomnia
- Chronic pain management
- Eating disorders
A Real-Life Example
If someone has social anxiety, their automatic thought might be:
“Everyone will think I’m awkward.”
In CBT, they would:
- Identify that this is a thought, not a fact.
- Examine the evidence: Has anyone directly told me I’m awkward? Have I had social interactions that went well?
- Reframe the belief into something more balanced: “I might feel nervous, but most people are focused on themselves, not on judging me.”
- Test the new belief by attending a small social event and noting the outcome.
Over time, these small experiments help reduce fear, build confidence, and replace unhelpful assumptions with realistic perspectives.
What Is DBT?
Dialectical Behaviour Therapy (DBT) is a highly specialised, skills-based form of Cognitive Behavioural Therapy (CBT). Developed in the late 1980s by psychologist Dr. Marsha Linehan, DBT was originally created to support people experiencing extreme emotional dysregulation — often those living with Borderline Personality Disorder (BPD) — but has since proven useful for a wide range of mental health concerns.
What sets DBT apart is its unique combination of:
- The structure and problem-solving nature of CBT (targeting thought and behaviour patterns)
- Mindfulness practices inspired by Eastern philosophy
- The principle of dialectics — the ability to hold two seemingly opposite truths at the same time.
For example:
- “I am doing the best I can” and “I still need to work on making changes.”
- “I accept myself as I am” and “I also want to grow.”
This balance between acceptance and change is at the heart of DBT.
The Four Core Pillars of DBT
- Mindfulness – Staying Present in the Moment
- Mindfulness in DBT means becoming more aware of your thoughts, feelings, and surroundings without immediately reacting or judging yourself.
- This can help you notice emotional triggers before they spiral.
- Example: Instead of automatically sending an angry text, you might pause, take three deep breaths, and observe your feelings before deciding how to respond.
- Mindfulness in DBT means becoming more aware of your thoughts, feelings, and surroundings without immediately reacting or judging yourself.
- Distress Tolerance – Surviving Emotional Storms Without Harm
- These skills are designed for moments of acute crisis — times when emotions feel overwhelming and rational problem-solving isn’t yet possible.
- Distress tolerance tools can include self-soothing, distraction, or sensory grounding.
- Example: If you feel an urge to self-harm after a painful argument, you might use cold-water immersion (holding an ice cube or splashing your face with cold water) to physically reset your nervous system.
- These skills are designed for moments of acute crisis — times when emotions feel overwhelming and rational problem-solving isn’t yet possible.
- Emotion Regulation – Understanding and Adjusting Emotional Patterns
- DBT teaches you how to identify your emotions, understand what triggers them, and take proactive steps to reduce vulnerability to intense mood swings.
- Example: Recognising that poor sleep and skipping meals make you more likely to overreact, you plan ahead to maintain balanced routines.
- DBT teaches you how to identify your emotions, understand what triggers them, and take proactive steps to reduce vulnerability to intense mood swings.
- Interpersonal Effectiveness – Building Healthy, Respectful Relationships
- This skill set helps you communicate needs, set boundaries, and handle conflict without damaging relationships or self-respect.
- Example: Instead of ghosting a friend after feeling hurt, you might use the DEAR MAN skill (Describe, Express, Assert, Reinforce, Mindful, Appear confident, Negotiate) to address the issue calmly.
- This skill set helps you communicate needs, set boundaries, and handle conflict without damaging relationships or self-respect.
Who Can Benefit from DBT?
Although DBT is still most commonly associated with BPD treatment, it has been successfully adapted for:
- Trauma and complex PTSD
- Eating disorders (especially binge eating and bulimia)
- Substance use recovery
- Bipolar disorder
- Self-harming behaviours
- Suicidal thoughts or feelings
- Generalised emotional intensity that impacts daily life and relationships
A Real-Life Example
Let’s say you have a fight with a partner. In the past, you might have yelled, sent angry messages, or engaged in self-destructive coping behaviours. In DBT, you’d learn to:
- Pause and recognise the emotional wave rising (Mindfulness)
- Ground yourself with a skill like paced breathing or holding ice (Distress Tolerance)
- Label the emotion (“I’m feeling intense anger mixed with fear”) and check its intensity (Emotion Regulation)
- Communicate clearly with your partner about your needs once the emotion has passed (Interpersonal Effectiveness)
Over time, these skills help reduce the number of emotional “fires” you have to put out, while improving your sense of control and connection.
Key Similarities Between CBT and DBT
Although CBT (Cognitive Behavioural Therapy) and DBT (Dialectical Behaviour Therapy) are different in focus, they share a strong foundation. Both are grounded in evidence-based practice, which means they’re backed by decades of research showing real, measurable improvements for a variety of mental health concerns — from anxiety and depression to PTSD and personality disorders.
Here’s what they have in common:
- Evidence-Based
- Both CBT and DBT have been tested in clinical trials and found effective for a wide range of issues.
- Their techniques are adaptable to individuals, groups, and even online therapy formats.
- Both CBT and DBT have been tested in clinical trials and found effective for a wide range of issues.
- Skills-Focused
- These therapies don’t just focus on talking about your problems — they actively teach you tools you can use outside of therapy.
- Examples include learning how to pause before reacting, challenging unhelpful thoughts, or creating a plan for overwhelming situations.
- These therapies don’t just focus on talking about your problems — they actively teach you tools you can use outside of therapy.
- Structured Sessions
- Unlike some open-ended talk therapies, CBT and DBT use clear session agendas and treatment plans.
- You’ll know what skills you’re working on and why, which can make progress feel more tangible.
- Unlike some open-ended talk therapies, CBT and DBT use clear session agendas and treatment plans.
- Collaborative Approach
- In both models, you’re not a passive recipient. The therapist works alongside you as a partner in problem-solving, not as someone with all the answers telling you what to do.

Bottom line: Whether you start with CBT or DBT, you can expect a structured, skill-building, and collaborative experience that’s designed to create lasting change.
The Big Differences
While CBT’s primary goal is to help you change your thoughts so you can change your behaviour, DBT recognises that sometimes the situation itself is so painful, it’s not just about “thinking differently.” Instead, DBT adds an acceptance component — helping you hold space for your reality while still making changes that move you forward.
Below, we’ll break down some of the major differences with more detail and examples.
1. Emotional Intensity
- CBT:
- Works best when your emotions are distressing but still within a range that feels manageable.
- For example, someone with moderate social anxiety might use CBT to challenge beliefs like, “If I speak up, everyone will think I’m stupid” and replace them with more balanced thoughts.
- The focus is on shifting internal narratives so emotions naturally follow suit.
- Works best when your emotions are distressing but still within a range that feels manageable.
- DBT:
- Created specifically for people who feel emotions as overwhelming “tidal waves” — so strong that they take over thoughts, behaviours, and relationships.
- For example, someone who goes from calm to extreme anger in seconds, or from feeling okay to hopeless after a minor conflict, may benefit from DBT’s step-by-step regulation skills.
- The priority here is stabilisation: finding ways to stay afloat even when the emotional waters are rough.
- Created specifically for people who feel emotions as overwhelming “tidal waves” — so strong that they take over thoughts, behaviours, and relationships.
2. Skill Sets
- CBT:
- Primary skills include:
- Thought Restructuring: Challenging cognitive distortions like catastrophising or black-and-white thinking.
- Behavioural Experiments: Testing out new behaviours to see if fears or beliefs hold true.
- Problem-Solving: Breaking down overwhelming challenges into small, actionable steps.
- Thought Restructuring: Challenging cognitive distortions like catastrophising or black-and-white thinking.
- Example: Someone who avoids applying for jobs due to fear of rejection might use CBT to gradually challenge that belief and take small action steps.
- Primary skills include:
- DBT:
- Combines change-oriented strategies with acceptance practices.
- Core skill modules include:
- Mindfulness: Learning to stay present and observe thoughts and emotions without judgement.
- Distress Tolerance: Surviving emotional crises without making the situation worse.
- Emotion Regulation: Identifying, understanding, and adjusting emotional responses.
- Interpersonal Effectiveness: Communicating needs clearly while maintaining relationships and self-respect.
- Mindfulness: Learning to stay present and observe thoughts and emotions without judgement.
- Example: Someone prone to impulsive decisions during intense sadness might use distress tolerance techniques — like self-soothing or grounding — until the emotion subsides.
- Combines change-oriented strategies with acceptance practices.
3. Focus on Relationships
- CBT:
- While CBT can address relationship challenges, its focus is typically on how your thoughts influence your emotions and behaviours in general.
- Relationship work in CBT might involve identifying unhelpful thinking patterns about others (“They must hate me if they didn’t reply right away”) and testing them for accuracy.
- While CBT can address relationship challenges, its focus is typically on how your thoughts influence your emotions and behaviours in general.
- DBT:
- Puts a significant emphasis on relationships, recognising that emotional dysregulation often leads to conflicts, ruptures, or difficulties in maintaining connections.
- DBT’s interpersonal effectiveness module teaches practical communication tools, boundary setting, and conflict resolution.
- Example: Learning how to say “no” without guilt, or how to ask for support without escalating into an argument.
- Puts a significant emphasis on relationships, recognising that emotional dysregulation often leads to conflicts, ruptures, or difficulties in maintaining connections.
How to Know Which Might Be Right for You
You might lean toward CBT if:
- You want to target specific unhelpful thoughts and behaviours
- You feel emotionally steady enough to focus on change
- You like structured homework and measurable progress
You might lean toward DBT if:
- Your emotions often feel overwhelming or out of control
- You struggle with self-destructive behaviours in times of distress
- You want tools for both acceptance and change
Why Understanding the Difference Matters
Choosing between CBT and DBT isn’t about picking the “better” therapy — it’s about finding the right fit for your needs right now. You might even use both over the course of your healing journey.
Think of it like choosing tools: CBT might be like a sharp chisel, perfect for reshaping thoughts with precision, while DBT is like a full toolbox — especially handy when emotions spill over into every part of your life.
Whether you’re drawn to CBT’s targeted thought work or DBT’s emotional skill-building, both approaches offer pathways to more balanced thinking, healthier behaviours, and better emotional regulation.
