Dialectical Behaviour Therapy, or DBT, is a structured talking therapy that can help manage emotions, improve relationships, and reduce harmful behaviours. Suppose you’re struggling with intense mood swings, self-harm, or unstable relationships. In that case, DBT therapy for borderline personality disorder (BPD) offers practical skills to help you get some control back and maybe even improve your quality of life.
Understanding Borderline Personality Disorder
Borderline Personality Disorder (BPD) is a complex mental health condition that affects how you feel, think, and relate to others. Recognising the main signs and how BPD impacts different areas of your life can help you seek the right support.
Key Symptoms and Diagnostic Criteria
BPD is most often recognised by intense mood swings, an unstable sense of self, and persistent feelings of emptiness. You may find your emotions shifting rapidly, sometimes without any clear trigger.
To receive a diagnosis, at least five symptoms from a defined set must usually be present. These can include impulsive behaviours, repeated self-harm, deep fears of abandonment, and difficulty trusting others.
Depression frequently occurs alongside BPD, with many people experiencing ongoing sadness or hopelessness.
Impulsivity can also lead to risky behaviours such as reckless spending, substance misuse, or binge eating. For this reason, it is important to undergo a thorough mental health assessment to gain a clear understanding of your symptoms and support needs.
Challenges in Emotion Regulation
One of the most noticeable features of BPD is trouble managing emotions. You may experience overwhelming feelings like anger, sadness, or anxiety that can last for hours or even days.
Sometimes, even small events seem huge and hard to handle. When emotions rise fast, it’s tough to calm down or see things clearly.
Poor regulation of emotions can lead to impulsivity. You might act on your feelings without thinking about the consequences, such as lashing out or making risky decisions you later regret. Learning skills to manage emotions is a significant part of treatment and can contribute to daily stability.
Impact on Relationships and Daily Life
BPD can make it harder to build and keep healthy relationships. You might be super sensitive to signs of rejection or abandonment, sometimes reacting with intense anger or panic.
This fear can lead to quickly changing feelings about people close to you. One moment, someone seems perfect; the next, you might feel totally let down. These patterns can cause stress at home, school, or work.
Daily life can get unpredictable if symptoms affect your decisions or interactions. Living with BPD is tough, but effective treatments can help you build more stable relationships and improve your quality of life.

What Is Dialectical Behaviour Therapy (DBT)?
DBT is a specialised form of psychotherapy designed to help people manage difficult emotions and challenging behaviours. It’s most commonly used in treating BPD.
Origins and Evolution of DBT
DBT was first developed in the late 1980s by Dr. Marsha Linehan, a psychologist who wanted to improve treatment for people experiencing chronic suicidality and BPD. She noticed that traditional cognitive behavioural therapy (CBT) didn’t fully address the intense emotional struggles faced by many of her clients.
DBT therefore integrates the practical strategies of CBT with principles of mindfulness and acceptance, offering a more compassionate and balanced approach. Over time, the therapy expanded to support people with other mental health challenges.
Today, DBT is a structured and evidence-based treatment recognised in many mental health settings. Programmes usually include individual therapy, group skills training, and sometimes telephone coaching for real-life support.
Evidence-Based and Clinical Trials
DBT is one of the most researched therapies for BPD, with lots of clinical trials backing it up. One study systematically reviewed randomised controlled trials (RCTs) assessing the effectiveness of DBT therapy for BPD.
Across 18 RCTs with 1,755 participants, DBT was found to reduce self-injurious behaviours, suicidal ideation, emergency visits, and hospitalisations, while also improving mood stability, impulsivity, and depressive symptoms. Both short-term and standard DBT showed benefits, with effects lasting up to 24 months post-treatment.
The authors concluded that while DBT is effective, more methodologically consistent research is needed to strengthen the evidence base.
Skills in DBT Therapy for Borderline Personality Disorder
This type of therapy teaches four main skill areas that help you better understand and manage intense emotions. With the help of mental health professionals, you can become more present, handle conflict, and cope in times of distress.
Mindfulness Techniques and Applications
Mindfulness is at the heart of DBT and helps you focus on the present moment. Practising mindfulness teaches you to notice your thoughts and feelings without judging yourself.
This skill lets you pause, observe what’s happening, and choose how to respond, rather than just reacting on autopilot.
You’ll likely learn both “what” skills (observe, describe, participate) and “how” skills (non-judgementally, one-mindfully, and effectively). Returning your attention to the present, whether you’re eating, having a conversation, or in a crisis, helps you slow down and think before acting.
Mindfulness can also help you access your “wise mind,” a balanced state that combines emotion and reason. With practice, you start to notice your own patterns and can get a little more control over automatic reactions.
Emotion Regulation Skills for BPD
These skills help you identify, understand, and change intense or unwanted emotions. You’ll learn to label your feelings, spot triggers, and break down how your emotions work. This makes it easier to manage mood swings and feel less overwhelmed.
Some important skills in this module include:
- Opposite Action: Doing the opposite of an unhelpful urge.
- Checking the Facts: Making sure your interpretations match reality.
- Building Positive Experiences: Increasing pleasant activities to help lift your mood.
These skills give you a toolkit for when emotions rise too quickly or too strongly. They help you become less vulnerable to mood shifts and support healthier decision-making.
Effectiveness Strategies
Interpersonal effectiveness teaches you to communicate your needs, set boundaries, and build healthier relationships. You learn to ask for what you want, say no, and keep your self-respect in social situations.
Many people with BPD struggle with unstable relationships, and these tools give you practical ways to improve communication.
Key strategies you may learn include:
- DEAR MAN: A step-by-step approach to asking for something or saying no politely.
- GIVE: Techniques for keeping relationships friendly and respectful.
- FAST: Tips to maintain your self-esteem while interacting with others.
With these strategies, you can feel more confident and reduce the risk of conflict or feeling misunderstood. Practising these skills helps you build relationships that are both supportive and respectful.
Distress Tolerance for Crisis Moments
Distress tolerance skills are for moments when you feel intense emotional pain and need to cope without making things worse. This module teaches you how to survive immediate crises and manage feelings like anger, sadness, or panic until they pass.
Some effective distress tolerance techniques include:
- TIP skills (Temperature, Intense exercise, Paced breathing, Paired muscle relaxation).
- Self-soothing using your senses (sight, sound, smell, taste, touch).
- Distraction and acceptance strategies (focusing attention elsewhere, using radical acceptance).
These skills offer practical ways to get through overwhelming moments without turning to harmful behaviours like self-harm or impulsive actions. The goal isn’t to erase pain instantly, but to ride out tough emotions safely until you regain control.

Practical Approaches and Coping Strategies
Treatment for BPD often means learning new ways to handle strong emotions, set limits in relationships, and take care of yourself. Using specific skills helps you gain more control and improve your daily life.
Self-Soothing Techniques
Self-soothing is about calming yourself during distress without turning to harmful behaviours. Deep breathing, listening to music, or doing something creative like drawing or writing can help. Sensory activities can ground you in the present.
Try making a self-soothing box with items that comfort you:
- A photo of someone you trust
- A soft object, like a stuffed animal
- A calming scent (like lavender)
- Relaxing music playlists
DBT encourages practising these techniques often, so they become second nature during hard moments. When emotions spike, self-soothing choices can help you feel safer and a bit more steady.
Developing Healthy Boundaries
Setting healthy boundaries teaches you how to protect your emotional well-being and avoid unhealthy patterns. You learn to say “no” without guilt, ask for space, and communicate your limits clearly.
This means figuring out what you can and can’t accept in relationships. Tips for building boundaries:
- Write down your limits in a notebook.
- Practise scripts such as “I’m not comfortable with that.”
- Notice when you feel drained after certain interactions.
Clear boundaries also help reduce impulsivity and emotional outbursts. Over time, these skills make it easier to care for yourself and respect others. Practising boundary-setting can ease anxiety and stop you from feeling overwhelmed in social situations.
Building Resilient Relationships
Healthy relationships support your recovery and wellbeing. DBT teaches tools for communication, empathy, and validation. You learn how to listen actively and respond thoughtfully, even when emotions run high.
Key strategies for relationship resilience include:
- Expressing your feelings using “I statements”, like “I feel anxious when…”
- Asking for clarification before reacting
- Taking breaks when you sense an argument is getting too heated
Strengthening these habits reduces misunderstandings and increases connection. Being honest and open helps relationships last longer and feel more secure. By focusing on small positive steps, you build trust and intimacy, which is a big part of DBT therapy for BPD.
Special Considerations and Co-Occurring Issues
Many people with BPD experience additional challenges, including substance use, medication needs, and difficulties with self-harm or impulsive acts. Addressing these areas often leads to improved treatment outcomes and greater stability in daily life.
Managing Substance Use and Substance Use Disorders
Substance use disorders show up a lot in people with BPD. Mood swings, intense emotions, or impulsivity can nudge you toward alcohol or drugs, which just makes everything harder to manage.
DBT includes strategies designed to tackle these issues. DBT therapists help you spot your triggers and build up new coping skills. You’ll work on swapping out harmful habits for healthier ones. Sessions usually focus on both BPD symptoms and substance use at the same time.
Treatment might involve both group therapy and one-to-one meetings, sometimes alongside other therapies for substance use.
Medication and Integrated Treatment
Medication is not a stand-alone solution for the treatment of borderline personality disorder, but it can be used to treat specific symptoms or co-occurring conditions such as depression and anxiety. Depending on your needs, doctors may prescribe antidepressants, mood stabilisers, or antipsychotics as part of a broader psychiatric care plan.
DBT is often most effective when paired with careful medication management. This combined approach can make it easier to manage severe mood swings, emotional distress, and other BPD symptoms.
Your DBT team may include other psychiatric professionals who monitor side effects, adjust prescriptions, and ensure that your treatment remains safe and effective. With an integrated plan, therapy and medication work together towards your long-term wellbeing and recovery goals.
Reducing Self-Harm and Impulsive Behaviours
Self-harm and impulsive acts, like dangerous spending, binge eating, or reckless driving, are big concerns for people with BPD. These behaviours can cause physical harm and pile on more stress.
DBT gives you tools to spot warning signs early and practice safer responses. Skills like distress tolerance and emotion regulation get a lot of attention in therapy. You’ll practise these methods both in sessions and in daily life, building up your ability to resist urges and try out less harmful actions.
Therapists also help you make safety plans and use crisis strategies. They offer frequent check-ins and between-session coaching that provide extra support when things get tough.
