DBT vs. CBT for Borderline Personality Disorder (BPD): Which Therapy Is More Effective?

“I feel like I’m too much and also not enough.” Clients with Borderline Personality Disorder (BPD) often describe this confusing duality.  For young adults struggling with BPD, life transitions may be overwhelming. Leaving for college, forming new friendships, and moving away from home may feel unmanageable and even painful. Luckily, symptoms of BPD can improve with the right therapy, medication, and support.

At The Dorm, we understand the importance of finding the right help for treating BPD for young adults. Cognitive Behavioral Therapy (CBT) and Dialectical Behavioral Therapy (DBT) are two modalities often used in talk therapy and for people with BPD. We spoke with Nancy Tobias-Cohen, LCSW, a Clinical Supervisor and expert in DBT, to explore the role of each of these modalities and what someone should expect when seeking treatment.

What to Know: CBT vs. DBT

The Dorm: Thank you for taking the time to speak on this important subject, Nancy. What do you see as the main differences between CBT and DBT in terms of treating BPD?

Nancy Tobias-Cohen, LCSW: CBT is a widely used modality grounded in understanding the relationship between thoughts, beliefs and actions. Many people with BPD experience black and white thinking and CBT can be a helpful way to find a more balanced perspective. For example, if a client says, “All of my friends hate me!”, using CBT, a clinician and client may explore the thought process that led to that conclusion.

In contrast, DBT focuses on building practical skills to help clients regulate emotions and communicate more effectively. It is structured around four core modules: 

• Mindfulness
• Interpersonal Effectiveness
• Emotional Regulation
• Distress Tolerance

Using the same example with a DBT framework, I would guide them to use a skill called Check the Facts to assess whether their emotional response fits the reality of the situation. Then they could choose a tool, such as Opposite Action, to respond using a healthy coping mechanism. Rather than analyzing thoughts, DBT emphasizes using tools to respond effectively in the moment.

What does it actually look like to do CBT versus DBT?

CBT often involves worksheets and structured exercises that help clients identify thinking patterns and understand how those patterns influence behavior. Once clients identify a thought pattern, we work to shift and reframe the reasoning that contributes to harmful behaviors.

DBT is skills-based and typically includes individual therapy/coaching and a group to learn alongside peers. Clients review a structured curriculum, practice new skills between sessions, and track their progress together in our DBT group here at The Dorm. Working individually and in a group reinforces learning the skills and implementing them in day-to-day situations outside of treatment.

How is DBT used when clients have BPD?

BPD can present in many different ways. Some individuals experience what is referred to as quiet BPD, where distress is internalized rather than expressed outwardly. These clients may rely on avoidance or self-harm rather than overt emotional outbursts. Other clients may experience intense anger and resort to explosive fights and impulsive behaviors.

Diary cards are one tool I frequently use with clients with BPD. They provide a structured way to track emotions, behaviors, and skill use over time. When a client feels that an intense emotion or panic attack appeared suddenly, diary cards allow us to look back together, identify patterns, and explore which skills may have been helpful in those moments.

Which therapeutic modality is best for treating BPD?

DBT was originally created to treat BPD and is considered the gold standard of care.  One of the defining features of DBT is its emphasis on dialectics, the idea that two seemingly opposing truths can coexist. For example, a person can feel both love and anger simultaneously. Or, a past experience can be both deeply painful and meaningful. Because people with BPD often experience emotions in extremes, DBT’s balance of both change and acceptance can offer one effective framework in treatment.

Could you share more about the skills you learn in CBT and DBT?

Definitely! In CBT clients learn how to reframe their thoughts while also using exposure techniques like Exposure Response Prevention Therapy (ERP).

DBT includes four modules: Mindfulness, Distress Tolerance, Emotion Regulation, and Interpersonal Effectiveness and they all work together. One of my favorite skills from the interpersonal effectiveness unit is called DEAR MAN (which stands for describe, express, assert, reinforce, mindful, appear confident, and negotiate). DEAR MAN helps clients communicate their needs clearly and assertively during difficult conversations.

Clients also learn DBT crisis skills for when they are dealing with intense panic and anxiety. TIPP shocks the body into a calmer state through regulating the nervous system. 

• Temperature: To calm down immediately. Hold an icepack or something frozen against your forehead for 30 seconds.
• Intense Exercise: To feel more peace. Expend your body’s stored energy through jumping jacks or dancing for as little as 30 seconds to 2 minutes.
• Paced Breathing: Slow down your breathing. Breathe in for 4 seconds and out for 4 seconds, holding at the top and bottom of the breath.
• Paired Muscle Relaxation: To relax your body. Tense muscles while breathing in and relax while breathing out, working one section of the body at a time.

In addition to CBT and DBT, what other modalities would you recommend to treat BPD?

BPD is often rooted in early trauma, which makes trauma-informed therapies such as Eye Movement Desensitization and Reprocessing Therapy (EMDR) and Internal Family Systems valuable aspects of treatment. However, it is important that clients first develop DBT skills to manage distress before engaging in deeper trauma work.

Acceptance and Commitment Therapy (ACT) can also be helpful, because often people with BPD struggle to find their sense of identity.  ACT allows clients to investigate their own values and accept past thoughts and beliefs. In addition, family therapy plays a critical role in treatment, as BPD often affects the entire family system. Family therapy provides space for repair, boundary-setting, and establishing more effective communication.

I know you started the Parent DBT group at The Dorm, could you share about why you created that group?

At The Dorm, clients have both coaches and therapists and coaches work with parents in addition to young adults. I realized that many of the challenges that came up in family therapy could be mitigated if both parents and young adults had shared DBT skills.

Many parents begin DBT wondering, “what do I need to teach my young adult?” In the group, we shift that focus toward parents learning and practicing the skills themselves. By modeling mindfulness, validation, and effective communication, families are often able to reduce conflict and prevent sudden escalations.

Can you tell me about research outcomes of DBT treatment for BPD? 

DBT has been extensively studied and consistently shown to be an effective modality for BPD across a wide range of clinical settings. In one study, DBT reduced the need for medication and other medical care by 90%.  The  strong research base behind DBT is why it is considered the gold standard of care.
