DBT and Borderline Personality Disorder (BPD) - The Connection Between the Therapeutic Approach and Borderline Personality Disorder

Borderline personality disorder is a mental disorder characterized by an enduring pattern of difficulties with emotional regulation, relationships, self-image and sometimes impulse control. Manifestations may include an intense fear of abandonment, sharp shifts in how the person perceives themselves and others, a persistent sense of emptiness and anger that is difficult to regulate. Some people also experience self-harming behaviors, suicidal thoughts or risky behaviors.

However, not every person with BPD experiences all the symptoms, and the way the disorder manifests can vary significantly between individuals.

Diagnosis requires a professional clinical assessment, and its presence should not be inferred from a single behavior or a turbulent relationship.

Psychologist Marsha Linehan developed DBT through her work with patients who experienced severe emotional distress and repeated self-harming and suicidal behaviors. One of the central challenges in treatment was the tension between the patients’ need to feel understood and accepted and the need to change behaviors that harmed them. An approach focused only on change could be experienced as critical. Conversely, acceptance without work on change did not always address dangerous behaviors. From this emerged the central dialectical principle of treatment: acceptance and change can coexist.

One possible characteristic of BPD is heightened sensitivity to situations perceived as signs of abandonment or withdrawal. A change in tone of voice, a canceled meeting or a delayed response to a message may evoke significant distress. Sometimes the person responds with repeated attempts to obtain reassurance about the relationship, accusations or initiating withdrawal to avoid possible hurt.

DBT involves identifying the pattern linking the fear of abandonment with behavior, and developing ways to ask for closeness and security without harming the relationship.

Some people with BPD may find it difficult to hold complex feelings and perceptions about themselves and others simultaneously. Someone close may be perceived as loving and caring, but following disappointment may be experienced as unreliable or uncaring. This pattern is sometimes called dichotomous thinking, and it is not unique to borderline personality disorder.

The dialectical approach helps develop the ability to hold two perspectives that do not cancel each other out. For example: "I am hurt by my partner, and at the same time I know that they love me".

For some people living with BPD, self-harm may serve as an attempt to reduce emotional distress, stop a feeling of dissociation or cope with emotions experienced as unbearable. It is important to understand the role the behavior serves for the person, without justifying it or minimizing the associated risk.

DBT uses behavioral analysis to identify the circumstances preceding the harm, the emotional responses and the consequences that maintain the pattern.

Alternative skills for coping with distress are then learned, alongside safety planning and interventions appropriate to the level of risk.

Standard DBT is a structured treatment that usually includes several interconnected components.

Individual therapy: work on behaviors that compromise safety, the therapeutic process and quality of life, alongside strengthening new skills.

Skills training: learning and practicing practical tools in mindfulness, distress tolerance, emotional regulation and interpersonal effectiveness.

Telephone coaching between sessions: within an appropriate framework, support in applying skills in real-life situations.

Therapist consultation team: a professional framework that helps therapists maintain consistency and fidelity to the principles of the approach.

It is important to distinguish between comprehensive DBT treatment and treatment that incorporates DBT skills, which does not necessarily include all the components of the model.

One of the central aims of DBT is to help a person build a life they experience as worth living. Therefore, alongside reducing risky behaviors and recurring crises, treatment also addresses the development of stability, meaningful relationships, independence and daily functioning.

Goals are tailored to the patient’s individual needs and may include improving relationships, professional advancement, developing interests and strengthening a sense of meaning.

Yes. Long-term follow-up studies indicate that many people with BPD experience a significant reduction in symptoms over the years, and some no longer meet the diagnostic criteria. However, improvement in symptoms does not guarantee that all functional and interpersonal difficulties will disappear.

DBT is one of the treatments found to be effective, particularly in reducing self-harm and suicidal behaviors, but other evidence-based therapeutic approaches also exist.

The recovery process is not uniform, and is influenced by personal characteristics, co-occurring conditions and therapeutic and environmental support.

Borderline personality disorder is a clinical diagnosis describing certain patterns of difficulty, but it does not define the entirety of a person’s personality. Behind intense reactions may lie pain, fear, a need for closeness and difficulty finding effective ways to cope with distress.

The DBT approach offers a therapeutic framework combining a deep understanding of the difficulty with systematic work on behavioral change.

The central message of the approach is that even when emotional and behavioral patterns have accompanied a person for years, it is possible to learn new ways to cope, build more stable relationships and improve quality of life.
