What is DBT? A plain-English guide to Dialectical Behaviour Therapy (Calgary)

Dialectical Behaviour Therapy (DBT) is a comprehensive, evidence-based treatment that combines weekly individual therapy, weekly skills groups, between-session phone coaching, and therapist consultation. DBT teaches four skill sets (mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness) and is the leading treatment for Borderline Personality Disorder, chronic emotion dysregulation, and self-harm.

Where DBT came from

DBT was developed in the 1990s by Marsha Linehan for clients with BPD and chronic suicidality, where standard CBT was producing high dropout and limited results. Linehan integrated CBT with mindfulness, acceptance, and dialectical philosophy (the holding of opposites: acceptance and change at the same time).

The core idea

Some clients arrive at therapy with regulation systems so overwhelmed that standard symptom-focused therapy cannot land. They need the underlying capacity built first. DBT teaches the skills that make emotion regulation possible, while also accepting that the client is doing the best they can with what they have, while also working to do better. The "dialectic" is the holding of acceptance and change simultaneously.

The four DBT skill modules

  1. Mindfulness: the foundation. Being present with what is, without judgment.
  2. Distress tolerance: getting through crisis without making it worse.
  3. Emotion regulation: identifying, reducing, and changing emotional responses.
  4. Interpersonal effectiveness: getting needs met, maintaining relationships, keeping self-respect.

What DBT is used for

  • Borderline Personality Disorder (the original target)
  • Chronic suicidality and self-harm
  • Eating disorders with emotion regulation as a primary driver
  • Substance use with emotion drivers
  • Chronic emotion dysregulation regardless of diagnosis
  • Adolescents with severe emotional reactivity
  • Complex PTSD with significant dysregulation
  • Bipolar disorder as an adjunct

What full DBT looks like versus DBT-informed therapy

Full DBT is an intensive programme: weekly individual therapy, weekly 2-hour skills group, between-session phone coaching, and the therapist participates in a weekly consultation team. The full programme is typically 6 to 12 months and is intensive but powerful.

DBT-informed individual therapy uses DBT skills and frameworks without the full programme structure. It works well for clients with significant emotion regulation needs who do not require the full intensity.

What a DBT session looks like

Individual sessions are structured around a hierarchy of priorities: life-threatening behaviours first, therapy-interfering behaviours second, quality-of-life issues third. The therapist uses a balance of validation and change-focused interventions. Skills group is psychoeducational and structured around the four modules.

Evidence base

DBT has decades of research support and is the most evidence-supported treatment for BPD. It also has strong evidence for self-harm, suicidality, substance use, and eating disorders. Major treatment guidelines recommend it.

Common misconceptions about DBT

DBT is not only for BPD. It works for many emotion regulation presentations. DBT skills are not just self-help worksheets. They are taught and practiced in a structured clinical context. DBT does not invalidate the client. The validation component is core to the work.

When DBT is not the right fit

DBT may not be the first move for clients whose primary issue is specific anxiety, OCD, or trauma without significant dysregulation. For those, more focused approaches (CBT, ERP, EMDR) often work efficiently.
