  • 03

    It has the strongest evidence for borderline personality disorder and repeated self-harm, and helps wider emotional dysregulation.

  • 04

    Dialectical means holding acceptance and change together - you are doing your best, and you can learn to do better.

  • 05

    Programmes run in NHS and private settings; ask about therapist training and whether the full model or skills-only version is offered.

Understanding it

What it is, and how to get help.

In plain English - what is going on, and the assessment and treatment routes available in the UK.

DBT was developed specifically for people whose emotions overwhelm standard therapy, combining warm validation with unapologetically practical skills training. It treats emotional dysregulation as a skills deficit that can be closed, not a character flaw.

A full programme typically runs six months to a year; skills-only groups and DBT-informed individual therapy offer lighter-touch versions where the full model is not needed or available. NHS talking-therapy waits vary widely and can be lengthy, particularly for specialist or longer-term therapy. Privately, an initial appointment with a psychologist or accredited therapist can typically be arranged within around two weeks.

Frequently asked

Common questions about DBT explained.

Quick, plain-English answers to what people ask us most.

  • What is DBT (dialectical behaviour therapy)?

    Dialectical behaviour therapy (DBT) is a skills-based psychological treatment originally developed for emotional dysregulation and self-harm, combining acceptance-based and change-focused strategies to help people manage intense emotions.

  • Who is DBT designed for?

    DBT was originally developed for borderline personality disorder and chronic self-harm or suicidal thoughts, but it's now used more broadly for various conditions involving difficulty regulating intense emotions.

  • What does DBT involve?

    DBT typically combines individual therapy, skills training groups (covering mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness), and often between-session phone coaching for support during crises.

  • Is DBT effective?

    Yes, DBT has strong evidence supporting its effectiveness, particularly for reducing self-harm and improving emotional regulation in people with borderline personality disorder and related difficulties.

  • How long does a course of DBT take?

    A full DBT programme is typically structured over about six months to a year, reflecting the substantial skills-building and practice needed to genuinely change ingrained patterns of emotional response.

  • What are the four main skill modules in DBT?

    The four core modules are mindfulness (present-moment awareness), distress tolerance (coping with crisis without making things worse), emotion regulation (understanding and managing emotions), and interpersonal effectiveness (navigating relationships and communication).

  • DBT vs CBT - what's the difference?

    Standard cognitive behavioural therapy (CBT) focuses primarily on changing unhelpful thoughts and behaviours, while DBT specifically adds acceptance-based strategies and intensive skills training aimed at people who struggle with very intense, hard-to-regulate emotions.

  • Does DBT require group therapy?

    Full DBT programmes typically include both individual therapy and group skills training, since the group format is specifically designed to teach and practise the four skill modules alongside others.

  • Can DBT help with conditions other than borderline personality disorder?

    Yes, DBT principles and skills are increasingly used for other conditions involving emotional dysregulation, including some eating disorders, substance use difficulties, and mood disorders, adapted to the specific presentation.

  • When should I consider DBT?

    Consider DBT if you struggle with intense emotions, self-harm, or unstable relationships that haven't responded well to standard therapy. A private psychology or psychiatry consultation can often assess suitability within about two weeks.
