What is the difference between CBT, DBT, and EMDR?
Last reviewed: May 2026
When you are researching therapy, you will encounter a range of acronyms — CBT, DBT, EMDR, ACT, IFS. These are not competing philosophies so much as different tools designed for different situations. Here is a clear, practical overview of the most common ones.
Cognitive Behavioural Therapy (CBT)
CBT is the most widely researched form of psychotherapy and has the strongest evidence base across the widest range of conditions — including depression, anxiety disorders, OCD, phobias, and insomnia. CBT is based on the understanding that our thoughts, emotions, and behaviours are interconnected, and that changing unhelpful thought patterns and behavioural habits can shift emotional experience.
CBT is typically structured and time-limited. Sessions often include worksheets, between-session exercises, and a collaborative focus on identifying specific automatic thoughts and challenging their accuracy. If you are looking for a focused, skills-based approach that produces measurable change within a defined time period, CBT is a strong option.
Dialectical Behaviour Therapy (DBT)
DBT was originally developed by Marsha Linehan for individuals with Borderline Personality Disorder and has since been extended to a range of conditions involving emotional dysregulation — including self-harm, suicidality, eating disorders, and substance use. DBT combines CBT techniques with mindfulness-based approaches and emphasizes four core skill areas: mindfulness, distress tolerance, emotional regulation, and interpersonal effectiveness.
Full DBT programs are intensive — they typically include individual therapy, group skills training, and therapist phone coaching. Modified DBT elements (specific skills modules without the full program) are also frequently incorporated into individual therapy for people who struggle with emotional intensity.
EMDR (Eye Movement Desensitization and Reprocessing)
EMDR is a specialized approach developed specifically for trauma. It is endorsed by the World Health Organization (WHO) and has the strongest evidence base of any approach for PTSD. The core of EMDR involves bilateral stimulation (often side-to-side eye movements, though tapping or auditory tones are also used) while the client holds a targeted traumatic memory in mind. This process appears to help the brain reprocess stored traumatic material so that it loses its intrusive, activating quality.
EMDR does not require you to talk through your trauma in detail, which makes it more accessible for people who find verbal processing of traumatic events retraumatizing. The process works at the level of how the memory is stored in the nervous system, not just at the cognitive level.
