Types of Therapy Explained: CBT, DBT, EMDR, ACT and More

If you have started looking for a therapist, you have probably run into a wall of short letters: CBT, DBT, EMDR, ACT. It can feel like everyone speaks a language you were never taught. That is a normal reaction, and it is not a sign that therapy is not for you. These letters are just names for different ways of doing talk therapy.

This guide explains, in plain language, what some of the most common therapy approaches are and what each is generally used for. Our goal is not to tell you which one you need. That is a decision you make together with a qualified professional who can get to know your situation. Our goal is to help you feel more prepared, ask better questions, and worry a little less when you reach out for help.

If you need support right now

Learning about therapy is a slower, planning kind of step. If you are in crisis today, please skip ahead and reach out now.

If you or someone you know is in crisis or thinking about suicide, call or text 9-8-8 (Canada's Suicide Crisis Helpline), available 24/7, or call 9-1-1 or go to your nearest emergency department.

You do not need a diagnosis or a therapist to make that call. Support is there for anyone who needs it.

Does talk therapy actually help?

It is fair to wonder whether talking to someone really makes a difference. According to the Canadian Psychological Association, established psychological treatments for depression are "roughly as successful as pharmacotherapy," meaning about as helpful as medication for many people.[2] The same source notes that people also tend to stay in therapy more than they stay on medication, and that some approaches may lower the chance of depression coming back later.[2]

For ongoing worry and anxiety, the Canadian Psychological Association reports that psychological therapy is very effective for generalized anxiety disorder. In one Canadian study it cites, 77 percent of people who received short-term therapy were still free of the disorder a year after treatment ended.[3]

These are encouraging findings, not promises. Everyone is different, and no honest professional can guarantee a result. What the evidence does suggest is that therapy is a real, well-studied form of help that works for many people.

Common types of therapy

Below are four approaches you are likely to hear about, plus a few others. Read them as background, not as a checklist to sort yourself into. Matching an approach to a person is skilled work, and it is a job for a trained clinician.

Cognitive behavioural therapy (CBT)

CBT is one of the best-known talk therapies. The Centre for Addiction and Mental Health (CAMH) describes it as "a practical, short-term form of psychotherapy," usually 6 to 20 sessions, that is structured and focused on the problems you face day to day.[1] The core idea is that our thoughts, feelings, and actions are linked, so learning to notice and question unhelpful thinking patterns can change how we feel and cope.[1]

CAMH notes that evidence "suggests that it is particularly effective in treating anxiety and depression," and that CBT is also used for a range of other concerns, from panic and phobias to obsessive-compulsive disorder.[1] Because it teaches concrete skills you can keep using, many people find it a practical place to start.

Dialectical behaviour therapy (DBT)

DBT grew out of CBT but adds a strong focus on managing intense emotions. CAMH calls it "an evidence-based model of therapy that helps people learn and use new skills and strategies so that they build lives they feel are worth living."[4] The word "dialectical" points to holding two ideas at once: accepting yourself as you are, while also working toward change.[4]

DBT usually combines individual sessions with a skills group that covers mindfulness, handling distress, managing emotions, and getting along with others.[4] It was first developed for borderline personality disorder, and CAMH notes it can also help with concerns such as self-harm, suicidal behaviour, substance use, and eating disorders.[4] It tends to be a bigger commitment than short-term CBT.

Eye movement desensitization and reprocessing (EMDR)

EMDR is a therapy designed for people affected by trauma. The U.S. Department of Veterans Affairs National Center for PTSD describes it as "a trauma-focused psychotherapy that is one of the most studied treatments for posttraumatic stress disorder (PTSD)."[6] During EMDR, you briefly bring a difficult memory to mind while the therapist guides a back-and-forth movement, often of the eyes, to help the memory feel less overwhelming over time.[6]

Guidelines differ on exactly how strongly to recommend it. The American Psychological Association's guideline "suggests" EMDR for PTSD as a second-line option, while its cognitive-behavioural therapies are strongly recommended.[5] The Veterans Affairs review notes that several other major guidelines give EMDR their highest recommendation.[6] The honest summary: it is a well-studied trauma therapy that helps many people, and a clinician can talk through whether it fits you.

Acceptance and commitment therapy (ACT)

ACT takes a slightly different angle. Instead of trying to argue with or get rid of difficult thoughts, it helps you make room for them while you take actions that matter to you. It leans on acceptance, mindfulness, and living by your personal values. A 2025 review in the journal Cureus reports that research, including meta-analyses and randomized controlled trials, supports ACT's usefulness across a range of mental health concerns.[7] The same review is careful to note real limits: fewer long-term studies, and gaps in research across different cultures and age groups.[7] So the evidence is promising, and still growing.

And a few more

Therapy is a wide field, and these are not the only options. You may also come across interpersonal therapy, which focuses on relationships and life changes; psychodynamic therapy, which explores how past experiences shape the present; mindfulness-based approaches; and couples or family therapy. Each has its own style, and many good therapists blend ideas from several. If a name comes up that you do not recognize, it is completely reasonable to ask the therapist to explain it in plain words.

How the right approach gets chosen

Here is the reassuring part: you do not have to figure this out alone, and you should not try to. A qualified professional starts by getting to know you, your history, your goals, and what has and has not helped before. From there, they suggest an approach, and they adjust as they learn what works for you. Naming what you are going through, and choosing a treatment, are their job, not something to settle from a website.

It also helps to know that the "type" of therapy is only one piece. Research over the years keeps pointing to the same thing: a trusting, comfortable relationship with your therapist matters a great deal. If a particular approach or person does not feel right, it is okay to say so and to try someone else.

The bottom line

CBT, DBT, EMDR, and ACT are not competing brands you have to rank. They are different, well-studied tools, and a trained professional helps match the right one, or the right mix, to you. Talk therapy is a real and effective form of support for many people, though results vary and no one can promise an outcome. The most important step is simply reaching out.
