CBT vs DBT
DBT, dialectical behavior therapy, is a form of CBT, not its opposite. CBT works on the thoughts and habits that keep problems like depression and anxiety going. DBT adds acceptance and skills for intense emotions, and was built for people who harm themselves or feel suicidal. Neither is better across the board. They were built for different problems.
The short version
- CBT may fit if: You want to work on depression, anxiety, panic, worry or habits, in a set number of weekly sessions.
- DBT may fit if: Emotions swing hard and fast, you harm yourself or think about suicide, or relationships keep blowing up.
| CBT | DBT | |
|---|---|---|
| Built for | Depression, anxiety and many other problems | People who are highly suicidal, often with borderline personality disorder |
| Main idea | Thoughts, feelings and actions feed each other, and can be changed | Accept yourself as you are and change, both at once |
| Format | Weekly individual sessions, often 5 to 15 in the NHS | Individual therapy, a skills group, phone coaching and a therapist team |
| Length | Weeks to months | Often a year in the main trials |
| Skills taught | Thought records, behavioral activation, experiments, exposure | Mindfulness, distress tolerance, emotion regulation, interpersonal effectiveness |
The session counts come from the NHS1, the DBT format from Linehan and Wilks2, and the trial length from Linehan's trials.3
Why DBT exists
Marsha Linehan, a psychologist at the University of Washington, first tried standard CBT with highly suicidal patients who had borderline personality disorder. The university's magazine reported that the approach made them feel their suffering had been discounted.4 In Linehan's words, "They were really sensitive to being told they were the problem."4
Through trial and error, she found the missing piece: acceptance.4 She didn't drop change. She paired the two. DBT grew out of that work.2 "Dialectical" refers to holding two things that seem opposite at the same time: accepting yourself as you are, and working to change.
That history answers a question people type into search engines: "Why is CBT so invalidating?" For some people, a therapy that focuses only on changing thoughts can feel like being told their pain is a thinking error. DBT was Linehan's answer to that.
What each one looks like in practice
In CBT
You and a therapist pick specific problems, look at the thoughts and habits that keep them going, and practice new ones between sessions.5 A thought you'd bring might be:
"I bombed that presentation, so I'm going to lose my job."
You'd look at what fits that thought and what doesn't. Or you'd test it. Our cognitive restructuring and behavioral activation pages show two of the main methods.
In DBT
Standard DBT combines weekly individual therapy, a weekly skills group, phone coaching between sessions, and a consultation team for the therapists.2 The skills come in four areas: mindfulness, interpersonal effectiveness, emotion regulation and distress tolerance.6 A moment you'd bring might be:
"I was so angry after the call that I wanted to smash something. I didn't know what to do with it."
First, you'd work on getting through the next ten minutes without making things worse. Later, on what set it off.
Broad evidence for CBT, deep evidence for DBT
CBT has the broader evidence. A review of 106 meta-analyses found the strongest support for CBT in anxiety disorders, bulimia, anger and general stress.7 For depression, a 2023 analysis of 409 trials found moderate to large effects against usual care or waiting lists, but only a small edge over other therapies.8
DBT has strong evidence for one group. Linehan's first trial, in 1991, gave women with borderline personality disorder who repeatedly harmed themselves a year of DBT or usual care. Those in DBT harmed themselves less frequently, and less seriously. More of them stayed in therapy. Depression and hopelessness improved in both groups, about equally.3
It held up against expert therapists, too. Women who had DBT were half as likely to make a suicide attempt as women treated by experienced non-behavioral therapists, in a 2006 trial of 101 women.9 Fewer dropped out.9
The wider evidence is less certain than it sounds.
A 2020 Cochrane review pooled 75 trials of therapies for borderline personality disorder, and DBT was the subject of a third of them.10 Against usual care, DBT reduced the severity of borderline symptoms and self-harm, and improved day-to-day functioning. All three findings were rated low quality.10 When the reviewers compared types of therapy against usual care, they found no clear difference between them for borderline symptoms or day-to-day functioning.10
For ADHD, there's a CBT trial to point to: 12 sessions of CBT lowered ADHD symptoms more than relaxation training did, for 86 adults already on medication.11
How to choose
- Start with the main problem. Low mood, worry, panic or a stuck habit points to CBT. Intense emotions, self-harm, suicidal thoughts or chaotic relationships point to DBT.
- Ask about format and time. DBT is usually a bigger commitment: individual sessions plus a weekly group, for a year in the main trials.3
- Ask the therapist what they do in sessions. "What does a typical session look like?" and "Do you offer a skills group and phone coaching?" A full DBT program includes both.2
- Notice how it feels after a few sessions. Does it leave you feeling your pain is being argued with? Say so. A good therapist will adjust, or suggest another approach.
Where to find each
The Association for Behavioral and Cognitive Therapies has a Find a CBT Therapist directory. For DBT, there's one question to ask. Does the program follow the full model, with a skills group and phone coaching?
Think about the last time you felt overwhelmed. Was the hardest part the thought that came with it, or the strength of the feeling itself? Write a few lines. What happened, and what did you need right then?
Answer this with JoyQuestions people ask
What is the main difference between CBT and DBT?
Past the ideas, the setup differs. CBT is usually one therapist and you, weekly, for a set run of sessions.1 Full DBT is a program: your therapist, a skills group, phone coaching between sessions, and a team that backs up the therapist.2
Is DBT better than CBT?
Not in general. DBT has the strongest evidence for self-harm and borderline personality disorder.10 CBT has evidence across many more problems, such as depression and anxiety.7
Who is DBT not recommended for?
There's no single list. DBT is intensive. For mild anxiety or a single phobia, it can be more than you need, and a shorter course of CBT is often the place to start.
Can you do CBT and DBT at the same time?
Usually there's no need. DBT already includes CBT methods. If you're in one, ask your therapist before adding the other.
