The short version
- •DBT is a structured, skills-based therapy — an offshoot of CBT — designed for people who feel emotions intensely and struggle to regulate them, originally developed for chronic suicidality and borderline personality disorder.
- •It balances two things in tension (the "dialectic"): radical acceptance of yourself as you are, and commitment to changing behaviors that cause suffering.
- •It teaches four concrete skill sets: mindfulness, distress tolerance (getting through crises without making them worse), emotion regulation, and interpersonal effectiveness.
- •Standard DBT combines weekly individual therapy, a weekly skills group, and between-session phone coaching, usually over several months to a year.
- •It has the strongest evidence of any treatment for borderline personality disorder and for reducing self-harm and suicidal behavior, and its skills help with emotion dysregulation across many conditions.
- •DBT skills pair well with ketamine: emotion-regulation and distress-tolerance skills give patients tools to work with whatever surfaces during and after sessions.
What it is
Dialectical behavior therapy is a structured cognitive-behavioral treatment developed by Marsha Linehan for people with pervasive difficulty regulating emotions — those who experience feelings more intensely, react faster, and return to baseline more slowly than others. The "dialectic" at its center is the balance between acceptance and change: DBT validates that a person is doing the best they can while also insisting they can and must build new skills. Treatment is explicitly skills-focused, teaching four modules — mindfulness (observing experience without being swept away), distress tolerance (surviving crises without self-destructive behavior), emotion regulation (understanding and shifting emotional responses), and interpersonal effectiveness (asking, refusing, and maintaining relationships and self-respect). Comprehensive DBT is a package: individual therapy to apply skills to the person's life, a weekly skills-training group, phone coaching to use skills in real-time crises, and a therapist consultation team. It targets life-threatening behaviors first, then therapy-interfering and quality-of-life-interfering behaviors.
What it helps with
Borderline personality disorder
The first-line, best-evidenced treatment, reducing self-harm, suicidality, hospitalization, and emotional instability.
Emotional dysregulation
The core target of DBT; its emotion-regulation and distress-tolerance skills directly address intense, fast-shifting emotions across diagnoses.
Suicidal thoughts
DBT has strong evidence for reducing self-harm and suicidal behavior, especially when these are recurrent.
DBT skills (and DBT-PE) help trauma survivors build the regulation capacity needed to tolerate trauma-processing work.
What to expect
A package, not just sessions
Comprehensive DBT combines weekly individual therapy, a weekly skills group, and between-session phone coaching, supported by a therapist consultation team.
Skills you practice
You learn and rehearse concrete skills across four modules (mindfulness, distress tolerance, emotion regulation, interpersonal effectiveness) and apply them to real situations.
Duration
Standard programs run roughly six months to a year; skills groups often cycle through the full curriculum more than once.
Crisis coaching
Phone coaching helps you use skills in the moment of a crisis — a distinctive feature that builds real-world capacity.
The evidence
DBT is the most rigorously studied treatment for borderline personality disorder and is recommended first-line for it. Systematic reviews of psychotherapies for BPD (Storebø 2020) find DBT reduces self-harm, suicidal behavior, and symptom severity. Its skills-based components have growing evidence for emotion dysregulation more broadly — across mood, trauma, eating, and substance-use disorders — and adapted forms (such as DBT skills groups) are used widely beyond BPD. The combination of acceptance and change, structured skills, and in-the-moment coaching is what distinguishes it from standard CBT for this population.
How it pairs with ketamine
For patients whose emotions run intense and fast, DBT and ketamine address different layers of the same problem. Ketamine can rapidly reduce the depressive and suicidal load that makes everything harder, while DBT builds the durable, real-world skills to regulate emotion and tolerate distress without self-destructive behavior. The distress-tolerance and emotion-regulation skills are also genuinely useful around ketamine sessions: they give a person concrete tools to work with whatever difficult material surfaces, and to integrate it afterward. Where suicidality is part of the picture, ketamine's rapid anti-suicidal effect and DBT's longer-term risk reduction are complementary — though neither replaces a crisis service.
Frequently asked
Is DBT only for borderline personality disorder?
No. DBT was developed for BPD and chronic suicidality and has its strongest evidence there, but its skills — mindfulness, distress tolerance, emotion regulation, interpersonal effectiveness — help with emotion dysregulation across many conditions, including mood, trauma, eating, and substance-use disorders. Skills groups are widely used beyond BPD.
How is DBT different from CBT?
DBT grew out of CBT but adds a strong emphasis on acceptance (not just change), a structured four-module skills curriculum, in-the-moment phone coaching, and a specific focus on intense emotion and self-destructive behavior. Standard DBT is also a multi-part package rather than individual sessions alone.
How long does DBT take?
Comprehensive DBT typically runs six months to a year, with weekly individual therapy and a weekly skills group; many programs cycle through the full skills curriculum more than once. Briefer skills-only groups exist for people who mainly want the regulation tools.
Can DBT help with suicidal thoughts?
Yes — reducing self-harm and suicidal behavior is one of DBT's best-established effects, particularly when these are recurrent. DBT is not a crisis service; if you are in immediate danger, call or text 988. But as ongoing treatment, it builds real capacity to get through crises safely.
