Dialectical behavior therapy

What DBT is

DBT is a cognitive-behavioral treatment with two features that set it apart from other CBT variants.

The first is dialectics. DBT holds two apparently opposite ideas at once, most centrally acceptance and change. The client is worked with as they are, without pathologizing them or their history (radical acceptance), and simultaneously asked to make specific behavioral changes (change). The therapist moves between those two stances deliberately, refusing to collapse them into either "you need to try harder" or "your feelings are valid, so don't worry about it." This dialectical stance is drawn from Linehan's integration of behavior therapy with Zen practice and Hegelian dialectics, and it addresses a specific therapeutic problem that arose when Linehan tried to use standard CBT with chronically suicidal patients: the change-focused stance felt invalidating to people whose experience had been consistently invalidated, and the invalidation predictably increased suicidality.

The second is the structured multi-component format. DBT is not a technique; it's a program. The four modes work together, and outcomes suffer substantially when programs try to run one or two modes in isolation and call it DBT.

The four modes of a standard adherent DBT program

Individual therapy. One 50 to 60 minute session per week. The therapist and patient work through a target hierarchy: any life-threatening behaviors first (suicide attempts, non-suicidal self-injury, homicidal ideation), then behaviors that interfere with treatment (missed sessions, late arrivals, refusal to complete diary cards), then behaviors that seriously affect quality of life (substance use, relationship crises, employment problems), then working on skills, then on the person's larger goals. This hierarchy isn't rigid, but it protects the treatment from drifting away from the things most likely to harm the person.

Each session begins with review of the diary card the patient completed that week: urges, actions, emotions, skill use, medications taken. This provides real-time data about what's actually happening rather than relying on the patient's summary at the start of session.

Skills training group. Two to two and a half hours per week. Runs as a class with a teacher rather than a support group. Two therapists co-lead. Six to eight patients typical. Teaches four skill modules (see below) over about six months, then cycles again. Standard DBT includes at least two full cycles of skills training (one year of group).

Phone coaching between sessions. Brief phone contact (usually 10 to 15 minutes) initiated by the patient when they need help applying a skill in the moment. The purpose is generalization of skills to real life, not extra therapy. There are specific rules about when to call and what the coaching covers. Phone coaching is one of the more distinctive features of DBT and reduces reliance on emergency room visits during crises.

Consultation team. The therapists meet weekly for one to two hours. This isn't optional; it's part of the treatment. DBT recognizes that working with people whose baseline includes suicidal behavior, chronic emotional intensity, and repeated crises is difficult work that can produce clinician burnout, subtle drift from adherent treatment, and unhelpful reactions to patients. The consultation team's job is to keep the therapists on track, provide support, and prevent the accumulated wear that leads to poor outcomes.

Adherent programs stay close to this structure. Adapted versions exist and are useful in the settings where they've been studied (see below), but "DBT-informed" treatment that offers only a skills group without individual therapy is a different treatment, not DBT.

Who DBT is for

The original and best-evidenced use is for borderline personality disorder, particularly when chronic suicidal behavior or non-suicidal self-injury is part of the picture. Randomized trials over more than thirty years show reduced suicide attempts, reduced self-harm, reduced psychiatric hospitalizations, better retention in treatment, and improved function. Linehan et al. (2015 JAMA Psychiatry) confirmed that the full DBT package (with individual therapy and skills group) produced better outcomes than skills group alone or individual therapy alone.

Beyond BPD, DBT or DBT-informed treatment has evidence for use in:

• Chronic suicidal ideation, including without a personality disorder diagnosis
• Non-suicidal self-injury
• Bulimia nervosa and binge eating disorder (Safer, Telch, and Chen manuals)
• Substance use disorders when a personality disorder or mood dysregulation is present (DBT-SUD, Linehan and colleagues)
• Adolescents with emotional and behavioral dysregulation (DBT-A, adapted format includes family; Miller, Rathus, and Linehan manual)
• PTSD with severe dysregulation (DBT-PTSD, adapted protocol by Bohus and colleagues)
• Bipolar disorder as an adjunct to standard treatment
• Treatment-resistant depression with prominent dysregulation

The common feature across these uses is difficulty regulating strong emotions. DBT is not the first-line treatment for depression alone, or generalized anxiety alone, though it can be useful when those conditions are complicated by dysregulation and impulsivity.

Radically open DBT (RO-DBT) is a related but distinct treatment developed by Tom Lynch for over-controlled disorders (chronic depression, anorexia nervosa, obsessive-compulsive personality disorder, autism spectrum in some contexts). It targets emotional loneliness and rigidity rather than emotional dysregulation, and it's a different treatment from standard DBT despite sharing some structural features.

The four skill modules in detail

Mindfulness is taught first and is considered the core skill on which all other skills rest. It's not a spiritual practice in DBT, though it draws on Zen tradition. It teaches specific "what skills" (observing, describing, participating) and "how skills" (non-judgmentally, one-mindfully, effectively). The point is developing the capacity to notice what you're feeling and doing without having to change it or hate it in the same moment. Wise mind, the state that integrates emotion mind and reasonable mind, is a specific target.

Distress tolerance teaches ways to get through crisis moments without making the situation worse. It's not about feeling better; it's about getting through a bad moment safely so longer-term change is possible. Skills include:

• TIP (Temperature, Intense exercise, Paced breathing, Paired muscle relaxation) for rapid physiological shifts when the mind cannot slow down
• ACCEPTS (Activities, Contributing, Comparisons, Emotions, Push away, Thoughts, Sensations) for skillful distraction
• IMPROVE (Imagery, Meaning, Prayer, Relaxation, One thing at a time, Vacation, Encouragement) for improving a bad moment
• Self-soothing through the five senses
• Radical acceptance for situations that cannot be changed
• Pros and cons of the urge for evaluating destructive impulses before acting

Emotion regulation teaches understanding what emotions do (biological functions, communicative functions, action tendencies), reducing vulnerability to intense emotions (the PLEASE skills: treat PhysicaL illness, balance Eating, avoid mood-Altering substances, balance Sleep, get Exercise), and changing emotional responses through opposite action, problem solving, and building positive experience. Cognitive reappraisal is included but is not the primary tool; DBT recognizes that emotional regulation often works better through behavioral and physiological routes than through trying to think differently.

Interpersonal effectiveness teaches skills for asking for what you need, keeping relationships intact, and keeping self-respect across situations that used to end in withdrawal, escalation, or agreement-under-duress. Key acronyms:

• DEAR MAN (Describe, Express, Assert, Reinforce, Mindful, Appear confident, Negotiate) for asking or saying no
• GIVE (Gentle, Interested, Validate, Easy manner) for keeping the relationship in mind
• FAST (Fair, Apologies avoided, Stick to values, Truthful) for keeping self-respect

Skills are taught in group, practiced with homework, and worked through in individual therapy when they aren't sticking. Learning a skill in a class is not the same as being able to use it during an actual overwhelming moment; the individual sessions and the phone coaching exist to bridge that gap.

What a session actually looks like

Individual sessions typically start with the person's diary card: a week's worth of tracked urges, actions, feelings, and skill use. The therapist and patient then work through the target hierarchy: any life-threatening behaviors first, then anything that interfered with treatment, then anything that seriously affected quality of life, then skills work.

Behavior chain analysis is the primary tool for understanding specific incidents. The person and therapist walk through a specific behavior (a suicide attempt, a fight, an episode of substance use, a skipped session) in fine detail: what happened just before, what the vulnerability factors were, what emotions arose, what thoughts came up, what actions followed, what consequences resulted. This produces both understanding and specific plans for interrupting the chain next time.

The therapist's stance combines validation with pushing for change. Validating a person's feelings as making sense given their history and their nervous system does not require agreeing that their next planned action is a good idea. The dialectic is held explicitly rather than resolved.

Common therapeutic techniques include problem-solving, exposure, cognitive modification, contingency management, and skills coaching. What's distinctive is not the techniques themselves but the specific combination and the dialectical stance.

What the evidence shows

Standard DBT for BPD has been studied in over a dozen randomized controlled trials since Linehan's original 1991 trial in Archives of General Psychiatry. Consistent findings across studies:

• Reduction in suicide attempts and non-suicidal self-injury
• Reduction in psychiatric hospitalizations
• Improvement in treatment retention (people stay with DBT better than with treatment as usual, often the largest effect)
• Improvement in overall function and quality of life
• Reduction in anger and depression

Treatment effect sizes are moderate to large depending on outcome. Effects tend to hold at one and two year follow-up.

Kliem, Kröger, and Kosfelder (2010) meta-analysis of DBT for BPD in Journal of Consulting and Clinical Psychology found moderate global effects with strongest effects on suicidal behavior.

Linehan et al. (2015) JAMA Psychiatry component analysis compared standard DBT (all four modes) with DBT skills group plus individual therapy without DBT protocols, and with DBT individual therapy plus activities group. All three produced improvement, but standard DBT produced the strongest and most durable results, particularly on suicidal behavior.

McMain et al. (2009) American Journal of Psychiatry compared DBT with general psychiatric management (structured, expert-informed treatment as usual) for BPD. Both produced substantial improvement, and outcomes were similar. This finding is important: it suggests that structured, expert-informed treatment for BPD is effective, and DBT is one such treatment. Choice between DBT and other structured BPD treatments (mentalization-based therapy, transference-focused psychotherapy) is often about availability and fit rather than superiority.

For other conditions: - Eating disorders: Safer et al. and colleagues have shown DBT skills groups produce meaningful outcomes in binge eating disorder and bulimia - Adolescents: Multiple trials of DBT-A show effectiveness for suicidal behavior, non-suicidal self-injury, and BPD features - Substance use with BPD: DBT-SUD trials show reduction in substance use alongside standard DBT outcomes - PTSD: DBT-PTSD trials (Bohus and colleagues) show meaningful outcomes in patients with severe dysregulation who couldn't tolerate standard trauma-focused treatment

What the evidence does not show: that DBT is better than every other treatment for every problem, or that DBT skills learned outside a full program produce the same results as full DBT. Skills learned in a book, an app, or a weekend workshop are useful but not the same treatment.

What DBT is not

DBT is not group therapy for people who feel overwhelmed. That's a common misunderstanding. Group is one of four modes. Doing group without the other three modes is a DBT-informed treatment, not DBT.

DBT is not only for people with borderline personality disorder. It's often the best-fit treatment for BPD, but it's used more broadly.

DBT is not a lifetime treatment. Standard programs run about a year, sometimes extended to two. What continues afterward is the person's use of the skills and, often, less-intensive follow-up care.

DBT is not a replacement for medication when medication is indicated. Some people in DBT are on no medications; many are on medications for co-occurring conditions. Coordination between the individual therapist, medication prescriber, and skills group leaders is standard.

DBT is not incompatible with trauma-focused work. After a period of stabilization in standard DBT, patients with trauma histories can often move into trauma-focused treatment (either DBT-PTSD or other trauma treatments) with much more capacity to tolerate the work than they had at intake.

Finding DBT

The single most important thing to look for is program fidelity. Programs that offer all four modes and whose therapists are trained in the model and get regular consultation are more likely to deliver the outcomes seen in trials. Programs that offer skills group only, or individual therapy with a "DBT-informed" label, are useful but different treatments.

Certification. The DBT-Linehan Board of Certification certifies individual clinicians and programs that meet specific adherence criteria. Certified programs are relatively rare but represent the highest fidelity standard.

Intensive training. The gold standard clinician training in DBT is Intensive Training conducted by Behavioral Tech (founded by Linehan), which involves prework, two five-day training modules, and clinical work in between. Not every DBT clinician has this training, and the field includes clinicians with varying levels of formal DBT preparation.

Insurance coverage. In the United States, intensive outpatient DBT programs are covered by many insurers but not all, and coverage for the full skills group component can be uneven. Community mental health centers in many states offer publicly funded DBT programs. Some academic medical centers offer DBT.

International availability. DBT is widely available in the UK (often through NHS trusts), Canada, Australia, New Zealand, and much of Europe. Availability in other regions varies substantially.

Behavioral Tech and the DBT-Linehan Board of Certification maintain public directories of certified providers and programs.

Adapted formats

DBT-A (adolescents). Adapted by Miller, Rathus, and Linehan. Includes a fifth skill module called Walking the Middle Path that addresses adolescent-specific dialectics between developmental autonomy and family involvement. Family members typically participate in skills group.

DBT-PTSD. Adapted by Martin Bohus and colleagues for patients with severe PTSD from childhood abuse who couldn't tolerate standard trauma-focused therapies. Integrates DBT skills with modified trauma exposure work. Bohus et al. (2020 JAMA Psychiatry) showed effectiveness compared with cognitive processing therapy.

DBT-SUD. Adapted by Linehan and colleagues for substance use disorders with co-occurring BPD or severe dysregulation. Adds specific substance-focused targets to the treatment hierarchy.

DBT for eating disorders. Adapted by Safer, Telch, and Chen for bulimia and binge eating disorder. Focuses on emotion regulation as a driver of binge-purge behavior.

Standalone DBT skills groups. Not a full DBT program, but skills groups on their own have evidence for building emotion regulation more generally, and are useful for a range of patients who don't need or can't access full DBT.
