Dialectical Behavior Therapy (DBT): How It Works, What It Treats, and What to Expect

Dialectical Behavior Therapy (DBT) is a structured, evidence-based form of cognitive-behavioral therapy originally developed in the late 1980s by psychologist Marsha M. Linehan. It was initially designed to treat individuals with borderline personality disorder (BPD), particularly those experiencing chronic suicidal ideation and self-harm. Since then, its applications have expanded significantly across a range of mental health conditions.

The word "dialectical" refers to the integration of opposites — specifically, the therapeutic balance between acceptance and change. This is the philosophical core of DBT: clients learn to accept themselves and their current reality as it is, while simultaneously working toward meaningful behavioral change. This dual emphasis distinguishes DBT from standard cognitive-behavioral therapy (CBT), which tends to focus more heavily on change strategies.

DBT is rooted in several theoretical frameworks:

• Cognitive-behavioral theory: The idea that thoughts, feelings, and behaviors are interconnected, and that changing maladaptive patterns leads to improved outcomes.
• Dialectical philosophy: The recognition that truth is not absolute — seemingly contradictory positions can coexist, and synthesis of opposing forces drives growth.
• Zen and contemplative practices: Mindfulness skills drawn from Eastern meditative traditions form a foundational component of the treatment.

DBT operates on a biosocial theory of emotional dysregulation, which proposes that certain individuals are biologically predisposed to heightened emotional sensitivity, stronger emotional reactions, and a slower return to emotional baseline. When this biological vulnerability interacts with an invalidating environment — one that dismisses, punishes, or ignores a person's emotional experiences — the result can be pervasive difficulties with emotion regulation, interpersonal functioning, identity, and behavioral control.

Comprehensive DBT — sometimes called "standard DBT" — is a highly structured treatment that typically includes four primary modes of delivery:

• Individual therapy: Weekly one-on-one sessions (usually 50–60 minutes) with a trained DBT therapist. These sessions focus on reviewing diary cards (daily tracking of emotions, urges, and behaviors), addressing target behaviors using a structured hierarchy, and applying DBT skills to real-life situations.
• Skills training group: Weekly group sessions (typically 2–2.5 hours) led by a trained facilitator. These groups function more like a class than traditional group therapy — the focus is on teaching and practicing the four core DBT skill modules.
• Phone coaching: Between sessions, clients can contact their individual therapist for brief, real-time coaching on how to apply DBT skills during a crisis or difficult moment. This is not traditional on-call therapy; it is specifically focused on skill generalization.
• Therapist consultation team: DBT therapists meet weekly with other DBT providers to support one another, maintain treatment fidelity, and reduce burnout. This mode is for the therapists, not the clients, but it is considered essential to the treatment model.

The four core skill modules taught in DBT are:

• Mindfulness: Often called the "core" skill, mindfulness teaches individuals to observe, describe, and participate in the present moment without judgment. Skills include distinguishing between the "reasonable mind" (logic-driven), "emotion mind" (feeling-driven), and "wise mind" (the integration of both).
• Distress Tolerance: These skills help individuals survive crises without making them worse. Techniques include the TIPP skills (Temperature, Intense exercise, Paced breathing, Progressive muscle relaxation), radical acceptance, distraction strategies, and self-soothing with the five senses.
• Emotion Regulation: This module teaches individuals to identify and label emotions, understand the function of emotions, reduce emotional vulnerability (through the ABC PLEASE skills — accumulate positive experiences, build mastery, cope ahead, treat physical illness, eat balanced meals, avoid mood-altering substances, get adequate sleep, and exercise), and change unwanted emotions using opposite action.
• Interpersonal Effectiveness: These skills address how to ask for what you need, say no, and maintain self-respect in relationships. Key acronyms include DEAR MAN (for objective effectiveness), GIVE (for relationship effectiveness), and FAST (for self-respect effectiveness).

A full course of standard DBT typically lasts approximately one year, though the specific duration varies depending on the individual's needs, the severity of target behaviors, and the treatment setting. The skills training group cycles through all four modules, usually completing two full rounds during the treatment year.

DBT was originally developed for — and has the strongest evidence base in — the treatment of borderline personality disorder (BPD). According to the DSM-5-TR, BPD is characterized by a pervasive pattern of instability in interpersonal relationships, self-image, and affect, along with marked impulsivity. The DSM-5-TR estimates the prevalence of BPD at approximately 1.6% of the general population, though some estimates suggest it may be as high as 5.9%. DBT is widely considered the first-line psychotherapeutic treatment for this condition.

Beyond BPD, DBT has been adapted for and studied in a range of other conditions:

• Chronic suicidal ideation and self-harm: DBT has robust evidence for reducing suicidal behavior and non-suicidal self-injury (NSSI), regardless of specific diagnosis.
• Substance use disorders: DBT-SUD (Substance Use Disorder) is an adapted protocol that integrates standard DBT with addiction-specific interventions, including attachment strategies and dialectical abstinence.
• Eating disorders: Research supports DBT's effectiveness for binge eating disorder and bulimia nervosa, particularly when these conditions involve significant emotion dysregulation.
• Post-traumatic stress disorder (PTSD): DBT-PE (Prolonged Exposure) integrates trauma processing with standard DBT for individuals with co-occurring BPD and PTSD.
• Treatment-resistant depression: Emerging research suggests DBT skills, particularly emotion regulation and behavioral activation components, can benefit individuals with chronic or treatment-resistant major depressive disorder.
• Attention-deficit/hyperactivity disorder (ADHD) in adults: Some adapted DBT programs address emotional dysregulation associated with ADHD.
• Adolescent populations: DBT-A (Adolescents) is a modified version that shortens treatment duration, simplifies language, and includes family members in the skills training group.

Notably, DBT is not appropriate for every individual or every condition. The treatment is intensive and requires a significant time commitment. It is most indicated when emotional dysregulation is a primary driver of functional impairment, particularly when that dysregulation manifests in behavioral patterns such as self-harm, suicidality, substance misuse, or chaotic interpersonal relationships.

Beginning DBT typically starts with an orientation and commitment phase. Before formal treatment begins, the therapist and client discuss the nature of DBT, what it requires, and whether the client is willing to commit to the treatment structure. This includes agreeing to attend weekly individual sessions and skills group, reduce life-threatening behaviors, reduce therapy-interfering behaviors, and work on improving quality of life. This mutual commitment — from both client and therapist — is a distinctive feature of the model.

Once treatment begins, individual sessions follow a structured target hierarchy:

• First priority: Life-threatening behaviors (suicidal ideation, self-harm, homicidal urges)
• Second priority: Therapy-interfering behaviors (missing sessions, not completing diary cards, behaviors that damage the therapeutic relationship)
• Third priority: Quality-of-life-interfering behaviors (substance use, housing instability, untreated medical conditions, relationship crises)
• Fourth priority: Behavioral skills acquisition (learning and applying new skills)

Clients complete diary cards daily — these are structured logs that track emotions, urges (such as urges to self-harm or use substances), and the use of specific DBT skills. Diary cards are reviewed at the beginning of each individual session and guide the session's focus.

Skills group functions differently from process-oriented group therapy. Members are not expected to share deeply personal content or provide feedback to one another about interpersonal dynamics. Instead, the group leader teaches skills through didactic instruction, guided practice, and homework assignments. Participants practice skills through role-plays, worksheets, and between-session exercises.

DBT is emotionally demanding work. Clients should expect to confront painful patterns, tolerate uncomfortable emotions without resorting to habitual escape behaviors, and practice new skills even when they feel unnatural. Therapists in DBT balance warmth and validation with direct, sometimes confrontational, feedback about behavior patterns. This balance — acceptance and change — runs through every aspect of the treatment.

It is also worth noting that DBT therapists use a non-pejorative, behaviorally specific language. Rather than labeling a client as "manipulative" or "attention-seeking," DBT conceptualizes problematic behaviors as learned solutions to unbearable emotional pain. This framework reduces shame and opens space for behavioral change.

DBT is one of the most extensively researched psychotherapies for personality disorders and suicidal behavior. It meets criteria for an empirically supported treatment according to standards set by the American Psychological Association's Division 12 (Society of Clinical Psychology).

Key findings from the research literature include:

• Reduction in suicidal behavior: Multiple randomized controlled trials (RCTs) have demonstrated that DBT significantly reduces suicide attempts, suicidal ideation, and non-suicidal self-injury compared to treatment as usual. Linehan's landmark 2006 RCT published in the Archives of General Psychiatry found that DBT reduced suicide attempts by approximately 50% compared to community treatment by experts.
• Reduction in self-harm: Across studies, DBT consistently produces significant reductions in the frequency and medical severity of self-harm episodes.
• Decreased hospitalization: Research consistently shows that DBT reduces psychiatric emergency room visits and inpatient hospitalizations, which has significant implications for both patient well-being and healthcare costs.
• Improved emotion regulation: Clients completing DBT demonstrate measurable improvements in emotion regulation capacity, as well as reductions in anger, depression, and anxiety symptoms.
• Treatment retention: DBT has notably lower dropout rates than many other treatments for BPD. Research suggests completion rates of approximately 60–75% in standard DBT programs, compared to significantly higher dropout rates in unstructured treatments for the same population.
• Substance use outcomes: Studies of DBT-SUD have found reductions in substance use and improved treatment retention in individuals with co-occurring BPD and substance use disorders.

A 2021 Cochrane review of psychological therapies for borderline personality disorder identified DBT as having a strong evidence base, though the reviewers noted that more large-scale, multi-site trials are needed. Research also supports the effectiveness of DBT-A for suicidal and self-harming adolescents, with a notable 2014 RCT published in the Journal of the American Academy of Child & Adolescent Psychiatry demonstrating significant reductions in self-harm and suicidal ideation in teens receiving DBT-A compared to enhanced usual care.

It is important to acknowledge that while the evidence for DBT in BPD is robust, the evidence for some of its newer adaptations — such as for ADHD, chronic depression, and certain eating disorders — is still emerging and less definitive. Additionally, most DBT research has been conducted in specialized academic settings, and questions remain about how well outcomes generalize to community practice settings with fewer resources and less intensive clinician training.

While DBT is a powerful treatment, it is not without limitations, and it is not the right fit for every person or clinical situation.

• Time and commitment: Standard comprehensive DBT requires attending both individual therapy and a weekly skills group, completing daily diary cards, and potentially engaging in between-session phone coaching. This amounts to a substantial weekly time investment — often 4 or more hours per week when including homework — that can be challenging to sustain, especially for individuals juggling work, school, or caregiving responsibilities.
• Emotional intensity: DBT asks clients to directly confront painful emotions and reduce reliance on avoidance or escape behaviors. This can initially feel destabilizing, and some individuals may experience a temporary increase in distress as they begin applying new strategies.
• Not a standalone trauma treatment: While DBT builds emotional regulation capacity that can be essential for trauma processing, standard DBT does not include formal trauma-focused interventions. Individuals with PTSD may need additional or integrated trauma treatment (such as DBT-PE or subsequent evidence-based trauma therapy).
• Availability of comprehensive programs: True comprehensive DBT — with all four modes — is not available in all areas. Many clinicians describe their approach as "DBT-informed" or offer only some components (such as individual therapy with DBT techniques or standalone skills groups). While these can be helpful, they are not equivalent to the full model, and the evidence base primarily supports comprehensive DBT.
• Group setting not suitable for all: Some individuals find the group skills training component difficult due to social anxiety, scheduling constraints, or past negative experiences in group settings. While the group is a core component, some providers offer individual skills training as an alternative, though this deviates from the standard model.
• Cultural considerations: DBT was developed in a Western, predominantly white, academic context. While research increasingly includes diverse populations, some scholars have noted that certain concepts — such as the emphasis on individual emotion regulation — may need cultural adaptation to be maximally relevant for collectivist cultures or communities where systemic invalidation (racism, poverty, discrimination) plays a significant role in emotional distress.

It is also worth noting that DBT is not designed to be a lifelong treatment. The goal is skill acquisition and behavioral change that eventually allows the individual to manage independently. Some individuals benefit from periodic "booster" sessions or skills refresher groups after completing a full course of treatment.

Finding a properly trained DBT provider requires some due diligence, as the term "DBT" is used loosely in clinical practice. Here are key steps and considerations:

• DBT-Linehan Board of Certification: The most rigorous credential is certification through the DBT-Linehan Board of Certification (DBT-LBC). Clinicians and programs that hold this certification have undergone extensive training and demonstrated adherence to the comprehensive DBT model. The DBT-LBC maintains a searchable directory on their website.
• Behavioral Tech, LLC: Founded by Marsha Linehan, Behavioral Tech provides intensive DBT training to clinicians. Their website includes a directory of trained providers, though training alone does not guarantee current practice fidelity.
• Ask specific questions: When evaluating a potential provider, ask directly: Do you offer comprehensive DBT with all four modes (individual therapy, skills group, phone coaching, and consultation team)? What DBT training have you completed? Do you use diary cards and follow the treatment target hierarchy? These questions can help distinguish between comprehensive DBT and "DBT-informed" approaches.
• University and medical center programs: Academic medical centers and university training clinics often offer comprehensive DBT programs, sometimes at reduced cost through training clinics staffed by supervised doctoral students or postdoctoral fellows.
• Community mental health centers: Some publicly funded mental health agencies have implemented comprehensive DBT programs, particularly for individuals with BPD, chronic suicidality, or co-occurring substance use disorders.
• Telehealth options: The expansion of telehealth has increased access to DBT. Some comprehensive DBT programs now offer individual sessions and skills groups via videoconference, which can be especially valuable for individuals in rural or underserved areas.

If comprehensive DBT is not available in your area, a DBT skills group combined with individual therapy from a clinician trained in DBT principles can still be beneficial, though outcomes may differ from those seen in research on the comprehensive model.

DBT can be expensive, and accessibility remains a significant challenge for many individuals who could benefit from it.

Cost estimates: In the United States, weekly individual DBT sessions typically range from $150 to $300 per session, depending on the provider's credentials, geographic location, and whether the provider is in-network with insurance. Skills groups may cost an additional $50 to $150 per session. Over the course of a year-long comprehensive program, total out-of-pocket costs can be substantial.

Insurance coverage: Many private insurance plans and Medicaid programs cover individual therapy sessions with a licensed provider who uses DBT. However, coverage for skills groups varies widely. Some insurers classify DBT skills groups as "group therapy" and cover them accordingly; others do not cover them at all or consider them educational rather than therapeutic. It is essential to verify coverage with your specific plan.

Strategies for reducing cost:

• University and training clinics: Doctoral training programs and postdoctoral training sites often offer comprehensive DBT at significantly reduced rates, with services provided by supervised trainees.
• Sliding scale providers: Some private practitioners offer sliding scale fees based on income.
• Community mental health centers: Publicly funded agencies may offer DBT at low or no cost, particularly for individuals with Medicaid or who are uninsured.
• Self-guided skills resources: While not a substitute for comprehensive treatment, Linehan's DBT Skills Training Handouts and Worksheets (second edition) is widely available and can supplement therapy. Several evidence-informed apps and workbooks also teach DBT skills, which can be useful for individuals on waitlists or unable to access formal programs.
• Online programs: Some organizations offer structured online DBT skills courses at lower cost than in-person programs. While research on the effectiveness of purely online DBT is still developing, preliminary evidence suggests that technology-assisted delivery can improve access without significantly compromising skill acquisition.

Waitlists for comprehensive DBT programs can be long — sometimes several months. If you are experiencing a mental health crisis while waiting for DBT, contact a crisis resource such as the 988 Suicide and Crisis Lifeline (call or text 988 in the United States) for immediate support.

DBT is not the only evidence-based treatment for emotional dysregulation, personality disorders, or the conditions it addresses. Depending on an individual's specific presentation, needs, and preferences, other treatments may be appropriate:

• Mentalization-Based Treatment (MBT): Developed by Peter Fonagy and Anthony Bateman, MBT focuses on improving the capacity to understand one's own and others' mental states (thoughts, feelings, intentions). It has strong evidence for BPD, particularly in reducing self-harm and improving interpersonal functioning.
• Schema Therapy: Developed by Jeffrey Young, schema therapy integrates cognitive-behavioral, attachment, and experiential techniques to address deep-rooted maladaptive patterns ("schemas") that develop in childhood. RCTs support its effectiveness for BPD and other personality disorders.
• Transference-Focused Psychotherapy (TFP): A psychodynamic treatment for BPD that focuses on the patient-therapist relationship as a vehicle for understanding and changing internalized patterns of relating to self and others. Research supports its efficacy for BPD.
• Cognitive Behavioral Therapy (CBT): Standard CBT is effective for many of the conditions DBT also addresses, including depression, anxiety, and eating disorders. However, standard CBT may be less effective for individuals whose primary difficulties involve severe emotional dysregulation or chronic suicidality.
• Acceptance and Commitment Therapy (ACT): ACT shares DBT's emphasis on acceptance and mindfulness but takes a distinct approach, focusing on psychological flexibility, values clarification, and committed action. ACT has a growing evidence base for depression, anxiety, chronic pain, and substance use.
• Systems Training for Emotional Predictability and Problem Solving (STEPPS): A group-based treatment for BPD that is shorter than standard DBT (typically 20 weeks) and designed to be used as an adjunct to existing individual therapy. Research supports its effectiveness in reducing BPD symptoms.
• Medication: While no medication is specifically FDA-approved for BPD, pharmacotherapy can play a supportive role in managing co-occurring symptoms such as depression, anxiety, impulsivity, or psychotic-like features. Medication decisions should be made in collaboration with a psychiatrist who understands the complex relationship between personality pathology and pharmacological intervention.

The best treatment approach depends on the individual's specific symptoms, goals, treatment history, and practical circumstances. A thorough evaluation by a qualified mental health professional is the most reliable way to determine which treatment — or combination of treatments — is most appropriate.

If you recognize patterns in yourself that are consistent with the difficulties DBT was designed to address, seeking a professional evaluation is an important step. Consider reaching out to a mental health provider if you experience:

• Intense, rapidly shifting emotions that feel overwhelming or uncontrollable
• Recurrent urges to harm yourself or thoughts of suicide
• A pattern of unstable, intense, or chaotic relationships
• Chronic feelings of emptiness or unclear sense of identity
• Impulsive behaviors that consistently create problems in your life (substance use, reckless spending, binge eating, unsafe sexual behavior)
• Difficulty recovering emotionally from interpersonal conflicts or perceived rejection
• A history of treatment that hasn't adequately addressed emotional dysregulation

If you are in immediate danger or experiencing a mental health crisis, contact the 988 Suicide and Crisis Lifeline by calling or texting 988, go to your nearest emergency room, or call 911.

A licensed mental health professional — such as a clinical psychologist, licensed clinical social worker, or psychiatrist — can conduct a comprehensive evaluation and determine whether DBT or another evidence-based treatment is appropriate for your situation. You do not need a formal diagnosis to begin exploring treatment options, and seeking help is a sign of strength, not weakness.
