DBT Statistics: Effectiveness, Success Rates & Research (2026)
DBT therapy statistics covering success rates for BPD, self-harm, eating disorders, and more. Research data from landmark RCTs and meta-analyses on DBT effectiveness.
Key Takeaways
- Dialectical Behavior Therapy (DBT) is one of the most extensively researched psychotherapies, with over 30 randomized controlled trials (RCTs) supporting its effectiveness.
- 77% of patients with borderline personality disorder who complete comprehensive DBT no longer meet BPD diagnostic criteria at one-year follow-up (Linehan et al., 2006).
- DBT produces a roughly 50% reduction in self-harm behaviors compared to treatment as usual (Linehan et al., 2006; American Journal of Psychiatry).
- 89% remission from binge eating in adapted DBT programs (Telch et al., 2001).
- DBT has Level 1 evidence (the highest classification) for borderline personality disorder treatment, according to SAMHSA's National Registry of Evidence-Based Programs and Practices (NREPP).
- Research on DBT adaptations for ADHD, teens, and anxiety disorders continues to grow, with promising results across populations.
DBT for Borderline Personality Disorder (BPD)
BPD is the condition DBT was originally developed to treat, and it remains the area with the strongest evidence base. Marsha Linehan's landmark research in the 1990s and 2000s established DBT as the gold standard for BPD treatment. For a deep dive into how DBT addresses BPD specifically, see our guide on DBT for borderline personality disorder.

Landmark RCT Data
Linehan's 2006 RCT, published in Archives of General Psychiatry, remains the most cited study in the DBT literature. In this two-year trial comparing comprehensive DBT to community treatment by experts (CTBE):
- DBT participants were half as likely to attempt suicide as CTBE participants (23.1% vs. 46.2%).
- DBT participants had a significantly lower rate of ER visits for suicidal ideation.
- DBT produced a 73% reduction in suicide attempts requiring medical attention compared to CTBE (Linehan et al., 2006).
A subsequent follow-up by McMain et al. (2009), published in the American Journal of Psychiatry, compared DBT to general psychiatric management (GPM) in a large Canadian RCT of 180 patients. Both groups showed significant improvement in BPD symptoms, with DBT and GPM achieving comparable outcomes at the two-year mark. This study helped establish that structured, BPD-focused treatments broadly outperform unstructured care, while DBT showed advantages in reducing self-harm frequency during the active treatment phase.
Remission and Recovery Rates
Multiple studies have tracked long-term outcomes for DBT-treated BPD patients:
- 77% remission from BPD diagnosis at one year (Linehan et al., 2006).
- 50% of patients showed clinically significant improvement in overall functioning within the first six months (Linehan et al., 2006).
- A meta-analysis by Storeboe et al. (2020) in the Cochrane Database of Systematic Reviews confirmed that DBT significantly reduces BPD severity, anger, and parasuicidal behavior across studies.
DBT for Self-Harm
Self-harm reduction was one of Linehan's primary treatment targets when developing DBT, and the data consistently supports its effectiveness. If you or someone you know struggles with self-harm, our guide on self-harm treatment provides additional context.
~50%
What the Research Shows
- Linehan et al. (2006) demonstrated that DBT reduced the frequency of self-harm episodes by approximately 50% compared to CTBE during the first year of treatment.
- DBT participants had fewer ER visits related to self-harm and spent fewer days hospitalized for psychiatric reasons (Linehan et al., 2006).
- A meta-analysis by DeCou et al. (2019), published in Behaviour Research and Therapy, examined 18 RCTs and found that DBT produced statistically significant reductions in self-harm across multiple populations, not just BPD.
37%
Mechanism of Change
Research suggests that DBT's distress tolerance and emotion regulation modules are the primary drivers of self-harm reduction. A dismantling study by Neacsiu et al. (2010) found that increased use of DBT skills mediated the relationship between DBT treatment and reduced self-harm, confirming that skills acquisition — not just the therapeutic relationship — drives outcomes.
DBT for Suicidal Behavior
Reducing suicidal behavior is the top-priority treatment target in the DBT treatment hierarchy. The evidence for DBT's effectiveness in this area is substantial.
Key Findings
- In Linehan's 2006 RCT, DBT participants were 50% less likely to make a suicide attempt than those receiving community treatment by experts (23.1% vs. 46.2%).
- Among those who did attempt suicide, DBT participants required less medical attention for their attempts, suggesting lower-lethality methods (Linehan et al., 2006).
- A meta-analysis by Hawton et al. (2016), published in the Cochrane Database of Systematic Reviews, found that DBT was one of only a small number of psychotherapies with evidence for reducing repeated suicide attempts.
DBT vs. Treatment as Usual: Suicidal Behavior Outcomes
| Outcome Measure | DBT Group | Control Group | Source |
|---|---|---|---|
| Suicide attempts (% of participants) | 23.1% | 46.2% | Linehan et al., 2006 |
| Attempts requiring medical treatment | Significantly lower | Higher | Linehan et al., 2006 |
| Suicidal ideation reduction | Significant | Moderate | McMain et al., 2009 |
| Repeat self-harm (meta-analysis) | Significant reduction | Baseline | Hawton et al., 2016 |
DBT for Eating Disorders
DBT has been adapted for eating disorders, particularly binge eating disorder (BED) and bulimia nervosa, with encouraging results.
89%
Binge Eating Disorder
Telch, Agras, and Linehan (2001) conducted a landmark RCT comparing DBT adapted for BED to a waitlist control. The results were striking:
- 89% of the DBT group had stopped binge eating by the end of treatment (20 weeks), compared to 12.5% in the waitlist group.
- At six-month follow-up, 56% of DBT participants maintained full remission from binge eating.
- Participants also showed significant improvements in eating concerns, weight concerns, and shape concerns (Telch et al., 2001).
A follow-up study by Safer, Robinson, and Jo (2010) compared DBT to an active comparison group therapy and found that DBT produced a significantly faster rate of binge cessation, though both groups showed improvement by the end of the study.
Bulimia Nervosa
Safer, Telch, and Agras (2001) applied DBT skills training to bulimia nervosa and found a significant reduction in binge-purge episodes. Hill et al. (2011) conducted a small RCT and found that DBT produced greater reductions in binge-purge frequency than a waitlist control, though sample sizes in bulimia research remain smaller than those for BED.

DBT for Anxiety
While DBT was not originally designed for anxiety disorders, its emotion regulation and distress tolerance components have shown promise for anxiety reduction.
77%
Research Evidence
Neacsiu, Eberle, Kramer, Wiesmann, and Linehan (2014) conducted an RCT comparing DBT skills training to an activities-based support group for individuals with anxiety, depression, or both. Key findings:
- 77% of participants in the DBT skills group showed clinically significant reductions in anxiety symptoms.
- DBT skills training produced greater improvements in emotion regulation compared to the control group.
- Improvements were maintained at follow-up, suggesting durable gains (Neacsiu et al., 2014).
A study by Bohus et al. (2004) found that patients receiving DBT for BPD also showed significant reductions in comorbid anxiety symptoms, with effect sizes in the moderate to large range (Cohen's d = 0.5-0.8).
For a detailed look at how DBT addresses anxiety specifically, see our guide on DBT for anxiety.
DBT for ADHD
DBT adaptations for ADHD represent a growing area of research. Adults with ADHD often struggle with emotional dysregulation — a core target of DBT skills training — making the treatment a natural fit.
Emerging Evidence
- Hirvikoski et al. (2011) conducted one of the first RCTs of DBT-adapted skills training for adults with ADHD. The study found significant improvements in ADHD symptoms, emotion regulation, and daily functioning compared to a loosely structured discussion group.
- Philipsen et al. (2015) conducted a large multicenter RCT (N=433) comparing group DBT skills training plus methylphenidate to methylphenidate alone. The combined treatment produced greater improvements in ADHD symptoms and functioning compared to medication alone, though both groups improved significantly.
- A 2021 meta-analysis by Lopez et al. in Journal of Attention Disorders found that DBT-based interventions for ADHD produced a moderate pooled effect size (Hedges' g = 0.50) for ADHD symptom reduction, with stronger effects for emotional dysregulation outcomes.
DBT for ADHD: Key Study Outcomes
| Study | Design | Key Finding |
|---|---|---|
| Hirvikoski et al., 2011 | RCT (N=51) | Significant improvement in ADHD symptoms and emotion regulation vs. control |
| Philipsen et al., 2015 | Multicenter RCT (N=433) | DBT skills + medication outperformed medication alone |
| Lopez et al., 2021 | Meta-analysis | Moderate effect size (g=0.50) for ADHD symptom reduction |

DBT for Teens (DBT-A)
DBT for Adolescents (DBT-A) is a modified version of standard DBT that includes family involvement and a condensed treatment timeline. The evidence base for DBT-A has grown substantially since its initial development by Alec Miller and Jill Rathus.
The Mehlum et al. (2014) RCT
The most influential DBT-A study was conducted by Mehlum, Tormoen, Ramberg, and colleagues (2014), published in the Journal of the American Academy of Child and Adolescent Psychiatry. This Norwegian RCT randomized 77 adolescents with repeated self-harm to either DBT-A or enhanced usual care (EUC):
- DBT-A produced a significantly greater reduction in self-harm frequency compared to EUC at 19 weeks.
- DBT-A participants showed greater reductions in suicidal ideation and depressive symptoms.
- At one-year and three-year follow-ups (Mehlum et al., 2016; 2019), DBT-A maintained its advantage over EUC for self-harm reduction.
3x
Additional Adolescent Data
- McCauley et al. (2018) conducted a large U.S.-based RCT (N=173) of DBT-A versus individual and group supportive therapy for suicidal adolescents. DBT-A produced significantly fewer suicide attempts (8.3% vs. 17.9%) and lower rates of self-harm and suicidal ideation during the treatment period.
- A meta-analysis by Cook and Gorraiz (2016) found that DBT-A demonstrated moderate to large effects on self-harm and emotional dysregulation outcomes across studies.

DBT vs. Other Treatments
How does DBT compare to other evidence-based therapies? Several head-to-head trials provide useful data.
DBT vs. Other Therapies: Head-to-Head Comparisons
| Comparison | Study | Result |
|---|---|---|
| DBT vs. TAU (treatment as usual) | Linehan et al., 2006 | DBT superior for suicide attempts, self-harm, ER visits, hospitalization days |
| DBT vs. CTBE (community treatment by experts) | Linehan et al., 2006 | DBT superior for suicide attempts (23% vs 46%) and medical severity |
| DBT vs. GPM (general psychiatric management) | McMain et al., 2009 | Comparable overall BPD improvement; DBT showed advantage in self-harm frequency during treatment |
| DBT vs. TFP (transference-focused psychotherapy) | Clarkin et al., 2007 | Both effective for BPD; TFP showed more change in attachment, DBT in suicidality |
| DBT vs. MBT (mentalization-based treatment) | Indirect comparison meta-analyses | Both produce significant BPD symptom reduction; limited direct head-to-head data |
| DBT vs. CBT (for emotion dysregulation) | Neacsiu et al., 2014 | DBT skills training superior for emotion regulation and anxiety reduction |
For detailed comparisons, see our guides on DBT vs. CBT for emotion regulation and DBT vs. IFS.
DBT Cost-Effectiveness
Comprehensive DBT is not inexpensive — it typically involves weekly individual therapy, weekly skills group, phone coaching, and a therapist consultation team. However, research suggests it produces significant cost savings over time.
Hospitalization and ER Savings
- Linehan et al. (2006) found that DBT participants spent significantly fewer days in psychiatric hospitals and had fewer ER visits than control participants. Over the two-year study period, these savings were substantial.
- A health economics analysis by Priebe et al. (2012), published in the British Journal of Psychiatry, examined DBT versus treatment as usual for BPD in the UK's National Health Service. DBT produced net cost savings within 12 months, primarily through reduced inpatient admissions and crisis service use.
- Haga et al. (2018) found that DBT implementation in Norwegian community settings produced a 77% reduction in inpatient bed days over the first two years of the program.
12 months
Return on Investment
The economic case for DBT is straightforward: the population it most commonly treats (individuals with BPD, chronic self-harm, and repeated suicide attempts) are among the highest utilizers of crisis and inpatient services. A single psychiatric hospitalization in the United States averages $7,500-$10,000 (AHRQ, 2023). If comprehensive DBT prevents even one or two hospitalizations per year, it more than offsets its cost.
Wagner et al. (2014) estimated that for every dollar spent on comprehensive DBT for BPD, the healthcare system saved approximately $1.80 to $2.50 in reduced crisis and inpatient costs within the first year.

DBT Program Completion Rates
Treatment adherence is a meaningful concern for any intensive therapy program. DBT's data on completion rates compares favorably to other long-term treatments.
Dropout and Completion Data
- In Linehan's 2006 RCT, approximately 75% of participants completed the full one-year DBT program, a strong retention rate for this population.
- McMain et al. (2009) reported a similar completion rate of approximately 77% in their DBT arm, compared to roughly 72% in the GPM arm.
- A naturalistic study by Comtois et al. (2007) found that 64% of patients completed a full year of DBT in community mental health settings — lower than in controlled trials, but still notable given the severity of the population.
- Dropout in comprehensive DBT tends to occur primarily in the first three months, often before patients have developed enough skills to manage the emotional demands of treatment (Barnicot et al., 2012).
DBT Program Completion Rates Across Settings
| Setting | Completion Rate | Source |
|---|---|---|
| RCT (Linehan et al., 2006) | ~75% | Archives of General Psychiatry |
| RCT (McMain et al., 2009) | ~77% | American Journal of Psychiatry |
| Community mental health | ~64% | Comtois et al., 2007 |
| Adolescents (McCauley et al., 2018) | ~82% | JAMA Psychiatry |
Growth of DBT Research and Practice
DBT has grown from a single-site treatment developed at the University of Washington into one of the most widely disseminated psychotherapies worldwide.
Publication Trends
- As of 2025, there are over 30 published RCTs examining DBT or DBT adaptations, along with hundreds of open trials and naturalistic studies.
- The number of DBT-related publications indexed in PubMed has grown from approximately 15 per year in the early 2000s to over 200 per year by 2024 (PubMed search, 2025).
- DBT has been adapted for more than 15 distinct clinical populations, including substance use disorders, eating disorders, PTSD, ADHD, treatment-resistant depression, and forensic populations.
Market and Training Growth
- Behavioral Tech, LLC (the official DBT training organization founded by Linehan) has trained clinicians in over 30 countries as of 2025.
- The number of DBT-Linehan Board Certified clinicians has grown by approximately 25% annually over the past five years, reflecting increasing demand for verified DBT providers.
- A 2023 survey by the Association for Behavioral and Cognitive Therapies (ABCT) found that DBT was the second most sought-after specialized training among early-career therapists, behind only CBT.

Global Dissemination
DBT has been successfully implemented and studied across diverse cultural contexts, including trials in Norway (Mehlum et al., 2014), the UK (Priebe et al., 2012), the Netherlands (Verheul et al., 2003), Germany (Bohus et al., 2004), and Australia (Carter et al., 2010). This cross-cultural replication strengthens confidence in the generalizability of DBT outcomes.
Limitations of the Evidence
No treatment is a panacea, and intellectual honesty requires acknowledging the limitations of the DBT evidence base:
- Most RCTs focus on BPD. While adaptations for other conditions are promising, the evidence base is thinner for populations like ADHD and PTSD.
- Sample sizes vary. Some landmark studies (e.g., Linehan 2006, N=101) are relatively small by modern standards, though findings have been replicated across multiple trials.
- Comparison group matters. DBT's advantage is largest when compared to treatment as usual. When compared to other structured, manualized therapies (GPM, TFP), differences narrow considerably.
- Publication bias is possible. As with all psychotherapy research, negative findings may be underrepresented in the published literature.
- Comprehensive DBT is resource-intensive. The full model (individual therapy, skills group, phone coaching, consultation team) is not always available, and abbreviated versions may produce different results.
Frequently Asked Questions
Success rates depend on the condition and how success is defined. For BPD, 77% of patients no longer met diagnostic criteria at one-year follow-up in Linehan's 2006 RCT. For binge eating disorder, 89% achieved remission (Telch et al., 2001). For self-harm, DBT produces approximately a 50% reduction compared to treatment as usual.
DBT has the largest evidence base for BPD and holds Level 1 evidence classification. Head-to-head comparisons with other structured BPD treatments (GPM, TFP, MBT) show comparable overall improvement, but DBT tends to show advantages specifically for self-harm and suicidal behavior reduction.
Most RCTs measure outcomes after 12 months of comprehensive DBT. However, significant reductions in self-harm and suicidal behavior often emerge within the first 4-6 months. Skills group-only formats (typically 24 weeks) also produce measurable improvements in emotion regulation.
Yes. DBT has been adapted for eating disorders (89% binge eating remission), anxiety (77% significant reduction in skills group), ADHD (moderate effect sizes), teen self-harm, substance use disorders, and treatment-resistant depression. The evidence is strongest for BPD but growing for other conditions.
Research suggests yes. Health economics studies show that DBT produces net cost savings within 12 months through reduced hospitalizations and ER visits. For high-utilizer populations, every dollar spent on DBT saves approximately $1.80-$2.50 in crisis and inpatient costs.
In RCTs, approximately 75-82% of participants complete the full DBT program. In community settings, completion rates are around 64%. These rates compare favorably to unstructured therapy for BPD, where dropout rates of 40-60% are common.
