About 5.6% of U.S. adults meet criteria for borderline personality disorder at some point in their lives, based on the World Mental Health Survey. Many people also live with related conditions like PTSD and eating disorders, and this overlap can shape how often they need urgent care or inpatient treatment. This guide also reviews evidence-based therapies—including DBT, MBT, and TFP—and explains how they may reduce self-harm and suicide-related behaviors.
Key Takeaways
- 5.6% of U.S. adults meet criteria for BPD at some point in their lifetime (World Mental Health Survey-derived estimate)
- 47.0% of people with BPD have a lifetime history of PTSD
- 43% of individuals with BPD have comorbid posttraumatic stress disorder (PTSD) in a meta-analysis
- 11% of people with BPD have comorbid eating disorders
- 1 in 4 people with BPD has a lifetime history of self-harm requiring medical attention
- BPD is associated with suicide attempts: 70% of patients have at least one attempt
- BPD patients attempt suicide at a rate about 50 times higher than the general population (meta-analytic estimate)
- Dialectical behavior therapy (DBT) reduces the frequency of self-harm acts relative to comparison conditions in randomized trials (effect reported as significant in a systematic review)
- DBT reduces suicidal behavior in BPD in randomized controlled trials (positive effects summarized in a meta-analysis)
- MBT led to reduced risk of suicide-related behaviors compared with general psychiatric management in a randomized trial
- People with mental disorders had 4.5x higher health care spending than those without mental disorders in a U.S. analysis (resource utilization context for severe conditions like BPD)
- In a U.K. cohort, adults with personality disorder had markedly higher health and social care costs than the general population; BPD is a major subset of personality disorders
- Inpatient costs for personality disorder cohorts were several-fold higher than comparators in a U.K. cost analysis (includes BPD within the diagnostic spectrum)
- 2.7% of adults in the U.S. reported 12-month DSM-IV BPD in NESARC (2001–2003)
- 13.8% of patients with BPD had at least one emergency department (ED) visit in a 12-month follow-up period in a U.S. claims study
About 5.6% of Americans develop BPD over their lifetime, with high rates of PTSD, self harm, and suicide attempts.

06
Patients with BPD show higher rates of service utilization (including outpatient and inpatient care) than patients with other mental disorders in a large U.S. claims analysis
07
Outcomes such as employment impairment are significantly higher in BPD compared with controls (employment and functioning burden quantified in cohort studies)
08
Family caregivers of people with BPD report higher caregiver burden scores than caregivers of people without BPD in a comparative study (quantified differences reported)
09
1 in 5 adolescents and young adults with BPD symptoms is reported in a population survey study (youth burden quantification)
10
Borderline personality disorder is estimated to affect roughly 1–2% of the general adult population (range summary quantified in epidemiologic review)
Interpretation
Economic & System Impact Interpretation
Across multiple health systems, people with borderline personality disorder and related personality disorders consistently drive substantially higher utilization and costs, including U.S. spending that is 4.5 times higher than for those without mental disorders and U.K. inpatient and social care costs that are several-fold higher than comparators.

Dialectical behavior therapy (DBT) reduces the frequency of self-harm acts relative to comparison conditions in randomized trials (effect reported as significant in a systematic review)
02
DBT reduces suicidal behavior in BPD in randomized controlled trials (positive effects summarized in a meta-analysis)
03
MBT led to reduced risk of suicide-related behaviors compared with general psychiatric management in a randomized trial
04
TFP showed improved overall psychosocial functioning compared with structured clinical management in a randomized trial
05
General psychiatric management (GPM) is less effective than DBT for some outcomes in systematic reviews of BPD psychotherapies (comparative findings summarized as statistically significant)
06
Hospitalization length of stay was reduced by structured BPD psychotherapy programs compared with treatment as usual in a controlled study (reported as statistically significant)
07
In a network meta-analysis, structured psychotherapies (including DBT, MBT, TFP, and others) had the strongest evidence for reducing BPD symptoms compared with non-structured approaches
08
Atypical antipsychotics reduce symptoms such as anger/hostility in some BPD patients compared with placebo in randomized trials (reported in an evidence review)
Interpretation
Treatments & Effectiveness Interpretation
Across randomized trials, targeted structured psychotherapies such as DBT, MBT, and TFP show clear benefits over comparison or general management, including reduced self-harm and suicidal behavior and even shorter hospital stays, highlighting that effective BPD treatment outcomes are achievable when the therapy is specifically designed and systematically delivered.

Interpretation
Outcomes & Mortality Interpretation
From an outcomes and mortality perspective, BPD is strongly associated with severe self-harm and early death, including a 1 in 4 lifetime history of medically treated self-harm, suicide attempt rates reaching about 70 percent with attempts around 50 times higher than the general population, and an average 13.6 year reduction in life expectancy.

Interpretation
Industry Overview Interpretation
From an industry overview perspective, the high overlap of BPD with other costly and complex conditions is striking, with 47.0% having a lifetime history of PTSD and 17.9% having a substance use disorder, while pooled estimates show comorbid bipolar disorder at 27.2%, reinforcing why treatment demand and healthcare spending remain substantial as reflected in U.S. severe mental illness costs of about $67,000 per patient annually in 2013.
