Personality Disorder Statistics

Borderline personality disorder is where the stakes feel most visible, with a 35% reduction in suicidal behavior from DBT versus treatment as usual and a still startling 47% of people with any personality disorder reporting at least one substance use disorder in the NCS-R analysis. The page pulls together current, practical signals like service use, impairment, and repeat crises alongside effect sizes from key therapy trials so you can see what personality disorder is costing and what actually moves the needle.

Personality disorder is not just a clinical label, it shows up in everyday outcomes with measurable impact, including 0.62 QALYs lost per individual over the study horizon in a global burden analysis. Yet some of the sharpest patterns are also the most surprising, like 83% of outpatient DBT programs offering both individual therapy and skills groups and 47% of people with any personality disorder reporting at least one substance use disorder. Here we pull together the key statistics, from DSM-5 cluster structure to service use and therapy effects, so you can see where risk, impairment, and recovery intersect.
