Personality disorder: a new global perspective
Open accessAbstract
Personality disorder is now being accepted as an important condition in mainstream psychiatry across the world. Although it often remains unrecognized in ordinary practice, research studies have shown it is common, creates considerable morbidity, is associated with high costs to services and to society, and interferes, usually negatively, with progress in the treatment of other mental disorders. We now have evidence that personality disorder, as currently classified, affects around 6% of the world population, and the differences between countries show no consistent variation. We are also getting increasing evidence that some treatments, mainly psychological, are of value in this group of disorders. What is now needed is a new classification that is of greater value to clinicians, and the WPA Section on Personality Disorders is currently undertaking this task.

Written from the paper’s full text.
TL;DR
This review argues that personality disorder is common, costly, and under-recognized worldwide, with prevalence estimates around 6% globally and 3–10% in community samples. It calls for a new, clinically useful classification and concludes that psychological treatments show promise while drug treatments lack long-term support.
Key findings
- Recent epidemiological studies report varied prevalence: 4.4% in Great Britain (Coid et al., n=628), 14.8% in the US (Grant et al., n=43,093), and a 10-country survey (Huang et al., n=21,162) found no consistent cross-country pattern; the abstract cites around 6% globally and a 3–10% community range.
- Comorbid personality disorder predicts poorer outcomes: meta-analytic evidence from more than 60 depression studies indicates roughly double the likelihood of non-recovery, while psychosis studies show prevalence estimates from 4.5% to 100% and poorly studied outcomes.
- Economic burden estimates include £704 million per year in English health and social care costs for people with personality disorder in contact with general practitioners, rising to £7.9 billion with productivity losses; a Dutch estimate is £11,126 per patient.
- Treatment and classification: psychotropic drugs are judged to have no proven long-term value; structured team psychological approaches are suggested for borderline personality disorder and cognitive/group approaches for antisocial personality disorder, with rewards preferred over punishment; three quarters of surveyed experts favored replacing DSM-IV, and the WPA Section is developing ICD-11 proposals.
Methods
- Design: narrative global-perspective review and position paper from the WPA Section on Personality Disorders, not primary research.
- Data: summarizes three major recent epidemiological studies (Huang et al. 2009, Coid et al. 2006, Grant et al. 2004) and reviews literature on comorbidity, costs, treatment, and classification.
- Analysis: qualitative synthesis, including reference to a meta-analysis of more than 60 depression studies described as unpublished data and to systematic reviews of treatment trials.
Limitations
- Stated: epidemiological studies are few because national surveys rarely assess personality disorder and lay-interviewer assessment is difficult; cost estimates rely on service attenders and therefore do not represent the whole personality disorder population, so the true cost remains unknown.
- Stated: treatment evidence is concentrated on borderline personality disorder, with too few randomized trials for clear conclusions; evidence for other personality disorders is scant, two cluster C trials disagree, and psychosis measurement reliability and outcomes are unclear.
- Evident from the text: as a review/position piece, it relies on selected literature and some unpublished data, and the proposed dimensional factors are acknowledged to have little validity evidence so far.

The Methods (Other correlates of personality disorders) identify social role performance as a measured functioning domain. The Results (Impairments) report significantly elevated impairment among respondents with personality disorders, with associations that weaken but remain after controlling for comorbid Axis I disorders. The Discussion likewise states that comorbid Axis I disorders do not account for the functional impairments. (LLM, conf=0.91)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
