Personality Disorders

Personality Disorders (DSM-5-TR)

Enduring patterns of inner experience and behavior that deviate from cultural expectations, are pervasive and inflexible, and cause distress or impairment. Recommendations must be matched to the specific diagnosis, presentation and treatment goals; the assessment below has a defined borderline personality disorder population.

Prevalence: ~8% globally and ~9.6% in high-income countries (Winsper et al., 2020, meta-analysis); ~40-60% of clinical populations

Clinical Picture

Personality disorders, particularly borderline, narcissistic, and avoidant, represent some of the most challenging and most rewarding clinical work. These are not acute symptoms that developed in response to a specific stressor but enduring patterns of experiencing self and others that developed early and have become the water the client swims in. The diagnostic label itself is controversial: 'personality disorder' can pathologize adaptations that made sense in context, and the 'Cluster B' stigma in clinical settings is well-documented. The most clinically useful framing may be characterological patterns that cause suffering and that the client wants to understand and potentially change.

Treatment Considerations

For borderline personality disorder, NICE CG78 asks clinicians to consider treatment preferences, impairment, engagement and available support, and to provide information about treatment options and their evidence. It calls for structured care and therapist supervision. Its recommendation 1.3.4.5 says to consider a comprehensive DBT programme for women with BPD when reducing recurrent self-harm is a priority. This specific recommendation is not a ranking of therapies for all personality disorders and does not imply that other populations cannot benefit.


Approaches and Evidence

Of 24 associated approaches, 12 have completed assessments for this topic, 0 have source checks awaiting assessment, and 12 have neither recorded yet. Each completed assessment states its population and rationale; source checks alone do not establish effectiveness. These categories describe different findings and review stages; they are not a ranking of treatments.

Guideline recommendation (5)

These assessments record a guideline recommendation for the stated population. Read the scope and rationale; a broad topic label does not make a recommendation applicable to everyone.

Cognitive-Behavioral

Dialectical Behavior Therapy

Marsha Linehan · 1993

Reviewed population: Women with borderline personality disorder for whom reducing recurrent self-harm is a priority, receiving a comprehensive DBT programme. This is the exact population and treatment scope of NICE CG78 (2009) recommendation 1.3.4.5.

NICE CG78 (2009) recommendation 1.3.4.5 says to consider a comprehensive DBT programme for women with BPD when reducing recurrent self-harm is a priority. This is a qualified “consider” recommendation, not a strong recommendation for every BPD presentation or personality disorder. It does not separately grade standalone DBT skills, DBT-A or suicide prevention across diagnoses. The narrow assessment does not imply that people outside this source population cannot benefit; their evidence requires its own review.

Mentalization-Based Treatment

Fonagy / Bateman · 2004

Reviewed population: Adults with borderline personality disorder receiving protocol-based mentalization-based treatment.

The Dutch 2022 guideline recommends MBT among specialist BPD treatments, delivered as studied. Bateman and Fonagy (2009) randomized 134 patients to 18-month outpatient MBT or structured clinical management. Both improved; MBT showed steeper reductions in several problems, including suicide attempts and hospitalization. The primary endpoint combined suicidal behavior, severe self-injury and hospitalization. This record does not generalize to all personality disorders or prove reduced suicide mortality.

Cognitive-Behavioral

Schema Therapy

Jeffrey Young · 1990

Reviewed population: Adults with borderline personality disorder receiving schema therapy; trial findings distinguish combined individual/group from predominantly group delivery.

The Dutch 2022 guideline names schema therapy among recommended specialist BPD treatments. In Arntz et al. (2022), 495 adults were randomized across schema-therapy formats and optimal usual care; combined individual/group treatment reduced BPD severity more than predominantly group treatment or usual care. The 2026 BOOTS superiority trial of 204 outpatients found no significant difference between combined-format schema therapy and DBT in BPD-severity change or secondary outcomes. A nonsignificant superiority test does not establish equivalence. These findings should not be generalized across formats or personality-disorder subtypes.

Transference-Focused Psychotherapy

Otto Kernberg · 1999

Reviewed population: Adults with borderline personality disorder receiving manualized transference-focused psychotherapy.

The Dutch 2022 guideline names TFP among recommended BPD treatments. Clarkin et al. (2007) randomized 90 patients to yearlong TFP, DBT or dynamic supportive treatment, with medication when indicated. All groups improved on depression, anxiety, functioning and social adjustment; TFP was associated with change across additional measured domains. Within-treatment significance does not establish superiority over another active treatment. This assessment does not extend to every personality-disorder subtype.

Intensive Short-Term Dynamic Psychotherapy

Habib Davanloo · 1980

Reviewed population: Adults with DSM-IV personality disorders in the 27-person Abbass et al. (2008) trial.

ISTDP was randomized against minimal-contact delayed treatment. Symptoms and interpersonal problems improved more with ISTDP during the controlled phase. Subsequent follow-up combined participants after controls also received treatment, so diagnostic reductions at follow-up are not randomized between-group effects. The small preliminary trial does not establish results for every PD subtype or superiority over an active psychotherapy.

Radically Open Dialectical Behavior Therapy

Thomas Lynch · 2018

Reviewed population: Adults with treatment-refractory depression and comorbid obsessive-compulsive personality disorder in a secondary analysis of the RefraMED randomized trial (117-person OCPD subgroup).

RO-DBT plus usual care was compared with usual care. At 12 months, the OCPD subgroup showed better emotional approach coping and psychological flexibility, but no significant differences in depression or interpersonal functioning. This is a secondary randomized-trial analysis of comorbid OCPD, not a dedicated trial establishing OCPD remission, effectiveness across PDs, or equivalence of effects across diagnostic groups.

Supportive Psychotherapy

Various (Rockland, Winston) · 1950

Reviewed population: Patients with borderline personality disorder receiving the structured dynamic supportive treatment evaluated by Clarkin et al. (2007), with medication when indicated.

In a 90-person randomized comparison of TFP, DBT and dynamic supportive treatment over one year, supportive treatment was associated with improvement in depression, anxiety, functioning, social adjustment, anger and facets of impulsivity. The abstract does not establish superiority to untreated or usual-care controls, nor a specific reduction in suicidality for supportive treatment. This assessment concerns the structured dynamic protocol, not every form of supportive counseling.

Dialectical Behavior Therapy for Adolescents

Alec Miller, Jill Rathus, Marsha Linehan · 2007

Reviewed population: Adolescents with borderline personality disorder receiving DBT-A in Schmeck et al. (2023; online 2022).

A nonrandomized comparison included 37 DBT-A and 23 adolescent identity treatment patients. Both received 25 weekly individual sessions plus family sessions and improved in psychosocial and personality functioning, BPD criteria and depression. Baseline age and self-injury differed. These findings provide limited direct BPD evidence; the design cannot establish randomized comparative efficacy or transfer the separate adolescent self-harm guideline to all adolescent PD presentations.

Psychiatric symptoms and functioning improved in both groups; the STIP-TA programme showed larger symptom improvements through follow-up. Assignment was not randomized, so residual confounding remains. Findings concern this inpatient treatment package, not isolated transactional-analysis techniques or every PD subtype.

Why are these approaches listed with Personality Disorders?

The catalogue associates 24 approaches and 0 frameworks with this topic. These links support learning and comparison; association alone is not a treatment recommendation or evidence of effectiveness.

How should I read the evidence assessments?

Assessments are specific to the population and scope stated on each card. They include a rationale, source links, and a review date. An overall review of an approach does not automatically apply to this condition, and a randomized-study label does not by itself mean that a study found benefit.

What does "Assessment not yet completed" mean?

A condition-specific assessment has not been recorded. Approaches with checked sources appear in a separate assessment-pending group; a checked source can support, oppose, or discuss an intervention without recommending it. Neither pending group means that no research exists or that the approach is ineffective. Frameworks are shown separately.
