Anxiety Disorders

Population and scope: Adults with primary generalized anxiety disorder receiving Roemer and Orsillo's acceptance-based behavior therapy (ABBT).

Randomized studies

A 2013 trial randomized 81 adults to 16 sessions of ABBT or applied relaxation. Both groups improved through six-month follow-up, without significant between-treatment differences. This is evidence for the named GAD protocol, not formal equivalence or superiority over applied relaxation, and not evidence for every anxiety diagnosis. The predominantly White research-clinic sample limits generalization.

    US Department of Veterans Affairs / Department of Defense · Version 3.0, April 2024 · Clinical guideline · Recommendation 9; Table 5, p.38

    The 2024 guideline finds insufficient evidence for or against DBT for these outcomes. This recommendation is separate from NICE’s BPD recommendation.

    Scope: Adults aged 18 and over at risk of suicide; DBT for reducing suicidal ideation, suicide attempts or suicide.

    Discussed in the source

    NICE says to consider the adolescent adaptation, DBT-A, for this specified self-harm population. This does not grade every DBT programme or suicide-related outcome.

    Scope: Children and young people with significant emotional dysregulation and frequent self-harm

  • Clinical Practice Guideline for Management of PTSD and Acute Stress Disorder

    VA/DoD · 2023 · Clinical guideline · Recommendation 10; Table 6, p.36

    Insufficient evidence for or against

    VA/DoD finds insufficient evidence for or against DBT for PTSD. This assessment does not determine its status for other conditions.

    Scope: Individual psychotherapy for adults with PTSD.

    Insufficient evidence for or against

    APA finds insufficient evidence to recommend one of these treatment arrangements over the other. This does not assess DBT for BPD.

    Discussed in the source

    DBT is named in the reviewed third-wave therapy category. WHO recommends that category alongside other structured therapies; it does not give DBT a separate recommendation or separate certainty rating here.

    Scope: Adults with moderate-to-severe depression, within the mhGAP non-specialist-care context.

    Discussed in the source

    WHO conditionally supports digital interventions based on approaches including DBT, with low-certainty evidence. This is not a recommendation for every full DBT program, and the reviewed trials did not establish benefit for attempts or deaths and were underpowered for those outcomes.

    Scope: Digital support for people with suicidal thoughts.

Condition-specific assessments

Each conclusion applies to the population and use described. These source-based assessments do not certify the full entry or replace expert clinical review.

Personality Disorders

Population and scope: 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.

Guideline recommendation

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.

Suicidality & Self-Harm

Population and scope: Adults at suicide risk across diagnoses in the VA/DoD review; separate positive guidance applies to women with BPD and recurrent self-harm.

Guideline evidence inconclusive

VA/DoD 2024 recommendation 9 found insufficient evidence for or against DBT for suicidal ideation, attempts or suicide death in its broader adult population. This does not refute the narrower NICE CG78 1.3.4.5 recommendation to consider comprehensive DBT for women with BPD when reducing recurrent self-harm is a priority, assessed separately under personality disorders. DBT-A and digital DBT-based support have different recommendations. Combined self-harm outcomes are not equivalent to suicide attempts or deaths. VA/DoD’s evidence search ended on 15 March 2023; later studies were not reviewed in this assessment.

Eating Disorders

Population and scope: Adults meeting DSM-IV binge-eating disorder research criteria, receiving the DBT-BED group adaptation.

Randomized studies

A 101-participant RCT compared 20 DBT-BED group sessions with active group therapy. DBT-BED produced faster binge reduction and less dropout, but between-group abstinence advantages did not persist during follow-up. This is evidence for the BED adaptation, not for generic DBT across anorexia, bulimia and all eating disorders.

How they work

Acceptance-Based Behavior Therapy

Core mechanism: Reducing experiential avoidance of anxious internal states through mindful awareness and acceptance, combined with clarifying values and taking committed action, breaks the cycle of worry and behavioral restriction that maintains GAD

Ontology: Anxiety disorders, particularly GAD, are maintained by the struggle against internal experience. The problem is not anxiety itself but the avoidance of anxiety that narrows behavioral repertoire and prevents valued living.

DBT

Core mechanism: Skills training (mindfulness, distress tolerance, emotion regulation, interpersonal effectiveness) + behavioral contingency management + dialectical validation reduces dysregulation

Ontology: Biosocial model: biological emotional vulnerability + invalidating environment → pervasive emotion dysregulation

What each assumes — and misses

Acceptance-Based Behavior Therapy

Philosophical roots: Hayes (acceptance and commitment; contextual behavioral science); Kabat-Zinn (mindfulness-based stress reduction); Borkovec (GAD as cognitive avoidance); behavioral learning theory; Buddhist psychology (non-judgmental awareness)

Blind spots: Substantial overlap with ACT makes independent identity difficult to maintain in the field; limited dissemination infrastructure compared to ACT; primarily validated for GAD rather than broad transdiagnostic application

Therapeutic voice: What would you do this week if anxiety weren't running the show? Not if it were gone. If it were still there and just wasn't the one deciding.

DBT

Philosophical roots: Zen Buddhism (mindfulness, radical acceptance); Hegel (dialectical synthesis of opposites); behaviorism (Skinner); biosocial model has no single philosophical ancestor

Blind spots: Heavy skill emphasis can feel prescriptive; may not address underlying trauma directly; requires significant client commitment

Therapeutic voice: It makes complete sense that you want to call him, and calling him tonight will cost you tomorrow. Both of those are true at once. What does wise mind say?

Choosing between them

Acceptance-Based Behavior Therapy and DBT both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
