Dialectical behavioral therapy (DBT) is a form of cognitive behavioral therapy that was developed for suicidal and self-harming people with borderline personality disorder. Later, the intervention has also been adapted for other types of problems such as addiction, eating disorders, depression and post-traumatic stress.
|BPD = Borderline personality disorder; DBT = Dialectical behaviour therapy; MBT = Mentalization based therapy; RCT = Randomized controlled trial; SMD = Standardized mean difference; TAU = Treatment as usual|
|Storebø et al. 2020. |
|Study design: Included only randomised controlled trials.
Included studies: The review included 75 studies, where of 24 investigated the effect of DBT.
|Population: Persons of all ages with a diagnosis of BPD. At least 70% of sample had to have a formal diagnosis.
Control: Outcomes listed are versus a treatment as usual control group. Full review also includes other analysis with active psychotherapeutic controls.
Intervention: Any psychological intervention designed for BPD treatment (including DBT).
SMD: –0.28 (–0.48 to –0.07).
n = 376, 7 RCT.
SMD: –0.23 (–0.68 to 0.23).
n = 231, 5 RCTs.
Other included outcomes: BPD symptom severity, Psychosocial functioning, Anger, Affective instability, Chronic feelings of emptiness, Impulsivity, Interpersonal problems, Dissociation and psychotic-like symptoms, Depression, Attrition, Adverse effects
|Authors conclusion: We found no unequivocal, high-quality evidence to support one BPD-specific therapy over another in the treatment of BPD; our subgroup analyses showed no differences in effect estimates between the different types of therapies. However, compared to TAU, we observed significant effects in favour of DBT for the primary outcomes of BPD severity, self-harm, and psychosocial functioning, and in favour of MBT for self-harm, suicidality, and depression. We rated the quality of the evidence for these outcomes as low, meaning that the true magnitude of these effects is uncertain|

|Witt et al. 2021. |
|Study design: Only included randomised controlled trials.
Included studies: The review included 17 studies, whereof 4 investigated the effect of DBT
|Population: Children and adolescent (<18 years) with a recent (< 6 months) presentation to hospital or clinical services for self-harm (SH). 49.1% of the included participants were diagnosed with borderline personality disorder.
All relevant studies included had a requirement of a history of multiple episodes of SH.
1. Individual CBT-based psychotherapy;
2. Dialectical behavioural therapy;
3. Mentalisation therapy;
4. Group-based psychotherapy;
5. Enhanced assessment approaches;
6. Compliance enhancement approaches;
7. Family interventions;
8. Remote contact interventions.

|Author’s conclusion: “On the basis of data from four trials, DBT for adolescents (DBT-A) reduces repetition of SH at post-intervention compared with TAU, EUC, and alternative psychotherapy.”
“...We also found some positive effects of DBT-A, but methodological factors limit confidence in the generalizability of the results. We recommend further evaluation of these approaches to assess the impact of these interventions in different samples and settings”
|BPD = Borderline personality disorder; CTBE = Community treatment by experts; CVT = comprehensive validation therapy; DBT = Dialectical behaviour therapy; RCT = Randomized controlled trial; SMD = Standardized mean difference; TAU = Treatment as usual|
|Lee et al. 2015. |
|Study design: Only randomised controlled trails.
Included studies: The review included 10 studies, whereof 4 investigated the effect of DBT.
|Population: Patients with BPD (<70% of sample) and a co-occurring substance abuse.
Control: All control groups where included. The included studies used: TAU, CVT and CTBE
Intervention: Multiple psychological treatments, including DBT.
|Suicide or self-harm: No studies indicated that DBT reduced suicide or self-harm
Substance use: Three of four studies indicated that DBT reduced substance use.
|Authors conclusion: “DBT showed generally good outcomes compared with TAU and other non-validated manualised comparison treatments. The studies were of generally good quality. Some studies were confounded by the introduction of pharmacotherapy, which is known to be an effective intervention. The results, although limited by a small number of studies with small sample sizes, suggest that DBT has a good enough evidence base to be utilised with clients with co-occurring BPD and SUD.”|
|QALY = Quality adjusted life years; BPD = Borderline personality disorder; CCT = Client centred therapy; DBT = Dialectical behavioural therapy; TAU = Treatment as usual; CEAC = Cost effectiveness acceptability curve; WTP = Willingness to pay; RCT = Randomised controlled trial|
|Brazier et al. 2006. (4)|
|Systematic review: The literature search resulted in only one relevant cost-effectiveness study.
Analysis: The authors performed own analysis to try to estimate cost-effectiveness from data taken from four clinical studies.
Method: When possible a cost-utility analysis with QALY as outcome was used. If not a cost-effectiveness analysis with avoided parasuicidal events were performed
Perspective: A government perspective excluding voluntary services, unstaffed community accommodation and productivity cost.
Time horizon: 12 months
Costs: United Kingdom, 2003
|Population: Patients with BPD. According to the authors most of the participants where female with co-occurring substance abuse.
Control: Control was either treatment as usual (TAU) or client centred therapy (CCT).
Intervention: The review included multiple psychological therapies, including DBT.

|Authors' conclusion: “In terms of cost-effectiveness, this review attempted to examine the cost-effectiveness of the intervention in six RCTs. The mix of results between the four trials of DBT, along with the high levels of uncertainty and the limitations of the analyses, do not support the cost-effectiveness of DBT, although they suggest that it has the potential to be cost-effective.”|

Total mean annua societal cost‐of‐illness was EUR 28026 during pre‐treatment, EUR 18758 during the DBT treatment year and EUR 14750 during the follow‐up year.
|Authors' conclusion: “The review identified four studies that evaluated the health economic impact of DBT on patients with EUPD. None of these studies provided convincing evidence to support a hypothesis that A/MBIs are a cost‐effective treatment, due in part to economic evaluation design and uncertainty around results.”|

SBU Enquiry Service Consists of structured literature searches to highlight studies that can address questions received by the SBU Enquiry Service from Swedish healthcare or social service providers. We assess the risk of bias in systematic reviews and when needed also quality and transferability of results in health economic studies. Relevant references are compiled by an SBU staff member, in consultation with an external expert when needed.
