Outcome Trajectories and Prognostic Factors for Suicide and Self-Harm Behaviors in Patients With Borderline Personality Disorder Following One Year of Outpatient Psychotherapy

The role of emotion dysregulation and interpersonal dysfunction in nonsuicidal self-injury during dialectical behavior therapy for borderline personality disorder

Dialectical Behaviour Therapy (DBT) is an evidence-based treatment for borderline personality disorder (BPD), with findings demonstrating improvements in various BPD features and related behaviours, such as nonsuicidal self-injury (NSSI). Theory and research suggest that reductions in emotion dysregulation and interpersonal dysfunction could account for at least some of the reduction in NSSI observed during the course of DBT. The current research investigated: 1) the trajectory of changes in emotion dysregulation, interpersonal dysfunction, and NSSI over the course of DBT, and 2) whether changes in emotion dysregulation mediate the relationship between changes in interpersonal dysfunction and changes in NSSI over treatment. One hundred and twenty individuals with BPD enrolled in a multi-site randomized-clinical trial were assessed at five timepoints over 12 months of standard DBT. Results indicated that interpersonal dysfunction and NSSI decreased over the course of DBT. Emotion dysregulation decreased in a quadratic manner such that most of the gains in emotion dysregulation occurred in earlier phases of DBT. Although changes in interpersonal dysfunction predicted changes in emotion dysregulation, changes in emotion dysregulation did not mediate the relationship between changes in interpersonal dysfunction and changes in NSSI.

Pretreatment cognitive performance is associated with differential self-harm outcomes in 6 v. 12-months of dialectical behavior therapy for borderline personality disorder

BACKGROUND

Recent findings suggest that brief dialectical behavior therapy (DBT) for borderline personality disorder is effective for reducing self-harm, but it remains unknown which patients are likely to improve in brief v. 12 months of DBT. Research is needed to identify patient characteristics that moderate outcomes. Here, we characterized changes in cognition across brief DBT (DBT-6) v. a standard 12-month course (DBT-12) and examined whether cognition predicted self-harm outcomes in each arm.

METHODS

In this secondary analysis of 240 participants in the FASTER study (NCT02387736), cognitive measures were administered at pre-treatment, after 6 months, and at 12 months. Self-harm was assessed from pre-treatment to 2-year follow-up. Multilevel models characterized changes in cognition across treatment. Generalized estimating equations examined whether pre-treatment cognitive performance predicted self-harm outcomes in each arm.

RESULTS

Cognitive performance improved in both arms after 6 months of treatment, with no between-arm differences at 12-months. Pre-treatment inhibitory control was associated with different self-harm outcomes in DBT-6 v. DBT-12. For participants with average inhibitory control, self-harm outcomes were significantly better when assigned to DBT-12, relative to DBT-6, at 9-18 months after initiating treatment. In contrast, participants with poor inhibitory control showed better self-harm outcomes when assigned to brief DBT-6 v. DBT-12, at 12-24 months after initiating treatment.

CONCLUSIONS

This work represents an initial step toward an improved understanding of patient profiles that are best suited to briefer v. standard 12 months of DBT, but observed effects should be replicated in a waitlist-controlled study to confirm that they were treatment-specific.

Trajectories and Predictors of Change in Emotion Dysregulation and Deliberate Self-Harm Amongst Adolescents with Borderline Features

BACKGROUND

Deliberate self-harm (DSH) and emotion dysregulation (ED) peaks in adolescence, and is associated with an increased risk of psychopathology, suicide and lower functioning in adulthood. DBT-A has been established as an effective treatment for reducing DSH, however less is known about changes in emotion dysregulation. This study aimed to identify baseline predictors of treatment response in outcome trajectories of DSH and emotion dysregulation.

METHODS

Response trajectories of DSH and ED were investigated using Latent Class Analysis on RCT data comparing DBT-A and EUC for 77 adolescents treated for deliberate self-harm and borderline traits. Logistic regression analysis was used to examine baseline predictors.

RESULTS

Two-class solutions were selected for both indicators, distinguishing between early and late responders in DSH, and responders and non-responders in ED. Higher levels of depression, shorter DSH histories and not receiving DBT-A predicted less favourable response in DSH, while DBT-A was the only predictor of treatment response in ED.

CONCLUSIONS

DBT-A was associated with a significantly faster reduction of deliberate self-harm in the short-term and improved emotion regulation in the long-term.

Corrective Experiences to Enhance Trust: Clinical Wisdom From Good (Enough) Psychiatric Management

Unstable trust within social interchange underlies the symptom constellation of borderline personality disorder (BPD), resulting in preoccupation with intense dyadic relationships, limited capacity for social collaboration, and constricted social networks. Good Psychiatric Management (GPM) provides a distilled formulation of how interpersonal hypersensitivities drive the engine of BPD's symptomatic oscillations in both affect and attachment. The authors summarize clinically relevant conclusions from the empirical literature on trust in BPD, synthesize it with selected ideas from other empirically supported interventions, and distill a formulation of how the GPM approach can address problems of trust in BPD with strategies most clinicians can use to improve their work with patients. GPM's clinical management approach utilizes common factors in psychotherapy to structure collaboration with patients to be accountable partners in treatment, rely on themselves more to diminish unrealistic demands on others, and function more effectively in arenas that expand and stabilize their social network.

A systematic review and meta-analysis of digital interventions targeted at individuals with borderline personality disorder (BPD), emotionally unstable personality disorder (EUPD), and related symptoms

OBJECTIVES

The present review investigates the impact of digital interventions for individuals with features of borderline personality disorder (BPD)/emotional unstable personality disorder (EUPD) as digital interventions show promise as therapeutic tools in underserved groups. BPD/EUPD features are identified as clinically relevant, yet previous reviews on the use of digital interventions fail to include subthreshold symptomatology.

METHODS

Five online databases were searched for terminology in three categories: BPD/EUPD and related symptoms, mental-health interventions, and digital technology. Additionally, four relevant journals and two trial registers were searched for additional papers meeting the inclusion criteria.

RESULTS

Twelve articles met all inclusion criteria. Meta-analyses revealed statistically significant differences in symptom measures between intervention and control groups at postintervention and decreases in BPD/EUPD symptomatology and well-being from pre- to postintervention. Service users' engagement, satisfaction, and acceptability of interventions were high. Results support the previous literature on the value of using digital interventions in populations with BPD/EUPD.

CONCLUSION

Overall, it was identified that digital interventions show promise for successful implementation with this population.

Trajectories and Processes of Symptom Change Over Time in Dialectical Behavior Therapy for Borderline Personality Disorder

Despite ample evidence for Dialectical Behavior Therapy (DBT) as an effective treatment for borderline personality disorder (BPD), close examination of the trajectory of change in BPD symptoms over the course of DBT is lacking. There also remain questions regarding the directionality of changes in different domains of BPD symptoms, such as improvements in dysfunctional behaviors and thoughts/feelings. In order to provide more fine-grained information about the treatment process in DBT, the current study aimed to (a) examine the trajectories of change of BPD-associated negative thoughts/feelings and behaviors, and positive behaviors, and (b) test the temporal relationship between changes in negative behaviors and thoughts/feelings. The study involved 55 adult clients attending a 6-month outpatient DBT program for BPD who completed assessments of BPD symptoms every four sessions. Growth curve models suggested that clients experienced a faster rate of decrease in negative behaviors during the initial phase of treatment, whereas steady rates of improvement were found for negative thoughts/feelings and positive behaviors, respectively, throughout treatment. Further, a random-intercept cross-lagged panel model found that the within-person fluctuations in negative behaviors preceded the within-person changes in negative thoughts/feelings at a subsequent time point during the later phase of treatment, whereas within-person fluctuations in thoughts/feelings were followed by changes in negative behaviors at the beginning and end of the treatment. These results highlighted the complexity of patterns and processes of change in BPD symptomatology during the course of DBT.

Psychosocial interventions for self-harm in adults

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury regardless of degree of suicidal intent or other types of motivation) is a growing problem in most counties, often repeated, and associated with suicide. There has been a substantial increase in both the number of trials and therapeutic approaches of psychosocial interventions for SH in adults. This review therefore updates a previous Cochrane Review (last published in 2016) on the role of psychosocial interventions in the treatment of SH in adults.

OBJECTIVES

To assess the effects of psychosocial interventions for self-harm (SH) compared to comparison types of care (e.g. treatment-as-usual, routine psychiatric care, enhanced usual care, active comparator) for adults (aged 18 years or older) who engage in SH.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Specialised Register, the Cochrane Library (Central Register of Controlled Trials [CENTRAL] and Cochrane Database of Systematic reviews [CDSR]), together with MEDLINE, Ovid Embase, and PsycINFO (to 4 July 2020).

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing interventions of specific psychosocial treatments versus treatment-as-usual (TAU), routine psychiatric care, enhanced usual care (EUC), active comparator, or a combination of these, in the treatment of adults with a recent (within six months of trial entry) episode of SH resulting in presentation to hospital or clinical services. The primary outcome was the occurrence of a repeated episode of SH over a maximum follow-up period of two years. Secondary outcomes included treatment adherence, depression, hopelessness, general functioning, social functioning, suicidal ideation, and suicide.

DATA COLLECTION AND ANALYSIS

We independently selected trials, extracted data, and appraised trial quality. For binary outcomes, we calculated odds ratio (ORs) and their 95% confidence intervals (CIs). For continuous outcomes, we calculated mean differences (MDs) or standardised mean differences (SMDs) and 95% CIs. The overall quality of evidence for the primary outcome (i.e. repetition of SH at post-intervention) was appraised for each intervention using the GRADE approach.

MAIN RESULTS

We included data from 76 trials with a total of 21,414 participants. Participants in these trials were predominately female (61.9%) with a mean age of 31.8 years (standard deviation [SD] 11.7 years). On the basis of data from four trials, individual cognitive behavioural therapy (CBT)-based psychotherapy may reduce repetition of SH as compared to TAU or another comparator by the end of the intervention (OR 0.35, 95% CI 0.12 to 1.02; N = 238; k = 4; GRADE: low certainty evidence), although there was imprecision in the effect estimate. At longer follow-up time points (e.g., 6- and 12-months) there was some evidence that individual CBT-based psychotherapy may reduce SH repetition. Whilst there may be a slightly lower rate of SH repetition for dialectical behaviour therapy (DBT) (66.0%) as compared to TAU or alternative psychotherapy (68.2%), the evidence remains uncertain as to whether DBT reduces absolute repetition of SH by the post-intervention assessment. On the basis of data from a single trial, mentalisation-based therapy (MBT) reduces repetition of SH and frequency of SH by the post-intervention assessment (OR 0.35, 95% CI 0.17 to 0.73; N = 134; k = 1; GRADE: high-certainty evidence). A group-based emotion-regulation psychotherapy may also reduce repetition of SH by the post-intervention assessment based on evidence from two trials by the same author group (OR 0.34, 95% CI 0.13 to 0.88; N = 83; k = 2; moderate-certainty evidence). There is probably little to no effect for different variants of DBT on absolute repetition of SH, including DBT group-based skills training, DBT individual skills training, or an experimental form of DBT in which participants were given significantly longer cognitive exposure to stressful events. The evidence remains uncertain as to whether provision of information and support, based on the Suicide Trends in At-Risk Territories (START) and the SUicide-PREvention Multisite Intervention Study on Suicidal behaviors (SUPRE-MISS) models, have any effect on repetition of SH by the post-intervention assessment. There was no evidence of a difference for psychodynamic psychotherapy, case management, general practitioner (GP) management, remote contact interventions, and other multimodal interventions, or a variety of brief emergency department-based interventions.

AUTHORS' CONCLUSIONS

Overall, there were significant methodological limitations across the trials included in this review. Given the moderate or very low quality of the available evidence, there is only uncertain evidence regarding a number of psychosocial interventions for adults who engage in SH. Psychosocial therapy based on CBT approaches may result in fewer individuals repeating SH at longer follow-up time points, although no such effect was found at the post-intervention assessment and the quality of evidence, according to the GRADE criteria, was low. Given findings in single trials, or trials by the same author group, both MBT and group-based emotion regulation therapy should be further developed and evaluated in adults. DBT may also lead to a reduction in frequency of SH. Other interventions were mostly evaluated in single trials of moderate to very low quality such that the evidence relating to the use of these interventions is inconclusive at present.

Dialectical behavior therapy in the Asia-Pacific Rim region

BACKGROUND

Borderline personality disorder (BPD) contributes to suicide-related morbidity and mortality and requires more intensive psychotherapeutic resources due to its high mental health service usage. Accessibility to an evidence-based treatment program is a cornerstone to support patients with BPD and part of broader suicide prevention efforts as well as improving their quality of life.

AIMS

In this article, the authors aim to discuss and review available dialectical behavior therapy (DBT) and DBT-informed services of selected countries in the Asia-Pacific Rim, namely Singapore, Malaysia, and Mexico.

MATERIALS & METHODS

We contacted providers of different services and gathered information on the process of setting up the service and adapting the treatment, in addition to reviewing the available literature published in the countries.

RESULTS

To date, there have been a pair of DBT-informed services in Singapore, four in Malaysia, and several in Mexico with a few of them offering standard DBT. Different efforts have been put in place to increase the accessibility to training and also the number of DBT practitioners.

DISCUSSION

Important considerations during the process of setting up new services include the use of domestic examples and local language that are contextually appropriate for the local community. Selected challenges faced in common include shortage of workforce, affordability of training programs, and the need for language adaptation with or without translation.

CONCLUSION

Further long-term evaluation of locally adapted DBT-informed mental health services will help to elucidate the effectiveness and efficacy of the program which will potentially serve as a guide for other resource-scarce regions.

Cessation of Deliberate Self-Harm Behavior in Patients With Borderline Personality Traits Treated With Outpatient Dialectical Behavior Therapy

The first aim of the study was to identify when deliberate self-harm (DSH) behavior ceased in patients with borderline symptoms undergoing dialectical behavioral treatment (DBT). The second aim was to compare patients who ceased their self-harm behavior early or late in the course of treatment, with regard to demographics, comorbidity, and symptom severity. The study used a naturalistic design and included 75 treatment completers at an outpatient DBT clinic. Of these 75 patients, 46 presented with self-harming behavior at pre-treatment. These 46 participants where split into two groups, based on median amount of time before ceasing self-harm behavior, termed early (up to 8 weeks) and late (8+ weeks) responders. Treatment duration varied from 16 to 160 weeks. Patients were assessed pre- and post-treatment using measures of depression, hopelessness, personality traits, quality of life, and global assessment of symptoms and functioning. The majority (93.5%) ceased their self-harming within the first year, and the average number of weeks was 15.5 (SD = 17.8). Twenty-five percent of patients ceased their DSH behavior during the first week of treatment. For the remaining patients, the cessation of DSH continued gradually across a 1 year period. We found no differences between early and late responders with respect to demographics, comorbidity, symptom severity, or treatment outcome. None of the patients committed suicide. The findings indicate that self-harming behavior decreases gradually across the first year after starting DBT.

Depression symptoms' impact on personality disorder treatment: Depression symptoms amplifying the interpersonal benefits of negative-affect expression

BACKGROUND

While there is some evidence that patients with elevated depression symptoms experience greater benefits from negative-affect expression, this amplifying effect has not been investigated within a psychotherapeutic context. This is particularly notable considering the substantial evidence linking affect expression with desired outcomes across psychotherapeutic approaches. The primary purpose of the present study was to investigate if depression symptoms amplified (i.e., moderated) the association between negative-affect expression and reductions in interpersonal problems for patients in a psychiatric day treatment for personality disorders. The secondary purpose was to investigate milieu (i.e., other patients concurrently enrolled) negative-affect intensity and its association with patients' reductions in interpersonal problems.

METHODS

Participants (N = 239) were patients consecutively admitted into a psychiatric day treatment program for people with personality disorders. Patients completed measures of (1) depression symptoms at pre-treatment, (2) interpersonal problems at pre- and post-treatment, and (3) negative-affect expression each week of treatment.

RESULTS

The association between patient negative-affect expression and reductions in interpersonal problems was amplified by depression symptoms. Depression symptoms also amplified the association between milieu negative-affect intensity and reductions in interpersonal problems.

CONCLUSIONS

Our findings indicate that depression symptoms amplified the therapeutic value of negative-affect expression and amplified the value of an affectively intense milieu. Practical and theoretical implications are discussed.

Psychological therapies for people with borderline personality disorder

BACKGROUND

Over the decades, a variety of psychological interventions for borderline personality disorder (BPD) have been developed. This review updates and replaces an earlier review (Stoffers-Winterling 2012).

OBJECTIVES

To assess the beneficial and harmful effects of psychological therapies for people with BPD.

SEARCH METHODS

In March 2019, we searched CENTRAL, MEDLINE, Embase, 14 other databases and four trials registers. We contacted researchers working in the field to ask for additional data from published and unpublished trials, and handsearched relevant journals. We did not restrict the search by year of publication, language or type of publication.

SELECTION CRITERIA

Randomised controlled trials comparing different psychotherapeutic interventions with treatment-as-usual (TAU; which included various kinds of psychotherapy), waiting list, no treatment or active treatments in samples of all ages, in any setting, with a formal diagnosis of BPD. The primary outcomes were BPD symptom severity, self-harm, suicide-related outcomes, and psychosocial functioning. There were 11 secondary outcomes, including individual BPD symptoms, as well as attrition and adverse effects.

DATA COLLECTION AND ANALYSIS

At least two review authors independently selected trials, extracted data, assessed risk of bias using Cochrane's 'Risk of bias' tool and assessed the certainty of the evidence using the GRADE approach. We performed data analysis using Review Manager 5 and quantified the statistical reliability of the data using Trial Sequential Analysis.

MAIN RESULTS

We included 75 randomised controlled trials (4507 participants), predominantly involving females with mean ages ranging from 14.8 to 45.7 years. More than 16 different kinds of psychotherapy were included, mostly dialectical behaviour therapy (DBT) and mentalisation-based treatment (MBT). The comparator interventions included treatment-as-usual (TAU), waiting list, and other active treatments. Treatment duration ranged from one to 36 months. Psychotherapy versus TAU Psychotherapy reduced BPD symptom severity, compared to TAU; standardised mean difference (SMD) -0.52, 95% confidence interval (CI) -0.70 to -0.33; 22 trials, 1244 participants; moderate-quality evidence. This corresponds to a mean difference (MD) of -3.6 (95% CI -4.4 to -2.08) on the Zanarini Rating Scale for BPD (range 0 to 36), a clinically relevant reduction in BPD symptom severity (minimal clinical relevant difference (MIREDIF) on this scale is -3.0 points). Psychotherapy may be more effective at reducing self-harm compared to TAU (SMD -0.32, 95% CI -0.49 to -0.14; 13 trials, 616 participants; low-quality evidence), corresponding to a MD of -0.82 (95% CI -1.25 to 0.35) on the Deliberate Self-Harm Inventory Scale (range 0 to 34). The MIREDIF of -1.25 points was not reached. Suicide-related outcomes improved compared to TAU (SMD -0.34, 95% CI -0.57 to -0.11; 13 trials, 666 participants; low-quality evidence), corresponding to a MD of -0.11 (95% CI -0.19 to -0.034) on the Suicidal Attempt Self Injury Interview. The MIREDIF of -0.17 points was not reached. Compared to TAU, psychotherapy may result in an improvement in psychosocial functioning (SMD -0.45, 95% CI -0.68 to -0.22; 22 trials, 1314 participants; low-quality evidence), corresponding to a MD of -2.8 (95% CI -4.25 to -1.38), on the Global Assessment of Functioning Scale (range 0 to 100). The MIREDIF of -4.0 points was not reached. Our additional Trial Sequential Analysis on all primary outcomes reaching significance found that the required information size was reached in all cases. A subgroup analysis comparing the different types of psychotherapy compared to TAU showed no clear evidence of a difference for BPD severity and psychosocial functioning. Psychotherapy may reduce depressive symptoms compared to TAU but the evidence is very uncertain (SMD -0.39, 95% CI -0.61 to -0.17; 22 trials, 1568 participants; very low-quality evidence), corresponding to a MD of -2.45 points on the Hamilton Depression Scale (range 0 to 50). The MIREDIF of -3.0 points was not reached. BPD-specific psychotherapy did not reduce attrition compared with TAU. Adverse effects were unclear due to too few data. Psychotherapy versus waiting list or no treatment Greater improvements in BPD symptom severity (SMD -0.49, 95% CI -0.93 to -0.05; 3 trials, 161 participants), psychosocial functioning (SMD -0.56, 95% CI -1.01 to -0.11; 5 trials, 219 participants), and depression (SMD -1.28, 95% CI -2.21 to -0.34, 6 trials, 239 participants) were observed in participants receiving psychotherapy versus waiting list or no treatment (all low-quality evidence). No evidence of a difference was found for self-harm and suicide-related outcomes. Individual treatment approaches DBT and MBT have the highest numbers of primary trials, with DBT as subject of one-third of all included trials, followed by MBT with seven RCTs. Compared to TAU, DBT was more effective at reducing BPD severity (SMD -0.60, 95% CI -1.05 to -0.14; 3 trials, 149 participants), self-harm (SMD -0.28, 95% CI -0.48 to -0.07; 7 trials, 376 participants) and improving psychosocial functioning (SMD -0.36, 95% CI -0.69 to -0.03; 6 trials, 225 participants). MBT appears to be more effective than TAU at reducing self-harm (RR 0.62, 95% CI 0.49 to 0.80; 3 trials, 252 participants), suicidality (RR 0.10, 95% CI 0.04, 0.30, 3 trials, 218 participants) and depression (SMD -0.58, 95% CI -1.22 to 0.05, 4 trials, 333 participants). All findings are based on low-quality evidence. For secondary outcomes see review text.

AUTHORS' CONCLUSIONS

Our assessments showed beneficial effects on all primary outcomes in favour of BPD-tailored psychotherapy compared with TAU. However, only the outcome of BPD severity reached the MIREDIF-defined cut-off for a clinically meaningful improvement. Subgroup analyses found no evidence of a difference in effect estimates between the different types of therapies (compared to TAU) . The pooled analysis of psychotherapy versus waiting list or no treatment found significant improvement on BPD severity, psychosocial functioning and depression at end of treatment, but these findings were based on low-quality evidence, and the true magnitude of these effects is uncertain. No clear evidence of difference was found for self-harm and suicide-related outcomes. However, compared to TAU, we observed effects in favour of DBT for BPD severity, self-harm and psychosocial functioning and, for MBT, on self-harm and suicidality at end of treatment, but these were all based on low-quality evidence. Therefore, we are unsure whether these effects would alter with the addition of more data.

Machine learning methods for developing precision treatment rules with observational data

Clinical trials have identified a variety of predictor variables for use in precision treatment protocols, ranging from clinical biomarkers and symptom profiles to self-report measures of various sorts. Although such variables are informative collectively, none has proven sufficiently powerful to guide optimal treatment selection individually. This has prompted growing interest in the development of composite precision treatment rules (PTRs) that are constructed by combining information across a range of predictors. But this work has been hampered by the generally small samples in randomized clinical trials and the use of suboptimal analysis methods to analyze the resulting data. In this paper, we propose to address the sample size problem by: working with large observational electronic medical record databases rather than controlled clinical trials to develop preliminary PTRs; validating these preliminary PTRs in subsequent pragmatic trials; and using ensemble machine learning methods rather than individual algorithms to carry out statistical analyses to develop the PTRs. The major challenges in this proposed approach are that treatment are not randomly assigned in observational databases and that these databases often lack measures of key prescriptive predictors and mental disorder treatment outcomes. We proposed a tiered case-cohort design approach that uses innovative methods for measuring and balancing baseline covariates and estimating PTRs to address these challenges.

Refining Suicide Prevention: a Narrative Review on Advances in Psychotherapeutic Tools

PURPOSE OF REVIEW

Since psychotherapies for suicide prevention are receiving increasing attention, our purpose was to evaluate the related literature [meta-analyses and reviews on their effect on suicidal outcomes (A), perspective reviews concerning specific socio-demographic and clinical features (B), original studies with particular interest (C)] published over the last 3 years.

RECENT FINDINGS

(A) Across different diagnoses, particularly, efficacious psychotherapies were cognitive behavioral therapy-based ones and interventions directly addressing suicidal thoughts and behaviors during the treatment. When the focus was restricted to specific diagnoses, results were different: for example, in borderline patients, dialectical behavior therapy and psychodynamic psychotherapies were the only efficacious interventions. (B) Family therapies for adolescents and treatments for elderly depressed patients with disability/cognitive impairment should be further developed. (C) General long-term effects seem to be present, but specific interventions and treatment duration should be considered. Results indicated the presence of a number of promising interventions.
