RESUMO
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.

OBJECTIVE: We investigated whether defense mechanisms in patients with borderline personality disorder (BPD) predict treatment response of dialectical behavior therapy (DBT) and whether they moderate outcome in different treatment lengths. METHOD: We analyzed a subsample of 60 outpatients with BPD, randomized into either 6 (n = 30) or 12 (n = 30) months of DBT. The average level of defensive adaptiveness, assessed with observer-rated overall defensive functioning (ODF) and "immature" (i.e., maladaptive) defenses were used as predictors and moderators of self-reported frequency of self-harm. We conducted a Generalized Linear Mixed Model (GLMM). RESULTS: A lower ODF at treatment onset predicted smaller reductions in self-harm, irrespective of treatment length (IRR = 0.92, 95% CI = [0.86, 0.99], p = .020). Lower order "immature" ("major image distorting") defenses showed significantly smaller (IRR = 1.13, 95% CI = [1.06, 1.21], p < .001) and higher order "immature" ("minor image distorting") defenses showed significantly larger (IRR = .91, 95% CI = [.85, .97], p = .006) reductions in self harm in the 6-month but not in the 12-month treatment. CONCLUSION: Even though the results have to be regarded as preliminary due to the small sample size, findings might indicate that patients with BPD and lower average defensive adaptiveness may benefit from individualized treatment plans including specific interventions targeting defense function.
RESUMO
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.

Despite nearly 30 years of research demonstrating its effectiveness in the treatment of borderline personality disorder (BPD) and related problems, few studies have investigated mechanisms of change for dialectical behavior therapy (DBT; Linehan, 1993a). Improvements in mindfulness and emotion regulation have been highlighted as key potential mechanisms of change in DBT (Lynch et al., 2006). The present study examined the time course of and associations between mindfulness, emotion regulation, and BPD symptoms during DBT. Participants were 240 repeatedly and recently self-harming adults (Mage = 27.75) with BPD who were randomly assigned to receive either 6 or 12 months of standard DBT. Primary hypotheses were that: (a) changes in mindfulness would occur before changes in emotion regulation, and (b) changes in emotion regulation would mediate the association of changes in mindfulness with changes in BPD symptoms. Results from changepoint analysis illuminated the proportion of participants for whom first changes occurred in emotion regulation (40.7%), mindfulness (32.4%), or both (26.9%). Contrary to hypotheses, five-wave, cross-lagged analyses did not indicate mediational effects of either mindfulness or emotion regulation on the association of either variable with change in BPD symptoms. Supplemental analyses, however, suggested that changes in emotion regulation mediated the inverse association of changes in mindfulness with changes in BPD symptoms. Findings highlight patterns of change in key, proposed mechanisms of change in DBT and suggest important future research directions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Borderline personality disorder (BPD) is characterized by instability in interpersonal, affective, cognitive, self-identity, and behavioral domains. For a BPD diagnosis, individuals must present at least five of nine symptoms, resulting in 256 possible symptom combinations; thus, individuals diagnosed with BPD can differ substantially. Specific symptoms of BPD tend to co-occur, suggesting BPD subgroups. To explore this potential, we analyzed data from 504 participants diagnosed with BPD enrolled in one of three randomized controlled trials conducted at center for Addiction and Mental Health in Toronto, Canada from 2002 to 2018. An exploratory latent class analysis (LCA) was conducted to identify symptom subgroups of BPD. Analyses indicated three latent subgroups. The first group (n = 53) is distinguished by a lack of affective instability and low levels of dissociative symptoms (non-labile type). The second group (n = 279) is characterized by high levels of dissociative and paranoid symptoms but low abandonment fears and identity disturbance (dissociative/paranoid type). The third group (n = 172) is characterized by high efforts to avoid abandonment and interpersonal aggression (interpersonally unstable type). Homogenous symptom subgroups of BPD symptoms exist and may have important implications for how to refine BPD treatment interventions.

PURPOSE OF REVIEW: Individuals with personality disorders are frequently seen in mental health settings. Their symptoms typically reflect a high level of suffering and burden of disease, with potentially harmful societal consequences, including costs related to absenteeism at work, high use of health services, ineffective or harmful parenting, substance use, suicidal and non-suicidal self-harming behavior, and aggressiveness with legal consequences. Psychotherapy is currently the first-line treatment for patients with personality disorders, but the study of psychotherapy in the domain of personality disorders faces specific challenges. RECENT FINDINGS: Challenges include knowing what works for whom, identifying which putative mechanisms of change explain therapeutic effects, and including the social interaction context of patients with a personality disorder. By following a dimensional approach, psychotherapy research on personality disorders may serve as a model for the development and study of innovative psychotherapeutic interventions. We recommend developing the following: (a) an evidence base to make treatment decisions based on individual features; (b) a data-driven approach to predictors, moderators, and mechanisms of change in psychotherapy; (c) methods for studying the interaction between social context and psychotherapy.

INTRODUCTION: Evidence-based psychotherapies for borderline personality disorder (BPD) are lengthy, posing a barrier to their access. Brief psychotherapy may achieve comparable outcomes to long-term psychotherapy for BPD. Evidence is needed regarding the comparative effectiveness of short- versus long-term psychotherapy for BPD. OBJECTIVE: The aim was to determine if 6 months of Dialectical Behavior Therapy (DBT) is noninferior to 12 months of DBT in terms of clinical effectiveness. METHODS: This two-arm, single-blinded, randomized controlled noninferiority trial with suicidal or self-harming patients with BPD was conducted at two sites in Canada. Participants (N = 240, M (SD)age = 28.27 (8.62), 79% females) were randomized to receive either 6 (DBT-6) or 12 months (DBT-12) of comprehensive DBT. Masked assessors obtained measures of clinical effectiveness at baseline and every 3 months, ending at month 24. DBT-6 and DBT-12 were outpatient treatments consisting of weekly individual therapy sessions, weekly DBT skills training group sessions, telephone consultation as needed, and weekly therapist consultation team meetings. RESULTS: The noninferiority hypothesis was supported for the primary outcome, total self-harm (6 months: margin = -1.94, Mdiff [95% CI] = 0.16 [-0.14, 0.46]; 12 months: margin = -1.47, Mdiff [95% CI] = 0.04 [-0.17, 0.23]; 24 months: margin = -1.25, Mdiff [95% CI] = 0.12 [-0.02, 0.36]). Results also supported noninferiority of DBT-6 for general psychopathology and coping skills at 24 months. Furthermore, DBT-6 participants showed more rapid reductions in BPD symptoms and general psychopathology. There were no between-group differences in dropout rates. CONCLUSIONS: The noninferiority of a briefer yet comprehensive treatment for BPD has potential to reduce barriers to treatment access.

Methods for studying therapeutic alliance have primarily examined the impact of the early alliance on outcomes. This does not allow for an understanding of the contributions of client, therapist, and dyadic factors to the alliance. Also, the alliance may change over time, highlighting the need for longitudinal methods. Efforts have been made to develop approaches that decompose the contributing factors and their impact on outcomes, but these findings may not apply to clients with borderline personality disorder (BPD). Our study extends previous research by replicating Baldwin et al.'s (2007) approach to disentangling therapist versus client-therapist dyad effects while using a time-varying framework. Participants (n = 156) were individuals diagnosed with BPD randomized to 1 year of dialectical behavior therapy or general psychiatric management. Outcomes were general psychiatric severity and interpersonal functioning measured at baseline and every 4 months. Client-rated alliance was measured at these time points. Early alliance predicted interpersonal functioning (p = .0132) with a significant contribution from clients (p = .0248) but not therapists (p = .2854). In the time-varying analysis, client contribution to the alliance was significant (p = .0022). For general psychiatric severity, client contributions to the alliance were significant (p < .0001) but not therapist contributions (p = .6779). Client contribution to the alliance was significant (p = .0168) in the time-varying model. Results suggest that in a BPD sample, time-varying alliance is a better predictor of rate of change in outcomes compared with the alliance measured at a single time point. In contrast to other studies, client, not therapist, contributions to alliance were significant in predicting outcomes. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The literature on the application of repetitive transcranial magnetic stimulation (rTMS) in Borderline Personality Disorder (BPD) is unclear, even though its neuromodulatory effects on underlying neural circuitry involved in BPD symptoms suggest that it could be a potential treatment option. We sought to review the evidence on rTMS as a treatment option in BPD. PubMed (for Medline database), Google Scholar, and Scopus were systematically searched following the PRISMA guidelines for studies of any design examining the application of the rTMS treatment in adult patients with precise and primary diagnosis of BPD written in the English language. The systematic review has been registered on PROSPERO (CRD42020215927). Forty one records were screened, and eight fulfilled inclusion criteria (total of 63 patients). The existing studies suggest that rTMS is a well-tolerated treatment in patients with BPD. Double-blind randomized controlled studies are necessary to help elucidate the effects of rTMS in the different symptoms in BPD and establish efficacy and the best cortical targets and stimulation protocols. Longitudinal studies that combine evidenced based psychotherapy with rTMS may be a future line of investigation that could potentially improve outcomes for this population.

INTRODUCTION: Caregivers of youth with mental health (MH) challenges are often faced with complex problems in relation to caring for their youth. Family Connections™ (FC) is a 12-week skills training program for families of individuals with MH challenges, developed originally for Borderline Personality Disorder. Research is needed to examine the effectiveness of FC for caregivers of youth with diverse MH challenges. OBJECTIVE: To examine the effectiveness of FC for caregivers of youth with MH challenges. METHODS: A total of 94 caregivers of youth with MH challenges participated in FC, across three sites in Ontario, Canada. Assessments occurred at baseline, 6 weeks, 12 weeks and follow-up. Primary outcomes include the Burden Assessment Scale and The Stress Index for Parents of Adolescents. Secondary outcomes included the caregiver's report of child behaviour, affect, mastery, coping and grief. Linear mixed model analyses were conducted, where time and the time × site interaction were defined as the fixed effects. RESULTS: Statistically significant improvements over time were observed across outcome measures, including caregiver burden, grief, coping, and other measures. The time × site interaction was only significant for burden (P = .005). CONCLUSION: This study demonstrates the effectiveness of FC for caregivers of youth with MH challenges. Future research should focus on differences across geographical sites and facilitation models. PATIENT OR PUBLIC CONTRIBUTION: Caregivers were involved in the facilitation of FC. A person with lived experience was involved in analysing the data, reporting the results, and drafting the manuscript.

BACKGROUND: The Family Connections™ (FC) program is a 12-week support and skill-training program for caregivers of youth with mental health challenges. The intervention was originally developed with a focus on borderline personality disorder (BPD). It is important to understand the experiences of caregivers in such interventions, as well as its applicability beyond BPD, for the purposes of evaluation and ongoing program improvement. OBJECTIVE: To explore and analyse the experiences of caregivers of youth with diverse mental health challenges and who participated in FC. DESIGN: Semi-structured interviews with thirteen FC-participating caregivers of youth with mental health challenges. RESULTS: Thematic analysis uncovered three major themes regarding caregivers' experience with FC: (a) FC increased the caregivers' ability to manage their youth's mental health challenges; (b) participating in FC impacted their intra- and interpersonal spheres; and (c) improvements to the program were proposed. Following participation in FC, caregivers felt they learned a new approach to understanding themselves, their youth and mental health, and were better able to manage their youth's mental health challenges. DISCUSSION AND CONCLUSION: FC is a promising intervention for caregivers of youth with mental health challenges, beyond the traditional BPD focus. The intervention has the potential to provide broad-based benefits for caregivers and should be considered for implementation and scale-up across youth- and caregiver-serving organizations. Potential areas of intervention flexibility and improvement are discussed. PATIENT/PUBLIC CONTRIBUTION: Caregivers were involved in the program development and facilitation of FC. A person with lived experience was involved with the analysis.

BACKGROUND: No evidence-based therapy for borderline personality disorder (BPD) exhibits a clear superiority. However, BPD is highly heterogeneous, and different patients may specifically benefit from the interventions of a particular treatment. METHODS: From a randomized trial comparing a year of dialectical behavior therapy (DBT) to general psychiatric management (GPM) for BPD, long-term (2-year-post) outcome data and patient baseline variables (n = 156) were used to examine individual and combined patient-level moderators of differential treatment response. A two-step bootstrapped and partially cross-validated moderator identification process was employed for 20 baseline variables. For identified moderators, 10-fold bootstrapped cross-validated models estimated response to each therapy, and long-term outcomes were compared for patients randomized to their model-predicted optimal v. non-optimal treatment. RESULTS: Significant moderators surviving the two-step process included psychiatric symptom severity, BPD impulsivity symptoms (both GPM > DBT), dependent personality traits, childhood emotional abuse, and social adjustment (all DBT > GPM). Patients randomized to their model-predicted optimal treatment had significantly better long-term outcomes (d = 0.36, p = 0.028), especially if the model had a relatively stronger (top 60%) prediction for that patient (d = 0.61, p = 0.004). Among patients with a stronger prediction, this advantage held even when applying a conservative statistical check (d = 0.46, p = 0.043). CONCLUSIONS: Patient characteristics influence the degree to which they respond to two treatments for BPD. Combining information from multiple moderators may help inform providers and patients as to which treatment is the most likely to lead to long-term symptom relief. Further research on personalized medicine in BPD is needed.

Understanding of the biological factors that run in families affected with borderline personality disorder (BPD) is limited. The authors investigated the familial aggregation of neurophysiological biomarkers of response inhibition in the first-degree biological relatives of probands with BPD and associations with psychiatric diagnosis and impulsive traits. In the present study, psychiatric diagnoses and impulsive traits were measured in BPD probands (n = 86), psychiatrically affected and non-affected relatives (n = 60) and controls (n = 83). While undergoing neuroimaging using functional near-infrared spectroscopy, prefrontal cortex (PFC) activation was measured during a go/no-go response inhibition task and compared between probands, relatives and controls. Additionally, non-psychiatrically affected relatives and controls were contrasted to examine the potential impact of familial risk for BPD on response inhibition-related PFC activation in the absence of confounding psychiatric morbidity. Probands showed bilateral decreases in PFC activation during response inhibition compared to relatives and controls. Conversely, both affected and non-affected relatives displayed higher activation than controls and probands in left lateral/medial and right medial PFC, although non-affected relatives showed a lesser extent of activation than affected relatives. Probands and controls reporting greater impulsive traits displayed deactivation across the PFC during response inhibition, whereas relatives showed increased activation. In this first family study of neuroimaging biomarkers in BPD, we show that the familial risk for BPD is reflected in activation of the PFC during response inhibition, with lifetime psychiatric diagnosis and higher impulsive traits in relatives associated with larger increases in PFC activity. Higher PFC activity during response inhibition including among non-affected relatives could reflect a neurophysiological compensatory mechanism.

Emotional and interpersonal instability are core features of borderline personality disorder (BPD) and can pose a challenge for the therapeutic relationship. In dialectical behavior therapy (DBT) for BPD, ruptures in the therapeutic alliance are considered through a behavioral lens that examines the client's relational learning history, the function and context of the rupture, as well as the patterns of emotional processing difficulties that underlie interpersonal conflict. In this article, we use the case of Rachel to illustrate how alliance-focused approach can be integrated with DBT case formulation to enhance treatment planning and the successful negotiation of alliance ruptures.

Personality disorders (PD) carry high psychosocial dysfunction and are associated with treatment resistance in nonspecialized care. Psychodynamic therapies (PDT) are often used to treat PDs, but there has never been a systematic meta-analysis of PDT trials for PD. To evaluate the evidence base for PDTs for PDs across multiple outcome domain, a systematic search for PDT for PD trials was conducted through PubMed and PsycINFO. Sixteen trials were identified, comprising 19 dynamic, 8 active, and 9 control groups predominantly reflecting treatment of borderline and mixed Cluster C PDs, and a random effects meta-analysis was undertaken. PDTs were superior to controls in improving core PD symptoms (g = -0.63; 95% confidence interval [CI; -0.87, -0.41]), suicidality (g = -0.79, p = .02; 95% CI [-1.38, -0.20]), general psychiatric symptoms (g = -0.47; 95% CI [-0.69, -0.25]), and functioning (g = -0.66; 95% CI [-1.01, -0.32]), but not for interpersonal problems due to heterogeneity (g = -1.25; 95% CI [-3.22, 0.71]). Outcomes for PDTs were not different from other active treatments in core PD (g = 0.05; 95% CI [-0.25, 0.35]) or other symptoms. This pattern continued into posttreatment follow-up (average 14 months). Study quality was generally rated as adequate and was unrelated to outcomes. Compared with other treatments, PDTs do not have different acute effects and are superior to controls, although only trials treating BPD employed active controls and non-BPD trials were of lower quality. Underresearched areas include narcissistic PD, specific Cluster C disorders, and personality pathology as a continuous construct. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Treatment dropout among individuals with borderline personality disorder (BPD) is associated with negative psychosocial outcomes. Identifying predictors of dropout among this population is critical to understanding how to improve treatment retention. The present study extends the current literature by examining both static and dynamic predictors of dropout. Chronically suicidal outpatients diagnosed with BPD (N = 42) were randomly assigned to a 20-week dialectical behavior therapy (DBT) skills training group. Static and dynamic predictors were assessed at baseline, 5, 10, 15, 20 weeks, and 3 months post-intervention. A post-hoc two-stage logistic regression analysis was conducted to predict dropout propensity. Receiving disability benefits at baseline and decreases in mindfulness were associated with significantly increased probability of dropout. Clinicians working with chronically self-harming outpatients diagnosed with BPD would benefit from prioritizing clinical interventions that enhance mindfulness in order to decrease dropout propensity.

This study aimed to examine which specific emotion processes influence self-inflicted injury: basal respiratory sinus arrhythmia, baseline negative emotional intensity, emotional reactivity, or emotion regulation deficits. Self-injuring individuals with borderline personality disorder (N = 22) reported their lifetime self-injury frequency. Basal respiratory sinus arrhythmia and baseline skin conductance responses measurements were collected. Participants then either reacted as they usually would (i.e., emotional reactivity), or utilized mindfulness- or distraction-based strategies (i.e., emotion regulation), in response to negative images while self-reported negative emotion and skin conductance were monitored. Higher basal respiratory sinus arrhythmia and baseline emotional intensity predicted higher lifetime self-injury frequency. Chronic, resting emotion processes may be more important targets for reducing self-injury compared to labile, acute emotion processes.

Despite research supporting the effectiveness of dialectical behavior therapy (DBT) for borderline personality disorder (BPD), few studies have examined how DBT leads to clinical change. DBT is theorized to lead to improved clinical outcomes by enhancing the capacity for emotion regulation, including improvement in skills (e.g., mindfulness and distress tolerance) for managing emotional distress and impulsive behaviors. Therefore, the aim of this study was to test whether improvements in mindfulness and distress tolerance indirectly affect the relationship between DBT skills training and clinical outcomes. The sample consists of 84 patients diagnosed with BPD who were enrolled in a randomized controlled trial comparing 20 weeks of DBT-skills group (DBT-S) to an active waitlist control. Mindfulness and distress tolerance were assessed at baseline and at the end of the 20 weeks. BPD symptoms, general psychiatric symptoms, and social adjustment were assessed at the end of 20 weeks and combined into a latent variable representing a broad assessment of general psychopathology. Relative to the waitlist control group, improvements in mindfulness and distress tolerance each independently indirectly affected the relationship between DBT-S and posttreatment general psychopathology. Findings suggest that DBT-S exerts its effects on outcomes through improvements in mindfulness and distress tolerance. These findings support the significance of mindfulness and distress tolerance in DBT-S for BPD. Limitations, future directions, and clinical implications are discussed.

BACKGROUND: Concurrent mental health and substance use disorders among youth are associated with functional impairment in developmentally salient domains, yet research on prevention and intervention for this vulnerable population is sparse. This paper describes the rationale and design of the Research and Action for Teens study, an initiative designed to strengthen the evidence base for prevention, screening, treatment and service delivery for youth concurrent mental health and substance use concerns. METHODS: Four sub-studies were developed: (1) a cohort study examining the emergence of mental health and substance use concerns from early to mid-adolescence; (2) a screening and diagnosis study validating screening tools with a diagnostic interview; (3) a treatment study examining the feasibility and effectiveness of dialectical behaviour therapy skills training interventions for youth and family members; and (4) a systems study implementing cross-sectoral collaborative networks of youth-serving agencies using a common screening tool. RESULTS: Multiple stakeholders, including service providers from youth-serving agencies across sectors, consumer groups and family members participated in an initial consultation, and in the implementation of 4 sub-studies. CONCLUSIONS: Collaboration with community stakeholders across sectors and disciplines throughout the research process is challenging but feasible, and is important for the production of applicable knowledge across the continuum of care.

BACKGROUND: Borderline personality disorder (BPD) is characterized by a heterogeneous clinical phenotype that emerges from interactions among genetic, biological, neurodevelopmental, and psychosocial factors. In the present family study, we evaluated the familial aggregation of key clinical, personality, and neurodevelopmental phenotypes in probands with BPD (n = 103), first-degree biological relatives (n = 74; 43% without a history of psychiatric disorder), and non-psychiatric controls (n = 99). METHODS: Participants were assessed on DSM-IV psychiatric diagnoses, symptom dimensions of emotion dysregulation and impulsivity, 'big five' personality traits, and neurodevelopmental characteristics, as part of a larger family study on neurocognitive, biological, and genetic markers in BPD. RESULTS: The most common psychiatric diagnoses in probands and relatives were major depression, substance use disorders, post-traumatic stress disorder, anxiety disorders, and avoidant personality disorder. There was evidence of familial aggregation for specific dimensions of impulsivity and emotion dysregulation, and the big five traits neuroticism and conscientiousness. Both probands and relatives reported an elevated neurodevelopmental history of attentional and behavioral difficulties. CONCLUSIONS: These results support the validity of negative affectivity- and impulse-spectrum phenotypes associated with BPD and its familial risk. Further research is needed to investigate the aggregation of neurocognitive, neural and genetic factors in families with BPD and their associations with core phenotypes underlying the disorder.
