The borderline interpersonal-affective systems (BIAS) model: Extending understanding of the interpersonal context of borderline personality disorder

A pilot and feasibility study of Sage: A couple therapy for borderline personality disorder

Objective: Borderline personality disorder (BPD) is characterized by emotion dysregulation and relationship dysfunction. However, the majority of BPD treatments provide individually-focused treatment and do not target relationship functioning or include significant others. The current paper presents the primary and secondary outcomes from an uncontrolled trial of Sage, a manualized conjoint treatment for people with BPD and their intimate partners that targets BPD, relationship conflict, and partner mental health simultaneously. Method: Sixteen couples wherein one member has BPD and elevated suicidal ideation/chronic and frequent suicidal/self-injurious behavior were enrolled in the 12-session Sage protocol. Measures of BPD severity (including suicidal ideation, suicidal/self-injurious behaviors, and emotion dysregulation) and relationship outcomes were collected at pre-, mid-, and post-intervention, and three-month follow-up. Results: Self-reported BPD severity, suicidal ideation, and emotion dysregulation and interview-rated frequency of suicidal and self-injurious behaviors improved from baseline to follow-up. No changes were observed in relationship outcomes or informant-reported BPD severity and suicidal ideation. Conclusions: These findings suggest that Sage may aid in improving BPD pathology with moderate to large effect sizes. The lack of improvements in relationship outcomes may be due to the relatively high relationship functioning observed in couples at baseline, but more testing is needed.Trial registration: ClinicalTrials.gov identifier: NCT04737252..

Individual patterns and synchrony of heart rate variability in adolescent patients with borderline personality psychopathology and their mothers: a case-control study

BACKGROUND

In adolescent Borderline Personality Disorder (BPD), interactions with caregivers often provoke dysregulation. Vagally-mediated heart rate variability (HRV), a physiological marker of regulatory capacities, shows alterations in BPD. Studies on individual and dyadic HRV in adolescents with BPD (BPD-A) and their mothers (BPD-M) are lacking. We examined 1) individual resting state -, reactivity- and recovery- HRV, 2) intrapersonal concordance of interactional quality with HRV, 3) mother-adolescent interpersonal HRV-synchrony and 4) the association of interpersonal HRV-synchrony with behavioral synchrony in a case-control design.

METHODS

Thirty-eight (sub)syndromal BPD-A and BPD-M were compared to 35 healthy control adolescents and their mothers (HC-A/-M). HRV was assessed during a positive interaction, a stress task and resting before and after interactions (recovery). Behavior during interactions was observed and coded using the "Coding Interactive Behavior"- Manual. Data were analyzed using multilevel modeling.

RESULTS

BPD-A showed a lower resting HRV than HC-A, while no group differences were found for mothers. From resting to positive interaction, BPD-A/BPD-M/HC-M showed a significant increase in HRV; this increase was not significant for HC-A. HRV-reactivity to stress was not significant in either group but influenced by general emotional and behavioral problems within both adolescent samples. Significant intrapersonal concordance of HRV and behavior could only be found for HC-M during the positive interaction (positive association). For BPD-M, a complete disconnect between behavior and HRV was observed. BPD-dyads and dyads lower in behavioral synchrony displayed HRV-synchrony during stress, in HC-dyads and dyads higher in behavioral synchrony during rest after dyadic interactions.

CONCLUSIONS

Our study is the first investigating altered HRV-reactivity, behavior-HRV-concordance and HRV-synchrony in adolescents with BPD traits and their mothers, adding new insight to physiological regulation and co-regulation in adolescent BPD pathology. Limitations and implications of these results are discussed.

A Longitudinal Prediction of Suicide Attempts in Borderline Personality Disorder: A Machine Learning Study

Borderline personality disorder (BPD) is associated with a high risk of suicide. Despite several risk factors being known, identifying vulnerable patients in clinical practice remains a challenge so far. The current study aimed at predicting suicide attempts among BPD patients during disorder-specific psychotherapeutic interventions exploiting machine learning techniques. The study took into account several potential predictors relevant to BPD psychopathology: emotion dysregulation, temperamental and character factors, attachment style, impulsivity, and aggression. The sample included 69 patients with BPD who completed the Temperament and Character Inventory, Attachment Style Questionnaire, Difficulties in Emotion Regulation Scale, Barratt Impulsiveness Scale, and Aggression Questionnaire at baseline and after 6 months of psychotherapy. To detect future suicide attempts, baseline questionnaires were entered as predictors into an elastic net penalized regression, whose predictive performance was assessed through nested fivefold cross-validation. At the same time, 5000 iterations of a non-parametric bootstrap were used to determine predictors' robustness. The elastic net model discriminating BPD suicide attempters from non-attempters reached a balanced accuracy of 64.09% and an area under the receiver operating curve of 70.44%. High preoccupation with relationships, harm avoidance, and reward dependence, along with low motor impulsiveness, verbal aggression, cooperativeness, and self-transcendence were the most contributing predictors. Our findings suggest that interpersonal vulnerability and internalizing factors are the strongest predictors of future suicide attempts in BPD. Machine learning on self-report psychological scales may be helpful to identify individuals at suicidal risk, potentially helping clinical settings to develop individualized preventive strategies.

Communication Between Individuals With Borderline Personality Disorder and Their Partners

Borderline personality disorder (BPD) is characterized by frequent and intense conflict in intimate relationships. Emerging theoretical perspectives have suggested that communication from both individuals with BPD and their partners during times of conflict may exacerbate BPD pathology and therefore reflect an important target for intervention. Communication samples between individuals with BPD and their partners (N = 18 couples) who were seeking conjoint therapy were coded using the Rapid Marital Interactions Coding System-2. No differences were found in the amount of positive, constructive or hostile communication between individuals with BPD and their partners, and both partners used significantly more constructive communication than positive or hostile, though they were misaligned in their use of constructive communication. These findings challenge the notion that individuals with BPD communicate in a more hostile or conflictual way than their partners, despite the stigma they face in healthcare and community settings.

Antecedents and risk factors for borderline personality disorder: Etiopathogenic models based on a multi-level meta-analysis

BACKGROUND

Empirically-based developmental psychopathology approach identified three domains involved in the emergence of borderline personality disorder (BPD): i) underlying liabilities to develop psychopathology (i.e., early patterns of internalizing and externalizing manifestations); ii) invalidating relational experiences (e.g., childhood traumatic experiences, maladaptive parenting, problematic peer relationships); iii) regulatory mechanisms of emotions and behaviors. Nevertheless, no studies have quantitatively summarized empirical findings concerning how and to what extent these domains might be temporally associated to the emergence of BPD features from adolescence to adulthood.

METHODS

The current multi-level meta-analysis included 106 studies (N = 86,871 participants) assessing the role of previously mentioned antecedents and risk factors for BPD.

RESULTS

The analysis showed moderate effect sizes capturing temporal associations between early internalizing/externalizing psychopathological manifestations, different invalidating relational experiences, emotion/behavior regulation processes with later BPD features. The effect sizes of these domains were not statistically different from each other.

CONCLUSION

This evidence supports a transactional developmental model of BPD. Consistently, the emergence of BPD could be viewed in the light of dynamic interplays between an underlying liability to psychopathology and invalidating relational experiences across different stages of development, which are progressively reinforced through increasing alterations of emotion and behavior regulation mechanisms.

Update on the Neurobiology of Borderline Personality Disorder: A Review of Structural, Resting-State and Task-Based Brain Imaging Studies

PURPOSE OF REVIEW

This review summarizes recent advances in research on the neurobiology of borderline personality disorder (BPD) according to structural brain imaging investigations and resting-state and task-based functional brain activation studies.

RECENT FINDINGS

Extending established findings on differences in regional brain volumes and cortical thickness between BPD and healthy controls, recent research illuminates shared and distinct brain structural characteristics compared to other psychiatric diagnoses, and uncovers relations of these brain structures with transdiagnostic symptoms and clinical features. Resting-state functional brain imaging studies reveal disruptions among adolescents and adults with BPD in frontolimbic and default-mode networks, which primarily underlie affect regulation and self-referential processes, respectively. Recent task-based functional brain imaging research builds on existing neurobiological understanding of emotion and cognition in BPD by revealing novel intersections with interpersonal- and stress-related processes. Studies of psychological and pharmacological interventions suggest possible effects on neural regions underlying emotion processing and behavioral control. Recent advances in neurobiological research on BPD underscore the pathophysiology of affective, behavioral and self-interpersonal symptoms, with growing interest in adolescents with BPD and the impacts of psychological and biological interventions. Corresponding with the increased prominence of alternative dimensional models of personality disorder in recent years, there is a gradual rise in studies examining the relationships of brain structures and functional brain activation with BPD-relevant symptom dimensions, including within transdiagnostic samples.

Structural Equation Modeling of Childhood Trauma and Self-Stigma in Adult Inpatients with Borderline Personality Disorder

Purpose

Child abuse and trauma are significant risk factors in the etiology of borderline personality disorder (BPD). Apart from affecting the risk of developing BPD, adverse childhood experiences seem to increase its symptoms and related disability. Self-stigma presents another common issue with equally prominent consequences for mental health. Despite being theoretically linked, the connections among childhood trauma, self-stigma, and mental health have not been explored in patients with BPD. This study aimed to provide first insights into this understudied topic.

Patients and Methods

This cross-sectional study included 283 inpatients diagnosed with BPD participating in a residential transdiagnostic psychotherapeutic program. The patients completed several measurements - the Internalized Stigma of Mental Illness Scale, the Childhood Trauma Questionnaire - Short Form, the Clinical Global Impression - Severity, the Beck Depression Inventory-II, the Beck Anxiety Inventory, the Dissociative Experiences Scale, the Sheehan Disability Scale, and a demographic questionnaire. The data was statistically analyzed using IBM SPSS and AMOS 26 programs, and bivariate correlation tests and structural equation modeling explored the hypotheses.

Results

Retrospectively reported childhood trauma positively correlated with current self-stigma. Both childhood trauma and self-stigma were also positively related to several indicators of general psychopathology and disability. The significance of these connections was subsequently confirmed by structural equation modeling, where self-stigma acted as a partial mediator of childhood trauma, general psychopathology, and disability.

Conclusion

Self-stigma significantly mediates the relationship between childhood trauma and selected mental health symptoms among adult patients diagnosed with BPD. Longitudinal studies are necessary to explore the causality of the findings. Therapeutic and societal efforts to tackle childhood trauma or self-stigma might benefit from reflecting its broader psychosocial context.

The Unified Protocol or Dialectical Behaviour Therapy? Considerations for Choosing Between Two Evidence-Based Transdiagnostic Psychotherapies for Complex Patients

The advent of multiple transdiagnostic treatments in recent decades has advanced the field of clinical psychology while also raising questions for clinicians and patients about how to decide between treatments and how to best deliver a chosen treatment. The purpose of this paper is to review two prominent transdiagnostic treatments that target emotion dysregulation: dialectical behaviour therapy and the unified protocol for transdiagnostic treatment for emotional disorders. First, we review the theoretical underpinnings, research support and proposed mechanisms of action for these treatments. Next, we discuss patient and therapist variables that might indicate which treatment is more appropriate for a given patient and discuss decision-making guidelines to help make this determination with an emphasis on complex patients who may present with risk and/or clinical comorbidities. Finally, we discuss areas for future research that can help further ensure we work to match patients to the treatment that is most likely to benefit them.

A case series of sage: a new couple-based intervention for borderline personality disorder

BACKGROUND

Research suggests that interpersonal dysfunction may be central to borderline personality disorder (BPD), and that the relationships of people with BPD are particularly impaired. Further, the significant others of people with BPD exhibit elevated psychological problems but little access to mental healthcare. Despite this, most BPD interventions are delivered individually and do not routinely incorporate significant others. This manuscript presents the first case series of Sage, a 12-session manualized intervention for people with borderline personality disorder (BPD) and their intimate partners with three targets: a) BPD severity, b) relationship conflict, and c) intimate partner mental health.

FINDINGS

Five couples of people with BPD with frequent suicidal/self-injurious behavior or high suicidal ideation and their intimate partners received Sage. Measures of Sage targets as well as tertiary outcomes were administered at pre-, mid-, and post-intervention. Four out of five dyads completed Sage, with high intervention satisfaction ratings. Improvements were generally demonstrated in BPD severity, suicidal ideation, and suicidal behavior/self-injury. Half of dyads exhibited improvements in conflict, and additional improvements in mental health outcomes for dyad members were demonstrated. One dyad exhibited poor outcomes and speculations regarding this are offered.

CONCLUSIONS

Findings provide proof of concept of Sage as an intervention that can improve BPD and other mental health outcomes in those with BPD and their intimate partners. Incorporating intimate partners into BPD treatment may optimize and expedite its outcomes. However, further testing is needed.

Developmental and Momentary Dynamics in the Onset and Maintenance of Nonsuicidal Self-Injurious Behavior and Borderline Personality Disorder

PURPOSE OF REVIEW

Traditional conceptualizations of both nonsuicidal self-injury (NSSI) and borderline personality disorder (BPD) typically rely on static and unidirectional, linear associations between key biopsychosocial vulnerabilities. Instead, we argue that utilizing a complex dynamic systems view of NSSI and BPD will advance the field, as such conceptual models allow for analysis of bottom-up effects for key vulnerabilities on disorder and behavior emergence, as well as top-down effects of the emergent disorder on underlying vulnerabilities.

RECENT FINDINGS

Following the presentation of a novel framework highlighting momentary and developmental dynamics, we explore several advances in the field that exhibit key dynamic qualities or inform dynamic conceptualizations of NSSI and BPD. At the momentary dynamic level, several advances are being made with multimethod and repeated assessment approaches, as well as advanced bidirectional and complex modeling procedures. Additional progress is being made at the developmental dynamic level, although several questions have arisen regarding the problem of onset and subsequent trajectory, particularly with issues such as pain perception and the interplay between interpersonal, emotional, and behavioral symptoms before and after treatment. Self-injury and BPD both exhibit substantial momentary and developmental dynamics in underlying vulnerabilities, including potential variance in momentary dynamics as a function of psychopathological developmental stage (e.g., onset versus maintenance versus recovery). Recent work has highlighted the necessity of utilizing multimodal research to encapsulate a holistic view of the interplay of several vulnerability factors, the developmental importance of assessment timing, and the need to examine the dynamic interplay between affect, behavior, and interpersonal experiences in BPD and/or NSSI. Research also indicated substantial variation in key vulnerability factors at both between- and within-person levels, highlighting the utility of harnessing statistical models that allow for the simultaneous incorporation of numerous variables at both levels and across several time points. As such, by using a complex dynamic systems conceptualization, we can begin to better understand integrated connections between key vulnerabilities, how they collectively interact in the short term, and how changes in the dynamic interplay between vulnerabilities may arise over the long term and with successful treatment.

MDMA-Assisted Psychotherapy for Borderline Personality Disorder

Borderline personality disorder is a complex psychiatric disorder with limited treatment options that are associated with large heterogeneity in treatment response and high rates of dropout. New or complementary treatments for borderline personality disorder are needed that may be able to bolster treatment outcomes. In this review, the authors comment on the plausibility for research on 3,4-methylenedioxymethamphetamine (MDMA) used in conjunction with psychotherapy for borderline personality disorder (i.e., MDMA-assisted psychotherapy [MDMA-AP]). On the basis of the promise of MDMA-AP in treating disorders overlapping with borderline personality disorder (e.g., posttraumatic stress disorder), the authors speculate on initial treatment targets and hypothesized mechanisms of change that are grounded in prior literature and theory. Initial considerations for designing MDMA-AP clinical trials to investigate the safety, feasibility, and preliminary effects of MDMA-AP for borderline personality disorder are also presented.

Difficulties in interpersonal regulation of emotions (DIRE) questionnaire: Psychometric Properties of the Italian Version and Associations with psychopathological symptoms

The goal of this research was to validate an Italian adaptation of the questionnaire Difficulties in Interpersonal Regulation of Emotions (DIRE) and to investigate its associations with psychopathology. An Italian sample (N = 630) completed the DIRE and the Symptom Checklist-90 (SCL-90). We tested the factorial structure of the DIRE using explorative and confirmatory factorial analyses; we analysed the convergent validity in terms of zero-order correlations with SCL-90 dimensions; and, we conducted multiple regressions to test the predictivity of DIRE factors on specific SCL-90 dimensions. The Italian DIRE replicated the four-factor structure of the original measure, with two interpersonal (Vent and Reassurance-seek) and two intrapersonal (Accept and Avoid) factors. Interpersonal factors resulted correlated with SCL-90 global indexes of psychopathology. Moreover, specific association between DIRE factors and SCL-90 dimensions were found. The Italian DIRE is a reliable and valid measure to evaluate clinically-relevant forms of emotion dysregulation.

Altered immediate behavioral response to partial social exclusion: A cross-diagnostic study in patients with borderline personality disorder and persistent depressive disorder

Borderline personality disorder (BPD) and persistent depressive disorder (PDD) are related to interpersonal dysfunction which might become particularly apparent in situations of social exclusion (SE). While emotional responses to SE have been widely explored, behavioral data in clinical samples are lacking. In this cross-diagnostic study, we applied a variant of the Cyberball paradigm to investigate the dynamic behavioral response to partial SE in BPD and PDD. BPD patients (n = 36), PDD patients (n = 34) and age and gender matched healthy controls (HC) (total n = 70) played experimental (i.e. partial SE Cyberball) and control (i.e. inclusion only) conditions in randomized order. While all groups tended to increase ball tosses towards the excluder in response to SE, this behavioral turn was significantly lower in PDD (p = .03, d = -.30) and trendwise in BPD patients (p = .06, d = -.28). Thus, an altered immediate response to partial SE was observed in BPD and PDD, in addition to the emotional reactions. This study supports the hypothesis of a behavioral coping with SE in BPD and PDD that might be problematic in the long run and provides an experimental paradigm for future research on interpersonal dysfunction.
