A biosocial developmental model of borderline personality: Elaborating and extending Linehan's theory

Comorbid borderline personality disorders in women with post-partum depression admitted to mother-baby units

Borderline personality disorder (BPD) is associated with perinatal depression and parenting difficulties. However, little is known about the characteristics and specific effects of BPD in women with postpartum depression. This study aimed to explore 1) the sociodemographic, mental health characteristics, and motherhood difficulties in women with a major depressive postpartum episode (MDPE) and a comorbid diagnosis of BPD, compared to those with other personality disorders (other PD) or no PD and 2) whether BPD itself may be an independent risk factor for infant neglect in women with a MDPE. 412 women admitted to a Mother and Baby Unit (2001-2010) with a MDPE were involved in this study. Our study showed that women with MDPE-BPD (n = 64) more frequently reported a history of childhood maltreatment, single status, low social support, a history of depression, smoking during pregnancy and suicide attempt during the perinatal period compared to women with other PDs (n = 88) or no PD (n = 260). Women with comorbid BPD had a greater length of stay. Regarding infant care, neglect, abuse, and separation at discharge were more frequent in women with comorbid BPD. Logistic regression was performed to specifically examine whether BPD in women with a MDPE was an independent risk factor for infant neglect during the postpartum period. Comorbid BPD was independently associated with infant neglect (OR = 2.21; CI95% [1.02-4.81]). Our results underline the importance of screening for BPD in women with perinatal depression. Further studies are needed to explore the links between MDPE, BPD, and infant development.

Models predicting the role of emotion reactivity in the link between reasons for not using and lifetime substance use

Objective Substance use peaks in emerging adulthood, with evidence suggesting that college-attending emerging adults have a higher rate of substance use than their non-college attending peers. More insight into the factors that might contribute to substance use among college-attending emerging adults is needed. The current study examined the moderating role of emotion reactivity in the link between perceived importance of reasons for not using substances and lifetime marijuana and alcohol use. Participants: 440 undergraduate students under the age of 21 (M = 18.67, 47.7% Male) from a large Midwestern university participated in the study. Methods Participants responded survey items assessing reasons for not using, lifetime marijuana and alcohol use, and emotion reactivity. Results: Emotion reactivity only moderated the link between reasons for not using alcohol (i.e., reasons related to self-control) and lifetime alcohol use. Conclusions: Future research on reasons for not using is warranted. Implications for preventative interventions are discussed.

Borderline Personality Disorder “Discouraged Type”: A Case Report

Borderline Personality Disorder (BPD) is a mental illness associated with a significant degree of distress and impairment because of the difficulties in effectively regulating emotions. BPD is frequently associated with Depressive Disorders, most commonly Major Depressive Disorder and Dysthymia. Here, we present a case report of an 18-year-old female patient hospitalized with a severe depressive episode and psychotic symptoms. A few months after discharge, the interpersonal difficulties, unstable self-image, fear of chronic abandonment, feeling of emptiness, paranoid ideation, helplessness, obsessive-compulsive elements, perfectionism, and social retreat led to the patient’s impaired functionality. The spectrum of signs and symptoms presented were characteristic of BPD. The specific presentation of mixed dependent/avoidant pattern of personality, with persistent feelings of guilt and shame, social anxiety, emotional attachments, obsessions, and feelings of inadequacy have further narrowed the diagnosis to discouraged BPD, as described by Theodore Millon. In our case, this particular subtype of personality disorder can be understood as BPN associated with social perfectionism. Both BPD and perfectionism, as a trait personality, were thought to exacerbate issues with self-conception and identity formation in this patient.

Relations between lab indices of emotion dysregulation and negative affect reactivity in daily life in two independent studies

BACKGROUND

We investigated the extent to which physiological/biological measures of emotion dysregulation collected in the lab, resting respiratory sinus arrhythmia (RSA) in Study 1 and amygdala activation in response to negative stimuli in Study 2, combined with daily measures of interpersonal stressors predicted negative emotional states in outpatients better than the stressors alone.

METHODS

Participants were adult outpatients with emotional distress disorders (N=30 individuals in Study 1, and N=26 women in Study 2). After completing a laboratory session that collected physiological/biological measures of emotion dysregulation, participants then completed 1-3 weeks of ambulatory assessment during which they reported on interpersonal stressors and negative affective states several times per day.

RESULTS

Laboratory measures of emotion dysregulation were largely unrelated to either momentary or mean levels of daily-life hostility, sadness, and fear in both studies. However, resting RSA significantly moderated the association between day-level interpersonal stressors and momentary fear such that low resting RSA strengthened this association. Similarly, amygdala activation tended to moderate this relationship in the predicted direction.

LIMITATIONS

Both samples were relatively small and focused on only a limited set of diagnoses associated with emotion dysregulation. Only two possible physiological/biological markers of emotion dysregulation were examined.

CONCLUSIONS

The current studies support the collection of physiological/biological data on emotion dysregulation when indexing daily-life emotion dysregulation as the degree of emotional reactivity to stressors in daily life among outpatients with emotional distress disorders.

Perceived Parenting and Borderline Personality Features during Adolescence

This study investigates the associations between perceived parenting and borderline personality disorder (BPD) in adolescents. The relations between components of parenting and BPD features were explored. Participants (N = 270; mean age = 15.3) assessed their own BPD features (Personality Assessment Inventory) and both of their parents' parenting practices (Parents as Social Context Questionnaire; Perceived Parental Autonomy Support Scale). SEM results suggest that controlling, rejecting and chaotic parenting all predicted global BPD, and all these parenting components were significantly associated with at least one BPD feature. Chaotic parenting, a relatively neglected construct in the BPD literature, seems to play an important role in early BPD.

Development and Initial Validation of the Disruptive Mood Dysregulation Disorder Questionnaire Among Adolescents From Clinic Settings

OBJECTIVES

Disruptive mood dysregulation disorder (DMDD) is a new DSM-5 diagnosis. It is observed in youths and is characterized by chronic irritability and temper outbursts. This study aimed (i) to develop a brief questionnaire administered during a semi-structured interview and (ii) to assess its psychometric properties with adolescents 12-15 years old by estimating its internal consistency and its concurrent association with measures of depressive symptoms and borderline personality traits.

METHODS

A 10-item questionnaire was developed based on the DSM-5 criteria and input from mental health professionals. The questionnaire was administered to 192 adolescents from youth centres, inpatient units and specialized outpatient clinics in Montreal, as were the Schedule for Affective Disorders and Schizophrenia for School-Aged Children (K-SADS-PL), the Abbreviated version of the Diagnostic Interview for Borderlines revised (Ab-DIB), and the Dominic Interactive for Adolescents-Revised (DIA-R).

RESULTS

A DMDD Questionnaire among adolescents from clinic settings is obtained. The content of the instrument's items was initially developed based on DSM-5 criteria and expert judgment to ensure that this new instrument covered the theoretical concepts of DMDD in English and French. Twelve participants (6.3%) met nine or more criteria and 11 youths (5.7%) met the three main criteria of DMDD (A, C, and D), which suggested the likely presence of DMDD. The total Cronbach's alpha was 0.90. In addition, the DMDD Questionnaire was significantly associated with depressive symptoms and borderline personality traits.

CONCLUSION

The reliability and concurrent validity indices suggest that the questionnaire as a decision-support tool may be used with adolescents in clinical settings. It highlights that the DSM-5 DMDD criteria seem associated with depressive symptoms and borderline personality traits. Finally, future studies will be necessary to establish more robust calculations in relation to the validity and reliability of this questionnaire.

Heschl's gyrus duplication pattern and clinical characteristics in borderline personality disorder: A preliminary study

Inter-individual variations in the sulco-gyral pattern of Heschl's gyrus (HG) might contribute to emotional processing. However, it remains largely unknown whether borderline personality disorder (BPD) patients exhibit an altered HG gyrification pattern, compared with healthy individuals, and whether such a brain morphological feature, if present, might contribute to their clinical characteristics. The present study used magnetic resonance imaging to investigate the distribution of HG gyrification patterns (single or duplicated) and their relationship to clinical characteristics in teenage BPD patients with minimal treatment exposure. No significant difference was noted for the prevalence of HG patterns between 20 BPD and 20 healthy participants. However, the BPD participants with left duplicated HG were characterized by higher prevalence of comorbid disruptive behavior disorders, with higher externalizing score compared with those with left single HG. Our preliminary results suggest that neurodevelopmental pathology associated with gyral formation might be implicated in the neurobiology of early BPD, especially for emotional and behavioral control.

Neural correlates of emotion acceptance and suppression in borderline personality disorder

BACKGROUND

Emotion dysregulation is a central feature of borderline personality disorder (BPD). Since impaired emotion regulation contributes to disturbed emotion functioning in BPD, it is crucial to study underlying neural activity. The current study aimed at investigating the neural correlates of two emotion regulation strategies, namely emotion acceptance and suppression, which are both important treatment targets in BPD.

METHODS

Twenty-one women with BPD and 23 female healthy control participants performed an emotion regulation task during functional magnetic resonance imaging (fMRI). While watching fearful movie clips, participants were instructed to either accept or to suppress upcoming emotions compared to passive viewing.

RESULTS

Results revealed acceptance-related insular underactivation and suppression-related caudate overactivation in subjects with BPD during the emotion regulation task.

CONCLUSION

This is a first study on the neural correlates of emotion acceptance and suppression in BPD. Altered insula functioning during emotion acceptance may reflect impairments in emotional awareness in BPD. Increased caudate activity is linked to habitual motor and cognitive processes and therefore may accord to the well-established routine in BPD patients to suppress emotional experiences.

A longitudinal investigation of the impact of emotional reactivity and COVID-19 stress exposure on substance use during the pandemic

Background

Substance use has spiked during the COVID-19 pandemic, highlighting potential links between reactivity to pandemic-related stress and increases in substance use engagement. Leveraging population-level exposure to a novel environmental stressor, the current study investigated whether emotion reactivity measured prior to the pandemic predicts the degree to which COVID-related stress impacts future substance use during the pandemic.

Methods

Participants included 240 socioeconomically diverse adults (M/SD_age=33.47/9.39 years old) who were recruited from communities disproportionately impacted by the pandemic, with COVID-19 positivity and unemployment rates higher than the national average. All participants completed a research study prior to the start of the pandemic, and 90 of those participants were randomly selected to complete a follow-up study approximately six months into the pandemic.

Results

On average, the sample reported high levels of stressors that they attributed specifically to the COVID-19 pandemic. Results revealed that trait emotional reactivity moderated the impact of pandemic-inflicted stressors on future substance use, such that COVID-related stress exposure was associated with an increase in substance use for individuals who tend to experience negative emotions for prolonged periods of time.

Limitations

Limitations of the study are that the data were collected in a fixed timeframe of the COVID-19 pandemic and the exclusive use of self-report measures.

Conclusions

The longitudinal design of the present study extends the current literature by highlighting the potential role of emotional reactivity in predicting substance use coping behaviors. Findings suggest that emotion reactivity may be a useful intervention target among individuals highly impacted by the pandemic.

Mattering and Anti-Mattering in Emotion Regulation and Life Satisfaction: A Mediational Analysis of Stress and Distress During the COVID-19 Pandemic

The current study focused primarily on the associations that feelings of not mattering have with life satisfaction, stress, and distress among students trying to cope with the uncertain and novel circumstances brought about by the COVID-19 pandemic. A sample of 350 University students from Italy completed measures that included the General Mattering Scale and the Anti-Mattering Scale, as well as measures of self-esteem, difficulties in emotion regulation, life satisfaction, perceived stress, anxiety, and depression. Psychometric analyses confirmed the factor structure, reliability, and validity of the General Mattering Scale and the Anti-Mattering Scale. As expected, feelings of not mattering were associated with lower life satisfaction as well as with greater reported difficulties in emotion regulation, stress, and distress. Mattering and self-esteem were both unique predictors of levels of life satisfaction during the pandemic. The results of mediational analyses suggested that individuals who feel as though they do not matter may be especially vulnerable to stress, depression, and anxiety and this may promote a decline in life satisfaction. Given the potential destructiveness of feelings of not mattering, in general but especially during a global pandemic, it is essential to proactively develop interventions and programs that are designed to enhance feelings of mattering and reduce anti-mattering experiences and feelings.

The Statistical Specificity of Emotion Dynamics in Borderline Personality Disorder

Persons with borderline personality disorder (BPD) experience heightened emotional instability. Different components underlie instability, and the relation between instability and well-being could be confounded by average emotionality and within-person standard deviation across emotional states, reflecting variability. Therefore, the goal was to examine which pattern of emotion dynamics parsimoniously captures the emotional trajectories of persons with BPD. Forty persons with BPD, 38 clinical controls in a major depressive episode, and 40 healthy controls rated the intensity of their emotions 10 times a day for 1 week. After correction for differences in average emotionality, persons with BPD showed heightened emotional instability compared to both control groups. When additionally correcting for emotional variability, the authors found that instability indices did not differ between groups anymore. This shows that persons with BPD differ from control groups in the magnitude of emotional deviations from the emotional baseline, and not necessarily in the degree of abruptness of these deviations.

Introduction to the Special Issue on Posttraumatic Stress and Suicide

This article introduces this special issue of the Journal of Traumatic Stress devoted to new research investigating the associations among trauma exposure, posttraumatic stress symptoms, and suicidal ideation and behavior. Given the high rates of suicide seen in the aftermath of trauma exposure around the globe, it is important that researchers and clinicians strive to better understand the underlying processes and mechanisms that account for this association and that potentially could be harnessed in intervention and prevention efforts. This opening article introduces the content and themes of the present collection of manuscripts gathered together in this special issue, which includes both conceptual and empirical pieces devoted to the study of suicidality in the context of trauma exposure and considers implications for future research and evidence-based interventions.

Rumination as a widespread emotion-based cognitive vulnerability in borderline personality disorder: A meta-analytic review

OBJECTIVE

The current quantitative review aims at comprehensively clarifying the role of rumination in borderline personality disorder (BPD) considering its relevance for several clinical models of the disorder.

METHOD

This meta-analysis included 29 independent studies assessing different forms of rumination-general tendency to engage in ruminative thinking patterns and four types of emotion-based rumination among both nonclinical subjects reporting BPD features and patients with BPD. Furthermore, the study tested whether rumination could be considered a widespread emotion-based cognitive vulnerability in BPD.

RESULTS

Meta-analytic procedures were based on 46 r coefficients that showed large pooled effect sizes for all forms of rumination. With the exception of interpersonal rumination, the remaining forms of rumination were equally involved in BPD features.

CONCLUSIONS

Rumination should be considered a widespread emotion-based cognitive vulnerability in BPD. Future studies should provide longitudinal and contextual-based evaluations of rumination among treatment-seeking individuals with BPD.

Interpersonal trust in adolescents with psychiatric disorders and borderline pathology

Background:

Adolescents with features of borderline personality disorder (BPD) may experience deficits in interpersonal trust; however, a simultaneous comparison of interpersonal trust among adolescents with BPD, other psychiatric disorders, and no psychiatric conditions (healthy controls) has never been conducted.

Objective:

The aims of this study were to 1) explore differences in interpersonal trust (emotional trust, honesty beliefs, and reliability beliefs) between these three groups, and 2) examine the incremental value of BPD features in association with interpersonal trust over and above internalizing and externalizing.

Method:

Adolescents (N = 445, 67.9% female, M_age = 15.13) recruited from two psychiatric hospitals (psychiatric sample, n = 280) and community organizations (healthy sample, n = 165) completed measures of BPD features, interpersonal trust, and internalizing and externalizing psychopathology. Psychiatric adolescents also completed an interview assessing BPD (n = 83 BPD). ANCOVA and hierarchical linear regression were used for analyses.

Results:

Emotional trust differed significantly across all three groups, with the lowest level of emotional trust in adolescents with BPD. Reliability was also lower in the two psychiatric groups relative to healthy controls. BPD features were significantly, inversely associated with emotional trust and reliability beliefs when controlling for internalizing and externalizing pathology. Post-hoc analyses testing specificity of the three forms of trust found that lower emotional trust predicted BPD diagnosis over and above the other two forms of trust.

Conclusions:

Findings highlight emotional trust as a correlate and important target of intervention for adolescents with BPD, and add to knowledge on interpersonal trust deficits for adolescents with psychiatric disorders more broadly.

Risk of Suicidal Behavior in Children and Adolescents Exposed to Maltreatment: The Mediating Role of Borderline Personality Traits and Recent Stressful Life Events

Childhood maltreatment (CM) is associated with increased non-suicidal self-injury (NSSI) and suicidal behavior (SB), independently of demographic and mental health conditions. Self-Trauma Theory and Linehan's Biopsychosocial Model might explain the emergence of Borderline Personality Disorder (BPD) symptoms as mediators of the association between CM and the risk of SB. However, little is known regarding such relationships when the exposure is recent for young persons. Here, we study 187 youths aged 7-17, with or without mental disorders. We explore CM experiences (considering the severity and frequency of different forms of neglect and abuse), recent stressful life events (SLEs), some BPD traits (emotion dysregulation, intense anger and impulsivity), and the risk of SB (including NSSI, suicide threat, suicide ideation, suicide plan and suicide attempt). We study the direct and mediating relationships between these variables via a structural equation analysis using the statistical software package EQS. Our findings suggest that youths exposed to more severe/frequent CM have more prominent BPD traits, and are more likely to have experienced recent SLEs. In turn, BPD traits increase the risk of SLEs. However, only emotion dysregulation and recent SLEs were found to be correlated with SB. Therefore, targeted interventions on emotion dysregulation are necessary to prevent NSSI or SB in children and adolescents exposed to CM, as is the minimization of further SLEs.

Catastrophizing, negative affectivity, and borderline personality disorder

The core features of borderline personality disorder (BPD) include problematic interpersonal relationships, behavioral and affective dysregulation, identity problems, and cognitive dysregulation. Cognitive dysregulation, such as catastrophizing, rumination, and thought suppression, contributes to emotion dysregulation in BPD. Previous research suggested that thought suppression fully mediated the relationship between negative affect intensity/reactivity and BPD symptoms. We predicted that catastrophizing similarly will serve as a mediator between negative affect intensity/reactivity and BPD symptoms. Two samples completed the study. First, students (N = 191) self-selected to participate in an online study through the university psychology research recruitment system. Additionally, a second sample using Amazon Mechanical Turk (MTurk; N = 172) was utilized. Catastrophizing partially mediated the relationship between negative affect intensity/reactivity and BPD symptoms. Across these samples, results suggest that catastrophizing may have a significant role in understanding BPD symptoms, which is similar with rumination. Limitations and future directions are also discussed.

Borderline personality disorder

Borderline personality disorder (BPD) is a mental disorder with a high burden on patients, family members, and health-care systems. The condition was previously regarded as untreatable, but progress in understanding and management has resulted in earlier diagnosis and better treatment outcomes. A coherent syndrome of BPD typically onsets during adolescence (after age 12 years). BPD is often preceded by or co-develops with symptoms of internalising disorders (depression and anxiety), externalising disorders (conduct problems, hyperactivity, and substance use), or both. BPD is associated with various poor outcomes, including low occupational and educational attainment, lack of long-term relationships, increased partner conflict, sexual risk-taking, low levels of social support, low life satisfaction, and increased service use. Psychotherapy is the main treatment for BPD; drug treatment is only indicated for comorbid conditions that require medication, or during a crisis if psychosocial interventions are insufficient. Awareness of BPD by non-specialists, as well as specialists, is key to appropriate early intervention.

An Examination of Stress Generation and Stress Exposure Models in Relation to Symptoms of Borderline Personality Disorder

Research examining life stress as a precipitant, co-occurrence, and consequence of psychopathology often has implications for two explanatory models: stress exposure, where stress causes symptoms, and stress generation, where symptoms cause stress. Preliminary evidence suggests that both processes are evident in borderline personality disorder (BPD). The present study examined 101 adults who self-reported at least three symptoms of BPD at prescreen, with 30% of the sample meeting full diagnostic criteria for BPD. Cross-lagged panel analyses were used to examine the relationships between BPD symptomatology and four forms of life stress. Stress exposure and stress generation were not supported for either form of chronic life stress. Results supported stress generation in both dependent and interpersonal episodic life stress, and stress exposure for interpersonal episodic life stress. These findings evidenced small effects only. Findings point to the impact of interpersonal stress on changes in symptomatology over time.

Reciprocal effects between daily situational perceptions and borderline personality symptoms in young adulthood: the role of childhood parenting experiences

BACKGROUND

Recent research has emphasized the importance of within-person transactions between situational perceptions and borderline symptomatology. The current study extends current evidence by evaluating a broad range of situational perceptions and their transactions with borderline symptomatology across both private and professional contexts. Additionally, it explores whether early experiences of parental harsh punishment and emotional support during childhood, two well-established etiological factors in developmental theories of borderline symptomatology, influence the effect of daily situation perception in adulthood on borderline symptom presentation.

METHODS

N = 131 young adults (Mage = 20.97, s.d.age = 1.64) completed end-of-day diaries of their borderline symptoms and perceptions of the home and school or work environment for 14 days. During their mid-childhood, reports of maternal strategies of harsh punishment and emotional support were collected.

RESULTS

Findings revealed that on the same day, borderline symptoms were associated with more negative and stressful, and less positive perceptions of both the private and professional context. Additionally, borderline symptoms predicted more negative and stressful perceptions of school/work on subsequent days. Finally, while early harsh punishment predicted overall increases in daily borderline symptoms 10 years later, emotionally supportive parenting in childhood predicted decreases in borderline symptom expression in less positive and more stressful contexts.

CONCLUSIONS

The current study points to the importance of managing BPD symptoms to reduce subsequent negative perceptions of the environment, and also indicates the relevance of exploring adult person-situation processes based on early parenting experiences.

Dialectical Behaviour Therapy Improves Emotion Dysregulation Mainly in Binge Eating Disorder and Bulimia Nervosa: A Systematic Review and Meta-Analysis

Emotion dysregulation is a transdiagnostic phenomenon in Eating Disorders (ED), and Dialectical Behaviour Therapy (DBT) (which was developed for reducing dysregulated emotions in personality disorders) has been employed in patients with ED. This systematic review and meta-analysis investigated whether the effect of DBT was stronger on emotion dysregulation, general psychopathology, and Body Mass Index (BMI) in participants with ED, when compared to a control group (active therapy and waitlist). Eleven studies were identified in a systematic search in accordance with PRISMA guidelines. Most studies included participants with Binge Eating Disorder (BED) (n = 8), some with Bulimia Nervosa (BN) (n = 3), and only one with Anorexia Nervosa (AN). The pooled effect of DBT indicated a greater improvement in Emotion Regulation (ER) (g = −0.69, p = 0.01), depressive symptoms (g = −0.33, p < 0.00001), ED psychopathology (MD = −0.90, p = 0.005), Objective Binge Episodes (OBE) (MD = −0.27, p = 0.003), and BMI (MD = −1.93, p = 0.01) compared to the control group. No improvement was detected in eating ER following DBT (p = 0.41). DBT demonstrated greater efficacy compared with the control group in improving emotion dysregulation, ED psychopathology, and BMI in ED. The limitations included the small number of studies and high variability.

Predicting Non-Suicidal Self-Injury in Young Adults with and without Borderline Personality Disorder: a Multilevel Approach Combining Ecological Momentary Assessment and Self-Report Measures

Non-suicidal self-injury (NSSI) is an increasingly prevalent phenomenon associated with many detrimental outcomes, ranging from poor academic performance to suicide attempts. Research on self-harming behaviors has identified emotion dysregulation, negative affect, and borderline pathology as strong risk factors of NSSI, whereas the potential protective effects of metacognitive skills such as decentering have not yet been explored. The current study combined ecological momentary assessment (EMA) and self-report measures to explore potential risk and protective factors of NSSI in a clinical group of Borderline Personality Disorder (BPD) patients with NSSI (N = 22), a subclinical group of college students with NSSI (N = 19), and a non-clinical healthy control group (N = 23). Participants completed self-report measures of borderline pathology, emotion dysregulation, decentering ability, and negative emotional symptoms, and they used the Sinjur App (EMA instrument) at least three times a day for 15 days to capture negative affect and NSSI in daily life. A multilevel mixed-effect regression analysis with both self-report and EMA measures was conducted to identify predictors of NSSI. The multilevel analysis showed that only momentary frustration directly predicted NSSI. Momentary guilt and anger only predicted NSSI when interacting with more stable traits of borderline pathology and negative emotional symptoms. Most importantly, greater decentering capacity protected against self-injury and attenuated the association between momentary sadness and NSSI. Findings contribute novel knowledge about NSSI, documenting the protective effects of decentering and highlighting the benefit of interventions that target metacognitive emotion regulation skills.

Juror decision-making regarding a defendant diagnosed with borderline personality disorder

Stigma is an established consequence of the Borderline Personality Disorder (BPD) diagnosis. This diagnosis is subject to revision in the International Classification of Diseases-11th Revision (ICD-11). Using the legal issue of diminished responsibility, this study applied an experimental mock-jury methodology to explore the impact of diagnostic stigma of BPD on jury decision-making. Participants were allocated to one of two versions of a simplified fictitious homicide trial. The group whose defendant was described as having a 'severe personality disorder, borderline pattern' rated the defendant as more dangerous, and more in need of segregation and coercive treatment, than controls where the defendant was described as having a 'complex mental health problem'. Between-group differences in other measures, including the decision to agree a verdict of diminished responsibility, were not found. The ICD-11 'severe personality disorder, borderline pattern' diagnosis may adversely impact the attitudes of jurors considering the question of diminished responsibility.

Borderline personality disorder and adolescent suicide attempt: the mediating role of emotional dysregulation

BACKGROUND

Emotional dysregulation seems to be a core feature of Borderline Personality Disorders (BPD). In addition, recent research in the adolescent population has shown that suicidal behaviours have been associated with maladaptive strategies of emotion regulation.

METHODS

This study examined the relative contributions of emotional dysregulation to suicide attempt history in a clinical sample of borderline adolescents. Data were analyzed from 85 participants of the Collaborative European Research Network on Borderline Personality Disorder. Participants completed measures of BPD traits and symptoms, suicide behaviours, emotional dysregulation, attachment styles and lifetime depressive disorders.

RESULTS

In an SEM model, lifetime depressive disorders and insecure attachment styles have a significant direct effect on lifetime suicide attempt, but only lifetime depressive disorders have an indirect effect through emotion dysregulation. The results suggest that emotional dysregulation has a mediating role in suicide attempts among BPD adolescents.

CONCLUSIONS

These findings call for the development of interventions targeting the role of emotion dysregulation in effectively predicting and preventing suicidality in borderline adolescents.

Treatment selection in borderline personality disorder between dialectical behavior therapy and psychodynamic psychiatric management

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.

Borderline Personality Disorder in a "Life History Theory" Perspective: Evidence for a Fast "Pace-of-Life-Syndrome"

"Borderline Personality Disorder" (BPD) is associated with heightened risk for cardiovascular disease and other stress-associated somatic consequences, which is poorly understood in terms of causal mechanisms, such as childhood trauma. Here, we tested the hypothesis suggesting that BPD reflects a fast "Pace-of-Life-Syndrome" (PoLS). Ninety-five women (44 diagnosed with BPD) were recruited to examine psychological correlates of PoLS, including life history features, personality dimensions, aggressiveness, chronic stress, borderline symptom severity, childhood trauma, and allostatic load (AL). In line with expectations, BPD patients had significantly higher scores suggestive of a fast PoLS than controls, they were more aggressive, more burdened with chronic stress and were exposed to more severe childhood adversity. Childhood trauma predicted PoLS, which in turn predicted AL. The present study thus provides direct evidence of psychological and somatic traits associated with the fast end of the PoLS spectrum in females with BPD. Findings are discussed with regard to clinical implications.

Borderline personality disorder (BPD) and attention deficit hyperactivity disorder (ADHD) revisited - a review-update on common grounds and subtle distinctions

BACKGROUND

Overlap in symptom domains particularly in the field of impulsivity and emotional dysregulation in attention deficit hyperactivity disorder (ADHD) and borderline personality disorder (BPD) have stimulated further research activities since our last review from 2014.

MAIN BODY

Disentangling features of impulsivity in ADHD and BPD revealed that impulsivity is a feature of both disorders with patients suffering from both ADHD and BPD having highest impulsivity ratings. BPD individuals have more problems using context cues for inhibiting responses and their impulsivity is stress-dependent, whereas ADHD patients have more motor impulsivity and therefore difficulties interrupting ongoing responses. For emotion regulation difficulties the ranking order ranges from ADHD to BPD to the comorbid condition, again with the patients suffering from both, ADHD and BPD, having the most pronounced emotion regulation problems. Environmental influences namely adverse childhood events were shown to be linked to both ADHD and BPD. Traumatic experiences seem independently linked to impulsivity features. Thus, some authors point to the risk of misdiagnosis during childhood and the necessity to screen for traumatic experiences in both patient groups. Genetic research confirmed genetic overlap of BPD with bipolar disorder (BD) and schizophrenic disorders, as well as genetic overlap of BD and ADHD. A population-based study confirmed the high co-occurrence and familial co-aggregation of ADHD and BPD. Interesting questions in the field of gene-environment-interactions are currently dealt with by genetic and epigenetic research. Few studies have investigated treatment strategies for the comorbid condition, though the issue is highly important for the management of patients suffering from both disorders and presenting with the highest symptom scores.

CONCLUSION

Research on the different impulsivity features might point to a necessity of disorder-specific treatment strategies in the field of impulse control. Future research is needed to base treatment decisions for the comorbid condition on an evidence basis.

Childhood Maltreatment, Borderline Personality Features, and Coping as Predictors of Intimate Partner Violence

Intimate partner violence (IPV) is a serious mental and physical health concern worldwide. Although previous research suggests that childhood maltreatment increases the risk for IPV, the underlying psychological mechanisms of this relationship are not yet entirely understood. Borderline personality (BP) features may play an important role in the cycle of violence, being associated with interpersonal violence in both childhood and adult relationships. The present study investigated whether BP features mediate the relationship between childhood maltreatment and IPV, differentiating between perpetration and victimization, and taking maladaptive stress coping and gender into account. Self-reports on IPV, childhood trauma, BP features, and maladaptive stress coping were collected in a mixed (nonclinical and clinical) sample of 703 adults (n = 537 female, n = 166 male), using an online survey. A serial mediation analysis (PROCESS) was performed to quantify the direct effect of childhood maltreatment on IPV and its indirect effects through BP features and maladaptive coping. Childhood maltreatment severity significantly positively predicted IPV perpetration as well as victimization. BP features, but not coping, partially mediated this relationship. Follow-up analyses suggest that affective instability and interpersonal disturbances (e.g., separation concerns) play an important role in IPV perpetration, while interpersonal and identity disturbances may mediate the effect of childhood maltreatment on IPV victimization. In clinical practice, attention should be paid not only to histories of childhood abuse and neglect but also to BP features, which may be possible risk factors for IPV.

Prediction of Treatment Outcome of Adolescents With Borderline Personality Disorder: A 2-Year Follow-Up Study

This study examined prediction of various clinical outcomes in adolescents with borderline personality disorder (BPD) features. Of the 112 adolescents who participated at baseline, 97 were seen at 2-year follow-up, of which 49 (50.5%) had clinically improved, defined as a decrease in BPD pathology of minimum 12 points on the Borderline Personality Features Scale for Children (BPFS-C). Eighty-one adolescents fulfilled the diagnostic criteria for BPD and scored above clinical cutoff on the BPFS-C at baseline, of which 26 (32%) had remitted at follow-up by self-report on the BPFS-C. Results showed that adolescents with comorbid oppositional defiant disorder at baseline were less likely to have clinically improved or remitted at follow-up. Participants with increased self-reported depression and less exposure to physical abuse at baseline had increased odds of remission. Our findings suggest that more internalizing and less externalizing symptoms increase the odds of positive treatment outcome in adolescents with BPD.

Borderline Personality Disorder: A Case for the Right Treatment, at the Right Dose, at the Right Time

There is now compelling evidence that a range of psychotherapeutic treatments are effective in the treatment of borderline personality disorder (BPD). Such treatments are often lengthy, expensive, subject to high rates of incompletion and are rarely available to people with sub-threshold symptoms. There is broad agreement that some combination of vulnerability, invalidating environment, childhood adversity, disrupted attachment in childhood or trauma play a role in the aetiology of the syndrome of BPD. These factors also contribute to problems with the capacity to mentalise, regulate emotions, tolerate distress and impact on psychosocial development with or without self-damaging and suicidal behaviour. This column takes as a given that people with BPD should receive evidence-based psychological treatments such as dialectical behaviour therapy (DBT), interpersonal therapy and cognitive behavioural therapy in a sufficient dose to be helpful. However, to avert an escalating trajectory which may lead to a diagnosis of BPD the right dose of the right therapy at the right time is necessary. Under-dosing or ineffective psychotherapy can be potentially harmful. This column reviews the evidence, such as it is, for therapeutic approaches which may contribute to more skilful negotiation of life's difficulties and which may avert deterioration in mental health and quality of life in vulnerable individuals and families.

Impact of Childhood Maltreatment in Borderline Personality Disorder on Treatment Response to Intensive Dialectical Behavior Therapy

Childhood maltreatment (CM), including emotional, physical, and sexual abuse and emotional and physical neglect, is associated with severity of borderline personality disorder (BPD). However, knowledge on the impact of CM on treatment response is scarce. The authors investigated whether self-reported CM or one of its subtypes affected treatment retention, depressive symptoms, and impulsivity throughout short-term intensive dialectical behavior therapy (I-DBT) in 333 patients with BPD. Data were analyzed with linear and logistic regressions and linear mixed models, using a Bayesian approach. Patients who reported childhood emotional abuse had a higher dropout rate, whereas it was lower in patients who reported childhood emotional neglect. Emotional neglect predicted a greater decrease of depressive symptoms, and global CM predicted a greater decrease of impulsivity. The authors concluded that patients with BPD who experienced CM might benefit from I-DBT in specific symptom domains. Nonetheless, the impact of emotional abuse on higher dropout needs to be considered.

Positive Affect Is Associated With Decreased Symptom Severity in the Daily Lives of Individuals With Borderline Personality Disorder

Previous research has repeatedly demonstrated positive associations between negative affect (NA) and borderline personality disorder (BPD) symptoms in daily life, but studies have rarely addressed potential effects of positive affect (PA). Consequently, little is known about how PA in daily life covaries with symptoms of BPD. The authors assessed the effects of both PA and NA levels on BPD symptom severity in a sample of 81 treatment-seeking women diagnosed with BPD over a period of 21 days, employing a daily diary design. Using multivariate multilevel modeling, the authors obtained negative associations between PA levels and daily BPD severity in total and at the level of the individual symptoms inappropriate anger, affective instability, emptiness, identity disturbance, and paranoid ideation/dissociation. Moreover, the authors replicated previously reported positive associations between NA and BPD severity for all nine symptoms. Future research can address whether increasing PA in the treatment of BPD may potentially help reduce symptom burden.

A Qualitative Evaluation of Young People's, Parents' and Carers' Experiences of a National and Specialist CAMHS Dialectical Behaviour Therapy Outpatient Service

(1) Background: Dialectical Behaviour Therapy (DBT) is the recommended treatment for Borderline Personality Disorder (BPD) symptoms in adults, however, research investigating the effectiveness of DBT for adolescents is limited. The present study explores the experiences of young people and their parents/carers of a DBT service using qualitative methodology. (2) Methods: Young people and their parents/carers, who completed DBT within the National and Specialist Child and Adolescent Mental Health DBT Service based at the Maudsley Hospital in London, were asked questions regarding their experience of the service. Data was collected from young people who completed treatment between July 2019 and July 2020 (n = 18) and their parents and carers (n = 7). (3) Results: Amongst young people, the themes identified were: a new way of living, better understanding of self, new skills, person-centred approach, and relationships with others. Parent and carer interviews revealed themes of improved relationships, feeling supported, improved quality of life, and time/timing. (4) Conclusions: Young people reported improvements in emerging BPD symptomology after completing DBT. Parents and carers reported improvements in their young person and families since starting DBT. A longer DBT programme, earlier DBT intervention, and the time-consuming nature of DBT were highlighted as areas for improvement.

Unraveling Prospective Reciprocal Effects between Parental Invalidation and Pre-Adolescents' Borderline Traits: Between- and Within-Family Associations and Differences with Common Psychopathology-Parenting Transactions

The etiology of borderline personality pathology has consistently been framed as an interactional process between child vulnerability (i.e. emotional sensitivity and reactivity; Linehan, 1993) and invalidating parenting strategies, which evolves into increased emotion dysregulation and disinhibited behavior of the child and in turn activates more parental invalidation. Despite the strong theoretical base in support of these high-risk parent-child transactions, invalidating parenting behaviors have mostly been explored as a cause of child dysregulation and disinhibition, rather than as a result of child-driven effects. Also, most transactional research in this regard focused at differences between families, thereby not addressing potential changes within families across time. The current study therefore examines bidirectional between- and within-family effects of childhood borderline-related traits and maternal invalidation in the sensitive developmental phase of pre-adolescence (n = 574; 54.4% girls) along three assessment points. Cross-Lagged Panel Models and Random-Intercept Cross-Lagged Panel Models indicated detrimental parenting effects of invalidation on subsequent development in borderline-related traits of the child both between and within families, and additional child-driven effects for subsequent invalidating parenting strategies within families. Beyond these transactions between borderline-related traits and parenting, the current study also indicates significant differences in the direction of effects when exploring transactions between more common dimensions of child internalizing/externalizing symptomatology and parental invalidation, suggesting a more substantial parenting etiology in the developmental process of borderline traits throughout pre-adolescence. Future longitudinal research may explore to what extent the transactional nature of borderline personality traits during important developmental stages indeed holds unique aspects compared to more common manifestations of symptomatology at young age.

Suicide Models and Treatment Models Are Separate Entities. What Does It Mean for Clinical Suicide Prevention?

Theoretical models of suicide are based on risk factors associated with suicide, such as psychiatric pathology, genetics, epigenetics, functional brain disorders, and impaired decision making. In current clinical practice, the predominant risk model is the medical model, which posits that treating suicide risk is primarily a matter of treating psychiatric disorders. However, even comprehensive risk factor models cannot overcome the basic problem that, by their nature, they cannot accommodate the suicidal person's psychological experience of suicidality. Risk factor models do not translate into effective treatment models. Suicide risk is highly personal and fluid, and is related to individual vulnerabilities and to person-specific events triggering suicidal thoughts and actions. Clinicians need treatment models that are meaningful to suicidal patients. Understanding the single person's suicidality requires a patient-centered approach. Therapeutic interventions that effectively reduce the risk of suicidal behavior have been developed from general principles of psychotherapy. Therapy process factors associated with effective therapies are working alliance, validation of the individual patient's thoughts and feelings, active treatment engagement. Psychological therapies need patients who are active participants in a collaborative working relationship between therapist and patient. The goal must be to jointly develop a meaningful understanding of the suicidal crisis. In view of the limited personal resources in health care systems it is important that effective therapies are brief and effective. Future research must aim to improve our understanding of the factors involved in effective therapies in order to optimize treatments for individuals at risk. This may also include the integration of biological risk factors in psychological treatment models.

ADHD and Bipolar Disorder in Adulthood: Clinical and Treatment Implications

Attention deficit hyperactivity disorder (ADHD) is a condition that usually has its onset in childhood. Although the disorder persists into adulthood in half of cases, adult ADHD is often not recognized due to different psychopathological characteristics, quite often overlapping with other diagnoses such as mood, anxiety and personality disorders. This is especially true for bipolar disorder (BD), which shares several symptoms with adult ADHD. Moreover, besides an overlapping clinical presentation, BD is often co-occurring in adults with ADHD, with comorbidity figures as high as 20%. This review will focus on the comorbidity between ADHD and BD by exploring the magnitude of the phenomenon and evaluating the clinical and functional characteristics associated with ADHD-BD comorbidity in adults. Finally, the review will address the implications of pharmacologically treating the ADHD-BD comorbidity, providing suggestions in how to treat these complex patients and addressing the issue of treatment-induced manic switch with the use of stimulants and other medications for ADHD.

Preschool Age Predictors of Adolescent Borderline Personality Symptoms

OBJECTIVE

Developmental models of borderline personality disorder (BPD) have highlighted the interplay of psychological variables (ie, impulsivity and emotional reactivity) with social risk factors, including invalidating parenting and childhood trauma. Prospective longitudinal studies have demonstrated the association of BPD with social, familial, and psychological antecedents. However, to date, few of these studies have studied the interaction of multiple risk domains and their potential manifestations in the preschool period.

METHOD

Participants were 170 children enrolled in a prospective longitudinal study of early childhood depression. Participants completed a baseline assessment between ages 3 and 6 years. Psychopathology, suicidality, and self-harm were assessed using a semistructured age-appropriate psychiatric interview before age 8 and self-report after age 8. BPD symptoms were assessed between ages 14 and 19 by self-report. Adverse childhood experiences (ACEs) and peer relationships were reported by parents. Maternal support was assessed using an observational measure between ages 3 and 6.

RESULTS

Preschool ACEs accounted for 14.9% of adolescent BPD symptom variance in a regression analysis. Controlling for gender and preschool ACEs, preschool and school-age externalizing symptoms, preschool internalizing symptoms, and low maternal support were significant predictors of BPD symptoms in multivariate analyses. Preschool and school-age suicidality composite scores significantly predicted BPD symptoms.

CONCLUSION

These findings suggest that preschool factors may be early predictors of BPD symptoms. Findings demonstrate that preschoolers with internalizing and externalizing psychopathology, high ACEs, and early suicidality are at greater risk of developing BPD symptoms. However, further research is needed to guide key factors for targeted early intervention.

Maternal Emotion Socialization of Adolescent Girls Engaging in Non-Suicidal Self-Injury

Non-suicidal self injury (NSSI) is a transdiagnostic maladaptive behavior that is highly prevalent in adolescence. A greater understanding of the mechanisms leading to NSSI is needed to guide the development of prevention efforts. The current study examined the relationship between maternal socialization of emotions and NSSI behaviors in their children. Female adolescents (N = 90, 12-17 years old) who demonstrated a range of NSSI lifetime episodes from none to very frequent were included in this sample. Maternal responses to their children's displays of sadness, anger, and happiness were assessed. Principal components analysis was used to categorize items into supportive and unsupportive maternal emotion socialization responses for the three emotions. Adolescents whose mothers reported less supportive maternal responses to child's expressions of sadness and anger had more lifetime NSSI episodes. Many of these patterns remained when follow-up analyses considered an extreme group approach (e.g., high counts of NSSI versus no NSSI), when analyses focused on specific diagnostic subgroups (e.g., depression and anxiety), and to some extent (socialization of anger) when current NSSI was considered. While the cross-sectional study design prevents causal conclusions, transactional theories raise the possibility that mothers' emotion socialization may impact offspring NSSI and offspring engagement in NSSI may result in mothers altering their socialization practices to accommodate their child's unique needs. Future research should employ longitudinal methodology to examine the time course, consider the role of emotion regulation as an explanatory mechanism, and consider intervention methods that may teach effective emotion socialization for parents.

Affect-Based Problem Drinking Risk: The Reciprocal Relationship between Affective Lability and Problem Drinking

AIMS

Negative affect has been implicated in risk for the development of problematic drinking behavior. Furthermore, there is evidence for reciprocal relationships between negative affect and problem drinking, such that engagement in problem drinking also predicts increases in negative affect. However, affective models of risk often fail to consider affective lability-the experience of rapidly changing mood. Although affective lability appears to increase risk for problem drinking, it is unknown if this relationship persists above and beyond other affect-related constructs (e.g. depression, anxiety) and if it is reciprocal in nature. Accordingly, we used a longitudinal survey design to examine (a) if affective lability predicts problem drinking above and beyond depression and anxiety and (b) if affective lability and problem drinking demonstrate a reciprocal relationship.

METHODS

First-year college students (n = 358) participated in a three wave longitudinal study. We constructed a structural equation model (SEM) of a random intercept cross-lagged panel model to test our hypotheses.

RESULTS

Consistent with our hypotheses, affective lability predicted increases in problem drinking while anxiety and depression did not. Problem drinking and affective lability demonstrated a reciprocal relationship in which increases in one predicted increases in the other at subsequent time points. This relationship was present beyond the predictive effects of anxiety or depression.

CONCLUSIONS

Affective lability appears to be an important affect-based predictor of problem drinking, and there may be a reciprocal, risk-enhancing relationship between affective lability and problem drinking.Components of negative affect, such as depression or anxiety, have been shown to predict risk for problem drinking, and vice versa. A less considered construct, affective lability, predicted problem drinking while anxiety and depression did not add any predictive power. Problem drinking and affective lability also appeared to demonstrate a reciprocal relationship.

An Emotion Regulation and Impulse Control (ERIC) Intervention for Vulnerable Young People: A Multi-Sectoral Pilot Study

Objective: There is a demonstrated link between the mental health and substance use comorbidities experienced by young adults, however the vast majority of psychological interventions are disorder specific. Novel psychological approaches that adequately acknowledge the psychosocial complexity and transdiagnostic needs of vulnerable young people are urgently needed. A modular skills-based program for emotion regulation and impulse control (ERIC) addresses this gap. The current one armed open trial was designed to evaluate the impact that 12 weeks exposure to ERIC alongside usual care had on young people's ability to regulate emotions, as well as examine potential moderating mechanisms. Methods: Seventy nine young people (50.6% male; M = 19.30; SD = 2.94) were enrolled to the 12 week intervention period. Twenty one practitioners from youth and community health services delivered relevant ERIC modules adjunct to usual care. Linear mixed effects regression (with random intercept) was used to examine change over time across the primary outcome of emotion dysregulation and secondary outcomes of depression, anxiety, stress, experiential avoidance and mindfulness. Moderation analyses were conducted to test whether the magnitude of change in emotion dysregulation moderated change over time in secondary outcomes. Results: Analyses revealed significant improvement in the primary outcome of emotion dysregulation with a moderate effect size (Mean Change = -10.24, 95% CI (-14.41, -6.06; Cohen's dav = -0.53), in addition to decreases in the secondary outcomes of depression, anxiety, stress and experiential avoidance. No improvements in mindfulness were reported. Moderation analyses revealed that the residualised change over time in emotion dysregulation moderated the change over time in symptoms of distress, depression, anxiety, stress, experiential avoidance, and mindfulness. Conclusion: Reductions in the severity of emotion dysregulation, depression, anxiety, stress and experiential avoidance are promising, and were evident despite the complexity of the participants and the diversity of the service setting. The improvements found in each outcome were only observed for those young people whose emotion regulation also improved, providing preliminary evidence for the role of emotion regulation as a key treatment target in this population.

Linking experiences of child sexual abuse to adult sexual intimate partner violence: the role of borderline personality features, maladaptive cognitive emotion regulation, and dissociation

BACKGROUND

Child sexual abuse (CSA) has been linked to a higher risk of sexual re-victimization, including sexual intimate partner violence (IPV). The aim of this study was to investigate whether borderline personality disorder (BPD) features, dissociation, and maladaptive cognitive emotion regulation mediate the link between self-reported CSA severity and sexual IPV. Specifically, we were interested in the unique effect of each mediator variable, when accounting for the effect of the other variables.

METHODS

Data was assessed in a cross-sectional anonymous online survey, posted on platforms for people affected by domestic violence, and research platforms of Leiden University. Overall, n = 633 participants completed the survey (including n = 100 participants with CSA and n = 345 reporting at least one incidence of sexual IPV). Multivariate regression analyses and path-analytical modelling were performed for hypothesis testing.

RESULTS

Adult sexual IPV was predicted by more severe CSA, more severe BPD features, higher dissociation, and more maladaptive emotion regulation. Each mediator variable showed a significant effect in the separate mediation models. In the overall model, only dissociation and maladaptive emotion regulation, but not BPD features, mediated the association between CSA and sexual IPV.

CONCLUSIONS

Findings add to the existing literature, suggesting that CSA severity, BPD features, dissociation, and maladaptive emotion regulation are important risk factors for sexual IPV. Given the cross-sectional correlational design of our study, prospective studies are needed to corroborate our findings regarding potential psychological mechanisms underlying sexual re-victimization. Ultimately, this can help developing interventions aimed at breaking the cycle of abuse.

Challenging control over emotions in borderline personality disorder - a tDCS study

BACKGROUND

Deficient cognitive control (CC) over emotional distraction is a central characteristic of borderline personality disorder (BPD). Reduced activation of the left dorsolateral prefrontal cortex (dlPFC) has been linked to this deficit. This study investigates whether it is possible to ameliorate CC deficits via anodal tDCS over the left dlPFC in BPD. Furthermore, we investigate whether the extent of CC impairment influences how well one responds to tDCS.

METHODS

The effect of a single-session tDCS (1 mA for 20 min, reference electrode on the contralateral mastoid bone) to the left dlPFC (F3) on the CC of patients with BPD (N = 20) and healthy control participants (HCs, N = 20) was examined in a double-blinded, balanced randomized, sham-controlled crossover trial. A delayed response working memory task with negative, neutral and positive pictures presented during the delay period was conducted to assess CC. Stimulation was applied simultaneously with the task.

RESULTS

Negative pictures caused prolonged response times as compared to a control condition in patients with BPD and HCs. Anodal tDCS to the left dlPFC did not significantly reduce this interference effect in the overall sample. Further analyses showed, however, that participants with impaired CC profited the most from anodal tDCS. In the subgroup of participants who actually showed an interference effect we found the expected significant amelioration of CC under tDCS.

CONCLUSIONS

The present study demonstrates that anodal tDCS applied to the left dlPFC improves deficient CC. Thereby, base-level performance moderates tDCS effects. Hence, tDCS might be suitable to support behavioral trainings to enhance CC specifically in people whose impairments in CC are comparably high.

Symptoms as rapidly fluctuating over time: Revealing the close psychological interconnections among borderline personality disorder symptoms via within-person structures

Despite the clinical emphasis on processes happening within individuals, investigations into the psychological, structural connections between mental health symptoms have almost exclusively analyzed differences between people. These investigations have revealed important findings; however, they do not reveal the close connections among symptoms in an individuals' psychology. This study thus examined the psychological connections between symptoms directly, using borderline personality disorder (BPD) symptoms as an example. Participants (252; 74 with BPD) reported their momentary BPD symptoms five times daily, and 165 did so again 18 months later. In support of personalized medicine (Wright & Woods, 2020), individuals' BPD symptom structures differed considerably from each other and from the between-person structure. A novel technique revealed that differences were greater than expected by chance. Within-person structures tended to exhibit more symptom granularity (more factors and lower variance explained) and differing symptom meanings (patterns of loadings). For example, some individuals exhibited close connections between relationship turmoil and identity uncertainty, whereas other individuals exhibited close connections between relationship turmoil and impulsivity. Thus, conceptions of any given person's psychopathological processes using between-person structural findings will most likely be inaccurate.

Interpersonal Problems in Borderline Personality Disorder: Associations With Mentalizing, Emotion Regulation, and Impulsiveness

Interpersonal problems are a core symptom of borderline personality disorder (BPD). This study investigated the relationship between emotion dysregulation, impulsiveness, and impaired mentalizing in the context of predicting interpersonal problems in BPD. A total of 210 patients with BPD completed the Difficulties in Emotion Regulation Scale (DERS), Barratt Impulsiveness Scale (BIS-11), Reflective Functioning Questionnaire (RFQ), and Inventory of Interpersonal Problems (IIP-32). The authors conducted three path models, with either mentalizing, emotion regulation, or impulsiveness as the exogenous variable. Emotion dysregulation and attentional impulsiveness predicted interpersonal problems directly, whereas hypomentalizing predicted interpersonal problems only indirectly throughout emotion dysregulation and attentional impulsiveness. The results suggest that these domains contribute significantly to interpersonal problems in BPD. Moreover, hypomentalizing might affect on interpersonal problems via its effect on impulsiveness and emotion regulation. The authors argue that focusing on emotion regulation and mentalizing in BPD treatments might have interlinked beneficial effects on interpersonal problems.

A Day in the Life of Borderline Personality Disorder: A Preliminary Analysis of Within-Day Emotion Generation and Regulation

In Linehan's (1993) biosocial theory, borderline personality disorder (BPD) results in part from frequent, intense, negative emotions and maladaptive behavioral responses to those emotions. We conducted a secondary data analysis of an intensive single-case experimental design to explore hourly relations among behavioral responses and emotions in BPD. Eight participants with BPD (M _age = 21.57, 63% female; 63% Asian) reported their emotions and behaviors hourly on two days. Participants reported a neutral-to-negative average emotional state with substantial variability each day. This emotional state was characterized most frequently by anxiety and joy. Participants tended to "dig into", or savor, experiences of joy, but problem-solve around, push away, or accept anxiety. Acceptance predicted hour-by-hour increases in negative emotion intensity, and pushing emotions away predicted hour-by-hour increases in positive emotion intensity. These results suggest that anxiety dominates the emotional experiences of people with BPD and co-occurs with a variety of emotion regulation strategies, while joy co-occurs with strategies designed to prolong emotional experiences. Despite its general adaptiveness, acceptance may be less effective, and pushing emotions away may be more effective, than other emotion regulation strategies at improving momentary negative emotions for those with BPD. We discuss the preliminary nature of these findings and encourage future researchers to build on them in larger samples with more severe presentations of BPD.
