Emotion Dysregulation and Trait Anger Sequentially Mediate the Association Between Borderline Personality Disorder and Aggression

Self-disgust in patients with borderline personality disorder. The associations with alexithymia, emotion dysregulation, and comorbid psychopathology

BACKGROUND

Self-disgust is a negative self-conscious emotion, which has been linked with borderline personality disorder (BPD). However, it has not yet been investigated in relation to both emotion dysregulation and alexithymia, which are recognized as crucial to BPD. Therefore, the aim of our study was to measure these variables and examine the possible mediational role of emotional alterations and comorbid anxiety and depression symptoms in shaping self-disgust in patients with BPD and healthy controls (HCs).

METHODS

In total, the study included 100 inpatients with BPD and 104 HCs. Participants completed: the Self-Disgust Scale (SDS), Disgust Scale - Revised (DS-R), Toronto Alexithymia Scale (TAS-20), Emotion Dysregulation Scale short version (EDS-short), Borderline Personality Disorder Checklist (BPD Checklist), State-Trait Anxiety Inventory (STAI), and Center for Epidemiologic Studies Depression Scale (CESD-R).

RESULTS

Inpatients with BPD showed higher self-disgust, alexithymia, emotion dysregulation, core and comorbid symptoms levels, and lower disgust sensitivity. Alexithymia, emotion dysregulation, and trait anxiety partially mediated between BPD diagnosis and self-disgust. The relationship between the severity of BPD symptoms and self-disgust was fully mediated by alexithymia, emotion dysregulation, depressive symptoms, and trait anxiety.

CONCLUSIONS

The results of our study may imply the contribution of emotion dysregulation, alexithymia, and comorbid psychopathology to self-referenced disgust in BPD.

Anger instability and aggression in Borderline Personality Disorder - an ecological momentary assessment study

BACKGROUND

Anger and aggression are core features of Borderline Personality Disorder (BPD), contributing strongly to the individual as well as the societal burden caused by the disorder. Across studies, patients with BPD have shown increased, more frequent and prolonged episodes of anger and reported an increased prevalence of reactive aggression. However, only a few studies have investigated anger and aggression in the patients' everyday lives and did not consider anger instability. In order to contribute knowledge about aggression and its association with anger intensity and anger instability in real-life in BPD the aim of the present study was to better characterize days with and without aggressive behaviors with regard to the patients' experienced anger.

METHODS

Patients with BPD and high aggression as well as healthy participants took part in an ecological momentary assessment (EMA) study assessing state anger and aggression three times per day over two weeks. Multilevel modeling was conducted and anger instability was operationalized by squared successive differences.

RESULTS

As expected, patients with BPD reported greater instability in their experienced anger compared to healthy participants. Most interestingly, in the BPD group the occurrence of aggressive behavior was significantly associated with anger intensity as well as anger instability. More precisely, on days when patients with BPD acted out aggressively, they reported higher anger intensity as well as greater anger instability than on days when they did not act out aggressively.

CONCLUSION

Knowledge about what characterizes days with aggressive behaviors may help to improve interventions to reduce aggressive behavior and thus relieve the burden aggression causes for patients with BPD, their surroundings and society.

A Mechanism-Based Approach to Anti-Aggression Psychotherapy in Borderline Personality Disorder: Group Treatment Affects Amygdala Activation and Connectivity

Aggression is highly prevalent in borderline personality disorder (BPD). Previous studies have identified specific biobehavioral mechanisms underlying aggression in BPD, threat sensitivity being among them. We composited the mechanism-based anti-aggression psychotherapy (MAAP) in order to target these specific mechanisms, and MAAP was found to be superior to non-specific supportive psychotherapy (NSSP) in reducing aggressive behavior. In the present study, we investigated whether underlying brain mechanisms expected to be involved were affected by MAAP. To this end, n = 33 patients with BPD and overt aggressive behavior (n = 20 in MAAP, n = 13 in NSSP) and n = 25 healthy participants took part in a functional magnetic resonance imaging emotional face-matching task before and after treatment, or at a similar time interval for controls. Overt aggressive behavior was assessed using the overt aggression scale, modified. Results showed a decrease in amygdala activation in response to facial stimuli after MAAP, whereas an increase in amygdala activation was found after NSSP. Furthermore, in the MAAP group, connectivity between amygdala and dorsomedial prefrontal cortex increased from pre- to post-treatment compared to the NSSP group. Hence, the results suggest an impact of MAAP on brain mechanisms underlying the salience circuit in response to threat cues.

The dual mediating roles of impulsivity and emotion regulation of the borderline personality disorder-violence relationship: A structural equation modeling approach

Although the past research has indicated that features of borderline personality disorder (BPD) increase the risk for violence, much less research has examined the mediators of this relationship. This study examined the mediating roles that impulsivity and emotion dysregulation may play in explaining the relationship between BPD and violence. The Pathways to Desistance data were used in analyses. Generalized structural equation modeling was used to estimate the direct effect of BPD features on violent offending risk and to examine the mediating roles of emotion dysregulation and impulsivity. Results indicated that the direct effect of BPD symptoms on violence was mediated to non-significance by key constructs, and the magnitude of the effect was reduced by around 40%. The total indirect effect was significant, and the mediation was attributed mainly to impulsivity. This indicates the importance of structuring treatment programming for BPD patients around impulsivity for reducing violence. Programming focused on improving impulsivity among individuals suffering from BPD may aid in reducing violent offending among this population, particularly those prior histories of involvement with the criminal justice system.

Don't Make Me Angry: Frustration-Induced Anger and Its Link to Aggression in Women With Borderline Personality Disorder

Aggression is a prominent interpersonal dysfunction of individuals with borderline personality disorder (BPD). In BPD aggression is predominantly reactive in nature, often triggered by frustration, provocation, or social threat and is associated with intense anger and an inability to regulate this strong, negative emotion. Building on previous research, we were interested in investigating negative emotionality in general and anger in particular in women with BPD before and after frustration induction. To achieve this, 60 medication-free women with BPD and 32 healthy women rated the intensity of negative emotions (angry, frustrated, upset, embarrassed, nervous) before and after performing a Titrated Mirror Tracing Task, which reliably induces frustration and distress. As expected, women with BPD reported significantly greater intensity of negative emotions before and after frustration than healthy women. Specifically, they showed a significantly stronger frustration-induced increase in anger, while other negative emotions remained unaffected by frustration induction. This anger increase was significantly related to aggressive behavior reported in the 2 weeks prior to the experiment, as well as to the level of frustration experienced in the experiment itself, but not with emotion dysregulation. The current data confirm the important role of frustration-induced anger independent of emotion dysregulation in BPD, in particular with regard to aggression, a prominent interpersonal dysfunction of this disorder. These findings underline the importance of interventions with particular focus on anger.

Emotional Dysregulation in Children and Adolescents With Psychiatric Disorders. A Narrative Review

Background: Emotional dysregulation (ED) is a transdiagnostic construct defined as the inability to regulate the intensity and quality of emotions (such as, fear, anger, sadness), in order to generate an appropriate emotional response, to handle excitability, mood instability, and emotional overreactivity, and to come down to an emotional baseline. Because ED has not been defined as a clinical entity, and because ED plays a major role in child and adolescent psychopathology, we decided to summarize current knowledge on this topic based on a narrative review of the current literature. Methods: This narrative review is based on a literature search of peer-reviewed journals. We searched the databases ERIC, PsycARTICLES, PsycINFO and PSYNDEX on June 2, 2020 for peer reviewed articles published between 2000 and 2020 in English language for the preschool, school, and adolescent age (2-17 years) using the following search terms: "emotional dysregulation" OR "affect dysregulation," retrieving 943 articles. Results: The results of the literature search are presented in the following sections: the relationship between ED and psychiatric disorders (ADHD, Mood Disorders, Psychological Trauma, Posttraumatic Stress Disorder, Non-suicidal Self-Injury, Eating Disorders, Oppositional Defiant Disorder, Conduct Disorder, Disruptive Disruptive Mood Dysregulation Disorder, Personality Disorders, Substance Use Disorder, Developmental Disorders, Autism Spectrum Disorder, Psychosis and Schizophrenia, and Gaming Disorder), prevention, and treatment of ED. Conclusion: Basic conditions of ED are genetic disposition, the experience of trauma, especially sexual or physical abuse, emotional neglect in childhood or adolescence, and personal stress. ED is a complex construct and a comprehensive concept, aggravating a number of various mental disorders. Differential treatment is mandatory for individual and social functioning.

A mechanism-based group-psychotherapy approach to aggressive behaviour in borderline personality disorder: findings from a cluster-randomised controlled trial

BACKGROUND

Aggressive behaviour is a prevalent and harmful phenomenon in patients with borderline personality disorder (BPD). However, no short-term, low-cost programme exists that specifically focuses on aggression.

AIMS

Attuning therapy modules to pathogenetic mechanisms that underlie reactive aggression in BPD, we composed a 6 week mechanism-based anti-aggression psychotherapy (MAAP) approach for the group setting, which we tested against a non-specific supportive psychotherapy (NSSP).

METHOD

A cluster-randomised two-arm parallel-group phase II trial of N = 59 patients with BPD and overt aggressive behaviour was performed (German Registry for Clinical Trials, DRKS00009445). The primary outcome was the externally directed overt aggression score of the Modified Overt Aggression Scale (M-OAS) post-treatment (adjusted for pre-treatment overt aggression). Secondary outcomes were M-OAS irritability, M-OAS response rate and ecological momentary assessment of anger post-treatment and at 6 month follow-up, as well as M-OAS overt aggression score at follow-up.

RESULTS

Although no significant difference in M-OAS overt aggression between treatments was found post-treatment (adjusted difference in mean 3.49 (95% CI -5.32 to 12.31, P = 0.22), the MAAP group showed a clinically relevant decrease in aggressive behaviour of 65% on average (versus 33% in the NSSP group), with particularly strong improvement among those with the highest baseline aggression. Most notably, significant differences in reduction in overt aggression between MAAP and NSSP were found at follow-up.

CONCLUSIONS

Patients with BPD and aggressive behaviour benefited from a short group psychotherapy, with improvements particularly visible at 6 month follow-up. Further studies are required to show whether these effects are specific to MAAP.

Change in core symptoms of borderline personality disorder by tDCS: A pilot study

Borderline personality disorder (BPD) recognizes several psychopathological dimensions related to prefrontal cortex impairments. Transcranial Direct Current Stimulation (tDCS) targeting the right prefrontal dorsolateral cortex (DLPFC) positively influence cognitive functions related to impulsivity in healthy subjects. A randomized double-blind study was designed to investigate whether tDCS could modulate core dimensions (impulsivity, aggression, affective dysregulation) of BPD. Also effects on decision making process and substances craving was assessed. Patients were randomized to receive active-tDCS at 2 mA versus sham-tDCS, once a day for 15 sessions. Anode was placed on the right DLPFC (F4), cathode on the left DLPFC (F3). Impulsivity and aggression measures were significantly reduced only in patients treated with active-tDCS. Decision-making process was marginally influenced by the active current. Craving intensity was reduced only in the active-tDCS sample. Both groups showed improvements in the affective dysregulation dimension and anxious and depressive symptoms. The application of bilateral tDCS targeting right DLPFC with anodal stimulation seems to improve core dimensions of BPD (mainly impulsivity and aggression) probably by restoring prefrontal activity. tDCS might be a potential tool for preventing self-harming behaviors.

Pharmacological Approaches to Managing Violence and Aggression in Prison Populations: Clinical and Ethical Issues

Violence and aggression are common problems encountered in prison, which frequently require clinical intervention. This increased prevalence is partially attributable to the high morbidity of psychiatric and personality disorders in prison inmates. As prisons are non-therapeutic environments, the provision of clinical care becomes more complex. This article examines the general principles of management of violence and aggression in prison settings, with a particular focus on the clinical and ethical considerations that guide pharmacological approaches. Use of psychotropic medication to address these problems is reserved for situations where there is (i) a diagnosable psychiatric disorder, or (ii) a significant risk of harm to an individual without urgent intervention. Initial focus should be on environmental and behavioural de-escalation strategies. Clear assessment for the presence of major mental illness is crucial, with appropriate pharmacological interventions being targeted and time-limited. Optimising management of any underlying psychiatric conditions is an important preventative measure. In the acute setting, rapid tranquilisation should be performed according to local guidelines with a focus on oral prior to parenteral administration. Clinicians must be mindful of capacity and consent issues amongst prisoners to protect patient rights and guide setting of care.

The Sacred Power of Beauty: Examining the Perceptual Effect of Buddhist Symbols on Happiness and Life Satisfaction in China

The theoretical relationship between Buddhism and subjective well-being has gained much academic attention in recent decades. However, the prominent determinants of religiosity remain limited for researchers to understand a holistic picture of religion-informed subjective well-being, particularly in the context of Buddhism. This study has applied a quantitative survey to verify the impact of the aesthetic effects of the Buddhist gesture symbol on Chinese people’s subjective happiness through sequential mediators of life satisfaction and the perceived religiosity. The significance of this study is threefold. Firstly, it aims to enrich the current academic understanding of the religion-informed subjective well-being by introducing a new determinant of the Buddhist symbols. Secondly, the current study investigates the mechanism of how Buddhist symbols could influence happiness by analyzing the sequential mediating roles of religiosity and life satisfaction. Thirdly, this study empirically examines the topic in the context of China to confirm and underpin the theoretical relationship between Buddhism and subjective well-being in relevant research, which has previously focused on Western culture. Our results indicated that the aesthetic perception of the Buddhist gesture symbol positively influenced perceived happiness and life satisfaction. In addition, perceived religiosity and life satisfaction sequentially mediated the perceived happiness after seeing the Buddhist gesture symbol. Our findings contribute to the current academic understanding of religious symbols and their impacts on subjective well-being.

The Roles of Emotion Regulation Difficulties and Impulsivity in the Associations between Borderline Personality Disorder Symptoms and Frequency of Nonprescription Sedative Use and Prescription Sedative/Opioid Misuse

Despite evidence of a strong relationship between BPD and substance use problems in general, little research has examined the associations of BPD symptoms with the misuse of sedatives or opioids, and no studies have explored possible factors that may underlie these associations. Thus, this study examined the relationships of BPD symptoms (i.e., the number of BPD criteria with threshold ratings on a diagnostic interview) to nonprescription sedative use, nonprescription opioid use, and prescription sedative/opioid misuse among 194 patients with alcohol and/or cocaine dependence in a residential substance use disorder treatment facility, as well as the roles of two theoretically-relevant factors in these relationships: emotion regulation (ER) difficulties and impulsivity facets. We found significant positive associations between BPD symptoms and nonprescription sedative use, nonprescription opioid use, and prescription sedative/opioid misuse. We also found significant positive indirect relationships of BPD symptoms to nonprescription sedative use through ER difficulties, ab = .04, 95% CI [.003, .09], and to prescription sedative/opioid misuse through two facets of impulsivity: lack of perseverance, ab = .05, 95% CI [.01, .11], and negative urgency, ab = .03, 95% CI [.002, .07]. Findings highlight the differential relevance of ER difficulties and impulsivity dimensions to the relationships of BPD symptoms to nonprescription sedative use and prescription sedative/opioid misuse, respectively, among patients with alcohol and/or cocaine dependence.

Covariates of the Severity of Aggression in Sexual Crimes: Psychopathy and Borderline Characteristics

Whereas risk assessment literature on sexual offending has primarily focused on prediction of subsequent sexual crimes, and not the severity of those crimes, the first aim of the present study was to identify variables that predict the amount of damage to victims in sexual crimes compared with those that predict general aggressiveness. The second aim was to ascertain whether adding emotional instability measurements, as in borderline personality disorder (BPD), would add incremental variance to that captured by the facets of the Psychopathy Checklist-Revised (PCL-R). Trained raters assessed on the PCL-R, BPD, and measures of severity of sexual and nonsexual violence 302 adults who had sexually offended. PCL-R's Antisociality and two externalizing BPD factors (one from the standard and one from the alternative criteria) were significant predictors of violence both in sexual and nonsexual crimes. In contrast, deficits in the PCL-R's Affective facet (2) predicted victim damage in sexual contexts only, whereas the Lifestyle Impulsivity facet (3) of the PCL-R predicted violence in nonsexual contexts only. These findings suggest that adding measures of emotional dysregulation to commonly used instruments like the PCL-R, which assesses callousness and antisociality, may be beneficial for predicting violence.

Differential effects of the menstrual cycle on reactive and proactive aggression in borderline personality disorder

Borderline personality disorder (BPD) is characterized by rapidly shifting symptoms, including intense anger and aggressive behavior. Understanding how fluctuations in ovarian hormones across the menstrual cycle may contribute to symptom instability is key for accurate assessment of BPD symptoms and effective interventions. Reactive and proactive aggression, as well as anger-in and anger-out, were assessed daily in 15 physically healthy, unmedicated naturally cycling female individuals meeting criteria for BPD across 35 days. Urine luteinizing hormone surge and salivary progesterone were used to confirm ovulation and verify the cycle phase. Multilevel models evaluated cyclical differences of symptoms between cycle phases. Both forms of aggressive behavior demonstrated marked cycle effects, with reactive aggression highest during the midluteal cycle phase, co-occurring with initial increases in anger and irritability and followed by perimenstrual peaks in anger and anger-in. In contrast, highest levels of proactive aggression were observed during the follicular and ovulatory phases, when emotional symptoms and anger were otherwise at lowest levels. These findings highlight the importance of identifying the function of aggression when considering potential psychological and biological influences. Naturally cycling individuals with BPD may be at elevated risk for luteal worsening of a range of interpersonally reactive symptoms, including reactive aggression, whereas proactive aggression may occur more in phases characterized by less emotional and cognitive vulnerability and greater reward sensitivity. Research on aggression in this population should consider cycle effects. Cycling individuals with BPD attempting to reduce aggressive behavior may benefit from cycle-tracking to increase awareness of these effects and to develop appropriate strategies.

Specific or transdiagnostic? The occurrence of emotions and their association with distress in the daily life of patients with borderline personality disorder compared to clinical and healthy controls

Borderline personality disorder (BPD) is characterized by more frequent and more intense negative emotions and less frequent positive emotions in daily life than healthy controls (HC) experience, but there is limited empirical evidence regarding whether this is a transdiagnostic or disorder-specific finding and which specific emotions are especially distressing in BPD. We assessed participants' current emotions and distress every 15 min over a 24-h period using e-diaries to investigate the frequency, intensity, and the associated distress of specific emotions. To test the disorder specificity, we used multilevel modeling to compare 43 female patients with BPD, 28 patients with posttraumatic stress disorder (PTSD), 20 patients with bulimia nervosa (BN), and 28 HC. Patients with BPD exhibited anger more frequently than any of the clinical or healthy control groups, demonstrating specificity. The quality of anger accounted for additional distress beyond the pure emotional intensity. In patients with BPD, joy was associated with reduced distress, which was not the case in HC or PTSD. However, the majority of the comparisons (anxiety, sadness, shame, disgust, jealousy, guilt, interest) revealed transdiagnostic patterns. The distress-enhancing or distress-reducing effects of anger and joy might represent an important part of affective dysregulation in BPD.

Understanding Brain Mechanisms of Reactive Aggression

PURPOSE OF REVIEW

To review the current literature on biobehavioral mechanisms involved in reactive aggression in a transdiagnostic approach.

RECENT FINDINGS

Aggressive reactions are closely related to activations in the brain's threat circuitry. They occur in response to social threat that is experienced as inescapable, which, in turn, facilitates angry approach rather than fearful avoidance. Provocation-induced aggression is strongly associated with anger and deficits in cognitive control including emotion regulation and inhibitory control. Furthermore, the brain's reward system plays a particular role in anger-related, tit-for-tat-like retaliatory aggression in response to frustration. More research is needed to further disentangle specific brain responses to social threat, provocation, and frustration. A better understanding of the psychological and neurobiological mechanisms involved in reactive aggression may pave the way for specific mechanism-based treatments, involving biological or psychotherapeutic approaches or a combination of the two.

Impulsivity issues in borderline personality disorder and it's links with insight: the role of urgency

Objective

Impulsivity plays a major role in a wide range of disorders including Borderline Personality Disorder. Another crucial clinical dimension is insight. This clinical dimension is linked with symptomatology and treatment issue. The present study aims to investigate the impact of positive and negative urgency on insight in Borderline Personality Disorder.

Methods

We recruited eighty-one women with Borderline Personality Disorder and assessed insight level and impulsivity scores using the Beck Cognitive insight scale and the UPPS-short form scale.

Results

Our results showed interesting links between positive urgency and insight quality.

Conclusion

Negative emotions play a fundamental role for the insight quality, but positive emotions are surprisingly related to clinical insight. We discuss the possible therapeutical impact of this results on treatment adaptation.

Respiratory Sinus Arrhythmia Mediates Links Between Borderline Personality Disorder Symptoms and Both Aggressive and Violent Behavior

Although emotion dysregulation (ED) is a core symptom of borderline personality disorder (BPD), tests of associations between ED and aggression and violence-which are common to BPD-are sparse. The authors evaluated mediating effects of an autonomic vulnerability to ED on links between BPD symptoms and (a) reactive aggression, (b) proactive aggression, and (c) histories of interpersonal violence in a sample of young adults (N = 104), ages 18-22 years. Low baseline respiratory sinus arrhythmia (RSA) mediated the association between BPD symptoms and reactive aggression. In contrast, although BPD symptoms were correlated with proactive aggression, no mediational effect was found. In addition, low RSA mediated the association between BPD symptoms and histories of interpersonal violence. Collectively, these findings add evidence that neurobiological vulnerability to ED contributes to aggressive and violent behavior among those with BPD.

Whole-brain functional connectivity during script-driven aggression in borderline personality disorder

OBJECTIVE

Intense anger and anger-related aggression are frequently reported by patients with borderline personality disorders (BPD). Recent results suggest that anger-related aggression and its control is associated with a complex interplay of different neural systems in BPD. To further investigate this, we complement standard activation and seed-based connectivity analyses by examining whole-brain changes in functional connectivity during anger and reactive aggression in BPD.

METHODS

We reanalyzed functional MRI data from 33 women with BPD, all of them fulfilling BPD criterion 8, "anger proneness", according to DSM-IV, and 30 healthy women. Subjects performed a script-driven imagery task consisting of four phases: baseline, anger-induction by a narrative of interpersonal rejection, a narrative of directing physical aggression towards others, and relaxation. We used a data-driven, spatially constrained spectral clustering approach to parcellate the brain into 200 regions. For each script-phase and subject, we computed the full connectivity matrix using wavelet coefficient correlations in the 0.05-0.10 Hz range. We calculated the individual increase in connectivity from baseline to the anger-induction and physical aggression phases by subtracting the corresponding connectivity matrices per subject, as well as the increase and decrease from the anger-induction to the aggression phase. We then applied permutation-based sampling to determine a combined threshold on the strength of individual connections and the size of the discovered networks for these difference matrices.

RESULTS

We discovered a single, large network showing a significantly stronger increase in connectivity from baseline to the aggression phase in female patients with BPD compared to healthy women. This network consisted of regions in the anterior and posterior cingulate cortex, precuneus, dorsomedial prefrontal cortex, superior and middle temporal gyrus, hippocampus, insula, ventrolateral and dorsolateral prefrontal cortex, superior parietal lobe, thalamus, precentral and postcentral gyrus, caudate, pallidum, cerebellum, middle occipital lobe, lingual gyrus, calcarine sulcus, and fusiform gyrus. Hub regions with highest node centrality were found in the right caudate and left thalamus. We found no significant differences for the increase of connectivity from baseline to anger-induction, as well as for the increase or decrease from the anger-induction to the aggression phase.

CONCLUSIONS

We identified a large network showing a significantly stronger increase in connectivity from baseline to the aggression phase in female patients with BPD compared to healthy women. The regions constituting this network belong to four previously described functional networks: The frontoparietal cognitive control network, the extended default mode network, the visual system, and the motor system. This stronger increase in connectivity between regions of different functional brain systems associated with cognitive control of behavior, socio-affective and self-referential thinking, as well as salience processing and emotion regulation, visual perception, and action is mediated via hubs in the thalamus and caudate, i.e., core components of the thalamocorticostriatal motor loop essential for action selection and initiation. These findings suggest increased interaction of prefrontal cognitive control processes with thalamocorticostriatal action-selection processes in female patients with BPD during the processing of aggressive action impulses, which are facilitated by states of high emotional salience and associated processes of self-referential and social processing, and ineffective emotion regulation.

Correlates of Aggression in Personality Disorders: an Update

PURPOSE OF REVIEW

This review article aims at giving an update on studies investigating correlates of aggression in personality disorders during the last 5 years.

RECENT FINDINGS

Most data refer to borderline personality disorder (BPD) and antisocial personality disorder (ASPD). In BPD, emotion dysregulation, hypersensitivity to interpersonal rejection/threat, increased rumination, increased negative urgency, aggression-related knowledge structures, and invalidation were either corroborated or emerged as psychological correlates of aggression, while reduced ambiguity sensitivity, hyposensitivity to interpersonal threat, and reduced mindfulness were associated with aggression in ASPD. Neurobiologically, alterations of the monoaminooxidase-A-, the oxytocinergic-, and the prefrontal-limbic-system as well as increases of the thyroid hormone T3, γ-aminobutyric acid and several inflammatory markers were associated with increased aggression across various personality disorders. Our understanding of correlates of aggression in personality disorders has increased over the last 5 years. More efforts in improving the conceptualization of personality disorders and aggression are needed to develop innovative treatments for those affected.

Emotional neglect in childhood shapes social dysfunctioning in adults by influencing the oxytocin and the attachment system: Results from a population-based study

Early life maltreatment (ELM) is the major single risk factor for impairments in social functioning and mental health in adulthood. One of the most prevalent and most rapidly increasing forms of ELM is emotional neglect. According to bio-behavioral synchrony assumptions, the oxytocin and attachment systems play an important mediating role in the interplay between emotional neglect and social dysfunctioning. Therefore, the aim of the present study was to investigate whether fear and avoidance of social functioning, two important and highly prevalent facets of social dysfunctioning in adulthood, are shaped by emotional neglect, plasma oxytocin levels and attachment representations. We assessed emotional neglect as well as other forms of ELM with the Childhood Trauma Questionnaire, current attachment representations with the Adult Attachment Projective Picture System, and fear and avoidance of social situations with the Liebowitz Social Anxiety Scale in a population-based sample of N = 121 men and women. Furthermore, 4.9 ml blood samples were drawn from each participant to assess peripheral plasma oxytocin levels. Applying a sequential mediation model, results revealed that emotional neglect was associated with lower plasma oxytocin levels which in turn were associated with insecure attachment representations which were related to elevated fear and avoidance of social situations (a₁d₂₁b₂: F_3,117 = 20.84, P < .001). Plasma oxytocin and current attachment representations hence fully and sequentially mediate the effects of emotional neglect on social fear and avoidance, two important facets of adult social dysfunctioning, confirming bio-behavioral synchrony assumptions.

Heightened Salience of Anger and Aggression in Female Adolescents With Borderline Personality Disorder-A Script-Based fMRI Study

Background: Anger and aggression belong to the core symptoms of borderline personality disorder. Although an early and specific treatment of BPD is highly relevant to prevent chronification, still little is known about anger and aggression and their neural underpinnings in adolescents with BPD.

Method: Twenty female adolescents with BPD (age 15–17 years) and 20 female healthy adolescents (age 15–17 years) took part in this functional magnetic resonance imaging (fMRI) study. A script-driven imagery paradigm was used to induce rejection-based feelings of anger, which was followed by descriptions of self-directed and other-directed aggressive reactions. To investigate the specificity of the neural activation patterns for adolescent patients, results were compared with data from 34 female adults with BPD (age 18–50 years) and 32 female healthy adults (age 18–50 years).

Results: Adolescents with BPD showed increased activations in the left posterior insula and left dorsal striatum as well as in the left inferior frontal cortex and parts of the mentalizing network during the rejection-based anger induction and the imagination of aggressive reactions compared to healthy adolescents. For the other-directed aggression phase, a significant diagnosis by age interaction confirmed that these results were specific for adolescents.

Discussion: The results of this very first fMRI study on anger and aggression in adolescents with BPD suggest an enhanced emotional reactivity to and higher effort in controlling anger and aggression evoked by social rejection at an early developmental stage of the disorder. Since emotion dysregulation is a known mediator for aggression in BPD, the results point to the need of appropriate early interventions for adolescents with BPD.

Grandiose and Vulnerable Narcissism in Borderline Personality Disorder

BACKGROUND

Little is known about narcissistic traits in borderline personality disorder (BPD). This exploratory study aimed to illustrate the associations between total, grandiose, and vulnerable narcissism and gender, diagnostic features of BPD and narcissistic personality disorder (NPD), and psychopathology in BPD patients.

SAMPLING AND METHODS

The Pathological Narcissism Inventory and psychometric measures for impulsivity, anger, borderline symptom severity, personality organization, depression, and rejection sensitivity were completed by 65 BPD patients. Statistical analyses were conducted using the t test, Pearson correlation, and multivariate regression analyses.

RESULTS

Male BPD patients displayed higher narcissistic scores than females (p < 0.01). Grandiose narcissism showed a stronger association with NPD than with BPD (p < 0.01) while vulnerable narcissism was only associated with BPD (p < 0.01). Rejection sensitivity (p < 0.01) and depression (p < 0.001) predicted vulnerable narcissism.

CONCLUSION

Vulnerable narcissism is closely associated with BPD and appears to be more dysfunctional than grandiose narcissism. A comprehensive consideration of both traits is recommended. Our results might help to generate hypotheses for further research on pathological narcissism in the spectrum of personality disorders. Future studies are advised to apply complementary measures and take new diagnostic approaches of DSM-5 and ICD-11 into account.

Deliberate self-harm behavior among young violent offenders

Deliberate self-harm behavior (DSH) can have profound effects on a person's quality of life, and challenges the health care system. Even though DSH has been associated with aggressive interpersonal behaviors, the knowledge on DSH in persons exhibiting such behaviors is scarce. This study aims to (1) specify the prevalence and character of DSH, (2) identify clinical, neurocognitive, psychosocial, and criminological characteristics associated with DSH, and (3) determine predictors of DSH among young violent offenders. Data were collected from a nationally representative cohort of 270 male violent offenders, 18-25 years old, imprisoned in Sweden. Participants were interviewed and investigated neuropsychologically, and their files were reviewed for psychosocial background, criminal history, mental disorders, lifetime aggressive antisocial behaviors, and DSH. A total of 62 offenders (23%) had engaged in DSH at some point during their lifetime, many on repeated occasions, yet without suicidal intent. DSH was significantly associated with attention deficit hyperactivity disorder, mood disorders, anxiety disorders, various substance use disorders, being bullied at school, and repeated exposure to violence at home during childhood. Mood disorders, anxiety disorders, and being bullied at school remained significant predictors of DSH in a total regression model. Violent offenders direct aggressive behaviors not only toward other people, but also toward themselves. Thus, DSH must be assessed and prevented in correctional institutions as early as possible, and more knowledge is needed of the function of DSH among offenders.

Brain Mechanisms Underlying Reactive Aggression in Borderline Personality Disorder-Sex Matters

BACKGROUND

Aggression in borderline personality disorder (BPD) is thought to be mediated through emotion dysregulation via high trait anger. Until now, data comparing anger and aggression in female and male patients with BPD have been widely missing on the behavioral and particularly the brain levels.

METHODS

Thirty-three female and 23 male patients with BPD and 30 healthy women and 26 healthy men participated in this functional magnetic resonance imaging study. We used a script-driven imagery task consisting of narratives of both interpersonal rejection and directing physical aggression toward others.

RESULTS

While imagining both interpersonal rejection and acting out aggressively, a sex × group interaction was found in which male BPD patients revealed higher activity in the left amygdala than female patients. In the aggression phase, men with BPD exhibited higher activity in the lateral orbitofrontal and dorsolateral prefrontal cortices compared with healthy men and female patients. Positive connectivity between amygdala and posterior middle cingulate cortex was found in female patients but negative connectivity was found in male patients with BPD. Negative modulatory effects of trait anger on amygdala-dorsolateral prefrontal cortex and amygdala-lateral orbitofrontal cortex coupling were shown in male BPD patients, while in female patients trait anger positively modulated dorsolateral prefrontal cortex-amygdala coupling. Trait aggression was found to positively modulate connectivity of the left amygdala to the posterior thalamus in male but not female patients.

CONCLUSIONS

Data suggest poor top-down adjustment of behavior in male patients with BPD despite their efforts at control. Female patients appear to be less aroused through rejection and to successfully dampen aggressive tension during the imagination of aggressive behavior.

Oxytocin and Borderline Personality Disorder

Borderline personality disorder (BPD) is a prevalent and severe mental disorder with affect dysregulation, impulsivity, and interpersonal dysfunction as its core features. Up to now, six studies have been performed to investigate the role of oxytocin in the pathogenesis of BPD. While a beneficial effect of oxytocin on threat processing and stress responsiveness was found, other studies using an oxytocin challenge design presented with rather heterogeneous results. Future studies have to include a sufficiently large sample of patients, control for gender, and focus on mechanisms known to be related to aversive early life experiences.

Biting the hand that feeds: current opinion on the interpersonal causes, correlates, and consequences of borderline personality disorder

Borderline personality disorder (BPD) is a complex psychiatric diagnosis characterized by dysregulated behaviors, emotions, cognitions, and interpersonal relationships. In recent years, developmental psychopathologists have sought to identify early origins of BPD, with the ultimate goal of developing and providing effective preventative interventions for those at highest risk. In addition to heritable biological sensitivities, many scholars assert that environmental and interpersonal risk factors contribute to the emergence and maintenance of key borderline traits. Nonetheless, many BPD researchers examine only affected individuals, neglecting the family, peer, couple, and other dynamic contextual forces that impinge upon individual-level behavior. In the past decade, however, theoretical and empirical research has increasingly explored the interpersonal causes, correlates, and consequences of BPD. Such work has resulted in novel research and clinical theories intended to better understand and improve interpersonal dynamics among those with borderline traits. A major objective for the field is to better characterize how interpersonal dynamics affect (and are affected by) the behaviors, emotions, and thoughts of vulnerable individuals to either reduce or heighten risk for BPD.
