Anxious adult attachment may mediate the relationship between childhood emotional abuse and borderline personality disorder

A cluster analysis of attachment styles in patients with borderline personality disorder, bipolar disorder and ADHD

BACKGROUND

Insecure adult attachment has been associated with psychiatric disorders characterized by emotional dysregulation, such as borderline personality disorder (BPD), bipolar disorder (BD) and attention deficit/hyperactivity disorder (ADHD). However, little is known about the differences in attachment patterns between these diagnostic groups. The aim of this study was to identify clusters of adult attachment style in a cross-diagnostic group of patients with BDP and/or BD and/or ADHD and explore the characteristics of these clusters based on temperament profile, childhood trauma and psychiatric diagnoses.

METHODS

K-means cluster analysis was used to identify subgroups, based on the Attachment Style Questionnaire Short Form dimensions, in a clinical cohort of 150 young adults (113 women and 37 men, mean age ± SD = 23.3 ± 2.1) diagnosed with BPD, and/or BD, and/or ADHD.

RESULTS

Three distinct clusters were identified: a secure, an insecure/avoidant-anxious and an insecure/avoidant cluster. These three clusters differed in temperament profile and related psychiatric diagnoses.

CONCLUSIONS

The three clusters of attachment in individuals with BPD, BD and/or ADHD could support differentiation between the disorders as well provide information usable for planning of treatment.

Differentiating between intrapsychic symptoms and behavioral expressions of borderline personality disorder in relation to childhood emotional maltreatment and emotion dysregulation: an exploratory investigation

BACKGROUND

Borderline personality disorder (BPD) is a severe mental disorder, characterized by pronounced instability in emotions, self-image, and interpersonal relationships. Experiences of childhood maltreatment are among the risk factors for BPD. While self-damaging and aggressive acts often occur, not every person with the disorder shows markedly dysregulated behaviour. Internalized symptoms, such as shame, loneliness, and self-disgust tend to be more pervasive and persist after clinical remission.

OBJECTIVE

Here we investigated associations between BPD symptom severity, childhood maltreatment, and emotion regulation difficulties. We further explored if the Borderline Symptom List (BSL) could potentially be used to differentiate between internalized symptoms (intrapsychic strain) and externalized symptoms (dysregulated behaviours) in future research.

METHOD

187 women with at least mild BPD symptoms (65% having a diagnosis of BPD) completed the BSL 23 including its 11-item supplement (BSL-S), the Childhood Trauma Questionnaire (CTQ), and Difficulties in Emotion Regulation Scale (DERS). Participants further underwent a semi-structured clinical interview to assess BPD criteria (International Personality Disorder Examination, IPDE). Multivariate models and regression-based bootstrapping analyses were performed to test direct and indirect effects.

RESULTS

Childhood trauma severity, especially emotional abuse, positively predicted BPD symptom severity. A significant indirect effect through emotion regulation difficulties was found (k2=.56). When exploring associations with BPD criteria (IPDE), the BSL-23 mean significantly correlated with separation anxiety, identity and mood problems, chronic emptiness, suicidal ideation, and dissociation, while the BSL-S correlated with self-harming impulsive behaviour and anger outbursts.

CONCLUSIONS

Findings complement previous research, highlighting the role of childhood maltreatment and emotion regulation difficulties in BPD. While our findings need to be seen as preliminary and interpreted with caution, they suggest that the BSL may be used to differentiate between internalized symptoms and behavioural expressions of BPD in future research. Such a distinction might help to deepen the understanding of this complex heterogenous disorder.

Physical and Emotional Sibling Violence in Childhood and Attachment in Close Relationships in Adulthood

Despite the consequences of physical and emotional sibling violence, which can last into adulthood, research examining this form of family violence is minimal compared to child abuse, interpartner violence, and elder abuse. One area that has received scarce attention is the connection between physical and emotional sibling violence and attachment in close relationships in adulthood. This research study examines the association between physical and emotional sibling violence and adulthood attachment in a sample of 2,458 individuals who completed a survey on the sub-Reddit platform "/r/SampleSize: Where your opinions actually matter!" Participants completed items on demographics, frequency of physical and emotional behaviors experienced with a sibling in childhood, and adult attachment. Results found physical and emotional sibling violence in childhood to be associated with attachment in close relationships in adulthood. Frequency of physical and emotional sibling violence in childhood was also associated with comfortability with intimacy and closeness, comfortability of depending and relying on others, and concerns of abandonment and rejection by others in adulthood. The findings underscore the need to not only include physical and emotional sibling violence in future research on attachment but also to examine the connection between these phenomena in diverse samples (ethnicity, sexual orientation). Also highlighted is the need for practitioners to assess sibling relationships when working with children, families, and adults experiencing attachment issues throughout the life course.

A Systematic Review of the Association Between Early Childhood Trauma and Borderline Personality Disorder

Borderline personality disorder (BPD) is a debilitating clinical disorder associated with adverse impacts on multiple levels. While a high prevalence of childhood trauma has been noted, the ways such trauma impacts the development of BPD symptomatology remain unclear. In this systematic review, the authors examine the literature from 2000 to 2020, focusing on the association between trauma and BPD, and offer a comprehensive synthesis of possible etiological implications related to either one specific or multiple trauma types. In addition, results are analyzed based on commonly tested trauma parameters, including repeated exposure, polytrauma, onset, perpetrators, and gender. The authors also note some limitations in areas of sampling, measurement, causal inference methods, and data analyses. Results of this review point to several parameters of trauma that can be used to inform training for practitioners as well as enhance current interventions.

On the interplay of borderline personality features, childhood trauma severity, attachment types, and social support

BACKGROUND

Adverse childhood experiences (ACE) have consistently been associated with borderline personality disorder (BPD). Still, it is not yet entirely understood if and how different types of ACE (emotional, physical, sexual abuse, neglect) relate to different BPD subdomains (affective instability, identity disturbance, negative relationships, self-harm). Insecure attachment and lower perceived social support are associated with both ACE and BPD and may therefore contribute to their relationship. No study so far integrated all these variables in one model, while accounting for their mutual influence on each other. We investigated the interplay of BPD subdomains, ACE, attachment, and perceived social support using a graph-theoretical approach.

METHODS

An international sample of 1692 participants completed the Childhood Trauma Questionnaire (CTQ), the Borderline Feature Scale from the Personality Assessment Inventory (PAI-BOR), the Adult Attachment Scale (AAS), and Multidimensional Scale of Perceived Social Support (MSPSS) via an online survey. We estimated a partial correlation network including subscales of the CTQ and the PAI-BOR as nodes. We extended the network by including subscales of the AAS and MSPSS as additional nodes.

RESULTS

Emotional abuse was the most central node in both networks and a bridge between other types of ACE and BPD features. All domains of BPD except affective instability were associated with emotional abuse. Identity disturbances was the most central node in the BPD network. The association between ACE and BPD features was partly but not fully explained by attachment and social support.

CONCLUSION

Our findings suggest that emotional abuse is an important link in the association between ACE and BPD features, also when taking attachment and social support into account. Findings further suggest an outstanding role of identity disturbance, linking emotional abuse to affective instability and being strongly associated with attachment anxiety.

The Effects of Childhood Emotional and Physical Maltreatment on Adolescents' Disordered Eating Behaviors: The Mediating Role of Borderline Personality Features

Over time, a complex crossroad between disordered eating behaviors (DEBs) and borderline personality features (BPFs) and their association with childhood emotional and physical maltreatment have been established. The present study aimed at evaluating the direct and indirect effect of physical and emotional abuse and neglect on DEB via BPF in a nonclinical adolescent sample. A total of 786 adolescents (48.3% male; mean age, 16.25 years; SD, 1.76) participated in the study. The mediation model suggested the pivotal predictive role of emotional maltreatment compared with the physical one. Indeed, both emotional abuse and neglect directly and indirectly predicted disordered eating via BPF ( β = 0.097; p < 0.001 and β = 0.042; p < 0.01, respectively). Likely, the emotional maltreatment represents the beginning of a developmental cascade that culminates in DEB as a maladaptive coping strategy in response to negative emotions, through BPF. On the contrary, physical maltreatment seems to be less involved in the developmental cascade.

Adverse Childhood Experiences and Neurocognition in Borderline Personality Disorder: A Call-to-Action Perspective Review

Adverse childhood experiences (ACEs) contribute to the development of personality traits leading to adult borderline personality disorder (BPD). Neurocognitive changes could partly mediate the association between ACEs and BPD. We discuss how exposure to ACEs could induce alterations in neurocognition, which, in turn, would contribute to the development of BPD. We conducted a review of MEDLINE articles through 2021, documenting a link between ACEs, neurocognitive impairments, and BPD, and also focusing on the pairwise associations. ACEs appear to have a strong impact on neurocognition and are a predictive factor for BPD. Maltreated, abused, and emotionally invalidated children are more likely to present BPD traits. Neurocognitive impairments in adults exposed to ACEs and in patients with BPD arise from similar brain alterations in the amygdala, hippocampus, and prefrontal cortex. These impairments seem to be linked with clinical dimensions of BPD: increased impulsivity to altered inhibitory control; dissociative experiences to nonspecific autobiographical memory; and emotionally biased facial recognition to unstable interpersonal relationships. This perspective review highlights the contributory role of neurocognition in the association between ACEs and BPD. Additional research is needed, however, on the interconnections among ACEs, neurocognition, and BPD. Future studies could also focus on developing tools to assess early adversity in BPD specifically and on psychotherapeutic approaches to promptly remedy neurocognitive impairments.

Developmental Trauma Disorder: A Legacy of Attachment Trauma in Victimized Children

Developmental trauma disorder (DTD) and posttraumatic stress disorder (PTSD) have been found to have both shared and unique traumatic antecedents. The present study was an independent replication, with the DTD Structured Interview and the Traumatic Events Screening Instrument administered to 271 children in mental health treatment in six U.S. sites. On an unadjusted basis, DTD (27.3% prevalence, N = 74) and PTSD (40.2% prevalence, N = 109) both were associated with traumatic physical assault or abuse, family violence, emotional abuse, caregiver separation or impairment, and polyvictimization. After controlling for PTSD, DTD was associated emotional abuse, OR = 2.9, 95% CI [1.19, 6.95], and traumatic separation from a primary caregiver, OR = 2.2, 95% CI [1.04. 4.60], both of which also were associated with caregiver impairment, physical assault/abuse, and witnessing family/community violence. Three traumatic antecedents associated with PTSD were not associated with DTD: noninterpersonal trauma, sexual trauma, and traumatic loss. Children exposed to both traumatic victimization and attachment trauma (36.2%) or attachment trauma alone (32.5%) were more likely than children exposed only to victimization (17.5%) or those with no history of victimization or attachment trauma (8.1%) to meet the symptom criteria for DTD, χ²(3, N = 271) = 17.68, p < .001. Study findings replicate and extend prior DTD field trial study results, showing that, although PTSD and DTD share traumatic antecedents, DTD is uniquely associated with traumatic emotional abuse and caregiver separation. Further research is needed to examine how specific trauma types contribute to the risk, course, and severity of DTD.

The Association Between Childhood Trauma and Attachment Functioning in Patients With Personality Disorders

Attachment (mal)functioning and a history of childhood trauma (CT) are both considered psychological determinants of personality disorders (PDs). Their interaction, however, remains largely uninvestigated. In this study, the authors assessed adult and childhood attachment style in a sample of patients with diverse PDs (N = 75) and determined the relation with both occurrence and severity of CT. The authors found that the sample was characterized by severe attachment malfunctioning and high levels of CT. Using cross-tabulations and analysis of variance, the authors showed that patients with a fearful or dismissive attachment style experienced more severe CT than patients with a preoccupied attachment style. Patients reporting an affectionless control bonding style to either parent suffered frequent and severe CT. Although temporal causality cannot be determined, these findings stress the necessity to screen for CT in PDs and suggest that attachment-centered psychotherapy for these patients may benefit from preceding or concurrent trauma treatment.

Attachment anxiety as mediator of the relationship between childhood trauma and personality dysfunction in borderline personality disorder

Insecure attachment has been described as mediating the relationship between childhood trauma and dysfunctional personality traits in different mental disorders. Despite the role insecure attachment and childhood trauma have independently demonstrated to play as determinants of borderline personality disorder, less is known about the mediating mechanisms explaining these associations. For the first time, we assessed adult attachment, childhood trauma and dimensional personality pathology in a sample of outpatients with borderline personality disorder and tested whether the association between childhood trauma and personality dysfunction was at least partially attributable to insecure attachment. The results showed that attachment anxiety fully mediated the relationship between specific types of trauma (emotional abuse and physical neglect) and emotional dysregulation. Further, emotional abuse was both directly associated with dissocial behaviour and indirectly via attachment anxiety (partial mediation). Emotional abuse has been described as an essential environmental factor for the development of borderline personality disorder and emotional dysregulation, on its part, as the core feature of the condition. Our results indicate that attachment anxiety explains the link between these central aspects of borderline personality disorder. Our findings are consistent with previous research and current etiological understanding of the condition and provide support for recommending a careful assessment of childhood traumatic experiences and adult attachment style to gain a more comprehensive insight into the symptoms and its heterogeneity. As a secondary aim, we assessed the effect parental mental illness may have in these mediation models, but no significant influence on childhood trauma, attachment or personality was found.

Insecure attachment and maladaptive emotion regulation mediating the relationship between childhood trauma and borderline personality features

BACKGROUND

Previous studies suggested that childhood trauma is an important etiologic factor for the development of borderline personality disorder (BPD). Moreover, insecure attachment and maladaptive emotion regulation (ER) might be related to childhood trauma and BPD. This study was aimed to explore the relationships among childhood trauma, insecure attachment, maladaptive ER, and BPD features.

METHODS

A cohort of 637 patients with psychological disorders completed a series of psychometric instruments such as the Personality Diagnostic Questionnaire-4+ (PDQ-4+), the 23-Item Borderline Symptom List, the Childhood Trauma Questionnaire, the Attachment Style Questionnaire, and the Cognitive Emotion Regulation Questionnaire. The path analyses were conducted to investigate the experience-driven model that whether insecure attachment and maladaptive ER could mediate the relationship between childhood trauma and BPD features. The random forest regression was performed to select variables that contribute significantly to BPD features, which variables would be incorporated into the data-driven model to further confirm the experience-driven model.

RESULTS

Both the experience-driven model and the data-driven model verified that there were three significant mediation pathways (childhood trauma → insecure attachment/maladaptive ER → BPD features, childhood trauma → insecure attachment → maladaptive ER → BPD features; all p < .05), and the most weighted mediation pathway by which childhood trauma influencing the BPD features was through insecure attachment and then through maladaptive ER (weighted 53.16%).

CONCLUSION

The influence of childhood trauma on BPD features was mainly mediated by the combination of insecure attachment and maladaptive emotion regulation.

Childhood adversity and borderline personality disorder: a meta-analysis

OBJECTIVE

The aim of this meta-analysis was to better understand the magnitude and consistency of the association between childhood adversity and borderline personality disorder (BPD) across case-control, epidemiological and prospective cohort studies.

METHOD

Following the review protocol (reference: CRD42017075179), search terms pertaining to adversity and BPD were entered into three search engines. Random-effects meta-analysis synthesised the size and consistency of the effects.

RESULTS

A total of 97 studies compared BPD to non-clinical (k = 40) and clinical (k = 70) controls. Meta-analysis of case-control studies indicated that individuals with BPD are 13.91 (95% CI 11.11-17.43) times more likely to report childhood adversity than non-clinical controls. This effect was smaller when considering retrospective cohort (OR: 2.59; 95% CI 0.93-7.30) and epidemiological (OR: 2.56, 95% CI 1.24-5.30) studies. Findings were significant across adversity subtypes with emotional abuse (OR: 38.11, 95% CI: 25.99-55.88) and neglect (OR: 17.73, 95% CI = 13.01-24.17) demonstrating the largest effects. Individuals with BPD were 3.15 (95% CI 2.62-3.79) times more likely to report childhood adversity than other psychiatric groups.

CONCLUSIONS

This meta-analysis corroborates theoretical proposals that exposure to adverse life experiences is associated with BPD. It highlights the importance of considering childhood adversity when treating people diagnosed with BPD.

Attachment and Borderline Personality Disorder

Borderline personality disorder is associated with predominant insecure and unresolved attachment representations, linked history of trauma, impaired cognitive functioning and oxytocin levels, and higher limbic activations. Two randomized clinical trials on transference-focused psychotherapy assessed change of attachment representation and reflective functioning. The first showed that transference-focused psychotherapy was superior, demonstrating significant improvements toward attachment security and higher reflective functioning. The second randomized clinical trial study on transference-focused psychotherapy compared with therapy as usual replicated these results and additionally showed a significant shift from unresolved to organized attachment in the transference-focused psychotherapy group only, suggesting its effectiveness in traumatized patients.

Borderline personality disorder and sexual abuse: A systematic review

Although sexual abuse (SA) is known to be frequent among borderline personality disorder (BPD) patients, few reviews evaluating that relationship have been published. This systematic review aimed to investigate SA (including adulthood) as a predictor of BPD diagnosis, clinical presentation and prognosis. Studies written in English or Portuguese from January 1997 until January 2017 were identified by searching the following keywords in three international databases: "borderline personality disorder" OR "borderline disorder" AND "sexual abuse" OR "sexual violence" OR "sexual victimization" OR "sexual assault" OR "rape". Forty articles met the eligibility criteria. Overall, SA was found to play a major role in BPD, particularly in women. Childhood sexual abuse (CSA) is an important risk factor for BPD. Adult sexual abuse (ASA) rates are significantly higher in BPD patients compared with other personality disorders (PDs). SA history predicts more severe clinical presentation and poorer prognosis. Suicidality has the strongest evidence, followed by self-mutilation, post-traumatic stress disorder (PTSD), dissociation and chronicity of BPD. Future research should study more ASA and include more males, milder BPD patients and documented or corroborated SA cases. The impact of other traumatic experiences (e.g., emotional abuse) on BPD must also be systematically reviewed.

Reduced white matter integrity in borderline personality disorder: A diffusion tensor imaging study

BACKGROUND

Borderline personality disorder (BPD) has a pervasive pattern of instability in interpersonal relationships, self-image, and emotions. BPD may be linked to an abnormal brain anatomy, but little is known about possible impairments of the white matter microstructure in BPD or their relationship with impulsivity or risky behaviors. The aims of the present study were to explore the relationship between BPD and diffusion tensor imaging (DTI) parameters and psychological tests.

METHODS

We evaluated 35 un-medicated BPD patients in a medication-free state and 50 healthy controls (HCs). We performed DTI tractography in BPD patients and HCs. The Childhood Trauma Questionnaire (CTQ), Profile of Mood State (POMS), State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), Social Adaptation Self-Evaluation Scale (SASS), and Depression and Anxiety Cognition Scale (DACS) were administered to BPD patients and HCs.

RESULTS

A tract-based spatial statistics (TBSS) revealed that the BPD group had three clusters with a significantly lower axial diffusivity (AD) than the HC group: one located mainly in the cingulum and the other mainly in the inferior front-occipital fasciculus and inferior longitudinal fasciculus. Regarding the AD values, one cluster correlated negatively and significantly with POMS (Depression) and it was located in the cingulum, while another cluster correlated positively and significantly with DACS (Future Denial) and it was located in the inferior front-occipital fasciculus (IFOF).

LIMITATIONS

The small sample size of this study prevents us from forming any definitive conclusions, meaning that more studies are needed to confirm our findings. We are unable to generalize our findings to include other ethnic groups.

CONCLUSIONS

Our results suggested that hypo-metabolism in a front-limbic network dysfunction is characterized by the cingulum and a front-occipital network dysfunction characterized by the occipital lobe, while an occipital-temporal network dysfunction characterized by the inferior longitudinal fasciculus.

How Do Stress Exposure and Stress Regulation Relate to Borderline Personality Disorder?

Borderline personality disorder (BPD) is a severe and frequent disorder characterized by a pervasive pattern of instability affecting impulse control, emotional regulation, cognitive processing, self-image and interpersonal relationships. Patients’ personal histories are often marked by stressful or traumatic experiences, either unique or repeated. Moreover, while clinical signs of the disorder include both chronic and acute features, acute features are mostly triggered by acute stressful situations. Such features include transient cognitive distortion, intense anger, uncontrollable impulsivity, and self-harm behavior – including suicide – and contribute to the burden of the disease. In this paper, we review the various aspects (epidemiological, clinical, and physiological) contributing to the relationship between BDP and stress. In particular, we explore the statistical association between stress exposure and the emergence of BPD while taking into account other psychopathologies, such as post-traumatic stress disorder. Then, the different aspects of stress responses (namely, the phenomenological, behavioral, hormonal, neuro-vegetative and neural responses) are reviewed in BPD patients. Pathophysiological hypotheses are formulated to explain the differences in responses between BPD patients and healthy subjects and their relation to BPD symptoms. Although the pathogenesis remains uncertain, our conclusions seem to reflect a specific biological and neural pattern of altered stress perception and regulation in BPD.
