Differential associations between childhood maltreatment types and borderline personality disorder from the perspective of emotion dysregulation

"Vulnerability can breed strength": The role of borderline personality disorder severity in movement synchrony among patients with major depressive disorder

Objective: Patients with Major depressive disorder (MDD) and a comorbid Borderline personality disorder (BPD) show a poorer prognosis for MDD compared to patients without BPD. Little is known about the therapeutic processes underlying this prognosis. The goal of the present study was to investigate whether patients with more severe BPD symptoms experience less strengthening in patient-therapist movement synchrony (MS) throughout treatment, and whether less strengthening in MS is associated with less effective sessions. Method: Ninety-five patients participating in a randomized control trial were assessed for BPD (N = 9) using the Structured Interview for DSM-IV Personality. 1367 video-taped sessions were analyzed for MS using Motion Energy Analysis. Session effectiveness was evaluated following each session using a one-item scale taken from the Helping Skills Measure. Multilevel models were used to assess whether BPD severity predicted MS throughout treatment, and whether MS predicted session effectiveness. Results: Patients with more severe BPD symptoms experienced greater strengthening in MS throughout treatment. Less MS strengthening was associated with less session effectiveness. Conclusion: These findings indicate unique therapeutic processes that characterize individuals with more severe BPD symptoms. Shedding light on these unique processes has the potential to contribute to the personalization of MDD treatment for patients with BPD.

Culture and ICD-11 personality disorder: Implications for clinical practice across diverse ethnic groups

BACKGROUND

Personality disorder (PD) in ICD-11 is defined primarily by self and interpersonal dysfunction and optionally by other qualifiers. This definition is inseparable from relativism of cultural determinants.

AIMS

This review aimed to synthesize the relevant aspects of the influence of culture on clinical practice and health management for this condition, aligning them to the ICD-11 PD model.

METHOD

In Scopus, we systematically searched for studies that included the text strings: cultur* | personality AND (disorder* OR patholog*) without any restrictions on publication date or language or other exclusion criteria, up to November 2022.

RESULTS

Evidence suggests that cultural variables in ethnic groups (Western and non-Western) such as the individualist/collectivist philosophy, historical/generational trauma, immigration, acculturation, religion, and gender influence the etiology, semiology, epidemiology, evaluation, diagnosis, treatment, and management of health services for ICD-11 PD. We discuss the limitations and propose future lines of research on this topic based on our knowledge and experience. In this review, we provide the scientific community and clinicians with relevant cultural information to guide their practice and propose strategies to manage PD from the ICD-11 model.

CONCLUSIONS

More research is needed using mixed study methodologies on stigma, the experiences of patients, clinicians, and health agencies, to reduce the care gaps and achieve a culturally comprehensive, inclusive, and competent use of this new model.

Borderline personality features in relationship to childhood trauma in unipolar depressive and bipolar disorders

BACKGROUND

Childhood trauma, including emotional neglect, emotional abuse, physical abuse, and sexual abuse, may contribute to borderline personality features like affective instability, identity problems, negative relationships, and self-harm. This study aims to explore how different types of childhood trauma affect these features in bipolar versus unipolar depressive disorders.

METHODS

We included 839 participants of the Netherlands Study of Depression and Anxiety (NESDA) with a lifetime diagnosis of major depressive disorder single episode (MDDS; N = 443), recurrent major depressive disorder (MDD-R; N = 331), or bipolar disorder (BD; N = 65). Multivariate regression was used to analyze data from the Childhood Trauma Interview and borderline features (from the self-report Personality Assessment Inventory).

RESULTS

On average, participants were 48.6 years old (SD: 12.6), with 69.2 % being women, and 50.3 % of participants assessed positive for childhood trauma. Adjusted analyses revealed that participants diagnosed with BD, followed by MDD-R, exhibited the highest number of borderline personality features. Additionally, within the entire group, a strong association was found between childhood trauma, especially emotional neglect, and the presence of borderline personality features.

CONCLUSION

Given the high prevalence of childhood trauma and borderline personality features, screening for these factors in individuals with mood disorders is crucial. Identifying these elements can inform and enhance the management of the often fluctuating and complex nature of these comorbid conditions, leading to more effective and tailored treatment strategies.

Childhood adversity modulates structural brain changes in borderline personality but not in major depression disorder

Adverse childhood experiences (ACEs) negatively affect the function and structure of emotion brain circuits, increasing the risk of various psychiatric disorders. It is unclear if ACEs show disorder specificity with respect to their effects on brain structure. We aimed to investigate whether the structural brain effects of ACEs differ between patients with major depression (MDD) and borderline personality disorder (BPD). These disorders share many symptoms but likely have different etiologies. To achieve our goal, we obtained structural 3T-MRI images from 20 healthy controls (HC), 19 MDD patients, and 18 BPD patients, and measured cortical thickness and subcortical gray matter volumes. We utilized the Adverse Childhood Experiences (ACE) questionnaire to quantify self-reported exposure to childhood trauma. Our findings suggest that individuals with MDD exhibit a smaller cortical thickness when compared to those with BPD. However, ACEs showed a significantly affected relationship with cortical thickness in BPD but not in MDD. ACEs were found to be associated with thinning in cortical regions involved in emotional behavior in BPD, whereas HC showed an opposite association. Our results suggest a potential mechanism of ACE effects on psychopathology involving changes in brain structure. These findings highlight the importance of early detection and intervention strategies.

Components of event-related potentials and borderline personality disorder: a meta-analysis

Background: Borderline personality disorder (BPD) is characterized by symptoms associated with difficulties in emotion regulation, altered self-image, impulsivity, and instability in personal relationships. A relationship has been found between BPD symptoms and altered neuropsychological processes. Studies of event-related potentials (ERP) measured with electroencephalogram (EEG) have found neural correlates related to BPD symptoms. Of note is the P300 component, considered a potential mental health biomarker for trauma-associated disorders. However, no meta-analysis has been found to demonstrate this relationship.Objectives: To evaluate the relationship between the P300 component and BPD symptoms. To evaluate the relationship of other ERP components with BPD symptoms.Methods: The method and procedure were adjusted to the PRISMA checklist. The search was performed in three databases: WOS, Scopus and PubMed. A Random Effects Model was used to perform the analysis of the studies. In addition, a meta-regression was performed with % women, Gini and GDP. Finally, a descriptive analysis of the main results found between P300, other ERP components (LPP, P100 and ERN/Ne) and BPD symptoms was performed.Results: From a review of 485 articles, a meta-analysis was performed with six articles that met the inclusion criteria. A moderate, positive relationship was found between the P300 component and BPD symptoms (REM = .489; p < .001). It was not possible to perform meta-analyses for other ERP components (LPP, P100 and ERN/Ne) due to the low number of articles found.Conclusion: The idea that P300 could be considered for use as a biomarker to identify altered neural correlates in BPD is reinforced. In addition, a moderating effect of inequality (Gini) was detected.

Childhood psychological maltreatment and adolescent depressive symptoms: Exploring the role of social anxiety and maladaptive emotion regulation strategies

BACKGROUND

Despite emerging evidence for the effect of childhood psychological maltreatment on adolescent depressive symptoms, the underlying processes for this effect are largely under-investigated. This study examined a conceptual framework for the effect of childhood psychological maltreatment on adolescent depressive symptoms through social anxiety disorder (SAD) and maladaptive emotion regulation strategies.

METHODS

The participants were 1649 Chinese middle school students (751 girls and 898 boys) with a mean age of 16.29 ± 1.04 years old. A moderation-mediation model hypothesized that childhood psychological maltreatment predicts adolescent depressive symptoms, with SAD as a mediator and maladaptive emotion regulation strategies as a moderator.

RESULTS

Childhood psychological maltreatment significantly positively predicted adolescent depressive symptoms, while SAD mediated the relation. Maladaptive emotion regulation strategies moderated the pathways from psychological maltreatment to depressive symptoms (but not from psychological maltreatment to SAD) and from SAD to adolescent depressive symptoms.

LIMITATIONS

Subjective measures, and the cross-sectional design are the main limitations.

CONCLUSIONS

SAD plays a mediating role in the relation between childhood psychological maltreatment and depressive symptoms. Maladaptive emotion regulation strategies exacerbate the relation between childhood psychological maltreatment and depressive symptoms, as well as the relation between SAD and depressive symptoms. These results highlight the importance of addressing social anxiety in reducing adolescent depressive symptoms by improving their cognitive emotion regulation strategies.
