Resting-State EEG Microstates and Power Spectrum in Borderline Personality Disorder: A High-Density EEG Study

Borderline personality disorder (BPD) is a debilitating psychiatric condition characterized by emotional dysregulation, unstable sense of self, and impulsive, potentially self-harming behavior. In order to provide new neurophysiological insights on BPD, we complemented resting-state EEG frequency spectrum analysis with EEG microstates (MS) analysis to capture the spatiotemporal dynamics of large-scale neural networks. High-density EEG was recorded at rest in 16 BPD patients and 16 age-matched neurotypical controls. The relative power spectrum and broadband MS spatiotemporal parameters were compared between groups and their inter-correlations were examined. Compared to controls, BPD patients showed similar global spectral power, but exploratory univariate analyses on single channels indicated reduced relative alpha power and enhanced relative delta power at parietal electrodes. In terms of EEG MS, BPD patients displayed similar MS topographies as controls, indicating comparable neural generators. However, the MS temporal dynamics were significantly altered in BPD patients, who demonstrated opposite prevalence of MS C (lower than controls) and MS E (higher than controls). Interestingly, MS C prevalence correlated positively with global alpha power and negatively with global delta power, while MS E did not correlate with any measures of spectral power. Taken together, these observations suggest that BPD patients exhibit a state of cortical hyperactivation, represented by decreased posterior alpha power, together with an elevated presence of MS E, consistent with symptoms of elevated arousal and/or vigilance. This is the first study to investigate resting-state MS patterns in BPD, with findings of elevated MS E and the suggestion of reduced posterior alpha power indicating a disorder-specific neurophysiological signature previously unreported in a psychiatric population.

The (cost-)effectiveness of early intervention (MBT-early) versus standard protocolized treatment (CBT) for emerging borderline personality disorder in adolescents (the EARLY study): a study protocol for a randomized controlled trial

BACKGROUND

Although clinical guidelines prioritize the treatment of depression and anxiety in young persons, there is accumulating evidence that the presence of symptoms of borderline personality disorder (BPD) is associated with the limited effectiveness of these standard treatments. These findings stress the need for interventions addressing early-stage BPD in young people with presenting symptoms of anxiety and depressive disorders. The aim of this study is to investigate the (cost-)effectiveness of an early intervention programme for BPD (MBT-early) compared to first-choice psychological treatment for depression and anxiety according to Dutch treatment guidelines (CBT), in adolescents with either depression, anxiety, or both, in combination with early-stage BPD.

METHODS

This study is a multi-centre randomized controlled trial. A total of 132 adolescents, presenting with either depression, anxiety, or both and significant BPD features will be randomized to either MBT-early or CBT. The severity of BPD, symptoms of depression and anxiety, personality, social and academic functioning, and quality of life will be assessed at baseline, end of treatment, and at 12-, 18-, and 24-month follow-up, along with medical costs and costs of productivity losses for cost-effectiveness analyses.

DISCUSSION

This study will provide an empirical evaluation of the potential surplus value of early intervention in young people for whom treatment oriented at common mental disorders like anxiety and depression may be insufficient given their underlying personality problems.

Comparison of ACE-IQ and CTQ-SF for child maltreatment assessment: Reliability, prevalence, and risk prediction

BACKGROUND

Child maltreatment has profound effects on mental health. The Childhood Trauma Questionnaire Short Form (CTQ-SF) and the Adverse Childhood Experiences International Questionnaire (ACE-IQ) are commonly used retrospective assessment tools for evaluating child maltreatment.

OBJECTIVE

This study aims to conduct a comprehensive comparison of the CTQ-SF and ACE-IQ, encompassing internal consistency, prevalence, and the predictive efficacy of trauma-related outcomes. It also seeks to enhance the scoring method of ACE-IQ based on the established comparability between the two instruments.

PARTICIPANTS AND SETTING

1484 college students from northern China were recruited, assessing demographic characteristics and outcomes related to traumatic experiences, including post-traumatic stress disorder (PTSD), complex post-traumatic stress disorder (CPTSD), borderline personality disorder (BPD), anxiety, and depression.

METHODS

A contingency correlation analysis was performed to evaluate the degree of agreement between the CTQ-SF and ACE-IQ. Binary logistic regression models were utilized to compare the predictive capabilities of distinct instruments.

RESULTS

CTQ-SF and ACE-IQ instruments display favorable internal consistency and notable correlations across shared categories. However, the predictive relationships between trauma type and adverse outcomes are inconsistent across instruments. The ACE-IQ, encompassing 13 trauma categories, demonstrate a lower AIC and BIC index, indicating a superior model fit for elucidating outcomes.

CONCLUSION

This study introduces a scoring methodology for ACE-IQ, improving the comparability of the two measures and emphasizing the importance of capturing the full range of maltreatment types a child may have experienced. These findings have significant implications for clinical and epidemiological research, providing valuable insights for understanding the impact of child maltreatment.

Psychometric properties of the Hungarian childhood trauma questionnaire short form and its validity in patients with adult attention-deficit hyperactivity disorder or borderline personality disorder

BACKGROUND

Compelling evidence supports the role of childhood traumatization in the etiology of psychiatric disorders, including adult attention-deficit hyperactivity disorder (aADHD) and borderline personality disorder (BPD). The aim of this study was to examine the psychometric properties of the Hungarian version of the Childhood Trauma Questionnaire Short Form (H-CTQ-SF) and to investigate the differences between patients diagnosed with aADHD and BPD in terms of early traumatization.

METHODS

Altogether 765 (mean age = 32.8 years, 67.7% women) patients and control subjects were enrolled from different areas of Hungary. Principal component analysis and confirmatory factor analysis were carried out to explore the factor structure of H-CTQ-SF and test the validity of the five-factor structure. Discriminative validity was assessed by comparing clinical and non-clinical samples. Subsequently, aADHD and BPD subgroups were compared with healthy controls to test for the role of early trauma in aADHD without comorbid BPD. Convergent validity was explored by measuring correlations with subscales of the Personality Inventory for DSM-5 (PID-5).

RESULTS

The five scales of the H-CTQ-SF demonstrated adequate internal consistency and reliability values. The five-factor model fitted the Hungarian version well after exclusion of one item from the physical neglect scale because of its cross-loading onto the emotional neglect subscale. The H-CTQ-SF effectively differentiated between the clinical and non-clinical samples. The BPD, but not the aADHD group showed significant differences in each CTQ domain compared with the healthy control group. All CTQ domains, except for physical abuse, demonstrated medium to high correlations with PID-5 emotional lability, anxiousness, separation insecurity, withdrawal, intimacy avoidance, anhedonia, depressivity, suspiciousness, and hostility subscales.

CONCLUSIONS

Our study confirmed the psychometric properties of the H-CTQ-SF, an easy-to-administer, non-invasive, ethically sound questionnaire. In aADHD patients without comorbid BPD, low levels of traumatization in every CTQ domain were comparable to those of healthy control individuals. Thus, the increased level of traumatization found in previous studies of aADHD might be associated with the presence of comorbid BPD. Our findings also support the role of emotional neglect, emotional abuse and sexual abuse in the development of BPD.

Life experienced as worth living and beyond: a qualitative study of the pathways to recovery and flourishing amongst individuals treated for borderline personality disorder

BACKGROUND

Dialectical Behaviour Therapy (DBT) is recognized as a leading evidence-based treatment, effective in reducing symptoms of borderline personality disorder (BPD), as well as co-occurring clinical syndromes. However, symptom remission may not be the same as a life experienced as worth living. The purpose of the study was to understand, from the perspective of individuals with lived experience, the concepts of recovery, life experienced as worth living and flourishing after treatment for BPD, and to describe the pathways to wellness after symptom remission.

METHODS

Semi-structured interviews were conducted with nine adult women previously diagnosed with BPD, co-occurring clinical syndromes and severe self-harm behaviour who self-identified as recovered for a minimum of two years, recruited from a network for individuals with lived experience. The average duration of recovery was 5.7 years with a range from 2 to 10 + years. Data were analysed using thematic analysis.

RESULTS

Four main themes and 14 subthemes were generated from our analyses. Main themes indicated that loved ones helped recovery and to create a life worth living, that participants identified as recovered and as healthy and beyond, and that becoming well is a long process associated in part with reclaiming a healthy identity. Participants defined recovery as separate but related to a life worth living, which in turn was separate but related to being healthy and having lives they described as being beyond health and well-being. The wellness process was described as lengthy and non-linear, including setbacks that with time no longer derailed daily life. A proposed theoretical model depicting the wellness process over time from symptom remission to the experience of a life beyond health and wellness is presented.

CONCLUSIONS

This qualitative study contributes knowledge of what a life experienced as worth living means, as well as how wellness progressed into flourishing for some participants within a sample of individuals with lived experience. Our findings may inform treatment development that targets more than symptom reduction, which in turn may shorten trajectories from symptom remission to health, wellness, and flourishing.

Sub-threshold or full-syndrome borderline personality disorder in adolescents with recurrent self-harm - distinctly or dimensionally different?

BACKGROUND

Borderline personality disorder (BPD) is a severe mental disorder frequently seen in individuals with recurrent self-harm behaviour. To what extent there are distinguishing characteristics between self-harming adolescents who meet the criteria for a full diagnosis of BPD, a sub-threshold number of BPD criteria and those who don't have BPD, with respect to clinical characteristics, is still uncertain and could have important clinical implications.

METHODS

Data from 103 adolescents with recurrent self-harm behaviour recruited from child and adolescent psychiatric outpatient clinics were collected through clinical interviews and self-reports. Bivariate analyses comparing participants with or without a diagnosis of BPD were performed. Group differences based on the number of BPD criteria fulfilled (few-if-any BPD: 0-2 criteria, sub-threshold BPD: 3-4 criteria, full-syndrome BPD: 5 or more criteria) were tested and regression analyses performed.

RESULTS

Adolescents with a diagnosis of BPD (28.2%) had significantly higher numbers of co-morbid DSM-5 disorders, suicide attempts and self-harm methods. They also reported significantly higher levels of suicidal ideation, depression, anxiety and impulsivity, compared with adolescents without BPD. Adolescents with sub-threshold BPD (20.4%) place themselves in the intermediate position between participants with full-syndrome BPD and participants with few-if-any BPD, in terms of these symptoms. Higher levels of emotional regulation difficulties and a lower level of global functioning were significantly associated with fulfilling a higher number of BPD criteria.

CONCLUSION

Adolescents with recurrent self-harm who meet diagnostic criteria for a full-syndrome BPD or sub-threshold BPD seem to have difficulties within the same spectrum. They seem dimensionally, but not categorically, different with respect to the severity of their difficulties. These adolescents need interventions aimed at their dysfunctional self-harm behaviour, emotional regulation difficulties and BPD symptoms at an earlier, rather than at a later stage of symptom development.

Borderline personality disorder features and their relationship with trauma and dissociation in a sample of community health service users

BACKGROUND

Previous studies have indicated that borderline personality disorder (BPD) is closely associated with trauma and dissociation. Nevertheless, BPD is a heterogeneous condition, and not all people with BPD have severe dissociation. This study examined whether the relationship of BPD features with trauma and dissociation would remain significant after controlling for some general non-specific mental health distress. We also made the first attempt to explore which specific BPD features would be particularly associated with dissociation.

METHODS

We analyzed survey data from a sample of community health service users in Hong Kong (N = 376). Hierarchical multiple regression and data-driven network analysis were used.

RESULTS

The lifetime prevalence of DSM-5 BPD was 16.0% in our sample. Of participants who met criteria for BPD, 43.3% scored above cutoff on the dissociation measures, thus possibly having clinically significant dissociative symptoms. BPD features were associated with adulthood trauma and psychoform dissociation even after controlling for age, depression and self-esteem. Network analysis showed that some BPD features - including impulsivity, identity disturbance and suicidal/self-mutilation behaviors - were particularly associated with dissociation; other BPD features such as interpersonal-related problems had relatively weak to no connection with dissociation.

CONCLUSIONS

Our results suggested that some particular BPD features might be dissociative in nature, although further longitudinal research is required. We argue that a trauma-informed perspective should be employed when working with clients presenting with BPD features despite these features being commonly stigmatized. Further research on the intervention needs of the people with BPD who suffer from high levels of dissociation is required.

Emotion regulation and borderline personality features in daily life: The role of social context

BACKGROUND

Borderline personality disorder (BPD) is associated with emotional dysfunction and interpersonal sensitivity. Yet, little work has characterized how BPD features predicts emotional reactivity and emotion regulation behaviors in response to interpersonal stress relative to other forms of stress.

METHODS

Participants were 152 university students who completed baseline measures of BPD features and complied with two-week daily diary procedures assessing daily emotion regulation strategy use in response to social and non-social stressors.

RESULTS

Generalized estimating equations revealed that BPD features predicted greater negative and positive emotions in response to daily stressors, and interacted with type of stressor in predicting urges and behaviors. Elevated BPD features was associated with greater urges for dysfunctional emotion regulatory behaviors and fewer functional emotion regulatory behaviors to a greater extent in response to social (versus non-social) stressors.

LIMITATIONS

This study was limited by its focus on past-day retrospective recall. Further, the student sample limits the generalizability of these findings.

CONCLUSIONS

These findings suggest that individuals with elevated BPD features may have less functional emotion regulation in social contexts.

Aberrant functional connectivity profiles of brain regions associated with salience and reward processing in female patients with borderline personality disorder

Recent resting-state functional connectivity studies have shown significant group differences in several networks between patients suffering from borderline personality disorder (BPD) and healthy controls. However, reliable and consistent findings have not been reported yet. Several methodological factors might be responsible for the discrepant findings, including the heterogeneity of patient samples in terms of symptom severity. In the current study, we combined investigations of the whole-brain resting-state functional connectivity patterns of BPD patients with seed-based connectivity measures and then computed the correlation of connectivity measures with borderline symptom severity. Correlation-based connectivity analysis was performed on resting-state functional magnetic resonance imaging (fMRI) data from 26 female BPD patients and 26 healthy controls. Increased intrinsic connectivity was found in clusters involving part of the caudate nucleus and the left insula in the patient group, indicating greater integration of each region. Further seed-based connectivity analyses revealed that with the caudate seed, the patient data exhibited an increased resting-state functional connectivity in the bilateral ventral striatum and the midline prefrontal regions extending to the ACC, a network associated with reward processing. The left insula seed showed significantly increased connectivity with the bilateral fronto-orbital/insula, the inferior parietal lobule and the mid-cingulate cortex, a network involved in attention and salience encoding, in the patient population. Moreover, symptom severity, as assessed with the BSL-95 outside the scanner, was negatively correlated with the coupling of the insula and the striatum in the BPD group. Overall, an increased functional connectivity within two large-scale circuitries underlying reward and salience processing was evident in patients, as compared to healthy participants. When correlated with borderline symptom severity, a reduced connectivity between key regions belonging to the reward system and salience network was observed in the patients. These findings may be helpful for facilitating further understanding of the potential mechanisms underlying the BPD pathophysiology and thereby delineate potential treatment targets.

Targeted bisulfite sequencing: A novel tool for the assessment of DNA methylation with high sensitivity and increased coverage

DNA methylation analysis is increasingly used in stress research. Available methods are expensive, laborious and often limited by either the analysis of short CpG stretches or low assay sensitivity. Here, we present a cost-efficient next generation sequencing-based strategy for the simultaneous investigation of multiple candidate genes in large cohorts. To illustrate the method, we present analysis of four candidate genes commonly assessed in psychoneuroendocrine research: Glucocorticoid receptor (NR3C1), Serotonin transporter (SLC6A4), FKBP Prolyl isomerase 5 (FKBP5), and the Oxytocin receptor (OXTR). DNA methylation standards (100 %; 75 %; 50 %; 25 % and 0 %) and DNA of a female and male donor were bisulfite treated in three independent trials and were used to generate sequencing libraries for 42 CpGs from the NR3C1 1 F promoter region, 84 CpGs of the SLC6A4 5' regulatory region, 5 CpGs located in FKBP5 intron 7, and additional 12 CpGs located in a potential enhancer element in intron 3 of the OXTR. In addition, DNA of 45 patients with borderline personality disorder (BPD) and 45 healthy controls was assayed. Multiplex libraries of all samples were sequenced on a MiSeq system and analyzed for mean methylation values of all CpG sites using amplikyzer2 software. Results indicated excellent accuracy of the assays when investigating replicates generated from the same bisulfite converted DNA, and very high linearity (R² > 0.9) of the assays shown by the analysis of differentially methylated DNA standards. Comparing DNA methylation between BPD and healthy controls revealed no biologically relevant differences. The technical approach as described here facilitates targeted DNA methylation analysis and represents a highly sensitive, cost-efficient and high throughput tool to close the gap between coverage and precision in epigenetic research of stress-associated phenotypes.

Understanding empathy and its disorders through a focus on the neural mechanism

Empathy is a complex, multi-dimensional process. As such, it can be impaired at multiple stages, producing disorders of empathy with separable underlying causes. Studies often divide empathy into emotional and cognitive components to simplify the large space of empathic processes. This practice can be helpful, but also causes people to misunderstand their interdependence at the level of the mechanism and how they correspond to surveys and tasks. As a result, inferences made from experimental results are often incorrect and cannot be integrated across studies. We explain how emotional and cognitive empathy overlap through the proximate mechanism and clarify their operationalization in common surveys and tasks. A systematic review of three clinical disorders is used to highlight this issue and reinterpret and unite results according to the proximate framework--Borderline Personality Disorder (BPD), Narcissistic Personality Disorder (NPD), and Frontotemporal Dementia (FTD). Aligning constructs through the proximate mechanism allows us to understand both empathy and its disorders.

Implicitly measured aggressiveness self-concepts in women with borderline personality disorder as assessed by an Implicit Association Test

BACKGROUND

Aggressiveness resulting from inappropriately intense anger plays a major role in borderline personality disorder (BPD) and research using self-report measures has consistently found elevated levels of aggression in this condition. However, while self-report assesses explicit dimensions of the self-concept, it cannot elucidate implicit processes that are at least equally important as they guide the perceptions of the self and influence behavioral responses. The present study aimed to extend the research on aggressiveness self-concepts in BPD utilizing an indirect latency-based measure.

METHODS

Twenty-nine female inpatients with BPD and 21 healthy women were assessed with an aggressiveness self-concept Implicit Association Test (Agg-IAT) using reaction time measurements to determine the relative strengths of associations between the self vs. others and aggression vs. peacefulness. Additionally, participants completed self-report questionnaires capturing aggressiveness and BPD symptoms.

RESULTS

Women with BPD had a significantly more aggressive self-concept as indicated by the Agg-IAT than the control group. Moreover, they rated themselves significantly more aggressive on all dimensions than the controls. As expected, correlations between the Agg-IAT and the self-reported aggressiveness dimensions were low (mean r = -.31).

LIMITATIONS

The modest sample size and the disregard of a clinical control group limit the generalizability and specificity of our findings.

CONCLUSIONS

This study extends prior findings on aggression in BPD in that women with BPD do not only explicitly conceive themselves as more aggressive, but also exhibit implicitly more aggressive self-concepts than healthy controls. Because implicit and explicit self-related operations are related, but distinct processes, our results may hold clinical and therapeutic implications.

Physical exercise in attention deficit hyperactivity disorder - evidence and implications for the treatment of borderline personality disorder

A growing body of literature indicates a potential role for physical exercise in the treatment of attention deficit hyperactivity disorder (ADHD). Suggested effects include the reduction of ADHD core symptoms as well as improvements in executive functions. In the current review, we provide a short overview on the neurophysiological mechanisms assumed to underlie the beneficial effects of exercise. Further, we review the current evidence from experimental studies regarding both acute exercise and long-term interventions in ADHD. While the positive effects observed after acute aerobic exercise are promising, very few well-designed long-term intervention studies have been conducted yet. Moreover, although exercise effects have not yet been studied in borderline personality disorder (BPD), in the end of this paper we derive hypotheses why exercise could also be beneficial for this patient population.

The role of environmental influences in the complex relationship between borderline personality disorder and attention-deficit/hyperactivity disorder: review of recent findings

BACKGROUND

In recent years, the existence of possible developmental pathways from childhood Attention-Deficit/Hyperactivity Disorder (ADHD) to adult Borderline Personality Disorder (BPD) has been suggested. The existence of common genetic factors has been described but there is little evidence on the role of environmental factors in the possible transition from one disorder to another throughout life. The main goal of this work is to review the literature about the existing evidence on childhood traumas as factors that mediate the risk of developing BPD in children with ADHD.

METHODS

A literature search was conducted using PubMed, Science Direct and PsychInfo databases. Criteria included studies of BPD and ADHD relationships and childhood traumas as environmental influences from epidemiological or clinical samples.

RESULTS

The review only identified 4 studies that matched the search criteria. All studies retrospectively analyzed childhood traumas, and adult patients with BPD, with or without comorbid ADHD, were the most frequently mentioned. The analyzed evidence reinforces the relationship between the number of childhood traumas and higher clinical severity. Three of these analyzed studies describe an increased the risk of children with ADHD who report emotional and sexual traumatic experiences to develop BPD in adulthood.

CONCLUSIONS

The experience of traumatic childhood events, especially those of an emotional type, may have a mediating effect of an increased risk of developing adult BPD in childhood ADHD patients. However, to consider them as risk factors, more studies, and especially longitudinal studies, are necessary to clarify the probable transactional process between the two disorders. Evidence from these studies may be helpful to develop early intervention programs to reduce the functional impairment associated with the two disorders.

Validity and reliability of Persian translation of the Borderline Evaluation of Severity over Time (BEST) questionnaire

Background: Borderline Evaluation of Severity over Time (BEST) is one of the self-reported tools for evaluation of the severity and track the response of treatment of borderline personality disorder. The present study evaluated the validity and reliability of Persian Translation of the Borderline Evaluation of Severity over Time (BEST) Questionnaire and to compare it with a semi-structured clinical interview for DSM-IV axis II (SCID-II).

Methods: The questionnaire was translated into Persian and then, the content and face validities of the questionnaire were determined. The translated BEST questionnaire and SCID-II were conducted on 33 outpatients and 32 hospitalized patients with diagnosis of borderline personality disorder and 30 patients’ companions. Forty-five patients completed the questionnaire again in an interval between 7 to 45 days. The data were analyzed using exploratory factor analysis, paired sample t-test, and the Pearson correlation coefficient and Cronbach’s α coefficient.

Results: This study evaluates the content validity, face validity, and criterion validity and reliability of the Persian version of the BEST Questionnaire. The mean scores of the BEST questionnaire were 45.6, 39.2, and 24.3 in in-patients, outpatients, and controls, respectively (p=0.001). The mean scores of the BEST questionnaire were 43.7 in the first evaluation, and 41.4 in the second one (r=0.619, p<0.001). Cronbach’s α coefficient was 0.761, and it reached to 0.898 after omitting items 13 to 15. The questionnaire had a two-factor structure, including internal turmoil and the disturbance in interpersonal relationships.

Conclusion: The Persian version of the BEST Questionnaire has a high face and content validity, high criterion validity, moderate to high reliability, and an acceptable two-factor structure.

A history of prolonged childhood sexual abuse is associated with more severe clinical presentation of borderline personality disorder in adolescent female inpatients - A naturalistic study

BACKGROUND

Borderline personality disorder (BPD) is associated with high rates of suicidal and self-injurious behaviors and a substantial proportion of BPD patients have a history of trauma, particularly childhood sexual abuse (CSA).

OBJECTIVE

To compare the clinical presentation severity in female adolescent inpatients with BPD with and without history of prolonged CSA.

PARTICIPANTS AND SETTING

Female adolescent BPD patients admitted to a psychiatric inpatient unit.

METHODS

A retrospective analysis of records of the inpatients, divided into two groups: with (n = 38) and without (n = 40) a history of prolonged CSA. Prolonged CSA was defined as sexual abuse continuing for at least 3 months. Demographic and clinical data, including number and duration of psychiatric hospitalizations until the age 19, non-suicidal self-injury (NSSI), suicide attempts, cigarette smoking, alcohol and drug use, and sexual impulsivity were compared between the two groups.

RESULTS

The BPD + prolonged CSA group had a larger duration of the first psychiatric hospitalization, number of hospitalizations and cumulative length of hospitalizations compared with the control group. Furthermore, the BPD + prolonged CSA group had a higher number of suicidal attempts, and higher rates of severe NSSI events, cigarette smoking, alcohol use, and sexual impulsivity.

CONCLUSIONS

This study demonstrated for the first time that adolescent female BPD inpatients with a history of prolonged CSA, manifest more severe clinical presentation compared to those without prolonged CSA. Hence, it appears essential to encourage therapists to inquire about history of CSA and refer adolescent female BPD inpatients with prolonged CSA to appropriate intensive therapy.

Family Connections in different settings and intensities for underserved and geographically isolated families: a non-randomised comparison study

BACKGROUND

Family Connections (FC) is a multi-family skills training program for relatives of individuals with borderline personality disorder (BPD) and related difficulties, typically offered once per week for 12-14 weeks. Families with loved ones receiving residential Dialectical Behaviour Therapy DBT (DBT-R) in a different community, or those with multiple caregiving demands may have difficulty participating in weekly standard FC (FC-S). The aims of this paper are to: 1) Evaluate the results of the FC-S approach compared with an intensified weekend FC model developed for family members whose relatives are in DBT-R (FC-R); 2) Evaluate outcomes of FC-R for families with loved ones returning home from DBT-R, as little is known about how this population fares.

METHODS

Data were collected at pre-treatment (T1), post-treatment (T2), and at six-to-seven-month follow-up (T3) in this non-randomized comparison study. A total of 82 family members participated, 34 of whom completed the FC-S program and 48 of whom completed the FC-R program. The evaluation was based upon outcomes derived from a standard battery used in FC research, analyzed by time and treatment setting. A composite score to evaluate family distress was generated. Two-way mixed multivariate analyses of variance (MANOVA) were employed to evaluate time (pre-versus-post versus follow-up) and group (FC-S versus FC-R).

RESULTS

Scores on measures of mental health difficulties (General Severity Index), sense of burden (Burden Assessment Scale), and Global Family Functioning showed improvement over time. Having a loved one return home from DBT-R was associated with worsening on the GSI and the BAS at post-test. Notably, this deterioration was not found at follow-up.

CONCLUSIONS

Little is known about families with loved ones receiving DBT-R other than the fact that their loved ones had not responded to previous services, which suggests greater complexity and chronicity. Because the family members receiving the weekend intensive FC-R version of FC demonstrated improvement, preliminary support exists for service providers to use the weekend intensive FC-R model as a time-and-cost efficient option whenever barriers exist to participating in weekly FC-S. Our findings also suggest that booster sessions may be indicated for families receiving loved ones home from DBT-R programs.

Differentiating BPD in adolescents with NSSI disorder: the role of adverse childhood experiences and current social relationships

BACKGROUND

As borderline personality disorder (BPD) is increasingly considered a lifespan developmental disorder, we need to focus on risk factors and precursors in the developmental pathways to BPD, in order to enable early detection and intervention. Within this developmental pathway, adolescence is a crucial phase in the light of the manifestation of the disorder. Relational factors such as adverse childhood experiences and current relational problems can be considered important in adolescents who are at-risk for BPD. Nonsuicidal self-injury (NSSI) is a key precursor for adolescent BPD and one of the most promising targets for early detection and intervention of BPD.

METHODS

In a clinical sample of 152 adolescents engaging in nonsuicidal self-injury (NSSI) disorder referred to mental healthcare in Germany, this study investigated whether we can differentiate who has BPD from 1) adverse childhood experiences; and 2) the quality of current relationships, both with parents and peers. BPD was assessed both categorically as a dichotomized score and dimensionally as a continuous score.

RESULTS

More adverse childhood experiences, but not low quality of current social relationships, were related to more BPD symptoms and an increased risk for meeting full criteria for BPD. In the dimensional model, current social relationship quality with parents and peers did not show a moderating (protecting or aggravating) effect on the association between adverse childhood experiences and BPD. Using a categorical approach, however, the association between childhood adversity and meeting full criteria for BPD was higher in individuals reporting higher quality of current parent-child relationship.

CONCLUSIONS

These results highlight adverse childhood experiences as risk factors of BPD, while the role of current social relationships seems more complex.

The prevalence and predictors of bipolar and borderline personality disorders comorbidity: Systematic review and meta-analysis

INTRODUCTION

Data about the prevalence of borderline personality (BPD) and bipolar (BD) disorders comorbidity are scarce and the boundaries remain controversial. We conducted a systematic review and meta-analysis investigating the prevalence of BPD in BD and BD in people with BPD.

METHODS

Two independent authors searched MEDLINE, Embase, PsycINFO and the Cochrane Library from inception till November 4, 2015. Articles reporting the prevalence of BPD and BD were included. A random effects meta-analysis and meta-regression were conducted.

RESULTS

Overall, 42 papers were included: 28 considering BPD in BD and 14 considering BD in BPD. The trim and fill adjusted analysis demonstrated the prevalence of BPD among 5273 people with BD (39.94 ± 11.78 years, 44% males) was 21.6% (95% CI 17.0-27.1). Higher comorbid BPD in BD were noted in BD II participants (37.7%, 95% CI 21.9-56.6, studies=6) and North American studies (26.2%, 95% CI 18.7-35.3, studies=11). Meta regression established that a higher percentage of males and higher mean age significantly (p<0.05) predicted a lower prevalence of comorbid BPD in BD participants. The trim and fill adjusted prevalence of BD among 1814 people with BPD (32.22 ± 7.35 years, 21.5% male) was 18.5% (95% CI 12.7-26.1).

LIMITATIONS

Paucity of longitudinal/control group studies and accurate treatment records.

CONCLUSIONS

BPD-BD comorbidity is common, with approximately one in five people experiencing a comorbid diagnosis. Based on current diagnostic constructs, and a critical interpretation of results, both qualitative and quantitative syntheses of the evidence prompt out the relevance of differences rather similarities between BD and BPD.

Network analysis of functional brain connectivity in borderline personality disorder using resting-state fMRI

Borderline personality disorder (BPD) is associated with symptoms such as affect dysregulation, impaired sense of self, and self-harm behaviors. Neuroimaging research on BPD has revealed structural and functional abnormalities in specific brain regions and connections. However, little is known about the topological organizations of brain networks in BPD. We collected resting-state functional magnetic resonance imaging (fMRI) data from 20 patients with BPD and 10 healthy controls, and constructed frequency-specific functional brain networks by correlating wavelet-filtered fMRI signals from 82 cortical and subcortical regions. We employed graph-theory based complex network analysis to investigate the topological properties of the brain networks, and employed network-based statistic to identify functional dysconnections in patients. In the 0.03–0.06 Hz frequency band, compared to controls, patients with BPD showed significantly larger measures of global network topology, including the size of largest connected graph component, clustering coefficient, small-worldness, and local efficiency, indicating increased local cliquishness of the functional brain network. Compared to controls, patients showed lower nodal centrality at several hub nodes but greater centrality at several non-hub nodes in the network. Furthermore, an interconnected subnetwork in 0.03–0.06 Hz frequency band was identified that showed significantly lower connectivity in patients. The links in the subnetwork were mainly long-distance connections between regions located at different lobes; and the mean connectivity of this subnetwork was negatively correlated with the increased global topology measures. Lastly, the key network measures showed high correlations with several clinical symptom scores, and classified BPD patients against healthy controls with high accuracy based on linear discriminant analysis. The abnormal topological properties and connectivity found in this study may add new knowledge to the current understanding of functional brain networks in BPD. However, due to limitation of small sample sizes, the results of the current study should be viewed as exploratory and need to be validated on large samples in future works.

•

We analyzed the topology and connectivity of functional brain networks in BPD.

•

Patients with BPD showed altered small-world properties and network efficiency.

•

Patients with BPD showed altered nodal centrality at specific brain regions.

•

An interconnected subnetwork showed significantly lower connectivity in BPD.

•

Key network measures were correlated with clinical symptom scores.

Body-related attentional biases in patients with posttraumatic stress disorder resulting from childhood sexual abuse with and without co-occurring borderline personality disorder

BACKGROUND AND OBJECTIVES

Disturbed body perception is a common characteristic of patients with posttraumatic stress disorder (PTSD) after childhood sexual abuse (CSA). We examined the extent to which biased information processing of body related stimuli was related to CSA.

METHODS

Patients with PTSD after CSA (PTSD group; n = 61) were compared to healthy controls (HC group; n = 30). The PTSD group was subdivided into patients with comorbid Borderline Personality Disorder (BPD; PTSD+ group) and patients without BPD (PTSD-group). We used an emotional Stroop task (EST) with body-related words to assess biased information processing.

RESULTS

Only patients in the PTSD+ group but not in the PTSD-group showed a significantly stronger attentional bias to body related words compared to the HC group (p = .009).

LIMITATIONS

Recruitment in in-patient setting might have led to a non-representative sample of PTSD patients. The PTSD patients were not characterized regarding anything other than the mentioned mental disorders. Potentially, the body related words may have been associated with offenders' body areas, but not with the patients.

CONCLUSION

We found that patients with PTSD and comorbid BPD had a stronger attentional bias towards body related stimuli in comparison to other groups. This suggests that the observed attentional bias is a product of CSA combined with the emotion regulation difficulties characteristic of BPD. Future studies should test whether directly targeting body-related abnormalities in information processing can improve existing treatments for patients with CSA and BPD.

Hostility and childhood sexual abuse as predictors of suicidal behaviour in Borderline Personality Disorder

Impulsivity is a multidimensional construct and has been previously associated with suicidal behaviour in borderline personality disorder (BPD). This study examined the associations between suicidal behaviour and impulsivity-related personality traits, as well as history of childhood sexual abuse, in 76 patients diagnosed with BPD using both the Structured Interview for Diagnostic and Statistical Manual of Mental Disorders III (DSM-III) Axis-II diagnoses and the self-personality questionnaire. Impulsivity-related traits were measured using the Barratt Impulsiveness Scale-11 (BIS-11), the Buss-Durkee Hostility Inventory (BDHI) and the Temperament and Character Inventory-Revised (TCI-R). We found that hostility and childhood sexual abuse, but not impulsivity or other temperament traits, significantly predicted the presence, number and severity of previous suicide attempts. Hostility traits and childhood sexual abuse showed an impact on suicide attempts in BPD. Our results support previous findings indicating that high levels of hostility and having suffered sexual abuse during childhood lead to an increased risk for suicidal behaviour in BPD.
