New episodes and new onsets of major depression in borderline and other personality disorders

Symptom Overlap Between Depression and Borderline Personality Disorder: A Network Analysis

Major depression (MD) is a serious mental health disorder projected to become the leading cause of global disability by 2030. Borderline personality disorder (BPD) frequently co-occurs with MD. Individuals with both conditions often experience prolonged recovery times and exhibit high levels of suicidal behaviour. Network theory and its application, network analysis, presents a novel framework for conceptualising and understanding the comorbidity between MD and BPD. This network analysis aims to identify influential symptoms within a BPD/MD network and explore the clinical relevance of these relationships. Data from 548 participants were pooled from four clinical trials run between 1994 and 2013 at the Department of Psychological Medicine, University of Otago, Christchurch, New Zealand. All participants were diagnosed with current MD (as part of major depressive disorder or bipolar II disorder). Baseline MD and BPD symptom data from trial entry assessments were entered into a cross-sectional network analysis. A further network analysis was estimated with the addition of three covariates (age, gender and depression severity) alongside the MD and BPD symptoms. Network analyses identified several connecting symptoms between MD and BPD. After controlling for depression severity, BPD symptoms of identity disturbance and unstable relationships had unique and robust relationships with MD suicidal ideation and behaviours. Further exploration of these bridge relationships found that participants who exhibited identity disturbance were almost three times more likely to have reported a previous suicide attempt. Results from this study have implications for risk assessment and treatment of individuals with comorbid MD and BPD.

Neurobiological correlates of personality dimensions in borderline personality disorder using graph analysis of functional connectivity

Borderline personality disorder (BPD) is is a type B personality disorder primarily characterized by a pattern of unstable interpersonal relationships, a distorted self-concept, and intense emotional reactions, associated with extreme and opposing mental and behavioral states, which coexist and lead to destructive behaviors such as self-harm, commonly recurring over time.. The Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fifth Edition (PID-5) provides a dimensional assessment of maladaptive domains associated with personality disorders, improving the understanding of their complex clinical presentations. While altered brain functional connectivity (FC) has been reported in BPD, neurobiological-clinical correlations remain debated. This study explores the relationship between the personality dimensions of BPD and resting-state fMRI (rs-fMRI) FC. Twenty-eight patients with BPD (6M/22F, 23.7 ± 3.4 years) and twenty-eight matched healthy controls (6M/22F, 24.3 ± 2.8 years) underwent a psychiatric assessment, including the PID-5, and an MRI protocol including rs-fMRI. Functional data were analyzed via graph theory to derive network properties at global and nodal levels, which were correlated with the PID-5 subdomains. The results revealed impairments across all personality trait facets. Patients had lower global connectivity and compromised centrality of several limbic structures and frontotemporal regions. Significant correlations were found between separation insecurity and global efficiency (R = 0.60, adjusted-p = 0.035) and between depressivity and the degree of the left middle temporal gyrus (R = 0.69, adjusted-p = 0.023) in females. These findings suggest links between negative affectivity traits, in particular separation insecurity and depressivity, and specific brain network dysfunctions in BPD.

"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.

Mentalizing deficits in borderline personality disorder related to axis I comorbidity: Clinical relevance

AIM

Deficits in mentalization have been described in several mental disorders, but information is still scarce and ambiguous about the types of mentalization errors in each disorder and their specificity and severity in borderline personality disorder (BPD). Due to the high comorbidity between this disorder and axis I disorders, the aim of this work is to study differences in mentalization responses in BPD considering the different comorbidity profiles with other disorders.

METHODS

A total of 141 BPD patients were evaluated using The Mini-International Neuropsychiatric Interview (MINI), to identify comorbid axis I disorders. Mentalizing ability was assessed by the Movie for the Assessment of Social Cognition (MASC). Statistical associations were analysed into the different variables.

RESULTS

Patients with comorbid BPD and anorexia nervosa (AN), suicidal behaviour disorder or post-traumatic stress disorder (PTSD) respectively presented higher overmentalization, undermentalization and absence of mentalization errors, compared with patients with BPD without comorbidity.

CONCLUSIONS

Results show that BPD comorbidity with AN, suicidal behaviour disorder and PTSD affect to the types and severity of mentalizing deficits observed in these patients. This study highlights the importance of the assessment and treatment of axis I comorbid disorders in borderline personality disorder, with the objective of shaping personalized treatment for every patient.

Preliminary findings of a randomized controlled trial investigating the efficacy of transcranial magnetic stimulation in treatment-resistant depression: a post-hoc analysis on the role of co-occurring personality disorders

Introduction

Despite the high hopes for the use of transcranial magnetic stimulation (TMS) in the treatment of depression, between 30% and 60.5% of patients do not respond to stimulation. The factors contributing to non-response, especially those related to personality, remain insufficiently investigated. The main aim of our study was to compare the efficacy of active TMS and sham-placebo protocols in combined therapy of treatment-resistant depression with evaluation of possible personality disorders comorbidity.

Methods

The study was conducted between December 2019 and December 2022, as a randomized, double-blind, active comparator-controlled and sham-controlled parallel trial. Patients (n = 41) were randomized into one of two experimental conditions (active TMS vs. placebo) and screened before and after stimulation as well as at a 3-month follow-up. Personality disorders were assessed with The Structured Clinical Interview for DSM-5 Personality Disorders.

Results

There were no significant differences between the TMS active and sham groups in terms of general characteristics, coexisting personality disorders, and Montgomery-Åsberg Depression Rating Scale scores before stimulation, at the end of stimulation, and after 3 months of stimulation. However, linear regression analysis revealed significant negative associations between the coexistence of personality disorders and the reduction of depressive symptoms from baseline to the end of stimulation. The post-hoc exploratory analysis on the first phase of the RCT confirmed the presence of personality disorders to be a consistent negative influence on the reduction of depressive symptoms post-stimulation, regardless of protocol and experimental condition and demonstrated a smaller percentage reduction in depressive symptoms after stimulation in patients with personality disorders.

Discussion

A central conclusion, based on our study, is that transcranial magnetic stimulation for treatment-resistant depression cannot be considered as a method independent of co-occurring personality disorders.

Treating depression in patients with borderline personality disorder: clinical clues on the use of antidepressants

Personality disorders (PD) are described as enduring patterns of markedly deviant and pervasive inner experiences and behaviors, with onset in adolescence, which lead to severe distress or impairment. Patients suffering from major depressive disorder (MDD) display higher rates of comorbidity with personality disorders, often complicating the treatment, and worsening the outcomes. Borderline personality disorder (BPD) is the most common of PD and is frequently associated with MDD, with which shares several features. The most part of research agrees on the fact that comorbid BPD in MDD patients quite doubles the poor response to treatments. Moreover, no treatment strategy stands out currently to emerge as more effective in these cases, thus urging the call for the need of new approaches. Herein, we revise the current literature on BPD, its neurobiology and comorbidity with MDD, as well as the more recent treatment strategies used. Then, based on its pharmacology, we propose a possible role of trazodone as a valuable tool to approach comorbid BPD-MDD.

The relationship between depressive mood and non-suicidal self-injury among secondary vocational school students: the moderating role of borderline personality disorder tendencies

Background

Non-suicidal self-injury (NSSI) has become an important public health issue of global concern, often occurring in adolescents, and depressive mood is closely related to NSSI. In addition, NSSI is considered a symptom of borderline personality disorder. It has been found that adolescents in secondary vocational schools are more vulnerable to behavior and emotional disorders than those in general high schools. This study investigated the risk factors associated with NSSI affecting secondary vocational school students and analyzed the role of borderline personality disorder tendencies in promoting the occurrence of NSSI among students with depressive moods.

Methods

A total of 1,848 Chinese secondary vocational students completed a self-report questionnaire. The homemade NSSI behavior questionnaire, Patient Health Questionnaire-9 and Personality Diagnostic Questionnaire-4 were used in this survey. Binary logistic regression and PROCESS software analysis were used to explore the influencing factors associated with NSSI and to test for moderating effects.

Results

Female (OR = 3.412, 95% CI 2.301-5.060), drinking history (OR = 2.007, 95% CI 1.383-2.911), history of suicidal death exposure (OR = 3.161, 95% CI 1.999-4.999), depressive mood (OR = 2.436, 95% CI 1.668-3.558) and borderline personality disorder tendencies (OR = 2.558, 95% CI = 1.764-3.711) were independent risk factors for NSSI. Borderline personality disorder tendencies (B = 0.047, p = 0.000) moderated the relationship between depressive mood and NSSI. The stronger the borderline personality tendencies, the more NSSI behavior occurred when they were depressive.

Conclusions

Borderline personality disorder tendencies in secondary vocational school adolescents significantly enhance the association of depressive mood with NSSI. There is a moderating role for borderline personality disorder tendencies in depressive mood and NSSI.

Exploring the Utility of Neurostimulation Therapies in the Treatment of Borderline Personality Disorder: A Systematic Literature Review

ABSTRACT

The use of electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS) in the treatment of people diagnosed with borderline personality disorder (BPD) highlights the need for systematic review of the evidence supporting this practice. A comprehensive literature search identified seven original clinical research studies investigating the use of brain stimulation therapies in people diagnosed with BPD. The lack of consistent study design, diagnostic methodology, treatment parameters, and outcome measures precluded analysis of aggregated study results. There were no ECT studies evaluating BPD symptom outcomes; however, studies of ECT in patients with comorbid BPD and depression suggested that depressive symptoms were less responsive to ECT compared with depression-only patients. The few studies available suggest that TMS may lead to clinically and statistically significant improvements in BPD symptoms and depressive symptoms. Similar overall improvements were reported despite the use of heterogeneous TMS treatment protocols, highlighting the importance of including a sham condition to investigate the contribution of the placebo effect to overall improvement. There is still no clear evidence supporting the use of ECT for treating people with BPD (with or without depression); therefore, the use of ECT in this population should be approached with caution. Although TMS shows early promise, the low numbers of participants in the few available studies suggest the urgent need for larger randomized controlled trials to provide an evidence base for this increasingly popular treatment.

Common and distinct patterns of gray matter alterations in young adults with borderline personality disorder and major depressive disorder

Young adults with borderline personality disorder (BPD) and major depressive disorder (MDD) have a relatively high comorbidity rate; however, whether they share a neurobiological basis remains controversial. Although previous studies have reported respective brain alterations, the common and distinct gray matter changes between two disorders are still inconsistent. We conducted a meta-analysis using anisotropic effect size-based algorithms (ASE-SDM) to identify consistent findings from whole-brain voxel-based morphometry (VBM) studies of gray matter volume (GMV) in 274 young adults (< 45 years old) with BPD and 1576 with MDD. Compared with healthy controls, the young adults with BPD showed GMV reduction mainly in the prefrontal cortex including the inferior frontal gyrus and superior frontal gyrus, medial temporal network, and insula, whereas the MDD showed GMV alteration in the visual network (fusiform gyrus and inferior temporal gyrus), sensorimotor network (bilateral postcentral gyrus (PoCG) and right cerebellum) and left caudate nucleus. The GMV differences between these two disorders were concentrated in the left orbitofrontal cortex, cingulate cortex, right insula, and cerebellum. The meta-regression of the MDD group showed a negative association between disease duration and the right middle cingulate gyrus as well as negative associations between depressive symptoms and brain regions of the right cerebellum and the left PoCG. Our results identified common and distinct patterns of GMV alteration between BPD and MDD, which may provide neuroimage evidence for the disorder comorbidity mechanisms and partly indicate the similar and different biological features in emotion regulation of the two disorders. This study was registered with PROSPERO (CRD42020212758).

Epicardial adipose tissue and adrenal gland volume in patients with borderline personality disorder

Borderline personality disorder (BPD) is associated with an elevated mortality risk that is partially attributed to suicide, but few studies examined other possible causes of premature death. The present study compared epicardial adipose tissue (EAT) volume as a known early predictor of premature cardiovascular morbidity, cardiovascular risk indices, and adrenal gland volume (AGV) as an indicator for chronic hypothalamus-pituitary-adrenal (HPA) axis activation in females with borderline personality disorder (BPD), major depressive disorder (MDD) and in healthy individuals. Twenty-eight patients with BPD comorbid with MDD (BPD/MDD), 22 MDD patients and 26 healthy females (CTRL) of comparable age were included. EAT and AGV were assessed by magnetic resonance tomography; 10-year cardiovascular risk and diabetes risk were determined by PROCAM and FINDRISK score; metabolic syndrome was defined following National Cholesterol Education Adult Treatment Panel III R (NCEP/ATP III) criteria. MADRS was used to assess depression severity. After adjustment for age, body mass index (BMI), and physical activity, EAT and AGV were significantly increased in BPD/MDD compared to MDD and CTRL. EAT and AGV displayed a positive correlation. Finally, diabetes risk in BPD/MDD was elevated compared to CTRL and MDD. The present study highlights the increased cardiometabolic risk of BPD patients. We identify EAT accumulation as an early predictor and potential mediator of cardiovascular disease in BPD that appears to be driven at least in part by HPA axis dysregulation. Therefore, interventions that reduce EAT volume (i.e. exercise and diet) should be considered in the clinical management of BPD.

Insomnia partially mediates the relationship between pathological personality traits and depression: a case-control study

Background and Objective

Personality disorders are frequently associated with insomnia and depression, but little is known about the inter-relationships among these variables. Therefore, this study examined these inter-relationships and the possible mediating effect of insomnia on the association between specific personality pathologies and depression severity.

Methods

There were 138 study participants, including 69 individuals with depression and 69 healthy controls. The main variables were measured by the Hamilton Depression Rating Scale-24 (HAMD-24), Athens Sleep Insomnia Scale (AIS), and the Personality Diagnostic Questionnaire (PDQ-4+). Multivariate linear regression and mediation analysis were conducted.

Results

With the exception of the antisocial personality score, all the PDQ-4+ scores and AIS scores were significantly higher in the depression group than in the healthy control group (p < 0.001). In the total sample, all personality pathology scores (p < 0.001), except the antisocial personality score, had significant positive correlations with the AIS scores and HAMD-24 scores, and the AIS scores and HAMD-24 scores were positively correlated (r = 0.620, p < 0.001). Regression analysis revealed that borderline personality, passive-aggressive personality, and insomnia positively predicted the severity of depression, after adjusting for sociodemographic covariates, and that insomnia partially mediated the associations of borderline personality and passive-aggressive personality with depression severity.

Conclusions

Borderline personality, passive-aggressive personality, and insomnia tend to increase the severity of depression, and the effect of borderline and passive-aggressive personality on depression severity may be partially mediated by insomnia. This is the first study to report these findings in a Chinese sample, and they may help researchers to understand the pathways from specific personality pathologies to the psychopathology of depression better, which should be useful for designing interventions to relieve depression severity, as the impact of specific personality pathology and insomnia should be considered.

Naturalistic Research on Recovery Processes: Looking to the Future

Because recovery is an ongoing process, conducting research on the recovery process presents multiple challenges. The process can play out over many years, but change also can occur quickly. Although researchers are keenly interested in the precursors of these sudden changes, a researcher is unlikely to be present at critical moments; however, technology offers new options not available in prior years. Recovery research at this point, however, must be pursued largely through observational methods. Experiments involving aspects of recovery can and should be done, but observation is an essential part of recovery research. Hence, this paper focuses on technologies for conducting and analyzing observational studies. The author briefly reviews methods for gathering intensive longitudinal data and discusses how recovery researchers can take advantage of existing technology to delve more deeply into the complex processes associated with recovery and relapse. The future of recovery research, however, will require examining new ways of investigating recovery phenomena, including a new option for gathering data based on decision theory. Taking maximum advantage of existing and new technology for recovery research will require increasing collaboration between recovery researchers and quantitative scientists.

Schema therapy versus cognitive behavioral therapy versus individual supportive therapy for depression in an inpatient and day clinic setting: study protocol of the OPTIMA-RCT

BACKGROUND

Major depressive disorder represents (MDD) a major cause of disability and disease burden. Beside antidepressant medication, psychotherapy is a key approach of treatment. Schema therapy has been shown to be effective in the treatment of psychiatric disorders, especially personality disorders, in a variety of settings and patient groups. Nevertheless, there is no evidence on its effectiveness for MDD in an inpatient nor day clinic setting and little is known about the factors that drive treatment response in such a target group.

METHODS

In the current protocol, we outline OPTIMA (OPtimized Treatment Identification at the MAx Planck Institute): a single-center randomized controlled trial of schema therapy as a treatment approach for MDD in an inpatient and day clinic setting. Over the course of 7 weeks, we compare schema therapy with cognitive behavioral therapy and individual supportive therapy, conducted in individual and group sessions and with no restrictions regarding concurrent antidepressant medication, thus approximating real-life treatment conditions. N = 300 depressed patients are included. All study therapists undergo a specific training and supervision and therapy adherence is assessed. Primary outcome is depressive symptom severity as self-assessment (Beck Depression Inventory-II) and secondary outcomes are clinical ratings of MDD (Montgomery-Asberg Depression Rating Scale), recovery rates after 7 weeks according to the Munich-Composite International Diagnostic Interview, general psychopathology (Brief Symptom Inventory), global functioning (World Health Organization Disability Assessment Schedule), and clinical parameters such as dropout rates. Further parameters on a behavioral, cognitive, psychophysiological, and biological level are measured before, during and after treatment and in 2 follow-up assessments after 6 and 24 months after end of treatment.

DISCUSSION

To our knowledge, the OPTIMA-Trial is the first to investigate the effectiveness of schema therapy as a treatment approach of MDD, to investigate mechanisms of change, and explore predictors of treatment response in an inpatient and day clinic setting by using such a wide range of parameters. Insights from OPTIMA will allow more integrative approaches of psychotherapy of MDD. Especially, the identification of intervention-specific markers of treatment response can improve evidence-based clinical decision for individualizing treatment.

Symptoms of depersonalization/derealization are independent risk factors for the development or persistence of psychological distress in the general population: Results from the Gutenberg health study

BACKGROUND

Symptoms of depersonalization (DP) and derealization (DR) have a high prevalence in patient and community samples. Previous studies suggested that DP/DR symptoms might represent a marker of disease severity and poor prognosis. However, population-based studies investigating the impact of DP/DR symptoms on the course of depression and anxiety are sparse. Therefore, we aimed to analyze whether symptoms of DP/DR are longitudinally associated with the persistence or incidence of elevated symptoms of depression/anxiety.

METHODS

We analyzed observational data from a sample of 13.182 participants of the Gutenberg Health Study. The outcomes were elevated symptoms of depression/anxiety at the 2.5 years follow-up as determined by the 2-item depression scale (PHQ-2), the 2-item anxiety scale (GAD-2), and the compound measure PHQ-4 respectively. The predictor was the 2-item Cambridge Depersonalization Scale (CDS-2).

RESULTS

8.7% of the sample were bothered by symptoms of DP/DR at baseline. They had an increased risk for elevated symptoms of depression/anxiety at the 2.5-year follow-up beyond baseline depression/anxiety and other factors. Each point increment in the CDS-2 scale, ranging from 0-6, was associated with a 21% increase of risk for PHQ-4 ≥ 3 at the follow-up (odds ratio 1.21, 95% confidence interval 1.11-1.32).

LIMITATIONS

The study was mostly questionnaire-based.

CONCLUSION

Symptoms of DP/DR are independent risk factors for the persistence or incidence of elevated symptoms of depression/anxiety. Symptoms of DP/DR represent an easily assessable risk factor for the course of mental disorders. Treatment and prevention of mental disorders might benefit from the broader recognition of these phenomena.

Cortical haemodynamic response measured by functional near infrared spectroscopy during a verbal fluency task in patients with major depression and borderline personality disorder

BACKGROUND

Functional near infrared spectroscopy (fNIRS) provides a direct and quantitative assessment of cortical haemodynamic function during a cognitive task. This functional neuroimaging modality may be used to elucidate the pathophysiology of psychiatric disorders, and identify neurophysiological differences between co-occurring psychiatric disorders. However, fNIRS research on borderline personality disorder (BPD) has been limited. Hence, this study aimed to compare cerebral haemodynamic function in healthy controls (HC), patients with major depressive disorder (MDD) and patients with BPD.

METHODS

fNIRS signals during a verbal fluency task designed for clinical assessment was recorded for all participants. Demographics, clinical history and symptom severity were also noted.

FINDINGS

Compared to HCs (n = 31), both patient groups (MDD, n = 31; BPD, n = 31) displayed diminished haemodynamic response in the frontal, temporal and parietal cortices. Moreover, haemodynamic response in the right frontal cortex is markedly lower in patients with MDD compared to patients with BPD.

INTERPRETATION

Normal cortical function in patients with BPD is disrupted, but not as extensively as in patients with MDD. These results provide further neurophysiological evidence for the distinction of patients with MDD from patients with BPD.

The 24-year course of major depression in patients with borderline personality disorder and personality-disordered comparison subjects

BACKGROUND

This study had two main objectives. The first was to detail the prevalence of major depressive disorder over 24 years of follow-up for both patients with borderline personality disorder (BPD) and comparison subjects with other personality disorders (OPD). The second was to determine time-to-remission, recurrence, and new onset of major depression among these two groups of patients.

METHODS

The SCID-I was administered to 290 borderline inpatients and 72 personality-disordered comparison subjects during their index admission. It was also re-administered at 12 contiguous two-year follow-up periods.

RESULTS

The prevalence of major depression was significantly higher for borderline patients over time but declined significantly over time for those in both study groups. In terms of time to events, 93% of borderline patients meeting criteria for major depression at baseline experienced a two-year remission by the time of the 24-year follow-up. Recurrences were about as common (90% for those with remitted major depression). New onsets of major depression were also very common (86% for those without major depression during their index admission).

LIMITATIONS

Results may not pertain to less severely ill patients with BPD and those in less treatment.

CONCLUSIONS

Taken together, the results of this study suggest that the remitting-recurring course of major depression in borderline patients is very similar to the course of major depression in those with other types of personality disorder and those for whom major depression is their primary disorder.

Effectiveness of Electroconvulsive Therapy in Patients With Major Depressive Disorder and Comorbid Borderline Personality Disorder

OBJECTIVE

Previous research suggests that electroconvulsive therapy (ECT)-the criterion standard for the treatment of severe depression-is not as effective when the patient has comorbid borderline personality disorder (BPD). The ECT outcomes of patients with and without BPD were compared in a retrospective chart review to test this claim.

METHODS

We enrolled 137 patients with a diagnosis of major depressive disorder who completed the McLean Screening Instrument for Borderline Personality Disorder. Twenty-nine patients had positive screening scores for BPD. The difference in Patient Health Questionnaire (PHQ-9) scores before and after ECT was compared between patients with and without BPD. Follow-up PHQ-9 scores determined after treatment were collected and analyzed.

RESULTS

Electroconvulsive therapy equally improved symptoms of depression as measured by PHQ-9 score in both patients who screened positive and patients who screened negative for BPD. No difference in the increase in PHQ-9 scores between these 2 groups was noted 1 month after treatment (P = 0.19).

CONCLUSIONS

These data showed that a positive BPD screen does not necessarily predict a poorer response to ECT, nor does it predict greater symptom recurrence after ECT. This does not suggest that ECT is necessarily an appropriate treatment for major depressive disorder in patients with a comorbid BPD, given the limitations of screening instruments.

Predictors of Slower Time-to-Cessation of Individual Therapy for Borderline Patients Over 16 Years of Prospective Follow-Up

The current study assesses time-to-cessation of individual therapy for patients with borderline personality disorder (BPD) and comparison subjects with other personality disorders (OPD) after 16 years of prospective follow-up. It also details the multivariate factors that predict this outcome for those with BPD. At baseline, 290 patients met criteria for BPD and 72 met criteria for OPD. Individuals with BPD had a significantly slower time-to-cessation of individual therapy than OPD comparison subjects. Seven baseline variables were found to be significant multivariate predictors of a slower time-to-cessation of individual therapy: older age, being white, severity of childhood neglect, history of a mood disorder, an IQ less than 90, poor vocational record prior to index admission, and higher level of trait neuroticism. The results of this study suggest that prediction of slower time-to-cessation of individual therapy is multifactorial in nature, involving factors related to demographics, childhood adversity, comorbidity, individual competence, and temperament.

Co-Morbidity of DSM-IV Personality Disorder in Major Depressive Disorder Among Psychiatric Outpatients in China: A Further Analysis of an Epidemiologic Survey in a Clinical Population

Introduction: It is common that personality disorder (PD) co-occurs with major depressive disorder (MDD). In the current literature, there is a dearth of information on the co-occurrence of PD and MDD among Chinese population. Materials and Methods: 609 individuals were randomly sampled from outpatients diagnosed as MDD in Shanghai Mental Health Center. Co-morbidity of PDs was assessed using the Personality Diagnostic Questionnaire Fourth Edition Plus (PDQ-4+) and eligible subjects were interviewed with the Structured Clinical Interview for DSM-IV Axis II (SCID-II). The score of PDQ-4+ and the rate of SCID-II PD between subjects diagnosed with MDD and those with anxiety disorders (AD) were compared. Results: Two hundred fifty-eight outpatients (42.36%) with MDD were recognized to possess at least one criterion of diagnosis for PD, according to the DSM-IV. The most prevalent PD was depressive PD (14.61%), followed by avoidant (11.49%) and borderline (11.49%) PD. Cluster C PDs (anxious and panic PD) were the most common PD types (12.12%) when compared to other clusters. Compared to patients with AD, individuals with MDD were significantly more likely to have paranoid PD (6.6% vs. 3.3%, p = 0.011), borderline PD (11.5% vs. 3.7%, p = 0.000), passive-aggressive PD (5.6% vs. 2.4%, p = 0.007), and depressive PD (14.6% vs. 7.8%, p = 0.000). Discussion: The finding indicates that there is a high prevalence of PD among patients with MDD. More significant co-morbidity rates of PDs in MDD have been found when compared with AD. Further studies for the longitudinal impact of the PD-MDD co-morbidity are in need.

Comorbidity of Borderline Personality Disorder: Current Status and Future Directions

Patients with borderline personality disorder have high rates of comorbid mood, anxiety, substance use, and eating disorders. The longitudinal studies conducted on borderline patients over 10 years of prospective follow-up suggest that patients with borderline personality disorder experienced declining rates of Axis I disorders over time, but the rates of these disorders remained high compared with those with other personality disorders. In addition, patients whose borderline personality disorder remitted over time experienced a substantial decline in all comorbid Axis I disorders, but those whose borderline personality disorder did not remit over time, reported stable rates of comorbid disorders.

Early life stress, resilience and emotional dysregulation in major depressive disorder with comorbid borderline personality disorder

BACKGROUND

Borderline personality disorder (BPD) show different course and treatment compared to major depressive disorder (MDD). Early life stress may increase BPD onset; however, resilience may play a protective role against the development of psychopathology. The goal of this study was to compare the early life stress, resilience, and the clinical characteristics of emotional dysregulation in patients with MDD with and without comorbid BPD.

METHODS

Thirty patients with both BPD and MDD, 25 patients with MDD alone, and 25 age- and sex- matched healthy controls, participated in this study. Analysis of variance was used to compare the early life stress, resilience, and emotional dysregulation among groups. Also, multivariate logistic regression models were used to identify the relationship of the early life stress and resilience domains with BPD comorbidity within MDD patients.

RESULTS

The domains of emotional abuse and self-regulation ability were significantly associated with BPD comorbidity and BPD severity. In emotional dysregulation, difficulty scores of impulsivity, coping strategies, and emotion clarity domains were significantly increased in patients with both BPD and MDD compared to patients with MDD alone.

LIMITATIONS

The relatively small sample size may contribute to reduce statistical power of investigation.

CONCLUSIONS

Emotional abuse experiences in early life, and deficits in self-regulation, are significantly associated with comorbid BPD in patients with MDD. A comprehensive evaluation including early life stress, resilience and emotion regulation ability may help to identify comorbid BPD in patients with MDD and develop treatment strategies.

Risk stratification for the early diagnosis of borderline personality disorder using psychiatric co-morbidities

AIM

To develop a risk stratification model for the early diagnosis of borderline personality disorder (BPD) using Taiwan National Health Insurance Research Database.

METHODS

We conducted a retrospective case-control study of 6132 patients (292 BPD patients and 5840 control subjects) who were selected from the National Health Insurance Research Database. Psychiatric co-morbidities including depressive disorder, bipolar disorder, anxiety disorder, substance-use disorder, personality disorders other than BPD, sleep disorder, eating disorder, autistic spectrum disorder, mental retardation and attention-deficit hyperactivity disorder, which were diagnosed within 3 years before enrolment, were collected. A logistic regression was used to calculate the odds ratio of psychiatric co-morbidities between subjects with and without BPD. The classification and regression tree method was used to generate a risk stratification model.

RESULTS

The odds ratios for depressive disorder, bipolar disorder, anxiety disorder, substance-use disorder, personality disorders other than BPD, sleep disorder, eating disorder, mental retardation and attention-deficit hyperactivity disorder were greater for BPD patients than for the control subjects. Furthermore, the risk of BPD can be reliably estimated using age and psychiatric co-morbidities including bipolar disorder, substance-use disorder and depressive disorder.

CONCLUSIONS

Most psychiatric disorders were more common in BPD patients than in the control subjects. Using psychiatric co-morbidities, we identified four variables as significant risk predictors of BPD and permitted identification of subjects with low, intermediate or high risk for BPD. The accuracy of the risk stratification model is high and can be easily applied in clinical practice.

Predictive Utility of Personality Disorder in Depression: Comparison of Outcomes and Taxonomic Approach

There is debate around the best model for diagnosing personality disorder, both in terms of its relationship to the empirical data and clinical utility. Four randomized controlled trials examining various treatments for depression were analyzed at an individual patient level. Three different approaches to the diagnosis of personality disorder were analyzed in these patients. A total of 578 depressed patients were included in the analysis. Personality disorder, however measured, was of little predictive utility in the short term but added significantly to predictive modelling of mediumterm outcomes, accounting for more than twice as much of the variance in social functioning outcome as depression psychopathology. Personality disorder assessment is of predictive utility with longer timeframes and when considering social outcomes as opposed to symptom counts. This utility is sufficiently great that there appears to be value in assessing personality; however, no particular approach outperforms any other.

Comparison of early maladaptive schemas between borderline personality disorder and chronic depression

Borderline personality disorder (BPD) and chronic depression (CD) are common and challenging mental disorders. Maladaptive cognitive schemas have been proposed to increase vulnerability to both disorders. In order to elucidate the role of maladaptive cognitive schemas in BPD and CD, this study compared psychiatric outpatients with BPD (N = 30) and CD (N = 30) in terms of early maladaptive schemas (EMSs). The groups were compared using the Young Schema Questionnaire short form-extended (YSQ-S2-extended) and the 15D health status questionnaire. BPD patients showed higher endorsement on the majority of EMSs, poorer social functioning, and greater concurrent distress than CD patients. However, after controlling for concurrent effects of psychological distress, the groups did not differ in 14 out of the 18 EMSs. These findings point to significant similarities in maladaptive beliefs between the 2 disorders and do not support broad, specific patterns of EMSs associated with either disorder. The results highlight the need for further study of the role of maladaptive schemas in the development and treatment of chronic mental disorders.

Personality Disorder and Alcohol Use Disorder: An Overview

BACKGROUND

Clinically, personality disorder (PD) commonly coexists with alcohol use disorder (AUD), although within mainstream mental health services both of these mental disorders are routinely overlooked. Despite a rich literature examining the interactions between AUD and personality functioning, personality traits, and PD, there remains conflicting evidence as to the degree of association and impact of one on the other.

METHODS

A narrative review and a synthesis of the literature were done.

RESULTS

The lifetime prevalence of AUD approaches 50% in some PD populations. The rates of PD in AUD populations are less clear but likely similar. Personality influences outcomes in AUD regardless of whether a categorical personality diagnosis or dimensional trait domain approach is taken. There are, however, no good data to inform clinicians on the impact of AUD on the outcomes of PD. Understanding the extent of this impact is complicated by the multiple tools used for diagnosis (of both PD and AUD) and the statistical methods used. Overall, caution is required in interpreting the data due to the quality of the current literature; however, comorbidity between the two disorders is likely significant and the impact of PD on AUD outcomes is sufficient to require consideration.

CONCLUSIONS

From a research perspective, better agreement on both diagnoses and outcomes is urgently needed to improve the overall quality of the evidence. Clinically, despite the limitations in the literature, it is unacceptable for PD services to ignore AUD and for AUD services not to screen for PD. Both are likely to have an impact on health and functioning and should be considered in routine reviews. A better conceptualization of the putative mechanisms of this interaction, as well as an understanding of the neurobiology and reasons for the impact on treatment outcomes, will help to move the field forward.

Emotion Regulation and Social Cognition as Functional Targets of Mechanism-Based Psychotherapy in Major Depression With Comorbid Personality Pathology

This article characterizes functional systems as targets of integrated modular psychotherapy for episodes of major depression (MD) with a comorbid condition of borderline personality disorder (BPD) or chronic depression (CD). Both types of comorbidities to MD are conceptualized as a trait-like concept dominated by impairments in interpersonal functioning. Despite differences in psychopathology, existing data show significant similarities in impairments of emotion regulation and social cognition in BPD and CD, thought to reflect common disease mechanisms linked to early-life adversity. The preexistence of BPD and CD and related functional impairments inhibits the remission of episodic MD and calls for mechanism-based interventions that complement existing treatments of MD by targeting these dysfunctions. Contemporary methods of psychotherapy already provide interventions to address such complicated states of comorbidity by specifically improving dysfunctions of emotion regulation and social cognition. We suggest a layout of modular interventions that can address identified dysfunctions in comorbid MD.

Predicting Nonsuicidal Self-Injury in Borderline Personality Disorder Using Ecological Momentary Assessment

Borderline personality disorder (BPD) is a highly comorbid disorder, and these comorbidities increase the impairment associated with BPD. For example, depression, which occurs in the majority of individuals with BPD, increases the likelihood of an individual with BPD to engage in nonsuicidal self-injury (NSSI). Little research, however, has investigated potential mechanisms of NSSI engagement in this population. The current study aimed to fill this gap by examining momentary experiences, levels of distress tolerance, and NSSI among 51 individuals meeting current diagnostic criteria for BPD and a comorbid depressive disorder. Using data from an ecological momentary assessment across 7 days, it was found that daily urges to hurt oneself and impulsive urges, but not daily negative affect or aggressive urges, predicted NSSI occurrence. Furthermore, low levels of distress tolerance was a stronger predictor of NSSI behavior than daily experiences. These findings have important implications with regard to state versus trait dispositions in NSSI engagement among those with BPD and depression.

Brain activation in response to overt and covert fear and happy faces in women with borderline personality disorder

Borderline personality disorder (BPD) is a serious condition involving emotion dysregulation. Past research has identified BPD-associated differences within fronto-limbic circuitry during conditions of processing negative emotion. Functional magnetic resonance imaging (fMRI) paradigms that incorporate overt and covert (masked) presentations of emotional stimuli can provide complementary information about neural systems underlying emotion processing (e.g., both slow [overt] and fast [covert; automatic] processing pathways). This study examined brain activation during processing of overt and covert presentations of emotional faces in 12 women with BPD and 12 age-matched healthy controls. To assess a range of emotional valence and arousal, we examined responses to fear, happy and neutral expressions. All participants underwent an fMRI scanning session in which participants passively viewed emotional faces. Scanning sessions consisted of 5 runs including: (1) Overt Fear (OF) versus Neutral (N), (2) Covert Fear (CF) versus Covert Neutral (CN), (3) Overt Happy (OH) versus N, (4) Covert Happy (CH) versus CN, and (5) N versus fixation. We compared whole-brain activation between groups for each run. In response to overt fear, BPD patients showed greater activation both in left amygdala and in several frontal cortical regions. There were no significant differences in brain activation in response to overt happy faces. In response to covert fear and covert happy stimuli, the BPD group also showed greater activation than controls in several regions including frontal and temporal cortical regions, as well as cerebellum and thalamus. These findings add to prior reports suggesting increased amygdala activation in BPD, but we found this only in the overt fear versus fixation condition. In this sample, BPD patients showed hyper-activation, rather than hypo-activation, of cortical regulatory regions during overt fear. Enhanced cortical recruitment in response to covert fear and happy faces in BPD could reflect a more extended response system in which stimuli that typically only activate automatic pathways are additionally tapping into cortical regulatory systems. The observation of this pattern both in response to fear and in response to happy presentations suggests that the effect of arousal may be as or more impactful than the effect of emotional valence.

Genetic and environmental influences on the codevelopment among borderline personality disorder traits, major depression symptoms, and substance use disorder symptoms from adolescence to young adulthood

Although borderline personality disorder (BPD) traits decline from adolescence to adulthood, comorbid psychopathology such as symptoms of major depressive disorder (MDD), alcohol use disorder (AUD), and drug use disorders (DUDs) likely disrupt this normative decline. Using a longitudinal sample of female twins (N = 1,763), we examined if levels of BPD traits were correlated with changes in MDD, AUD, and DUD symptoms from ages 14 to 24. A parallel process biometric latent growth model examined the contributions of genetic and environmental factors to the relationships between developmental components of these phenotypes. Higher BPD trait levels predicted a greater rate of increase in AUD and DUD symptoms, and higher AUD and DUD symptoms predicted a slower rate of decline of BPD traits from ages 14 to 24. Common genetic influences accounted for the associations between BPD traits and each disorder, as well as the interrelationships of AUD and DUD symptoms. Both genetic and nonshared environmental influences accounted for the correlated levels between BPD traits and MDD symptoms, but solely environmental influences accounted for the correlated changes between the two over time. Results indicate that higher levels of BPD traits may contribute to an earlier onset and faster escalation of AUD and DUD symptoms, and substance use problems slow the normative decline in BPD traits. Overall, our data suggests that primarily genetic influences contribute to the comorbidity between BPD features and substance use disorder symptoms. We discuss our data in the context of two major theories of developmental psychopathology and comorbidity.

The Still-Face: A Greater Challenge for Infants of Mothers With Borderline Personality Disorder

The main aim of this study was to ascertain whether infants as young as 3 months of age, whose mothers suffer from borderline personality disorder (BPD), are already at risk of greater dysregulation than infants of mothers without BPD when faced with a minor stressful experience. Nineteen mothers diagnosed with BPD and 41 controls with no history of psychopathology and their 3-month-old infants were observed using Tronick's Face-to-Face Still-Face paradigm. The authors found that infants whose mothers have BPD express less positive vocalizations and less nonautonomic self-regulation than infants of mothers with no psychopathology. The stress of the Still-Face episode affects their gaze and self-regulation behaviors more strongly than those of infants of controls. The Reunion episode seems particularly challenging for mothers with BPD, who show fewer smiles and an increase in intrusive behavior. Because infants and their mothers with BPD are already dysregulated at 3 months postpartum, envisaging very early intervention seems warranted.

Personality Factors and Depressive Configurations. An Exploratory Study in an Italian Clinical Sample

Introduction: This study focuses on the relationship between personality configurations and depressive experiences. More specifically, the aim of this study is to investigate the relationship between self-criticism and dependency and personality styles or disorders, exploring the association between personality features and depressive symptoms. The two-configurations model of personality developed by Blatt (2004, 2008) is adopted as a reference point in sharing a valid framework and in understanding the results.

Methods: Five instruments are administered to 51 participants with a diagnosis of depressive disorder, in accordance with DSM-IV-TR (American Psychiatric Association, 2000): Self-criticism and dependency dimensions of depression are measured with the Depressive Experiences Questionnaire (DEQ); self-reported depression is assessed with the Beck Depression Inventory-II (BDI-II); observer-rated depression is assessed with the Hamilton Depression Rating Scale (HDRS); personality is assessed with the Clinical Diagnostic Interview (CDI) and the Shedler Westen Assessment Procedure-200 (SWAP-200).

Results: Only self-criticism, and not dependency, is associated with depressive symptoms. In addition, the SWAP Borderline PD Scale and the Dysphoric: Emotionally dysregulated Q-factor emerge as significant in predicting depression.

Conclusions: Findings support the assumption that depressive personality configurations can enhance the vulnerability to developing depression. Theoretical and clinical implications of these results are discussed.

The prevalence, age distribution and comorbidity of personality disorders in Australian women

OBJECTIVE

We aimed to describe the prevalence and age distribution of personality disorders and their comorbidity with other psychiatric disorders in an age-stratified sample of Australian women aged ⩾25 years.

METHODS

Individual personality disorders (paranoid, schizoid, schizotypal, histrionic, narcissistic, borderline, antisocial, avoidant, dependent, obsessive-compulsive), lifetime mood, anxiety, eating and substance misuse disorders were diagnosed utilising validated semi-structured clinical interviews (Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Research Version, Non-patient Edition and Structured Clinical Interview for DSM-IV Axis II Personality Disorders). The prevalence of personality disorders and Clusters were determined from the study population ( n = 768), and standardised to the Australian population using the 2011 Australian Bureau of Statistics census data. Prevalence by age and the association with mood, anxiety, eating and substance misuse disorders was also examined.

RESULTS

The overall prevalence of personality disorders in women was 21.8% (95% confidence interval [CI]: 18.7, 24.9). Cluster C personality disorders (17.5%, 95% CI: 16.0, 18.9) were more common than Cluster A (5.3%, 95% CI: 3.5, 7.0) and Cluster B personality disorders (3.2%, 95% CI: 1.8, 4.6). Of the individual personality disorders, obsessive-compulsive (10.3%, 95% CI: 8.0, 12.6), avoidant (9.3%, 95% CI: 7.1, 11.5), paranoid (3.9%, 95% CI: 3.1, 4.7) and borderline (2.7%, 95% CI: 1.4, 4.0) were among the most prevalent. The prevalence of other personality disorders was low (⩽1.7%). Being younger (25-34 years) was predictive of having any personality disorder (odds ratio: 2.36, 95% CI: 1.18, 4.74), as was being middle-aged (odds ratio: 2.41, 95% CI: 1.23, 4.72). Among the strongest predictors of having any personality disorder was having a lifetime history of psychiatric disorders (odds ratio: 4.29, 95% CI: 2.90, 6.33). Mood and anxiety disorders were the most common comorbid lifetime psychiatric disorders.

CONCLUSIONS

Approximately one in five women was identified with a personality disorder, emphasising that personality disorders are relatively common in the population. A more thorough understanding of the distribution of personality disorders and psychiatric comorbidity in the general population is crucial to assist allocation of health care resources to individuals living with these disorders.

The impact of borderline personality disorder and sub-threshold borderline personality disorder on the course of self-reported and clinician-rated depression in self-harming adolescents

BACKGROUND

Studies on adults suggest that the presence of comorbid depression and Borderline Personality Disorder (BPD) is associated with an elevated risk of self-harming behaviours and that self-harming behaviours, when present, will have higher severity. This comorbidity, furthermore, complicates clinical assessments, which may be an obstacle to early identification and proper intervention. Adolescents who self-harm frequently report high levels of depressive symptoms, but this is often not reflected in the clinicians' assessment. BPD is still a controversial diagnosis in young people, and less is known about the clinical significance of comorbid BPD in adolescent populations.The purpose of the present study was to examine the impact of BPD on the assessment and course of self-reported and clinician-rated depression in self-harming adolescents before and after a treatment period of 19 weeks. We hypothesized that, compared to adolescents without BPD, adolescents with BPD would self-report higher levels of depression at baseline, and that they would have less reduction in depressive symptoms.

METHODS

A total of 39 adolescents with depressive disorders and BPD-traits participating in a randomised controlled trial on treatment of self-harm with Dialectical Behaviour Therapy adapted for Adolescents or enhanced usual care were included. Adolescents with full-syndrome BPD (n = 10) were compared with adolescents with sub-threshold BPD (n = 29) with respect to their self-reported and clinician-rated depressive symptoms, suicidal ideation and global level of functioning at baseline, and after 19 weeks of treatment (end of trial period).

RESULTS

At baseline, adolescents with full-syndrome BPD self-reported significantly higher levels of depressive symptoms and suicidal ideation compared to adolescents with sub-threshold BPD, whereas the two groups were rated as equally depressed by the clinicians. At trial completion, all participants had a significant reduction in suicidal ideation, however, adolescents with BPD had a poorer treatment outcome in terms of significantly higher levels of clinician-rated and self-reported depressive symptoms and significantly lower levels of global functioning. At baseline as well as at trial completion, self-reported and clinician-rated levels of depressive symptoms were not significantly correlated in adolescents with BPD. In a multiple linear regression analysis, a diagnosis of BPD and a high baseline level of clinician-rated depressive symptoms predicted higher levels of depressive symptoms at trial completion, whereas receiving Dialectical Behaviour Therapy predicted lower levels of depressive symptoms.

CONCLUSION

Our findings suggest that a diagnosis of BPD may have a strong impact on the assessment and course of depressive symptoms in self-harming adolescents. Although rated as equally depressed, adolescents with BPD self-reported significantly higher levels of depressive symptoms and suicidal ideation at baseline, and showed a poorer outcome in terms of higher levels of depressive symptoms and lower levels of global functioning at trial completion compared to adolescents with sub-threshold BPD. Our findings suggest that receiving Dialectical Behaviour Therapy could lead to a greater reduction in depressive symptoms, although firm conclusions cannot be drawn given the limited sample size.Clinicians should be aware of the possibility of underestimating the severity of depression in the context of emotional and behavioral dysregulation. Providing BPD specific treatments seems to be important to achieve sufficient treatment response with regard to depressive symptoms in adolescents with BPD-traits.

Integrating Early Intervention for Borderline Personality Disorder and Mood Disorders

Borderline personality disorder (BPD) has been demonstrated to be a reliable and valid construct in young people (adolescents and young adults). Both borderline- and mood-related psychopathology become clinically apparent from puberty through to young adulthood, frequently co-occur, can reinforce one another, and can be difficult to differentiate clinically. This Gordian knot of overlapping clinical features, common risk factors, and precursors to both BPD and mood disorders complicates clinical assessment, prevention, and treatment. Regardless of whether an individual crosses an arbitrary diagnostic threshold, a considerable proportion of young people with borderline- and mood-related psychopathology will develop significant and persistent functional, vocational, and interpersonal impairment and disability during this critical risk and developmental period. There is a clear need for early intervention, but spurious diagnostic certainty risks stigma, misapplication of diagnostic labels, inappropriate treatment, and unfavorable outcomes. This article aims to integrate early intervention for BPD and mood disorders in the clinical context of developmental and phenomenological change and evolution. "Clinical staging," similar to disease staging in general medicine, is presented as a pragmatic, heuristic, and trans-diagnostic framework to guide prevention and intervention. It acknowledges that the early stages of these disorders cannot be disentangled sufficiently to allow for disorder-specific preventive measures and early interventions. Clinical staging defines an individual's location along the continuum of the evolving temporal course of a disorder. Such staging aids differentiation of early or milder clinical phenomena from those that accompany illness progression and chronicity, and suggests the application of appropriate and proportionate intervention strategies.

Borderline personality features in depressed or anxious patients

Anxiety and depression frequently co-occur with borderline personality disorder. Relatively little research examined the presence of borderline personality features and its main domains (affective instability, identity problems, negative relationships and self-harm) in individuals with remitted and current anxiety and depression. Participants with current (n=597) or remitted (n=1115) anxiety and/or depression and healthy controls (n=431) were selected from the Netherlands Study of Depression and Anxiety. Assessments included the Personality Assessment Inventory - Borderline Features Scale and several clinical characteristics of anxiety and depression. Borderline personality features were more common in depression than in anxiety. Current comorbid anxiety and depression was associated with most borderline personality features. Anxiety and depression status explained 29.7% of the variance in borderline personality features and 3.8% (self-harm) to 31% (identity problems) of the variance in the four domains. A large part of the variance was shared between anxiety and depression but both disorders also explained a significant amount of unique variance. The severity of anxiety and depression and the level of daily dysfunctioning was positively associated with borderline personality features. Individuals with a longer duration of anxiety and depression showed more affective instability and identity problems. These findings suggest that patients with anxiety and depression may benefit from an assessment of personality pathology as it may have implications for psychological and pharmacological treatment.

The Application of an Etiological Model of Personality Disorders to Problem Gambling

Problem gambling is a significant mental health problem that creates a multitude of intrapersonal, interpersonal, and social difficulties. Recent empirical evidence suggests that personality disorders, and in particular borderline personality disorder (BPD), are commonly co-morbid with problem gambling. Despite this finding there has been very little research examining overlapping factors between these two disorders. The aim of this review is to summarise the literature exploring the relationship between problem gambling and personality disorders. The co-morbidity of personality disorders, particularly BPD, is reviewed and the characteristics of problem gamblers with co-morbid personality disorders are explored. An etiological model from the more advanced BPD literature-the biosocial developmental model of BPD-is used to review the similarities between problem gambling and BPD across four domains: early parent-child interactions, emotion regulation, co-morbid psychopathology and negative outcomes. It was concluded that personality disorders, in particular BPD are commonly co-morbid among problem gamblers and the presence of a personality disorder complicates the clinical picture. Furthermore BPD and problem gambling share similarities across the biosocial developmental model of BPD. Therefore clinicians working with problem gamblers should incorporate routine screening for personality disorders and pay careful attention to the therapeutic alliance, client motivations and therapeutic boundaries. Furthermore adjustments to therapy structure, goals and outcomes may be required. Directions for future research include further research into the applicability of the biosocial developmental model of BPD to problem gambling.

PATHOLOGICAL PERSONALITY TRAITS AND THE NATURALISTIC COURSE OF INTERNALIZING DISORDERS AMONG HIGH-RISK YOUNG ADULTS

BACKGROUND

A personality disorder diagnosis signals a negative prognosis for depressive and anxiety disorders, but the precise abnormal personality traits that determine the temporal course of internalizing psychopathology are unknown. In the present study, we examined prospective associations between abnormal personality traits and the onset and recurrence of internalizing disorders.

METHODS

A sample of 371 young adults at high risk for internalizing problems completed the Schedule for Nonadaptive and Adaptive Personality-Second Edition--a measure of 12 abnormal personality traits and three temperament dimensions (i.e., Negative Temperament, Positive Temperament, Disinhibition vs. Control)--and underwent annual diagnostic interviews over 4 years of follow-up.

RESULTS

In multivariate survival analyses, Negative Temperament was a robust predictor of both new onsets and recurrences of internalizing disorder. Further, the Dependency and Self-Harm abnormal personality dimensions emerged as independent predictors of new onsets and recurrences, respectively, of internalizing disorders after statistically adjusting for variation in temperament.

CONCLUSIONS

Our findings suggest that abnormal personality traits and temperament dimensions have complementary effects on the trajectory of internalizing pathology during young adulthood. In assessment and treatment settings, targeting the abnormal personality and temperament dimensions with the greatest prognostic value stands to improve the early detection of enduring internalizing psychopathology.

Reduced neural differentiation between self-referential cognitive and emotional processes in women with borderline personality disorder

Borderline personality disorder (BPD) is associated with disturbed emotion regulation. Psychotherapeutic interventions using mindfulness elements have shown effectiveness in reducing clinical symptoms, yet little is known about their underlying neurobiology. In this functional magnetic resonance imaging (fMRI) study, 19 female BPD patients and 19 healthy controls were compared during mindful introspection, cognitive self-reflection and a neutral condition. The activation pattern in the right dorsomedial prefrontal cortex (DMPFC) in BPD patients was different from that in healthy subject when directing attention onto their emotions and bodily feelings in contrast to cognitively thinking about themselves. Mindful introspection compared with the neutral condition was associated with higher activations in bilateral motor/pre-motor regions, left inferior frontal gyrus (IFG), and left posterior cingulate cortex (PCC), while cognitive self-reflection activated the right motor and somatosensory cortex, extending into the right supramarginal gyrus (SMG) and superior temporal gyrus (STG) in BPD patients compared with the controls. Results indicate that self-referential cognitive and emotional processes are not clearly differentiated in BPD patients at the neurobiological level. In particular, altered neural mechanism underlying self-referential thinking may be related to some aspects of the typical emotion dysregulation in BPD. Current data support the finding that mindful self-focused attention is effective in regulating amygdala activity in BPD as well as in healthy subjects.

The impact of comorbid personality difficulties on response to IAPT treatment for depression and anxiety

The UK's Improving Access to Psychological Therapies (IAPT) initiative provides evidence-based psychological interventions for mild to moderate common mental health problems in a primary care setting. Predictors of treatment response are unclear. This study examined the impact of personality disorder status on outcome in a large IAPT service. We hypothesised that the presence of probable personality disorder would adversely affect treatment response.

METHOD

We used a prospective cohort design to study a consecutive sample of individuals (n = 1249).

RESULTS

Higher scores on a screening measure for personality disorder were associated with poorer outcome on measures of depression, anxiety and social functioning, and reduced recovery rates at the end of treatment. These associations were not confounded by demographic status, initial symptom severity nor number of treatment sessions. The presence of personality difficulties independently predicted reduced absolute change on all outcome measures.

CONCLUSIONS

The presence of co-morbid personality difficulties adversely affects treatment outcome among individuals attending for treatment in an IAPT service. There is a need to routinely assess for the presence of personality difficulties on all individuals referred to IAPT services. This information will provide important prognostic data and could lead to the provision of more effective, personalised treatment in IAPT.

Are personality disorder dimensions related over time? An examination over the course of ten years using multivariate growth modeling

OBJECTIVE

Despite the well-documented literature on cross-sectional comorbidity, there is a paucity of data on the associations between personality disorders (PDs) over time. Using multivariate growth modeling, the present study examined the inter-relationships between pairs of PD disorder dimensions.

METHODS

We tested these associations in a sample of 142 depressed outpatients followed-up five times over the course of 10 years.

RESULTS

We found cross-sectional associations between the initial levels of severity of many pairs of PD dimensions. However, there was limited support for longitudinal associations between PD dimensions.

CONCLUSION

These findings suggest that the course of PD dimensions is fairly independent of each other, and that initial levels of PD dimensions have relatively little prognostic value for predicting the course of other PD dimensions.

Personality disorders and the persistence of substance use disorders: A reanalysis of published NESARC findings

The purpose of this study was to examine whether published findings regarding the association of personality disorders (PDs) with the persistence of substance use disorders (SUDs) are attributable to an artifact due to time of assessment of the PD. Two previous studies analyzed data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and found that Antisocial PD, Schizotypal PD, and Borderline PD are unique predictors of SUDs. However, a design limitation in NESARC (assessment of PDs at different waves) can potentially compromise these findings. To assess the influence of time of assessment of PDs and to identify associations that might be robust to time of assessment, we compared the association of PDs with 2 estimates of SUD persistence that were based on different populations at risk: (a) among those who were diagnosed with SUD at baseline, the proportion who continued to meet full criteria at follow-up ("prediction"); and (b) among those who were diagnosed with SUD at follow-up, the proportion who met full criteria at baseline ("postdiction"). Differences between prediction and postdiction revealed a robust pattern of higher odds ratios for postdiction among PDs assessed at baseline, and lower odds ratios for postdiction among PDs assessed at follow-up. All published significant associations between PDs and persistence of SUDs became nonsignificant in the postdiction analyses, with the exception of obsessive-compulsive PD predicting nicotine dependence persistence. The present results raise serious doubts about the validity of published findings on PDs and SUD persistence from the NESARC. Design limitations in NESARC preclude a direct comparison among PDs measured at different waves.

Passive event-related potentials to a single tone in treatment-resistant depression, generalized anxiety disorder, and borderline personality disorder patients

PURPOSE

Treatment-resistant depression is comorbid with personality or anxiety disorder; how passive attention functions in these disorders remains unknown. A single tone-elicited event-related potential P3 component (passive P3) might help to characterize the passive attention in these disorders.

METHODS

The passive P3 test was applied to 32 patients with treatment-resistant depression, 35 with generalized anxiety disorder, and 21 with borderline personality disorder, as well as to 31 healthy volunteers. The Zung Self-rating Depression and Anxiety Scales were used to measure the respective depression and anxiety levels in these participants.

RESULTS

All patients scored significantly higher on depression and anxiety than the healthy participants did. P3 amplitude was significantly reduced in groups with treatment-resistant depression and generalized anxiety disorder but not in the group with borderline personality disorder or healthy controls. Anxiety level was negatively correlated with P3 amplitude in healthy controls rather than in other groups.

CONCLUSIONS

This study did not discriminate treatment-resistant depression and generalized anxiety disorder regarding the passive P3 but suggested that there was a generalized impairment of passive attention in these disorders.

Depression in patients with borderline personality disorder

Borderline personality disorder (BPD) and major depressive disorder (MDD) commonly co-occur, but the relationship between these disorders remains unclear. While BPD patients often suffer from depression, their subjective experience and treatment response are different from that experienced by MDD patients without BPD. Surveying the current literature on the interface of these two pathologies, we find that depression in BPD has distinct symptoms, treatment responses, remission predictors, and suicide risks. It tends to be subjectively more severe, more interpersonally fueled, and more persistent than MDD without BPD. BPD depression responds less well to biological treatments and may be fueled by the neurobiology of BPD. These findings suggest that clinicians should recognize the unique features of BPD depression and anticipate a clinical trajectory that may be different from MDD without BPD, keeping in mind that BPD depression tends not to improve until BPD improves.

Altered emotion processing circuits during the anticipation of emotional stimuli in women with borderline personality disorder

Borderline personality disorder (BPD) is associated with disturbed emotion processing, typically encompassing intense and fast emotional reactions toward affective stimuli. In this study, we were interested in whether emotional dysregulation in BPD occurs not only during the perception of emotional stimuli, but also during the anticipation of upcoming emotional pictures in the absence of concrete stimuli. Eighteen female patients with a diagnosis of BPD and 18 healthy control subjects anticipated cued visual stimuli with prior known emotional valence or prior unknown emotional content during functional magnetic resonance imaging. Brain activity during the anticipation of emotional stimuli was compared between both groups. When anticipating negative pictures, BPD patients demonstrated less signal change in the left dorsal anterior cingulate cortex (dACC) and left middle cingulate cortex (MCC), and enhanced activations in the left pregenual ACC, left posterior cingulate cortex (PCC) as well as in left visual cortical areas including the lingual gyrus. During the anticipation of ambiguously announced stimuli, brain activity in BPD was also reduced in the left MCC extending into the medial and bilateral dorsolateral prefrontal cortex. Results point out that deficient recruitment of brain areas related to cognitive-emotional interaction already during the anticipation phase may add to emotional dysregulation in BPD. Stronger activation of the PCC could correspond to an increased autobiographical reference in BPD. Moreover, increased preparatory visual activity during negative anticipation may contribute to hypersensitivity toward emotional cues in this disorder.

Large variation of severity and longitudinal change of symptom distress among patients with personality disorders

Main objectives were to investigate (1) the longitudinal course of symptom distress among patients with personality disorders (PD) and (2) how different Axis-I and Axis-II pathology and treatment factors predict or moderate long-term outcome. All patients (n = 751) were admitted to short-term day hospital treatment, and 47% continued in group psychotherapy (mean duration 2.3 years). Symptom distress was assessed repeatedly over 5 years (Symptom Check List 90-R). Mixed models were chosen for statistical analyses. A main finding was the large variation in severity and longitudinal course of symptom distress. Five-year trends ranged from full symptom remission (31%) to pervasive, severe distress (36%). Co-occurring Axis-I disorders did not explain longitudinal variability of symptom distress. However, the presence and increasing severity of Axis-II pathology was strongly associated with more severe baseline symptom distress. Poor long-term outcomes were associated with the combination of avoidant PD and long treatment durations (>2.5 years), and borderline PD and short treatment durations (<0.4 years). Contrastingly, considerable symptom relief was associated with borderline PD and long treatment duration. In conclusion, the severity and longitudinal course of symptom distress among PD patients is closely associated with their personality structures and not sufficiently explained by Axis-I comorbidity.

Identifying personality pathology associated with major depressive episodes: incremental validity of informant reports

Major limitations are associated with the use of a single source of information to assess personality pathology. The construct validity of standardized interviews and informant reports on personality pathology has been established relative to other measures of personality pathology, but it is also important to consider these measures in relation to other constructs that should be related to personality pathology. One example is major depression. In this study, we evaluated whether less common clinical methods of assessment for measuring the same personality pathology constructs, including semistructured interviews and informant reports, demonstrate unique validity, using major depressive episode (MDE) as the external criterion. This analysis focuses on a representative, community-based sample of 1,437 participants and informants. We conducted a hierarchical logistic regression analysis and determined the order of entering the predictor variables based on likelihood of being used in a clinical setting as well as empirical recommendations. Each step of our regression model significantly increased our ability to predict lifetime MDE, including self, interviewer, and informant reports of personality pathology. Overall, these findings indicate that multiple sources of personality assessment provide unique information about the relationship between maladaptive personality traits and a history of MDE. Thus, semistructured diagnostic interviews and informant reports can be used as a resource to improve the validity of personality assessments.

The relationship between borderline personality disorder and major depression in later life: acute versus temperamental symptoms

OBJECTIVE

A recent issue in the personality disorder field is the prevalence and course of Axis II symptoms in later life. Focusing on the presentation of personality disorder criteria over time may have some utility in exploring the relationship between borderline personality disorder (BPD) and major depression in older adults. Temperamental personality symptoms are relatively resistant to change but tend to be nonspecific to disorders, whereas acute symptoms remit relatively quickly. We predicted that temperamental BPD symptoms would be positively correlated with a history of depression and did not expect to find a relationship between major depression and acute BPD symptoms.

METHODS

A total of 1,630 participants between the ages of 55 and 64 were recruited to participate in a community-based longitudinal study representative of the St. Louis area. Participants completed a battery of assessments at baseline, including diagnostic interviews for all 10 personality disorders and major depressive disorder.

RESULTS

Temperamental and acute BPD symptoms were significantly correlated with a history of major depression. After adjustments were made for the effects of temperamental symptoms on depression, acute symptoms were no longer correlated with a history of depression. As predicted, temperamental symptoms remained significantly related to depression, even after controlling for the effects of acute symptoms. BPD acute symptoms showed a unique negative correlation with the amount of time following remission from a depressive episode.

CONCLUSIONS

Overall, this study supports associations between major depression and borderline personality in older adults. The findings indicate that a history of major depression is primarily related to stable BPD symptoms related to emotional distress, which are more prevalent in older adults than acute features.

Amygdala functional connectivity in young women with borderline personality disorder

Borderline personality disorder (BPD) is a complex psychiatric disorder that involves the core feature of affect dysregulation. Prior neuroimaging studies have indicated that BPD patients have (1) excessive amygdala activation to negative emotion and (2) diminished frontal regulation. This study examined amygdala functional connectivity in 12 women with BPD and 12 matched healthy comparison volunteers. We explored how connectivity patterns would change in the context of processing neutral, overt fear, or masked fear face expressions. Each participant underwent three 5-min fMRI scans in which they primarily viewed: (1) neutral, (2) overt fear, and (3) masked fear faces. In comparison to their healthy counterparts, young women with BPD showed (1) lower connectivity between bilateral amygdala and mid-cingulate cortex during the neutral scan; (2) higher connectivity between bilateral amygdala and rostral anterior cingulate cortex during the overt fear scan; and (3) higher right amygdala connectivity with bilateral thalamus and right caudate during the masked fear scan. Exploratory analyses revealed interesting correlations between amygdala connectivity in these conditions with multiple clinical measures. Results from the neutral scan add to the few prior connectivity studies in BPD that have been suggestive of lower fronto-limbic connectivity in BPD. However, the connectivity findings during fear processing are novel, and map onto basic research models for amygdala connectivity, that is, connections to frontal areas for overt fear processing versus connections to thalamus for automatic fear processing. Further, results suggest that BPD subjects tap into both pathways more strongly than healthy comparisons.
