Developmental Trajectories of Borderline Personality Disorder Symptoms and Psychosocial Functioning in Adolescence

Symptom domains and psychosocial functioning in borderline personality disorder

BACKGROUND

Borderline personality disorder (BPD) is often characterized by severe functional impairment, even after a decrease in symptoms. A comprehensive understanding of psychosocial functioning in BPD is necessary to tailor treatment offer, which should address relevant aspects of daily life. The aims of the present study are to (1) conduct a cross-sectional comparison of functioning of a group with BPD and a non-BPD clinical comparison group at service entry, and to (2) assess the relationship between intensity of BPD symptom domains and psychosocial functioning.

METHODS

The sample consists of N = 65 participants with BPD and N = 57 participants from the clinical comparison group without BPD (non-BPD group). The Revised Borderline Follow-up Interview (BFI-R) was used to evaluate psychosocial functioning and the Revised Diagnostic Interview for Borderlines (DIB-R) to assess BPD symptoms. Linear, logistic, and multinomial regression models were run separately for each aspect of functioning as a function of BPD status or BPD symptom domains.

RESULTS

Only 23% of participants in the BPD group fulfilled criteria for good overall psychosocial functioning, compared to 53% in the non-BPD group. Furthermore, participants in the BPD group were less likely to have completed a high number of years of education, to work consistently, to be financially independent, to be in a cohabiting relationship and have a good relationship with parents. In addition, various links were identified between BPD symptom domains and functional impairments.

CONCLUSIONS

Consistent with prior research, the main impairments in functioning in the BPD group are found in the educational and vocational domains. Though some domains show impairment, others, like friendships, may act as potential resources. Further investigation on the relationships with symptom domains is required.

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.

The impact of a combined mentalisation-based therapy and therapeutic community programme for adolescents with borderline personality disorder traits on service utilisation in Western Australia

This study assessed the effect of a mentalisation-based therapy (MBT) treatment programme on the utilisation of Western Australian public hospitals for mental health presentations over an 18-month period. Hospital data included the number of visits to the emergency department (ED), the number of inpatient admissions to hospital and length of stay of the admissions. Participants included 76 adolescents aged 13-17 years old, who presented with borderline personality disorder (BPD) traits. The Touchstone treatment programme is a time-limited intensive programme that utilises MBT in the context of a therapeutic community. Hospital data for the participants were collected and analysed from three time points; 6 months prior to attending the programme, during the 6-month programme (active treatment) and 6 months after the programme. Results found a statistically significant decrease in hospital utilisation from pre to post programme, with a decline in ED visits, inpatient admissions and admission length of stay. This study presents promising preliminary evidence for the effectiveness of an intensive MBT programme as an intervention for adolescents with BPD features and has significant implications for the public health system in terms of providing effective community-based treatment for this difficult to treat population as well as reducing pressure on tertiary care.

Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18): Factor Structure, Validity, and Clinical Cut-Offs

The Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18) is the only self-report measure informed by the Level of Personality Functioning (Diagnostic and Statistical Manual of Mental Disorders [5th ed.; DSM-5; American Psychiatric Association, 2013]) Alternative Model of Personality Disorders developed for adolescents. The present investigation includes two studies evaluating the English LoPF-Q 12-18. In Study 1, single-factor and bifactor structures (unidimensional severity criterion and four specific factors: identity, self-direction, empathy, intimacy) were evaluated in an ethnically diverse community sample (N = 453; age 10-18; 57% female). Study 2 used a community control (n = 298; age 10-18; 54.4% female) and clinical sample (n = 94; age 11-18; 58.5% female) to examine reliability, validity, and clinical utility. Study 1 results supported the bifactor model, with a robust general factor and little multidimensionality caused by the group factors, suggesting an essentially unidimensional structure. Study 2 revealed good internal consistency and construct validity and provided clinical cut-offs, supporting the use of the LoPF-Q 12-18 total score in research and clinical applications.

Motor synchronization and impulsivity in pediatric borderline personality disorder with and without attention-deficit hyperactivity disorder: an eye-tracking study of saccade, blink and pupil behavior

Shifting motor actions from reflexively reacting to an environmental stimulus to predicting it allows for smooth synchronization of behavior with the outside world. This shift relies on the identification of patterns within the stimulus - knowing when a stimulus is predictable and when it is not - and launching motor actions accordingly. Failure to identify predictable stimuli results in movement delays whereas failure to recognize unpredictable stimuli results in early movements with incomplete information that can result in errors. Here we used a metronome task, combined with video-based eye-tracking, to quantify temporal predictive learning and performance to regularly paced visual targets at 5 different interstimulus intervals (ISIs). We compared these results to the random task where the timing of the target was randomized at each target step. We completed these tasks in female pediatric psychiatry patients (age range: 11-18 years) with borderline personality disorder (BPD) symptoms, with (n = 22) and without (n = 23) a comorbid attention-deficit hyperactivity disorder (ADHD) diagnosis, against controls (n = 35). Compared to controls, BPD and ADHD/BPD cohorts showed no differences in their predictive saccade performance to metronome targets, however, when targets were random ADHD/BPD participants made significantly more anticipatory saccades (i.e., guesses of target arrival). The ADHD/BPD group also significantly increased their blink rate and pupil size when initiating movements to predictable versus unpredictable targets, likely a reflection of increased neural effort for motor synchronization. BPD and ADHD/BPD groups showed increased sympathetic tone evidenced by larger pupil sizes than controls. Together, these results support normal temporal motor prediction in BPD with and without ADHD, reduced response inhibition in BPD with comorbid ADHD, and increased pupil sizes in BPD patients. Further these results emphasize the importance of controlling for comorbid ADHD when querying BPD pathology.

Developmental trajectories of anger and sadness dysregulation in childhood differentially predict later borderline symptoms

Difficulties with emotion regulation are integral to borderline personality disorder (BPD) and its hypothesized developmental pathway. Here, we prospectively assess trajectories of emotion processing across childhood, how BPD symptoms impact these trajectories, and whether developmental changes are transdiagnostic or specific to BPD, as major depressive (MDD) and conduct disorders (CD) are also characterized by emotion regulation difficulties. This study included 187 children enriched for those with early symptoms of depression and disruptive behaviors from a longitudinal study. We created multilevel models of multiple components of emotional processing from mean ages 9.05 to 18.55 years, and assessed the effect of late adolescent BPD, MDD, and CD symptoms on these trajectories. Linear trajectories of coping with sadness and anger, and quadratic trajectories of dysregulated expressions of sadness and anger were transdiagnostic, but also exhibited independent relationships with BPD symptoms. Only inhibition of sadness was related to BPD symptoms. The quadratic trajectories of poor emotional awareness and emotional reluctance were also independently related to BPD. Findings support examining separable components of emotion processing across development as potential precursors to BPD, underscoring the importance of understanding these trajectories as not only a marker of potential risk but also potential targets for prevention and intervention.

Maternal postnatal depression and anxiety and the risk for mental health disorders in adolescent offspring: Findings from the Avon Longitudinal Study of Parents and Children cohort

OBJECTIVE

The impacts of postnatal psychiatric disorders on different types of mental health problems in offspring are unclear. We investigated the prospective associations of maternal postnatal depression, and anxiety, with offspring depression, anxiety, psychotic-like experiences and Borderline Personality Disorder symptoms, in adolescence, and examined whether these were independent of each other.

METHODS

Data were obtained from the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort. Maternal postnatal depression and anxiety at 8 weeks were measured using the Edinburgh Postnatal Depression Scale and Crown-Crisp Index, respectively. Offspring mental health outcomes were measured at 10-13 years old, using a variety of questionnaire-based and interview assessments. Logistic regression analyses were used to assess the associations between maternal postnatal risk factors and offspring mental health, and path analysis was used to investigate the pathways of maternal postnatal factors to adolescent offspring outcomes.

RESULTS

Data were available for 14,054 mothers with information reported on postnatal depression and 13,892 on postnatal anxiety. Logistic regression analyses found significant associations between maternal postnatal depression and offspring anxiety at 10 years old (odds ratio = 1.039, 95% confidence interval = [1.005, 1.073], p = 0.022) and between maternal postnatal anxiety and offspring psychotic experiences at 12/13 years old (odds ratio = 1.042, 95% confidence interval = [1.008, 1.077], p = 0.016). These significant associations remained after applying path analyses, when we controlled for potential offspring psychopathological overlay.

CONCLUSION

These findings suggest that mothers with postnatal depression are more likely to have offspring with anxiety at 10 years old, and that mothers with postnatal anxiety are more likely to have offspring with psychotic experiences at 12/13 years old. Our findings suggest specific pathways in the association between postnatal anxiety/depression and offspring mental health and contribute to the importance of identifying mothers and their offspring with increased vulnerability to adverse outcomes resulting from postnatal mental health disorders.

Frontal EEG asymmetry moderates the relation between borderline personality disorder features and feelings of social rejection in adolescents

Although associations among borderline personality disorder (BPD), social rejection, and frontal EEG alpha asymmetry scores (FAA, a neural correlate of emotion regulation and approach-withdrawal motivations) have been explored in different studies, relatively little work has examined these relations during adolescence in the same study. We examined whether FAA moderated the relation between BPD features and rejection sensitivity following a validated social exclusion paradigm, Cyberball. A mixed, clinical-community sample of 64 adolescents (females = 62.5%; Mage = 14.45 years; SD = 1.6; range = 11-17 years) completed psychodiagnostic interviews and a self-report measure of BPD (Time 1). Approximately two weeks later (Time 2), participants completed a resting EEG recording followed by Cyberball. FAA moderated the relation between BPD features and overall feelings of rejection following Cyberball: individuals with greater relative left FAA had the highest and lowest feelings of social rejection depending on whether they had high and low BPD feature scores, respectively. Results remained after controlling for age, sex, gender, depression, and BPD diagnosis. These results suggest that FAA may moderate the relation between BPD features and social rejection, and that left frontal brain activity at rest may be differentially associated with those feelings in BPD. Findings are discussed in terms of the link between left frontal brain activity in the regulation and dysregulation of social approach behaviors, characteristic of BPD.

Characteristics and Predictors of Educational and Occupational Disengagement Among Outpatient Youth With Borderline Personality Disorder

This study aimed to investigate predictors of vocational disengagement (referred to as Not in Employment, Education, or Training [NEET]) in young people with borderline personality disorder (BPD). The sample comprised 112 outpatients with a BPD diagnosis, aged 15-25 years, who participated in a randomized controlled trial (ANZCTR12610000100099). The proportion of participants who were NEET (39.3%) at study entry did not improve after 18 months and NEET status frequently changed. Therefore, multinomial regression analyses were used to study three groups: Non-NEET, NEET, and Unstable NEET status. NEET status was predicted by not achieving expected age-appropriate educational milestones, greater instability in identity, and emptiness. Greater instability in interpersonal relationships and identity predicted Unstable NEET status. The findings suggest that specific vocational interventions, that also incorporate a focus on interpersonal functioning, emptiness, and identity disturbance, are needed to improve functioning in youth with BPD, especially when educational milestones are not achieved.

Borderline personality disorder in young people: associations with support and negative interactions in relationships with mothers and a best friend

BACKGROUND

Impaired interpersonal functioning has been highlighted as a core feature of borderline personality disorder (BPD). Adolescence and young adulthood form important developmental stages within both the emergence of BPD and the development of interpersonal functioning, which takes place mostly in relationships with parents and friends. This study aimed to: (i) investigate relations between BPD symptoms and both supportive and negative interactions with mothers and best friends; (ii) investigate whether the relations were moderated by age; (iii) test the robustness of our findings by comparing the results based on self-reports with results from a subsample in which supportive and negative interactions with mothers were rated by the mother.

METHODS

312 young people referred to mental healthcare completed self-report measures on BPD and supportive and negative interactions. Multiple regression analyses were conducted to examine the relations between BPD features and perceived supportive and negative interactions with mothers and a best friend, and to investigate whether these relations were moderated by age. Robustness of our findings was studied in a subsample (n = 104), by using a multi-informant design in maternal report on supportive and negative interactions with mothers.

RESULTS

Multiple regression analyses demonstrated that negative interactions with mothers as well as with a best friend were related to more BPD symptoms in young people. Supportive interactions were not related to BPD symptoms. Both BPD and quality of relations were not related to age. In a subsample in which supportive and negative interactions with mothers were rated by the mother, the maternal report showed slightly different results. In this model, both supportive and negative interactions with a best friend were positively related, whereas interactions with mothers were not related to BPD symptoms in young people.

CONCLUSIONS

Results highlight the importance of relationships with mothers and a best friend during adolescence and young adulthood. Given that BPD often emerges during this developmental phase, future research is needed to clarify how quality of relationships could alter pathways toward BPD in young people.

Change in the Definition of Personality Disorder in Transition to ICD-11: A Look from Clinical and Developmental Perspectives

The recent body of research reveals fundamental limitations to the categorical concept of a personality disorder that has led researchers to adopt a new personality disorder concept. During the last decade DSM-5 and ICD-11 diagnostic classifications have accepted the dimensional view towards personality pathology. Despite the differences between the two classifications, the joint aspect of both models is the construct of Levels of personality functioning. The construct of personality functioning involves personality (dys)function in the self and interpersonal domains. This two-step conceptualization includes (a) impairments of self and interpersonal functioning, indicating general signs and severity of personality disorder, and (b) pathological personality traits, reflecting ‘stylistic’ differences in the expression of personality disorder. The new conceptualization of personality disorder reflects the innovative multi-theoretical integration of known, empirically-based personality assessment paradigms. The relationship between personality functioning and interpersonal, psychodynamic, and personological paradigms provides the theoretical integrity and empirically-based structure necessary to understand the overall severity of personality pathology. Many methods (interviews, self-assessment scales, and questionnaires) have already been developed for the assessment of personality functioning, and their development will be encouraged by the ICD-11 classification established in 2022. At present, only one instrument has been developed in Lithuania for assessing the level of personality functioning in young people aged 12–18 (Barkauskienė & Skabeikytė, 2020). The empirical data about the validity of this construct and its capability to differentiate between the normal and impaired personality in adults and adolescents provide promising results, but are still accumulating. Research suggests that adolescence is a stage in development when personality pathology can fully unfold and be validly confirmed, which opens up opportunities for early intervention. Although the dimensional personality disorder model needs to further prove its importance, there is already evidence that it is less stigmatizing and returns psychology and personality into the concept of a personality disorder. This review presents changes in the conceptualization of personality disorders by discussing them from both clinical and developmental perspectives and highlighting the results of key research in recent years.

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

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

A systematic review of the factors associated with the course of borderline personality disorder symptoms in adolescence

BACKGROUND

Research on personality pathology in adolescence has accelerated during the last decade. Among all of the personality disorders, there is strong support for the validity of borderline personality disorder (BPD) diagnosis in adolescence with comparable stability as seen in adulthood. Researchers have put much effort in the analysis of the developmental pathways and etiology of the disorder and currently are relocating their attention to the identification of the possible risk factors associated with the course of BPD symptoms during adolescence. The risk profile provided in previous systematic reviews did not address the possible development and course of BPD features across time. Having this in mind, the purpose of this systematic review is to identify the factors that are associated with the course of BPD symptoms during adolescence.

METHODS

Electronic databases were systematically searched for prospective longitudinal studies with at least two assessments of BPD as an outcome of the examined risk factors. A total number of 14 articles from the period of almost 40 years were identified as fitting the eligibility criteria.

CONCLUSIONS

Factors associated with the course of BPD symptoms include childhood temperament, comorbid psychopathology, and current interpersonal experiences. The current review adds up to the knowledge base about factors that are associated with the persistence or worsening of BPD symptoms in adolescence, describing the factors congruent to different developmental periods.

The Course of Borderline Psychopathology in Adolescents with Complex Mental Health Problems: An 18 Month Longitudinal Follow-up Study

A persistent and significant barrier to the diagnosis and treatment of borderline personality disorder (BPD) in adolescents is clinician reluctance to label an adolescent with a stigmatized, intractable, treatment-resistant diagnosis. The goal of the current study was to evaluate this claim by examining the 18-month longitudinal course of borderline pathology in adolescents after discharge from inpatient treatment. 556 adolescent consecutive admissions (64.6% female; ages 12-17, M = 15.29, SD = 1.46) were assessed during admission to an inpatient treatment facility. They were followed up at discharge, 6 months, 12 months and 18 months after discharge with validated self-and parent report measures of adolescent BPD features. Latent growth modeling was used to evaluate outcomes. BPD features showed a significant decline over the follow-up period with very large effect sizes (> .80) for both parent and adolescent self-report. Rates of change were steeper for adolescent report although adolescent report fell below clinical cut-off 6 months later than parent-report. However, when internalizing and externalizing psychopathology were included in latent growth models, youth-reported BPD features did not show the same level of decline, while parent-reported BPD features maintained the same level of decline. The rate of decline between parents and adolescents was correlated, and baseline levels of BPD features were predictive of rate of change. This is the first study to show that adolescent borderline pathology follows a similar course after discharge from inpatient treatment previously demonstrated for adults. Like adult BPD, adolescent BPD appears to be not as intractable and treatment resistant as previously thought, mitigating against therapeutic nihilism.

An Evaluation of Age-Group Latent Mean Differences in Maladaptive Identity in Adolescence

Little is known about the differences between age groups in maladaptive personality function as denoted in Criterion A of the Alternative Model for Personality Disorder (AMPD) in the DSM-5, which is the entry criterion for diagnosing personality disorder in the upcoming ICD-11. The current study aimed to address this gap by evaluating latent mean age group differences in maladaptive identity, which is one aspect that has been identified as an important feature of maladaptive, general personality function as represented in the DSM-5 and ICD-11. We were also interested whether mean differences would track with mean differences in borderline personality disorder (BPD) features given prior data suggesting that general personality function overlap with the construct of BPD. A community sample of N = 2,381 adolescents, representing a mix of different socio-economic and educational backgrounds, ages 12-18 (M = 14.92, SD = 1.94; 46% male) completed a measure of maladaptive identity. A subset (n = 1,165) completed a measure of borderline personality features. Latent variable modeling was used to evaluate latent mean differences across seven age bands. Results suggested a normative increase in maladaptive identity after age 12, which remained consistent until age 17 when it dropped back to levels observed in 12-year-olds. Maladaptive identity was significantly associated with mean-level increases in borderline personality features, with these constructs becoming more closely associated with increasing age.

Number of Borderline Personality Disorder Criteria and Depression Predict Poor Functioning and Quality of Life in Outpatient Youth

This study aimed to investigate which factors contribute to poor functioning and poor quality of life in youth (aged 15-25 years) with borderline personality disorder (BPD), and whether the number of BPD criteria might be an independent predictor of these outcomes. A sample of 499 help-seeking outpatient youth, aged 15-25 years, was assessed. Stepwise multiple regression analyses showed that the number of BPD criteria was the best predictor of poor functioning, followed by number of mental health visits in the past month, female sex, and a current diagnosis of depression. Current depression was the best predictor of Assessment of Quality of Life utility score, followed by the number of BPD criteria. These findings underscore the clinical significance of DSM-IV BPD features (even when subthreshold for a categorical diagnosis) in youth and their effects upon social and occupational functioning and quality of life early in the course of BPD.

Association of Parent-Reported Sleep Problems in Early Childhood With Psychotic and Borderline Personality Disorder Symptoms in Adolescence

IMPORTANCE

Persistent nightmares in childhood have been prospectively associated with psychosis and borderline personality disorder (BPD) in adolescence. However, the extent to which this association is also true for behavioral sleep problems is still unknown, and the potential mechanisms are unexplored.

OBJECTIVE

To examine the prospective associations between several parent-reported sleep problems in early childhood and psychotic and BPD symptoms at 11 to 13 years of age and the potential mediation of the associations by depression at 10 years of age.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study assessed 13 488 participants in the Avon Longitudinal Study of Parents and Children birth cohort who were followed up for more than 13 years. Pregnant women from Avon, United Kingdom, with expected dates of delivery from April 1, 1991, to December 31, 1992, were invited to take part in the study. Data analysis was conducted from May 1 to December 31, 2019.

MAIN OUTCOMES AND MEASURES

Psychotic experiences at 12 to 13 years of age were assessed using the Psychosis-Like Symptom Interview, and BPD symptoms at 11 to 12 years of age were tested using the UK Childhood Interview for DSM-IV Borderline Personality Disorder. Parent-reported nighttime sleep duration, night awakening frequency, bedtime, and regularity of sleep routines were assessed when the child was 6, 18, and 30 months and 3.5, 4.8, and 5.8 years of age.

RESULTS

Data were available on 7155 participants (3718 girls [52%]) who reported on BPD symptoms and 6333 (3280 boys [52%]) who reported on BPD symptoms. Higher night awakening frequency at 18 months of age (odds ratio [OR], 1.13; 95% CI, 1.01-1.26) and less regular sleep routines at 6 months (OR, 0.68; 95% CI, 0.50-0.93), 30 months (OR, 0.64; 95% CI, 0.44-0.95), and 5.8 years (OR, 0.32; 95% CI, 0.19-0.53) of age were significantly associated with psychotic experiences in adolescence, whereas shorter nighttime sleep duration (OR, 0.78; 95% CI, 0.66-0.92) and later bedtime at 3.5 years of age (OR, 1.32; 95% CI, 1.09-1.60) were significantly associated with BPD symptoms. Results of mediation analysis were consistent with all these associations, except for later bedtime at 3.5 years and BPD in adolescence, which had no association. Depression at 10 years of age mediated the associations between frequent night awakenings at 18 months of age (bias-corrected estimate, -0.005; 95% CI, -0.008 to -0.002; P = .002) and irregular sleep routines at 5.8 years of age (bias-corrected estimate, -0.006; 95% CI, -0.010 to -0.003; P = .003) with psychosis.

CONCLUSIONS AND RELEVANCE

The findings suggest that some behavioral sleep problems in childhood are distinctively associated with the onset of psychosis and BPD in adolescence, following different pathways. Furthermore, depression at 10 years of age may mediate only the association with psychosis. These findings contribute to the design of more personalized interventions in psychosis and BPD.

Too Much Too Soon?: Borderline Personality Disorder Symptoms and Romantic Relationships in Adolescent Girls

Despite the centrality of adult romantic relationships to the conceptualization of borderline personality disorder (BPD), little is known about the earlier development of this interdependency during adolescence. Thus, we examined the co-development of romantic relationships and BPD symptoms from ages 15 to 19 in a large urban sample of girls (N = 2310) in the Pittsburgh Girls Study. We had two major aims. First, we sought to examine associations between BPD symptoms and romantic relationship involvement (number of partners, importance of relationship) and relational insecurity (concerns about infidelity and tactics to maintain relationship) during adolescence. Second, we investigated mutual influences and temporal precedence of BPD symptoms and four specific romantic relationship characteristics (perceived support and antagonism, verbal and physical aggression) during adolescence using latent growth curve models (LGCMs). Results indicated that BPD symptoms were associated with increased involvement in romantic relationships and heightened relational insecurity across adolescence. Furthermore, higher BPD symptoms at age 15 predicted increases in antagonism, verbal aggression, and physical aggression across ages 15 to 19. Conversely, perceptions of higher levels of relationship support at age 15 predicted steeper increases in BPD symptoms across ages 15 to 19, suggesting a potential negative influence of early involvement in close romantic relationships. These findings demonstrate the reciprocal nature of romantic relationship functioning and BPD symptoms during adolescence and suggest novel prevention targets for youth at risk for BPD.

Borderline personality disorder: course and outcomes across the lifespan

This article presents an overview of the current literature on the course and outcomes of BPD. It begins with an overview of our changing understanding of BPD in terms of age of onset and prognosis over time. Recent research on clinical, functional and social recovery from BPD in youth and adult populations is then summarised. This is followed by an overview of contemporary prospective studies of adolescent BPD in community populations which seek to unravel complex pathways and the co-development of BPD symptoms and psychosocial problems. Studies of older populations are then described to shed light on how BPD manifests in middle to old age. The review concludes by bringing together these research strands to develop a picture of BPD across the lifespan and highlight areas for future research.

Developmental Trajectories of Adolescent Girls' Borderline Personality Symptoms and Sexual Risk Behaviors

Adolescence is a developmental period during which youth tend to initiate sexual behavior, which may include sexual risk behavior. Symptoms of borderline personality disorder (BPD) are associated with increased rates of risky behaviors. However, little is known about longitudinal associations between BPD symptoms and sexual risk behaviors during adolescence. This study examines developmental trajectories of adolescent girls' BPD symptoms and sexual risk behaviors in a community sample of Black and White girls from the Pittsburgh Girls Study (n = 1620). Dual trajectory modeling provided insights into the temporal precedence and co-development of BPD symptoms and sexual risk behaviors from ages 14 to 18. In order to examine the unique association between BPD symptoms and sexual risk behaviors, analyses controlled for symptoms of depression and conduct disorder, as well as race, sexual orientation, and pubertal development. Girls with more BPD symptoms at age 14 showed steeper growth over time in sexual risk behaviors from ages 14 to 18. Additionally, adolescents who showed steeper increases in BPD symptoms over time also showed steeper increases in sexual risk behaviors across adolescence. Notably, however, sexual risk behavior at age 14 was not significantly associated with longitudinal trajectories of BPD symptoms. Results suggest that adolescent girls with early symptoms of BPD are at heightened risk for the development of sexual risk behaviors during adolescence, while the reverse association does not hold. Implications for adolescent development and sexual risk behavior are discussed.

Barriers to care for adolescents with borderline personality disorder

Intervention for borderline personality disorder (BPD) in adolescence is crucial as early onset of the disorder predicts more severe course, and intervention 'late' in the course of the disorder is associated with more negative outcomes. In spite of this, access to services is poor. This is because several unique barriers to accessing care exist for adolescents with BPD. In this article we highlight key barriers to care for adolescents with BPD utilizing a conceptual model for understanding health care access that emphasizes the interaction between patient and health care system characteristics. We conclude with proposed recommendations to address these identified barriers.

INdividual Vocational and Educational Support Trial (INVEST) for young people with borderline personality disorder: study protocol for a randomised controlled trial

Background

The clinical onset of borderline personality disorder (BPD) usually occurs in young people (aged 12–25 years) and commonly leads to difficulty achieving and maintaining vocational (education and/or employment) engagement. While current psychosocial interventions lead to improvements in psychopathology, they have little effect upon functioning. Individual Placement and Support (IPS) is a client-driven model that assists individuals with severe mental illness to engage with education and/or employment appropriate to their personal goals, and that provides ongoing support to maintain this engagement. The objective of the INdividual Vocational and Educational Support Trial (INVEST) is to evaluate the effectiveness of adding IPS to an evidence-based early intervention programme for BPD, with the aim of improving vocational outcomes.

Methods/design

INVEST is a single-blind, parallel-groups, randomised controlled trial (RCT). The randomisation is stratified by gender and age and uses random permuted blocks. The interventions are 39 weeks of either IPS, or ‘usual vocational services’ (UVS). Participants will comprise 108 help-seeking young people (aged 15–25 years) with three or more DSM-5 BPD features and a desire to study or work, recruited from the Helping Young People Early (HYPE) early intervention programme for BPD at Orygen, in Melbourne, Australia. All participants will receive the HYPE intervention. After baseline assessment, staff who are blind to the intervention group allocation will conduct assessments at 13, 26, 39 and 52 weeks. At the 52-week primary endpoint, the primary outcome is the number of days in mainstream education/employment since baseline. Secondary outcomes include the cost-effectiveness of the intervention, quality of life, and BPD severity.

Discussion

Current treatments for BPD have little impact on vocational outcomes and enduring functional impairment is prevalent among this patient group. IPS is a targeted functional intervention, which has proven effective in improving vocational outcomes for adults and young people with psychotic disorders. This trial will investigate whether IPS is effective for improving vocational (employment and educational) outcomes among young people with subthreshold or full-syndrome BPD.

Development and Validation of the Interview of Personality Organization Processes in Adolescence (IPOP-A)

The assessment of personality and personality pathology in adolescence represents a critical topic to understand adolescent's difficulties, predict long-term outcome in adulthood, and indicate adequate treatment. Personality Organization, and its underlying dimensions, plays an essential role in shaping how adolescents face their developmental tasks as they are connected with psychosocial functioning and psychopathological severity. However, few measures are available to assess personality organization during adolescence. The aim of the present research is to investigate the psychometric properties of the Interview of Personality Organization Processes in Adolescence (IPOP-A), a semi-structured interview designed for the assessment of the main personality organization dimensions in adolescence. Three studies were performed to explore the psychometric properties of the IPOP-A, in terms of factor structure, reliability, convergent, and discriminant validity. Exploratory and confirmatory factor analysis supported the IPOP-A construct validity. Furthermore, IPOP-A showed good reliability and evidenced a convergent and discriminant validity with DSM-oriented personality patterns, emotion dysregulation, identity disturbance, and psychopathology. Our results provide evidence of IPOP-A validity to assess emerging personality organization in adolescence. Furthermore, the IPOP-A is a promising tool to use in the clinical consultation and treatment planning for the adolescent.

Outcome of depressive mood disorder among adolescent outpatients in an eight-year follow-up

OBJECTIVES

This study investigated the eight-year course and outcomes of depressive mood disorders and the key outcome predictors among adolescent outpatients.

METHODS

Depressive adolescent outpatients (N = 148) in a naturalistic clinical setting were assessed at baseline, six months, 12 months and eight years using diagnostic and self-report instruments. Baseline predictors covered selected sociodemographic, clinical and treatment-related characteristics. The outcomes were time to recovery, recurrence, time spent being ill and longitudinal latent profiles of depressive symptoms.

RESULTS

The recovery rate from any depressive mood disorder was 73% at two years, 91% at five years and 94% by the end of the eight-year follow-up. Two thirds (67%) of the subjects presented at least one recurrence and 57% of them were depressed for 25% or more of the follow-up period. At the eight-year follow-up, 36% had a mood disorder, 48% suffered from anxiety and 26% had a personality disorder. Less severe depression at baseline predicted a shorter time to recovery, whereas recurrence was predicted by a younger age. A latent profile with initially moderate-level depressive symptoms but a poor distal outcome was associated with being female and borderline personality disorder.

LIMITATIONS

The female preponderance in the sample warrants caution when interpreting sex differences in the findings.

CONCLUSIONS

Although the depression outcome for some adolescents making the transition to young adulthood is promising, many of them experience long, even chronic episodes, and recurrences are common. Personality-disorder characteristics appeared to be significant outcome predictors in this adolescent population.

Designing a range of mentalizing interventions for young people using a clinical staging approach to borderline pathology

Borderline personality disorder (BPD) can have a long-lasting impact on social and professional functioning, even when core symptoms of BPD are in remission. Adolescence may be a critical developmental period to change the potential long-term functional outcome of BPD. This paper presents a range of mentalizing interventions to alter the course and outcome of BPD, based upon a model of clinical staging. Mentalizing interventions have in common a focus on strengthening self-regulatory and interpersonal capacities, aiming to improve adaptive social learning. This paper argues that these interventions should be dosed and organized according to the stage of progression of BPD, which is illustrated by discussing different specific formats for mentalization-based interventions, including an early-intervention program for BPD and a standard program for full BPD.

Dating violence victimization and borderline personality pathology: Temporal associations from late adolescence to early adulthood

Borderline personality pathology is a serious mental illness characterized by pervasive interpersonal deficits that onset during adolescence. Risk factors for borderline personality pathology include maladaptive interpersonal dynamics within attachment relationships. Given the shift toward emphasizing romantic relationships during adolescence as an important attachment relationship with implications for healthy development, the current study aimed to evaluate the longitudinal and reciprocal relations between victimization in dating relationships and borderline pathology in the transition from late adolescence to early adulthood. A large sample of high school daters (N = 818; 58% female; Mage = 16.10 years, SDage = .78) were recruited to complete annual assessments of borderline personality features and dating violence victimization across 5 years. Results of a cross-lagged panel model revealed that primarily among girls, borderline features predicted increased levels of relational, psychological, and physical violence, whereas psychological and sexual violence predicted greater borderline features. The current findings provide the first evidence of a longitudinal association between victimization and borderline pathology in adolescence and suggest, particularly among girls, that interventions for borderline features have important implications for reducing dating violence victimization among adolescents and young adults.

Borderline Personality Features Scale for Children-11: Measurement invariance over time and across gender in a community sample of adolescents

The Borderline Personality Features Scale for Children (BPFS-C) was recently shortened using item response theory to an 11-item version that is optimal for use in epidemiological studies and repeated assessment over time. Only 1 study has examined invariance of the BPFS-C-11 items across gender and no study has done so over time. The present study employed a longitudinal design to address this gap by evaluating measurement invariance across gender and over time during the transition into adulthood in a diverse community-based sample of 755 adolescents (56% female). Results indicated measurement variance for items measuring personal relationships and impulsivity/recklessness, with females having a greater probability of endorsing items regarding relationship instability and males more likely to endorse impulsivity, despite an equal position on the latent trait. Overall, there was partial measurement invariance of a single dimension of borderline features between males and females and full longitudinal invariance of this factor through the transition into young adulthood. The current findings provide empirical evidence supporting the reliability of BPFS-C-11 scores as a measure of borderline pathology (BP) during late adolescence and early adulthood.

Psychotherapy for Borderline Personality Disorder in Adolescents

Research on borderline personality disorder (BPD) in adolescence has helped to clarify the characteristics of BPD in young people. The considerable emotional and economic cost associated with adolescent BPD supports calls for early intervention and requires that the assessment of personality functioning be an essential component in the psychological evaluation of adolescents. Adult treatment models with demonstrated efficacy have been adapted for adolescents. This article describes the implementation of these treatment approaches, factors that frequently complicate the recognition and diagnosis of BPD in young people, and an overview of research on BPD in adolescents that delineates its clinically relevant features.

A Neuroscience-Oriented Research Approach to Borderline Personality Disorder

Traditionally, the study of personality disorders had been based on psychoanalytic or behavioral models. Over the past two decades, there has been an emerging neuroscience model of borderline personality disorder (BPD) grounded in the concept of BPD as a condition in which dysfunctional neural circuits underlie its pathological dimensions, some of which include emotion dysregulation (broadly encompassing affective instability, negative affectivity, and hyperarousal), abnormal interpersonal functioning, and impulsive aggression. This article, initiated at a joint Columbia University- Cornell University Think Tank on BPD with representation from the Icahn School of Medicine at Mount Sinai, suggests how to advance research in BPD by studying the dimensions that underlie BPD in addition to studying the disorder as a unitary diagnostic entity. We suggest that linking the underlying neurobiological abnormalities to behavioral symptoms of the disorder can inform a research agenda to better understand BPD with its multiple presentations.

Adolescence as a Sensitive Period for the Development of Personality Disorder

Over the last 15 years, controversy over the construct of adolescent personality disorder has largely been laid to rest because of accumulating empirical evidence in support of its construct validity. In this article, four conclusions that can be drawn from recent literature on borderline disorder in adolescents are discussed, with the ultimate goal of building an argument to support the idea that adolescence is a sensitive period for the development of personality disorder.

Borderline personality disorder is equally trait-like and state-like over ten years in adult psychiatric patients

Borderline personality disorder (PD) has historically been cast as an unabating condition. Longitudinal data, however, support a more variable time course marked by remission and relapse. In the present study, we tested the possibility that borderline PD has both stable (i.e., consistently present across time and situation, as modern diagnostic systems stipulate) and dynamic (i.e., episodic and situational) elements. Participants were 668 patients from the Collaborative Longitudinal Personality Disorders Study who were administered semistructured diagnostic interviews 5 times over a decade. Trait-state-occasion modeling dissected borderline pathology into time-invariant (i.e., trait) and time-varying (i.e., state) components. Contradicting traditional views of PD intransigence, less than half of borderline PD variability (approximately 45%) was time-invariant (i.e., perfectly stable) over the study timeframe. Furthermore, we found that the time-invariant component of borderline pathology, which we termed borderline proneness, was very closely related (r = .81) to a previously validated Five Factor Model trait composite of borderline features. Moreover, the trait versus state components showed a clear pattern of discriminant validity in relation to several putative causal agents for borderline PD (i.e., environmental pathogens, temperament dimensions). We conclude that borderline pathology contains a stable core and sizable situational components, and that both elements relate systematically to normative personality dimensions and known risk factors. These findings have key implications for etiological research, prognosis, and treatment for borderline PD. (PsycINFO Database Record

Borderline personality disorder

Caretakers are often intimidated or alienated by patients with borderline personality disorder (BPD), compounding the clinical challenges posed by the severe morbidity, high social costs and substantial prevalence of this disorder in many health-care settings. BPD is found in ∼1.7% of the general population but in 15-28% of patients in psychiatric clinics or hospitals and in a large proportion of individuals seeking help for psychological problems in general health facilities. BPD is characterized by extreme sensitivity to perceived interpersonal slights, an unstable sense of self, intense and volatile emotionality and impulsive behaviours that are often self-destructive. Most patients gradually enter symptomatic remission, and their rate of remission can be accelerated by evidence-based psychosocial treatments. Although self-harming behaviours and proneness to crisis can decrease over time, the natural course and otherwise effective treatments of BPD usually leave many patients with persistent and severe social disabilities related to depression or self-harming behaviours. Thus, clinicians need to actively enquire about the central issues of interpersonal relations and unstable identity. Failure to correctly diagnose patients with BPD leads to misleading pharmacological interventions that rarely succeed. Whether the definition of BPD should change is under debate that is linked to not fully knowing the nature of this disorder.

Psychosocial functioning in adolescents with and without borderline personality disorder

OBJECTIVE

Little is known about the psychosocial functioning of adolescents with borderline personality disorder (BPD). The main objective of this paper is to compare the psychosocial functioning of a group of adolescents with BPD to a group of psychiatrically healthy adolescents.

METHODS

The present cross-sectional study included 104 adolescent inpatients with BPD, compared with 60 age-matched psychiatrically healthy comparison subjects. All participants were rigorously diagnosed using three semi-structured interviews: the Structured Clinical Interview for DSM-IV Childhood Diagnoses, the Revised Diagnostic Interview for Borderlines and the Childhood Interview for DSM-IV Borderline Personality. All subjects were also interviewed using the adolescent version of the Background Information Schedule to assess multiple facets of psychosocial functioning.

RESULTS

Adolescents with BPD rated their relationships with their parents as significantly less positive, were more likely to date, but spent more time alone than their healthy counterparts. In addition, adolescents with BPD reported significantly more problems at work and school (i.e. lower frequency of having a good work or school history, higher frequency of being suspended or expelled from school) and significantly lower rates of participation in extra-curricular activities than their healthy counterparts.

CONCLUSIONS

Taken together, the results of this study suggest that adolescents with BPD are more impaired in both the social and vocational areas of functioning than psychiatrically healthy comparison subjects. They might also suggest that an overlooked area of strength concerns their relationships with peers. Copyright © 2017 John Wiley & Sons, Ltd.

Seven-Year Course of Borderline Personality Disorder Features: Borderline Pathology Is as Unstable as Depression during Adolescence

Borderline personality disorder (PD) historically is construed as an unremitting condition with poor prognosis. The present study takes a new approach to examining stability and change in borderline PD by explaining symptom expression in terms of an unchanging foundation-termed borderline proneness-on one hand, and transitory influences on the other. We monitored borderline PD symptoms annually in a large sample of high-risk adolescent girls (N = 2,450) from ages 14 to 20. Trait-state-occasion modeling revealed that just over half (52-57%) of borderline PD symptom variation was attributable to fixed borderline proneness, whereas the remainder was subject to change across yearly measurement occasions. This degree of stability was no larger than the corresponding estimate for depression, a condition known for its variable course. Our results indicate that, contrary to its reputation, borderline pathology is not set in stone, and it fluctuates in response to situational influences.

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.

Self-reported patterns of impairments in mentalization, attachment, and psychopathology among clinically referred adolescents with and without borderline personality pathology

BACKGROUND

Previous research, which primarily focused on adult samples, suggests that individuals with borderline personality disorder (BPD) display high levels of psychopathology, dysfunctional mentalization and problematic attachment to others. The current study investigated whether impairments in mentalization, attachment, and psychopathology are more severe in outpatient adolescents with BPD than in a clinical comparison group.

METHODS

Consecutive referrals to a child and adolescent psychiatric clinic were clinically assessed with a battery of self-report instruments to assess mentalization, attachment, and psychopathology. Specifically, in regard to BPD a self-report questionnaire was employed to decide if patients were classified into the BPD or the clinical comparison group. The main outcome variables of adolescents with a primary diagnosis of BPD were then compared with those of a clinical comparison group comprising patients receiving psychiatric diagnoses other than BPD.

RESULTS

Relative to the clinical group without BPD, and after controlling for sociodemographic variables, the BPD group displayed poorer mentalizing abilities, more problematic attachments to parents and peers, and higher self-reported levels of psychopathology.

CONCLUSIONS

The results of this study suggest that BPD is a severe mental condition in adolescents and is characterized by poor mentalizing abilities, attachment problems and high levels of psychopathology compared to adolescents with psychiatric disorders other than BPD. Hence, clinicians should consider BPD when conducting diagnostic assessments, and evidence-based treatments for this vulnerable group should be developed.

Pupillary and affective responses to maternal feedback and the development of borderline personality disorder symptoms

Etiological models propose that a biological vulnerability to emotional reactivity plays an important role in the development of borderline personality disorder (BPD). However, the physiological and phenomenological components of emotional reactivity that predict the course of BPD symptoms in adolescence are poorly understood. This prospective study examines pupillary and affective responses to maternal feedback as predictors of BPD symptom development in adolescent girls over 18 months. Fifty-seven 16-year-old girls completed a laboratory task in which they heard recorded clips of their own mothers making critical or praising statements about them, as well as neutral statements that did not pertain to them. Changes in girls' pupil dilation and subjective affect were assessed throughout the task. The results demonstrated that greater pupillary response to maternal criticism predicted increases in BPD symptoms over time. In addition, greater pupillary and positive affective responses to maternal praise were associated with higher BPD symptoms at age 16 and faster decreases in BPD symptoms over time, but only among girls who heard clips that were rated by independent observers as less praising. The results suggest that emotional reactivity can serve as either a risk or a protective factor depending on context, with differential effects of reactivity to criticism versus praise.

Characterizing emotional dysfunction in borderline personality, major depression, and their co-occurrence

This research aimed to characterize patterns of emotional reactivity and dysregulation in borderline personality, depression, and their co-occurrence. In study 1, 488 young adult women from the community were categorized into four groups based on self-reported major depressive disorder (MDD) and borderline personality disorder (BPD) symptoms (Low BPD/Low MDD; Low BPD/High MDD; High BPD/Low MDD; High BPD/High MDD). Immediate and prolonged subjective emotional reactivity to a laboratory stressor were assessed, and participants completed self-report and behavioral measures of emotion dysregulation. Study 2 extended these findings, examining emotional reactivity and dysregulation in a clinical population of 176 substance dependent patients with diagnoses of BPD and MDD and including a biological index of emotional reactivity. Results revealed greater prolonged fear reactivity in the High BPD/High MDD (vs. Low BPD/Low MDD) group in study 1, and greater prolonged anxiety and negative affect reactivity in both High BPD groups (vs. Low BPD/Low MDD and Low BPD/High MDD groups) in study 2 (but no differences in cortisol reactivity). Results also demonstrated greater subjective (but not behavioral) emotion dysregulation in the High BPD/High MDD (vs. Low BPD/Low MDD) group in study 1 and both High BPD groups (vs. both Low BPD groups) in study 2. Finally, the High BPD/High MDD group reported greater difficulties controlling impulsive behaviors compared with all other groups in study 1 and the Low BPD groups in study 2. Findings suggest that BPD pathology (but not MDD pathology alone) is characterized by greater prolonged emotional (especially anxiety/fear-related) reactivity and heightened emotion dysregulation.

The Main and Interactive Effects of Maternal Interpersonal Emotion Regulation and Negative Affect on Adolescent Girls' Borderline Personality Disorder Symptoms

The transaction of adolescent's expressed negative affect and parental interpersonal emotion regulation are theoretically implicated in the development of borderline personality disorder (BPD). Although problem solving and support/validation are interpersonal strategies that foster emotion regulation, little is known about whether these strategies are associated with less BPD severity among adolescents. Adolescent girls (age 16; N = 74) and their mothers completed a conflict discussion task, and maternal problem solving, support/validation, and girls' negative affect were coded. Girls' BPD symptoms were assessed at four time points. A 3-way interaction of girls' negative affect, problem solving, and support/validation indicated that girls' negative affect was only associated with BPD severity in the context of low maternal support/validation and high maternal problem solving. These variables did not predict changes in BPD symptoms over time. Although high negative affect is a risk for BPD severity in adolescent girls, maternal interpersonal emotion regulation strategies moderate this link. Whereas maternal problem solving coupled with low support/validation is associated with a stronger negative affect-BPD relation, maternal problem solving paired with high support/validation is associated with an attenuated relationship.

Personality disorders and violence: what is the link?

Despite a well-documented association between personality disorders (PDs) and violence, the relationship between them is complicated by the high comorbidity of mental disorders, the heterogeneity of violence (particularly in regard to its motivation), and differing views regarding the way PDs are conceptualised and measured. In particular, it remains unclear whether there is a causal relationship between PDs and violence, and what the psychological mechanisms might be that mediate such a relationship. Here, a perspective on PD and violence is offered that views the relationship between them through the lenses of the Five Factor Model of personality and a quadripartite typology of violence. Evidence is reviewed suggesting that emotion dysregulation/impulsiveness, psychopathy, and delusional ideation conjointly contribute to the increased risk of violence shown by people with PD, and do so by contributing to a broad severity dimension of personality dysfunction. This view is consistent with the abandonment of personality disorder categories in the forthcoming eleventh edition of the International Classification of Diseases (ICD-11), where severity of personality disorder is defined in terms of the degree of harm to self and others.
