Two-year stability of personality disorder in older adolescent outpatients

Risk-taking and self-harm behaviors as markers of adolescent borderline personality disorder

Adolescence is a critical period for early identification and intervention of borderline personality disorder (BPD). Risk-taking and self-harm behaviors (RSB) have been identified as promising early markers of BPD and correlates of depression in school-based samples. The present study aimed, first, to examine the association between RSB and BPD in a clinical sample of adolescents and, second, to examine whether RSB are also linked to depression. N = 405 participants (82.7% female) were recruited from an outpatient clinic for adolescents with RSB. RSB assessed included truancy, excessive media use, alcohol, tobacco, and illicit drug use, sexual risk-taking, and self-harm behavior. Regression analyses and generalized linear models were performed to examine the associations between individual RSB or patterns of RSB (identified using latent class analysis, LCA) and a diagnosis and severity of BPD or depression. All RSB (except excessive media use) were positively associated with BPD diagnosis and severity. In contrast, only non-suicidal self-injury (NSSI) and suicide attempts were positively associated with depression diagnosis and severity, while illicit drug use was negatively associated with depression severity. The LCA yielded two classes differing in the occurrence of RSB. The high RSB class was more likely to have a BPD diagnosis and greater BPD severity than the low RSB class. Classes did not differ regarding depression diagnosis or severity. As NSSI and suicide attempts were associated with both BPD and depression, the presence of additional RSB, besides self-harm behavior, may represent a specific risk marker for BPD in adolescents.

Bidirectional relationship between borderline personality features and depressive symptoms in early adolescence: A school-based cohort study

Depressive symptoms is a public health concern worldwide, and adolescents may experience more depressive symptoms. Although the relationship between borderline personality features (BPFs) disorder and depressive symptoms has been established, it is unclear whether the longitudinal relationship between them is unidirectional or bidirectional and whether these symptoms are different between boys and girls. In this study, Chinese adolescents (1608 total and separately 972 for boys and 636 girls) were enrolled between September 2019 and September 2021, and we analyzed the data using a cross-lagged model. The results suggested a bidirectional relationship between BPFs and depressive symptoms in boys (β = 0.191 and 0.117, P < 0.001). However, in girls, depressive symptoms were predicted based on BPFs (β = 0.225, P < 0.001), whereas BPFs were not predicted based on depressive symptoms (β = 0.035, P = 0.535). The findings suggest that borderline personality traits and depressive symptoms are only bilaterally associated in girls, which also provides important evidence for the treatment and prevention of adolescent BPFs and depressive symptoms.

One-year prevalence and psychiatric comorbidity of borderline personality disorder in a medical certificate population: a registry study of psychiatric outpatients in community mental health care in the city of Oulu

OBJECTIVE

Borderline personality disorder (BPD) is a common disorder in healthcare settings but estimates of BPD prevalence vary greatly. This study aimed to estimate the one-year prevalence of BPD in psychiatric outpatients and analyze the psychiatric comorbidity presented with BPD.

METHOD

The data comprised 18-60-year-old patients who had a BPD diagnosis recorded in their medical certificate B (mcB) and were treated in specialized psychiatric outpatient services in the city of Oulu, northern Finland, in 2014. An mcB is a comprehensive summary of a patient's medical history written by a doctor, and patients need it in the Finnish healthcare system when applying for social benefits and rehabilitation measures.

RESULTS

The prevalence of BPD was 12.8% among patients with an mcB treated in the psychiatric outpatient services. BPD was 3.0 times more common in female than male psychiatric outpatients with an mcB. The most common comorbid psychiatric disorders written in mcBs of BPD patients were mood (81.0%) and anxiety (39.2%) disorders. The only statistically significant gender difference was found in behavioral and emotional disorders (16.7% in men, 1.6% in women).

CONCLUSIONS

The mcB-based BPD prevalence estimate and psychiatric comorbidity was consistent with previous studies researching psychiatric outpatients with BPD. McBs appear to be a reliable and comprehensive data source for diagnostic information in research.

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.

Mentalizing in Adolescents with Borderline Personality Disorder

Mentalizing, recognized as the capacity to understand behaviors in the context of our own mental states and those of other people, is being researched more and more commonly in regard to various mental disorders. The research on mentalization focuses on, among other things, borderline personality disorder, which is at present perceived as an emerging problem in the population of adolescents. In order to summarize the currently accessible knowledge of mentalizing in adolescents with borderline personality disorder, we thoroughly analyzed relevant publications. Based on the available literature, it can be concluded that the mentalizing ability of adolescents with borderline personality disorder can be impaired. The evidence demonstrates that they are prone to hypermentalizing, defined as an overattribution of mental states to other people. However, this tendency has not been proven to be specific to teenagers with this disorder. Moreover, the existing data suggest that young people with borderline personality exhibit a reduced capacity to mentalize their own inner states.

Key insights from studies on the stability of personality disorders in different age groups

While for decades, temporal stability has been conceived as a defining feature of personality disorders (PDs), cumulative findings appear to question the stability of PDs and PD symptoms over time. However, stability itself is a complex notion and findings are highly heterogenous. Building upon a literature search from a systematic review and meta-analysis, this narrative review aims to capture key findings in order to provide critical implications, both for clinical practice and future research. Taken together, this narrative review revealed that unlike previous assumptions, stability estimates in adolescence are comparable to stability estimates in adulthood and PDs and PD symptoms are not that stable. The extent of stability itself depends yet on various conceptual, methodological, environmental, and genetic factors. While findings were thus highly heterogenous, they all seem to converge in a notable trend towards symptomatic remission, except for high-risk-samples. This challenges the current understanding of PDs in terms of disorders and symptoms and argues instead in favor of the AMPD and ICD-11 reintroducing the idea of self and interpersonal functioning as the core feature of PDs.

Alignment of Borderline Personality Disorder and Complex Post-traumatic Stress Disorder With Complex Developmental Symptomatology

Cluster analysis of maltreatment-related mental health symptoms manifested by adolescents in foster care suggest the absence of an underlying taxonomic structure. To test this further, we investigated alignment between mental health symptom profiles derived through cluster analysis and nominal diagnosis of Borderline Personality Disorder (BPD) and Complex Post-traumatic Stress Disorder (C-PTSD), among a sample of 230 adolescents in long-term foster care. Nominal DSM-V BPD and ICD-11 C-PTSD caseness was estimated from Child Behaviour Checklist and Assessment Checklist for Adolescents score algorithms, and alignment of case assignment with previously-derived symptom profiles was examined. Nineteen BPD and three C-PTSD nominal cases were identified. Low C-PTSD prevalence reflected low concordance between PTSD and 'disturbances in self organization' (DSO) case assignment. The BPD and C-PTSD cases were aligned to more complex and severe symptom profiles. While the complex and severe presentations identified in the present study included core symptoms and clinical signs of BPD, they were also characterised by clinical-level inattention/over-activity and conduct problems. The present findings provide some support for the validity of the BPD construct for describing complex and severe psychopathology manifested by adolescents in foster care, and no support for the C-PTSD construct. However, the symptom profiles point to high variability in combinations of multiple symptom types that does not conform to traditional definitions of a 'diagnosable' mental disorder. Further research is needed to determine if complex post-maltreatment symptomatology can be validly conceptualised as one or more complex disorders.

The diagnosis that should speak its name: why it is ethically right to diagnose and treat personality disorder during adolescence

Although national guidelines explicitly state that personality disorder can be diagnosed and treated in young people aged 12 to 18 years (adolescents), most clinicians remain hesitant. This creates a gap between science and practice, which we argue is largely motivated by moral reasons and, therefore, is best challenged by ethical arguments. We provide seven arguments in support of the notion that it is ethically right to diagnose and treat personality disorder when it occurs in adolescents. Central to these arguments is the scientific evidence that features of personality disorder are among the best predictors of a complex cluster of psychopathology leading to impairments in many areas of current and future mental, social and vocational functioning. We argue that intervention during adolescence and young adulthood is not only humane, but also critical for efforts to avert the longstanding psychosocial and health problems that seem refractory to treatment in adults with personality disorder. Moreover, we argue that regular services are often inadequately equipped to meet the needs of young people with personality disorder and that the common 'stepped-care' approach should be replaced by a 'staged-care' approach. Finally, we argue that early detection and intervention might have anti-stigmatizing effects, similar to other areas of healthcare in which stigmatizing labels have changed meaning when the conditions to which they refer have become more amenable to treatment.

The stability of personality disorders and personality disorder criteria: A systematic review and meta-analysis

The aim of this systematic review and meta-analysis was to investigate the diagnostic, the dimensional mean-level, and rank-order stability of personality disorders (PDs) and PD criteria over time. EMBASE, PsycInfo, PubMed, and Web of Science were searched for peer-reviewed studies published in either English, German, or French between the first publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 and December 20, 2022. Inclusion criteria were a prospective longitudinal study design, assessing the stability of PDs or PD criteria over at least two measurement occasions at least one month apart, and using the same assessment at baseline and follow-up. Effect sizes included proportion of enduring cases (i.e., diagnostic stability), test-retest correlations (i.e., dimensional rank-order stability), and within-group standardized mean differences (i.e., dimensional mean-level stability), based on the first and last available measurement occasion. From an initial pool of 1473 studies, 40 were included in our analyses, covering 38,432 participants. 56.7% maintained the diagnosis of any PD, and 45.2% maintained the diagnosis of borderline PD over time. Findings on the dimensional mean-level stability indicate that most PD criteria significantly decreased from baseline to follow-up, except for antisocial, obsessive-compulsive, and schizoid PD criteria. Findings on the dimensional rank-order stability suggested moderate estimates, except for antisocial PD criteria, which were found to be high. Findings indicated that both PDs and PD criteria were only moderately stable, although between study heterogeneity was high, and stability itself depended on several methodological factors.

Diagnose- und Behandlungsbereitschaft der Borderline-Persönlichkeitsstörung im Jugendalter unter Therapierenden

Zusammenfassung: Theoretischer Hintergrund: Eine eingeschränkte Diagnosebereitschaft der Borderline-Persönlichkeitsstörung (BPS) im Jugendalter verhindert möglicherweise deren Früherkennung und -behandlung. Fragestellung: Die Studie zielt auf eine Quantifizierung von Diagnose- und Behandlungsbereitschaft der BPS im Jugendalter bei kinder- und jugend-/psychotherapeutischen/-psychiatrischen Therapierenden ab. Methode: Die Studie basiert auf einer Onlinebefragung von 207 Therapierenden. Ergebnisse: 32 % der Therapierenden würden ab dem 14. Lebensjahr, 56 % ab der Volljährigkeit und 12 % gar keine Diagnose einer BPS vergeben. Die Vorbehalte „mangelnde Stabilität der Persönlichkeit“ und „Sorge um Pathologisierung“ waren mit geringer Diagnosebereitschaft assoziiert. Insgesamt sind 72 % der Therapierenden bereit, Jugendliche mit BPS-Symptomatik zu behandeln. Diskussion und Schlussfolgerung: Mixed-Methods Ansätze könnten die Diskrepanz zwischen der Diagnose- und Behandlungsbereitschaft aufklären.

Die Borderline-Persönlichkeitsstörung im Jugendalter

Zusammenfassung: Die Borderline-Persönlichkeitsstörung (BPS) ist eine schwere psychische Erkrankung, die durch hohe Morbidität und Mortalität gekennzeichnet ist sowie mit einem niedrigen psychosozialen Funktionsniveau einhergeht. Die BPS zeigt sich oft mit Beginn der frühen Adoleszenz (ab dem 12. Lebensjahr). Neben repetitiver Selbstverletzung und Suizidalität bestehen häufig sowohl Symptome internalisierender (Depression und Angst) als auch externalisierender Störungen (Hyperaktivität und Substanzkonsum). Daher kommt einer differentialdiagnostischen Abklärung und der Diagnosestellung mit dem Ziel der Frühintervention im klinischen Alltag eine besondere Rolle zu. Die Psychotherapie stellt bei der BPS eine äußerst wirksame Behandlungsmethode dar, Belege für die Wirksamkeit von pharmakologischen Intervention fehlen. Der Schlüssel zu einer Verbesserung der Versorgung für Jugendliche mit BPS liegt in einer Generierung von Wissen zu Vorläufersymptomen sowie einer evidenzbasierten, stadienspezifischen Behandlung (frühe Behandlung bereits subklinischer BPS mit Behandlungsintensität abgestuft nach dem Schweregrad). Dieser Übersichtsartikel beleuchtet den aktuellen Stand der Forschung und gibt Empfehlungen für die therapeutische Arbeit in der klinischen Praxis.

Emerging personality in adolescence: developmental trajectories, internalizing and externalizing problems, and the role of mentalizing abilities

INTRODUCTION

Identifying longitudinal trajectories of emerging personality (EP) is crucial to highlight developmental patterns that might foster personality pathology in adolescence and early adulthood. Research on the exacerbation of personality pathology in adolescence identifies the significant contribution of internalizing and externalizing problems and suggests the importance of considering aspects such as mentalization, while accounting for gender differences.

METHODS

In our study, we adopted a mixed-model approach to (1) explore longitudinally EP (Adolescent Personality Structure Questionnaire; APS-Q) over 12 months in a sample of adolescents (N = 178, 62% females, mAGE = 15.04, SD = 1.27), accounting for gender effects. Moreover, (2) we assessed the longitudinal effect of internalizing and externalizing problems (Youth Self-Report; YSR-112) on EP. Finally, (3) we addressed the moderating role of mentalization (Movie Assessment for Social Cognition; MASC) in this developmental pathway.

RESULTS

Results highlighted a two-way pattern of EP. No changes were found in the level of difficulties in Self-acceptance, Investments and Goals, and Relationships with family dimensions. However, significant changes were found in personality functioning in the dimensions of Sense of Self, Aggression, and Relationships with friends. More, changes in difficulties in Sexuality emerged only in females. Also, gender differences emerged in the level of severity of EP. In addition, Internalizing and Externalizing problems differentially predicted difficulties in personality dimensions. Finally, mentalizing features moderated the relationship between Internalizing problems and Sense of Self and Internalizing problems and Self-acceptance, respectively.

CONCLUSIONS

Our contribution aligns with recent developmental models of personality pathology, suggesting that different personality dimensions develop at different paces. More, it highlights the predictive power of externalizing and internalizing problems on difficulties in personality dimensions. Finally, it advances the discussion on the contribution of mentalizing abilities to EP.

Emotion Recognition and the Screening Instrument for Borderline Personality Disorder (SI-Bord): Outcomes and Community-Based Validation

Background: Borderline Personality Disorder (BPD) is a psychiatric condition characterized by impulsivity, affect instability, dysregulation, low self-image, and interpersonal difficulties. There are many instruments to measure traits of BPD, however, few can be administered quickly. The Screening Instrument for Borderline Personality Disorder (SI-Bord) is an instrument offering a brief administration time with comparable psychometric properties to more comprehensive measures. The present study aimed to evaluate the psychometric properties of the SI-Bord in a healthy community-based sample and its relatedness to measures of social cognition. Methods: A community-based sample of participants completed an online survey consisting of measures of BPD traits and social cognition including: the Screening Instrument for Borderline Personality Disorder (SI-Bord), the Personality Assessment Inventory (PAI), the Florida Affect Battery (FAB), the Interpersonal Reactivity Index (IRI), and the Narcissistic Personality Inventory (NPI). Reliability was assessed using Cronbach’s alpha and inter-item correlations. Validity was assessed using factor analysis, examining associations with other measures of BPD traits, and examining associations with measures not measuring BPD traits. Results: 151 participants were included in the study. Participants’ age ranged from 20−76 (mean age of 38.79 ± 12.37) and comprised 76 females (50.33%) and 75 males (49.67%). Good internal consistency was found with a Cronbach’s alpha of 0.71. Good inter-item reliability was found with a mean inter-item cross correlation of 0.25, with each item of the SI-Bord showing an inter-item correlation coefficient of >0.5. Factor analysis identified good construct validity with a strong singular dimension explaining a large proportion of variance (Question 1). The SI-Bord showed good concurrent validity with significantly strong positive correlations with the subscales of the PAI borderline scale measuring affect instability (r = 0.60; p < 0.001), identity problems (r = 0.67; p < 0.001), negative relationships (r = 0.61; p < 0.001), total score (r = 0.76; p < 0.001), and to a moderately strong positive correlation with self-harm (r = 0.39; p < 0.001). The SI-Bord was not correlated with the NPI-16 (r = 0.131; p = 0.11), showing good divergent validity. Conclusions: These findings support the SI-Bord as a quick and useful screening tool for traits associated with BPD. Further clinical validation is warranted.

Are adolescents and young adults in substance use disorder treatment as engaged in the research recruitment process as those in general behavioral health treatment?

BACKGROUND AND OBJECTIVE

While prior research suggests that individuals with substance use disorders (SUD) are generally more difficult to engage in research, little is known about the research engagement of adolescents and young adults (AYA) in SUD treatment as it compares to peers seen in general behavioral health settings. This study aimed to systematically compare engagement in virtual research recruitment between AYA in SUD treatment and AYA in behavioral health (BH) treatment.

METHODS

Study staff contacted patients ages 16-30 at three outpatient clinics to recruit them for a naturalistic longitudinal online study. Staff documented whether patients answered the phone, expressed interest in the study, answered questions regarding eligibility, and enrolled in the study.

RESULTS

Overall, 18% (n = 117) of those contacted by phone enrolled in the study. The rate of AYA reached did not significantly differ between those in SUD treatment (51%) and those in BH treatment (55%). Among those who were reached, those in SUD and BH treatment did not significantly differ (all p > 0.05) in rates of being interested in the study (SUD: 58%; BH: 49%), completing the phone screen (SUD: 46%; BH: 41%) or enrolling in the study (SUD: 33%; BH: 35%).

CONCLUSIONS

Overall, we found that engaging AYA in SUD treatment in virtual naturalistic longitudinal research was no more difficult than engaging AYA seen in general behavioral health settings. Future research should examine generalizability of engagement in naturalistic research to other study designs and explore the continuity of this effect into study retention and completion.

Adolescence as a peak period of borderline personality features? A meta-analytic approach

This meta-analysis of cross-sectional data aimed to shed light on the often assumed peak in mean-level of borderline personality features during middle to late adolescence (i.e. age 17–22). Borderline personality features were operationalized through the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II). Search terms were entered into PsycINFO and Scopus. A total of 168 samples were included in the analyses, comprising 25,053 participants. Mean age ranged from 14.35 to 51.47 years ( M = 29.01, SD = 8.52) and mean number of borderline personality features from 0 to 8.10 ( M = 4.59, SD = 2.34). The hypothesized peak between age 17 and 22 was not substantiated by the confirmatory ANOVA analysis. However, subsequent exploratory GAM analysis provided evidence for a peak at 29.4 years. Caution is needed in interpreting these findings given that different trends appeared when GAM models were constructed separately for community, patient and borderline personality disorder (BPD) samples. Age differences in community samples indicated a significant linear decline in mean-level of borderline personality features over time. A linear rising trend was found in BPD samples. As a between-person mean-level approach was used in the current study, future longitudinal studies are needed to substantiate if between-person age difference generalize to within-person changes.

Borderline personality disorder traits and mentalising ability: The self-other social cognition paradox

Objective

Borderline personality disorder (BPD) is a psychiatric condition characterised by a pervasive pattern of impulsivity, low self-image, and interpersonal conflicts. Previous findings indicate a mixed relationship between BPD and social cognition; little research as investigated whether BPD traits influence performance on specific elements of social cognitive tasks, i.e., positive/negative valence.

Method

Community-based typical controls (n = 151; 51% female) were recruited through an online survey. Participants completed aspects of the Personality Assessment Inventory pertaining to BPD traits, the Interpersonal Reactivity Index, and measures of both emotion recognition and mentalising.

Results

Following group stratification into high/low BPD traits, participants with high BPD traits were observed to perform significantly better when identifying negative valence stimuli. Furthermore, high levels of affect instability was found to significantly influence negative valence recognition.

Conclusion

This research highlights previous research which shows a paradox between higher performance on measures of social cognition, with a group of individuals who report significant interpersonal and relational difficulties. This research supports the assessment of social cognitive processes for people with BPD and/or high BPD traits to support clinical formulation of strengths and difficulties.

Inter-Rater Reliability of the Structured Interview of DSM-IV Personality (SIDP-IV) in an Adolescent Outpatient Population

Personality disorders (PDs) are a class of mental disorders which are associated with subjective distress, decreased quality of life and broad functional impairment. The presence of one or several PDs may also complicate the course and treatment of symptom disorders such as anxiety and depression. Accurate and reliable means of diagnosing personality disorders are thus crucial to ensuring efficient treatment planning and resource allocation, a fact which is widely acknowledged within the adult mental health field. In adolescents, on the other hand, the consensus view has been that the rapid and discontinuous processes of normal personality development render the construct of PD in adolescents clinically unhelpful and conceptually dubious. However, recent research has established the reliability and validity of the construct, heralding an increased interest in the field, with important conceptual and clinical implications. The present article presents reliability data for the Structured Interview of DSM-IV Personality (SIDP-IV) in an adolescent outpatient population. For this study, 25 interviews conducted by experienced clinicians were blindly re-scored based on sound recordings, which allowed for the calculation of intra-class correlation metrics. The intra-class correlation coefficient for categorical diagnosis of specific personality disorders was found to be 0.876 (95% CI 0.718-0.945); Cohen's kappa for presence/absence of personality diagnosis was found to be 0.896. The present study found excellent intra-rater reliability for the sample, which suggests that the SIDP-IV is a suitable instrument for assessing personality pathology in adolescent populations.

A bifactor model of personality organization in adolescence: the validity of a brief screening measure assessing severity and core domains of functioning

BACKGROUND

Both the latest edition of the DSM-5 as well as the new ICD-11 have established a new focus in the diagnosis of personality disorders: the assessment of personality functioning. This recent shift in focus converges with long-standing psychodynamic conceptualizations of personality pathology, particularly Kernberg's object relations model. Although a significant amount of research supports these models in adults, much less is known about the validity of these frameworks in youth. Considering the paucity of brief measures of personality functioning in adolescents, the current study aimed to develop and investigate the validity of the Inventory of Personality Organization for Adolescents-Short Form, a theoretically-informed measure assessing severity and core domains of functioning in adolescents.

METHODS

A total sample of N = 525 adolescents aged 13 to 19 years were recruited through a community University-Health Psychology Clinic as current patients (n = 94) or who responded to an online research call (n = 431).

RESULTS

Results indicate that a bifactor model provided the best fit to the data and consisted of a general factor reflecting core self-other functioning and three specific factors, representing additional dimensions of personality organization.

CONCLUSIONS

A brief 15-item version of the IPO-A was successfully derived for time-efficient screening of personality pathology in youth. Similarities with the ICD-11 framework are discussed.

Young People With Borderline Personality Disorder Have an Increased Lifetime Risk of Being the Victim of Interpersonal Violence

This study aimed to examine the lifetime risk of being the victim of criminal or violent offenses among young people with borderline personality disorder (BPD) features (1-9 DSM-IV criteria). Demographic and diagnostic data from 492 outpatients who attended a specialist public mental health service for 15- to 25-year-olds between January 1998 and March 2008 were linked with offending data from a state-wide police database, collected between March 1993 and June 2017, in order to establish victimization history. This included information on criminal offenses perpetrated against these young people and intervention orders implemented to protect them from being victimized by another person's violent behavior. Logistic regression analyses, adjusted for sex and co-occurring mental state disorders, were conducted on n = 378 who had complete data (76.5% females). As hypothesized, BPD diagnosis and number of BPD criteria were both significantly associated with an increased risk of being the victim of a violent offense and the complainant of a family violence intervention order. Anger and impulsivity independently predicted a higher risk of being the victim of a violent offense, while unstable relationships, impulsivity, and affective instability independently predicted a higher risk of being the complainant of a family violence intervention order. No significant association was found between BPD and the risk of being the victim of a nonviolent offense. These findings indicate that young people with any BPD features (even below the DSM diagnostic threshold) are at increased risk for victimization by interpersonal violence. Moreover, this risk increases according to the number of BPD criteria. This issue needs to be addressed by prevention and early intervention programs (e.g., by working on self-assertion and interpersonal skills, taking into account the possible influence of previous traumatizing relationship experiences).

Debate: Child and adolescent mental health professionals have a responsibility to diagnose Personality Disorder

In the United Kingdom, mental health professionals have been historically reluctant to diagnose Personality Disorder in young people over many decades, and there is little evidence that much has changed. However, there are consequences to this reluctance. Personality Disorders in young people are absent from national prevalence studies and research is sparse, as a lack of diagnosed patients makes it hard to recruit for studies. Consequently, national policy-makers lack an awareness of the scale of the problem and the focus on service provision to address it. Deliberate misdiagnosis of Personality Disorder due to professionals' unwillingness to use the diagnosis is not only unethical but can also cause harm as it stops young people from receiving the evidence-based interventions and support that they require. Young people and families often experience reassurance and relief when they receive an accurate diagnosis. Professionals need to reconsider whether their reluctance to diagnose is in their patients' best interests.

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.

Prevalence and 10-Year Stability of Personality Disorders From Adolescence to Young Adulthood in a High-Risk Sample

Background

With the implementation of the 11th edition of the International Classification of Diseases (ICD-11) in early 2022, there will be a radical change in the framework and process for diagnosing personality disorders (PDs), indicating a transition from the categorical to the dimensional model. Despite increasing evidence that PDs are not as stable as previously assumed, the long-term stability of PDs remains under major debate. The aim of the current paper was to investigate the categorical and dimensional mean-level and rank-order stability of PDs from adolescence into young adulthood in a high-risk sample.

Methods

In total, 115 young adults with a history of residential child welfare and juvenile-justice placements in Switzerland were included in the current study. PDs were assessed at baseline and at a 10-year follow-up. On a categorical level, mean-level stability was assessed through the proportion of enduring cases from baseline to follow-up. Rank-order stability was assessed through Cohen's κ and tetrachoric correlation coefficients. On a dimensional level, the magnitude of change between the PD trait scores at baseline and at follow-up was measured by Cohen's d. Rank-order stability was assessed through Spearman's ρ.

Results

The prevalence rate for any PD was 20.0% at baseline and 30.4% at follow-up. The most frequently diagnosed disorders were antisocial, borderline, and obsessive-compulsive PDs, both at baseline and at follow-up. On a categorical level, the mean-level stability of any PD was only moderate, and the mean-level stability of specific PDs was low, except of schizoid PD. Likewise, the rank-order stability of any PD category was moderate, while ranging from low to high for individual PD diagnoses. On a dimensional level, scores increased significantly for most PDs, except for histrionic traits, which decreased significantly from baseline to follow-up. Effect sizes were generally low. The rank-order stability for dimensional scores ranged from low to moderate.

Conclusion

The findings indicate low to moderate stability of Pds and Pd traits from adolescence to adulthood, which supports the growing evidence that categorical diagnoses of Pds are quite unstable. This in turn, emphasizes the use of the upcoming ICD-11 that Acknowledgments Pds to be only "relatively" stable.

Psychometric Properties of a Cultural Adapted Version of the Assessment of Identity Development in Adolescence in Panama

The Assessment of Identity Development in Adolescence (AIDA) is a self-report instrument to detect pathological development of Identity. In Panamá, psychometric instruments for assessment of psychopathology in adolescence are lacking. Our aim was to develop a valid and reliable version of the AIDA Inventory for Panamanian Population. AIDA was adapted to Spanish considering cultural aspects of Panamanian population. Two pilot tests were performed prior to main test to assess item-total correlation at subscale, primary scale and total scale levels and internal consistency at subscale level. A mixed sample of students and PD patients (N = 315) completed the AIDA inventory, the "Strength and Difficulties Questionnaire" and "Defense Style Questionnaire-40." AIDA was retested in a sub sample from school population (n = 98). The Structured Clinical Interview for Axis II Disorders was used for diagnosis of personality disorders in the patient sample (n = 25). Psychometric properties were tested to assess internal consistency, reliability, factorial validity, convergent validity, and criterion validity. AIDA Panama showed excellent internal consistency for the total scale Identity Diffusion with Cronbach's α:0.94 and a retest reliability of 0.84. A Bifactorial CFA was modeled to assess the dimensionality of the inventory. The proportion between OmegaH and Omega at total scales 96% of the variance is explained by a general factor. Furthermore, the Explained Common Variance for the General Factor is 73% supporting unidimensionality. In line with theory, AIDA total scale showed a high positive correlation (r = 0.67) with Total Difficulties scale and high positive correlation (r = 0.71) with Immature Defense scale. The AIDA total score differed highly significant (p = 0.000) between the patient sample and the students with a large effect size (d = 1.02).

CONCLUSION

The adaptation and validation of AIDA for Panamanian adolescent population was successful with good psychometric properties and significant correlations with related psychopathological constructs. AIDA showed high clinical validity by providing a valid discrimination between the school sample and a diagnosed PD sample, in line with the assumption that impaired identity functioning is at the core of personality disorders, especially in adolescence.

Influence of Identity Development on Weight Gain in Adolescent Anorexia Nervosa

BACKGROUND

Anorexia Nervosa (AN) typically begins during early adolescence, an important phase of personality development. A substantial proportion of adolescent AN patients shows impaired personality functioning, which might be a relevant but understudied aspect of illness severity. The developmental status of identity as key element of personality is suggested to influence inpatient treatment outcome in adolescents with AN.

METHODS

This study analyzed existing data of N = 60 adolescents with AN. Multilevel models assessed the influence of identity functioning, measured by the Assessment of Identity Development in Adolescence (AIDA) at admission, on weight gain [BMI (body mass index), BMI-SDS (BMI standard deviation score)] during 10 weeks of inpatient treatment. Moreover, the influence of other indicators of illness severity, i.e., eating disorders and comorbid psychopathologies, was explored.

RESULTS

As expected, higher AIDA scores negatively influenced the course of weight gain. A similar effect was observed for other psychopathology measures, especially body image distortion. In general, higher weight at admission was associated with less weight gain. Higher weight at admission was also predicted by higher other psychopathology measures, but not AIDA scores.

CONCLUSION

The course of weight gain during inpatient treatment was hampered in adolescent AN patients who have difficulties developing a stable identity. Unlike other aspects of psychopathology, this was independent of the initial weight. Thus, in addition to the level of underweight and other aspects of psychopathology, difficulties in identity development constitute a relevant aspect of illness severity in AN. This recommends consideration of identity development during treatment.

Risikofaktoren für und Stabilität einer Persönlichkeitsstörung vom Jugendalter bis ins junge Erwachsenenalter in einer Hochrisikopopulation

Zusammenfassung. Theoretischer Hintergrund: Studien zeigen, dass Persönlichkeitsstörungen (PS) weniger stabil und bei einer frühzeitigen Erkennung gut behandelbar sind. Fragestellung: Ziel dieser Studie ist, 1) die Prävalenz von PS bei ehemalig fremdplatzierten jungen Erwachsenen zu beschreiben, 2) die kategoriale Stabilität von PS vom Jugendalter bis ins junge Erwachsenenalter zu bestimmen und 3) prospektive Risikofaktoren für eine PS im Erwachsenenalter zu identifizieren. Methoden: 180 ehemalig fremdplatzierte junge Erwachsene ( M = 26.3 Jahre) aus einer schweizweiten Längsschnittstudie wurden untersucht. Ergebnisse: 35 % der Teilnehmenden wiesen eine PS auf. Die kategoriale Stabilität belief sich auf 47 %. Folgende Risikofaktoren für eine PS im Erwachsenenalter wurden identifiziert: vorangehende PS, psychopathische Persönlichkeitszüge, Substanzmissbrauch, emotionale Vernachlässigung, kumulierte Misshandlungserfahrungen und Deliktschwere. Diskussion und Schlussfolgerung: Die kategoriale Stabilität irgendeiner PS in dieser Stichprobe gilt als mittelgradig. Dies unterstreicht die Notwendigkeit, PS nicht mehr mit einem lebenslangen, unveränderbaren Schicksal gleichzusetzen. Das Erkennen möglicher Risikofaktoren ist eine wichtige Voraussetzung, um individuelle Behandlungsmöglichkeiten zu gewährleisten und einer Chronifizierung entgegenzuwirken.

Cardiac autonomic functioning and clinical outcome in adolescent borderline personality disorder over two years

The present study aimed to expand on previous findings that pre-treatment autonomic nervous system (ANS) functioning serves as a predictor of clinical outcome in adolescent borderline personality disorder (BPD), while examining whether the relationship between ANS functioning and treatment outcome may vary as a function of early life maltreatment (ELM). ANS stress response was examined considering changes in heart rate (HR) and vagally-mediated heart rate variability (vmHRV) over different conditions of the Montreal Imaging Stress Task (MIST) in a clinical sample of N = 27 adolescents across the spectrum of BPD severity. Participants received in- and/or outpatient treatment, while clinical data was assessed at routine follow-ups. Clinical outcome was defined by change in the number of fulfilled BPD criteria (as measured using the SCID-II), severity of psychopathology (CGI-S), and global level of functioning (GAF), measured 12 and 24 months after baseline assessments. Mixed-effects (random-intercept/random slope) linear regression models were calculated to examine markers of ANS function as potential predictors of clinical outcome. Irrespective of the presence of ELM exposure, both vmHRV resting-state and stress recovery measures were identified as significant predictors of clinical outcome over time. This study adds to the existing literature by replicating and expanding on preliminary findings, considering also physiological reactivity and recovery in addition to resting-state measures of ANS functioning. The present results further highlight the potential of markers of ANS functioning to serve as objective measures in the process of monitoring patient progress and to make predictions regarding treatment outcome in psychiatry research.

[A Multidimensional Assessment of Emotion Regulation in Adolescent Non-Suicidal Self-Injury]

The ability to regulate one's emotions (emotion regulation, ER) with regard to individual short- and long-term goals presents one of the most central human skills. A disrupted development of ER skills is associated with psychopathological outcomes. Non-suicidal self-injury (NSSI) presents a frequent and impairing phenomenon among young individuals. Disruptions regarding various aspects of ER are involved in the development and maintenance of NSSI. In the present study, we examined ER from a multidimensional perspective, including a sample of female adolescents meeting DSM-5 criteria for NSSI disorder (N = 30) and a psychologically healthy control group (N = 30). In line with results from previous studies, female adolescents with NSSI exhibited considerable difficulties regarding all aspects of ER investigated. Furthermore, various aspects of ER were distinctly linked with depressive and BPD symptomatology. Differences in NSSI frequency between participants largely went back to difficulties regarding specific aspects of ER, in combination with the self-rated severity of exposure to early life maltreatment. With regard to clinical practice, the use of interventions to improve particular aspects of ER, under simultaneous consideration of the individual developmental history and psychopathological impairment, might provide an efficient approach to mediate long-lasting change in the treatment of deliberate self-harm.

Associations between borderline personality disorder features and the risk of first onset major depressive disorder: Findings from a 2-year longitudinal study in a sample of first-year university students in China

BACKGROUND

The objective of this study was to estimate the associations between specific BPD features on the risk of first onset MDD over 2 years and to investigate the roles of sex, baseline depression and anxiety in the associations.

METHODS

A longitudinal study of Chinese first-year university students aged between 15 and 24 years and who did not have a lifetime MDD (n = 7,627). Random effect logistic regression modeling was used to estimate the associations between specific BPD features, the number of BPD features, and the risk of MDD.

RESULTS

The feeling of emptiness (OR = 2.14, 95% CI: 1.57, 2.92), paranoid/ dissociation (OR = 2.01, 95% CI: 1.43, 2.82), affective instability (OR = 1.71, 95% CI: 1.22, 2.39) conferred significant risk of MDD. Baseline depression and anxiety interacted with unstable relationship, identity disturbance and paranoid/disassociation in relation to the risk of MDD. A higher number of BPD features is associated with an increased risk of MDD.

LIMITATIONS

Data collection relied on self-report. Thus, recall and reporting biases are possible. Due to the pandemic public health restrictions, we had to change the method of data collection at second annual assessment, which resulted in a lower response rate (66.5%).

CONCLUSIONS

Mental health professionals should pay attention to the presence of BPD features in youth and young adults, as they are at high risk of developing a MDD in a short time period, and the risk increases with the number of BDP features.

Borderline Personality Disorder Diagnosis and Symptoms in Outpatient Youth as Risk Factors for Criminal Offenses and Interpersonal Violence

The aim of the current study was to examine the risk for offending among outpatient youth with borderline pathology. Demographic and diagnostic data from 492 outpatients who attended a public mental health service for 15-to 25-year-olds between January 1998 and March 2008 were linked with information regarding criminal offenses and intervention orders collected from a statewide police database between March 1993 and June 2017. BPD diagnosis and number of BPD criteria were both associated with an elevated risk for violent and nonviolent offenses and family violence intervention orders. Moderation analyses revealed that the number of BPD criteria might affect males and females differently in terms of offending. Both impulsivity and anger independently predicted the risk for violent and nonviolent offenses and family violence intervention orders. Early detection of increased risk of offending among youth with BPD features is essential to develop targeted treatments for criminal or violent behavior.

Autonomic nervous system activity and dialectical behavioral therapy outcome in adolescent borderline personality pathology

OBJECTIVES

We aimed to investigate whether pre-treatment cardiac autonomic nervous system (ANS) activity, indexed by heart rate (HR) and heart rate variability (HRV) predicts clinical outcome and therapy drop-outs in adolescents with borderline personality (BPD) pathology receiving dialectical behavioural therapy (DBT-A). We further tested for an association between changes in ANS function and clinical outcome over time. Traumatic experiences were considered as potential confounding factor.

METHODS

N = 43 (95.4% female, M_age = 15.5 years) adolescents fulfilling at least sub-threshold criteria for BPD (≥3) were investigated before and after outpatient DBT-A as well as at follow-up. N = 10 patients dropped out of treatment (<50% of treatment sessions). Latent growth curve models were used for analyses.

RESULTS

Greater pre-treatment resting HRV significantly predicted clinical improvement (decrease in BPD pathology/increase of global functioning) over time. Pre-treatment ANS activity was unrelated to treatment drop-out. Further, changes in ANS activity over treatment were associated with changes in clinical outcome.

CONCLUSION

This study is the first providing evidence that pre-treatment HRV predicts and is related to treatment response in adolescent borderline personality pathology. Implications for the use of ANS measures in clinical practice and directions for future research are discussed.

Borderline personality disorder and adolescent suicide attempt: the mediating role of emotional dysregulation

BACKGROUND

Emotional dysregulation seems to be a core feature of Borderline Personality Disorders (BPD). In addition, recent research in the adolescent population has shown that suicidal behaviours have been associated with maladaptive strategies of emotion regulation.

METHODS

This study examined the relative contributions of emotional dysregulation to suicide attempt history in a clinical sample of borderline adolescents. Data were analyzed from 85 participants of the Collaborative European Research Network on Borderline Personality Disorder. Participants completed measures of BPD traits and symptoms, suicide behaviours, emotional dysregulation, attachment styles and lifetime depressive disorders.

RESULTS

In an SEM model, lifetime depressive disorders and insecure attachment styles have a significant direct effect on lifetime suicide attempt, but only lifetime depressive disorders have an indirect effect through emotion dysregulation. The results suggest that emotional dysregulation has a mediating role in suicide attempts among BPD adolescents.

CONCLUSIONS

These findings call for the development of interventions targeting the role of emotion dysregulation in effectively predicting and preventing suicidality in borderline adolescents.

Psychosocial functioning in adolescents with non-suicidal self-injury: the roles of childhood maltreatment, borderline personality disorder and depression

BACKGROUND

There is a lack of studies examining psychosocial functioning in patients with non-suicidal self-injury (NSSI), especially in adolescents, and rates of impaired functioning in existing literature vary considerably. These variations may be attributable to further risk factors that influence psychosocial functioning. Thus, the aim of the study was to examine whether adolescent NSSI patients with childhood maltreatment (CM), a known risk factor for lower psychosocial functioning, may differ from adolescent NSSI patients without CM, and whether these differences may be explained by the severity of comorbid disorders. Specifically, we examined whether severity of borderline personality disorder (BPD), depression and posttraumatic stress disorder may explain differences in psychosocial functioning in NSSI patients with and without CM.

METHODS

Data of 368 adolescents with NSSI disorder from an outpatient clinic were analyzed using structural equation modeling. Clinicans' rating of the Global Assessment of Functioning Scale (GAF) was collected, in addition to clinical interviews.

RESULTS

Results indicate that GAF scores were lower among NSSI patients with CM and that the difference in psychosocial functioning between these groups was explained by BPD and depression severity.

CONCLUSIONS

Psychosocial functioning in NSSI patients varies depending on whether they have experienced CM or not. Specifically, these differences seem to be attributable to higher BPD and depression severity in adolescent NSSI patients with CM. Clinicians should ensure to assess CM and focus on BPD and depression severity in this population. Treatment of BPD and depression may notably reduce psychosocial impairment in NSSI patients with CM.

A Qualitative Evaluation of Young People's, Parents' and Carers' Experiences of a National and Specialist CAMHS Dialectical Behaviour Therapy Outpatient Service

(1) Background: Dialectical Behaviour Therapy (DBT) is the recommended treatment for Borderline Personality Disorder (BPD) symptoms in adults, however, research investigating the effectiveness of DBT for adolescents is limited. The present study explores the experiences of young people and their parents/carers of a DBT service using qualitative methodology. (2) Methods: Young people and their parents/carers, who completed DBT within the National and Specialist Child and Adolescent Mental Health DBT Service based at the Maudsley Hospital in London, were asked questions regarding their experience of the service. Data was collected from young people who completed treatment between July 2019 and July 2020 (n = 18) and their parents and carers (n = 7). (3) Results: Amongst young people, the themes identified were: a new way of living, better understanding of self, new skills, person-centred approach, and relationships with others. Parent and carer interviews revealed themes of improved relationships, feeling supported, improved quality of life, and time/timing. (4) Conclusions: Young people reported improvements in emerging BPD symptomology after completing DBT. Parents and carers reported improvements in their young person and families since starting DBT. A longer DBT programme, earlier DBT intervention, and the time-consuming nature of DBT were highlighted as areas for improvement.

Mentalization-based treatment in groups for adolescents with Borderline Personality Disorder: 3- and 12-month follow-up of a randomized controlled trial

Mentalization-based treatment in groups (MBT-G) has never been tested in adolescents with Borderline Personality Disorder (BPD) in a randomized controlled trial. The current study aimed to test the long-term effectiveness of MBT-G in an adolescent sample with BPD or BPD features (≥ 4 DSM-5 BPD criteria). Hundred and eleven patients with BPD (n = 106) or BPD features (n = 5) were randomized to either (1) a 1-year modified MBT-G program comprising three MBT introductory sessions, five individual case formulation sessions, 37 weekly MBT group sessions, and six MBT-Parent sessions, or (2) treatment as usual (TAU), defined as at least 12 individual monthly treatment sessions with follow-up assessments at 3 and 12 months post treatment. The primary outcome was the score on the Borderline Personality Features Scale for Children (BPFS-C), and secondary outcomes included clinician-rated BPD symptoms and global level of functioning as well as self-reported self-harm, depression, externalizing and internalizing symptoms, and caregiver reports. There were no statistically significant differences between MBT-G and TAU on the primary outcome measure or any of the secondary outcomes. Both groups showed improvement on the majority of clinical and social outcomes at both follow-up points, although remission rates were modest with just 35% in MBT-G and 39% in TAU 2 years after inclusion into the study. MBT-G was not superior to TAU in improving borderline features in adolescents. Although improvement was observed equally in both interventions over time, the patients continued to exhibit prominent BPD features, general psychopathology and decreased functioning in the follow-up period, which points to a need for more research and better understanding of effective components in early intervention programs. The ClinicalTrials.gov identifier is NCT02068326.

The relation between measures of explicit shame and borderline personality features in adolescent inpatients

BACKGROUND

Shame is a highly negative emotion frequently experienced by individuals with borderline personality disorder (BPD) as well as those with internalizing or externalizing psychopathology. However, few studies have examined whether shame is related to BPD above and beyond other psychopathology. Further, although feelings of shame peak during adolescence, coinciding with the onset of BPD, very few studies have examined the relationship between shame and BPD in adolescence. Therefore, the current study examined (1) whether levels of shame differ between adolescent psychiatric inpatients with and without BPD and (2) whether borderline personality pathology accounts for additional variance in the experience of shame above and beyond internalizing and externalizing psychopathology.

METHODS

Adolescent psychiatric inpatients (n = 184, 67% female, M age = 15.26) completed clinical interviews and self-report measures as well as self-report measures of three types of explicit shame: state-shame, shame-proneness, and trait-shame.

RESULTS

T-tests revealed that adolescents with BPD reported significantly higher levels of each type of explicit shame. In hierarchical regression models, borderline personality features explained significant additional variance in shame-proneness and trait-shame while controlling for age, gender, and internalizing and externalizing psychopathology.

LIMITATIONS

Our sample was limited by a lack of demographic diversity and healthy control group, and the study did not examine relations with unique internalizing/externalizing disorders or features of BPD.

CONCLUSIONS

Our findings contribute to growing evidence that shame is an important component of BPD, particularly during adolescence, and suggest that shame should be addressed in treatment.

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.

Identity Diffusion as the Organizing Principle of Borderline Personality Traits in Adolescents-A Non-clinical Study

Growing evidence shows that diagnosing and treating borderline personality disorder (BPD) is of high relevance for affected youths. Although identity crisis is part of the normative developmental process, identity diffusion is a potential candidate for being an appropriate concept in further developing screening tools and interventions for BPD treatment in adolescence. We hypothesized that severity of borderline traits (as indicated by the strength of their associations with identity diffusion) would be negatively associated with non-clinical adolescents' endorsement of borderline features' presence. We also hypothesized that identity diffusion had a central role in the network of borderline personality traits and could be conceived of as a latent organizing principle of borderline personality disorder. In our study, 169 non-clinical adolescents (81 girls and 88 boys; M _age = 15.38; SD_age = 1.52) filled out self-report measures of borderline personality features and identity diffusion. According to our results, having strong feelings and interpersonal sensitivity were the two most endorsed borderline personality features. Borderline personality features were positively correlated with identity diffusion. The more severe a borderline personality feature was, the less relevant it was for non-clinical adolescents. According to a network analysis, identity diffusion was the most central and least redundant element of the network of borderline personality traits. Results are discussed from a clinical point of view, further encouraging professionals to use identity diffusion screening tools to detect BPD in adolescence.

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.

Comorbidity Between Non-suicidal Self-Injury Disorder and Borderline Personality Disorder in Adolescents: A Graphical Network Approach

In 2013, DSM-5 urged for further research on non-suicidal self-injury (NSSI) and defined NSSI disorder (NSSI-D) for the first time separate from borderline personality disorder (BPD). However, research on the comorbidity between NSSI-D and BPD symptoms is still scarce, especially in adolescent populations. The current study selected 347 adolescents who engaged at least once in NSSI (78.4% girls, M age = 15.05) and investigated prevalence, comorbidity, gender differences, and bridge symptoms of NSSI-D and BPD. Network analysis allowed us to visualize the comorbidity structure of NSSI-D and BPD on a symptom-level and revealed which bridge symptoms connected both disorders. Our results supported NSSI-D as significantly distinct from, yet closely related to, BPD in adolescents. Even though girls were more likely to meet the NSSI-D criteria, our findings suggested that the manner in which NSSI-D and BPD symptoms were interconnected, did not differ between girls and boys. Furthermore, loneliness, impulsivity, separation anxiety, frequent thinking about NSSI, and negative affect prior to NSSI were detected as prominent bridge symptoms between NSSI-D and BPD. These bridge symptoms could provide useful targets for early intervention in and prevention of the development of comorbidity between NSSI-D and BPD. Although the current study was limited by a small male sample, these findings do provide novel insights in the complex comorbidity between NSSI-D and BPD symptoms in adolescence.

Developmental Course of Personality Disorder Traits in Childhood and Adolescence

Developmental patterns of personality pathology traits are not well delineated from childhood through late adolescence. In the present study, participants (N = 675, 56% female) were recruited to create three cohorts of third (n = 205), sixth (n = 248), and ninth (n = 222) graders to form an accelerated longitudinal cohort design. We assessed six PD (avoidant, dependent, histrionic, narcissistic, borderline, schizotypal) traits based on DSM-IV trait diagnostic conceptualizations via parent report at baseline, 18 months, and 36 months. According to parent report, mean levels of avoidant, dependent, histrionic, narcissistic, borderline, and schizotypal traits all declined for both boys and girls. The changes in dependent and histrionic traits were of medium effect size, and the changes in avoidant, narcissistic, borderline, and schizotypal traits were of small effect size. Over the 3 years of the study, the traits of each PD also demonstrated moderate to high rank-order stability.

Familial factors and the risk of borderline personality pathology: genetic and environmental transmission

BACKGROUND

Parental characteristics and practices predict borderline personality disorder (BPD) symptoms in children. However, it is difficult to disentangle whether these effects are genetically or environmentally mediated. The present study examines the contributions of genetic and environmental influences by comparing the effects of familial risk factors (i.e. parental psychopathology and borderline traits, maladaptive parenting, marital discord) on child BPD traits in genetically related (biological) and non-related (adoptive) families.

METHODS

Data are from 409 adoptive and 208 biological families who participated in the Siblings Interaction and Behavior Study (SIBS) and 580 twin families the Minnesota Twin Family Study (MTFS). Parent characteristics and practices included parental psychopathology (measured via structured clinical interviews), parental BPD traits, parenting behaviors, and marital discord. A series of multi-level regression models were estimated to examine the relationship of familial risk factors to child BPD traits and to test whether children's adoptive status moderated the association.

RESULTS

Symptom counts of parents' conduct disorder, adult antisocial behavior, nicotine, alcohol, and illicit drug dependence, and paternal BPD traits substantially predicted child BPD traits only in biological offspring, implying genetic transmission. Maternal BPD traits and both maternal and paternal conflict, lack of regard, and lack of involvement predicted offspring BPD traits regardless of the adoptive status, implying environmental transmission.

CONCLUSIONS

Parental externalizing psychopathology and father's BPD traits contribute genetic risk for offspring BPD traits, but mothers' BPD traits and parents' poor parenting constitute environmental risks for the development of these offspring traits.

Examining the predictive association of irritability with borderline personality disorder in a clinical sample of female adolescents

OBJECTIVES

Borderline personality disorder (BPD) is a disorder associated with emotion dysregulation and is common in clinical samples of adolescents. The identification and delineation of BPD from other disorders is important, yet methods for effectively screening for BPD are lacking. Here, we examine whether irritability can be used as a screening item for BPD in adolescents at risk for the disorder.

METHODS

We assessed Diagnostic Interview for Borderline-Revised and Development of Well-Being Assessment scores in a clinical sample of female adolescents ages 12-17 (n = 78) to identify BPD and group cases into 'irritable' and 'non-irritable' mood types, respectively. We then examined the prevalence of irritability and its predictive association with BPD.

RESULTS

The prevalence of BPD was 26% (n = 20). There was a significant association between irritable mood and BPD, specifically (χ² (1) = 17.740, p < 0.001). Irritability was endorsed in all (n = 20) BPD cases (sensitivity: 100%), while in non-BPD cases (n = 58), irritability was endorsed in 27 (specificity: 53%; positive predictive value: 0.33; and negative predictive value: 1.0).

CONCLUSION

Irritability is a highly sensitive screening item for BPD in adolescents. The absence of irritability in an adolescent may be an important clinical tool to rule out BPD. © 2020 John Wiley & Sons, Ltd.

Personality disorder and functioning in major depressive disorder: a nested study within a randomized controlled trial

Objective:

This study aimed to determine if personality disorder (PD) predicted functional outcomes in patients with major depressive disorder (MDD).

Methods:

Data (n=71) from a double-blind, randomized, placebo-controlled 12-week trial assessing the efficacy of 200 mg/day adjunctive minocycline for MDD were examined. PD was measured using the Standardized Assessment of Personality Abbreviated Scale. Outcome measures included Clinical Global Impression – Improvement (CGI-I), Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), Social and Occupational Functioning Scale (SOFAS), and Range of Impaired Functioning (RIFT). Analysis of covariance was used to examine the impact of PD (dichotomized factor [≥ 3] or continuous measure) on the outcome measures-treatment group correlation.

Results:

PD was identified in 69% of the sample. After adjusting for age, sex, and baseline scores for each of the outcome measures, there was no significant difference between participants with and without PD on week 12 scores for any of the outcome measures (all p > 0.14).

Conclusion:

In this secondary analysis of a primary efficacy study, PD was a common comorbidity among those with MDD, but was not a significant predictor of functional outcomes. This study adds to the limited literature on PD in randomized controlled trials for MDD.

Psychopathological outcomes of adolescent borderline personality disorder symptoms

OBJECTIVE

Despite considerable morbidity and functional losses associated with adolescent borderline personality disorder, little is known about psychopathological outcomes. This study examined associations between adolescent borderline personality disorder symptoms and subsequent depressive, psychotic and hypomanic symptoms.

METHODS

We used data from the Avon Longitudinal Study of Parents and Children. Participants were adolescents living in the community who had data for all longitudinal outcomes (N = 1758). We used logistic regression and path analysis to investigate associations between borderline personality disorder (five or more probable/definite symptoms) reported at age 11-12 years and depressive and psychotic symptoms reported at age 12 and 18, and lifetime hypomanic symptoms reported at age 22-23 years.

RESULTS

Adolescent borderline personality disorder symptoms were associated with psychotic symptoms (odds ratio: 2.36, confidence interval: [1.82, 3.06]), diagnosis of depression at age 18 years (odds ratio: 1.30, confidence interval: [1.03, 1.64]) and hypomanic symptoms (odds ratio: 2.89, confidence interval: [2.40, 3.48]) at 22-23 years. Path analysis controlling for associations between all outcomes indicated that borderline personality disorder symptoms were independently associated with depressive symptoms (β = 0.97, p < 0.001) at 12 years and hypomanic (β = 0.58, p < 0.01) symptoms at 22-23 years. Borderline personality disorder symptoms were also associated with psychotic symptoms at age 12 years (β = 0.58, p < 0.01), which were linked (β = 0.34, p < 0.01) to psychotic symptoms at age 18 years.

CONCLUSION

Adolescents with borderline personality disorder symptoms are at future risk of psychotic and hypomanic symptoms, and a diagnosis of depression. Future risk is independent of associations between psychopathological outcomes, indicating that adolescent borderline personality disorder symptoms have multifinal outcomes. Increasing awareness of borderline personality disorder in early adolescence could facilitate timely secondary prevention of these symptoms subsequently, helping to prevent future psychopathology.

Effectiveness of a brief psychotherapeutic intervention compared with treatment as usual for adolescent nonsuicidal self-injury: a single-centre, randomised controlled trial

Although nonsuicidal self-injury (NSSI) is a clinically significant behavior, evidence-based, specific, time-, and cost-effective treatment approaches are lacking. The aim of this study was to compare the efficacies of a brief cognitive-behavioral psychotherapy manual, the Cutting Down Programme (CDP), and treatment as usual (TAU) in the treatment of adolescent NSSI. We conducted a single-centre randomised controlled trial (RCT). Eligible participants were aged 12-17 years engaging in repetitive NSSI (at least 5 times within the past 6 months). We randomly allocated 74 participants to CDP (n = 37) or TAU (n = 37; in a 1:1 ratio). Outcome measures were administered before treatment (T0), directly after CDP or 4 months after baseline evaluation in the TAU group (T1), and another 6 months later (T2; primary endpoint). Primary outcome was a 50% reduction in NSSI frequency within the past 6 months at 10-month follow-up (T2). Regarding the primary outcome, there were no significant differences between the CDP (n = 26; 70.3%) and TAU group [n = 27; 73.0%; χ²(1) = 0.07; p = 0.797]; NSSI frequency within the past 6 months was significantly reduced at T2 [χ²(1) = 12.45; p < 0.001] with no between-group difference [χ²(1) = 0.14; p = 0.704]. However, we found a significant group x point of measurement interaction [χ²(2) = 7.78; p = 0.021] regarding NSSI within the last month indicating at T1. CDP was equally effective and achieved faster recovery compared to a significantly more intensive TAU in treating adolescent NSSI. The CDP could provide a brief and pragmatic first treatment within a stepped-care model for NSSI in routine clinical care.Clinical Trial Registration The trial was prospectively registered in the German Registry of Clinical Trials (https://www.drks.de; DRKS00003605) and is now complete.

Assessment of Personality Functioning in Adolescents With the LoPF-Q 12-18 Self-Report Questionnaire

The classification of personality disorders (PDs) is in transition. The shortcomings of the categorical PD diagnoses led to the development of the Alternative Model for Personality Disorders (AMPD) in Section III of the DSM-5 regarding a dimensional differentiation of severity of personality pathology. Impairments in personality functioning are defined as a general Criterion A for PD. Inspired by the AMPD, the LoPF-Q 12-18 was developed to assess Levels of Personality Functioning (LoPF) dimensionally in adolescents from 12 to 18 years old in self-report. The questionnaire shows good scale reliabilities, good construct validity by demonstrating a systematic variation with pathology in line with theory, and a valuable clinical utility. The results suggest that the LoPF-Q 12-18 questionnaire is a clinically useful instrument to assess personality pathology in young people and that the concept of personality functioning is useful in detecting and describing central impairments of PD pathology at an early stage of development.

Psychotic symptoms in adolescents with borderline personality disorder features

Psychotic symptoms have been found to be relatively common among adults with borderline personality disorder (BPD), and to be a marker of BPD severity, but are not recognised in daily clinical practice in these patients. This study is the first to examine the prevalence of psychotic symptoms in 15-18-year olds with BPD features. It was hypothesised that adolescents with full-threshold BPD would have significantly more psychotic symptoms than adolescents with sub-threshold BPD features, and that both these groups would have significantly more psychotic symptoms than adolescents with no BPD features. A total of 171 psychiatric outpatients, aged 15-18 years, were assessed using a structured interview for DSM-IV personality disorder and categorised into three groups: no BPD features (n = 48), sub-threshold BPD features (n = 80), and full-threshold BPD (n = 43). The groups were compared on measures of psychopathology and functioning (e.g. Youth Self Report, Symptom Check List-90-R, SOFAS). Adolescents with full-threshold BPD reported more psychotic symptoms than the sub-threshold BPD group (p < .001), and both these groups reported more psychotic symptoms than those with no BPD features (p < .001). Adolescents with full-threshold BPD reported more confusion (p < .01), paranoia (p < .001), visual hallucinations (p < .001) and strange thoughts (p < .01), than the other two groups. Psychotic symptoms predicted group membership, determined by BPD severity, after adjusting for other psychopathology and functional impairment (p < .01). Assessment of unusual perceptual experiences, paranoia or odd thoughts is highly clinically relevant in adolescents with BPD features, as these symptoms are associated with a more severe clinical presentation of BPD.
