RESUMEN
Parent-child informant discrepancies on psychopathology provide important knowledge on the parent-child relationship and the child's mental health, but mechanisms underlying parent-child informant discrepancies are largely unknown. Therefore, we investigated the relationship between attachment problems and mentalizing capacity and parent-child informant discrepancies on borderline personality disorder (BPD) severity, internalizing, and externalizing pathology in a clinical sample of 91 adolescent girls with BPD and their parents. Results showed that more attachment problems to parents and peers were related to adolescents reporting more severe BPD than parents. Adolescents who described more internalizing symptoms relative to parents, reported more parental attachment problems, but enhanced peer attachment, suggesting those adolescents who do not feel recognized by their parents might turn to their friends. When parents rated adolescents higher on externalizing behaviors, the adolescent reported more attachment problems to parents and lower mentalizing capacity, indicating that this sub-group of adolescents may reflect less about how their behavior affects others.
RESUMEN
BACKGROUND: Studies of the medium- to long-term clinical and functional course for treatment-seeking adolescents with borderline personality disorder (BPD) are lacking. This study aims to outline the psychopathological and functional status of participants, five years after being diagnosed with BPD during adolescence. METHODS: Participants were originally enrolled in a randomized clinical trial that compared mentalization-based group treatment with treatment as usual for adolescents with BPD. Semi-structured interview assessments at five-year follow-up included the Schedules for Clinical Assessment in Neuropsychiatry and the Structured Clinical Interview for DSM-5 Personality Disorders. Attention deficit hyperactivity disorder (ADHD), alcohol, substance and tobacco use, posttraumatic stress disorder (PTSD), complex PTSD, and general functioning were assessed using self-report instruments. RESULTS: 97 of the original sample of 111 participants (87%) participated. They were aged 19-23 years. The most prevalent disorders were ADHD (59%), any personality disorder (47%) of which half continued to meet criteria for BPD (24%), anxiety disorders (37%), depressive disorders (32%), PTSD or complex PTSD (20%), schizophrenia (16%), and eating disorders (13%). Only 16% did not meet criteria for any mental disorder. Approximately half of the sample were in psychological and/or psychopharmacological treatment at the time of follow-up. Their general functioning remained impaired, with 36% not engaged in education, employment or training (NEET), which is nearly four times the rate of NEET in the same age group in the general population. CONCLUSIONS: Although stability of the categorical BPD diagnosis is modest, adolescents meeting diagnostic criteria for BPD show a broad range of poor outcomes at five-year follow-up. BPD appears to be a marker of general maladjustment during adolescence and a harbinger of severe problems during the transition to young adulthood. Early intervention programs for adolescents diagnosed with BPD should focus upon a broad range of functional and psychopathological outcomes, especially social and vocational support, rather than the narrow BPD diagnosis.

INTRODUCTION: Borderline personality disorder (BPD) is a severe and prevalent psychiatric disorder. Mentalization-based therapy (MBT) is an evidence-based intervention for BPD, and several countries offer treatment programs for BPD lasting for years, which is resource demanding. No previous trial has compared short-term with long-term MBT. OBJECTIVE: The aim of the study was to assess the efficacy and safety of short-term versus long-term MBT for outpatients with BPD. METHODS: Adult outpatients (≥18 years) with subthreshold or diagnosed BPD were randomly assigned (1:1) to short-term MBT (5 months) or long-term MBT (14 months). The primary outcome was BPD symptoms assessed with the Zanarini Rating Scale for Borderline Personality Disorder. Secondary outcomes were functional impairment, quality of life, global functioning, and severe self-harm. All outcomes were primarily assessed at 16 months after randomization. This trial was prospectively registered at

BACKGROUND: Disrupted metacognition is implicated in development and maintenance of negative symptoms, but more fine-grained analyses would inform precise treatment targeting for individual negative symptoms. AIMS: This systematic review identifies and examines datasets that test whether specific metacognitive capacities distinctly influence negative symptoms. MATERIALS & METHODS: PsycINFO, EMBASE, Medline and Cochrane Library databases plus hand searching of relevant articles, journals and grey literature identified quantitative research investigating negative symptoms and metacognition in adults aged 16+ with psychosis. Authors of included articles were contacted to identify unique datasets and missing information. Data were extracted for a risk of bias assessment using the Quality in Prognostic Studies tool. RESULTS: 85 published reports met criteria and are estimated to reflect 32 distinct datasets and 1623 unique participants. The data indicated uncertainty about the relationship between summed scores of negative symptoms and domains of metacognition, with significant findings indicating correlation coefficients from 0.88 to -0.23. Only eight studies investigated the relationship between metacognition and individual negative symptoms, with mixed findings. Studies were mostly moderate-to-low risk of bias. DISCUSSION: The relationship between negative symptoms and metacognition is rarely the focus of studies reviewed here, and negative symptom scores are often summed. This approach may obscure relationships between metacognitive domains and individual negative symptoms which may be important for understanding how negative symptoms are developed and maintained. CONLCLUSION: Methodological challenges around overlapping participants, variation in aggregation of negative symptom items and types of analyses used, make a strong case for use of Individual Participant Data Meta-Analysis to further elucidate these relationships.

RESUMEN
INTRODUCTION: Prevalence rates and correlates of personality disorders (PD) are relevant to health care policy and planning. OBJECTIVES: To present normative data for self-reported ICD-11 personality disorder (PD) features including tentative cut-off scores and prevalence rates for severity levels along with psychosocial correlates. METHODS: The Personality Disorder Severity ICD-11 (PDS-ICD-11) scale and criterion measures of impairment were administered to a social-demographically stratified sample of Danish citizens (N = 8,941) of which 3,044 delivered complete data. Item-Response Theory (IRT) was employed to indicate cut-offs based on standard deviations from the latent mean. RESULTS: The unidimensionality of the PDS-ICD-11 score was supported and IRT analysis suggested norm-based thresholds at latent severity levels. Expected associations with criterion measures were found. CONCLUSION: The normative data portray ICD-11 PD features in the general population and allow for interpretation of PDS-ICD-11 scores (e.g., scores of 12, 16, and 19 may indicate mild, moderate, and severe dysfunction), which may inform health care policy and planning. A total weighted prevalence of 6.9 % of the Danish general population is estimated to have clinically significant personality dysfunction, proportionally composed of Mild (4.8 %), Moderate (1.2 %), and Severe (0.9 %) levels. Future research should corroborate these findings using relevant clinical samples and methods.

A few epidemiological studies have examined personality disorders (PDs) among children and adolescents in secondary mental health services. This study aims to describe the prevalence and incidence of PDs among children and adolescents who have attended Danish child and adolescent psychiatric services (CAPS). Using register-based data, we studied all patients under the age of 18 years who were admitted to in- and outpatient CAPS (N = 115,121) in Denmark from 2007 to 2017. A total of 4952 patients were diagnosed with a PD during the study period. The mean prevalence was 859 patients per year, and the mean incidence was 274 patients per year, including an increased incidence and prevalence of borderline, anxious, and unspecified PDs over the decade. The number of patients diagnosed with PDs increased from 700 to 851 per year, but the proportion of patients with PDs compared to all psychiatric diagnoses decreased from 4.2% to 2.8% over the study period. The PD population had an older age (14.8 years vs. 11.3 years; p < 0.001), a higher likelihood of being female (74% vs. 44%; p < 0.001), and four times more contacts with the psychiatric emergency departments than other patients with a psychiatric diagnosis. Future studies should focus on (a) implementing further epidemiological studies in different countries; (b) tracking diagnostic practices to facilitate comparisons and provide feedback for training clinicians and raising awareness; and (c) estimating trajectories of PDs, including costs within the CAPS, to facilitate informed decision-making regarding the future organization and provision of services to these children, adolescents, and their families.
RESUMEN
PURPOSE: Negative symptoms are a persistent, yet under-explored problem in psychosis. Disturbances in metacognition are a potential causal factor in negative symptom development and maintenance. This meta-analysis uses individual participant data (IPD) from existing research to assess the relationship between negative symptoms and metacognition treated as summed scores and domains. METHODS: Data sets containing individuals with negative symptoms and metacognition data, aged 16+ with psychosis, were identified according to pre-specific parameters. IPD integrity and completeness were checked and data were synthesized in two-stage meta-analyses of each negative symptoms cluster compared with metacognition in seemingly unrelated regression using restricted maximum likelihood estimation. Planned and exploratory sensitivity analyses were also conducted. RESULTS: Thirty-three eligible data sets were identified with 21 with sufficient similarity and availability to be included in meta-analyses, corresponding to 1301 participants. The strongest relationships observed were between summed scores of negative symptoms and metacognition. Metacognitive domains of self-reflectivity and understanding others' minds, and expressive negative symptoms emerged as significant in some meta-analyses. The uncertainty of several effect estimates increased significantly when controlling for covariates. CONCLUSIONS: This robust meta-analysis highlights the impact of using summed versus domain-specific scores of metacognition and negative symptoms, and relationships are not as clear-cut as once believed. Findings support arguments for further differentiation of negative symptom profiles and continued granular exploration of the relationship between metacognition and negative symptoms.

PURPOSE: Research has shown that schizophrenia augments the risk for criminal behaviour and variables both defining- and related to schizophrenia, increase criminal offending. Premeditated criminal offending is considered a severe form of criminal offending, however, very little is known about what predicts future premeditated criminal offending in schizophrenia. METHOD AND MATERIALS: In this 6-year follow-up study we explored which factors underlie future premeditated criminal behaviour in a sample of patients diagnosed with schizophrenia (N = 116). We also investigated if a specific mentalizing profile underlie part of the variance of premeditated criminal offending. RESULTS: Results showed that psychopathy underlie future premeditated crime in schizophrenia, and that a specific mentalizing profile, comprised of a dysfunctional emotional and intact cognitive mentalizing profile in relation to others, mediated parts of the relation between psychopathy and premeditated criminal offending. Finally, our results indicated that patients with schizophrenia with a specific mentalizing profile (see above) engaged in premeditated criminal behaviour earlier during the 6-year follow-up period compared to patients with other mentalizing profiles. CONCLUSIONS: Our findings suggest that mentalization should carefully be inspected in patients with schizophrenia in relation to future premeditated offending.

The Reflective Functioning Questionnaire for Youths (RFQY) is a self-report measure of reflective functioning (RF) also referred to as mentalizing. Lower levels of RF are characteristic of a wide range of mental disorders and are especially relevant in the assessment of personality pathology. The goal of the current study is to examine the psychometric properties of a Danish translation of the RFQY and to corroborate previous research on the measure's ability to differentiate between adolescents with and without borderline personality disorder (BPD) features. 889 adolescents were administered the RFQY and divided into three subsamples: a community sample (n = 644), a clinical non-personality disorder sample (n = 64), and a BPD sample (n = 181). Construct validity was examined through bivariate correlations between RFQY and a dimensional assessment of borderline personality features. Analysis of variance (ANOVA) supported the utility of the RFQY to discriminate between adolescents with and without BPD features. Moreover, a two-factor structure based on previous research of the adult version of the RFQ was examined. A series of exploratory and confirmatory factor analyses yielded a two-factor structure corroborating previous research. Implications for prevention, assessment, and treatment are discussed along with methodological limitations and suggestions for future research.

BACKGROUND: There is a dearth of studies evaluating treatment efficacy for adolescents diagnosed with borderline personality disorder. The few available randomized controlled trials that have been conducted show modest results and treatments appear to have equivalent effects. The current paper draws on (a) the lessons learnt from the last 50 years of psychotherapy research in general and (b) recent advances in mentalization-based understanding of why treatment works, which together point to the importance of following a socioecological approach in the treatment of personality problems in adolescence - a developmental period that insists on a treatment approach that goes beyond the therapist-client dyad. CASE PRESENTATION: Here, we describe such an approach, and offer a clinical case example with a young 16-year old girl diagnosed with borderline personality disorder, to illustrate what a shift toward a more socioecological approach would entail. CONCLUSIONS: The clinical impact of the socioecological approach and the potential benefits as illustrated in the current case illustration, offers a framework that justifies and allows for the expansion of service delivery for youth with borderline personality disorder beyond dyadic therapist-client work.
RESUMEN
Research supports a strong relationship between childhood maltreatment and internalizing psychopathology (e.g., anxiety and depression), and features of personality are assumed to explain some of this relationship. In this study, we proposed a model in which maladaptive traits mediate the effect of childhood trauma history on internalizing symptoms in adult individuals. A mixed sample (N = 462) composed of 142 psychiatric patients and 320 community-dwelling individuals completed the Childhood Trauma Questionnaire (CTQ), the Personality Inventory for DSM-5 (PID-5), and the Symptom Checklist (SCL-27) for internalizing psychopathology. The effect of childhood traumas explained 34% of the variance in internalizing symptoms while controlling for the influence of age and gender. The traits accounted for 78% of this effect, which was predominantly exerted through the domains of Negative Affectivity, Detachment, and Psychoticism, and specifically through the facets of Depressivity, Suspiciousness, Anxiousness, Perceptual Dysregulation, and Distractibility. This finding provides preliminary support for the proposed model indicating that the aforementioned maladaptive trait domains potentially function as mediating links by which childhood traumas are translated into internalizing symptoms in adulthood. However, these findings must be interpreted with caution due to the cross-sectional and retrospective mono-method design of this study. Clinical implications are discussed in relation to transdiagnostic treatment and the potential value of specifying trait domain specifiers in ICD-11 and DSM-5 models of personality disorders.

Borderline personality disorder (BPD) manifests in adolescents, serving as a forerunner for later dysfunctionality and life constraints. BPD is characterized by multiple difficulties in understanding the self and others, and it has been implied that intrapsychic processes of reasoning might be the primary driver of these disturbances. In this study, we examined the role of narrative identity, the dynamic and evolving story people construct about their personal pasts, presents, and futures, as a potentially important but largely overlooked aspect of temporal reasoning within the intrapsychic system of adolescents with BPD features. A total of 174 American inpatient adolescents (Mage = 15.12 years, SD = 1.52) completed self-report measures of BPD upon hospital admission. Adolescents' narrative identity (i.e., themes/future wishes of agency and communion), mentalizing, and emotion dysregulation were assessed. Results showed that narrative identity (i.e., thwarted themes of agency and communion) was associated with lower mentalizing and higher emotional dysregulation capacities, supporting narrative identity's relation to other relevant aspects of intrapsychic processes of reasoning in BPD. Regression analyses showed that both higher levels of emotion dysregulation and more thwarted narrative themes of agency (but not mentalizing) were significantly associated with BPD features. Intriguingly, narrative identity (i.e., thwarted themes of agency) showed incremental validity in accounting for features of BPD, over and above emotion dysregulation. It is concluded that disturbances related to narrative identity might be a prominent component of the intrapsychic reasoning system in BPD and should be included in future work on the topic.

This study examined prediction of various clinical outcomes in adolescents with borderline personality disorder (BPD) features. Of the 112 adolescents who participated at baseline, 97 were seen at 2-year follow-up, of which 49 (50.5%) had clinically improved, defined as a decrease in BPD pathology of minimum 12 points on the Borderline Personality Features Scale for Children (BPFS-C). Eighty-one adolescents fulfilled the diagnostic criteria for BPD and scored above clinical cutoff on the BPFS-C at baseline, of which 26 (32%) had remitted at follow-up by self-report on the BPFS-C. Results showed that adolescents with comorbid oppositional defiant disorder at baseline were less likely to have clinically improved or remitted at follow-up. Participants with increased self-reported depression and less exposure to physical abuse at baseline had increased odds of remission. Our findings suggest that more internalizing and less externalizing symptoms increase the odds of positive treatment outcome in adolescents with BPD.

The 11th revision of the International Classification of Diseases for Mortality and Morbidity Statistics (ICD-11) defines personality disorder according to personality functioning, which relates to self- and interpersonal functioning. The aim of the present study was to assess the relationship between mentalizing and personality functioning in patients with subthreshold or diagnosed borderline personality disorder. A total of 116 eligible participants were included. Mentalizing was assessed using the Mentalization Questionnaire (MZQ), personality functioning (self- and interpersonal functioning) was assessed using the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF), and borderline severity was assessed using the Zanarini Rating Scale (ZAN-BPD). Mediation analysis was employed to test if mentalizing accounted for the relationship between borderline severity and self- and interpersonal functioning. We found a significant relationship between borderline severity and both subscales of the LPFS-BF. Mentalizing fully and significantly mediated the relationship between borderline severity and interpersonal functioning. However, mentalizing only partly mediated the relationship between borderline severity and self-functioning. Controlling for the covariates gender and age did not impact the results. Mentalizing is likely to be involved in the ICD-11 model of personality functioning, especially interpersonal functioning. This could emphasize the relevance of therapy aimed at strengthening mentalizing abilities when treating personality pathology in general and people with borderline personality disorder in particular. However, self-functioning may be more nuanced, as aspects other than mentalizing also influence self-functioning. The study is explorative in nature and has methodological limitations that require caution in the interpretation and generalizability.
RESUMEN
BACKGROUND: In this paper, we outline our approach to dealing with complex social isolation by presenting a network treatment approach named Adaptive Mentalization-Based Integrative Treatment (AMBIT). METHOD: We describe the AMBIT approach, what elements it consists of, and we explain how we employed this method in the case of a 17-year-old boy referred to our child and adolescent psychiatric clinic, who isolated himself from the world. RESULTS: We emphasize in which ways the specific network approach pertinent to the AMBIT approach was helpful in this complex case. Furthermore, we describe and reveal our insecurities and doubts related to our interventions and the general treatment process and point to why the AMBIT network approach and the interventions were crucial in this case. DISCUSSION: We argue that the boy could not have been helped out of his social isolation within the conventional child and adolescent psychiatric system without engaging and establishing an integrated professional network from many sectors.

BACKGROUND: Loneliness and social avoidance are widespread and serious mental health problems. People experiencing loneliness or social avoidance have difficulties maintaining ordinary life activities and often experience profound suffering. How do we as clinicians deal with or help people out of loneliness and social avoidance? AIMS: In this paper, we introduce the issue on loneliness and social avoidance. We do so by first defining loneliness and social avoidance and outlining the impact on mental health issues of these phenomena. Next, we introduce the six papers central to the special issue along with some thoughts on how to understand therapy and treatment of social avoidance. DISCUSSION: We discuss new directions and how to move beyond more conventional therapeutic approaches to these problems.

Background: Premature termination from treatment or dropout is prevalent among patients with borderline personality disorder (BPD). To our knowledge, no studies have examined which factors predisposes dropout from therapy among adolescents with BPD. The current study examined sociodemographic, clinical and psychological predictors of dropout among adolescents who attended a one-year treatment program with mentalization-based group treatment (MBT-G).Methods: Participants were 89 female adolescent patients aged 14-18 years who attended MBT-G in a Danish child and adolescent psychiatric service and 56 matched controls who received non-manualized individual sessions (treatment as usual). Forty (45%) dropped out and 49 (55%) completed treatment in MBT-G. Pretreatment predictors included (1) sociodemographic variables such as age, schooling, relationship status and after-school job, (2) clinical measures of self-reported adolescent borderline personality features, depression, self-harm, internalizing and externalizing symptoms, and (3) psychological measures on self-reported reflective functioning (i.e., mentalizing) and attachment to peers and parents.Results: Binary logistic regression analyses revealed that lower reflective functioning was the only significant predictor of dropout in MBT-G. No sociodemographic or clinical variables predicted dropout. No significant predictors of dropout were identified among participants who received treatment as usual.Conclusions: Adolescents with BPD who report low reflective functioning are at increased risk of dropping out of MBT-G treatment but not treatment as usual. These findings highlight that clinicians need to consider level of reflective functioning among adolescents with BPD in MBT or in group therapy and adapt psychotherapy to the needs of the patient in order to reduce dropout.

The efficacy of treatment of borderline personality disorder in adolescents is an underresearched area. Although increasing research in borderline personality disorder in adolescents has emerged over the last decade there is a paucity of knowledge about how treatment is adequately designed for this group of patients. As a consequence, it is currently difficult to provide evidence-based guidelines and firm recommendations for how to design and implement borderline treatment in adolescence. In this selective review we summarize the most important research findings concerning treatment for adolescents with borderline personality disorder, including a recent mentalisation-based group treatment program. We highlight pivotal developmental obstacles for psychotherapy in adolescence and integrate these into a framework for the understanding and designing of effective treatment of borderline in adolescence.

Psychopathic tendencies are associated with difficulties in affective theory of mind (ToM), that is, in recognizing others affective mental states. In clinical and non-clinical adult samples, it has been shown that where psychopathic tendencies co-occur with schizophrenia spectrum disorders, the impairing effects of psychopathic tendencies on ToM are attenuated. These effects are yet to be examined in adolescents. We examined if the impairing effect of psychopathic tendencies on affective ToM was attenuated with increasing severity of schizotypal personality disorder (PD) in a sample of 80 incarcerated adolescent boys. We showed that the impairing effect of psychopathic tendencies on the recognition of neutral mental states, but not positive or negative mental states, was evident when the relative severity of schizotypal PD was low. However, with higher scores on both measures, we observed better performance in judging neutral mental states. The preservation of affective ToM in adolescents who show elevations in psychopathic tendencies and schizotypal PD may enable them to manipulate and extort their victims for personal gain. Our results emphasize the need to consider comorbidity in clinical case formulation when working with adolescents with conduct problems and psychopathic tendencies. More broadly, our results also suggest that the pattern of social cognitive abilities associated with co-occurring psychopathology does not always conform to an often-theorized double-dose of deficit hypothesis.
