A systematic review and meta-analysis of 'Systems for Social Processes' in borderline personality and substance use disorders

"Broken fragments or a breathtaking mosaic": A mixed methods study of self-reported attributes and aspirations of siblings of individuals with and without neurodevelopmental conditions

Siblings of individuals with neurodevelopmental conditions (NDCs) experience distinct challenges and have unique strengths compared to siblings of individuals without NDCs. The present study examined attributes and aspirations of siblings of individuals with and without neurodevelopmental conditions, and analyzed the association between qualitative responses and quantitative measures of growth mindset, positive and negative valence, and mental health diagnoses. A novel mixed methods thematic analysis was employed to explore the experiences of 166 siblings (75 NDC and 91 controls, aged 14-26, 66.27% female) completing an online survey as part of a larger study on sibling mental health. The overarching theme described The Process of Self-Actualization and Integration, reflecting the journey siblings undergo in seeking to understand themselves and others amidst psychological challenges. It encompassed three subthemes: Personal Growth and Identity Formation; Connection and Belonginess; and Societal Perspective and Global Consciousness. Qualitative responses were analyzed within a Research Domain Criteria (RDoC) framework, and associations between phenomenology and mental health diagnoses examined. NDC siblings had higher negative valence and lower positive valence embedded in their responses, and quantitatively lower self-reported growth mindset (i.e., beliefs about the capacity for personal growth), compared to control siblings, which correlated with self-reported mental health diagnoses. Findings suggest clinical practice may focus on optimizing self-identified strengths and offer opportunities for self-actualization of hopes and ambitions, while providing support for families to attenuate bioecological factors impacting mental health.

Social cognition in women with borderline personality disorder based on an exhaustive analysis of the Movie for Assessment of Social Cognition (MASC) categories

A significant number of borderline personality disorder (BPD) symptoms are manifested in the interpersonal context. This can be explained by the difficulties in attributing the mental states of oneself and others, which constitutes social cognition. Errors in social cognition are interrelated with the affective, cognitive, impulsive, and interpersonal areas of the person with BPD. The aims of this study was to analyze social cognition in women with BPD compared with a control group and to analyze social cognition in BPD based on BPD symptoms and its severity. To assess social cognition, we used a full range of social cognition categories provided by the Movie for the Assessment of Social Cognition (MASC): correct theory of mind (ToM); attribution of mental states (thoughts, emotions, or intentions); errors of mentalization; types of ToM; and attribution of mental states through perceptive or cognitive cues and through hot or cold emotions. The MASC has high ecological validity and has been validated in Spanish. The sample comprised 79 women, including 47 women with BPD and 32 healthy women. Worse social cognition performance was observed in women with BPD. More severe borderline symptoms were related to worse functioning in the correct ToM and to errors of no mentalization. Involvement of the cognitive area in borderline symptoms was associated with worse functioning in correct ToM and worse social cognition in cognitive areas as well as with hypermentalization. This is the first study that uses all the MASC categories and considers BPD heterogeneity and its severity to study social cognition.

The role of mentalizing in psychological interventions in adults: Systematic review and recommendations for future research

Mentalizing is the human capacity to understand actions of others and one's own behavior in terms of intentional mental states, such as feelings, wishes, goals and desires. Mentalizing is a transtheoretical and transdiagnostic concept that has been applied to understanding vulnerability to psychopathology and has attracted considerable research attention over the past decades. This paper reports on a pre-registered systematic review of evidence concerning the role of mentalizing as a moderator and mediator in psychological interventions in adults. Studies in adults were reviewed that address the following questions: (a) does pre-treatment mentalizing predict treatment outcome; (b) do changes in mentalizing across treatment predict outcome; (c) does adherence to the principles or protocol of mentalization-based treatment predict outcome; and (d) does strengthening in-session mentalizing impact the therapeutic process via improved alliance, alleviated symptoms, or improved interpersonal functioning? Results suggest that mentalizing might be a mediator of change in psychotherapy and may moderate treatment outcome. However, the relatively small number of studies (n = 33 papers based on 29 studies, totaling 3124 participants) that could be included in this review, and the heterogeneity of studies in terms of design, measures used, disorders included, and treatment modalities, precluded a formal meta-analysis and limited the ability to draw strong conclusions. Therefore, theoretical and methodological recommendations for future research to improve the quality of existing research in this area are formulated.

Borderline personality disorder: a comprehensive review of diagnosis and clinical presentation, etiology, treatment, and current controversies

Borderline personality disorder (BPD) was introduced in the DSM-III in 1980. From the DSM-III to the DSM-5, no major changes have occurred in its defining criteria. The disorder is characterized by instability of self-image, interpersonal relationships and affects. Further symptoms include impulsivity, intense anger, feelings of emptiness, strong abandonment fears, suicidal or self-mutilation behavior, and transient stress-related paranoid ideation or severe dissociative symptoms. There is evidence that BPD can be reliably diagnosed and differentiated from other mental disorders by semi-structured interviews. The disorder is associated with considerable functional impairment, intensive treatment utilization, and high societal costs. The risk of self-mutilation and suicide is high. In the general adult population, the lifetime prevalence of BPD has been reported to be from 0.7 to 2.7%, while its prevalence is about 12% in outpatient and 22% in inpatient psychiatric services. BPD is significantly associated with other mental disorders, including depressive disorders, substance use disorders, post-traumatic stress disorder, attention-deficit/hyperactivity disorder, bipolar disorder, bulimia nervosa, and other personality disorders. There is convincing evidence to suggest that the interaction between genetic factors and adverse childhood experiences plays a central role in the etiology of BPD. In spite of considerable research, the neurobiological underpinnings of the disorder remain to be clarified. Psychotherapy is the treatment of choice for BPD. Various approaches have been empirically supported in randomized controlled trials, including dialectical behavior therapy, mentalization-based therapy, transference-focused therapy, and schema therapy. No approach has proved to be superior to others. Compared to treatment as usual, psychotherapy has proved to be more efficacious, with effect sizes between 0.50 and 0.65 with regard to core BPD symptom severity. However, almost half of the patients do not respond sufficiently to psychotherapy, and further research in this area is warranted. It is not clear whether some patients may benefit more from one psychotherapeutic approach than from others. No evidence is available consistently showing that any psychoactive medication is efficacious for the core features of BPD. For discrete and severe comorbid anxiety or depressive symptoms or psychotic-like features, pharmacotherapy may be useful. Early diagnosis and treatment of BPD can reduce individual suffering and societal costs. However, more high-quality studies are required, in both adolescents and adults. This review provides a comprehensive update of the BPD diagnosis and clinical characterization, risk factors, neurobiology, cognition, and management. It also discusses the current controversies concerning the disorder, and highlights the areas in which further research is needed.

Affective and cognitive Theory of Mind in patients with alcohol use disorder: Associations with symptoms of depression, anxiety, and somatization

INTRODUCTION

Theory of Mind (ToM) is the ability to ascribe thoughts (cognitive ToM) and feelings (affective ToM) to others. Ample evidence exists for impairments of affective and cognitive ToM in individuals with alcohol use disorder (AUD); however, evidence regarding changes of these impairments during AUD treatment and their possible relationship to comorbid symptoms is ambiguous. The current study analyzed changes in ToM during treatment and tested associations with comorbid symptoms of depression, anxiety, somatization, and social functioning.

METHODS

We analyzed data from 175 individuals with AUD. The study assessed ToM and comorbid symptoms of depression, anxiety, somatization, and social functioning at the time of admission and at the time of discharge from an approximately 60 days long abstinence-oriented inpatient treatment. We assessed affective and cognitive ToM using the Movie for the Assessment of Social Cognition, a measure with high ecological validity.

RESULTS

All symptoms, total and cognitive ToM improved following treatment; however, affective ToM did not improve. Moreover, cognitive ToM at the beginning of treatment was associated with improved symptoms of depression and somatization, while affective ToM was not.

CONCLUSIONS

Our study shows improvements in total and cognitive ToM as well as symptoms of depression, anxiety, somatization, and social functioning following long-term treatment. Furthermore, cognitive ToM was related to improvements in comorbid symptoms. This finding suggests that ToM may be an important treatment target in patients with AUD.

Combining novel trait and neurocognitive frameworks to parse heterogeneity in borderline personality disorder

OBJECTIVE

Borderline Personality Disorder (BPD) diagnosis comprises several constellations of trait, neurocognitive, and psychosocial alterations. Dimensional models of psychopathology provide new opportunities to parse heterogeneity and create a stronger interface between individual characterization and psychosocial outcomes. However, dimensional models have focused on either traits or neurocognitive features, lacking integration to capture the multifaceted nature of BPD.

METHOD

We assessed 100 participants with BPD using a combination of tools stemming from trait (Alternative Model for Personality Disorders) and neurocognitive models (Research Domain Criteria; RDoC) to examine if trait-derived subgroups display distinctive social-processing and psychosocial profiles. We used two complementary analytical approaches: person-centered (k-means clustering) and construct-based (multiple factor analysis).

RESULTS

Our person-centered approach identified four subgroups with separable internalizing, detached, externalizing, and low psychopathology trait profiles. These profiles revealed distinctive patterns of affiliation, emotion recognition and mentalization performance in RDoC tasks, and psychosocial measures of quality of life and social connectedness. RDoC-based measures showed close construct proximity with negative affectivity, disinhibition, and antagonism trait domains, relative to the detachment domain, which had close proximity with self-knowledge.

CONCLUSIONS

Altogether, findings support consilience between trait-based and neurobiological frameworks and suggest that trait models are useful to parse BPD heterogeneity leading to unique social functioning profiles.

A Model of Trust Processes in Borderline Personality Disorder: A Systematic Review

PURPOSE OF REVIEW

Unstable relationships are a core feature of borderline personality disorder (BPD). Impairments in trust processes (i.e., appraisal and learning regarding others' trustworthiness) can subserve interpersonal problems associated with BPD, but the determinants, mechanisms, consequences, and variations in trust impairments among individuals with BPD remain poorly characterized. Thus, a better understanding of such impairments could help target interventions that address the interpersonal problems of individuals with BPD beyond emotion dysregulation, impulsivity, and aggression.

RECENT FINDINGS

We conducted a pre-registered systematic review of empirical studies on trust processes and BPD features (k = 29). Results are organized around a heuristic model of trust processes in BPD comprising the following stages: developmental factors, prior beliefs and dispositions, situation perception, emotional states, trust appraisal, behavioral manifestations, and trust learning. Based on the synthesis of the findings, we recommended directions for future research and clinical assessment and intervention, such as managing trust during the early stages of therapy and considering improvements in trust processes as a central mechanism of change in treating individuals with BPD.

The Co-occurrence of Personality Disorders and Substance Use Disorders

PURPOSE OF REVIEW

Despite significant negative outcomes, the co-occurrence of personality disorders (PDs) and substance use disorders (SUDs) continues to be underrecognized, and the mechanisms contributing to this co-occurrence remain unclear. This review summarizes recent work on PD-SUD co-occurrence, with a focus on borderline and antisocial PDs, general substance use patterns among those with PDs, and the association of personality traits with SUDs.

RECENT FINDINGS

The prevalence of co-occurring PD-SUD is generally high, with estimates ranging depending on the type of PD and SUD, the population assessed, and the sampling methods and measures used. Current theoretical explanations for co-occurrence include shared etiology and predisposition models, with research highlighting the importance of transactional processes. Potential underlying mechanisms include personality traits and transdiagnostic characteristics. Recent research has increased focus on substances besides alcohol, dimensional models of personality pathology, and transactional explanations of co-occurrence, but more research is needed to disentangle the nuanced PD-SUD relationship.

Interpersonal Trust and Borderline Personality Disorder: Insights From Clinical Practice and Research: Introduction

Individuals suffering from borderline personality disorder (BPD) show a pervasive sense that others cannot be trusted, are vulnerable to negative therapeutic reactions, and can oscillate between idealized and persecutory interactions with others. These trust processing impairments impact both the immediate and wider social milieu of individuals with BPD, including therapist-patient interactions. Recently, research started unraveling the social-cognitive mechanisms of these impairments in BPD. In this Special Issue, we attempt to close the gap between research findings and clinical theories on trust processing impairment in BPD. The first section includes five original studies on trust processing in BPD. The second section includes five articulations of trust processing impairment as a treatment target in evidence-based treatments for BPD and as an indispensable "common factor" in the treatment of BPD. These cutting-edge research and clinical contributions advance a potential integrative, clinical science framework for conceptualizing and intervening effectively with those who struggle with BPD.

Contrasting social knowledge and theory of mind patterns in adults with personality disorders, schizophrenia spectrum disorders, and healthy controls

INTRODUCTION

Personality disorders (PD) and schizophrenia spectrum disorders (SSD) are distinct conditions displaying common symptoms, like impairments in social cognition, that make them hard to distinguish, especially in severe cases. To date, few studies have compared theory of mind skills in these two disorders, and none have compared social knowledge skills. This study aims to compare the social cognitive abilities of patients with these conditions.

METHOD

Non-parametric analyses of covariance were used to compare severe PD patients (n = 37), SSD patients (n = 44), and healthy controls (HC; n = 49) on the Social Knowledge Test and two measures of theory of mind: the Reading the Mind in the Eyes Test and the Combined Stories Test, which incorporates items from various widely used tests.

RESULTS

While no significant group differences were found on the Social Knowledge Test, SSD patients performed lower than the HC group on both theory of mind tests. PD patients only had lower performance than the HC group on specific items from the Combined Stories Test.

CONCLUSIONS

PD and SSD patients demonstrated distinctive patterns of social cognitive impairments, with items of greater complexity or with an affective orientation being the most discriminant for PD.

Psychopathology and Theory of Mind in patients with personality disorders

OBJECTIVE

People with mental disorders frequently suffer from deficits in the ability to infer other's mental states (Theory of Mind; ToM). Individuals with borderline personality disorder (BPD) show ToM deficits characterized by exceeding ToM (over-attributions of mental states). The present study analyzed associations between ToM, BPD severity, and depression severity in patients with BPD and other personality disorders.

METHOD

We analyzed ToM abilities in 128 patients with BPD and 82 patients with 'mixed and other personality disorders' (MOPD). MOPD are diagnosed if symptoms of multiple personality disorders are present without any set of symptoms being dominant enough to allow a specific diagnosis. We used the movies for the assessment of social cognition (MASC) to measure ToM abilities, the Patient Health Questionnaire (PHQ-9) to assess severity of depression and the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD) to assess the severity of BPD symptoms.

RESULTS

Both symptoms of BPD and depression were associated with exceeding ToM in separate regressions. Using a stepwise regression, only the association of depression severity with exceeding ToM was reliable. Patients with BPD and MOPD did not differ in exceeding ToM. Age was most reliably associated with ToM.

CONCLUSION

The results imply that exceeding ToM is associated with general psychopathology instead of BPD-symptoms in specific. Patients with MOPD show deficits similar to BPD patients.

Cognitive training and remediation interventions for substance use disorders: a Delphi consensus study

AIMS

Substance use disorders (SUD) are associated with cognitive deficits that are not always addressed in current treatments, and this hampers recovery. Cognitive training and remediation interventions are well suited to fill the gap for managing cognitive deficits in SUD. We aimed to reach consensus on recommendations for developing and applying these interventions.

DESIGN, SETTING AND PARTICIPANTS

We used a Delphi approach with two sequential phases: survey development and iterative surveying of experts. This was an on-line study. During survey development, we engaged a group of 15 experts from a working group of the International Society of Addiction Medicine (Steering Committee). During the surveying process, we engaged a larger pool of experts (n = 54) identified via recommendations from the Steering Committee and a systematic review.

MEASUREMENTS

Survey with 67 items covering four key areas of intervention development: targets, intervention approaches, active ingredients and modes of delivery.

FINDINGS

Across two iterative rounds (98% retention rate), the experts reached a consensus on 50 items including: (i) implicit biases, positive affect, arousal, executive functions and social processing as key targets of interventions; (ii) cognitive bias modification, contingency management, emotion regulation training and cognitive remediation as preferred approaches; (iii) practice, feedback, difficulty-titration, bias modification, goal-setting, strategy learning and meta-awareness as active ingredients; and (iv) both addiction treatment work-force and specialized neuropsychologists facilitating delivery, together with novel digital-based delivery modalities.

CONCLUSIONS

Expert recommendations on cognitive training and remediation for substance use disorders highlight the relevance of targeting implicit biases, reward, emotion regulation and higher-order cognitive skills via well-validated intervention approaches qualified with mechanistic techniques and flexible delivery options.

How selves differ within and across cognitive domains: self-prioritisation, self-concept, and psychiatric traits

Background

How we build and maintain representations of ourselves involves both explicit features which are consciously accessible on reflection and implicit processes which are not, such as attentional biases. Understanding relations between different ways of measuring self-cognition both within and across such cognitive domains is important for understanding how selves may differ from one another, and whether self-cognition is best understood as largely uni-dimensional or more multi-dimensional. Further, uncovering this structure should inform research around how self-cognition relates to psychiatric and psychological conditions. This study explores the relations between different constructs of self-cognition and how variability within them relates to psychiatric traits.

Methods

Our final dataset includes within-subject (n = 288, general population) measures of explicit self-concept (using both the Self Concept Clarity Scale and Self Concept and Identity Measure), implicit self-prioritisation in a shape-label matching task (for both reaction time and sensitivity) and measurement of traits for five psychiatric conditions (autism, borderline personality disorder, schizophrenia, depression and anxiety). We first test whether self-cognitive measures within and across domains are correlated within individuals. We then test whether these dimensions of self-cognition support a binary distinction between psychiatric conditions that either are or are not characterised in terms of self, or whether they support self-cognition as transdiagnostically predictive of the traits associated with psychiatric conditions. To do this we run a series of planned correlations, regressions, and direct correlation comparison statistics.

Results

Results show that implicit self-prioritisation measures were not correlated with the explicit self-concept measures nor the psychiatric trait measures. In contrast, all the psychiatric traits scores were predicted, to varying degrees, by poorer explicit self-concept quality. Specifically, borderline personality disorder traits were significantly more strongly associated with composite explicit self-concept measures than any of depression, anxiety, or autism traits scores were.

Conclusions

Our results suggest that selves can differ considerably, along different cognitive dimensions. Further, our results show that self-cognition may be a promising feature to include in future dimensional characterisations of psychiatric conditions, but care should be taken to choose relevant self-cognitive domains.

Can we rewire criminal mind via non-invasive brain stimulation of prefrontal cortex? Insights from clinical, forensic and social cognition studies

Non-compliance with social and legal norms and regulations represents a high burden for society. Social cognition deficits are frequently called into question to explain criminal violence and rule violations in individuals diagnosed with antisocial personality disorder (APD), borderline personality disorder (BPD), and psychopathy. In this article, we proposed to consider the potential benefits of non-invasive brain stimulation (NIBS) to rehabilitate forensic population. We focused on the effects of NIBS of the prefrontal cortex, which is central in social cognition, in modulating aggression and impulsivity in clinical disorders, as well as in forensic population. We also addressed the effect of NIBS on empathy, and theory of mind in non-clinical and/or prison population. The reviewed data provide promising evidence on the beneficial effect of NIBS on aggression/impulsivity dyscontrol and social cognitive functions, suggesting its relevance in promoting reintegration of criminals into society.

Bifocalism is in the eye of the beholder: Social learning as a developmental response to the accuracy of others' mentalizing

This commentary argues the case for developmental psychopathology in understanding social learning. Informed by work on “epistemic disruption,” we have described difficulties with social learning associated with many forms of psychopathology. Epistemic disruption manifests in an inability to move between innovation and conformity, and arises from poor mentalizing, which generates difficulties in identifying social cues that trigger the correct stance.

The Role of the Posterior Cerebellum in Dysfunctional Social Sequencing

Recent advances in social neuroscience have highlighted the critical role of the cerebellum in social cognition, and especially the posterior cerebellum. Studies have supported the view that the posterior cerebellum builds internal action models of our social interactions to predict how other people's actions will be executed and what our most likely responses are to these actions. This mechanism allows to better anticipate action sequences during social interactions in an automatic and intuitive way and to fine-tune these anticipations, making it easier to understand other's social behaviors and mental states (e.g., beliefs, intentions, traits). In this paper, we argue that the central role of the posterior cerebellum in identifying and automatizing social action sequencing provides a fruitful starting point for investigating social dysfunctions in a variety of clinical pathologies, such as autism, obsessive-compulsive and bipolar disorder, depression, and addiction. Our key hypothesis is that dysfunctions of the posterior cerebellum lead to under- or overuse of inflexible social routines and lack of plasticity for learning new, more adaptive, social automatisms. We briefly review past research supporting this view and propose a program of research to test our hypothesis. This approach might alleviate a variety of mental problems of individuals who suffer from inflexible automatizations that stand in the way of adjustable and intuitive social behavior, by increasing posterior cerebellar plasticity using noninvasive neurostimulation or neuro-guided training programs.
