The role of impairments in self–other distinction in borderline personality disorder: a narrative review of recent evidence

Impairments in maintaining a differentiated sense of “self” and “other” are thought to be a central feature of borderline personality disorder (BPD). However, studies directly focusing on self–other distinction (SOD) in BPD are scarce, and these findings have not yet been integrated with novel insights into the neural mechanism involved in SOD. Here, we present a narrative review of recent behavioral and neuroimaging findings focusing on impairments in SOD in BPD. Behavioral findings of SOD at the embodied level provide preliminary evidence for impairments in multisensory integration in BPD. Furthermore, both behavioral and neuroscientific data converge to suggest that SOD impairments in BPD reflect an inability to shift between self and other representations according to task demands. Research also suggests that disruptions in infant–caregiver synchrony may play a role in the development of these impairments. Based on these findings, we present a new, integrative model linking impairments in SOD to reduced neural and behavioral synchrony in BPD. The implications of these findings for future research and clinical interventions are outlined

Mentalizing as a Mechanism of Change in the Treatment of Patients With Borderline Personality Disorder: A Parallel Process Growth Modeling Approach.

Although a number of effective psychotherapeutic treatments have been developed for borderline personality disorder (BPD), little is known about the mechanisms of change explaining the effects of these treatments. There is increasing evidence that impairments in mentalizing or reflective functioning-the capacity to reflect on the internal mental states of the self and others-are a central feature of BPD. To date, no study has directly investigated the core assumption of the mentalization-based approach to BPD, that changes in this capacity are associated with treatment outcome in BPD patients. This study is the first to directly investigate this assumption in a sample of 175 patients with BPD who received long-term hospitalization-based psychodynamic treatment. Using a parallel process growth modeling approach, this study investigated whether (a) treatment was related to changes in mentalizing capacity as measured with the Reflective Functioning Questionnaire; (b) these changes could be explained by pretreatment levels of mentalizing and/or symptomatic distress; and (c) changes in mentalizing capacity over time were associated with symptomatic improvement. Mentalizing and symptomatic distress were assessed at admission, 12 and 24 weeks into treatment, and at discharge. Results showed that treatment was associated with significant decreases in mentalizing impairments (i.e., uncertainty about mental states) and symptomatic distress. Pretreatment levels of mentalizing and symptomatic distress did not predict these changes. However, improvements in mentalizing were strongly associated with the rate of decrease in symptomatic distress over time (r = .89). These findings suggest that increases in mentalizing may indeed in part explain therapeutic change in the treatment of BPD, but more research is needed to further substantiate these conclusions.

Self–other distinction and borderline personality disorder features: Evidence for egocentric and altercentric bias in a self–other facial morphing task

Self–other distinction (SOD) refers to the ability to distinguish one’s own body, actions, and mental representations from those of others. Problems with SOD are considered to be a key feature of borderline personality disorder (BPD). However, empirical studies on SOD in BPD are scarce. Here, we present a study providing preliminary support for the usefulness and validity of a self–other facial morphing task to capture the capacity for SOD in a sample of nonclinical participants high (n = 30) and low (n = 32) in BPD features. Participants had to watch a video sequence in which their own face was gradually morphed into the face of an unfamiliar other (self-to-other) or vice versa (other-to-self), requiring them to indicate at which point they judged the morph to look more like the target face than the starting face. Consistent with predictions, results showed that participants in the high-BPD group judged the morph to look like themselves for longer in the self-to-other direction (suggestive of egocentric bias), but only with a relatively more attractive target face. In the other-to-self direction, the high-BPD group had more difficulty recognizing their own face (i.e., an altercentric bias), but this time only with the relatively less attractive face. Further research is needed to replicate these findings in clinical samples, but overall they suggest that the current task might be suited to investigate SOD problems in BPD.

The construct validity of the Dutch personality inventory for DSM-5 personality disorders (PID-5) in a clinical sample

The factor structure and the convergent validity of the Personality Inventory for DSM-5 (PID-5), a self-report questionnaire designed to measure personality pathology as advocated in the fifth edition, Section III of Diagnostic and Statistical Manual of Mental Disorders (DSM-5), are already demonstrated in general population samples, but need replication in clinical samples. In 240 Flemish inpatients, we examined the factor structure of the PID-5 by means of exploratory structural equation modeling. Additionally, we investigated differences in PID-5 higher order domain scores according to gender, age and educational level, and explored convergent and discriminant validity by relating the PID-5 with the Dimensional Assessment of Personality PathologyBasic Questionnaire and by comparing PID-5 scores of inpatients with and without a DSM-IV categorical personality disorder diagnosis. Our results confirmed the original five-factor structure of the PID-5. The reliability and the convergent and discriminant validity of the PID-5 proved to be adequate. Implications for future research are discussed

Teoría y tratamiento de la depresión: ¿Hacia su integración?

Recent research has changed our view on depression in important ways. The National Institute of Mental Health (NIMH) Strategic Plan for Mood Disorders Research (NIMH, 2003) is currently the most ambitious attempt to give a new impetus to research on mood disorders, and to develop more encompassing theories that will ultimately lead to more effective treatment strategies. However, in our view, this strategic plan fails to address several important issues and recent developments in research on depression. In this article, several important points of divergence are outlined with special reference to a conference on the integration of theories and treatment strategies on depression held in Kortenberg (Belgium) on March 14, 2003.Nuestra visión sobre la depresión ha cambiado de manera considerable con la investigación reciente. El Plan estratégico para la investigación de los desórdenes del carácter del Instituto Nacional de Salud Mental (INSM, 2003) es una propuesta ambiciosa orientada a crear un nuevo ímpetu en la investigación de desórdenes del carácter por un lado, y por otro a desarrollar teorías más amplias que permitan organizar estrategias de tratamiento más efectivas. Sin embargo, desde nuestro punto de vista, el plan estratégico no ha considerado algunas investigaciones recientes ni muchos problemas altamente relevantes en el ámbito de la depresión. En el presente artículo muchos puntos de divergencia importantes se precisan con respecto a una conferencia sobre la integración de teorías y estrategias de tratamiento sobre la depresión realizada el 14 de marzo del 2003 en Kortenberg (Bélgica). &nbsp

Mechanisms of Change Through the Lens of Two-Polarities Models of Personality Development: State of the Art and New Directions

This article reviews moderators and mediators of therapeutic change through the lens of the two-polarities model of personality development. This psychodynamic model of personality development essentially proposes that personality development involves a continuous dialectic interaction between the development of the capacity for relatedness on the one hand and agency and self-definition on the other. Within this model, vulnerability for psychopathology is thought to result from an excessive emphasis on one developmental line and the defensive avoidance of the other. The two-polarities model also proposes a unified, transdiagnostic approach to therapeutic change in that it suggests that effective interventions, regardless of the brand name, lead to a reactivation of the dialectic interaction between the development of relatedness and self-definition through experiences of mutuality and understanding, as well as separation and misunderstanding in the therapeutic relationship, much as in normal personality development. We summarize research relevant to this view, and illustrate how this empirically based model of personality development and the therapeutic process may inform clinical practice. We focus specifically on recent developments within this model, which have led to a major shift in our thinking regarding the role of specific and common factors in explaining therapeutic change. We illustrate this shift in our thinking by way of a discussion of emerging research findings concerning therapeutic change in both brief and longer-term treatments across different therapeutic modalities. Limitations of the model are reviewed, and suggestions for future research are discussed

What's in a Face? Mentalizing in Borderline Personality Disorder Based on Dynamically Changing Facial Expressions

The mentalization-based approach to borderline personality disorder (BPD) argues that impairments in mentalizing are a key feature of BPD. Most previous research in this area has concentrated on potential impairments in facial emotion recognition in BPD patients. However, these studies have yielded inconsistent results, which may be attributable to methodological differences. This study aimed to address several limitations of previous studies by investigating different parameters involved in emotion recognition in BPD patients using a novel, 2-step dynamically changing facial expression paradigm, taking into account the possible influence of mood, psychotropic medication, and trauma exposure. Twenty-two BPD patients and 22 matched normal controls completed this paradigm. Parameters assessed were accuracy of emotion recognition, reaction time (RT), and level of confidence, both for first and full response and for correct and incorrect responses. Results showed (a) that BPD patients were as accurate in their first, but less accurate in their full emotion recognition than normal controls, (b) a trend for BPD patients to respond more slowly than normal controls, and (c) no significant difference in overall level of confidence between BPD patients and normal controls. Mood and psychotropic medication did not influence these results. Exposure to trauma in BPD patients, however, was negatively related to accuracy at full expression. Although further research is needed, results suggest no general emotion-recognition deficit in BPD patients using a dynamic changing facial recognition paradigm, except for a subgroup of BPD patients with marked trauma who become less accurate when they have to rely more on controlled, reflective processes

Do my emotions show or not? Problems with transparency estimation in women with borderline personality disorder features

Transparency estimation, that is, estimating the extent to which one’s mental states are observable to others, requires the simultaneous representation of the self and of others’ perspective on the self. Individuals with borderline personality disorder (BPD) have difficulty integrating multiple perspectives when mentalizing, which may be reflected in impaired transparency estimation. A total of 62 participants high and low in BPD features watched emotionally evocative video clips and estimated the transparency of their emotional experience while facial expression coding software (FaceReader) quantified their objective transparency. Individuals high in BPD features showed a larger discrepancy between estimated and objective transparency than individuals low in BPD features, showing that they both over- and underestimated their transparency. Indeed, estimated transparency positively predicted objective transparency in individuals low in BPD features, but not in individuals high in BPD features. Moreover, the ability to estimate intraindividual variability in one’s own objective transparency was moderated by self-reported arousal in the participants high in BPD features. Impairments in transparency estimation were correlated with self-report measures of borderline features, attachment, and mentalizing. In conclusion, we found that borderline features relate to a reduced capacity to estimate the extent to which one’s own emotional states are observable to others. Although replication in clinical samples of BPD patients is needed, the present study provides evidence for problems in mentalizing the (embodied) self from another person’s perspective in BPD
