Emotion processing in borderline personality disorders

Borderline personality disorder is associated with lower confidence in perception of emotional body movements

Much recent research has shown that personality disorders are associated with an altered emotion perception. Whereas most of this research was conducted with stimuli such as faces, the present study examined possible differences in the perception of emotions expressed via body language and body movements. 30 patients with borderline personality disorder (BPD) and 30 non-patients observed video scenes of emotional human interactions conveyed by point–light displays, rated the depicted valence, and judged their confidence in this rating. Patients with BPD showed no altered emotion perception (i.e., no biased perception in either a negative or a positive direction). They did not perceive and evaluate depicted emotions as being more extreme than healthy controls. However, patients with BPD showed less confidence in their perception of depicted emotions, especially when these were difficult to identify. The findings extend insights on altered emotion perception in persons with BPD to include the field of body movements.

Emotional reactivity to social rejection and negative evaluation among persons with borderline personality features

The present study examined the emotional reactivity of persons with heightened borderline personality (BP) features to social rejection and negative evaluation in the laboratory. Individuals with high levels of BP features (n = 30) and controls with low levels of BP features (n = 44) were randomly assigned to a condition involving negative evaluation based on writing (negative evaluation/academic), or a condition involving negative evaluation based on personal characteristics as well as social rejection (negative evaluation/social rejection). Hypothesis 1 was that high-BP individuals, but not low-BP controls, would show greater emotional reactivity to the negative evaluation/social rejection stressor, compared with the negative evaluation/academic (writing) stressor. Hypothesis 2 was that high-BP individuals would specifically show greater reactivity of shame- and anger-related emotions to the negative evaluation/social rejection stressor compared with the negative evaluation/academic stressor. Findings indicated that high-BP individuals showed heightened emotional reactivity to the social rejection stressor but not to the negative evaluation stressor, but the opposite pattern occurred for controls. In addition, there was evidence for heightened reactivity of irritability, distress, and shame for the high-BP group, specifically in the social rejection condition.

Construct Validity of the Five Factor Borderline Inventory

The Five Factor Borderline Inventory (FFBI) is a new self-report measure developed to assess traits of borderline personality disorder (BPD) from the perspective of the Five Factor Model of general personality. The current study sought to first replicate initial validity findings for the FFBI and then to further validate the FFBI with predispositional risk factors of the biosocial theory of BPD and with commonly associated features of BPD (e.g., depression, low self-esteem) utilizing two samples of young adults ( N = 87; 85) who have engaged in nonsuicidal self-injury. The FFBI showed strong convergent and discriminant validity across two measures of the Five Factor Model and also correlated strongly with measures of impulsivity, emotion dysregulation, and BPD. The FFBI also related to two measures of early childhood emotional vulnerability and parental invalidation and measures of depression, anxiety, and self-esteem. Overall, the results provide support for the FFBI as a measure of BPD.

Dissociation of explicit and implicit measures of the behavioral inhibition and activation system in borderline personality disorder

Patients with borderline personality disorder (BPD) suffer from various impairments in emotional functioning such as affective instability, inappropriate anger and unstable relationships. These deficits may influence two fundamental motivational systems, the behavioral inhibition system (BIS) and behavioral activation system (BAS). To investigate behavioral intentions and possible impairments in BPD we applied an implicit joystick task to measure implicit behavioral tendencies in response to facial expressions (happiness, sadness, anger, fear and neutral) in 25 patients with BPD and matched 25 healthy controls (HC). Additionally, we evaluated explicit approach and avoidance reactions to these social stimuli, emotion recognition abilities and subjective behavioral ratings. Our data analysis suggests that, although BPD patients accurately identified facial emotional expressions and reacted to them similarly as HC in the joystick task, they had significantly stronger avoidance tendencies in the rating task, especially for happiness and fear. On top of this they exhibited increased BIS sensitivity and decreased BAS sensitivity in the self-report measures. Possible influences are maladaptive cognitive schemas, high negative affect, insecure attachment style and a negative evaluation bias. The observed dysfunctional avoidance ratings may influence the appraisal of socially relevant stimuli and therefore adds further knowledge on social interaction problems in BPD.

Emotionsregulation: Überblick und kritische Reflexion des aktuellen Forschungsstandes

Die Forschung zum Thema Emotionsregulation erfreut sich auch im Bereich der Klinischen Psychologie einer zunehmenden Beliebtheit. Allerdings stellt sich die Frage, inwieweit die Popularität des Konstrukts im Einklang mit dessen Validität und tatsächlicher heuristischer Fruchtbarkeit steht. Vor diesem Hintergrund ist es Ziel der vorliegenden Arbeit, einen aktuellen Überblick über Konzeptualisierungen, Erfassungsmethoden, Befunde zum Zusammenhang mit psychischen Störungen sowie Möglichkeiten der therapeutischen Nutzung des Konzeptes Emotionsregulation zu geben. Aufbauend auf einer kritischen Reflexion bisheriger Konzepte, Vorgehensweisen und Befunde werden Vorschläge gemacht, wie die Validität und die heuristische Fruchtbarkeit des Emotionsregulationsparadigmas weiter gefördert werden können.

Facial emotion recognition in adolescents with personality pathology

It has been argued that a heightened emotional sensitivity interferes with the cognitive processing of facial emotion recognition and may explain the intensified emotional reactions to external emotional stimuli of adults with personality pathology, such as borderline personality disorder (BPD). This study examines if and how deviations in facial emotion recognition also occur in adolescents with personality pathology. Forty-two adolescents with personality pathology, 111 healthy adolescents and 28 psychiatric adolescents without personality pathology completed the Emotion Recognition Task, measuring their accuracy and sensitivity in recognizing positive and negative emotion expressions presented in several, morphed, expression intensities. Adolescents with personality pathology showed an enhanced recognition accuracy of facial emotion expressions compared to healthy adolescents and clients with various Axis-I psychiatric diagnoses. They were also more sensitive to less intensive expressions of emotions than clients with various Axis-I psychiatric diagnoses, but not more than healthy adolescents. As has been shown in research on adults with BPD, adolescents with personality pathology show enhanced facial emotion recognition.

Impulsivity dimensions, emotion dysregulation, and borderline personality disorder features among Italian nonclinical adolescents

BACKGROUND

Contemporary theorists have suggested that impulsivity and emotion dysregulation are two of the core features of BPD. The aim of this study was to evaluate the relationships between Borderline Personality Disorder (BPD) features, impulsivity, and emotion dysregulation in adolescence.

METHODS

1,157 nonclinical adolescents were administered the Borderline Personality Inventory, following which three groups of adolescents with high (high-BPD; n = 29), average (average-BPD; n = 31), and low (low-BPD; n = 31) levels of BPD features were selected. Participants in these three groups were administered the UPPS-P Impulsive Behavior Scale (UPPS-P) and the Difficulties in Emotion Regulation Scale (DERS).

RESULTS

UPPS-P Negative and Positive Urgency scales, as well as the DERS total score, significantly discriminated high-BPD adolescents from both other groups. The differences in UPPS-P Negative and Positive Urgency between high-BPD adolescents and both control groups remained significant when partialing out the variance associated with the DERS; However, when partialing out the variance associated with Positive and Negative Urgency, high-BPD adolescents reported significantly higher DERS scores than only the low-BPD control group (and not the average-BPD group). Finally, although the differences in Positive Urgency between high-BPD adolescents and both control groups remained significant when partialing out the variance associated with Negative Urgency, the between group differences in Negative Urgency did not remain significant when controlling for the variance associated with Positive Urgency.

CONCLUSIONS

These findings highlight the relevance of both emotion dysregulation and two dimensions of impulsivity (negative and positive urgency) to BPD features in adolescence, providing evidence for a unique association between BPD features and Positive Urgency in particular. These findings add to the literature in this area, suggesting that the tendency to act rashly in the context of intense positive affect may have unique relevance to BPD features in adolescence.

Enhanced sensitivity and response bias for male anger in women with borderline personality disorder

Interpersonal difficulties, which are characteristic of Borderline personality disorder (BPD), may be related to problems with social cognition. We explored facial emotion recognition in 44 women (15 with BPD, 15 healthy controls, and 14 with a history of childhood trauma but no BPD) examining the role of BPD and abuse history in the ability to detect fearful, angry and happy cues in emotional faces. In Task 1, participants viewed pictures of morphed faces containing different percentages of specific emotions and reported the emotion they saw. In Task 2, participants were asked to increase the intensity of a specific emotion on an initially neutral face until they could detect that emotion in the face. Across both tasks, BPD predicted the earlier detection of anger in male faces. BPD symptoms also predicted the misidentification of anger in male faces containing no anger cues. Although participants with BPD were slower to recognize happiness in male faces, their overall ability to recognize happiness was unimpaired. Abuse history did predict problems with happiness recognition. Finally, recognition of fear was unrelated to abuse history and BPD. Findings suggest that BPD is associated with a bias toward seeing anger in males and that this is independent of abuse history.

Emotion regulation strategies in bipolar II disorder and borderline personality disorder: differences and relationships with perceived parental style

BACKGROUND

Bipolar II disorder (BP II) and Borderline Personality Disorder (BPD) share common features and can be difficult to differentiate, contributing to misdiagnosis and inappropriate treatment. Research contrasting phenomenological features of both conditions is limited. The current study sought to identify differences in emotion regulation strategies in BP II and BPD in addition to examining relationships with perceived parental style.

METHOD

Participants were recruited from a variety of outpatient and community settings. Eligible participants required a clinical diagnosis of BP II or BPD, subsequently confirmed via structured diagnostic interviews assessing DSM-IV criteria. Participants completed a series of self-reported questionnaires assessing emotion regulation strategies and perceived parental style.

RESULTS

The sample comprised 48 (n=24 BP II and n=24 BPD) age and gender-matched participants. Those with BPD were significantly more likely to use maladaptive emotion regulation strategies, less likely to use adaptive emotion regulation strategies, and scored significantly higher on the majority of (perceived) dysfunctional parenting sub-scales than participants with BP II. Dysfunctional parenting experiences were related to maladaptive emotion regulation strategies in participants with BP II and BPD, however differential associations were observed across groups.

LIMITATIONS

Relatively small sample sizes; lack of a healthy control comparator group; lack of statistical control for differing sociodemographic and clinical characteristics, medication and psychological treatments; no assessment of state or trait anxiety; over-representation of females in both groups limiting generalisability of results; and reliance on self-report measures.

CONCLUSIONS

Differences in emotion regulation strategies and perceived parental style provide some support for the validity of distinguishing BP II and BPD. Development of intervention strategies targeting the differing forms of emotion regulatory pathology in these groups may be warranted.

Empathy in narcissistic personality disorder: from clinical and empirical perspectives

Narcissistic personality disorder (NPD) is associated with an assortment of characteristics that undermine interpersonal functioning. A lack of empathy is often cited as the primary distinguishing feature of NPD. However, clinical presentations of NPD suggest that empathy is not simply deficient in these individuals, but dysfunctional and subject to a diverse set of motivational and situational factors. Consistent with this presentation, research illustrates that empathy is multidimensional, involving 2 distinct emotional and cognitive processes associated with a capacity to respectively understand and respond to others' mental and affective states. The goal of this practice review is to bridge the gap between our psychobiological understanding of empathy and its clinical manifestations in NPD. We present 3 case studies highlighting the variability in empathic functioning in people with NPD. Additionally, we summarize the literature on empathy and NPD, which largely associates this disorder with deficient emotional empathy, and dysfunctional rather than deficient cognitive empathy. Because this research is limited, we also present empathy-based findings for related syndromes (borderline and psychopathy). Given the complexity of narcissism and empathy, we propose that multiple relationships can exist between these constructs. Ultimately, by recognizing the multifaceted relationship between empathy and narcissism, and moving away from an all or nothing belief that those with NPD simply lack empathy, therapists may better understand narcissistic patients' behavior and motivational structure.

Interpersonal functioning in borderline personality disorder: a systematic review of behavioral and laboratory-based assessments

It is widely accepted that interpersonal problems are a central area of difficulty for those with borderline personality disorder (BPD). However, empirical elucidation of the specific behaviors, or patterns of behaviors, characterizing interpersonal dysfunction or dissatisfaction with relationships in BPD is limited. In this paper, we review the literature on interpersonal functioning of individuals with BPD by focusing on studies that include some assessment of interpersonal functioning that is not solely self-report; that is, studies with either behavioral laboratory tasks or manipulation of interpersonal stimuli in a controlled laboratory setting were included. First, we review the literature relevant to social cognition, including perceptual biases, Theory of Mind/empathy, and social problem-solving. Second, we discuss research that assesses reactivity to interpersonal stressors and interpersonal aggression in BPD. Next, we review the literature on trust and cooperation among individuals with BPD and controls. Last, we discuss the behavior of mothers with BPD in interactions with their infants. In conclusion, we specify areas of difficulty that are consistently identified as characterizing the interpersonal behaviors of those with BPD and the relevant implications. We also discuss the difficulties in synthesizing this body of literature and suggest areas for future research.

Emotion: empirical contribution. Maternal borderline personality pathology and infant emotion regulation: examining the influence of maternal emotion-related difficulties and infant attachment

Evidence suggests that maternal borderline personality (BP) pathology increases offspring risk. This study examined the relations between maternal BP pathology and related emotional dysfunction (including emotion regulation [ER] difficulties and emotional intensity/reactivity) and infant ER difficulties. Specifically, we examined both self-focused and caregiver-focused ER behaviors and the modulation of emotional expressions (one indicator of ER in young children) in response to fear- and anger-eliciting stimuli among 101 infants (12 to 23 months old) of mothers with and without clinically relevant BP pathology. The authors also examined the moderating role of mother-infant attachment. Findings of a series of multiple regression mediation analyses revealed an indirect effect of maternal BP pathology on infant ER difficulties through maternal emotional dysfunction, with maternal ER difficulties facilitating an indirect effect of maternal BP pathology on expressivity-related indicators of infant ER difficulties and maternal emotional intensity/reactivity linking maternal BP pathology to lower self-focused ER for infants in insecure-resistant attachment relationships.

Set shifting and reversal learning in borderline personality disorder

BACKGROUND

People with BPD have been shown in some studies to have structural deficits in regions of the prefrontal cortex. A sensitive test of prefrontal cortex function is the intra-dimensional/extra-dimensional (IDED) set shifting task. This study sought to examine whether people with BPD demonstrate impaired performances on extra-dimensional shift (EDS) and reversal learning aspects of this task similar to those seen in conditions such as schizophrenia and bipolar affective disorder.

METHOD

Twenty subjects with BPD and 21 healthy control subjects were administered the IDED task from the Cambridge Neuropsychological Test Automated Battery cognitive test battery. EDS and reversal learning errors were compared between the groups using repeated measures ANOVAs.

RESULTS

There was no significant difference between the BPD and control participants in EDS or reversal learning on the IDED task or in stage of the task completed. There was a medium effect size difference (Cohen's d = 0.4) for simple reversal learning and small effect sizes for reversal learning (Cohen' d = 0.17) and IDED shift stages (Cohen's d = 0.2 and -0.3 respectively).

CONCLUSIONS

Participants with BPD in this study did not show statistically significant deficits in EDS or reversal learning, although small to medium effect sizes were found. These findings distinguish them from sufferers of schizophrenia and bipolar affective disorder and are in keeping with the idea that BPD is a distinct condition with discrete neuropathological processes.

Borderline features are associated with inaccurate trait self-estimations

BACKGROUND

Many treatments for Borderline Personality Disorder (BPD) are based upon the hypothesis that gross distortion in perceptions and attributions related to self and others represent a core mechanism for the enduring difficulties displayed by such patients. However, available experimental evidence of such distortions provides equivocal results, with some studies suggesting that BPD is related to inaccuracy in such perceptions and others indicative of enhanced accuracy in some judgments. The current study uses a novel methodology to explore whether individuals with BPD features are less accurate in estimating their levels of universal personality characteristics as compared to community norms.

METHOD

One hundred and four students received course instruction on the Five Factor Model of personality, and then were asked to estimate their levels of these five traits relative to community norms. They then completed the NEO-Five Factor Inventory and the Personality Assessment Inventory-Borderline Features scale (PAI-BOR). Accuracy of estimates was calculated by computing squared differences between self-estimated trait levels and norm-referenced standardized scores in the NEO-FFI.

RESULTS

There was a moderately strong relationship between PAI-BOR score and inaccuracy of trait level estimates. In particular, high BOR individuals dramatically overestimated their levels of Agreeableness and Conscientiousness, estimating themselves to be slightly above average on each of these characteristics but actually scoring well below average on both. The accuracy of estimates of levels of Neuroticism were unrelated to BOR scores, despite the fact that BOR scores were highly correlated with Neuroticism.

CONCLUSIONS

These findings support the hypothesis that a key feature of BPD involves marked perceptual distortions of various aspects of self in relationship to others. However, the results also indicate that this is not a global perceptual deficit, as high BOR scorers accurately estimated that their emotional responsiveness was well above average. However, such individuals appear to have limited insight into their relative disadvantages in the capacity for cooperative relationships, or their limited ability to approach life in a planful and non-impulsive manner. Such results suggest important targets for treatments addressing problems in self-other representations.

Facial reactions during emotion recognition in borderline personality disorder: a facial electromyography study

BACKGROUND

Previous studies have suggested increased sensitivity for emotional facial expressions and subtle impairments in emotion recognition from facial expressions in borderline personality disorder (BPD). It has been proposed that facial mimicry contributes to emotion recognition of and emotional response to facial expressions. This study investigated whether BPD patients differ in facial reactions, emotion recognition and their subjective emotional response to faces showing different emotional expressions.

METHOD

Twenty-eight female BPD patients and 28 healthy controls underwent a facial recognition task with dynamic facial pictures while facial muscle activity (occipitofrontalis, corrugator supercilii, levator labii superioris, zygomaticus major and orbicularis oculi) was recorded. Furthermore, participants rated the emotional intensity of the presented faces and the intensity of their subjective feeling of this emotion.

RESULTS

Compared to controls, BPD patients showed enhanced responses of the corrugator supercilii muscle in response to angry, sad and disgusted facial expressions, and attenuated responses of the levator labii superioris in response to happy and surprised faces. There were no overall group differences regarding emotion recognition performance or intensity ratings.

CONCLUSION

These results do not support the view that facial recognition in BPD is impaired or that there is a general hypersensitivity to the emotional state of others. Instead, they suggest a negativity bias in BPD, expressed by reduced facial responding to positive social signals and increased facial responding to negative social signals. This is a pattern of facial reactions that might contribute to the difficulties in social interactions frequently reported by patients with this disorder.

Social judgement in borderline personality disorder

Background

Borderline personality disorder (BPD) is a common and serious mental illness, associated with a high risk of suicide and self harm. Those with a diagnosis of BPD often display difficulties with social interaction and struggle to form and maintain interpersonal relationships. Here we investigated the ability of participants with BPD to make social inferences from faces.

Method

20 participants with BPD and 21 healthy controls were shown a series of faces and asked to judge these according to one of six characteristics (age, distinctiveness, attractiveness, intelligence, approachability, trustworthiness). The number and direction of errors made (compared to population norms) were recorded for analysis.

Results

Participants with a diagnosis of BPD displayed significant impairments in making judgements from faces. In particular, the BPD Group judged faces as less approachable and less trustworthy than controls. Furthermore, within the BPD Group there was a correlation between scores on the Childhood Trauma Questionnaire (CTQ) and bias towards judging faces as unapproachable.

Conclusion

Individuals with a diagnosis of BPD have difficulty making appropriate social judgements about others from their faces. Judging more faces as unapproachable and untrustworthy indicates that this group may have a heightened sensitivity to perceiving potential threat, and this should be considered in clinical management and treatment.

An expanded approach to batterer intervention programs incorporating neuroscience research

Batterer Intervention Programs have been critiqued for failing to incorporate treatment strategies that are supported by neurobiology research. This article reviews findings that have informed the treatment of disorders that are strongly represented among perpetrators of intimate violence, such as addiction, posttraumatic stress disorder, mood, anxiety, and personality disorders. The article argues for an expanded perspective that recognizes the relationships among childhood trauma, emotional regulation impairment, and intimate partner violence. Recommendations and ways to draw on emerging knowledge to invigorate existing programs are provided.

Emotion differentiation as a protective factor against nonsuicidal self-injury in borderline personality disorder

Evidence that nonsuicidal self-injury (NSSI) serves a maladaptive emotion regulation function in borderline personality disorder (BPD) has drawn attention to processes that may increase risk for NSSI by exacerbating negative emotion, such as rumination. However, more adaptive forms of emotion processing, including differentiating broad emotional experiences into nuanced emotion categories, might serve as a protective factor against NSSI. Using an experience-sampling diary, the present study tested whether differentiation of negative emotion was associated with lower frequency of NSSI acts and urges in 38 individuals with BPD who reported histories of NSSI. Participants completed a dispositional measure of rumination and a 21-day experience-sampling diary, which yielded an index of negative emotion differentiation and frequency of NSSI acts and urges. A significant rumination by negative emotion differentiation interaction revealed that rumination predicted higher rates of NSSI acts and urges in participants with difficulty differentiating their negative emotions. The results extend research on emotion differentiation into the clinical literature and provide empirical support for clinical theories that suggest emotion identification and labeling underlie strategies for adaptive self-regulation and decreased NSSI risk in BPD.

Facial emotion recognition in borderline personality disorder

BACKGROUND

Emotion dysregulation represents a core symptom of borderline personality disorder (BPD). Deficits in emotion perception are thought to underlie this clinical feature, although studies examining emotion recognition abilities in BPD have yielded inconsistent findings. Method The results of 10 studies contrasting facial emotion recognition in patients with BPD (n = 266) and non-psychiatric controls (n = 255) were quantitatively synthesized using meta-analytic techniques.

RESULTS

Patients with BPD were less accurate than controls in recognizing facial displays of anger and disgust, although their most pronounced deficit was in correctly identifying neutral (no emotion) facial expressions. These results could not be accounted for by speed/accuracy in the test-taking approach of BPD patients.

CONCLUSIONS

Patients with BPD have difficulties recognizing specific negative emotions in faces and may misattribute emotions to faces depicting neutral expressions. The contribution of state-related emotion perception biases to these findings requires further clarification.

Show me how you walk and I tell you how you feel - a functional near-infrared spectroscopy study on emotion perception based on human gait

The ability to recognize and adequately interpret emotional states in others plays a fundamental role in regulating social interaction. Body language presents an essential element of nonverbal communication which is often perceived prior to mimic expression. However, the neural networks that underlie the processing of emotionally expressive body movement and body posture are poorly understood. 33 healthy subjects have been investigated using the optically based imaging method functional near-infrared spectroscopy (fNIRS) during the performance of a newly developed emotion discrimination paradigm consisting of faceless avatars expressing fearful, angry, sad, happy or neutral gait patterns. Participants were instructed to judge (a) the presented emotional state (emotion task) and (b) the observed walking speed of the respective avatar (speed task). We measured increases in cortical oxygenated haemoglobin (O2HB) in response to visual stimulation during emotion discrimination. These O2HB concentration changes were enhanced for negative emotions in contrast to neutral gait sequences in right occipito-temporal and left temporal and temporo-parietal brain regions. Moreover, fearful and angry bodies elicited higher activation increases during the emotion task compared to the speed task. Haemodynamic responses were correlated with a number of behavioural measures, whereby a positive relationship between emotion regulation strategy preference and O2HB concentration increases after sad walks was mediated by the ability to accurately categorize sad walks. Our results support the idea of a distributed brain network involved in the recognition of bodily emotion expression that comprises visual association areas as well as body/movement perception specific cortical regions that are also sensitive to emotion. This network is activated less when the emotion is not intentionally processed (i.e. during the speed task). Furthermore, activity of this perceptive network is, mediated by the ability to correctly recognize emotions, indirectly connected to active emotion regulation processes. We conclude that a full understanding of emotion perception and its neural substrate requires the investigation of dynamic representations and means of expression other than the face.

Difficulties with emotion regulation mediate the relationship between borderline personality disorder symptom severity and interpersonal problems

Problems with interpersonal functioning and difficulties with emotion regulation are core characteristics of borderline personality disorder (BPD). Little is known, however, about the interrelationship between these areas of dysfunction in accounting for BPD symptom severity. The present study examines a model of the relationship between difficulties with emotion regulation and interpersonal dysfunction in a community sample of adults (n = 124) with the full range of BPD symptoms. Results showed that difficulties with emotion regulation fully mediated the relationship between BPD symptom severity and interpersonal dysfunction. An alternative model indicated that interpersonal problems partially mediated the relationship between difficulties with emotion regulation and BPD symptom severity. These findings support existing theories of BPD, which propose that difficulties with emotion regulation may account for the types of interpersonal problems experienced by individuals with BPD and suggest further examination of the possibility that interpersonal dysfunction may worsen these individuals' difficulties with emotion regulation.

Emotional regulation and bodily sensation: interoceptive awareness is intact in borderline personality disorder

Emotional dysregulation is a core component of borderline personality disorder (BPD). Theoretical models suggest that deficits in labeling physiological sensations of emotion contribute to affective instability in BPD. Interoceptive awareness refers to the ability to perceive changes in internal bodily states, and is linked to the subjective experience and control of emotions. The authors tested whether differences in interoceptive awareness accounted for emotional instability in BPD. Patients diagnosed with BPD (n = 24) were compared to healthy controls (n = 30) on two established measures of interoceptive awareness, a heartbeat perception task and a heartbeat monitoring task. Contrary to their hypothesis, the authors observed no significant differences in objective measures of interoceptive awareness. Their findings provide strong evidence against the notion that difficulties in emotional regulation in BPD are connected to differences in interoceptive awareness.

Borderline personality features and emotional reactivity: the mediating role of interpersonal vulnerabilities

BACKGROUND AND OBJECTIVES

The purpose of this study was to examine the mediating role of interpersonal vulnerabilities in the association of borderline personality (BP) features with emotional reactivity to an interpersonal stressor.

METHODS

For this study, female university students with high (N = 23), mid (N = 23), and low (N = 22) BP features completed the Inventory of Interpersonal Problems-Personality Disorders-25 (IIP-PD-25). Self-reported emotions, skin conductance responses (SCRs), interbeat intervals, and heart rate variability measured emotional reactivity to a social rejection stressor.

RESULTS

BP features were positively associated with interpersonal dysfunction and predicted greater SCR reactivity and self-reported emotional reactivity. Interpersonal dysfunction mediated the association between BP features and physiological (SCRs), but not self-reported, emotional reactivity. In particular, scores on the interpersonal ambivalence subscale of the IIP-PD-25 mediated the association of BP features with SCR reactivity.

LIMITATIONS

This study examined BP features in a non-clinical sample, and relied on a relatively small sample. Furthermore, the design of the present study does not capture the potential transaction between interpersonal vulnerabilities and emotional dysfunction.

CONCLUSIONS

The findings of this study illuminate one potential mechanism underlying the heightened reactivity of persons with BP features to rejection, suggesting that interpersonal ambivalence plays a particularly important role in physiological reactivity.

Facial trust appraisal negatively biased in borderline personality disorder

Borderline personality disorder (BPD) is characterized by unstable interpersonal relationships and intense concerns regarding abandonment and rejection. Previous studies suggest that these and other symptoms of BPD may have their origin in a greater appraisal of untrustworthiness in others. However, it is not known whether this is a result of a heightened sensitivity to trust related stimuli, an improved ability to discriminate between such stimuli, or a response bias. Furthermore, impairment in facial fear appraisal may influence trust appraisal. Healthy controls and individuals diagnosed with BPD appraised human faces that were parametrically varied along either a trust or fear dimension. The BPD group exhibited a response bias to rate the untrustworthiness of facial stimuli higher compared to controls, but there were no significant differences in the discriminability or sensitivity of trustworthiness between groups. Furthermore, ambiguous trust decisions were associated with longer response times (RTs) in individuals with BPD relative to controls. Individuals with BPD have a facial appraisal bias specific to untrustworthiness that does not co-occur with impairments in the appraisal of fear.

The borderline empathy paradox: evidence and conceptual models for empathic enhancements in borderline personality disorder

Empirical evidence and therapeutic interactions have suggested that individuals with borderline personality disorder (BPD) may demonstrate enhancements in aspects of social-emotional cognition. To assess the empirical evidence for this phenomenon, and to comprehensively evaluate alternative hypotheses for its possible role in BPD etiology and symptoms, the authors systematically searched the literature for investigations of empathy in BPD and reviewed 28 studies assessing a range of empathic abilities. Considered together, these data demonstrated comparable levels of evidence for enhanced, preserved, and reduced empathic skills in individuals with BPD. Evidence for empathic enhancements is thus substantial but inconsistent across studies, being found mainly under more socially interactive experimental paradigms. Based on the results of the review and previous explanations for BPD symptoms, the authors propose a new model for explaining the borderline paradox: that a combination of increased attention to social stimuli and dysfunctional social information processing may account in part for the specific empathic enhancements and reduced overall social functioning in BPD.

Cerebrospinal fluid 5-hydroxyindolacetic acid correlates directly with negative affective intensity, but not affective lability, in human subjects

Centrally acting monoamines have long been thought to be associated with component traits of behavior and emotion and are potential biological mediators of psychopathology. In this study we tested the hypothesis that centrally acting monoamines would be associated with measures of affective instability (i.e. affective intensity and affective lability) in healthy and personality disordered human subjects. In total, 57 adult subjects including 19 psychiatrically healthy volunteers and 38 personality disordered individuals were assessed for affective instability with the affective intensity measure (AIM) and the Affective Lability Scale (ALS). Samples of cerebrospinal fluid (CSF) were collected for assay of 5-hydroxyindoleacitic acid (5-HIAA), homovanillic acid (HVA) and 3-methoxy-4-hydroxy-phenylglycol (MHPG). CSF 5-HIAA concentration correlated directly with overall AIM score and, specifically, with the AIM Negative Intensity score, in all subjects and in personality disordered subjects. This result was not affected but the addition of aggression scores or life history of mood disorder to the model. Neither CSF HVA nor MHPG were found to uniquely correlate with either AIM or ALS measure. Higher Affective Intensity scores, Negative Intensity scores, specifically, are directly correlated with higher basal levels of CSF 5-HIAA. This relationship was independent of aggression, life history of mood disorder and general personality traits.

Reduced sensitivity to emotional facial expressions in borderline personality disorder: effects of emotional valence and intensity

A heightened sensitivity towards negative emotional stimuli has been described for Borderline Personality Disorder (BPD). We investigated whether a faster and more accurate detection of negatively valent information in BPD can be confirmed by means of a visual search task which required subjects to detect a face with an incongruent emotional expression within a crowd of neutral faces. Twenty eight BPD patients and 28 nonpatients were asked to indicate whether a set of schematic neutral faces (3 × 3, 4 × 4 matrices) contained a happy or an angry face. Besides valence, the intensity of the target's emotion was varied in two steps. BPD patients and nonpatients both demonstrated an anger-superiority effect. However, no higher sensitivity towards negative stimuli was observed in BPD compared to nonpatients. BPD patients seem to rely to a stronger extent on controlled, i.e., serial, attention demanding processes when searching more subtle social-emotional information with positive valence.

Altered state and trait disgust in borderline personality disorder

Clinical experience suggests that the emotion disgust plays an important role in borderline personality disorder (BPD). We investigated 30 female patients with BPD and 30 healthy women who answered different measures of trait disgust, specifically disgust proneness, disgust sensitivity, and self-disgust. Moreover, all participants rated affective facial expressions as well as affective scenes according to perceived or elicited basic emotions. The patients with BPD reported elevated trait disgust, especially for the area of self-disgust. They also rated facial expressions of disgust as more intense than did the healthy women but only when the person who displayed this emotion was male. This sex-specific disgust bias was independent of depression and experienced sexual/physical abuse in the clinical group. Altogether, the patients with BPD showed a broad spectrum of altered disgust processes, which was positively correlated with disorder severity. Consequently, the assessment of disgust reactivity should be introduced as a diagnostic tool for this disorder.

Borderline personality disorder and emotional intelligence

The present study investigated emotional intelligence (EI) in borderline personality disorder (BPD). It was hypothesized that patients with BPD (n = 61) compared with patients with other personality disorders (PDs; n = 69) and nonpatients (n = 248) would show higher scores on the ability to perceive emotions and impairments in the ability to regulate emotions. EI was assessed with the Mayer-Salovey-Caruso Emotional Intelligence Test (Mayer, Salovey, and Caruso [New York: MHS, 2002]). As compared with the PD group and the nonpatient group, the patients with BPD displayed the anticipated deficits in their ability to understand, whereas no differences emerged with respect to their ability to perceive, use, and regulate emotions. In addition, a negative relationship was found between the severity of BPD and total EI score. However, this relationship disappeared when intelligence quotient was partialled out. These results suggest that BPD is associated with emotion understanding deficits, whereas temporary severity of BPD is associated with emotion regulation deficits.

Enhanced detection of emotional facial expressions in borderline personality disorder

BACKGROUND

Borderline personality disorder (BPD) is commonly proposed to be characterized by an enhanced sensitivity for emotional stimuli. In the present study, we investigated whether BPD patients show a superior detection of emotional facial expressions relative to healthy controls. The detection of emotional information in the environment represents an important facet of emotional sensitivity.

SAMPLING AND METHODS

Twenty patients with BPD were compared with 25 healthy controls. The participants were presented a rapid, continuous stream of neutral and randomly inserted emotional facial expressions and were asked to report the presentation of an emotional facial stimulus after each trial. Availability of cognitive resources was manipulated via two different task demands.

RESULTS

The participants with BPD performed significantly better in the detection of positive and negative facial expressions compared to the healthy controls. False alarm rates did not differ significantly between the two groups.

CONCLUSIONS

The BPD participants showed an enhanced detection of emotional expressions that might be related to the emotional disturbances they experience. In particular, we will discuss the role of this superior emotion detection (in combination with previously reported deficits in the labeling of emotional states) for the understanding of emotional instability in BPD.

Components of emotion dysregulation in borderline personality disorder: a review

Following Linehan's biosocial model, we conceptualize emotion dysregulation in borderline personality disorder (BPD) as consisting of four components: emotion sensitivity, heightened and labile negative affect, a deficit of appropriate regulation strategies, and a surplus of maladaptive regulation strategies. We review the evidence supporting each of these components. Given the complexity of the construct of emotion dysregulation and its involvement in many disorders, there is a need for research that specifies which components of emotion dysregulation are under study and also examines the interplay amongst these emotion dysregulation components.

Decreased sensitivity to facial emotions in adolescents with Borderline Personality Disorder

Whereas severe relationship dysfunction in BPD is well described in adolescence, little is known about the way these patients process facial expressions of emotion. Because few data are available regarding this issue, the present study compared the sensitivity to morphed facial emotional expressions of 22 BPD female adolescents versus 22 matched controls. Participants had to identify as rapidly as possible the various emotions displayed progressively and continuously on faces. Results indicate that adolescents with BPD are less sensitive to facial expressions of anger and happiness, i.e. they require more intense facial expressions than control participants to correctly identify these two emotions. However, they did not exhibit any deficit in recognizing fully expressed emotions. These results suggest that sensitivity to facial emotions is impaired in adolescents with BPD. Theoretical and clinical implications are discussed.

Physiological and self-assessed emotional responses to emotion-eliciting films in borderline personality disorder

According to Linehan's biosocial model, the core characteristic of borderline personality disorder (BPD) is emotional dysregulation. In the present study, we investigated two components of this model: baseline emotional intensity and emotional reactivity. A total of 60 women, 30 with BPD diagnosis and 30 age and sex-matched healthy subjects (HCs), participated in two experiments. In the first experiment, we evaluated emotional responses to six films designed to elicit discrete emotions (anger, fear, sadness, disgust, amusement and neutral). The second experiment evaluated emotional reactions to three emotion-eliciting films containing BPD-specific content (sexual abuse, emotional dependence and abandonment/separation). Skin conductance level, heart rate, and subjective emotional response were recorded for each film. Although self-reported data indicated that negative emotions at baseline were stronger in the BPD group, physiological measures showed no differences between the groups. Physiological results should be interpreted with caution since most BPD participants were under pharmacological treatment. BPD subjects presented no subjective heightened reactivity to most of the discrete emotion-eliciting films. Subjective responses to amusement and "BPD-specific content" films revealed significant between-group differences. These findings suggest that the main characteristic of BPD might be negative emotional intensity rather than heightened emotional reactivity.

Toward a definition of affective instability

Affective instability is a psychophysiological symptom observed in some psychopathologies. It is a complex construct that encompasses (1) primary emotions, or affects, and secondary emotions, with each category having its own characteristics, amplitude, and duration, (2) rapid shifting from neutral or valenced affect to intense affect, and (3) dysfunctional modulation of emotions. Affective instability is often confused with mood lability, as in bipolar disorders, as well as with other terms. To clarify the concept, we searched databases for the term affective instability and read related articles on the topic. In this article we situate the term within the current affective nomenclature and human emotional experience, explore its psychophysiological features, and place it within the context of psychopathology. We explain why the term can potentially be confused with mood pathology and then define affective instability as an inherited temperamental trait modulated by developmental experience.

Mental state decoding abilities in young adults with borderline personality disorder traits

Previous studies have demonstrated that patients with borderline personality disorder (BPD) tend to misattribute malevolence to benign social stimuli, including facial expressions. Yet, facial emotion recognition studies examining those with BPD have yielded mixed results, with some studies showing impaired accuracy and others demonstrating enhanced accuracy in the recognition of emotions or mental states. The current study examined the ability to decode mental states from photographs of just the eye region of faces in a nonclinical sample of young adults who exhibited BPD traits (high BPD) compared with those who did not (low BPD). Group differences in mental state decoding ability depended on the valence of the stimuli. The high-BPD group performed better for negative stimuli compared with the low-BPD group, but did not perform significantly different from the low-BPD group for stimuli of neutral or positive valence. The high-BPD group also demonstrated a response bias for attributing negative mental states to facial stimuli. In addition, findings suggested that the group difference in accuracy for negative stimuli could not be explained by response bias, because the group difference in response bias for negative stimuli did not reach significance. These findings suggest that BPD traits may be associated with enhanced ability to detect negative emotions and a bias for attributing negative emotions to nonnegative social stimuli.

Attentional processes and responding to affective faces in youth with borderline personality features

This study examined attentional biases for emotional faces in borderline personality disorder (BPD). Twenty-one outpatient youth (aged 15-24 years) meeting three or more DSM-IV BPD criteria and 20 community-derived participants (aged 15-24 years) with no history of psychiatric problems and not meeting any BPD criteria completed a modified dot-probe task that tested automatic (30 ms) and controlled (500 ms) stages of information processing. The findings indicate that, compared with healthy controls, youth with borderline features were faster to respond to congruent rather than incongruent fear stimuli. This effect was independent of state anxiety and was observed during the 30 ms presentation of fearful faces. There was no significant effect for happy or angry faces. Youth with borderline features were also slower to respond to incongruent rather than paired neutral trials, indicating difficulties in disengaging attention from the perceived threat. Such differences were not found for the healthy controls. Thus, youth with borderline features had an attentional bias for fearful faces that reflected difficulty in disengaging attention from threatening information during pre-conscious stages of attention. This finding extends previous research highlighting the diminished capacity for affect regulation and subsequent engagement in behavioural strategies to avoid distress in BPD. Future research should explore the relationship between information processing, emotion regulation in adult BPD samples.

Social cognition in borderline personality disorder: evidence for dichotomous thinking but no evidence for less complex attributions

This experiment investigated social cognition in borderline personality disorder (BPD). We tested whether BPD-patients' evaluations of others were characterized by splitting, dichotomous thinking, or negativity; and whether they showed less complex understanding of others. Participants discussed a problem with three alleged mental health worker trainees, performing three interpersonal roles (rejecting, accepting and neutral). Participants evaluated trainees in a structured response format and in a semi-structured interview. BPD-patients (n = 18) were compared to Cluster-C personality disorder patients (n = 18) and nonpatients (n = 18). From visual analog scales with opposite trait descriptions (structured response format) negativity, dichotomous thinking, and splitting scores were derived. The interviews were scored by an independent rater on affect tone, differentiation, and complexity of attributions. BPD-patients showed, in all conditions, and in both response formats, more dichotomous thinking than control groups. Evidence for splitting as specific BPD-characteristic was not convincing, and more negativity in BPD was only found with the rejecting role and structured responses. The interview-based evaluations by BPD-patients could not be discriminated from nonpatients in cognitive complexity. Results indicate that dichotomous thinking, and not so much splitting, negativity, or less complexity, is central in the interpretation of others by BPD-patients. Treatment might address dichotomous thinking to reduce BPD-patients' interpersonal problems.

Hypersensitivity in borderline personality disorder during mindreading

BACKGROUND

One of the core symptoms of borderline personality disorder (BPD) is the instability in interpersonal relationships. This might be related to existent differences in mindreading between BPD patients and healthy individuals.

METHODS

We examined the behavioural and neurophysiological (fMRI) responses of BPD patients and healthy controls (HC) during performance of the 'Reading the Mind in the Eyes' test (RMET).

RESULTS

Mental state discrimination was significantly better and faster for affective eye gazes in BPD patients than in HC. At the neurophysiological level, this was manifested in a stronger activation of the amygdala and greater activity of the medial frontal gyrus, the left temporal pole and the middle temporal gyrus during affective eye gazes. In contrast, HC subjects showed a greater activation in the insula and the superior temporal gyri.

CONCLUSION

These findings indicate that BPD patients are highly vigilant to social stimuli, maybe because they resonate intuitively with mental states of others.

Affect intensity and negative mood regulation (NMR) expectancies: a preliminary Indian study

Individuals differ in the intensity with which they typically experience affect as well as in their beliefs regarding their ability to alleviate negative mood states. These variables have been implicated in a range of clinical problems. Most studies utilize a single index of affect intensity. The differential correlates of positive and negative affect intensity, their association with negative mood regulation expectancy and their role as predictors of psychological outcomes have been insufficiently explored. This study aimed at exploring the relationship of affect intensity variables with negative mood regulation (NMR) expectancy, their association with age and gender and examining the role of affect intensity and NMR expectancy as predictors of stress and well being in a community sample of Indian adults. The sample consisted of 206 participants aged between 20 and 60 years. Higher age was associated with higher NMR expectancy but lower positive affect intensity. Positive and negative affect intensity showed differential patterns of association with NMR expectancy. Higher negative affect intensity was associated with lower NMR expectancy whereas higher positive affect intensity was associated with higher NMR expectancy. Affect intensity and NMR expectancy variables jointly predicted 30-39% of variance in perceived stress and well being. Implications for further research are discussed.

Normal mind-reading capacity but higher response confidence in borderline personality disorder patients

AIM

Borderline personality disorder (BPD) is characterized by a pattern of instability in interpersonal relationships. Therefore, the investigation of social cognition is of compelling interest for the understanding of BPD. One important aspect of social cognition is theory of mind (ToM), which describes the ability to understand others' mental states, such as beliefs, desires and intentions. The aim of the present study was to further investigate ToM in BPD patients.

METHODS

The Reading the Mind in the Eyes Test was assessed in 31 BPD patients and 27 healthy controls. In addition, the test was complemented by a response confidence rating.

RESULTS

BPD patients and healthy controls did not differ in their mind-reading ability with respect to accuracy, but patients were significantly more often highly confident in their decisions than controls.

CONCLUSIONS

Overconfidence might contribute to the severe difficulties in interpersonal relationships often observed in BPD patients.

Emotion regulation deficits in eating disorders: a marker of eating pathology or general psychopathology?

Preliminary evidence indicates that individuals with eating disorders (ED) show emotion regulation (ER) difficulties. However, it is yet unclear whether different types of ED differ in their ER profile and whether certain ER difficulties are specific for ED or rather a transdiagnostic factor. Twenty women with anorexia nervosa (AN), 18 with bulimia nervosa (BN), 25 with binge eating disorder (BED), 15 with borderline personality disorder (BPD), 16 with major depressive disorder (MDD) and 42 female healthy controls (HC) were administered the Emotion Regulation Questionnaire, the Inventory of Cognitive Affect Regulation Strategies, the Difficulties in Emotion Regulation Scale and the Affect Intensity Measure. The ED groups reported significantly higher levels of emotion intensity, lower acceptance of emotions, less emotional awareness and clarity, more self-reported ER problems as well as decreased use of functional and increased use of dysfunctional emotion regulation strategies when compared to HC. No significant differences between the ED groups emerged for most ER variables. However, there were indications that the BED group may show a slightly more adaptive pattern of ER than the two other ED groups. As a whole, all clinical groups performed very similar on most ER variables and reported more difficulties regulating their emotions than HC. The findings suggest that ER difficulties are not linked to a particular diagnostic category. Instead, ER difficulties appear to be a transdiagnostic risk and/or maintenance factor rather than being disorder-specific.

Facial emotion triggered cerebral potentials in treatment-resistant depression and borderline personality disorder patients of both genders

BACKGROUND

Processing facial expressions of emotion is deteriorated in depression, which might be more pronounced in treatment-resistant depression (TRD), especially when the latter is comorbid with borderline personality disorder (BPD). Neurophysiologically, both early perceptual and late cognitive cerebral processes of facial emotions can be illustrated by event-related potentials (ERPs).

METHODS

We therefore tried the ERPs to facial expressions of Neutral, Anger, Happiness, and Sadness in 25 patients with TRD, 15 with BPD, 22 with their comorbidity (TRD+BPD), as well as in 37 healthy volunteers. The depression levels of participants were measured with the Plutchik-van Praag Depressive Inventory (PVP).

RESULTS

There was no group difference regarding either N1 (N170), P2, N2, P3a or P3b latency or amplitude to the four facial emotions. Reaction times (RTs) to Anger (p<.01), Happiness (p<.01), and Sadness (p<.001) in TRD, and those to Anger (p<.01) and Happiness (p<.01) in TRD+BPD patients were longer than those in the healthy volunteers. RTs to the four facial expressions were positively correlated (p<.01) with their depressive moods in all participants. In addition, PVP was positively correlated with the P2 latency to Anger in TRD+BPD patients (Fz, p<.01; Cz, p<.01; Pz, p<.01).

CONCLUSIONS

BPD contributed little to TRD or TRD+BPD regarding cerebral processing of facial emotions, however, other cognitive and behavioral data suggest a generalized impairment when responding to facial emotions in TRD and TRD+BPD patients, and a deteriorated perceptual processing of Anger in TRD+BPD patients.
