Borderline personality disorder and emotional responding: A review of the research literature

Beyond clinical observations: a scoping review of AI-detectable observable cues in borderline personality disorder

Borderline Personality Disorder (BPD), impacting approximately 2% of adults worldwide, presents a formidable challenge in psychiatric diagnostics. Often underdiagnosed or misdiagnosed, BPD is associated with high morbidity and mortality. This scoping review embarks on a comprehensive exploration of observable cues in BPD, encompassing language patterns, speech nuances, facial expressions, nonverbal communication, and physiological measurements. The findings unveil distinctive features within the BPD population, including language patterns emphasizing external viewpoints and future tense, specific linguistic characteristics, and unique nonverbal behaviors. Physiological measurements contribute to this exploration, shedding light on emotional responses and physiological arousal in individuals with BPD. These cues offer the potential to enhance diagnostic accuracy and complement existing diagnostic methods, enabling early identification and management in response to the urgent need for precise psychiatric care in the digital era. By serving as possible digital biomarkers, they could provide objective, accessible, and stress-reducing assessments, representing a significant leap towards improved psychiatric assessments and an invaluable contribution to the field of precision psychiatry.

Validating the biosocial model of borderline personality disorder: Findings from a longitudinal study

This longitudinal study aimed to validate the biosocial theory of borderline personality disorder (BPD) by examining the transactional relationship between individual vulnerabilities and parental invalidation, and their links to BPD symptoms. We recruited a sample of 332 adolescents (mean age = 14.18 years; 58.3% female) residing in Singapore and administered self-report measures across three time-points (six months apart). Results from our path analytic model indicated that parental invalidation, impulsivity, and emotional vulnerability exhibited unique predictive associations with emotion dysregulation six months later. There was also a reciprocal prospective relationship between emotion regulation difficulties and BPD symptoms. Using random-intercepts cross-lagged panel models, we found partial evidence for a within-individual reciprocal relationship between parental invalidation and emotional vulnerability, and a unidirectional relationship of within-individual changes in impulsivity positively predicting changes in parental invalidation six months later. Overall, the study provided partial empirical support for the biosocial model in a Singaporean context.

Neurophysiological insights into impaired mentalization in borderline personality disorder an electroencephalography study

INTRODUCTION

Borderline personality disorder (BPD) is characterized by interpersonal and emotional instabilities, recurring suicidal tendencies, and feelings of emptiness. Childhood adverse event is reported in 70%-80% of cases involving BPD. Furthermore, the deficiency in mentalization capacity plays a significant role in emotion dysregulation and social interaction problems within individuals with BPD. This study explored the relationship among childhood adverse experiences, mentalization capacity, and neurophysiological activity in patients with BPD.

METHODS

Resting-state electroencephalography was used to identify the neural correlates associated with childhood adversity and mentalization deficits. The participants included 45 patients with BPD and 15 healthy controls.

RESULTS

The BPD group exhibited reduced alpha activity during eyes-closed rest, indicating heightened arousal even during relaxation. Correlations were found between the power spectral density (PSD) and mentalization capacity in the delta and theta ranges, suggesting an association between PSD and emotional awareness and expression. Gamma activity negatively correlated with psychic equivalence, implying a blurring of the boundaries between internal mental experiences and the external world.

CONCLUSION

These findings offer insights into the pathophysiology of BPD, provide potential diagnostic markers, and suggest personalized treatment approaches based on mentalization traits.

Altered psychobiological reactivity but no impairment of emotion recognition following stress in adolescents with non-suicidal self-injury

Impairments in both stress regulation and emotion recognition have been associated with borderline personality disorder (BPD) and non-suicidal self-injury (NSSI). Although it has been proposed that emotion recognition deficits particularly emerge during stress, this hypothesis has not been fully investigated. Adolescents with and without NSSI performed emotion recognition tasks before and after the employment of the Trier Social Stress Test (TSST). The psychobiological stress response was captured with psychological self-reports (affect, stress and dissociation), physiological recordings (heart rate, HR, and heart rate variability, HRV) and endocrinological sampling of saliva (cortisol and alpha-amylase). Mixed-linear models were applied to analyze stress-induced changes in emotion recognition performance and respective stress response measures. The TSST elicited altered psychobiological stress responses in adolescents with NSSI: A more pronounced decrease in positive affect, a more pronounced increase in negative affect, a less pronounced increase in HR, a less pronounced decrease in HRV and a more pronounced increase in alpha-amylase throughout the stress induction than adolescents without NSSI. Stress responses (dissociation, negative affect, cortisol and HR) differed as a function of BPD severity on a continuum, illustrating greater reactivity on self-reports but decreased biological responsiveness in those with greater BPD severity. Stress induction had similar effects on emotion recognition in adolescents with and without NSSI. Recognition sensitivity and recognition speed equally increased, in the absence of any differences in recognition accuracy. In contrast to prominent propositions, psychosocial stress does not appear to account for impaired emotion recognition across the BPD spectrum.

Is borderline personality disorder really an emotion dysregulation disorder and, if so, how? A comprehensive experimental paradigm

BACKGROUND

Leading theories suggest that borderline personality disorder (BPD) is an emotion dysregulation disorder involving lower basal vagal tone, higher baseline emotion, heightened emotional reactivity, delayed emotional recovery, and emotion regulation deficits. However, the literature to date lacks a unifying paradigm that tests all of the main emotion dysregulation components and comprehensively examines whether BPD is an emotion dysregulation disorder and, if so, in what ways. This study addresses the empirical gaps with a unified paradigm that assessed whether BPD is characterized by five leading emotion dysregulation components compared to generalized anxiety disorder (GAD) and healthy control (HC) groups.

METHODS

Emotion was assessed across self-report, sympathetic, and parasympathetic indices. Participants with BPD, GAD, and HCs (N = 120) first underwent baseline periods assessing basal vagal tone and baseline emotional intensity, followed by rejection-themed stressors assessing emotional reactivity. Participants then either reacted normally to assess emotional recovery or attempted to decrease emotion using mindfulness or distraction to assess emotion regulation implementation deficits.

RESULTS

Individuals with BPD and GAD exhibited higher self-reported and sympathetic baseline emotion compared to HCs. The BPD group also exhibited self-reported emotion regulation deficits using distraction only compared to the GAD group.

CONCLUSIONS

There is minimal support for several emotion dysregulation components in BPD, and some components that are present appear to be pervasive across high emotion dysregulation groups rather than specific to BPD. However, BPD may be characterized by problems disengaging from emotion using distraction.

The mediational role of emotion regulation in the relationship between personality and subjective well-being

In this research we examined relationships between Big Five personality traits, emotion regulation strategies and subjective well-being. In two studies we explored the mediational role of habitual use of two regulation strategies: reappraisal and suppression in the relationship between personality traits and two aspects of well-being (i.e., life satisfaction and experience of positive affect and negative affect). In Study 1 (n = 233) we found that the most robust predictors of higher life satisfaction were higher extraversion, conscientiousness, emotional stability (lower neuroticism) and reappraisal, as well as lower suppression of emotions. We obtained similar pattern of results in Study 2 (n = 265) which showed that higher positive affect was significantly predicted by higher extraversion, conscientiousness, emotional stability, and reappraisal. Negative affect was negatively predicted only by emotional stability. Additional analyses indicated that suppression mediated the link between extraversion and life satisfaction, whereas reappraisal mediated associations of emotional stability with life satisfaction and positive affect. The studies reveal the role of emotion regulation for extraversion and emotional stability and their association with well-being.

A mixed methods examination of emotional expression and its impact on emotion regulation effectiveness in borderline personality disorder

BACKGROUND AND OBJECTIVES

Emotional expression (i.e., identifying and labeling emotion using specific words), is theorized to reduce negative emotion and facilitate emotion regulation. However, it remains unclear how individuals with borderline personality disorder express emotion, and whether this influences their emotion regulation. This study examined whether: 1) emotional expression in borderline personality disorder differed from healthy controls based on word valence, emotionality, and vocabulary; and 2) whether such characteristics predict emotion regulation effectiveness across self-reported and physiological emotion domains differentially across these groups.

METHODS

Individuals with borderline personality disorder (n = 29) and age and sex-matched healthy controls (n = 30) listened to an evocative story, expressed emotion, and regulated emotion by applying Mindfulness or Cognitive Reappraisal. Emotion regulation was measured by changes in self-report, parasympathetic, and sympathetic emotion, while implementing the emotion regulation strategies. The words used to express emotion were coded based on valence, emotionality, and depth of vocabulary.

RESULTS

Generalized estimating equations revealed no differences between groups in valence, emotionality, and vocabulary. Additionally, using a larger emotional vocabulary predicted more effective sympathetic emotion regulation, and using more negatively valenced words predicted more effective parasympathetic emotion regulation across groups.

LIMITATIONS

Among other things, this study is limited by its predominantly female sample, and that it does not determine whether valence, emotionality, or vocabulary independently predict emotional expression effectiveness.

CONCLUSIONS

Emotional expression may not be deficient in borderline personality disorder across the indices studied. Using more negative words and broadening vocabulary while expressing emotion may offer emotion regulation benefits.

A Day in the Life of Borderline Personality Disorder: A Preliminary Analysis of Within-Day Emotion Generation and Regulation

In Linehan's (1993) biosocial theory, borderline personality disorder (BPD) results in part from frequent, intense, negative emotions and maladaptive behavioral responses to those emotions. We conducted a secondary data analysis of an intensive single-case experimental design to explore hourly relations among behavioral responses and emotions in BPD. Eight participants with BPD (M _age = 21.57, 63% female; 63% Asian) reported their emotions and behaviors hourly on two days. Participants reported a neutral-to-negative average emotional state with substantial variability each day. This emotional state was characterized most frequently by anxiety and joy. Participants tended to "dig into", or savor, experiences of joy, but problem-solve around, push away, or accept anxiety. Acceptance predicted hour-by-hour increases in negative emotion intensity, and pushing emotions away predicted hour-by-hour increases in positive emotion intensity. These results suggest that anxiety dominates the emotional experiences of people with BPD and co-occurs with a variety of emotion regulation strategies, while joy co-occurs with strategies designed to prolong emotional experiences. Despite its general adaptiveness, acceptance may be less effective, and pushing emotions away may be more effective, than other emotion regulation strategies at improving momentary negative emotions for those with BPD. We discuss the preliminary nature of these findings and encourage future researchers to build on them in larger samples with more severe presentations of BPD.

Emotion regulation and borderline personality features in daily life: The role of social context

BACKGROUND

Borderline personality disorder (BPD) is associated with emotional dysfunction and interpersonal sensitivity. Yet, little work has characterized how BPD features predicts emotional reactivity and emotion regulation behaviors in response to interpersonal stress relative to other forms of stress.

METHODS

Participants were 152 university students who completed baseline measures of BPD features and complied with two-week daily diary procedures assessing daily emotion regulation strategy use in response to social and non-social stressors.

RESULTS

Generalized estimating equations revealed that BPD features predicted greater negative and positive emotions in response to daily stressors, and interacted with type of stressor in predicting urges and behaviors. Elevated BPD features was associated with greater urges for dysfunctional emotion regulatory behaviors and fewer functional emotion regulatory behaviors to a greater extent in response to social (versus non-social) stressors.

LIMITATIONS

This study was limited by its focus on past-day retrospective recall. Further, the student sample limits the generalizability of these findings.

CONCLUSIONS

These findings suggest that individuals with elevated BPD features may have less functional emotion regulation in social contexts.

The mediating effect of difficulties in emotion regulation on the association between childhood maltreatment and borderline personality disorder

BACKGROUND

Childhood maltreatment and difficulties in emotion regulation are common in patients with Borderline Personality Disorder (BPD) and Depressive Disorders (DD).

OBJECTIVE

This study examines differences between patients with BPD and patients with DD, regarding childhood maltreatment and difficulties in emotion regulation as well as the mediating effect of different aspects of emotion regulation deficits on the association between childhood maltreatment and BPD-symptoms.

METHOD

A total of 305 participants, 177 with BPD and 128 with DD completed an assessment including the Childhood Trauma Questionnaire (CTQ), the Emotion Regulation Scale (DERS), the Brief Symptom Inventory (BSI), and the Structured Clinical Interview for DSM-IV (SCID). Data was analyzed using multiple analyses of variances and mediation analyses.

RESULTS

Patients with BPD reported more childhood maltreatment and more difficulties in emotion regulation than patients with DD. When general symptom severity, age, and gender were included in the analysis as covariates only group differences regarding 'impulse control difficulties' (F(1,299) = 38.97, p < .001, η_p² = .115), 'limited access to emotion regulation strategies' (F(1,299) = 4.66, p = .032, η_p² = .015), and 'lack of emotional clarity' (F(1,299) = 9.38, p = .002, η_p² = .030) remained statistically significant. A mediation analysis, including above-mentioned covariates, indicated an association between emotional abuse and BPD-symptoms, which was mediated by difficulties in emotion regulation (indirect effect B = .012, 95% CI [.001; .031], R² = .429). Subscale analyses revealed 'impulse control difficulties' as the aspect of difficulties in emotion regulation that has the greatest impact on this association (B = .021, 95% CI [.003; .045]).

CONCLUSIONS

Patients with BPD display more childhood maltreatment and difficulties in emotion regulation than patients with DD. Difficulties in emotion regulation, especially difficulties in impulse control, seem to play an important role in the association between childhood emotional abuse and BPD-symptoms.

Insomnia in Patients with Borderline Personality Disorder

OBJECTIVE

Both sleep disorders and BPD are prevalent in the population, and one is often a comorbidity of the other. This narrative review aims to assess contemporary literature and scientific databases to provide the current state of knowledge about sleep disorders in patients with borderline personality disorder (BPD) and clinical suggestions for managing sleep disorders in BPD patients and future research direction.

METHODS

Articles were acquired via PubMed and Web of Science, and papers published between January 1980 and October 2020 were extracted. Authors made a series of literature searches using the keywords: Sleep problems, Insomnia, Nightmares, Obstructive sleep apnea, Borderline personality disorder. The inclusion criteria were: published in peer-reviewed journals; studies in humans; or reviews on the related topic; English language. The exclusion criteria were: abstracts from conferences; commentaries; subjects younger than 18 years. After an inspection of the full texts, 42 papers from 101 were selected. Secondary documents from the reference lists of the primary designated papers were searched, assessed for suitability, and included. In total, 71 papers were included in the review process.

RESULTS

Sleep disturbance is common among patients with BPD. Nevertheless, the number of investigations is limited, and the prevalence differs between 5-45%. Studies assessing objective changes in sleep architecture in BPD show inconsistent results. Some of them identify REM sleep changes and a decrease in slow-wave sleep, while other studies found no objective sleep architecture changes. There is also a higher prevalence of nightmares in patients with BPD. Untreated insomnia can worsen BPD symptoms via interference with emotional regulation. BPD itself seems to influence the subjective quality of sleep significantly. Proper diagnosis and treatment of sleep disorders in patients with BPD could lead to better results in therapy. Psychotherapeutic approaches can improve both sleep disorders and BPD symptoms.

CONCLUSION

Recognising and managing sleep disorders in patients with BPD may help alleviate the disorder's symptoms. Treatment of people with BPD may be more effective if the treatment plan explicitly addresses sleep problems. Further research is needed to reach reliable conclusions.

Inhibitory control under emotional contexts in women with borderline personality disorder: An electrophysiological study

Borderline personality disorder (BPD) is characterized by emotional dysregulation and difficulties in cognitive control. Inhibitory control, meanwhile, is modulated by the presence of emotional stimuli. The objective of the present study was to examine the effects of implicit emotional contexts on response inhibition in BPD patients. Participants performed a response inhibition task (Go-NoGo) under 3 background context conditions: neutral, pleasant and unpleasant. Behavioral performance did not differed between groups. Significantly higher P3NoGo amplitudes, shorter N2 latencies and lower global connectivity were observed in the patients regardless of the emotional valence of the background images compared to controls. In addition, higher P3NoGo amplitudes were correlated with more pronounced psychopathological symptoms. Emotional contexts enhanced N2 amplitudes compared to neutral ones in both groups. Results indicate that BPD required greater neural effort to successfully perform the inhibitory task. Finally, BPD showed lower synchronization between cortical regions, which may indicate a disruption in the effective temporal coupling of distributed areas associated with emotional stimuli-processing during both response and response inhibition.

Self-Contempt, the Working Alliance and Outcome in Treatments for Borderline Personality Disorder: An Exploratory Study

Objective. We examined the role of expressed self-contempt in therapy for borderline personality disorder (BPD). Based on previous literature on BPD, we assumed an association between the self-contempt and the core symptoms of BPD. We also studied the progression of expressed self-contempt during the treatment and its effect on the alliance and the outcomes of treatment.Method. We rated the expressed self-contempt in 148 tape-recorded sessions with patients with BPD (N = 50), during a brief psychiatric treatment. We rated self-contempt at three time-points, using an observer-rate scale. Self-reported questionnaires were used to assess symptoms and the working alliance.Results. There are some associations between self-contempt and BPD symptoms. Expressed self-contempt did not change during the treatment. One measure of self-contempt was associated with a weaker alliance rated by the patients and with a stronger alliance rated by the therapists. The expression of high self-contempt was not predictive of outcomes when the initial level of problems was controlled for.Conclusions. The results highlight the importance to examine the complex effects of self-contempt in BPD undergoing treatment in a differentiated manner and suggest to clinicians and researchers to be attentive to this specific emotional state, and change therein, in psychotherapy.Keywords: Self-contempt; Borderline Personality Disorder; Brief Treatment; Therapeutic Alliance; EmotionTrial registration: ClinicalTrials.gov identifier: NCT01896024.

Der Einsatz von Verhaltensexperimenten bei Patienten mit Borderline-Persönlichkeitsstörung

Der vorliegende Artikel erarbeitet, wie Verhaltensexperimente bei Patienten mit Borderline-Persönlichkeitsstörung (BPS) genutzt werden können, um Grundannahmen zu überprüfen sowie neue Erfahrungen zu generieren, aufgrund derer alternative Kognitionen entwickelt werden können. Die BPS gilt als eine schwer zu behandelnde psychische Störung, die durch eine Instabilität von zwischenmenschlichen Beziehungen, Verhalten und Emo­tionen gekennzeichnet wird. Problemverhaltensweisen wie Selbstverletzungen oder Dissoziationen werden als Coping-Strategien eingesetzt, um die Dysregulationen zu kontrollieren. Verschiedene Störungsbereiche werden mitsamt typischer kognitiver Dysfunktionen vorgestellt sowie mögliche Ansatzpunkte für Verhaltensexperimente anhand von Fallbeispielen illustriert. Der Einsatz von Verhaltensexperimenten im Rahmen einer kognitiv-verhaltenstherapeutischer Psychotherapie für Patienten mit BPS kann sehr hilfreich sein. Allerdings werden nicht zwangsläufig neue Erfahrungen in die Grundannahmen eingearbeitet, in manchen Fällen halten Patienten an den dysfunktionalen Kognitionen fest.

A Meta-analysis and Systematic Review of Emotion-Regulation Strategies in Borderline Personality Disorder

Emotion dysregulation is often considered a core characteristic of individuals with borderline personality disorder (BPD). With the development and strength of a contemporary affective-science model that encompasses both healthy emotion regulation (ER) and emotion dysregulation, this model has increasingly been used to understand the affective experiences of people with BPD. In this meta-analysis and review, we systematically review six of the most commonly studied ER strategies and determine their relative endorsement in individuals with elevated symptoms of BPD compared to individuals with low symptoms of BPD and healthy controls, as well as to individuals with other mental disorders. Results from 93 unique studies and 213 different effect-size estimates indicated that symptoms of BPD were associated with less frequent use of ER strategies that would be considered more effective at reducing negative affect (i.e., cognitive reappraisal, problem solving, and acceptance) and more frequent use of ER strategies considered less effective at reducing negative affect (i.e., suppression, rumination, and avoidance). When compared to individuals with other mental disorders, people with BPD endorsed higher rates of rumination and avoidance, and lower rates of problem solving and acceptance. We also review important contributions from studies of ER in BPD that we were unable to incorporate into our meta-analysis. We conclude by discussing how the pattern of using ER strategies in BPD contributes to emotion dysregulation and also the potential reasons for this pattern, integrating both Gross's extended process model of ER and Linehan's updated theoretical account on the development of emotion dysregulation.

Is It Personal? Context Moderates BPD Effects on Spontaneous Rumination and Distress

Borderline personality disorder (BPD) is associated with the use of maladaptive emotion regulation (ER) that predicts unstable interpersonal relationships and emotion dysregulation. Rumination, a maladaptive cognitive ER response, may be one mechanism by which those with BPD experience emotion dysregulation. However, it remains unclear whether emotion dysregulation is linked to rumination in general, or to rumination during interpersonal situations that often prove challenging for those with BPD. The present study examined whether interpersonal exclusion conferred an increased risk to spontaneously ruminate among those with elevated BPD features relative to an impersonal negative mood induction, and whether spontaneous rumination mediated the effects of BPD features on distress reactivity. Overall, BPD features predicted stronger tendencies to spontaneously ruminate and higher levels of distress following interpersonal exclusion; spontaneous rumination following interpersonal exclusion mediated the effects of BPD features on distress. These findings highlight the importance of context when examining ER outcomes.

Emotional Reactivity in Borderline Personality Disorder: Theoretical Considerations Based on a Meta-Analytic Review of Laboratory Studies

Emotional hyperreactivity (Linehan, 1993) is the most investigated construct in borderline personality disorder (BPD). However, experimental studies revealed mixed results on the topic. Our main objective is to comprehensively summarize the results on emotional reactivity in BPD compared to healthy controls (HCs), using a meta-analytic approach, considering different emotional response systems (physiology, behavior, self-report). We included 31 experimental studies (1,675 subjects). We observed null to small effect sizes for several physiological and behavioral outcomes. Conversely, BPD subjects revealed a moderate to large difference in valence attributed to emotional stimuli and a small difference in self-reported arousal. Significant differences in pooled effect sizes were found between self-report and physiological outcomes. Several sources of heterogeneity were explored. In general, the hyperreactivity hypothesis was not supported. Additional dysfunctional processes should be taken into consideration to understand BPD emotional responsiveness.

Getting Specific about Emotion and Self-Inflicted Injury: An Examination Across Emotion Processes in Borderline Personality Disorder

This study aimed to examine which specific emotion processes influence self-inflicted injury: basal respiratory sinus arrhythmia, baseline negative emotional intensity, emotional reactivity, or emotion regulation deficits. Self-injuring individuals with borderline personality disorder (N = 22) reported their lifetime self-injury frequency. Basal respiratory sinus arrhythmia and baseline skin conductance responses measurements were collected. Participants then either reacted as they usually would (i.e., emotional reactivity), or utilized mindfulness- or distraction-based strategies (i.e., emotion regulation), in response to negative images while self-reported negative emotion and skin conductance were monitored. Higher basal respiratory sinus arrhythmia and baseline emotional intensity predicted higher lifetime self-injury frequency. Chronic, resting emotion processes may be more important targets for reducing self-injury compared to labile, acute emotion processes.

Heart rate variability during a cognitive reappraisal task in female patients with borderline personality disorder: the role of comorbid posttraumatic stress disorder and dissociation

BACKGROUND

Emotion dysregulation is a core feature of borderline personality disorder (BPD), which often co-occurs with posttraumatic stress disorder (PTSD). Difficulties in emotion regulation (ER) have been linked to lower high-frequency heart rate variability (HF-HRV), a measure of autonomous nervous system functioning. However, previous research on vagally-mediated heart rate in BPD revealed heterogeneous findings and the effects of comorbid PTSD and dissociation on HF-HRV are not yet completely understood. This study aim to investigate HF-HRV during resting-state and an ER task in female BPD patients with comorbid PTSD (BPD + PTSD), patients without this comorbidity (BPD), and healthy controls (HC).

METHODS

57 BPD patients (BPD: n = 37, BPD + PTSD: n = 20) and 27 HC performed an ER task with neutral, positive, and negative images. Participants were instructed to either attend these pictures or to down-regulate their upcoming emotions using cognitive reappraisal. Subjective arousal and wellbeing, self-reported dissociation, and electrocardiogram data were assessed.

RESULTS

Independent of ER instruction and picture valence, both patient groups (BPD and BPD + PTSD) reported higher subjective arousal and lower wellbeing; patients with BPD + PTSD further exhibited significantly lower HF-HRV compared with the other groups. Higher self-reported state dissociation predicted higher HF-HRV during down-regulating v. attending negative pictures in BPD + PTSD.

CONCLUSIONS

Findings suggest increased emotional reactivity to negative, positive, and neutral pictures, but do not provide evidence for deficits in instructed ER in BPD. Reduced HF-HRV appears to be particularly linked to comorbid PTSD, while dissociation may underlie attempts to increase ER and HF-HRV in BPD patients with this comorbidity.

Nonsuicidal Self-Injury and Suicidal Behaviors in Girls: The Case for Targeted Prevention in Preadolescence

Non-suicidal self-injury (NSSI) affects 15-20% of adolescents-disproportionately girls-and is a strong predictor of eventual suicide attempts and suicide. Many girls now initiate NSSI before age 10. These early-starters exhibit greater frequency of NSSI, use more diverse methods, and are hospitalized more often, yet there are no empirically supported prevention programs for preadolescents. Obstacles to prevention include ascertaining who is sufficiently vulnerable and specifying mechanistic intervention targets. Recent research indicates that (1) preadolescent girls with ADHD who are also maltreated are at alarming risk for NSSI and suicide attempts by adolescence, and (2) the conjoint effects of these vulnerabilities are sufficiently potent for targeted prevention. Research also indicates that existing interventions are effective in altering child- and family-level mechanisms of NSSI. These interventions alter neurobiological markers of vulnerability, which can be used as proximal efficacy signals of prevention response, without waiting for NSSI and suicide attempts to emerge.

Borderline personality disorder and emotion dysregulation

Borderline personality disorder (BPD) is a severe and complex disorder characterized by instability across many life domains, including interpersonal relations, behavior, and emotions. A core feature and contributor to BPD, emotion dysegulation (ED), consists of deficits in the ability to regulate emotions in a manner that allows the individual to pursue important goals or behave effectively in various contexts. Biosocial developmental models of BPD have emphasized a transaction of environmental conditions (e.g., invalidating environments and adverse childhood experiences) with key genetically linked vulnerabilities (e.g., impulsivity and emotional vulnerability) in the development of ED and BPD. Emerging evidence has begun to highlight the complex, heterotypic pathways to the development of BPD, with key heritable vulnerability factors possibly interacting with aspects of the rearing environment to produce worsening ED and an adolescent trajectory consisting of self-damaging behaviors and eventual BPD. Adults with BPD have shown evidence of a variety of cognitive, physiological, and behavioral characteristics of ED. As the precursors to the development of ED and BPD have become clearer, prevention and treatment efforts hold great promise for reducing the long-term suffering, functional impairment, and considerable societal costs associated with BPD.

Mental illness and well-being: an affect regulation perspective

Mental health crucially depends upon affective states such as emotions, stress responses, impulses and moods. These states shape how we think, feel and behave. Often, they support adaptive functioning. At other times, however, they can become detrimental to mental health via maladaptive affect generation processes and/or maladaptive affect regulation processes. Here, we present an integrative framework for considering the role of affect generation and regulation in mental illness and well-being. Our model views affect generation as an iterative cycle of attending to, appraising and responding to situations. It views affect regulation as an iterative series of decisions aimed at altering affect generation. Affect regulation decisions include identifying what, if anything, should be changed about affect, selecting where to intervene in the affect generation cycle, choosing how to implement this intervention, and monitoring the regulation attempt to decide whether to maintain, switch or stop it. Difficulties with these decisions, often arising from biased inputs to them, can contribute to manifestations of mental illness such as clinical symptoms, syndromes and disorders. The model has a number of implications for clinical assessment and treatment. Specifically, it offers a common set of concepts for characterizing different affective states; it highlights interactions between affect generation and affect regulation; it identifies assessment and treatment targets among the component processes of affect regulation; and it is applicable to prevention and treatment of mental illness as well as to promotion and restoration of psychological well-being.

A Recurrent Question: What Is Borderline?

The status of borderline personality disorder (BPD) as a diagnostic category is a matter of continuing controversy. In the United States, BPD is one of the most frequent diagnoses of psychiatric inpatients, and a similar tendency emerges in Europe. Nearly all theoretical aspects of BPD have been questioned, including its very position as a personality disorder. In this article, we trace the evolution of the borderline concept from the beginning of the 20th century to the current psychometric research. We argue that the status of BPD is fraught with conceptual difficulties, including an unrecognized semantic drift of major phenomenological terms (e.g., identity), a lack of general principles for the distinction of BPD and the major psychiatric syndromes (e.g., schizophrenia spectrum disorders), and insufficient definitions of key nosological concepts. These difficulties illustrate general problems in today's psychiatry that require consideration.

Implicit and explicit self-concept of neuroticism in borderline personality disorder

PURPOSE

In the past, research on personality in borderline personality disorder (BPD) used primarily questionnaires suggesting heightened neuroticism in BPD. Self-report instruments inform about the conscious or explicit self-concept. BPD patients are known to show negative distortion with exaggeration of negative affect in the self-report. Neuroticism represents a risk factor for mental disorders. Indirect measures are available that tap into the implicit self-concept of neuroticism. The implicit self-concept refers to individual differences in associative representations of the self. The present study examined for the first time the implicit in addition to the explicit self-concept of neuroticism in BPD.

MATERIALS AND METHODS

Female BPD patients (N = 35) and healthy women (N = 39) completed an implicit association test and the NEO-FFI personality inventory.

RESULTS

BPD patients showed higher implicit and explicit neuroticism compared to controls. The group difference for explicit neuroticism was four times larger than that for implicit neuroticism. Presence of comorbid depressive disorder was positively correlated with implicit neuroticism. The IAT neuroticism showed excellent split-half reliability for BPD patients.

CONCLUSIONS

The present data suggest that BPD patients with comorbid clinical depression but not those without clinical depression differ from healthy individuals in their implicit self-concept of neuroticism. In the associative network, BPD patients with comorbid clinical depression exhibit stronger associations of the self with neuroticism-related characteristics, such as nervousness, fearfulness, and uncertainty than healthy individuals. Regardless of depression, BPD patients show increased explicit neuroticism. Our findings provide evidence that the IAT neuroticism can be applied reliably to BPD patients.

Emotional Responsiveness in Borderline Personality Disorder: The Role of Basal Hyperarousal and Self-Reported Emotional Regulation

The present study aims to test the hypothesis of biological hyperarousal and hyperreactivity underpinning the dysfunctional emotional processes of borderline personality disorder (BPD). Self-reported (quality and intensity of emotions) and physiological (respiratory sinus arrhythmia [RSA] and heart rate) data were collected in 14 clinical subjects with BPD and in 14 control subjects (healthy controls [HCs]), during the administration of six video clips with different emotional contents. Our findings showed a constant hyperarousal state (lower RSA) in the clinical group, supporting the hypothesis of a biological vulnerability to emotional dysregulation. BPD patients showed lower self-reported happiness in positive stimuli compared with HCs and a significant association between emotional dysregulation and physiological hyperreactivity to neutral stimuli. Our data support the hypothesis of a constant condition of physiological preparedness to threat and danger in BPD subjects. Moreover, our results highlight the influence of self-reported ability in regulating emotions in explaining BPD responses to specific emotional situations.

Subjective emotional responses to IAPS pictures in patients with borderline personality disorder, cluster-C personality disorders, and non-patients

According to Linehan (1993), emotion dysregulation is a central feature of borderline personality disorder (BPD). We hypothesized that patients with BPD are emotionally hyperresponsive. For BPD treatment, it is important to evaluate this hypothesis, because, if it is supported, therapeutic interventions could be designed to help patients to better manage hyperemotional reactions. We investigated the subjective reactions (in terms of valence and arousal) of patients with BPD to visual emotional stimuli of the International Affective Picture System (IAPS). We hypothesized that, compared to patients with Cluster-C personality disorders and non-patients, BPD patients would show higher scores on the arousal dimension and higher negative scores on the valence dimension when rating IAPS pictures with varying degrees of arousal and valence. Ratings of valence and arousal for 40 IAPS pictures were collected from 39 borderline personality disorder (BPD), 36 patients diagnosed with Cluster-C personality disorders (PD), and a group of 226 non-patients. Contrary to expectations, BPD patients did not differ from the non-patients. This indicates that their self-report scores do not reflect hypersensitivity. We found that patients with BPD showed lower scores on arousal than Cluster-C PD patients. The scores on valence suggested that Cluster-C PD patients also experienced more positive emotions than BPD patients.

Crying in borderline personality disorder patients

Emotion dysregulation and hyperreactivity are considered central features of Borderline Personality Disorder (BPD). We assumed that such emotion dysregulation is also reflected in increased crying behavior of these patients and, consequently, hypothesized that BPD patients (N = 62), compared to Cluster C personality disorder patients (Cluster C-PD; N = 25) and non-patients (N = 54), would show higher scores on crying measures. To evaluate crying behavior, we used a set of specially designed tools. Compared to non-patients, BPD patients showed the anticipated higher crying frequency despite a similar crying proneness and ways of dealing with tears. They also reported less awareness of the influence of crying on others. However, Cluster C-PD patients showed a very similar pattern of findings. Overall, our results suggest that the increased crying of BPD patients likely results from environmental factors or the misperception of situations, rather than from stable traits. Remarkable is that the observed discrepancies in crying behavior compared to non-patients seem to be similar for Cluster-C PDs and BPD.

A comprehensive evaluation of emotional responsiveness in borderline personality disorder: a support for hypersensitivity hypothesis

BACKGROUND

Many experimental studies have evaluated Linehan's biological emotional vulnerability in Borderline Personality Disorder (BPD). However, some inconsistencies were observed in operationalizing and supporting its components. This study aims at clarifying which aspects of Linehan's model are altered in BPD, considering a multimodal evaluation of processes concerned with emotional responsiveness (self-report, psychophysiology and eye-tracking).

METHODS

Forty-eight socio-emotional pictures were administered to 28 participants (14 BPD, 14 Healthy Controls, HCs), gender- and age-matched, by employing two different lengths of stimuli exposure (5 s and 15 s).

RESULTS

Our results supported the hypersensitivity hypothesis in terms of faster physiological responses and altered visual processing. Furthermore, hypersensitivity was associated with detailed socio-emotional contents. Hyperreactivity assumption was not experimentally sustained by physiological and self-report data. Ultimately, the slow return to emotional baseline was demonstrated as an impaired emotional modulation.

CONCLUSIONS

Our data alternatively supported the hypersensitivity and the slow return to emotional baseline hypotheses, postulated by Linehan's Biosocial model, rather than the hyperreactivity assumption. Results have been discussed in light of other BPD core psychopathological processes.

A Neuroscience-Oriented Research Approach to Borderline Personality Disorder

Traditionally, the study of personality disorders had been based on psychoanalytic or behavioral models. Over the past two decades, there has been an emerging neuroscience model of borderline personality disorder (BPD) grounded in the concept of BPD as a condition in which dysfunctional neural circuits underlie its pathological dimensions, some of which include emotion dysregulation (broadly encompassing affective instability, negative affectivity, and hyperarousal), abnormal interpersonal functioning, and impulsive aggression. This article, initiated at a joint Columbia University- Cornell University Think Tank on BPD with representation from the Icahn School of Medicine at Mount Sinai, suggests how to advance research in BPD by studying the dimensions that underlie BPD in addition to studying the disorder as a unitary diagnostic entity. We suggest that linking the underlying neurobiological abnormalities to behavioral symptoms of the disorder can inform a research agenda to better understand BPD with its multiple presentations.

Borderline personality disorder symptoms and affective responding to perceptions of rejection and acceptance from romantic versus nonromantic partners

We examined event-contingent recording of daily interpersonal interactions in a diagnostically diverse sample of 101 psychiatric outpatients who were involved in a romantic relationship. We tested whether the unique effect of borderline personality disorder (BPD) symptoms on affective responses (i.e., hostility, sadness, guilt, fear, and positive affect) to perceptions of rejection or acceptance differed with one's romantic partner compared with nonromantic partners. BPD symptoms were associated with more frequent perceptions of rejection and less frequent perceptions of acceptance across the study. For all participants, perceptions of rejecting behavior were associated with higher within-person negative affect and lower within-person positive affect. As predicted, in interactions with romantic partners only, those with high BPD symptoms reported heightened hostility and, to a lesser extent, attenuated sadness in response to perceptions of rejection. BPD symptoms did not moderate associations between perceptions of rejection and guilt, fear, or positive affect across romantic and nonromantic partners. For all participants, perceived acceptance was associated with lower within-person negative affect and higher within-person positive affect. However, BPD symptoms were associated with attenuated positive affect in response to perceptions of accepting behavior in interactions with romantic partners only. BPD symptoms did not moderate associations between perceptions of acceptance and any of the negative affects across romantic and nonromantic partners. This study highlights the specificity of affective responses characteristic of BPD when comparisons are made with patients with other personality and psychiatric disorders. Implications for romantic relationship dysfunction are discussed. (PsycINFO Database Record

Treatment-induced brain plasticity in borderline personality disorder: review of functional MRI studies

Although neural substrates of symptoms expression in borderline personality disorder (BPD) have been studied extensively, neural mechanisms mediating post treatment amelioration of symptoms remain poorly characterized. Herein present review sheds a critical light on all here-to-date functional MRI findings of brain changes in BPD patients following a treatment with psychotherapy or drugs. Preliminary evidence points to downregulation of neuronal activity within the insula and amygdala, together with differential employment of prefrontal areas, mainly orbitofrontal cortex, anterior cingulate cortex and dorsolateral prefrontal cortex, as well as enhanced functional connectivity between limbic and prefrontal regions induced by dialectical behavioral therapy. Identifying neural circuits behind treatment processes may refine strategies to target specific symptoms, thereby resolving some of the controversies over BPD treatment.

Isolating the effect of opposite action in borderline personality disorder: A laboratory-based alternating treatment design

Evaluating the unique effects of each component included in treatment protocols for borderline personality disorder (BPD) is a necessary step in refining these interventions so that they only include skills that drive therapeutic change. One strategy, included in several prominent treatments for BPD, is acting opposite to emotion-driven behavioral urges; engaging in behaviors that are inconsistent with an experienced emotion is thought to lead to reductions in its intensity, though this has not been empirically-tested. The present study was a single-case experiment, specifically an alternating treatment design, that explored the effects of a laboratory-based adaptation of opposite action (versus acting consistent) on emotional intensity. Sixteen individuals with BPD attended six laboratory sessions in which they were instructed to act consistent with an induced emotion in half the sessions and opposite in the other half. Participants were randomly assigned to the specific emotion (i.e., anxiety, sadness, anger, and shame/guilt) that was induced across all study sessions. Findings from visual inspection and percentage of non-overlapping data suggest that acting opposite (versus consistent) leads to significantly greater decreases in emotional intensity for those in the sadness and guilt/shame conditions, but not those in the anxiety or anger conditions. Possible interpretations of these findings are presented. Replication outside of the laboratory context is necessary to draw further conclusions of the clinical implications of these findings.

Are emotional action tendencies and attentional bias related to temperament dimensions in patients with borderline personality disorder?

Disturbances in emotion regulation have been identified as a core feature of patients with a borderline personality disorder (BPD). Findings of studies using experimental measures of emotion processing are mixed, which may be partially explained by the heterogeneity of the BPD population. To address this issue, we investigated differences in experimental measures of emotional action tendencies (approach-avoidance behaviour) and attentional bias to emotional stimuli in BPD subtypes. Data of the Approach-Avoidance Task (AAT) and the Emotional Stroop Task (EST) were collected in 140 BPD patients, previously clustered into four BPD subtypes based on temperament dimensions. We investigated (1) the relationship between temperament dimensions and the performance on the AAT and EST and (2) compared performance on these tasks in previous defined BPD subtypes. The results of the present study demonstrated a positive relationship between effortful control (EC) and AAT effect-scores. A higher level of EC was positively associated with a general emotional action tendency towards faces with directed gaze, even when controlling for gender, age and BPD severity. Preliminary results on the comparison of the BPD subtypes demonstrated no significant differences in AAT and EST performance. These findings emphasize the relevance of EC in emotional action tendencies in BPD patients.

Borderline personality disorder affective instability: What you know impacts how you feel

The current study examined the role of conceptual knowledge and language in affective instability (AI) associated with borderline personality disorder (BPD). Forty-six females meeting criteria for BPD and 51 nonclinical female control participants without BPD completed a measure of general vocabulary and a semantic similarities task that provided estimates of the degree to which participants weighted information about valence and arousal in their understanding of emotion language. Feelings of valence and arousal were assessed using the Self-Assessment Manikin in response to 62 emotionally evocative images, which was used to derive estimates of AI. BPD status was associated with valence and arousal AI at a bivariate level, but not after controlling for language variables (general vocabulary and semantic valence and arousal foci). Participants with stronger as opposed to weaker vocabularies exhibited less AI, and participants who emphasized arousal more in their conceptual representations of emotions exhibited less AI than those who emphasized it to a lesser degree. With the inclusion of language variables in a regression equation with BPD status predicting AI, semantic arousal focus, but not general vocabulary, was a significant predictor of AI. Consistent with psychological constructionist models of emotion that specify an active role of language throughout the emotion generation process, these findings suggest that language capacity (general vocabulary and the degree to which arousal influences understanding of emotion words) is an important determinant of the AI associated with BPD.

Models of borderline personality disorder: recent advances and new perspectives

PURPOSE OF REVIEW

The purpose of this article is to review the most relevant conceptual models of borderline personality disorder (BPD), with a focus on recent developments in this area.

RECENT FINDINGS

Several conceptual models have been proposed with the aim of better understanding BPD: the borderline personality organization, emotion dysregulation, reflective (mentalization) dysfunction, interpersonal hypersensitivity and hyperbolic temperament models. These models have all been supported to some extent and their common components include disorganized attachment and traumatic early experiences, emotion dysregulation, interpersonal sensitivity and difficulties with social cognition. An attempt to integrate some components of the conceptual models of BPD has resulted in an emerging new perspective, the interpersonal dysphoria model, which emphasizes dysphoria as an overarching phenomenon that connects the dispositional and situational aspects of BPD.

SUMMARY

Various conceptual models have expanded our understanding of BPD, but it appears that further development entails theoretical integration. More research is needed to better understand interactions between various components of BPD, including the situational factors that activate symptoms of BPD. This will help develop therapeutic approaches that are more tailored to the heterogeneous psychopathology of BPD.

Emotional reactivity to appraisals in patients with a borderline personality disorder: a daily life study

BACKGROUND

Emotional instability, consisting of patterns of strong emotional changes over time, has consistently been demonstrated in daily life of patients with a borderline personality disorder (BPD). Yet, little empirical work has examined emotional changes that occur specifically in response to emotional triggers in daily life, so-called emotional reactivity. The goal of this study was to examine emotional reactivity in response to general emotional appraisals (i.e. goal congruence or valence, goal relevance or importance, and emotion-focused coping potential) and BPD-specific evaluations (trust and disappointment in self and others) in daily life of inpatients with BPD.

METHODS

Thirty inpatients with BPD and 28 healthy controls participated in an experience sampling study and repeatedly rated the intensity of their current emotions, emotional appraisals, and evaluations of trust and disappointment in self and others.

RESULTS

Results showed that the BPD group exhibited stronger emotional reactivity in terms of negative affect than healthy controls, however only in response to disappointment in someone else. BPD patients also showed weaker reactivity in positive affect in response to the appraised importance of a situation; the more a situation was appraised as important, the higher the subsequent positive affect for healthy controls only, not the patient group.

CONCLUSIONS

These findings show that appraisals can trigger strong emotional reactions in BPD patients, and suggest that altered emotional reactivity might be a potential underlying process of emotional instability in the daily life.

Reconsidering Emotion Dysregulation

This article aims to review the concept of emotion dysregulation, focusing on issues related to its definition, meanings and role in psychiatric disorders. Articles on emotion dysregulation published until May 2016 were identified through electronic database searches. Although there is no agreement about the definition of emotion dysregulation, the following five overlapping, not mutually exclusive dimensions of emotion dysregulation were identified: decreased emotional awareness, inadequate emotional reactivity, intense experience and expression of emotions, emotional rigidity and cognitive reappraisal difficulty. These dimensions characterise a number of psychiatric disorders in various proportions, with borderline personality disorder and eating disorders seemingly more affected than other conditions. The present review contributes to the literature by identifying the key components of emotion dysregulation and by showing how these permeate various forms of psychopathology. It also makes suggestions for improving research endeavours. Better understanding of the various dimensions of emotion dysregulation will have implications for clinical practice. Future research needs to address emotion dysregulation in all its multifaceted complexity so that it becomes clearer what the concept encompasses.

Self and informant report across the borderline personality disorder spectrum

Individuals with borderline personality disorder (BPD) features may be unaware of or unwilling to report their own personality or maladaptive behaviors, which complicates the assessment of BPD. Informants who know the individuals with BPD features may be uniquely suited to aid in the personality assessment of these individuals. The present study analyzed the comparative ability of individuals (targets) and informants to report BPD features across the continuum of BPD severity. The sample consisted of 1387 targets, ages 55 to 65 (56% women), who were recruited for an epidemiological longitudinal study examining the effects of PDs on health and social functioning. Each target nominated an informant who provided information about the target's personality. Results indicated relatively low levels of agreement between perspectives and that informants reported BPD symptoms with more precision and at lower levels of BPD severity than targets. The benefits of including an informant perspective when measuring the BPD continuum are discussed; these benefits may include gains in reliability and improvement in the prediction of outcomes.

Emotion Dysregulation Mediates the Relation Between Borderline Personality Disorder Symptoms and Later Physical Health Symptoms

Despite evidence of a relation between borderline personality disorder (BPD) pathology and physical health problems, the mechanisms underlying this relation remain unclear. Given evidence that emotion dysregulation may affect physical health by altering physiological functioning, one mechanism that warrants examination is emotion dysregulation. This study examined BPD symptoms as a prospective predictor of physical health symptoms 8 months later and the mediating role of emotion dysregulation in this relation. Participants completed three assessments over an 8-month period, including a BPD diagnostic interview. Results of analyses examining baseline predictors of later physical health symptoms revealed a significant unique association between baseline BPD symptom severity and physical health symptoms 8 months later, above and beyond baseline physical health symptoms, depression and anxiety symptoms, and emotion dysregulation. Moreover, structural equation modeling revealed a significant indirect relation of BPD symptoms at Wave 1 to physical health symptoms at Wave 3 through emotion dysregulation at Wave 2.

Borderline Personality Disorder and the Effects of Instructed Emotional Avoidance or Acceptance in Daily Life

This study examined the effects of avoidance- versus acceptance-oriented emotion regulation instructions among individuals with borderline personality disorder (BPD; n = 48), major depressive disorder (MDD; n = 54), and non-psychiatric controls (NPC; n = 50) using ecological momentary assessment. Participants were randomly assigned to either accept or avoid negative emotions, and monitored their moods, urges, and distress tolerance several times per day over 6 days. Avoidance instructions resulted in reduced negative affect and urges for maladaptive behaviors uniquely among BPD participants. Together with past research, and consistent with treatment approaches emphasizing the short-term use of skills to avoid or distract from emotions (e.g., DBT; Linehan, 1993b, 2015), these findings suggest that avoidance of negative emotions may have temporary benefits for individuals with BPD. Acceptance-oriented strategies may take longer or may require more extensive training to be beneficial for emotional functioning in everyday life in BPD.

Facing the Problem: Impaired Emotion Recognition During Multimodal Social Information Processing in Borderline Personality Disorder

Previous research has revealed alterations and deficits in facial emotion recognition in patients with borderline personality disorder (BPD). During interpersonal communication in daily life, social signals such as speech content, variation in prosody, and facial expression need to be considered simultaneously. We hypothesized that deficits in higher level integration of social stimuli contribute to difficulties in emotion recognition in BPD, and heightened arousal might explain this effect. Thirty-one patients with BPD and thirty-one healthy controls were asked to identify emotions in short video clips, which were designed to represent different combinations of the three communication channels: facial expression, speech content, and prosody. Skin conductance was recorded as a measure of sympathetic arousal, while controlling for state dissociation. Patients with BPD showed lower mean accuracy scores than healthy control subjects in all conditions comprising emotional facial expressions. This was true for the condition with facial expression only, and for the combination of all three communication channels. Electrodermal responses were enhanced in BPD only in response to auditory stimuli. In line with the major body of facial emotion recognition studies, we conclude that deficits in the interpretation of facial expressions lead to the difficulties observed in multimodal emotion processing in BPD.
