Interpersonal stressors and negative affect in individuals with borderline personality disorder and community adults in daily life: A replication and extension

Momentary Dynamics Implicate Emotional Features in the ADHD Phenotype

Emotional dysregulation is increasingly recognized as important to the attention-deficit/hyperactivity disorder (ADHD) phenotype alongside inattention and hyperactivity-impulsivity. Studies of ADHD have relied primarily on trait-based conceptualizations that emphasize stability of symptoms across moderate developmental timescales (i.e., months to years). Trait-based conceptualizations provide a critical view but fail to account for short-term dynamic variations in the expression of ADHD symptoms and emotion. This leaves a gap in our understanding of the short-term variation in ADHD symptom expression and the dynamic relationships among ADHD symptoms and emotion. Here, we assessed caregiver report of ADHD symptoms and positive and negative emotion using ecological momentary approaches over 2 weeks in a sample of 36 children with and without ADHD between the ages of 7-12 years old. Between-person (RKF) and within-person (RC) reliability were estimated. Multilevel models tested specific covariation hypotheses between ADHD symptoms and emotion. Analyses confirmed that ADHD and emotion ratings were reliable as individual differences (i.e., between-person; RKF range 0.93-1.0) and moment-to-moment change (i.e., within-person; Rc range 0.66-0.88) measures. Multilevel models found little evidence for lagged effects between domains, but consistently identified concurrent expression of ADHD symptoms and emotions; inattention covaried most strongly with negative emotion and hyperactivity-impulsivity covaried most strongly with positive emotion. Results demonstrate the importance of complementing trait-level conceptualizations with assessment of momentary dynamics. Momentary assessment suggests important covariation of ADHD symptoms and emotion as part of the ADHD phenotype.

Shame, suicidal ideation, and urges for non-suicidal self-injury among individuals with borderline personality disorder receiving dialectical behavior therapy: The mediating role of anger

INTRODUCTION

Borderline personality disorder (BPD) is a disorder of pervasive emotion dysregulation associated with high rates of self-injurious thoughts and behaviors (SITB). Understanding specific emotion states in relation to SITB is important for effective intervention.

METHODS

The current study examined whether, and how, the specific emotion of shame contributes to suicide ideation and urges to engage in non-suicidal self-injury (NSSI) both directly, and indirectly via anger, among individuals with BPD. Participants (N = 100) were enrolled in a 6-month comprehensive dialectical behavior therapy (DBT) program and provided daily ratings of shame, anger, suicide ideation, and urges for NSSI.

RESULTS

We found that higher daily ratings of shame and anger were directly associated with higher same-day ratings of both suicidal ideation and urges for NSSI. Furthermore, anger partially mediated the relationships between shame and both suicidal ideation and urges for NSSI.

CONCLUSION

These findings highlight shame and anger as potential antecedents of SITB among individuals with BPD. Clinical approaches, such as DBT, that include personalized, ongoing, clinical assessment of these specific affective states may be particularly important for treatment of SITB.

Assessing Measurement Consistency: A Study of the BPFSC Invariance Across Age and Sex in Romanian Adolescents

The Borderline Personality Feature Scale for Children (BPFSC) is a widely used instrument and currently the only dimensional measure to investigate Borderline Personality features in children and adolescents. The present study aimed to investigate the factor structure and measurement invariance across age and sex in a community sample of 634 adolescents (mean age = 16.72, standard deviation = 1.31). To test for measurement invariance, we conducted multi-group confirmatory factor analysis (MG-CFA). Analysis showed residual invariance across age and sex. Based on the results, we conclude that BPFSC is a valid and reliable instrument to assess Borderline Personality features in adolescents. Implications for evidence-based assessment of Borderline Personality features in adolescence are discussed.

Borderline personality features are associated with worse perceptions of (but not compliance with) chronic pain treatment

Treating chronic illness requires ongoing patient-provider cooperation, but individual differences in patients' negative perceptions of care can undermine this cooperation. Research suggests people high on borderline personality disorder (BPD) features may react negatively to and comply less with mental health and medical treatment. This might be particularly problematic in chronic pain treatment, where BPD features are over-represented and the dysregulation typifying BPD likely undermines consistent care. In a sample of 147 chronic pain patients, we investigated whether higher levels of BPD features - both in general and by specific facets - predicted worse perceptions of treatment and lower patient-reported compliance with treatment recommendations. Participants higher (vs. lower) on borderline features viewed treatment more negatively but did not report complying less with recommendations. We found evidence that this may reflect the unstable relationships facet of BPD. Our results indicate that, consistent with other treatment settings, BPD features may undermine care for chronic pain. Furthermore, our results highlight the importance of collaborative provider-patient relationships and patient agreement with the treatment of chronic pain, particularly among individuals higher on BPD features.

"I'm fighting with BPD instead of my partner": A dyadic interpretative phenomenological analysis of the lived experience of couples navigating borderline personality disorder

Borderline personality disorder (BPD) is associated with romantic relationship distress and dissolution. The complex interaction between BPD and romantic relationships warrants further attention. Dyadic interviews (N = 10) were conducted to examine the experience and impact of BPD on couples' relationships. The results of interpretative phenomenological analysis consisted of two superordinate themes describing the couple experience of navigating BPD: (a) the shared experience of BPD as a relational stressor; and (b) adaptive dyadic coping in the context of BPD. Although BPD was experienced as a relational stressor, dyadic coping and shared externalization of BPD emerged as central components to adaptive couple functioning. Most couples reported that therapy was a critical external resource in their journey toward adaptively functioning in the context of BPD, both intrapersonally and interpersonally. The lived experiences of these couples provides therapists with an increased understanding of the resources that support adaptive dyadic coping with BPD.

Modulation of Trust in Borderline Personality Disorder by Script-Based Imaginal Exposure to Betrayal

Interpersonal and trust-related difficulties are central features of borderline personality disorder (BPD). In this study, we applied script-driven betrayal imagery to evoke mistrustful behavior in a social reinforcement learning task. In 21 BPD and 20 healthy control (HC) participants, we compared this approach to the standard confederate paradigm used in research studies. The script-driven imagery evoked a transient increase in negative affect and also decreased trusting behavior to a similar degree in both groups. Across conditions, we also replicated previously reported between-group differences in negative affect (increased in BPD) and task behavior (more sensitive to social cues in BPD). These results support the validity of script-driven imagery as an alternative social task stimulus. This script-driven imagery approach is appealing for clinical research studies on reinforcement learning because it eliminates deception, scales easily, and evokes disorder-specific states of social difficulty.

Negative affect provides a context for increased distrust in the daily lives of individuals with a history of childhood maltreatment

Evidence on individuals affected by posttraumatic stress disorder (PTSD) following childhood maltreatment (CM) supports cognitive models suggesting that trauma engenders distrust and interpersonal threat sensitivity. We examined the associations between CM and both distrust and interpersonal threat sensitivity in daily life and investigated whether momentary negative affect (NA) provides a context that strengthens this association. Hypotheses were based on cognitive models of trauma and the feelings-as-information theory. In a 7-day ambulatory assessment study with six semirandom daily prompts (2,295 total), we measured self-reported momentary NA and assessed behavioral trust as well as interpersonal threat sensitivity via facial emotion ratings with two novel experimental paradigms in 61 participants with varying levels of CM (45,900 total trials). As hypothesized, NA was associated with increased momentary distrust, β = .03, p = .002, and interpersonal threat sensitivity, β = -.01, p = .021. Higher levels of CM were associated with more negative emotion ratings, independent of affective context, β = -.07, p = .003. Momentary behavioral distrust was associated with CM at high levels of momentary NA, β = .02, p = .027. The findings for both tasks support the feelings-as-information theory and suggest that cognitive alterations surrounding distrust and interpersonal threat, which were originally proposed for PTSD, likely also affect individuals with a history of CM.

Operationalizing undifferentiated affect: Validity and utility in clinical samples

Emotion differentiation is conceptualized as the process of categorizing one's general affective experiences into discrete emotions. The experience of undifferentiated affect or the inability to distinguish the particular emotion or combination of emotions that one is experiencing is often considered a hallmark of emotion dysregulation. Some past research has attempted to operationalize the general tendency to experience undifferentiated affect at the trait level using explicit questionnaire measures. More recently, indirect measures using intraclass correlation coefficients (ICCs) to estimate the consistency between simultaneous measures of different in-the-moment emotional experiences have become the favored method of quantifying undifferentiated affect. While the ICC method constitutes an advancement in estimating undifferentiated affect, which is theorized to be a dynamic process that occurs at a very granular level, prior investigations have used aggregate ICC measures or momentary ICC derivations that ignore multiple sources of dynamic variability to make inferences about in-the-moment experiences. We introduce a new, flexible method of calculating ICC measures of undifferentiated affect at different levels of experience that takes full advantage of time-intensive data measurement and more closely maps onto the theorized process. This method provides more refined estimates of undifferentiated affect and its associations with various behavioral outcomes, as well as uncovers more nuanced associations regarding the temporal process of emotional differentiation. It also elucidates potential conceptual issues in mapping empirical estimates of emotion undifferentiation onto their underlying theoretical interpretations.

What If I Feel Rejected? Borderline Personality, Pathological Narcissism, and Social Rejection in Daily Life

The authors investigate whether and how borderline and pathological narcissistic traits differ in their associations with trait and state rejection sensitivity, and with affective reactions to experiences of social rejection occurring in daily life. Community adults (N = 189) completed baseline measures of rejection sensitivity, borderline personality, and pathological narcissism, and daily measures of perceived social rejection and affective states for 7 days. Vulnerable narcissism was the main driver of negative anticipated emotions for social rejection. Borderline personality made people prone to experiencing social rejection in daily life. Moreover, borderline personality traits predicted greater self-directed aggressive impulses when experiencing social rejection. Grandiose narcissism showed only a negative association with anticipatory anxiety for rejection. These findings highlight that sensitivity to social rejection is crucial in both borderline personality and pathological narcissism.

Momentary interpersonal processes of suicidal surges in borderline personality disorder

BACKGROUND

Suicide rates are high in borderline personality disorder (BPD) where interpersonal problems trigger intense affective dysregulation and impulses to act on suicidal thoughts. To date, however, no study has examined how interpersonal stressors contribute to momentary within-person links among affect and impulsivity with suicidal ideation (SI), and how those links vary over time in people's daily lives.

METHODS

A total of 153 individuals diagnosed with BPD and 52 healthy controls completed a 21-day ecological momentary assessment protocol. Of these 153 individuals with BPD, 105 had a history of suicide attempts. Multilevel structural equation modeling was used to examine dynamic links among interpersonal perceptions, affect, state impulsivity, and suicidal intent.

RESULTS

Aggregated across interactions, lower perceived warmth in others was associated with SI. This direct relationship, however, did not extend to momentary within-person associations. Instead, interpersonal conflicts were linked to SI indirectly via greater negative affect and lower positive affect. While a robust within-person link between interpersonal perceptions and impulsivity emerged, impulsivity did not account for the relationship between interpersonal perceptions and SI.

CONCLUSION

This intensive longitudinal study illustrates momentary interpersonal signatures of an emerging suicidal crisis. Among people with BPD at high risk for suicide, interpersonal triggers initiate a cascade of affective dysregulation, which in turn gives rise to SI.

The roles of personality traits and close social contact in the expression of momentary borderline personality disorder symptoms in daily life

Dimensional models of personality, such as the five-factor model (FFM), have demonstrated strong coherence with the presentation of personality disorders, including borderline personality disorder (BPD). Given that select personality trait elevations have been linked to impairments in multiple life domains across diagnostic groups, we sought to replicate findings from a previous investigation of the utility of the FFM in predicting BPD-relevant outcomes (i.e., negative affect intensity and instability, impulsivity, and interpersonal disagreements) in the daily lives of those with BPD (Hepp et al., 2016) and community participants. As interpersonal context is instrumental in determining the strength of effects observed in studies examining individuals with BPD, we utilized ecological momentary assessment across 3 weeks (6 times daily; ntotal = 15,889) to test whether close social contact (CSC) would moderate the effects of personality on momentary outcomes. Overall, results suggest that CSC is an important moderator between the effects of personality and daily life outcomes for individuals with BPD (N = 56), but not for community individuals (N = 60). For individuals with BPD, CSC may function as both a protective buffer and a risk factor, depending on outcome. For example, CSC attenuates experience of negative affect intensity for individuals with elevated neuroticism, but CSC may predict more frequent disagreements for individuals who report lower agreeableness. We replicated approximately half of the original study's findings, and results support that FFM personality is predictive of BPD-relevant outcomes broadly. However, interpersonal context is key to understanding these relationships for individuals with BPD. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Negative affectivity and disinhibition as moderators of an interpersonal pathway to suicidal behavior in borderline personality disorder

This longitudinal study examined whether personality traits moderate the link between interpersonal dysfunction and suicidal behavior in a high-risk sample of 458 individuals diagnosed with borderline personality disorder (BPD). Participants were assessed annually for up to 30 years (mean number of follow-ups = 7.82). Using multilevel structural equation modeling, we examined i) longitudinal, within-person relationships among interpersonal dysfunction, suicidal ideation, and suicide attempts; and ii) moderation of these relationships by negative affectivity and disinhibition. Negative affectivity predicted a stronger within-person coupling between interpersonal dysfunction and suicidal ideation. Disinhibition predicted a stronger coupling between ideation and suicide attempts. Assessing negative affectivity and disinhibition in a treatment setting may guide clinician vigilance toward those at highest risk for interpersonally triggered suicidal behaviors.

Transdiagnostic Associations With Interpersonal and Affective Variability in Borderline Personality Pathology

Emotional and behavioral variability are unifying characteristics of borderline personality disorder (BPD). Ambulatory assessment (AA) has been used to quantify this variability in terms of the categorical BPD diagnosis, but evidence suggests that BPD instead reflects general personality pathology. This study aimed to clarify the conceptualization of BPD by mapping indices of variability in affect, interpersonal behavior, and perceptions of others onto general and specific dimensions of personality pathology. A sample of participants who met diagnostic criteria for BPD (n = 129) and healthy controls (n = 47) reported on their daily interactions during a 21-day AA protocol. Multilevel SEM was used to examine associations between shared and specific variance in maladaptive traits with dynamic patterns of functioning. The authors found that variability is an indicator of shared trait variance and Negative Affectivity, not any other specific traits, reinforcing the idea that BPD is best understood as general personality pathology.

THE EXPERIENCE OF SOCIAL DISTANCING IN PATIENTS BPD SUBTYPE RELATIONAL DYSREGULATION DURING THE FIRST WAVE COVID-19 PANDEMIC LOCKDOWN. A CASES SERIES

The infectious disease SARS-CoV-2 or Coronavirus 19 (COVID-19) has generated a clear psychosocial impact, affecting general populations’ physical and mental health. This impact derives from the pandemic itself and the associated restriction measures implemented. Regarding Spain, a home lockdown was imposed from May 15th to June 20th through the declaration of the National State of Alarm. The impact on general populations’ mental health has been great in Catalunya, our zone, where anxiety levels have multiplied by four and depressive levels by three compared to before the lockdown.

The influence of narcissistic vulnerability and grandiosity on momentary hostility leading up to and following interpersonal rejection

Wide empirical support exists for 2 aspects of narcissism-grandiosity and vulnerability. Hostility is a form of interpersonal antagonism, which is considered central to narcissism broadly. Though it has often been subsumed by the concept of narcissistic grandiosity, interpersonal antagonism is associated with vulnerability as well. Rejection represents an interpersonal stressor that evokes hostility to a greater degree in those high in narcissism, with mixed evidence regarding whether it stems from threat to one's egotism (grandiosity) or low self-esteem (vulnerability). Therefore, investigating the associations between narcissistic dimensions and individuals' trajectories of hostility leading up to and following rejection may provide a basis for a more unified conceptualization. In this study, we leverage the wide range of narcissistic expression displayed in a combined sample of borderline personality disorder (N = 56) and community (N = 60) individuals who completed ambulatory assessments approximately 6 times per day for 21 consecutive days. We examine whether narcissistic vulnerability and grandiosity, as measured by NEO Personality Inventory facet combinations constructed based on the Five-Factor Narcissism Inventory, moderate trajectories and overall levels of hostility surrounding self-reported interpersonal rejections. Grandiosity and vulnerability were independently positively associated with a faster rise in hostility leading up to rejection; however, greater grandiosity was uniquely associated with a greater spike in hostility at the occasion of rejection and subsequent faster recovery. These results are consistent with both the idea that grandiosity is proportionately more central to interpersonal antagonism and that antagonism serves as a bridge, connecting and reinforcing both narcissistic grandiosity and vulnerability.

Relations between lab indices of emotion dysregulation and negative affect reactivity in daily life in two independent studies

BACKGROUND

We investigated the extent to which physiological/biological measures of emotion dysregulation collected in the lab, resting respiratory sinus arrhythmia (RSA) in Study 1 and amygdala activation in response to negative stimuli in Study 2, combined with daily measures of interpersonal stressors predicted negative emotional states in outpatients better than the stressors alone.

METHODS

Participants were adult outpatients with emotional distress disorders (N=30 individuals in Study 1, and N=26 women in Study 2). After completing a laboratory session that collected physiological/biological measures of emotion dysregulation, participants then completed 1-3 weeks of ambulatory assessment during which they reported on interpersonal stressors and negative affective states several times per day.

RESULTS

Laboratory measures of emotion dysregulation were largely unrelated to either momentary or mean levels of daily-life hostility, sadness, and fear in both studies. However, resting RSA significantly moderated the association between day-level interpersonal stressors and momentary fear such that low resting RSA strengthened this association. Similarly, amygdala activation tended to moderate this relationship in the predicted direction.

LIMITATIONS

Both samples were relatively small and focused on only a limited set of diagnoses associated with emotion dysregulation. Only two possible physiological/biological markers of emotion dysregulation were examined.

CONCLUSIONS

The current studies support the collection of physiological/biological data on emotion dysregulation when indexing daily-life emotion dysregulation as the degree of emotional reactivity to stressors in daily life among outpatients with emotional distress disorders.

Positive Affect Is Associated With Decreased Symptom Severity in the Daily Lives of Individuals With Borderline Personality Disorder

Previous research has repeatedly demonstrated positive associations between negative affect (NA) and borderline personality disorder (BPD) symptoms in daily life, but studies have rarely addressed potential effects of positive affect (PA). Consequently, little is known about how PA in daily life covaries with symptoms of BPD. The authors assessed the effects of both PA and NA levels on BPD symptom severity in a sample of 81 treatment-seeking women diagnosed with BPD over a period of 21 days, employing a daily diary design. Using multivariate multilevel modeling, the authors obtained negative associations between PA levels and daily BPD severity in total and at the level of the individual symptoms inappropriate anger, affective instability, emptiness, identity disturbance, and paranoid ideation/dissociation. Moreover, the authors replicated previously reported positive associations between NA and BPD severity for all nine symptoms. Future research can address whether increasing PA in the treatment of BPD may potentially help reduce symptom burden.

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.

Investigating the stress-related fluctuations of level of personality functioning: A critical review and agenda for future research

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the International Classification of Diseases (ICD-11) proposed a dimensional approach to the assessment of personality disorders (PDs). Both models dictate that the clinician first determines PD severity before assessing maladaptive traits, invoking the level of personality functioning (LPF) construct. We consider LPF a promising dimensional construct for translational research because of its clinical importance and conceptual overlap with the Research Domain Criteria (RDoC) Social Processes. We aim to identify biomarkers that co-vary with fluctuations in LPF in adulthood, ultimately to predict persistent decrease in LPF, associated with suicidality and morbidity. However, a theoretical framework to investigate stress-related oscillations in LPF is currently missing. In this article, we aim to fill this hiatus with a critical review about stress and LPF. First, we discuss acute stress and LPF. We briefly present the basics of the neurophysiological stress response and review the literature on momentary and daily fluctuations in LPF, both at a subjective and physiological level. Second, we review the effects of chronic stress on brain function and social behaviour and recapitulate the main findings from prospective cohort studies. This review underlies our suggestions for multimethod assessment of stress-related oscillations in LPF and our theoretical framework for future longitudinal studies, in particular studies using the experience sampling method (ESM).

The environmental, interpersonal, and affective context of nonsuicidal self-injury urges in daily life

Urges for nonsuicidal self-injury (NSSI) are important precursors to NSSI acts and may serve as a point of intervention. A close understanding of the phenomenology of NSSI urges and the contexts in which they occur is therefore warranted. We used ambulatory assessment to examine the environmental, interpersonal, and affective contexts of NSSI urges. We recruited 56 participants with borderline personality disorder who reported on urges and contexts for 21 days with six random daily prompts, resulting in 5,750 completed assessments. Twenty-two participants reported 160 NSSI urges. We provide extensive descriptive results characterizing the interaction partners, activities, and events participants reported in association with NSSI urges. Results from a logistic multilevel model using the full sample (testing associations between all contexts and urges simultaneously) revealed that urges were more likely to occur at higher levels of negative affect, when rejection was experienced, and later in the day. Urges were not associated with disagreements or feeling let down, being at home versus away, being alone versus in company, socializing versus doing another activity, and it being a weekday versus weekend. Additional growth curve analysis for negative affect using the subsample of 22 participants who reported urges showed that, over the course of urge days compared with nonurge days, negative affect increased before urges, peaked during the urge, and then decreased, approximating a quadratic curve. We conclude that urges occurred primarily in the context of negative affect and rejection, which is consistent with theories on intra- and interpersonal functions of NSSI.

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.

Linking Daily-Life Interpersonal Stressors and Health Problems Via Affective Reactivity in Borderline Personality and Depressive Disorders

OBJECTIVE

Borderline personality disorder (BPD) is associated with unstable interpersonal relationships, affective instability, and physical health problems. In individuals with BPD, intense affective reactions to interpersonal stressors may contribute to the increased prevalence of health problems.

METHODS

BPD (n = 81) and depressed participants (DD; n = 50) completed six daily ambulatory assessment prompts for 28 days. At each prompt, participants reported interpersonal stressors (disagreements, rejections, feeling let down), negative affect, and health problems in four domains (gastrointestinal, respiratory, aches, depressive symptoms). In multilevel moderated mediation models, we examined the indirect effects of interpersonal stressors on health problems via negative affect, by group.

RESULTS

Interpersonal stressors were positively associated with negative affect in both groups (β values > 0.12, p values < .001), but more so for participants with BPD (βDay = 0.05, p < .001). Negative affect was positively associated with health problems across all domains (βMoment/Day values > 0.01, p values < .046), but associations were larger at the day level for respiratory symptoms in BPD (β = 0.02, p = .025) and for depressive symptoms in DD (β = 0.04, p < .001). Negative affect mediated the association of interpersonal stressors and health problems in both groups, with larger effects for the DD group for depressive problems (β = 0.02, p = .092) and for the BPD group for the other three domains (β values > 0.02, p values < .090).

CONCLUSIONS

Interpersonal stressors may contribute to increased physical health problems via an inability to regulate affective responses to such events. This pathway may be stronger in several health domains for those with BPD and may contribute to an elevated risk of morbidity and mortality in this disorder, suggesting a target for intervention to reduce these risks.
