The borderline diagnosis I: psychopathology, comorbidity, and personaltity structure

Borderline personality disorder (BPD) is a complex and serious mental disorder associated with severe functional impairment, substantial treatment utilization, and a high rate of mortality by suicide. Recently, BPD has become a focus of intensifying study. In Part I of this three-part article meant to provide a foundation to researchers on the current status of the borderline diagnosis and prospects for its future development, we examine the psychopathology, comorbidity, and personality structure of BPD. Although the descriptive characteristics of BPD are well-represented by DSM-IV diagnostic criteria, other important aspects of BPD psychopathology are not included. The descriptive criteria in conjunction with semistructured interviews have, however, increased the ability of investigators to diagnose BPD as reliably as many Axis I disorders. Frequent comorbidity of BPD with Axis I disorders necessitates a broad assessment of psychopathology to help account for clinical heterogeneity. Because of the absence of evidence of the validity of the diagnostic threshold for a categorical diagnosis of BPD, and because of the heterogeneity within the diagnosis, investigators should also supplement their DSM-IV diagnoses with assessments of underlying personality trait structures. Although there are a number of competing models of personality structure, they have remarkable convergence on a set of three to five basic personality dimensions.

The Collaborative Longitudinal Personality Disorders Study: baseline Axis I/II and II/II diagnostic co-occurrence.

Objective: To describe baseline diagnostic co‐occurrence in the Collaborative Longitudinal Personality Disorders Study.

Childhood experiences of borderline patients.

The childhood histories of 50 outpatients meeting both Diagnostic Interview for Borderlines (DIB) and DSM-III criteria for Borderline Personality Disorder, 29 outpatients meeting DSM-III criteria for Antisocial Personality Disorder, and 26 outpatients meeting DSM-III for Dysthymic Disorder as well as DSM-III criteria for some other type of Axis II disorder were assessed, blind to proband diagnosis, using a semistructured interview. Borderlines were significantly more likely than those in either control group to report a history of abuse, particularly verbal and sexual abuse. They were also significantly more likely than antisocial controls to report a history of neglect, particularly emotional withdrawal, and significantly more likely than dysthymic other personality disorder controls to report a history of early separation experiences. The authors conclude that the development of Borderline Personality Disorder is more strongly associated with (1) exposure to chronically disturbed caretakers than prolonged separations from these same adults and (2) a history of abuse than a history of neglect.

An experimental investigation of emotion dysregulation in borderline personality disorder.

Despite the prominent role of emotion dysregulation in theoretical accounts of borderline personality disorder (BPD), few studies have examined emotion dysregulation in BPD. This study extends extant research by providing an experimental investigation of emotion dysregulation among outpatients with BPD. Specifically, this study modified an experimental measure of distress tolerance to examine differences between outpatients with BPD (n = 17) and those without a personality disorder (n = 18) in 2 aspects of emotion dysregulation: (a) the unwillingness to experience emotional distress in order to pursue goal-directed behavior and (b) the inability to engage in goal-directed behavior when distressed. As hypothesized, BPD participants were less willing to experience distress in order to pursue goal-directed behavior. However, BPD participants did not evidence greater difficulties engaging in goal-directed behavior when distressed. Results highlight directions for future research and suggest that particular aspects of emotion dysregulation may be more or less relevant to BPD.

The borderline diagnosis II: biology, genetics, and clinical course

In Part I of this three-part article, consideration of the core features of BPD psychopathology, of comorbidity with Axis I disorders, and of underlying personality trait structure suggested that the borderline diagnosis might be productively studied from the perspective of dimensions of trait expression, in addition to that of the category itself. In Part II, we review the biology, genetics, and clinical course of borderline personality disorder (BPD), continuing to attend to the utility of a focus on fundamental dimensions of psychopathology. Biological approaches to the study of personality can identify individual differences with both genetic and environmental influences. The aspects of personality disorder that are likely to have biologic correlates are those involving regulation of affects, impulse/action patterns, cognitive organization and anxiety/inhibition. For BPD, key psychobiological domains include impulsive aggression, associated with reduced serotonergic activity in the brain, and affective instability, associated with increased responsivity of cholinergic systems. There may be a strong genetic component for the development of BPD, but it seems clear, at least, that there are strong genetic influences on traits that underlie it, such as neuroticism, impulsivity, anxiousness, affective lability, and insecure attachment. The course of BPD suggests a heterogeneous disorder. Predictors of poor prognosis include history of childhood sexual abuse, early age at first psychiatric contact, chronicity of symptoms, affective instability, aggression, substance abuse, and increased comorbidity. For research purposes, at least, biological, genetic, and prognostic studies all continue to suggest the need to supplement categorical diagnoses of BPD with assessments of key underlying personality trait dimensions and with historical and clinical observations apart from those needed to make the borderline diagnosis itself.

Attachment Studies with Borderline Patients: A Review

&NA; Clinical theorists have suggested that disturbed attachments are central to borderline personality disorder (BPD) psychopathology. This article reviews 13 empirical studies that examine the types of attachment found in individuals with this disorder or with dimensional characteristics of BPD. Comparison among the 13 studies is handicapped by the variety of measures and attachment types that these studies have employed. Nevertheless, every study concludes that there is a strong association between BPD and insecure attachment. The types of attachment found to be most characteristic of BPD subjects are unresolved, preoccupied, and fearful. In each of these attachment types, individuals demonstrate a longing for intimacy and—at the same time—concern about dependency and rejection. The high prevalence and severity of insecure attachments found in these adult samples support the central role of disturbed interpersonal relationships in clinical theories of BPD. This review concludes that these types of insecure attachment may represent phenotypic markers of vulnerability to BPD, suggesting several directions for future research.

Mentalization: ontogeny, assessment, and application in the treatment of borderline personality disorder.

This article aims to review the development of the concept of mentalization, its applications in the understanding and treatment of borderline personality disorder, and the issue of its assessment. While conceptually derivative of theory of mind, Fonagys concept of mentalization concerns more affectively and interpersonally complex understandings of oneself and others, reflecting abilities that enable an individual not only to navigate the social world effectively but also to develop an enriched, stable sense of self. The components of mentalization can be organized around self-/other-oriented, implicit/explicit, and cognitive/affective dimensions. Concepts of mindfulness, psychological mindedness, empathy, and affect consciousness are shown to partially overlap with mentalization within these three dimensions. Mentalization is assessed by the measure of reflective function, a scale to be used adjunctively on semistructured narrative interviews such as the Adult Attachment Interview. Its validity has not been fully tested, and its usage has been hampered by the time and expense it requires. Although the concept of mentalization is a useful heuristic that enables clinicians to adopt a coherent treatment approach, it may be too broad and multifaceted to be operationalized as a marker for specific forms of psychopathology such as borderline personality disorder. Research elucidating the relationship between reflective function, overlapping concepts, and features of borderline psychopathology is needed.

The diagnostic interview for personality disorders: Interrater and test-retest reliability

Abstract The Diagnostic Interview for Personality Disorders (DIPD) is a semistructured interview of 252 questions that encompasses all 11 Axis II disorders described in the DSM-III. Its interrater reliability was assessed using a sample of 43 patients and its test-retest reliability was assessed using a separate sample of 54 patients. Adequate kappas were obtained in both situations for all disorders except schizoid personality disorder, which was never diagnosed. Interrater coefficients ranged from .52 to 1.0, with nine in the excellent range (κ > .75). Test-retest coefficients ranged from .46 to .85, with four in the excellent range. These results compara very favorably to those achieved using the other two Axis II interviews that have appeared in the literature, the Structured Interview for the DSM-III Personality Disorders (SIDP) and the Personality Disorder Examination (PDE).

BPD'S INTERPERSONAL HYPERSENSITIVITY PHENOTYPE: A GENE-ENVIRONMENT- DEVELOPMENTAL MODEL

This paper explores the development of BPD as it might emerge in the childs early interpersonal reactions and how such reactions might evolve into the interpersonal pattern that typifies BPD. It begins to bridge the relevant bodies of clinical literature on the borderlines prototypic interpersonal problems with the concurrently expanding relevant literature on early child development. We will start by considering how a psychobiological disposition to BPD is likely to include a constitutional diathesis for relational reactivity, that is, for hypersensitivity to interpersonal stressors. Data relevant to this dispositions manifestations in adult clinical samples and to its heritability and neurobiology will be reviewed. We then consider how such a psychobiological disposition for interpersonal reactivity might contribute to the development of a disorganized-ambivalent form of attachment, noting especially the likely contributions of both the predisposed child and of parents who are themselves predisposed to maladaptive responses, leading to an escalation of problematic transactions. Evidence concerning both the genetics and the developmental pathways associated with disorganized attachments will be considered. Emerging links between such developmental pathways and adult BPD will be described, in particular the potential appearance by early- to middle-childhood of controlling-caregiving or controlling-punitive interpersonal strategies. Some implications from this gene-environment interactional theory for a better developmental understanding of BPDs etiology are discussed.

Stability of functional impairment in patients with schizotypal, borderline, avoidant, or obsessive–compulsive personality disorder over two years

BACKGROUND A defining feature of personality disorder (PD) is an enduring pattern of inner experience and behavior that is stable over time. Follow-up and follow-along studies have shown considerable diagnostic instability of PDs, however, even over short intervals. What, then, about personality disorder is stable? The purpose of this study was to determine the stability of impairment in psychosocial functioning in patients with four different PDs, in contrast to patients with major depressive disorder (MDD) and no PD, prospectively over a 2-year period. METHOD Six hundred treatment-seeking or treated patients were recruited primarily from clinical services in four metropolitan areas of the Northeastern USA. Patients were assigned to one of five diagnostic groups: schizotypal (STPD) (n=81), borderline (BPD) (n=155), avoidant (AVPD) (n=137), or obsessive-compulsive (OCPD) (n=142) personality disorders or MDD and no PD (n=85), based on the results of semi-structured interview assessments and self-report measures. Impairment in psychosocial functioning was measured using the Longitudinal Interval Follow-up Evaluation (LIFE) at baseline and at three follow-up assessments. RESULTS Significant improvement in psychosocial functioning occurred in only three of seven domains of functioning and was largely the result of improvements in the MDD and no PD group. Patients with BPD or OCPD showed no improvement in functioning overall, but patients with BPD who experienced change in personality psychopathology showed some improvement in functioning. Impairment in social relationships appeared most stable in patients with PDs. CONCLUSION Impairment in functioning, especially social functioning, may be an enduring component of personality disorder.
