The Personality Disorders Institute/Borderline Personality Disorder Research Foundation Randomized Control Trial for Borderline Personality Disorder: reliability of Axis I and II diagnoses.

The Personality Disorder Institute/Borderline Personality Disorder Research Foundation randomized control trial (PDI/BPDRF RCT) is a randomized control trial comparing three treatments for borderline personality disorder (BPD). An important issue for any RCT is diagnostic reliability, demonstration of which is necessary to evaluate claims of a treatment's efficacy for a given population. The present paper examines the interrater reliability of Axis I and II disorders in the context of a high base rate of BPD features for participants referred for inclusion in the RCT. Our results indicate good to excellent levels of interrater reliability for all Axis I and II disorders in this context. Assessors were able to reliably diagnose BPD, exclusionary criteria, and comorbid diagnoses. This data is important for comparing findings and sample composition across different studies using similar sampling strategies, especially as treatments are increasingly being developed and tested for BPD.

Psychotherapy for patients with borderline personality disorder: focusing on the mechanisms of change.

A major development in the field of psychotherapy research is the growing recognition of the need for evidence on the mechanisms of change in psychotherapy. The empirical evidence that psychotherapy has a positive and significant effect must be amplified with data on the mechanisms of action in the various psychotherapies. This special issue is devoted to the articulation of putative mechanisms of change in the psychotherapy of patients with borderline personality disorder by leading researchers in this field.

The mechanisms of change in the treatment of borderline personality disorder with transference focused psychotherapy.

We address how Transference Focused Psychotherapy (TFP) conceptualizes mechanisms in the cause and maintenance of borderline personality disorder (BPD) as well as change mechanisms both within the patient and in terms of specific therapists' interventions that engender patient change. Mechanisms of change at the level of the patient involve the integration of polarized representations of self and others; mechanisms of change at the level of the therapist's interventions include the structured treatment approach and the use of clarification, confrontation, and "transference" interpretations in the here and now of the therapeutic relationship. In addition, we briefly review evidence from our group regarding the following hypothesized mechanisms of change: contract setting, integration of representations, and changes in reflective functioning (RF) and affect regulation.

Change in attachment patterns and reflective function in a randomized control trial of transference-focused psychotherapy for borderline personality disorder.

Changes in attachment organization and reflective function (RF) were assessed as putative mechanisms of change in 1 of 3 year-long psychotherapy treatments for patients with borderline personality disorder (BPD). Ninety patients reliably diagnosed with BPD were randomized to transference-focused psychotherapy (TFP), dialectical behavior therapy, or a modified psychodynamic supportive psychotherapy. Attachment organization was assessed with the Adult Attachment Interview and the RF coding scale. After 12 months of treatment, participants showed a significant increase in the number classified secure with respect to attachment state of mind for TFP but not for the other 2 treatments. Significant changes in narrative coherence and RF were found as a function of treatment, with TFP showing increases in both constructs during treatment. No changes in resolution of loss or trauma were observed across treatments. Findings suggest that 1 year of intensive TFP can increase patients' narrative coherence and RF. Future research should establish the relationship between these 2 constructs and relevant psychopathology, identify treatment components responsible for effecting these changes, and examine the long-term outcome of these changes.

Introduction to the special section on attachment theory and psychotherapy.

In this introduction to the special section on attachment theory and psychotherapy, the editors briefly describe the key points of attachment theory (J. Bowlby, 1969, 1973, 1980) and its relevance to psychotherapy. They then outline their criteria for the selection of papers and briefly describe their emphasis. The aim of this section is to present novel and thought-provoking research that highlights the ways attachment theory principles contribute to understanding psychotherapy practice and outcome. It was the editors' goal to ensure breadth of coverage in terms of specific problems, range of populations, and types of treatments represented and to emphasize attachment-based treatments and outcomes.

Attachment and borderline personality disorder: implications for psychotherapy.

BACKGROUND: Psychopathology researchers and theorists have begun to understand fundamental aspects of borderline personality disorder (BPD) such as unstable and intense interpersonal relationships, feelings of emptiness, bursts of rage, chronic fears of abandonment, intolerance for aloneness, and lack of a stable sense of self as stemming from impairments in the underlying attachment organization. In the present study, we will examine self-reported attachment in a study group of well-characterized patients reliably diagnosed with BPD. SAMPLING AND METHODS: Ninety-nine outpatients reliably diagnosed with BPD using the International Personality Disorders Examination, completed a number of attachment measures including the Relationship Questionnaire, Relationship Style Questionnaire, and Experiences in Close Relationships inventory. RESULTS: Factor analysis revealed six factors that clustered into three groups corresponding to an avoidant attachment pattern, a preoccupied attachment pattern, and a fearfully preoccupied pattern. The preoccupied pattern showed more concern and behavioral reaction to real or imagined abandonments, whereas the avoidant group had higher ratings of inappropriate anger. The fearfully preoccupied group had higher ratings on identity disturbance, although only at the trend level. CONCLUSIONS: The psychometric properties and response characteristics of the ECR items suggest that the scales, keying, and domains are appropriate for assessment of attachment in BPD samples. The scales generally retain their factor structure and show a similar pattern of correlations and inter-relationships. Nevertheless, consistent with a developmental psychopathology model, there are some important differences in factor structure, indicating the need to look at both typical and atypical samples when constructing models of attachment. Further research is needed to delineate the prognostic and prescriptive significance of attachment patterns for treating patients with BPD.

The construct of effortful control: an approach to borderline personality disorder heterogeneity.

BACKGROUND: The present study investigated the heterogeneity of DSM-IV borderline personality disorder (BPD) diagnosis as a function of the construct of effortful control. We hypothesized 3 subgroups of BPD patients based on effortful control, that would also differ in other areas of functioning, such as symptoms, interpersonal relations and personality organization. SAMPLING AND METHODS: Forty-seven clinically referred individuals were reliably diagnosed as meeting DSM-IV criteria for BPD using semistructured interviews. Effortful control, symptomatology, interpersonal functioning and personality organization were assessed using self-report questionnaires. RESULTS: Cluster and profile analyses were performed and identified 3 subgroups. Subgroup 1, with high effortful control, exhibited the fewest problems in symptoms, interpersonal functioning and personality organization. Subgroup 3, with low ratings of effortful control, had the most problems in these areas, and subgroup 2, a group high in some aspects of effortful control but low in others, ranged midway between groups 1 and 3. DISCUSSION: The findings indicate a relationship between attentional mechanisms and the clinical expression of borderline personality pathology. Effortful control is a valuable construct for identifying subgroups of BPD patients, thus helping to understand the heterogeneity in BPD. Limitations of the study include the exclusive use on self-report of effortful control, as well as the small sample size. Future research should further investigate the associations of neurocognition and borderline pathology, as well as different approaches to treatment of the different BPD subgroups.

The implications of attachment theory and research for understanding borderline personality disorder.

Borderline personality disorder (BPD) is a highly prevalent, chronic, and debilitating psychiatric problem characterized by a pattern of chaotic and self-defeating interpersonal relationships, emotional lability, poor impulse control, angry outbursts, frequent suicidality, and self-mutilation. Recently, psychopathology researchers and theorists have begun to understand fundamental aspects of BPD such as unstable, intense interpersonal relationships, feelings of emptiness, bursts of rage, chronic fears of abandonment and intolerance for aloneness, and lack of a stable sense of self as stemming from impairments in the underlying attachment organization. These investigators have noted that the impulsivity, affective lability, and self-damaging actions that are the hallmark of borderline personality occur in an interpersonal context and are often precipitated by real or imagined events in relationships. This article reviews attachment theory and research as a means of providing a developmental psychopathology perspective on BPD. Following a brief review of Bowlby's theory of attachment, and an overview of the evidence with respect to the major claims of attachment theory, I discuss individual differences, the evidence that these differences are rooted in patterns of interaction with caregivers, and how these patterns have important implications for evolving adaptations and development. Following this discussion, I present recent work linking attachment theory and BPD, focusing on the implications for understanding the etiology and treatment of BPD. In conclusion, I address some of the salient issues that point to the direction for future research efforts.

The Personality Disorders Institute/Borderline Personality Disorder Research Foundation randomized control trial for borderline personality disorder: rationale, methods, and patient characteristics.

The Personality Disorder Institute/Borderline Personality Disorder Research Foundation randomized control trial (PDI/BPDRF RCT) is a controlled outcome study for borderline personality disorder (BPD), in which 90 participants were randomized to one of three manualized and monitored, active psychosocial treatment conditions. These treatments are: (a) Transference-Focused Psychotherapy (TFP; Clarkin, Yeomans, & Kernberg, 1999), a treatment for BPD based on object-relational and psychoanalytic principles first applied to BPD by Kernberg (1996), notable for its particular emphasis on interpretation of object relations activated in the ongoing therapeutic relationship; (b) Dialectical Behavior Therapy (DBT; Linehan, 1993), a popular treatment for BPD, with evidence of efficacy (Linehan, Armstrong, Suarez, Allmon, & Heard, 1991) that emphasizes a balance between acceptance and change in its combination of cognitive-behavioral and Zen principles; and (c) supportive psychotherapy (Rockland, 1992), another object-relational and psychoanalytically based treatment for BPD which, in contrast to TFP, eschews transference interpretation and places primary emphasis on development of a collaborative engagement with the patient to foster identity development. Patients received medication, if clearly indicated, according to the treatment algorithm developed by Soloff (2000). This article describes the significance and rationale of the study and the overall design, methods, plan of analysis, and demographic characteristics of the recruited sample of patients.

The relationship between impulsivity, aggression, and impulsive-aggression in borderline personality disorder: an empirical analysis of self-report measures.

Impulsivity has been repeatedly identified as a key construct in BPD; however, its precise definition seems to vary especially regarding the overlap with aggression. The term impulsive-aggression , also generally seen as central to an understanding of BPD, seems to address itself to the interface between the two, but has itself been used inconsistently in the literature, sometimes having reference to a unitary phenotypic dimension, and at other times suggesting some combination of distinct traits. This study examined the relationship between multiple measures of impulsivity, aggression, and impulsive-aggression in a BPD sample ( N = 92) in order to clarify the relationship between these measured constructs in this clinical population. Results show little relationship between measures of aggression and impulsivity in BPD, with measures of impulsive-aggression correlating strongly with measures of aggression only. Implications of the present results for future research and clinical work with BPD are discussed.

An approach to the psychobiology of personality disorders.

Human variability in temperament allows a unique natural experiment where reactivity, self-regulation, and experience combine in complex ways to produce an individual personality. Personality disorders may result from changes in the way past memories filter new information in situations of emotional involvement with others. According to this view, disorders are specific to their initiating circumstances rather than a general difficulty that might extend to classes of information processing remote from triggers for the disorder. A different view suggests a more general deficit in attentional control mechanisms that might extend to a wide range of situations far from those related to the core abnormality. This paper outlines methods for examining these views and presents data from the study of borderline personality disorder, arguing in favor of high negative emotionality being combined with a deficit in an executive attentional control network. Because this attentional network has already been well described in terms of anatomy, the cognitive operations involved, development, chemical modulators, and effects of lesions and candidate genes, these findings may have implications for understanding the disorder and its treatment. We consider these implications in terms of a general approach to the study of personality development and its disorders.

Patient-therapist attachment in the treatment of borderline personality disorder.

The authors report preliminary findings from a longitudinal study on the impact of attachment state of mind and reflective function on therapeutic process and outcome with borderline patients in Transference-Focused Psychotherapy (TFP). TFP is a manualized, psychoanalytically oriented treatment based on an object relations model of understanding patients with severe personality disorders. The attachment theory constructs of internal working models of attachment and mentalization or reflective function provide an important means of both conceptualizing borderline disorders and assessing therapeutic process and change. In the Personality Disorders Institute at New York Presbyterian Hospital-Weill Medical College of Cornell University, the authors have been using the Adult Attachment Interview (AAI) to assess changes in state of mind with respect to attachment and reflective function over the course of 1 year in borderline patients in TFP treatment. As part of the authors' investigations of the impact of patients' attachment status on the therapeutic process, they have adapted the AAI to evaluate states of mind with respect to attachment within the therapeutic relationship through an interview called the Patient-Therapist Adult Attachment Interview (PT-AAI). The AAI is given at 4 months and 1 year, and the PT-AAI is given to patients after 1 year of TFP, and both interviews are scored for attachment classification and reflective function. The authors present preliminary findings on change in both attachment classification and reflective function ratings at 4 months and 1 year for a subsample of 10 patients and therapists. They also present two cases that illustrate how the quality of mentalization or reflective function in the therapeutic dyad may be seen as a bidirectional process in that therapists' and patients' levels of reflective function are mutually and reciprocally influential. In one case, the patient's and therapist's reflective function mirrored each other directly and remained at a low or rudimentary level for the treatment year. Such a pattern of direct imitation does not necessarily promote intrapsychic change. In the second case, the patient moved from a rejecting or bizarre stance toward mentalization on the AAI to some rudimentary consideration of mental states after 1 year of treatment with a therapist who showed a full and nuanced awareness of mental states, but who adjusted his level of mentalization to that of the patient. These findings suggest that optimally the therapist ought to be one step ahead of the patient in the capacity for mentalization.

Attentional mechanisms of borderline personality disorder.

We consider whether disruption of a specific neural circuit related to self-regulation is an underlying biological deficit in borderline personality disorder (BPD). Because patients with BPD exhibit a poor ability to regulate negative affect, we hypothesized that brain mechanisms thought to be involved in such self-regulation would function abnormally even in situations that seem remote from the symptoms exhibited by these patients. To test this idea, we compared the efficiency of attentional networks in BPD patients with controls who were matched to the patients in having very low self-reported effortful control and very high negative emotionality and controls who were average in these two temperamental dimensions. We found that the patients exhibited significantly greater difficulty in their ability to resolve conflict among stimulus dimensions in a purely cognitive task than did average controls but displayed no deficit in overall reaction time, errors, or other attentional networks. The temperamentally matched group did not differ significantly from either group. A significant correlation was found between measures of the ability to control conflict in the reaction-time task and self-reported effortful control.
