Initial Construction and Validation of the Pathological Narcissism Inventory

The construct of narcissism is inconsistently defined across clinical theory, social-personality psychology, and psychiatric diagnosis. Two problems were identified that impede integration of research and clinical findings regarding narcissistic personality pathology: (a) ambiguity regarding the assessment of pathological narcissism vs. normal narcissism and (b) insufficient scope of existing narcissism measures. Four studies are presented documenting the initial derivation and validation of the Pathological Narcissism Inventory (PNI). The PNI is a 52-item self-report measure assessing 7 dimensions of pathological narcissism spanning problems with narcissistic grandiosity (Entitlement Rage, Exploitativeness, Grandiose Fantasy, Self-sacrificing Self-enhancement) and narcissistic vulnerability (Contingent Self-esteem, Hiding the Self, Devaluing). The PNI structure was validated via confirmatory factor analysis. The PNI correlated negatively with self-esteem and empathy, and positively with shame, interpersonal distress, aggression, and borderline personality organization. Grandiose PNI scales were associated with vindictive, domineering, intrusive, and overly-nurturant interpersonal problems, and vulnerable PNI scales were associated with cold, socially avoidant, and exploitable interpersonal problems. In a small clinical sample, PNI scales exhibited significant associations with parasuicidal behavior, suicide attempts, homicidal ideation, and several aspects of psychotherapy utilization.

Interpersonal Pathoplasticity in the Course of Major Depression

OBJECTIVE The identification of reliable predictors of course in major depressive disorder (MDD) has been difficult. Evidence suggests that the co-occurrence of personality pathology is associated with longer time to MDD remission. Interpersonal pathoplasticity, the mutually influencing nonetiological relationship between psychopathology and interpersonal traits, offers an avenue for examining specific personality vulnerabilities that may be associated with depressive course. METHOD This study examined 312 participants with and without a co-occurring personality disorder diagnosis who met criteria for a current MDD episode at baseline and who were followed for 10 years in the Collaborative Longitudinal Personality Disorders Study. RESULTS Latent profile analysis (LPA) identified 6 interpersonal groups (extraverted, dominant, arrogant, cold, submissive, and unassuming), and circular statistical profile analysis confirmed group interpersonal distinctiveness. No significant differences between groups were found in comorbid Axis I disorders or baseline MDD severity. Chronicity and functioning analyses found significantly greater chronicity and poorer functioning in individuals with a submissive interpersonal style over 10 years. CONCLUSIONS These findings support the relevance of interpersonal pathoplasticity in depressive course and that this heterogeneity has clinical significance. This study is the first to use LPA and circular profiles to examine interpersonal heterogeneity within a diagnostic group. The implications of these findings for therapeutic intervention, interpersonal functioning, and psychopathological course are discussed.

Interpersonal Subtypes in Social Phobia: Diagnostic and Treatment Implications

Interpersonal assessment may provide a clinically useful way to identify subtypes of social phobia. In this study, we examined evidence for interpersonal subtypes in a sample of 77 socially phobic outpatients. A cluster analysis based on the dimensions of dominance and love on the Inventory of Interpersonal Problems–Circumplex Scales (Alden, Wiggins, & Pincus, 1990) found 2 interpersonal subtypes of socially phobic patients. These subtypes did not differ on pretreatment global symptom severity as measured by the Brief Symptom Inventory (Derogatis, 1993) or diagnostic comorbidity but did exhibit differential responses to outpatient psychotherapy. Overall, friendly-submissive social phobia patients had significantly lower scores on measures of social anxiety and significantly higher scores on measures of well-being and satisfaction at posttreatment than cold-submissive social phobia patients. We discuss the results in terms of interpersonal theory and the clinical relevance of assessment of interpersonal functioning prior to beginning psychotherapy with socially phobic patients.

The impact of pathological narcissism on psychotherapy utilization, initial symptom severity, and early-treatment symptom change: a naturalistic investigation.

The impact of pathological narcissism on psychotherapy has seldom been investigated empirically, despite extensive clinical theory proposing that highly narcissistic individuals should be reluctant to engage in treatment and derive smaller benefits from therapy. In this study, we investigate the relationship between scores on the Pathological Narcissism Inventory (PNI; Pincus et al., 2009), which assesses both narcissistic grandiosity and narcissistic vulnerability, and clinical variables in a sample of outpatients (N = 60) at a community mental health center. Results indicated that grandiosity, but not vulnerability, was negatively related to the use of adjunctive services and positively predicted client-initiated termination of psychotherapy. In addition, grandiosity and vulnerability were related to initial levels of different symptoms in multilevel models using a subsample (n = 41) but not generally related to the linear rate of symptom change in early psychotherapy. The results highlight the clinical utility of assessing pathological narcissism in a real-world psychotherapeutic context.

Attachment and Mentalization in Female Patients With Comorbid Narcissistic and Borderline Personality Disorder

We investigated attachment representations and the capacity for mentalization in a sample of adult female borderline patients with and without comorbid narcissistic personality disorder (NPD). Participants were 22 borderline patients diagnosed with comorbid NPD (NPD/BPD) and 129 BPD patients without NPD (BPD) from 2 randomized clinical trials. Attachment and mentalization were assessed on the Adult Attachment Interview (AAI; George, Kaplan, & Main, 1996). Results showed that as expected, compared with the BPD group, the NPD/BPD group was significantly more likely to be categorized as either dismissing or cannot classify on the AAI, whereas the BPD group was more likely to be classified as either preoccupied or unresolved for loss and abuse than was the NPD/BPD group. Both groups of patients scored low on mentalizing, and there were no significant differences between the groups, indicating that both NPD/BPD and BPD individuals showed deficits in this capacity. The clinical implications of the group differences in AAI classification are discussed with a focus on how understanding the attachment representations of NPD/BPD patients helps to illuminate their complex, contradictory mental states.

The relationship between effortful control, current psychopathology and interpersonal difficulties in adulthood.

This study examined whether the relationship between low effortful control (EC), general psychopathology and interpersonal maladjustment previously reported among children extends to adulthood. Two hundred and forty undergraduate students were assessed using the EC scale of the Adult Temperament Questionnaire, the General Severity Index of the Brief Symptom Inventory (BSI-GSI) and the interpersonal distress index of the Inventory of Interpersonal Problems-Short Circumplex (IIP-distress). Both the BSI-GSI and the IIP-distress scores were related to low levels of EC. Furthermore, interpersonal distress mediated the association between low EC and greater psychopathology severity. These results suggest that deficits in regulatory temperament among adults may be associated with experiencing greater psychopathology distress, and that this relationship may be explained by an impairment in interpersonal adjustment. Such preliminary findings may constitute a useful starting point for investigating this hypothesis among clinical populations.

Assessing interpersonal profiles associated with varying levels of effortful control.

Research has linked individual differences in effortful control (EC) with variations in interpersonal functioning in children and adolescents. Using the Inventory of Interpersonal Problems–Short Circumplex (Hopwood, Pincus, DeMoor, & Koonce, 2008), this study investigated interpersonal problem profiles associated with EC in 763 nonclinical young adults. We found that individuals with low EC reported intrusive interpersonal problems and high levels of interpersonal distress, whereas individuals with high EC reported cold interpersonal problems but low levels of interpersonal distress. Results suggest that EC might play an important role in shaping interpersonal functioning.

Interpersonal Functioning in Obsessive–Compulsive Personality Disorder

The core symptoms of obsessive–compulsive personality disorder (OCPD) often lead to interpersonal difficulties. However, little research has explored interpersonal functioning in OCPD. This study examined interpersonal problems, interpersonal sensitivities, empathy, and systemizing, the drive to analyze and derive underlying rules for systems, in a sample of 25 OCPD individuals, 25 individuals with comorbid OCPD and obsessive–compulsive disorder (OCD), and 25 healthy controls. We found that OCPD individuals reported hostile-dominant interpersonal problems and sensitivities with warm-dominant behavior by others, whereas OCPD+OCD individuals reported submissive interpersonal problems and sensitivities with warm-submissive behavior by others. Individuals with OCPD, with and without OCD, reported less empathic perspective taking relative to healthy controls. Finally, we found that OCPD males reported a higher drive to analyze and derive rules for systems than OCPD females. Overall, results suggest that there are interpersonal deficits associated with OCPD and the clinical implications of these deficits are discussed.

Change in Attachment and Reflective Function in Borderline Patients with and without Comorbid Narcissistic Personality Disorder in Transference Focused Psychotherapy

Abstract Research has consistently found high rates of comorbidity between narcissistic personality disorder (NPD) and borderline personality disorder (BPD). Patients with this complex clinical presentation often present formidable challenges for clinicians, such as intense devaluation, entitlement, and exploitation. However, there is a significant gap in the literature in identifying the clinical characteristics of these NPD/BPD patients. In this article, we present recent research describing patients with comorbid NPD/BPD, as compared with patients with BPD without NPD (BPD), from two randomized clinical trials for the treatment of borderline personality disorder, with a particular emphasis on attachment status and mentalization. We anchor our discussion of these patients in object relations and attachment theory, and we describe our treatment approach, transference focused psychotherapy (TFP). We conclude by using case material to illustrate our research findings, highlighting the significant differences between patients with NPD/BPD and BPD/non-NPD in terms of their attachment classification.

Mental state identification, borderline pathology, and the neglected role of childhood trauma.

Research evaluating mental state identification in individuals with borderline pathology has yielded inconsistent results; contradictory findings were hypothesized to be driven by moderating effects of childhood trauma. Participants were 105 ethnically diverse men and women who exhibited a range of borderline pathology measured by Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria for borderline personality disorder. Mental state identification accuracy was measured using the Reading the Mind in the Eyes Test (RMET). Greater childhood abuse, but not childhood neglect, was associated with enhanced mental state identification accuracy on negative stimuli, when controlling for dissociation (ps < .05); these findings could not be explained by reaction time (RT) or response bias. Childhood abuse and childhood neglect were not related to mental state identification accuracy on neutral or positive stimuli, and they did not moderate the relationship between borderline pathology and mental state identification accuracy on negative, neutral, or positive stimuli. Borderline pathology was not independently related to mental state identification accuracy on negative, neutral, or positive stimuli. Greater childhood neglect, but not childhood abuse, was related to slower RTs on negative, neutral, and positive stimuli (ps < .05). Results underline the importance of separately assessing childhood abuse and childhood neglect and of controlling for dissociation, and they suggest borderline pathology may not universally hinder complex mental state identification.
