Functional fantasies: the regulatory role of grandiose fantasizing in pathological narcissism

Introduction

Pathological narcissism is characterized by maladaptive efforts to maintain a bolstered but fragile sense of self. Clinical theory suggests that grandiose fantasizing may be one form of this self-regulation. However, no empirical research has directly assessed the regulatory function of grandiose fantasizing in narcissism. Here, we examine (1) whether people scoring higher in narcissism choose to engage in grandiose fantasizing to regulate themselves when they are feeling down and (2) whether grandiose fantasizing is a more efficacious self-esteem and affect regulator for people scoring higher in narcissism than it is for those scoring lower in narcissism.

Methods

Adult participants (N = 189) completed a self-report measure of narcissism and were randomized to either a negative mood induction or filler task condition. Then, participants wrote about a future event to make themselves feel better, choosing between a positive affect word or a grandiose word to guide their writing. Throughout the study, participants reported their state positive and negative affect and self-esteem. A secondary sample (N = 128) of adult participants rated the future event writing of the original participants.

Results

Supporting the validity of the study design, grandiose future events significantly differed from positive future events (e.g., they were rated by independent raters as less plausible, more ambitious, more active, and occurring further in the future). Participants scoring higher in narcissism and participants who experienced larger increases in negative affect were more likely to choose to engage in grandiose fantasizing. Grandiose fantasizing was more effective at decreasing negative affect among participants scoring higher in narcissism than those scoring lower in narcissism, whereas positive future thinking was equally effective at decreasing negative affect across levels of narcissism.

Discussion

This study demonstrates that people scoring higher in narcissism are more likely to choose to engage in grandiose fantasizing to make themselves feel better. It further demonstrates that grandiose fantasizing is a more efficacious affect regulator for those scoring higher in narcissism.

Examining the Therapeutic Effect of Ceremonial Ayahuasca on Narcissistic Personality and Antagonistic Externalizing in Adults

Changes in narcissistic traits (e.g., entitlement) following the ceremonial use of ayahuasca were examined across three timepoints (baseline, postretreat, 3-month follow-up) in a sample of 314 adults using self- and informant-report (N = 110) measures. Following ceremonial use of ayahuasca, self-reported changes in narcissism were observed (i.e., decreases in Narcissistic Personality Inventory [NPI] Entitlement-Exploitativeness, increases in NPI Leadership Authority, decreases in a proxy measure of narcissistic personality disorder [NPD]). However, effect size changes were small, results were somewhat mixed across convergent measures, and no significant changes were observed by informants. The present study provides modest and qualified support for adaptive change in narcissistic antagonism up to 3 months following ceremony experiences, suggesting some potential for treatment efficacy. However, meaningful changes in narcissism were not observed. More research would be needed to adequately evaluate the relevance of psychedelic-assisted therapy for narcissistic traits, particularly studies examining individuals with higher antagonism and involving antagonism-focused therapeutic approaches.

Female Narcissism: Assessment, Aetiology, and Behavioural Manifestations

Despite putative gender differences in the expression of narcissism, prominent theories have virtually dismissed the role of females in the development and manifestation of narcissism. The contention that narcissism is a pathology of the self that may partly differ in males and females is further evident in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The DSM-5 reports that up to 75% of those diagnosed with Narcissistic Personality Disorder (NPD) are men. Such figures suggest that the representation of narcissism as codified in the DSM-5 may only be marginally applicable to females, given its prominent focus and nature on capturing grandiose themes which closely resemble commonly masculine norms. The overemphasis on grandiose features extends to the empirical literature which defines narcissism as a normative personality trait and is widely assessed using the Narcissistic Personality Inventory (NPI), on which males obtain significantly higher scores than females. As this review will demonstrate, one limitation frequently occurring in the literature is the attempt to comprehend narcissistic manifestations in females through the lens of what has commonly been defined as narcissism (DSM/NPI). In this review, the literature concerning the diagnostic assessment and conceptualisation of narcissistic personality disorder, aetiological factors, aggression, and partner violence perpetration will be discussed in relation to the importance of gender. This is followed by a review of existing gaps in theory and research, and suggestions for fruitful directions that can aid a richer and more meaningful literature on narcissism inclusive of gender issues.

Narcissism and Quality of Life: The Mediating Role of Relationship Patterns

Pathological narcissism is associated with decreased quality of life, even when accounting for psychiatric comorbidity, but the processes behind this association are unclear. Here, we evaluate whether disturbed relatedness accounts for the negative association between narcissistic pathology and quality of life. Patients in day hospital treatment for personality pathology (N = 218, 70% female; mean age, 37.3 years) completed measures of personality disorder features, quality of life, and global symptoms before beginning treatment. Quality of object relations was assessed through semistructured interviews. Regression-based mediation analyses showed that narcissistic personality traits relate to quality of life through quality of object relations, controlling for other personality disorders and psychiatric distress. These results highlight the importance of problematic relationship patterns for the low quality of life associated with pathological narcissism. Clinicians working with narcissistic individuals should consider psychotherapies that promote mature relatedness and should attend to facilitating the quality of patients' relationships.

Dimensions over categories: a meta-analysis of taxometric research

Taxometric procedures have been used extensively to investigate whether individual differences in personality and psychopathology are latently dimensional or categorical ('taxonic'). We report the first meta-analysis of taxometric research, examining 317 findings drawn from 183 articles that employed an index of the comparative fit of observed data to dimensional and taxonic data simulations. Findings supporting dimensional models outnumbered those supporting taxonic models five to one. There were systematic differences among 17 construct domains in support for the two models, but psychopathology was no more likely to generate taxonic findings than normal variation (i.e. individual differences in personality, response styles, gender, and sexuality). No content domain showed aggregate support for the taxonic model. Six variables - alcohol use disorder, intermittent explosive disorder, problem gambling, autism, suicide risk, and pedophilia - emerged as the most plausible taxon candidates based on a preponderance of independently replicated findings. We also compared the 317 meta-analyzed findings to 185 additional taxometric findings from 96 articles that did not employ the comparative fit index. Studies that used the index were 4.88 times more likely to generate dimensional findings than those that did not after controlling for construct domain, implying that many taxonic findings obtained before the popularization of simulation-based techniques are spurious. The meta-analytic findings support the conclusion that the great majority of psychological differences between people are latently continuous, and that psychopathology is no exception.

Examining the Contribution of Perfectionistic Traits to the Construct Validity of the DSM-5 Alternative Model of Personality Disorder

Scholars of perfectionism have proposed significant modifications to DSM-5's alternative model of personality disorders (AMPD), such that (1) perfectionism be expanded beyond the inclusion of a singular trait-rigid perfectionism-and (2) perfectionistic traits be specified as trait descriptors of personality disorders (PDs) other than obsessive-compulsive PD. In this study, we evaluate these proposals by examining the degree to which (a) perfectionistic traits are already instantiated in Section II and Section III models of personality pathology; and (b) perfectionistic traits meaningfully augment the construct validity of AMPD PDs. We conducted these approaches in a large sample (N =3D 435) from an Iranian undergraduate population that is atypically found in the literature. Results showed that perfectionistic traits are already fairly well instantiated in Section III Criterion B. Perfectionistic traits minimally improved the construct validity of OCPD, but did not meaningfully do so for other PDs. Future investigation into the clinical utility of perfectionistic traits is needed.

Narcissist or narcissistic? Evaluation of the latent structure of narcissistic personality disorder

We investigated the latent structure of narcissistic personality disorder by comparing dimensional, hybrid, and categorical latent variable models, using confirmatory factor analysis (CFA), nonparametric and semiparametric factor analysis, and latent class analysis, respectively. We first explored these models in a clinical sample and then preregistered replication analyses in 4 additional data sets (with national, undergraduate, community, and mixed community/clinical samples) to test whether the best-fitting model would generalize across different data sets with different sample compositions. A 1-factor CFA outperformed categorical models in fit and reliability, suggesting the criteria do not serve to distinguish a narcissist class or subtypes; rather, a narcissistic dimension underlies the narcissistic personality disorder construct. The CFA also outperformed hybrid models, indicating that people fall within the same continuous distribution, rather than composing homogenous groups of relative severity (nonparametric factor analysis) or pulling apart into mixtures of discrete distributions (semiparametric factor analysis) along that spectrum.

Clinical Characteristics of Comorbid Narcissistic Personality Disorder in Patients With Borderline Personality Disorder

This study examines psychopathology and clinical characteristics of patients with borderline personality disorder (BPD) and comorbid narcissistic personality disorder (NPD) from two international randomized controlled trials. From a combined sample of 188 patients with BPD, 25 also fulfilled criteria for a comorbid diagnosis of NPD according to DSM-IV. The BPD patients with comorbid NPD, compared to the BPD patients without comorbid NPD, showed significantly more BPD criteria (M = 7.44 vs. M = 6.55, p < .001), fulfilled more criteria of comorbid histrionic (M = 3.84 vs. M = 1.98, p < .001), paranoid (M = 3.12 vs. M = 2.27, p = .014), and schizotypal (M = 1.64 vs. M = 1.02, p = .018) personality disorders, and were more likely to meet criteria for full histrionic PD diagnosis (44.0% vs. 14.2%, p < .001). The BPD-NPD group also reported significantly fewer psychiatric hospitalizations in the previous year (M = 0.40 vs. M = 0.82, p = .019) and fewer axis I disorders (M = 2.68 vs. M = 3.75, p = .033). No differences could be found in general functioning, self-harming behavior, and suicide attempts.

The Relationship Between Grandiosity, Psychopathy, and Narcissism in an Offender Sample

Clinical accounts suggest grandiosity is an important characteristic of both psychopathy and narcissism. This study examined the relationships between grandiosity and each of these personality disorder syndromes, using a novel index, namely the Grandiosity Index. Seventy-five incarcerated males completed clinical interviews of psychopathy and narcissism and a self-report inventory of narcissism and were rated on interpersonal measures of psychopathy and narcissism. Trained research assistants rated participants on the Grandiosity Index. Analyses provided preliminary evidence of construct validity for the index. Scores on the Grandiosity Index were significantly correlated with scores on both clinical and interpersonal measures of psychopathy and narcissism and with self-reported narcissism. Regressions demonstrated that the Grandiosity Index explained substantial unique variance in psychopathy after controlling for scores on narcissism. This study demonstrates that grandiose features are associated uniquely with clinical ratings of psychopathy, though not significantly more with psychopathy than with narcissism.

Examining sex differences in DSM-IV-TR narcissistic personality disorder symptom expression using Item Response Theory (IRT)

The limited published literature on the subject suggests that there may be differences in how females and males experience narcissistic personality disorder (NPD) symptoms. The aim of this study was to use methods based on item response theory to examine whether, when equating for levels of NPD symptom severity, there are sex differences in the likelihood of reporting DSM-IV-TR NPD symptoms. We conducted these analyses using a large, nationally representative sample from the USA (n=34,653), the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). There were statistically and clinically significant sex differences for 2 out of the 9 DSM-IV-TR NPD symptoms. We found that males were more likely to endorse the item 'lack of empathy' at lower levels of narcissistic personality disorder severity than females. The item 'being envious' was a better indicator of NPD severity in males than in females. There were no clinically significant sex differences on the remaining NPD symptoms. Overall, our findings indicate substantial sex differences in narcissistic personality disorder symptom expression. Although our results may reflect sex-bias in diagnostic criteria, they are consistent with recent views suggesting that narcissistic personality disorder may be underpinned by shared and sex-specific mechanisms.

Clarifying Associations between Psychopathy Facets and Personality Disorders among Offenders

PURPOSE

This study examined bivariate, unique, and multivariate associations between psychopathy facets and other Personality Disorders (PDs).

METHOD

76 incarcerated males were assessed with clinical interviews assessing psychopathy and DSM-5 PDs. Canonical Correlation Analysis (CCA) was used to examine multivariate associations between dimensional scores of psychopathy facets and other PDs.

RESULTS

Preliminary analyses of bivariate and partial associations revealed that much of the covariation between psychopathy and PD traits reflected shared variance among psychopathy facets and among PD traits. After controlling for the shared variance, unique relationships were limited to positive relationships between Narcissistic PD and interpersonal facet and between Paranoid PD and antisocial facet ratings. Canonical Correlation Analysis results yielded two pairs of functions that explained the shared variance between psychopathy and PDs. In the first pair of functions, elevations on the interpersonal and antisocial facets were associated with symptoms of Paranoid, Narcissistic, Histrionic, and Antisocial PDs. In the second pair of functions, high levels of the antisocial facet and low levels of the interpersonal facet were related to Borderline PD.

CONCLUSION

Results suggest that associations between psychopathy and DSM-5 PDs go beyond established links with Antisocial and Narcissistic PDs to include associations with Histrionic, Borderline, and Paranoid PDs.

Narcissistic Personality Disorder and the Structure of Common Mental Disorders

Narcissistic personality disorder (NPD) shows high rates of comorbidity with mood, anxiety, substance use, and other personality disorders. Previous bivariate comorbidity investigations have left NPD multivariate comorbidity patterns poorly understood. Structural psychopathology research suggests that two transdiagnostic factors, internalizing (with distress and fear subfactors) and externalizing, account for comorbidity among common mental disorders. NPD has rarely been evaluated within this framework, with studies producing equivocal results. We investigated how NPD related to other mental disorders in the internalizing-externalizing model using diagnoses from a nationally representative sample (N = 34,653). NPD was best conceptualized as a distress disorder. NPD variance accounted for by transdiagnostic factors was modest, suggesting its variance is largely unique in the context of other common mental disorders. Results clarify NPD multivariate comorbidity, suggest avenues for classification and clinical endeavors, and highlight the need to understand vulnerable and grandiose narcissism subtypes' comorbidity patterns and structural relations.

A latent transition analysis for the assessment of structured diagnostic interviews

Structured diagnostic interviews administered by lay people are commonly used to assess psychiatric disorders, including depression, in large epidemiologic studies. Many interviews utilize "gate" questions, such as screening questions, that allow interviewers to skip entire survey sections for a particular respondent, saving time and reducing respondent fatigue. However, most depression estimates based on these response data are predicated on the assumption that the gate questions function without measurement error or bias. The tenability of this assumption is questionable, and its violation could compromise the reliability and validity of those estimates of depression. In this study, we used a novel application of latent transition analysis to cross-sectional data, accounting for measurement error in different response pathways through the depression module in the World Mental Health Composite International Diagnostic Interview. The analysis included data from 19,734 participants ≥18 years of age in the Comprehensive Psychiatric Epidemiologic Surveys. The latent transition analysis, allowing for measurement error in screening questions and exclusion criteria, produced a higher estimate of the lifetime probability of experiencing depression than did the algorithm based on the Diagnostic and Statistical Manual for Mental Disorders, 4th Edition, Text Revision. This illustration of latent transition analysis applied to item-level data from a complex structured diagnostic tool with gate questions demonstrates the potential utility of an analytic approach that does not automatically assume gate questions function without measurement error. This model could also be used to probe for evidence of measurement bias in the form of differential item function when using structured diagnostic tools in different cultures and languages.

Narcissistic personality disorder: an integrative review of recent empirical data and current definitions

Although concepts of pathological narcissism are as old as psychology and psychiatry itself, only a small number of clinical studies are based on the criteria for narcissistic personality disorder (NPD), as defined in the Diagnostic and Statistical Manuals of Mental Disorders (DSM). As a result, NPD appears to be one of the most controversially discussed nosological entities in psychiatry. Whereas the majority of empirical studies used self or other ratings of NPD criteria to address issues of reliability and validity of the diagnostic category (i.e., internal consistency, factor structure, discriminant validity), only recent research has applied experimental designs to investigate specific features of NPD (e.g., self-esteem, empathy, shame). The aim of this review is to summarize available empirical data on NPD and relate these findings to current definitions of NPD (according to the DSM-5, [1]). In order to do so, this review follows the five steps to establishing diagnostic validity proposed by Robins and Guze [2], i.e., (1) clinical description, (2) laboratory studies, (3) delimitation from other disorders, (4) family studies, and (5) follow up studies. Finally, this review suggests pathways for future research that may assist further nosological evaluation of NPD and contribute to the overall goal, the improvement of treatment for patients.

Grandiose and vulnerable narcissism and the DSM-5 pathological personality trait model

The Diagnostic and Statistical Manual of Personality Disorders (4th ed., American Psychiatric Association, 2000) personality disorders (PDs) that will be included in the DSM-5 will be diagnosed in an entirely different manner; the explicit criterion sets will be replaced with impairments in self and interpersonal functioning and personality traits from a 25-trait dimensional model of personality pathology. From a trait perspective, narcissistic personality disorder (NPD), the focus of this study, is assessed using 2 specific traits: grandiosity and attention seeking. Using a sample collected online from Amazon's Mechanical Turk (MTurk; N=306), we examined the relations among traits from a new measure of DSM-5's trait model--the Personality Inventory for DSM-5 (PID5; Krueger, Derringer, Markon, Watson, & Skodol, in press)--and grandiose and vulnerable narcissism. The 25 traits from PID5 captured a significant portion of the variance in grandiose and vulnerable factors, although the 2 specific facets designated for the assessment of NPD fared substantially better in the assessment of grandiose rather than vulnerable narcissism. These results are discussed in the context of improving the DSM-5's ability to capture both narcissism dimensions.

Categories versus dimensions in personality and psychopathology: a quantitative review of taxometric research

Taxometric research methods were developed by Paul Meehl and colleagues to distinguish between categorical and dimensional models of latent variables. We have conducted a comprehensive review of published taxometric research that included 177 articles, 311 distinct findings and a combined sample of 533 377 participants. Multilevel logistic regression analyses have examined the methodological and substantive variables associated with taxonic (categorical) findings. Although 38.9% of findings were taxonic, these findings were much less frequent in more recent and methodologically stronger studies, and in those reporting comparative fit indices based on simulated comparison data. When these and other possible confounds were statistically controlled, the true prevalence of taxonic findings was estimated at 14%. The domains of normal personality, mood disorders, anxiety disorders, eating disorders, externalizing disorders, and personality disorders (PDs) other than schizotypal yielded little persuasive evidence of taxa. Promising but still not definitive evidence of psychological taxa was confined to the domains of schizotypy, substance use disorders and autism. This review indicates that most latent variables of interest to psychiatrists and personality and clinical psychologists are dimensional, and that many influential taxonic findings of early taxometric research are likely to be spurious.

Factor structure of self-reported clinical disorders and personality disorders: a review of the existing literature and a factor analytical study

OBJECTIVES

The aim of this research is to add to the current understanding of the latent factor structure of personality disorders by performing a review of the existing literature (Study 1) and a factor analytical study on the factor structure and the relationship between self-reported Axis I and Axis II psychopathology (Study 2).

DESIGN

The current research (Study 2) is cross-sectional and multicenter.

RESULTS

We found support for the assumption that the borderline personality disorder is a multidimensional construct. Second, we found evidence for a single-factor structure of the narcissistic, dependent as well as the avoidant personality disorder. Third, we found support for the current Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) distinction between Axis I and Axis II, Axis I psychopathology being explained by the factor neuroticism and Axis II disorders to be further subdivided into the higher order factors of internalizing and externalizing pathology.

CONCLUSIONS

An adaptation to the current DSM-IV borderline personality criteria should be made, while various findings show that the borderline construct is multidimensional. Second, deletion of the dependent and narcissistic personality in the DSM-V might be unjust. Third, Axis I psychopathology can be explained by the factor neuroticism, and Axis II disorders should be further subdivided into the higher order factors of internalizing and externalizing pathology.

Self- and informant-reported perspectives on symptoms of narcissistic personality disorder

Because narcissistic individuals tend to have an inflated view of themselves and their abilities, the reliance on self-reported information in the assessment and diagnosis of narcissistic personality disorder (NPD) is problematic. Hence, the use of informants in the assessment of NPD may be necessary. In the current study we examined self- and informant-reported features of NPD using agreement, frequency, and discrepancy analyses. The results indicated that informants tended to report more NPD features than selves, and that there were either low or nonsignificant levels of self-informant agreement among the 9 NPD diagnostic criteria and its categorical diagnosis. Informants were increasingly more likely to report higher raw scores relative to selves, indicating that the discrepancy between self- and informant reports increases with the NPD scale. Informants also reported NPD features that selves often did not, suggesting that current prevalence estimates of NPD, which use only self-reported information, are most likely underestimates. These results highlight the importance of gathering informant-reported data in addition to self-reported data when assessing NPD. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

Debates on the narcissism conundrum: trait, domain, dimension, type, or disorder?

The clinical implications of the term narcissism are a matter of continuous debate. This article critically examines pertinent literature of the last 12 years using a set of validators and attempting to identify narcissism as a trait, a domain, a dimension, or a personality disorder/type. Narcissistic personality disorder (NPD)-specific literature (particularly in epidemiological, developmental, and laboratory-testing areas) is scarce when compared with other personality disorders. A tendency to ideologically dominated clinical reports is observed with individual cases or small samples of nonclinical populations. Clinical descriptions of the condition vary within a wide range of descriptors, superficial or ambiguous conceptualizations, different subtypes, and inconclusive meta-analytical findings. Comorbidity with many Axes I and II conditions and the presence of narcissistic behavioral and emotional manifestations in other DSM conditions were frequent findings. The reintroduction of NPD in the personality disorders DSM-5 proposal seems to be related to nonclinical or heuristic considerations. It is concluded that NPD as such shows nosological inconsistency and that its consideration as a trait domain with needed further research would be strongly beneficial to the field.

Validity aspects of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, narcissistic personality disorder construct

BACKGROUND

The Diagnostic and Statistical Manual of Mental Disorders (DSM), Fourth Edition, narcissistic personality disorder (NPD) construct has been criticized for being too narrowly defined, for example, by focusing on overt grandiosity at the expense of exhibitionism and narcissistic vulnerability and thus covering only parts of the domain of narcissism. The purpose of this study was to elucidate several validity aspects of the NPD construct.

METHODS

The material consisted of data from 2277 patients (80% of whom had a personality disorder [PD]) who were admitted to units connected to The Norwegian Network of Psychotherapeutic Day Hospitals. The Axis II diagnoses were assessed by Structured Clinical Interview for DSM, Fourth Edition, Axis II Personality Disorders.

RESULTS

The frequency of NPD was very low (0.8%). Male patients were overrepresented both on a diagnostic level and on criteria levels. The NPD category was positively associated with other cluster B disorders and negatively associated with avoidant PD. The criteria "demands excessive admiration" and "fantasies of unlimited success" correlated almost as highly with the histrionic PD category and loaded primarily on a histrionic factor. The dominant NPD factor also included the antisocial criterion of "showing no regret having injured others." The major part of the patients' personality pathology could be attributed to other PD criteria.

CONCLUSIONS

The results challenge the notion of NPD as a distinct diagnostic category. Rather, narcissism should be conceived as personality dimensions pertinent to the whole range of PDs. The results support the views put forward by Russ et al (Refining the construct of narcissistic personality disorder: diagnostic criteria and subtypes. Am J Psychiatry 2008;11:1473-1481) that what clinicians conceive as narcissism consists of several subtypes (dimensions). Our data support the existence of a grandiose/malignant type and an exhibitionistic type. Unfortunately, there was no measure of hypersensitivity. The proposal to delete NPD as a prototype category in the DSM, Fifth Edition, seems well justified. However, the proposed trait domain of antagonism in the DSM, Fifth Edition, seems to account better for the grandiose/malignant dimension than the exhibitionistic/histrionic dimension.

Lack of empathy in patients with narcissistic personality disorder

The study's objective was to empirically assess cognitive and emotional empathy in patients with narcissistic personality disorder (NPD). To date, "lack of empathy" is a core feature of NPD solely based on clinical observation. The study's method was that forty-seven patients with NPD, 53 healthy controls, and 27 clinical controls with borderline personality disorder (BPD) were included in the study. Emotional and cognitive empathy were assessed with traditional questionnaire measures, the newly developed Multifaceted Empathy Test (MET), and the Movie for the Assessment of Social Cognition (MASC). The study's results were that individuals with NPD displayed significant impairments in emotional empathy on the MET. Furthermore, relative to BPD patients and healthy controls, NPD patients did not show deficits in cognitive empathy on the MET or MASC. Crucially, this empathic profile of NPD is not captured by the Structured Clinical Interview for DSM-IV for Axis II Disorders (SCID-II). The study's conclusions were that while NPD involves deficits in emotional empathy, cognitive empathy seems grossly unaffected.

Narcissistic personality disorder in DSM-V--in support of retaining a significant diagnosis

Narcissistic personality disorder, NPD, has been excluded as a diagnostic category and independent personality disorder type in the Personality and Personality Disorder Work Group's recent proposal for DSM-5 Personality and Personality Disorders. The aim of this paper is to present supporting evidence in favor of keeping NPD as a personality type with a set of separate diagnostic criteria in DSM-5. These include: the prevalence rate, extensive clinical and empirical reports and facts, its psychiatric, social and societal significance especially when associated to functional vocational and interpersonal impairment, social and moral adaptation, and acute suicidality. Proposals for a clinically relevant and empirically based definition of narcissism, a description of the narcissistic personality disorder type, and a set of diagnostic criteria for NPD are outlined.

Personality disorder types proposed for DSM-5

The Personality and Personality Disorders Work Group has proposed five specific personality disorder (PD) types for DSM-5, to be rated on a dimension of fit: antisocial/psychopathic, avoidant, borderline, obsessive-compulsive, and schizotypal. Each type is identified by core impairments in personality functioning, pathological personality traits, and common symptomatic behaviors. The other DSM-IV-TR PDs and the large residual category of personality disorder not otherwise specified (PDNOS) will be represented solely by the core impairments combined with specification by individuals' unique sets of personality traits. This proposal has three main features: (1) a reduction in the number of specified types from 10 to 5; (2) description of the types in a narrative format that combines typical deficits in self and interpersonal functioning and particular configurations of traits and behaviors; and (3) a dimensional rating of the degree to which a patient matches each type. An explanation of these modifications in approach to diagnosing PD types and their justifications--including excessive co-morbidity among DSM-IV-TR PDs, limited validity for some existing types, lack of specificity in the definition of PD, instability of current PD criteria sets, and arbitrary diagnostic thresholds--are the subjects of this review.

Measurement non-invariance of DSM-IV narcissistic personality disorder criteria across age and sex in a population-based sample of Norwegian twins

We investigated measurement non-invariance of DSM-IV narcissistic personality disorder (NPD) criteria across age and sex in a population-based cohort sample of 2794 Norwegian twins. Age had a statistically significant effect on the factor mean for NPD. Sex had a statistically significant effect on the factor mean and variance. Controlling for these factor level effects, item-level analysis indicated that the criteria were functioning differently across age and sex. After correcting for measurement differences at the item level, the latent factor mean effect for age was no longer statistically significant. The mean difference for sex remained statistically significant after correcting for item threshold effects. The results indicate that DSM-IV NPD criteria perform differently in males and females and across age. Differences in diagnostic rates across groups may not be valid without correcting for measurement non-invariance.

Pathological narcissism and narcissistic personality disorder

We review the literature on pathological narcissism and narcissistic personality disorder (NPD) and describe a significant criterion problem related to four inconsistencies in phenotypic descriptions and taxonomic models across clinical theory, research, and practice; psychiatric diagnosis; and social/personality psychology. This impedes scientific synthesis, weakens narcissism's nomological net, and contributes to a discrepancy between low prevalence rates of NPD and higher rates of practitioner-diagnosed pathological narcissism, along with an enormous clinical literature on narcissistic disturbances. Criterion issues must be resolved, including clarification of the nature of normal and pathological narcissism, incorporation of the two broad phenotypic themes of narcissistic grandiosity and narcissistic vulnerability into revised diagnostic criteria and assessment instruments, elimination of references to overt and covert narcissism that reify these modes of expression as distinct narcissistic types, and determination of the appropriate structure for pathological narcissism. Implications for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders and the science of personality disorders are presented.

Narcissistic personality disorder: a current review

The diagnosis of narcissistic personality disorder in the DSM-IV has been criticized foremost for its limitations in capturing the range and complexity of narcissistic pathology. The attention to the narcissistic individual's external, symptomatic, or social interpersonal patterns--at the expense of his or her internal complexity and individual suffering--has also added to the diagnosis' low clinical utility and limited guidance for treatment. Recent studies and reviews have pointed to the need for change in the diagnostic approach to and formulation of narcissism. This review focuses specifically on studies of features that add to the identification, understanding, and treatment of patients with pathological narcissistic functioning and narcissistic personality disorder. They have been integrated into a regulatory model that includes the functions and fluctuations of internal control, self-esteem, perfectionism with accompanying self-criticism, shame, and empathic ability and functioning.

What makes narcissists bloom? A framework for research on the etiology and development of narcissism

Narcissism is a dynamic form of personality characterized by a pervasive sense of grandiosity and self-importance, and by a need to obtain continuous self-validation from others. Very little is known about its etiology and development. What factors (e.g., temperament, parenting experiences) and processes (e.g., transactions between these factors over time) cause some children to become more narcissistic than others? When does narcissism first emerge, and how does narcissism develop over time? This article describes a framework for research on the etiology and development of narcissism, and recommends ten research priorities. This research should yield fundamental knowledge and should inform intervention efforts to minimize the negative impact narcissistic individuals have on themselves and on others.

Assessment procedures for narcissistic personality disorder: a comparison of the personality diagnostic questionnaire-4 and best-estimate clinical judgments

This study examined the degree of correspondence between two assessments for narcissistic personality disorder (NPD) in a mixed clinical and community sample--one using a self-report measure (Personality Diagnostic Questionnaire-4) and the other using clinical judgments derived from an assessment based on the longitudinal, expert, all data (LEAD) methodology. NPD scores demonstrated moderate convergence for the total scores but weak convergence for the individual criteria. The authors also examined the correlates created by each set of NPD scores using Cloninger's Temperament and Character Inventory (TCI). The NPD scores demonstrated areas of convergence (e.g., Cooperativeness, Self-directedness) and divergence (i.e., Harm Avoidance, Novelty Seeking) with these personality scores. These divergences may be due to the wording of certain items on the Personality Diagnostic Questionnaire-4 NPD scale, which may require rewriting if it is to provide an assessment that is more highly convergent with the Diagnostic and Statistical Manual of Mental Disorders NPD construct.

A brief taxometrics primer

Taxometric procedures provide an empirical means of determining which psychiatric disorders are typologically distinct from normal behavioral functioning. Although most disorders reflect extremes along continuously distributed behavioral traits, identifying those that are discrete has important implications for accurate diagnosis, effective treatment, early identification of risk, and improved understanding of etiology. This article provides (a) brief descriptions of the conceptual bases of several taxometric procedures, (b) example analyses using simulated data, and (c) strategies for avoiding common pitfalls that are often observed in taxometrics research. To date, most taxometrics studies have appeared in the adult psychopathology literature. It is hoped that this primer will encourage interested readers to extend taxometrics research to child and adolescent populations.

An examination of the factor structure of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, narcissistic personality disorder criteria: one or two factors?

A growing body of research has suggested that narcissistic personality disorder (NPD) contains 2 factors or types: overt/grandiose and covert/vulnerable. A recent factor analysis of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), NPD symptoms supported a similar 2-factor model. The present research tested this proposed 2-factor solution against a 1-factor solution (N = 289; 72% patients) using both confirmatory factor analysis and an examination of associations between the resultant factors and theoretically relevant criteria (other personality disorders; depression, anxiety). The results of the confirmatory factor analysis supported a 1-factor solution. Likewise, the 2 factors each yielded a similar pattern of correlations with relevant criteria. Together, these results argue against a 2-factor structure for the current DSM-IV NPD symptoms. Given the broader research literature suggesting a 2-factor structure of narcissism, strategies for assessing both overt/grandiose and covert/vulnerable forms of narcissism in DSM-V are discussed.

Narcissism at the crossroads: phenotypic description of pathological narcissism across clinical theory, social/personality psychology, and psychiatric diagnosis

This review documents two themes of emphasis found in phenotypic descriptions of pathological narcissism across clinical theory, social/personality psychology, and psychiatric diagnosis. Clinical theories of narcissism spanning 35 years consistently describe variations in the expression of pathological narcissism that emphasize either grandiosity or vulnerable affects and self-states. Recent research in social/personality psychology examining the structure of narcissistic personality traits consistently finds two broad factors representing Grandiosity-Exhibitionism and Vulnerability-Sensitivity-Depletion respectively. However, the majority of psychiatric criteria for narcissistic personality disorder (NPD) in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994) emphasize expressions of grandiosity. By placing most of the diagnostic emphasis on overt grandiosity, DSM NPD has been limited by poor discriminant validity, modest levels of temporal stability, and the lowest prevalence rate on Axis II. Despite converging support for two phenotypic themes associated with pathological narcissism, psychiatric diagnosis and social/personality psychology research often focus only on grandiosity in the assessment of narcissism. In contrast, clinical theory struggles with a proliferation of labels describing these broad phenotypic variations. We conclude that the construct of pathological narcissism is at a crossroads and provide recommendations for diagnostic assessment, clinical conceptualization, and future research that could lead to a more integrated understanding of narcissistic personality and narcissistic personality pathology.

Assessment and diagnosis of personality disorder: perennial issues and an emerging reconceptualization

This chapter reviews recent (2000-2005) personality disorder (PD) research, focusing on three major domains: assessment, comorbidity, and stability. (a) Substantial evidence has accrued favoring dimensional over categorical conceptualization of PD, and the five-factor model of personality is prominent as an integrating framework. Future directions include assessing dysfunction separately from traits and learning to utilize collateral information. (b) To address the pervasiveness and extent of comorbidity, researchers have begun to move beyond studying overlapping pairs or small sets of disorders and are developing broader, more integrated common-factor models that cross the Axis I-Axis II boundary. (c) Studies of PD stability have converged on the finding that PD features include both more acute, dysfunctional behaviors that resolve in relatively short periods, and maladaptive temperamental traits that are relatively more stable-similar to normal-range personality traits-with increasing stability until after 50 years of age. A new model for assessing PD-and perhaps all psychopathology-emerges from integrating these interrelated reconceptualizations.

Evidence for a single latent class of Diagnostic and Statistical Manual of Mental Disorders borderline personality pathology

Borderline personality disorder (BPD) has been described as clinically heterogeneous, with numerous subtypes of the disorder posited. The present study investigated this potential heterogeneity by conducting both confirmatory factor analysis and latent class analysis of consensus ratings of Diagnostic and Statistical Manual of Mental Disorders (DSM) Revised Third Edition BPD criteria in a mixed clinical and nonclinical sample (n = 411). Confirmatory factor analysis results suggested that a single factor fit the data most parsimoniously. Latent class analysis results supported 2 latent classes: those with a high likelihood of BPD symptoms (n = 171) and those with a low likelihood (n = 240). The borderline latent class was more inclusive than diagnoses made based on DSM-III-R thresholds and improved prediction of symptom severity and interpersonal dysfunction, suggesting the clinical importance of 3 or more BPD criteria. Future research on subtypes of BPD may benefit by focusing on variables that supplement the DSM criteria.

Narcissistic personality disorder: relations with distress and functional impairment

This study examined the construct validity of narcissistic personality disorder (NPD) by examining the relations between NPD and measures of psychologic distress and functional impairment both concurrently and prospectively across 2 samples. In particular, the goal was to address whether NPD typically "meets" criterion C of the DSM-IV definition of Personality Disorder, which requires that the symptoms lead to clinically significant distress or impairment in functioning. Sample 1 (n = 152) was composed of individuals receiving psychiatric treatment, whereas sample 2 (n = 151) was composed of both psychiatric patients (46%) and individuals from the community. Narcissistic personality disorder was linked to ratings of depression, anxiety, and several measures of impairment both concurrently and at 6-month follow-up. However, the relations between NPD and psychologic distress were (a) small, especially in concurrent measurements, and (b) largely mediated by impaired functioning. Narcissistic personality disorder was most strongly related to causing pain and suffering to others, and this relationship was significant even when other Cluster B personality disorders were controlled. These findings suggest that NPD is a maladaptive personality style which primarily causes dysfunction and distress in interpersonal domains. The behavior of narcissistic individuals ultimately leads to problems and distress for the narcissistic individuals and for those with whom they interact.
