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.

BACKGROUND Cumulative adversity and stress are associated with risk of psychiatric disorders. While basic science studies show repeated and chronic stress effects on prefrontal and limbic neurons, human studies examining cumulative stress and effects on brain morphology are rare. Thus, we assessed whether cumulative adversity is associated with differences in gray matter volume, particularly in regions regulating emotion, self-control, and top-down processing in a community sample. METHODS One hundred three healthy community participants, aged 18 to 48 and 68% male, completed interview assessment of cumulative adversity and a structural magnetic resonance imaging protocol. Whole-brain voxel-based-morphometry analysis was performed adjusting for age, gender, and total intracranial volume. RESULTS Cumulative adversity was associated with smaller volume in medial prefrontal cortex (PFC), insular cortex, and subgenual anterior cingulate regions (familywise error corrected, p < .001). Recent stressful life events were associated with smaller volume in two clusters: the medial PFC and the right insula. Life trauma was associated with smaller volume in the medial PFC, anterior cingulate, and subgenual regions. The interaction of greater subjective chronic stress and greater cumulative life events was associated with smaller volume in the orbitofrontal cortex, insula, and anterior and subgenual cingulate regions. CONCLUSIONS Current results demonstrate that increasing cumulative exposure to adverse life events is associated with smaller gray matter volume in key prefrontal and limbic regions involved in stress, emotion and reward regulation, and impulse control. These differences found in community participants may serve to mediate vulnerability to depression, addiction, and other stress-related psychopathology.

Despite a general consensus that dimensional models are superior to the categorical representations of personality disorders in DSM-IV, proposals for how to depict personality pathology dimensions vary substantially. One important question involves how to separate clinical severity from the style of expression through which personality pathology manifests. This study empirically distinguished stylistic elements of personality pathology symptoms from the overall severity of personality disorder in a large, longitudinally assessed clinical sample (N = 605). Data suggest that generalized severity is the most important single predictor of current and prospective dysfunction, but that stylistic elements also indicate specific areas of difficulty. Normative personality traits tend to relate to the general propensity for personality pathology, but not stylistic elements of personality disorders. Overall, findings support a three-stage diagnostic strategy involving a global rating of personality disorder severity, ratings of parsimonious and discriminant valid stylistic elements of personality disorder, and ratings of normative personality traits.

OBJECTIVE To examine prospectively the course of major depressive disorder (MDD) and to test for the moderating effects of personality disorder (PD) comorbidity on relapse after remission from an episode of MDD. METHOD Participants were 303 patients (196 women and 107 men) with current DSM-IV-diagnosed MDD at baseline enrollment in the Collaborative Longitudinal Personality Disorders Study. Major depressive disorder and Axis I psychiatric disorders were assessed with the Structured Clinical Interview for DSM-IV, and Axis II PDs were assessed with the Diagnostic Interview for DSM-IV Personality Disorders. The course of MDD was assessed with the Longitudinal Interval Follow-up Evaluation at 6 and 12 months and then yearly through 6 years. Survival analyses were used to analyze time to remission and time to relapse. The study was conducted from July 1996 to June 2005. RESULTS Of 303 patients, 260 (86%) remitted from MDD; life table survival analyses revealed that patients with MDD who had PDs at baseline had significantly longer time to remission from MDD than patients without PDs. Among the 260 patients whose MDD remitted, 183 (70%) relapsed. Patients with MDD with PDs-specifically those with borderline and obsessive-compulsive PDs-at baseline had significantly shorter time to relapse than patients with MDD without PDs. Cox proportional hazards regression analyses revealed that the presence of PDs at baseline (hazard ratio = 1.5) and recurrent-type MDD (hazard ratio = 2.2), but not sex (hazard ratio = 1.03) or dysthymic disorder (hazard ratio = 0.97), significantly predicted time to relapse. CONCLUSIONS Personality disorders at baseline were robust predictors prospectively of accelerated relapse after remission from an episode of MDD. Personality disorders at baseline significantly moderated eventual time to relapse in MDD among patients who remitted from an episode of MDD, even when controlling for other potential negative prognostic predictors.

BACKGROUND Several conceptual models have been considered for the assessment of personality pathology in DSM-5. This study sought to extend our previous findings to compare the long-term predictive validity of three such models: the five-factor model (FFM), the schedule for nonadaptive and adaptive personality (SNAP), and DSM-IV personality disorders (PDs). METHOD An inception cohort from the Collaborative Longitudinal Personality Disorder Study (CLPS) was followed for 10 years. Baseline data were used to predict long-term outcomes, including functioning, Axis I psychopathology, and medication use. RESULTS Each model was significantly valid, predicting a host of important clinical outcomes. Lower-order elements of the FFM system were not more valid than higher-order factors, and DSM-IV diagnostic categories were less valid than dimensional symptom counts. Approaches that integrate normative traits and personality pathology proved to be most predictive, as the SNAP, a system that integrates normal and pathological traits, generally showed the largest validity coefficients overall, and the DSM-IV PD syndromes and FFM traits tended to provide substantial incremental information relative to one another. CONCLUSIONS DSM-5 PD assessment should involve an integration of personality traits with characteristic features of PDs.

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.

BACKGROUND This study prospectively examined the natural clinical course of six anxiety disorders over 7 years of follow-up in individuals with personality disorders (PDs) and/or major depressive disorder. Rates of remission, relapse, new episode onset and chronicity of anxiety disorders were examined for specific associations with PDs. METHOD Participants were 499 patients with anxiety disorders in the Collaborative Longitudinal Personality Disorders Study, who were assessed with structured interviews for psychiatric disorders at yearly intervals throughout 7 years of follow-up. These data were used to determine probabilities of changes in disorder status for social phobia (SP), generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), panic disorder and panic disorder with agoraphobia. RESULTS Estimated remission rates for anxiety disorders in this study group ranged from 73% to 94%. For those patients who remitted from an anxiety disorder, relapse rates ranged from 34% to 67%. Rates for new episode onsets of anxiety disorders ranged from 3% to 17%. Specific PDs demonstrated associations with remission, relapse, new episode onsets and chronicity of anxiety disorders. Associations were identified between schizotypal PD with course of SP, PTSD and GAD; avoidant PD with course of SP and OCD; obsessive-compulsive PD with course of GAD, OCD, and agoraphobia; and borderline PD with course of OCD, GAD and panic with agoraphobia. CONCLUSIONS Findings suggest that specific PD diagnoses have negative prognostic significance for the course of anxiety disorders underscoring the importance of assessing and considering PD diagnoses in patients with anxiety disorders.

Examining the interpersonal model of binge eating and loss of control over eating in women

Emily B. Ansell; Carlos M. Grilo; Marney A. White

OBJECTIVE This study examined the interpersonal model of binge eating (Wilfley et al., Interpersonal Psychotherapy for Group, New York: Basic Books, 2000; Wilfley et al., Arch Gen Psychiatry, 8, 713-721, 2002; Elliott et al., Behav Res Ther, 48, 424-428, 2010) which posits that interpersonal problems lead to negative affect which, in turn, triggers disordered eating. METHOD The model was tested using data from 350 women obtained via an internet assessment method. Analyses examined direct and indirect effects, via depressive/negative affect, of interpersonal problems, including domains of affiliation and dominance on loss of control over eating, binge eating, and eating disorder psychopathology. RESULTS Interpersonal problems showed significant effects on binge eating and eating disorder psychopathology that were statistically mediated by depressive/negative affect. Affiliation showed significant effects on binge eating and eating disorder psychopathology with low affiliation effects statistically mediated by depressive/negative affect and high affiliation effects independent of depressive/negative affect. DISCUSSION These findings support the interpersonal model of binge eating and highlight the importance of examining specific types of interpersonal problems in understanding heterogeneity of individuals with eating disorder psychopathology.

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.

THE CONVERGENT AND DISCRIMINANT VALIDITY OF FIVE-FACTOR TRAITS: CURRENT AND PROSPECTIVE SOCIAL, WORK, AND RECREATIONAL DYSFUNCTION

Christopher J. Hopwood; Leslie C. Morey; Emily B. Ansell; Carlos M. Grilo; Charles A. Sanislow; Thomas H. McGlashan; John C. Markowitz; John G. Gunderson; Shirley Yen; M. Tracie Shea; Andrew E. Skodol

The convergent and discriminant validity of Five Factor Model (FFM) personality traits with concurrent and prospective social, work, and recreational dysfunction was assessed in a large, longitudinal clinical sample. Consistent with five factor theoretical expectations, neuroticism is broadly related to dysfunction across domains; extraversion is primarily related to social and recreational dysfunction; openness to recreational dysfunction; agreeableness to social dysfunction; and conscientiousness to work dysfunction. Findings support five factor theory and the clinical assessment of normative personality traits.
