Comparing clinical and social-personality conceptualizations of narcissism

There is a lack of consensus surrounding the conceptualization of narcissism. The present study compared two measures of narcissism-one used in clinical settings (Personality Diagnostic Questionnaire, PDQ-4+; Hyler, 1994) and one used in social-personality research (Narcissistic Personality Inventory, NPI; Raskin & Terry, 1988)-across two samples. Sample 1 (N=271) was composed of undergraduates, whereas Sample 2 (N=211) was composed of parents of the Sample 1 participants. The scales were significantly interrelated but manifested divergent relations with general personality traits, personality disorders (including expert prototypal ratings of narcissism), recollections of parenting received, and psychological distress and self-esteem. PDQ-4 narcissism captured an emotionally unstable, negative-affect-laden, and introverted variant of narcissism; NPI narcissism captured an emotionally resilient, extraverted form. The clinical and social-personality conceptualizations of narcissism primarily share a tendency to use an antagonistic interpersonal style. Implications for the DSM-V are discussed.     

Further assessment of the construct validity of four measures of narcissism: replication and extension

CT. The authors build on earlier research by L. S. Mullins and R. E. Kopelman (1988) and R. E. Kopelman and L. S. Mullins (1992) to reexamine the construct validity of four narcissism scales: the Margolis-Thomas Measure of Narcissism (MT; H. D. Margolis & V. A. Thomas, 1980), the Narcissistic Personality Disorder Scale (NPDS; H. U. Ashby, R. R. Lee, & E. H. Duke, 1979), the Narcissism-Hypersensitivity subscale of the MMPI, Scale 5, Masculinity-Femininity (NHMF; K. Serkownek, 1975), and the Narcissistic Personality Inventory (NPI; R. Raskin & C. S. Hall, 1979). The present analysis included the revised NPI and its factors along with four measures of satisfaction and a number of other previously assessed variables. The MT exhibited the strongest validity, correlating positively with conceptually related constructs such as Machiavellianism, nonsignificantly with unrelated measures like the need to achieve, and inversely with all four satisfaction scales. Contrasts between the NPI and NPDS and NHMF seemed to parallel recent differentiations between overt and covert narcissism, but data for the NPI factors suggested instead that the four narcissism scales helped describe a complex psychological continuum related to adjustment.     

Narcissism and the non-equivalence of self-esteem measures: A matter of dominance?

Previous research reveals a substantial degree of variability in the extent to which narcissism (as measured by the Narcissistic Personality Inventory or NPI; Emmons, 1987) and self-esteem (measured using a variety of self-report scales) are associated. Data from 329 college students provided support for the hypothesis that the variability in associations between narcissism and different measures of self-esteem may be explained in part by the degree to which a given self-esteem measure is related to dominance. These results have important implications for research on narcissism and self-esteem, as well as the broader issue of how self-esteem is conceptualized and measured in psychological research.     

Comparing the construct validity of scales derived from the Narcissistic Personality Inventory: A reply to

Rosenthal and Hooley (2010) suggested that the Narcissistic Personality Inventory (NPI) includes items that are tangential to narcissism. They demonstrated that the removal of these items resulted in scores that are not confounded by self-esteem. We tested whether NPI scales derived from Rosenthal and Hooley’s included (NPI-N) and excluded (NPI-X) items manifest divergent relations with self-esteem, entitlement, distress, NPD, and general traits in two samples of undergraduates. The scales generated similar patterns of correlations, although the NPI-N items were more strongly related to (dis)Agreeableness, whereas the NPI-X items were more strongly related to Extraversion. Ultimately, the NPI-X items bore significant relations to constructs central to grandiose narcissism and do not seem to have caused problems in the assessment of narcissism.     

Exploring the relationship between two forms of narcissism and competitiveness

This study investigated the theoretical and empirical links between narcissism and competitiveness by focusing on the multifaceted features of these individual difference variables. The present study compared measures of overt narcissism (Narcissistic Personality Inventory, NPI; Raskin & Terry, 1988) and covert narcissism (Hypersensitive Narcissism Scale, HSNS; Hendin & Cheek, 1997) with measures of competitiveness (Revised Competitiveness Index, CI-R; Houston, Harris, McIntire, & Francis, 2002) and hypercompetitiveness (Hypercompetitive Attitude Scale, HCS; Ryckman, Hammer, Kaczor, & Gold, 1990). Based on a sample of 324 undergraduates, positive relationships were found between overt narcissism and general competitiveness and hypercompetitiveness. However, covert narcissism was negatively related to general competitiveness but positively related to hypercompetitiveness. The findings highlight the similarities and distinctions between different forms of narcissism and competitiveness and provide a broader framework for understanding the relationship between narcissism and competitiveness. Implications for the interpersonal manifestation of these different forms are discussed.     

Is the Narcissistic Personality Inventory still relevant? A test of independent grandiosity and entitlement scales in the assessment of narcissism

Some scholars have called for the replacement of the Narcissistic Personality Inventory (NPI) with more narrow scales measuring grandiosity and entitlement instead. In the current study, the authors examined the relations among the NPI and measures of grandiosity and entitlement, as well as in relation to a measure of the Five-Factor Model (FFM). The NPI manifested significant correlations with the alternative scales of entitlement and grandiosity and relatively similar patterns of correlations with the FFM traits. Of note, the NPI manifested significant incremental validity in the prediction of several FFM traits that are central to the conceptualization of narcissism. These findings suggest that some caution must be used before assuming that these lower-order scales can be used to replace the NPI in the assessment of narcissism.     

Three narcissism scales for the California Q-set.

Three observer-based narcissism scales were developed from factor scores based on a California Q-set (CAQ) narcissism prototype. Each of the three scales--Willfulness, Hypersensitivity, and Autonomy--correlated with observer and self-report narcissism measures in the derivation sample of 105 women and a cross-validation sample of 175 men and 175 women. California Psychological Inventory (CPI), Adjective Check List (ACL), and Minnesota Multiphasic Personality Inventory (MMPI) correlates and partner ACL ratings suggested that the Willfulness scale represents self-assuredness, rebelliousness, and exhibitionism characteristic of overt or phallic narcissism. The correlates of the Hypersensitivity scale included depression and introversion along with rebelliousness and hostility, indicative of covert narcissism. The Autonomy scale was correlated positively with creativity, empathy, achievement-orientation, and individualism, and thus assesses a healthy variant of narcissism.     

Narcissism and Cardiovascular Reactivity to Rejection Imagery1

This study examined the interactive effects of imagined rejection and narcissism on cardiovascular reactivity (CVR). Participants completed measures of overt narcissism (Narcissistic Personality Inventory, NPI; Raskin & Hall, 1979 ), overt–covert narcissism ( Margolis & Thomas, 1980 ), and trait self‐esteem. They then imagined 2 scenarios culminating in either interpersonal acceptance or rejection. Systolic (SBP) and diastolic blood pressure (DBP) and heart rate (HR) were assessed before, during, and after the imagery. Overt–covert narcissism was positively associated with task increases in SBP and DBP and recovery elevation of HR following rejection, but not acceptance. Similar effects on SBP were found for the Entitlement/Exploitativeness dimension of the NPI. Lower self‐esteem predicted greater task increases in SBP, DBP, and HR across conditions. Implications for health are discussed.     

Narcissism and empathy: validity evidence for the Narcissistic Personality Inventory

Three empathy questionnaires were correlated with scores on the Narcissistic Personality Inventory (NPI), and the predicted negative relationship was observed in two of the three cases. In addition, the Exploitiveness/Entitlement (E/E) subscale of the NPI was inversely related to all three empathy scales and directly related to another hypothesized measure of narcissism. Unexpected negative correlations between the E/E subscale and social desirability scales were interpreted as evidence of E/E subscale sensitivity to the manipulative dimension of narcissistic relationship styles. These data further support the construct validity of the NPI in general and of the Exploitiveness/Entitlement subscale in particular.     

What Does the Narcissistic Personality Inventory Measure Across the Total Score Continuum?

The Narcissistic Personality Inventory (NPI) is the most widely used measure of narcissism in the social-personality psychology literature. It contains 40 items that tap into a variety of traits that theoretically comprise narcissism, such as feelings of superiority and willingness to exploit others. Most researchers focus on the total score produced by the NPI and may logically assume that increments in total NPI score correspond with similar increments in underlying narcissism traits. However, research presented in this article suggests that the traits measured by the NPI do not increment at the same rate. Traits reflecting intrapersonally healthy qualities (e.g., leadership, superiority) increment most rapidly within the lower portions of the NPI total score continuum, whereas traits reflecting interpersonally harmful qualities (e.g., entitlement, exploitativeness) increment most rapidly within the upper portions of the NPI continuum. These differences have implications for the meaning of scores on the NPI and how they correlate with other variables. For example, we demonstrate that lower NPI scores best predict self-esteem and higher NPI scores best predict psychopathy.     

Narcissism and body image

This research examined the relationship between narcissism, as measured by the Narcissistic Personality Inventory (NPI; Raskin & Hall, 1979), and body image, as measured by the Body-Self Relations Questionnaire ( Winstead & Cash, 1984), in a nonclinical sample of college students. Also examined were narcissism's relationships to masculinity, femininity, and self-esteem. Results indicated that more narcissistic individuals had more favorable body images and were higher in masculinity and self-esteem. No gender differences were observed in either the levels of narcissism or its body image correlates. Overall, the findings suggest that the NPI measures “adjusted” narcissism rather than the “maladaptive” narcissism emphasized in theoretical and clinical accounts of the construct.     

A comparison of Agreeableness scores from the Big Five Inventory and the NEO PI-R: consequences for the study of narcissism and psychopathy

Despite being significantly correlated, there is evidence to suggest that the scales measuring Agreeableness from the Big Five Inventory (BFI) and the Revised NEO Personality Inventory (NEO PI-R) do not capture identical constructs. More specifically, NEO PI-R Agreeableness contains content related to "honesty and humility" that is not contained by the BFI. In a sample of undergraduates (N = 290), the authors compared the correlations between these two measures of Agreeableness with traits from the HEXACO-PI-R as well as measures of narcissism, narcissistic personality disorder, and psychopathy. As expected, the two scores were significantly correlated but NEO PI-R Agreeableness manifested stronger correlations with the domains/facets of Honesty-Humility, narcissism/NPD, and aspects of psychopathy; these differences appear to be due primarily to the inclusion of the NEO PI-R facets of Straightforwardness and Modesty. These differences have important implications for the assessment and conceptualization of personality and personality disorder.     

Egos inflating over time: a cross-temporal meta-analysis of the Narcissistic Personality Inventory

ABSTRACT A cross-temporal meta-analysis found that narcissism levels have risen over the generations in 85 samples of American college students who completed the 40-item forced-choice Narcissistic Personality Inventory (NPI) between 1979 and 2006 (total n =16,475). Mean narcissism scores were significantly correlated with year of data collection when weighted by sample size (β=.53, p <.001). Since 1982, NPI scores have increased 0.33 standard deviation. Thus, almost two-thirds of recent college students are above the mean 1979–1985 narcissism score, a 30% increase. The results complement previous studies finding increases in other individualistic traits such as assertiveness, agency, self-esteem, and extraversion.     

The five-factor narcissism inventory: a five-factor measure of narcissistic personality traits

This study provides convergent, discriminant, and incremental validity data for a new measure of narcissistic personality traits created from the perspective of the Five-factor model (FFM) of general personality structure. Fifteen scales were constructed as maladaptive variants of respective facets of the FFM (e.g., Reactive Anger as a narcissistic variant of angry hostility), with item selection made on the basis of a criterion-keying approach using results from 167 undergraduates. On the basis of data from 166 additional undergraduates, the convergent validity of these 15 scales was tested with respect to 8 established measures of narcissism (including measures of both grandiose and vulnerable narcissism) and the respective facets of the FFM. Discriminant validity was tested with respect to facets from other FFM domains. Incremental validity was tested with respect to the ability of the FFM narcissism trait scales to account for variance in 2 alternative measures of narcissism, after variance accounted for by respective NEO PI-R facet scales and other established measures of narcissism were first removed. The findings support the validity of these new scales as measures of narcissistic personality traits and as maladaptive variants of the FFM.     

Disagreeable narcissism mediates an effect of BAS on addictive behaviors

Some forms of personality dysfunction that are associated with substance use and other externalizing behaviors, such as Narcissistic Personality Disorder, are characterized by low five-factor Agreeableness. Low Agreeableness and high Extraversion are both associated with the Behavioral Approach System in the revised Reinforcement Sensitivity Theory of Personality (RST; McNaughton & Corr, 2008). Meta-analyses examining personality predictors of Substance Use Disorders (Kotov et al., 2010) and Pathological Gambling (MacLaren et al., 2011) have implicated low Agreeableness but not Extraversion. In the present study, we sampled undergraduate students (N = 346) to examine relationships between two aspects of grandiose narcissism measured by the Narcissistic Personality Inventory (NPI), approach motivation measured by the BIS/BAS scales, and self-reported addictive behaviors. Disagreeable and Extraverted subscales of the NPI were examined for possible mediation of associations between BAS and addictive behaviors. The more disagreeable aspect of narcissism mediated the effects of BAS on drug use, gambling, sex, and maladaptive intimate relationships. These results suggest that one mechanism through which the Behavioral Approach System may promote addictive behavior among grandiose Narcissists is through its association with their aggressive and antagonistic interpersonal style.     

Grandiose and vulnerable narcissism: a nomological network analysis

Evidence has accrued to suggest that there are 2 distinct dimensions of narcissism, which are often labeled grandiose and vulnerable narcissism. Although individuals high on either of these dimensions interact with others in an antagonistic manner, they differ on other central constructs (e.g., Neuroticism, Extraversion). In the current study, we conducted an exploratory factor analysis of 3 prominent self-report measures of narcissism (N=858) to examine the convergent and discriminant validity of the resultant factors. A 2-factor structure was found, which supported the notion that these scales include content consistent with 2 relatively distinct constructs: grandiose and vulnerable narcissism. We then compared the similarity of the nomological networks of these dimensions in relation to indices of personality, interpersonal behavior, and psychopathology in a sample of undergraduates (n=238). Overall, the nomological networks of vulnerable and grandiose narcissism were unrelated. The current results support the need for a more explicit parsing of the narcissism construct at the level of conceptualization and assessment.
