A Comparison of the Nomological Networks Associated With Forced-Choice and Likert Formats of the Narcissistic Personality Inventory

The Narcissistic Personality Inventory (NPI) is one of the most popular measures of narcissism. However, its use of a forced-choice response set might negatively affect some of its psychometric properties. The purpose of this research was to compare a Likert version of the NPI, in which only the narcissistic response of each pair was given, to the original NPI, in 3 samples of participants (N = 1,109). To this end, we compared the nomological networks of the forced-choice and Likert formats of the NPI in relation to alternative measures of narcissism, narcissistic personality disorder, entitlement, self-esteem, general personality traits (reported by self and informants), interpersonal styles, and general pathological traits included in the DSM–5. The Likert format NPI—total and subscales—manifested similar construct validity to the original forced-choice format across all criteria with only minor differences that seem to be due mainly to the increased reliability and variability found in the Likert NPI Entitlement/Exploitativeness subscale. These results provide evidence that a version of the NPI that employs a Likert format can justifiably be used in place of the original.     

Let Go of Your (Inflated) Ego: Caring more about Others Reduces Narcissistic Tendencies

Narcissists are known for having excessively positive self‐views, but an equally defining characteristic of narcissism may be a disregard of other people. Could encouraging people to care more about others, or feel more connected to them, reduce narcissism? We describe a series of studies demonstrating that a more communal focus on others reduces narcissistic tendencies. In particular, repeating communal self‐statements (i.e., “I am a caring person”), recalling a time when one was caring, feeling empathy, focusing on monetary expenditures (which increases a sense of dependence on others), and interdependent self‐construal all situationally reduce narcissism. These effects occur on a small scale but are significant because they establish that communal focus causes changes in narcissism. They also suggest that narcissism may have a state‐like or context‐dependent component, fluctuating across time and situations. Everyone may have the propensity to be narcissistic, but caring more about others may help to curb narcissism.     

Narcissism and celebrity

We used the Narcissistic Personality Inventory (NPI) to assess the degree of narcissism among celebrities. Results indicate that celebrities are significantly more narcissistic than MBA students and the general population. Contrary to findings in the population at large, in which men are more narcissistic than women, female celebrities were found to be significantly more narcissistic than their male counterparts. Reality television personalities had the highest overall scores on the NPI, followed by comedians, actors, and musicians. Further, our analyses fail to show any relationship between NPI scores and years of experience in the entertainment industry, suggesting that celebrities may have narcissistic tendencies prior to entering the industry.     

Narcissism and Performance on Behavioral Decision‐making Tasks

Three studies examined narcissism and behavioral decision making. Decision‐making tasks included the Iowa Gambling Task (IGT; Studies 1–3), Balloon Analogue Risk Task (Studies 1–3), Columbia Card Task (CCT; Studies 2 and 3), and Game of Dice Task (Study 3). To tease apart the contributions of grandiose narcissism (i.e., narcissism found in the general population), pathological narcissism, and narcissistic traits (i.e., grandiosity, entitlement, and exploitativeness) in decision making, we assessed grandiose narcissism in Studies 1 (n = 380) and 2 (n = 244), pathological narcissism in Study 2, and the narcissistic traits in Study 3 (n = 312). Grandiose and pathological narcissism failed to predict decision making regardless of whether or not decision making included immediate feedback. In Study 3, the narcissistic trait of grandiosity (i.e., having an inflated sense of self‐importance) was associated with greater risk taking on the CCT‐hot (i.e., provided immediate feedback), and entitlement was associated with greater risk taking on the IGT. Measurement and applied implications are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

自恋与心理健康:适应性自恋与病理性自恋的不同作用

目的:探讨适应性自恋与病理性自恋对个体心理健康的不同影响。方法:750名大学生完成了一套由自恋人格问卷(NPI)、病理性自恋量表(PNI)和症状自评量表(SCL-90)组成的测验。利用结构方程模型对变量间的关系进行分析。结果表明:病理性自恋的二阶因子自恋易损性对个体心理健康具有显著的负向预测作用,自恋易损性水平越高,个体心理健康水平越低。自恋夸大性和适应性自恋(自恋人格问卷,NPI)对心理健康的正向预测作用达到边缘显著,自恋夸大性和适应性自恋得分越高,心理健康水平越高。结论:病理性自恋的二阶因子自恋易损性对心理健康具有明显的破坏作用,而自恋夸大性和正常/适应性自恋可能对心理健康存在微弱的保护作用。     

Cross‐cultural invariance of NPI‐13: Entitlement as culturally specific,leadership and grandiosity as culturally universal

The current study explores the problem with the lack of measurement invariance for the Narcissistic Personality Inventory (NPI) by addressing two issues: conceptual heterogeneity of narcissism and methodological issues related to the binary character of data. We examine the measurement invariance of the 13‐item version of the NPI in three populations in Japan, Poland and the UK. Analyses revealed that leadership/authority and grandiose exhibitionism dimensions of the NPI were cross‐culturally invariant, while entitlement/exploitativeness was culturally specific. Therefore, we proposed NPI‐9 as indicating scalar invariance, and we examined the pattern of correlations between NPI‐9 and other variables across three countries. The results suggest that NPI‐9 is valid brief scale measuring general levels of narcissism in cross‐cultural studies, while the NPI‐13 remains suitable for research within specific countries.     

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.     

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.     

Equivalence of Narcissistic Personality Inventory constructs and correlates across scoring approaches and response formats

The prevalent scoring practice for the Narcissistic Personality Inventory (NPI) ignores the forced-choice nature of the items. The aim of this study was to investigate whether findings based on NPI scores reported in previous research can be confirmed when the forced-choice nature of the NPI’s original response format is appropriately modeled, and when NPI items are presented in different response formats (true/false or rating scale). The relationships between NPI facets and various criteria were robust across scoring approaches (mean score vs. model-based), but were only partly robust across response formats. In addition, the scoring approaches and response formats achieved equivalent measurements of the vanity facet and in part of the leadership facet, but differed with respect to the entitlement facet.     

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.     

A CONCEPTUAL AND EMPIRICAL REEXAMINATION OF THE MEASUREMENT OF THE SOCIAL DESIRABILITY OF ITEMS: IMPLICATIONS FOR DETECTING DESIRABLE RESPONSE STYLE AND SCALE DEVELOPMENT

This paper calls into question traditional methods of measuring the social desirability of items and their use in scale construction. First, we make explicit that the proper focus for desirability studies of items and traits are the rated desirabilities of the alternative item responses indicating different trait levels. Second, the results from our first study show that the relation between degree of endorsement of an item and its judged desirability level is often nonlinear and varies across items such that no general model of item desirability can be adopted that will accurately represent the relations across all items, traits, and trait levels. In addition, the nature of these relationships can vary depending on whether desirability is considered in a work or general context. Third, results from a second study indicate specifically that people when instructed to self-present in a maximally desirable manner will choose for some attributes a moderate level of endorsement (e.g., "agree") rather than a more extreme response option (e.g., "strongly agree"). Subjects offer several different reasons for viewing the less extreme response options, which yield more moderate trait level scores, as more desirable. These reasons are linked to perceptions of the more extreme response option as being associated with negative behaviors and concerns about how others will view a more extreme response to the item. Both studies indicate that desirable responding to personality items is more complex than previously believed.     

Narcissistic Personality Inventory: Structure of the adapted Dutch version

Barelds, D. P. H. & Dijkstra, P. (2009). Narcissistic Personality Inventory: Structure of the adapted Dutch version. Scandinavian Journal of Psychology, 51, 132–138. The present study examined the structure of a Dutch adaptation of the 40‐item Narcissistic Personality Inventory ( Raskin & Terry, 1988 ) in a community sample (n = 460) and a student sample (n = 515). Altering the response format of the NPI to a Likert‐scale had no apparent effect on the responses. Confirmatory factor analyses supported neither the four‐factor structure reported by Emmons (1984) , nor the seven‐factor structure reported by Raskin and Terry (1988) . Instead, exploratory factor analyses supported either a single‐factor solution (general narcissism), or a two‐factor solution (Authority/Power and Self‐Admiration). The validity of the NPI was supported by its relations with sex, age, personality, self‐esteem, shame, guilt and social desirability.     

An introduction to mixture item response theory models

Mixture item response theory (IRT) allows one to address situations that involve a mixture of latent subpopulations that are qualitatively different but within which a measurement model based on a continuous latent variable holds. In this modeling framework, one can characterize students by both their location on a continuous latent variable as well as by their latent class membership. For example, in a study of risky youth behavior this approach would make it possible to estimate an individual's propensity to engage in risky youth behavior (i.e., on a continuous scale) and to use these estimates to identify youth who might be at the greatest risk given their class membership. Mixture IRT can be used with binary response data (e.g., true/false, agree/disagree, endorsement/not endorsement, correct/incorrect, presence/absence of a behavior), Likert response scales, partial correct scoring, nominal scales, or rating scales. In the following, we present mixture IRT modeling and two examples of its use.

An interaction model for the role of self-evaluations and antagonistic pursuits in subjective well-being

Popular theorizing about happiness pursuit emphasizes universal paths to happiness, but other theorizing acknowledges different people achieve happiness in different ways (i.e., subjective well-being, SWB). The present work extended this latter perspective by examining how antagonistic pursuit of a grandiose identity (‘narcissistic antagonism’) – generally thought to reduce narcissistic people’s SWB – may relate to increased cognitive well-being (i.e., a component of SWB) for narcissistic people with lower self-esteem. In Study 1, participants (N = 417) reported their narcissism, self-esteem, narcissistic antagonism, and general life satisfaction (to index cognitive well-being). In Study 2 (pre-registered), participants (N = 450) reported their narcissism, self-esteem, narcissistic antagonism, general and domain-specific life satisfaction, and general affect (to index affective well-being, which is a different component of SWB). Both studies revealed narcissistic antagonism related to increased life satisfaction only for more (vs. less) narcissistic people with lower (vs. higher) self-esteem. Study 2 not only replicated this interactive pattern on satisfaction across various life domains but also revealed the interaction may be related to increased negative affect. Broadly, results highlight how different people may enhance features of SWB in different, even ‘dark’, ways.     

The Wax and Wane of Narcissism: Grandiose Narcissism as a Process or State

Though grandiose narcissism has predominantly been studied in structural terms—focused on individuals' general tendencies to be more or less narcissistic—we tested whether it also has a meaningful process or state component. Using a daily diary study methodology and multilevel modeling (N = 178 undergraduates, 146 female; M_age = 18.86, SD = 2.21), we examine whether there is significant variability in daily state narcissism and whether this variability relates systematically to other psychological states (i.e., self‐esteem, stress) and daily events. We assessed state narcissism and daily experiences over a 10‐day period. We observed significant within‐person variability in daily narcissism. Notably, this variability was not simply random error, as it related systematically to other psychological states and daily events. Specifically, state narcissism was higher when people experienced more positive agentic outcomes (e.g., having power over someone) or more positive communal outcomes (e.g., helping someone with a problem). State narcissism was lower on days people experienced greater felt stress. These relations held when state self‐esteem, gender, and trait narcissism were controlled. These findings suggest that grandiose narcissism has a meaningful process or state component.     

Mapping the scale of the narcissism epidemic: Increases in narcissism 2002–2007 within ethnic groups

[Twenge, J. M., Konrath, S., Foster, J. D., Campbell, W. K., & Bushman, B. J. (2008a). Egos inflating over time: A cross-temporal meta-analysis of the Narcissistic Personality Inventory. Journal of Personality, 76, 875–901.] found that Narcissistic Personality Inventory (NPI) scores increased between 1982 and 2006 among college students nationwide, but [Trzesniewski, K. H., Donnellan, M. B., & Robins, R. W. (2008). Do today’s young people really think they are so extraordinary? An examination of secular changes in narcissism and self-enhancement. Psychological Science, 19, 181–188.] found that NPI scores remained unchanged over that time in samples from the University of California (UC) campuses. The increasing numbers of Asian-Americans at the UCs over time may have masked changes in narcissism, as Asian-Americans score lower on the NPI. When examined within ethnic groups, Trzesniewski et al.’s data show that NPI scores increased significantly between 2002 and 2007 at twice the rate of the yearly change found over 24 years in Twenge et al. (2008a). The overall means also show a significant increase 2002–2007. Thus the available evidence suggests that college students are endorsing progressively more narcissistic personality traits over the generations.     

孤芳自赏还是乐于助人?员工自恋对亲社会行为的影响

本研究通过整合自恋双元理论和特质激活理论, 探讨欣赏型自恋、敌对型自恋对员工亲社会行为的影响机制, 深入分析了员工关系趋近型动机和关系回避型动机的中介作用以及任务相互依赖性的调节作用。通过对来自员工-同事二阶段配对的235份数据进行分析, 结果发现: 欣赏型自恋对员工亲社会行为具有显著的正向影响, 敌对型自恋对员工亲社会行为具有显著的负向影响; 关系趋近型动机在欣赏型自恋与员工亲社会行为之间发挥着中介作用, 关系回避型动机在敌对型自恋与员工亲社会行为之间没有发挥中介作用; 任务相互依赖性不仅正向调节欣赏型自恋与员工关系趋近型动机的直接效应, 而且还正向调节着欣赏型自恋通过关系趋近型动机对亲社会行为的间接效应。     

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.
