The Pathological Narcissism Inventory (PNI) is a recently developed measure for assessing grandiose and vulnerable themes of narcissistic pathology. The aim of this study was to validate the PNI in the transitional post-war Croatian society by examining its psychometric properties and factor structure in a sample of Croatian university students (N=651). The participants filled out several self-report measures of narcissism, as well as measures of trait emotional stability and negative emotional states. Findings of this study supported the existence of seven first-order and two second-order factors of the PNI, invariant across genders. Additionally, all the subscales had good reliability coefficients, while the associations with other measures supported the concurrent validity of the instrument. These findings support the use of the PNI in a transitional post-war society and emphasize certain aspects of cross-cultural stability of pathological narcissism, although some crosscultural variants should be considered when applying this measure in different cultural settings.
Narcissistic Personality Inventory – Possibility of Application on a Serbian Population
Facta Universitatis, Series: Philosophy, Sociology, Psychology and History
The main goal of this research was to investigate some of the psychometric properties of the Narcissistic Personality Inventory – reliability, applicability of a seven-factor structure and its construct validity for a sample of the Serbian population. For this purpose, a 40-item Narcissistic Personality Inventory – NPI and Rosenberg’s Global Self-esteem scale were distributed via internet to 150 participants of both sexes, aged 19 – 56. Investigation of internal consistency of NPI was satisfactory – Cronbach alpha coefficient was 0.87. Also, the seven-factor structure of NPI found with the American sample did not correspond well to the factor structure found in the present study. The total scale score correlated with self-esteem, thereby supporting the validity of the scale.
The aim of this study was to examine the basic psychometric properties of the Greek version of the Pathological Narcissism Inventory (PNI; Pincus, Ansell, Pimentel, Cain, Wright & Levy, 2009). The PNI is a self-report scale recently developed to measure both narcissistic grandiosity (Exploitativeness, Grandiose Fantasy, Self-sacrificing Selfenhancement) and narcissistic vulnerability (Contingent Self-esteem, Hiding the Self, Devaluing, Entitlement rage). The English version of the PNI was translated to Greek and administered to 283 University students. Confirmatory factor analysis was used to investigate its factor structure in the Greek sample. Several models were evaluated: a. the initial seven-factor first-order model, b. three second-order models with two secondorder latent factors (Grandiosity, Vulnerability), c. three second-order models with three higher order latent factors (Grandiosity, Vulnerability, Malignancy). Goodness-of-fit indices showed better fit for the seven-factor structure, however, acceptable fit was also achieved for most of the second-order models as well. Reliability coefficients were within the acceptable standards for all subscales. The models are evaluated theoretically and the advantages of assessing narcissism in Greece with the PNI are discussed.
Development of a Brief Version of the Pathological Narcissism Inventory
Psychological Assessment, 2015
With theoretical and empirical interest in narcissism growing, there is a need for brief measures of pathological narcissism that can be used more practically while assessing the construct comprehensively. Data from four samples (total N ϭ 3,851) collected across two separate research groups and representing undergraduate, community, and clinical populations were used to establish the reliability, validity, and utility of the Brief-Pathological Narcissism Inventory (B-PNI). Item response theory and confirmatory factor analyses were used to determine the best-performing 28 items from the original PNI and ensure that the B-PNI exhibited a factor structure consistent with the original PNI. Items were retained for all seven pathological narcissism facet scales. Additional results also support the criterion validity of the B-PNI, suggesting that it can be used in place of the original PNI to assess the various facets of pathological narcissism effectively and without loss of information, which may enhance the ability of researchers to investigate pathological narcissism in future work.

This study intends to examine the psychometric properties of the Turkish version of the short form of the Five-Factor Narcissism Inventory (FFNI-SF). The study group consists of a total of 526 university students (54% were female) whose ages range from 18 to 32. In the translational equivalence study made over a two-week interval, the FFNI-SF scores showed high consistency. Cronbach' s alpha was found to be .87 for the total score, and the alphas for the FFNI-SF subscales ranged from .57 to .79. Corrected item-subscale correlations for the items ranged from .22 to .73. Confirmatory factor analysis results have shown that among the three competing models derived from the conceptual models, Model 1 with 15 factors had the best goodness-of-fit to the data, □ 2 = 3851.48, df = 1605, □ 2 /sd = 2.40, RMSEA = .057, AGFI = .74, GFI = .77, CFI = .77, NNFI = .75. The correlation of total scores from the Narcissistic Personality Inventory (NPI) and FFNI-SF was .65, p < .01. Study results indicated that the Turkish version of the FFNI-SF may serve as a useful tool in assessing narcissistic personality traits in non-clinical samples.
The Higher Order Factor Structure and Gender Invariance of the Pathological Narcissism Inventory
Assessment, 2010
The Pathological Narcissism Inventory (PNI) is a recently developed multidimensional inventory for the assessment of pathological narcissism. The authors describe and report the results of two studies that investigate the higher order factor structure and gender invariance of the PNI. The results of the first study indicate that the PNI has a higher order factor structure that conforms to the theoretical structure of pathological narcissism with one factor representing narcissistic grandiosity and the other capturing narcissistic vulnerability. These results uniquely place the PNI as the only measure to broadly assess the two phenotypic themes of pathological narcissism. In the second study, results from tests of measurement invariance indicate that the PNI performs similarly in large samples of men (n = 488) and women (n = 495). These results further establish the psychometric properties of the PNI and suggest that it is well suited for the assessment of pathological narcissism.
Initial Construction and Validation of the Pathological Narcissism Inventory
Psychological Assessment, 2009
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.
Evidence for the Criterion Validity and Clinical Utility of the Pathological Narcissism Inventory
Assessment, 2012
In this study we evaluated aspects of criterion validity and clinical utility of the grandiosity and vulnerability components of the Pathological Narcissism Inventory (PNI) using two undergraduate samples (Ns = 299, 500). Criterion validity was assessed by evaluating the correlations of narcissistic grandiosity and narcissistic vulnerability with established indices of normal personality traits, psychopathology and clinical concerns, and pathological personality traits. Overall, the pattern of correlations supported the convergent and discriminate validity of grandiose and vulnerable conceptualizations of pathological narcissism as measured by the PNI. Clinical utility was assessed by evaluating the extent to which clinicians without specific training in pathological narcissism as well as clinicians with expertise in pathological narcissism could accurately predict the correlates of PNI grandiosity and vulnerability with normal and pathological personality traits and psychopathology. The r contrast-cv coefficient provided a global index of accuracy in clinicians' predictions that was more fully elaborated by examining systematic discrepancies across groups. Overall, novice and expert clinicians were generally able to predict criterion correlations, with some exceptions (e.g., counter to predictions, pathological narcissism was negatively associated with treatment resistance). These results provide further evidence regarding the validity and utility of the narcissistic grandiosity and narcissistic vulnerability constructs as measured by the PNI.
