Functional altruism among agreeable and narcissistic donors

Given the increasing popularity of crowdsourced fundraisers, understanding how characteristics of funding initiatives and donors influence donations has critical real-world implications. Across two studies, we identified potential situational factors most conducive to successful crowdsourcing while also determining whether individual differences in various personality factors predicted differing levels of donation. Participants in Study 1 (MAge = 19.99; 309 women, 75 men) viewed descriptions that manipulated donation type (organizer donation, anonymous donation, no donation) and type of fundraiser (self-organized, other-organized), and reported their willingness to donate to an individual’s medical treatment and completed inventories assessing Big Five personality traits. In Study 2 participants (MAge = 20.22; 322 women, 102 men) viewed vignettes describing fundraisers for an individual’s vacation fun and completed inventories assessing participantslevels of narcissism using the Pathological Narcissism Inventory. Higher agreeableness in men predicted heightened donation interest, regardless of type of cause, particularly when someone else has already donated (Study 1). Unexpectedly, narcissistic men and women both reported heightened donation interest (Study 2). We frame these findings through a framework assessing the adaptive utility of altruism as a function of personality in modern donation contexts.

Description of the basic psychometric characteristics and the factor structure of the Greek version of the Pathological Narcissism Inventory

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.

The Pathological Narcissism Inventory: Measurement Invariance Across Serbian and USA Samples and Further Validation

The aim of this research was to explore measurement invariance across samples from Serbia and the USA (Study 1) and to further validate the Serbian adaptation of the Pathological Narcissism Inventory – PNI (Study 2). The results supported the original seven-factor first-order structure as well as the hierarchical structure of the PNI with Narcissistic grandiosity and vulnerability as the second-order factors. Further, scalar invariance between the two versions of the PNI was achieved. Relations between Narcissistic grandiosity and vulnerability and other measures of grandiose and hypersensitive narcissism supported the validity of their scores. Among HEXACO traits, both Narcissistic grandiosity and vulnerability showed substantial negative correlations with Honesty-Humility. The main distinctions between the two aspects of narcissism lie in the positive relations with Neuroticism and negative relations with self-esteem, both of which are higher for Narcissistic vulnerability. The results support good psychometric properties of the PNI scores and add to the PNI’s cross-cultural validity.

Modelling Pathological Narcissism Using the Brief PNI in Terms of Structure and Convergent and Divergent Validity: A New Perspective

The Pathological Narcissism Inventory (PNI) is a popular measure and the first to attempt to tap into both grandiose and vulnerable narcissism (GN/VN). However, data have raised questions as to whether it appropriately formulates GN and differentiates it from VN. In this study, we examined the Brief-PNI’s structure and construct validity, by using a novel model based on the theoretical notion of GN and VN sharing core features. Participants ( N = 1,061) completed the Brief-PNI, and psychological distress and social avoidance questionnaires. Results showed a better fit and differentiation of GN and VN for a model with cross-loading of shared first-order factors on GN and VN, compared with the traditional PNI structure. We concluded that the Brief-PNI can offer an appropriate formulation and differentiation of VN and GN, provided that their shared variance is considered.

Measurement Invariance of Three Narcissism Questionnaires Across the United States, the United Kingdom, and Germany

With a recent surge of research on narcissism, narcissism questionnaires are increasingly being translated and applied in various countries. The measurement invariance of an instrument across countries is a precondition for being able to compare scores across countries. We investigated the cross-cultural measurement invariance of three narcissism questionnaires (Brief Pathological Narcissism Inventory [B-PNI], Narcissistic Personality Inventory [NPI], and Narcissistic Admiration and Rivalry Questionnaire [NARQ]) and mean-level differences across samples from the United States ( N = 2,464), the United Kingdom ( N = 307), and Germany ( N = 925). Overall, the B-PNI and NARQ functioned equivalently for the U.S. and U.K. participants. More violations of measurement invariance were found between Germany and the combined U.S. and U.K. samples, and for the NPI. In the B-PNI and NARQ, Americans scored higher than individuals from the United Kingdom regarding agentic aspects (self-sacrificing self-enhancement, admiration), while Germans scored lower than both Americans and U.K. individuals regarding antagonistic (entitlement rage, rivalry) and neurotic (hiding the self, contingent self-esteem) aspects. More inconsistent results were found for NPI facets. When noninvariance was present, observed means yielded biased results. Thus, the degree of measurement invariance across translated instrument versions should be considered in cross-cultural comparisons, even with culturally similar countries.
