Grandiose and vulnerable narcissism seem to be uncorrelated in empirical studies, yet they share at least some theoretical similarities. In the current study, we examine the relation between grandiose (conceptualized as admiration and rivalry) and vulnerable narcissism in the context of the Big Five personality traits and metatraits, self-esteem, and their nomological network. To this end, participants (N = 314) filled in a set of self-report measures via an online survey. Rivalry was positively linked with both admiration and vulnerable narcissism. We replicated the relations of admiration and rivalry with personality traits and metatraits—as well as extended existing knowledge by providing support for the theory that vulnerable narcissism is simultaneously negatively related to the Stability and Plasticity. Higher scores on vulnerable narcissism and rivalry predicted having fragile self-esteem, whereas high scores on admiration predicted having optimal self-esteem. The assumed relations with the nomological network were confirmed, i.e., vulnerable narcissism and admiration demonstrated a contradictory pattern of relation to shyness and loneliness, whilst rivalry predicted low empathy. Our results suggest that the rivalry is between vulnerable narcissism and admiration, which supports its localization in the self-importance dimension of the narcissism spectrum model. It was concluded that whereas admiration and rivalry represent the bright and dark face of narcissism, vulnerable narcissism represents its blue face.

BackgroundOrthorexia nervosa (ON) is defined as pathological healthful eating. The aim of this study was to investigate whether there is any difference in orthorexic behaviours between clinical and non-clinical groups, and in different cultural contexts. .MethodsRecruitment involved both female patients with anorexia nervosa (AN) and healthy controls (HC) from Italy and Poland (N = 23 and N = 35 AN patients; and N = 39 and N = 39 HCs, in Italy and Poland, respectively). Assessment of orthorexic behaviours was performed with the ORTO-15 test.ResultsStatistically significant differences were found between Italian women in the AN and HC group, whereas no difference between Polish women in the AN and HC group was found. Both Italian groups scored significantly higher than the Polish ones on the ORTO-15.ConclusionsDifferences have been found between the Italian and Polish samples, both in the percentage of individuals with orthorexic behaviours as suggested by an ORTO 15 score below the cutoff, and in the mean ORTO 15 scores in the AN and HC groups, suggesting cross-cultural differences in orthorexic behaviours, whose meaning is currently difficult to understand.

Narcissism, Machiavellianism and psychopathy are commonly referred to as the Dark Triad of personality. In the current study, we examined the structure of the Dark Triad measured by the Polish version of the Short Dark Triad (SD3). The study was conducted with 1012 individuals in Poland. The analyses were performed in four steps: (1) the external validity of the SD3 was tested to provide evidence that SD3 is a valid measure of the three dark traits; (2) the structural validity of the SD3 was tested using competing models in confirmatory factor analyses; (3) the structure of narcissism was tested; and (4) the combined bifactor model of Machiavellianism and psychopathy was tested. The results support the differentiation of the Dark Triad into a Dark Dyad (Machiavellianism and psychopathy) and narcissism, which can be used in further theoretical work and new operationalization of the Dark Triad.

SummaryThe Eating Attitudes Test (EAT) is one of the most commonly used measures of abnormal eating habits; however, it has been criticized for its unstable factorial structure. Different studies proposed different solutions, but as yet there is no consensus whether the three-, five-or seven-factor solution is appropriate. We examined the cues provided by previous studies that investigated the EAT structure, and tested our expectations on a nonclinical group of 617 women. Based on bi-factor confirmatory factor analysis, we demonstrated that the EAT measures general eating pathology as well as more specific factors, such as 'Social pressure', 'Food awareness', 'Food preoccupation' and 'Purging behaviors'. Among distinguished specific factors, 'Social pressure' seems to be a promising scale to be used for screening purposes. The 'Food awareness' factor could be interpreted in terms of orthorexia nervosa; however, further evidence is required to support this conclusion. We also provided evidence that 'Bulimia' and 'Food preoccupation' factors should be maintained within the EAT-26 as important behavioral aspects of eating pathology. These results shed new light on this measure and provide the basis for a discussion of its psychometric issues. EAT-26 structure/EAT-26 assessmentIt is well known that eating disorders (EDs) are prevalent and constitute significant health problems among young women [1]. There is evidence that effective eating disorder treatment does exist; however, findings from community studies indicate that only a minority of patients are in treatment [2]. This is a factor leading researchers to employ various screening strategies in order to estimate the prevalence of eating disorders as well as to detect cases for the purpose of earlier interventions [3]. One of the most widely used screening measures for eating disorders is the abbreviated version of the Eating Attitudes Test - . Three factors were distinguished: dieting, bulimia and food preoccupation, and oral control. Following the development of the EAT-26, screening studies of abnormal eating habits have proliferated [5], and this has raised questions regarding its psychometric properties.Although many studies of the psychometric properties of the EAT-26 exist, researchers have not been able to reach an agreement concerning its factor structure. Therefore, different versions of the EAT exist in the literature: comprising three factors [6][7][8], four factors [9][10][11], five factors [12,13] or seven factors [14]. Second, researchers often encounter items that do not load on any factor [7,8], items that cross-load on other scales [13], or items that weave between scales [10]. Third, the intercorrelations between distinguished factors are extremely high [11], which could be interpreted in terms of a general abnormal eating habits factor whose reliability estimates have been reported in numerous studies [15]. Failure in replication of the factor structure may be the result of sample selection, since the EAT was originally developed on a clinica...
