The Mini-IPIP, a 20-item short form of the 50-item International Personality Item Pool-Five-Factor Model measure (Goldberg, 1999), was developed and validated across five studies. The Mini-IPIP scales, with four items per Big Five trait, had consistent and acceptable internal consistencies across five studies (= at or well above .60), similar coverage of facets as other broad Big Five measures (Study 2), and test-retest correlations that were quite similar to the parent measure across intervals of a few weeks (Study 4) and several months (Study 5). Moreover, the Mini-IPIP scales showed a comparable pattern of convergent, discriminant, and criterion-related validity (Studies 2-5) with other Big Five measures. Collectively, these results indicate that the Mini-IPIP is a psychometrically acceptable and practically useful short measure of the Big Five factors of personality.

    ABSTRACT: Extraversion has exhibited inconsistent relationships with employees’ interpersonal citizenship. Across three studies, we integrate literature on personality with impression management and socioanalytic theories to propose that employees’ impression management motives act as a contingency, strengthening the relationship between extraversion and interpersonal citizenship. First, in Studies 1 and 2, across two settings (field and university) and two designs (nonexperimental and experimental), we confirm that extraverted individuals engage in citizenship to a greater extent when they are also either predisposed (Study 1) or cued (Study 2) to manage others’ impressions. In Study 3, we extend these findings by using a conditional mediation process model to develop and test the hypothesis that an individual’s strategy to get along serves as an explanatory mechanism to the interactive effect of extraversion and impression management motives on interpersonal citizenship. Overall, our results suggest that the prediction of interpersonal citizenship can be improved when considering the conjoint influence of employees’ extraversion and impression management motives.

Alpha reliabilities for the Mini-IPIP in the present sample were for the most part acceptable, between .60 and .80, "

    • "The dependent variable is operationalized in line with earlier research (Harteveld et al., 2013; Lubbers, 2008) which makes it unlikely to underlie the null finding. Personality traits were measured using the 20-item mini-IPIP which is a reliable and valid instrument of the Big Five traits (Donnellan et al., 2006). Future research could turn to more elaborate personality inventories in order to explore associations between trust in EU institutions and the sub-dimensions of Agreeableness (Osborne et al., 2013).

    ABSTRACT: We still do not fully understand why attitudes toward the European Union differ among citizens. In this study, we turn to the Big Five personality traits: Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism as antecedents of European Union attitudes. In a national survey, we focus on attitudes toward widening and deepening of the European Union, trust in European Union institutions, identification with the European Union and negative affect experienced toward the European Union. We theorize that the Big Five traits are heterogeneously associated with the different European Union attitudes. We confirm that the Big Five traits are indeed associated with some but not all European Union attitudes. Accordingly, personality is expected to shape how citizens' respond to changes in the institutional setup of the European Union.
