Since its introduction, the Rosenberg General Self-esteem scale (RGSE, Rosenberg, 1965) has been one of the most widely used measures of global self-esteem. We conducted four studies to investigate (a) the goodness of fit of a bifactor model positing a general self-esteem factor (GSE) and two specific factors grouping positive (MFP) and negative items (MFN), and (b) different kinds of validity of the GSE, MFN and MFP factors of the RSGE. In the first study (n= 11,028), the fit of the bifactor model was compared with those of nine alternative models proposed in literature for the RGSE. In Study 2 (n = 357), the external validities of GSE, MFP and MFN were evaluated using objective grade point average data and multi-method measures of prosociality, aggression, and depression. In Study 3 (n = 565), the across-rater robustness of the bifactor model was evaluated. In Study 4, measurement invariance of the RGSE was further supported across samples in three European countries, Serbia (n= 1,010), Poland (n= 699), and Italy (n= 707), and in the United States (n = 1,192). All in all, psychometric findings corroborate the value and the robustness of the bifactor structure and its substantive interpretation. Keywords.

3Self-esteem reflects an overall subjective evaluation of personal worth (Marsh & O'Mara, 2008;Rosenberg, 1965). A considerable amount of research has investigated the nature of this construct (Baumeister, Campbell, Krueger, &Vohs, 2003), which represents one of the most popular individual differences constructs in psychology (see Donnellan, Trzesniewski, & Robins, 2011, for a review). Self-esteem, similar to any other psychological construct, is a latent variable that is not directly observable. Yet individuals' standing on the latent attribute can be inferred through their answers to statements intended to describe internal positive and negative states, such as feelings and emotions about the self (Borsboom, Mellenbergh& van Heerden, 2003).Since its introduction, the Rosenberg General Self-esteem scale (RGSE;Rosenberg, 1965) has been one of the most popular and widely used measures of global self-esteem (Blascovich &Tomaka, 1991;Donnellan et al., 2011;Schmitt &Allik, 2005).According to PsycInfo, the instrument has been cited 3,016 times during the last five years (2010)(2011)(2012)(2013)(2014).The scale assesses the "feeling that one is good enough" (Rosenberg, 1965, p. 31), and consists of 10 items with a high degree of face validity. A large body of empirical evidence supports the internal consistency of the instrument (Byrne, 1983), its predictive validity (Kaplan, 1980), and its equivalence over time (Marsh, Scalas, &Nagengast, 2010;Motl & DiStefano, 2002). The popularity of the 10-item RGSE has been due in part to its long history of use, its uncomplicated language, and its brevity (it takes only 1 or 2 minutes to be completed).In addition to its privileged place in the literature, the RGSE offers other...
