This study aimed at testing the dimensionality of the Need for Cognition Scale (NCS-18), controlling the effect of negative items. Participants were 215 undergraduate students from João Pessoa (PB) with mean age of 20 years (SD = 3.79). They answered the NCS-18 and demographic questions. Three models were tested: M1 (conventional one-factor model), M2 (two-factor, with positive and negative items loading in separate factors), and M3 (one-factor model, controlling for the effect of negative items). Results showed that M2 and M3 models had better fi t indexes compared to M1. Nevertheless, M3 also had better fi t indexes than M2. In conclusion, evidence that the NCS-18 is more adequately represented by one-factor model was observed, especially when the effect of negative items is controlled. [ABSTRACT FROM AUTHOR]

Even the Implicit Association Test (IAT) has been shown to be relevant in measuring various psycho-logical constructs there are few studies considering it in Brazil. This paper aims to introduce a free program (FreeIAT) to perform IAT, illustrating it with a measure of attitudes toward polyamory. Participants were 50 undergraduate students with mean age of 22 years (62% women) who answered an explicit scale attitude toward polyamory and the Monogamy-Polyamory IAT. Results showed a negative correlation between implicit (latency of incongruent block) and explicit attitudes measures toward polyamory, indicating that the greater the acceptance of polyamory, the lesser time to asso-ciation between the stimuli (positive words and polyamory). There was no correlation between the D Score and the explicit attitudes toward polyamory, suggesting that people in favor of polyamory are not necessarily opposed to monogamy. In conclusion, the FreeIAT shows a streamlined inter-face, following the variations of the classic IAT and allowing collective application. Moreover, the fact of being a free program with open source it has the potential to encourage research on implicit measures in Lusophone cultures. [ABSTRACT FROM AUTHOR]

Introduction: The study of work engagement is key for better understanding the underlying mechanisms that lead people to feel more motivated at work. The construct has gained prominence over recent decades, and the Utrecht Work Engagement Scale (UWES) has emerged as the most popular tool to assess the construct. Though widely known and used, more psychometric evidence is needed for the UWES, especially its item parameters. Method: This study (N = 525) aimed to provide psychometric evidence for the UWES and its shortened versions in Brazil, using a range of robust statistical analyses (e.g., Confirmatory Factor Analysis, Item Response Theory). Results: Results reveal good model fit and high internal consistency for both unidimensional and three-dimensional UWES structures. UWES items also showed high discrimination, difficulty, and information levels. Finally, significant correlations between UWES and workaholism and job satisfaction provided evidence of the convergent validity of the UWES in Brazil. Conclusion: This study's findings broaden the understanding of work engagement and underscore the utility of the UWES as an efficacious tool for measuring work engagement in Brazil, paving the way for effective interventions and policies in diverse workplace environments.
