Objective: The field of food addiction has attracted growing research attention. The modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) is a screening tool based on DSM-5 criteria for substance use disorders. However, there is no validated instrument to assess food addiction. Methods: The mYFAS 2.0 has been transculturally adapted to Brazilian Portuguese. The data for this study was obtained through an anonymous web-based research platform: participants provided sociodemographic data and answered Brazilian versions of the the mYFAS 2.0 and the Barratt Impulsivity Scale (BIS-11). Analysis included an assessment of the Brazilian mYFAS 2.0’s internal consistency reliability, factor structure, and convergent validity in relation to BIS-11 scores. Results: Overall, 7,639 participants were included (71.3% females; age: 27.2±7.9 years). The Brazilian mYFAS 2.0 had adequate internal consistency reliability (Cronbach’s alpha = 0.89). A single factor solution yielded the best goodness-of-fit parameters for both the continuous and categorical version of the mYFAS 2.0 in confirmatory factor analysis. In addition, mYFAS 2.0 correlated with BIS-11 total scores (Spearman’s rho = 0.26, p < 0.001) and subscores. Conclusion: The Brazilian mYFAS 2.0 demonstrated adequate psychometric properties in our sample; however, future studies should further evaluate its discriminant validity.

The paper intends to analyze how the new forms of interaction and engagement allowed by the interactive and participative online technologies can help to foster empowering civic practices. It develops a theoretical reflection on the potential intersections areas between audiences, thought as the “persona ficta” (Dayan, 2005) that emerges in the role of enacting attention towards an external performance, and the public, thought as a collective entity that calls external attention and contains a fundamental orientation to shared and consensual action. It will be argued that in order to analyze the co-presence and potential overlapping between these two collectivities, it is necessary to adopt the concepts of “mediation” (Silverstone, 1999) and “civic cultures” (Dahlgren, 2009). The paper will develop this hypothesis though the empirical analysis of a case study focused on Beppegrillo.it, an Italian weblog acting as a communicative platform for the development of a civic and political movement.

Este artigo procura estudar o modo como as novas formas de interação e de envolvimento colocadas à disposição pelas tecnologias online interativas e participativas poderão ajudar a incentivar o empoderamento das práticas cívicas. Este trabalho enforma uma reflexão teórica sobre as potenciais áreas de interseção entre as audiências, enquanto "persona ficta" (Dayan, 2005) que emerge no papel de encenar a atenção face a uma performance externa, e o público, considerado enquanto entidade coletiva que chama a atenção externa, e que inclui uma orientação fundamental relativamente à ação partilhada e consensual. Defendemos que, para analisar a co-presença e a potencial sobreposição entre estas duas coletividades, é necessário adotar os conceitos de "mediação" (Silverstone, 1999) e de "culturas cívicas" (Dahlgren, 2009). O artigo desenvolve esta hipótese através da análise empírica de um estudo de caso focado em Beppegrillo.it, um weblog italiano que funciona como uma plataforma de comunicação para o desenvolvimento de um movimento cívico e político.
