Playing the central role in this relational process, consumer or customer engagement (used interchangeably in this context), emerged as one of the main constructs explaining the success and failure of brands on social media. Considering engagement as a multidimensional construct composed of cognitive, emotional and behavioral dimensions that varies according to the subject (e.g., customer or employee), focal object (e.g., brand, product or advertising), and context (e.g., retail or online), in this dissertation we make a specific field cutting in order to discuss consumer engagement (subject) with brands (object in Article 2 and 3) or brand communities (object in Article 1) on social media (context). As a general aim of the dissertation, we analyze consumer engagement in different nomological networks, prioritizing its antecedents and mediating role (Article 1) or consequences and its relationship with another measure of engagement (Article 3), in addition to perform a comparative analysis of different scales developed to measure it (Article 2). In the Article 1, we show that the Vivek, Beatty, Dalela, and Morgan (2014) consumer engagement scale, originally developed for application in multiple contexts, can also be applied to multiple objects. We validate this scale in a nomological network with perceived homophily and brand involvement as antecedents and corporate reputation as consequence. Our results show that besides having a direct positive effect on corporate reputation, consumer engagement has a strong mediating role. In the Article 2, our goal is to compare some of the main scales developed to measure consumer engagement: Dessart, Veloutsou, and Morgan-Thomas (2016), Hollebeek, Glynn, and Brodie (2014) and Vivek et al. (2014). To do this, we propose a procedure for the comparative analysis of scales that involves i) the selection, ii) standardization and iii) analysis of measures. We replicate three selected scales with the same object (brand) and context (social media), considering that most of the developed scales were applied to the same object and context. Based on the Classical Test Theory (CTT) and Item Response Theory (IRT) analysis, our results show similarities, differences, and advantages of applying each scale. In Article 3 we jointly analyze two streams of consumer engagement studies by considering brand engagement in self-concept (BESC) as a measure of engagement with brands in general (Sprott, Czellar, & Spangenberg, 2009) and consumer engagement with a specific brand Vivek et al., 2014), and how the latter impacts the perceived value of consumers and corporate reputation. By means of the multigroup analysis with samplings carried out in Brazil and the United States, our results showed that in addition to excellent adjustment, both at the model level and at the path level there was no difference between the groups, which indicates the cross-cultural invariance in the structural model. Finally, in Chapter 5 we synthesize the conclusions of the dissertation. / Pesquisa acadêmicas sugerem que as mídias sociais podem melhorar a sua reputação corporativa, vendas, retorno sobre o investimento, boca-a-boca positivo e criar valor para os consumidores. Desempenhando o papel central neste processo relacional, o engajamento do consumidor ou cliente (usados como sinônimos neste contexto), emergiu como um dos principais construtos que explicam o sucesso ou fracasso de marcas nas mídias sociais. Considerando o engajamento como um construto multidimensional composto por dimensões cognitiva, afetiva e comportamental que varia de acordo com o sujeito (ex. consumidor ou empregado), objeto focal (ex. marca, produto ou propaganda) e contexto (ex. varejo ou online), nesta tese nós fazemos um corte mais específico do campo e para discutir o engajamento do consumidor (sujeito) com marcas (objeto no Artigo 2 e 3) ou com a comunidade de marca (objeto no Artigo 1) em mídias sociais (contexto). Como objetivo geral da tese, nós analisamos o engajamento do consumidor em diferentes redes nomológicas, priorizando seus antecedentes e papel mediador (Artigo 1), ou consequentes e sua relação com outra medida de engajamento (Artigo 3), além de realizar uma análise comparativa de diferentes escalas desenvolvidas para medi-lo (Artigo 2). No Artigo 1, nós mostramos que a escala de engajamento do consumidor da Vivek, Beatty, Dalela e Morgan (2014), originalmente desenvolvida para aplicação em múltiplos contextos, também pode ser aplicado a múltiplos objetos. Nós validamos esta escala em uma rede nomológica com homofilia percebida e envolvimento com marca como antecedentes e reputação corporativa como consequente. Nossos resultados mostram que além de ter efeito positivo direto na reputação corporativa, o engajamento do consumidor tem um forte papel mediador. No Artigo 2, o nosso objetivo é comparar algumas das principais escalas desenvolvidas para medir o engajamento do consumidor: Dessart, Veloutsou e Morgan-Thomas (2016), Hollebeek, Glynn e Brodie (2014) e Vivek et al. (2014). Para fazer isso, nós propomos um procedimento para análise comparativa de escalas que envolve i) a seleção, ii) padronização e iii) análise das medidas. Nós replicamos três escalas selecionadas com um mesmo objeto (marca) e contexto (social media), considerando que a maioria das escalas desenvolvidas foram aplicadas para este mesmo objeto e contexto. Baseado nas análises da Teoria Clássica dos Testes (TCT) e na Teoria de Resposta ao Item (TRI), nossos resultados mostram similaridades, diferenças e vantagens da aplicação de cada escala. No Artigo 3 nós analisamos conjuntamente duas correntes de estudo do engajamento do consumidor ao considerar engajamento com marca no autoconceito (BESC) como uma medida de engajamento com marcas em geral (Sprott, Czellar, & Spangenberg, 2009) e engajamento do consumidor com uma marca específica (Vivek et al., 2014), e como o último impacta no valor percebido dos consumidores e na reputação corporativa. Por meio da análise multigrupo com amostragens realizadas no Brasil e Estados Unidos, nossos resultados mostraram que além de excelente ajuste, tanto no nível do modelo como no nível de caminho não houve diferença entre os grupos, o que indica a invariância intercultural dos grupos no modelo estrutural. Por fim, no Capítulo 5 nós sintetizamos as conclusões da dissertação.

The use of online brand communities and its effect on brand loyalty has been heavily researched in previous studies. However, online brand communities in the context of motorsport, which is inherently different from other sports, has not been thoroughly researched previously and currently remains unknown. The study aims to understand how motorsport followers become brand loyal within their brand communities and if their identification with the brand has an influence on the process. The following research questions were developed to find these answers: RQ1: "How does involvement in online brand communities affect brand loyalty among motorsport fans?" RQ2: "How do online brand communities influence brand identification for motorsport enthusiasts?" RQ3: "How does member participation in online brand communities contribute to the connection between online brand communities and brand loyalty in motorsport?" A quantitative research design was followed, using a survey with questions developed based on previous research. The final sample size was 403 after the data was cleaned. The findings from the survey suggest that concepts such as brand community engagement had a direct effect on the development of brand loyalty. Other findings also showed that brand identification had a mediating role between certain brand community belonging characteristics and brand loyalty. Additionally, the study found that brand community participation had no moderating effect between brand community belonging characteristics and brand loyalty, however did have a direct link between brand identification and brand loyalty. Further research includes testing the study’s model in other brand communities within the motorsport context to provide more information into this unknown field of sport and its members. / Användningen av online varumärkesgemenskaper och dess effekt på varumärkeslojalitet har undersökts noggrant i tidigare studier. Online varumärkesgemenskaper inom motorsport, som är fundamentalt annorlunda från andra sporter, har dock inte tidigare undersökts ingående och är för närvarande okända. Studien syftar till att förstå hur motorsportföljare blir varumärkeslojala inom sina varumärkesgemenskaper och om deras identifiering med varumärket har inflytande i processen. Följande forskningsfrågor utvecklades för att hitta dessa svar: FF1: "Hur påverkar deltagande i online varumärkesgemenskaper varumärkeslojalitet bland motorsportfans?" FF2: "Hur påverkar online varumärkesgemenskaper varumärkesidentifiering för motorsportentusiaster?" FF3: "Hur bidrar medlemsdeltagande i online varumärkesgemenskaper till kopplingen mellan online varumärkesgemenskaper och varumärkeslojalitet inom motorsport?" En kvantitativ forskningsdesign följdes med hjälp av en enkät med frågor utvecklade utifrån tidigare forskning. Den slutliga provstorleken efter att data rengjorts var 403. Resultaten från undersökningen tyder på att begrepp som engagemang i varumärkesgemenskap hade en direkt effekt på utvecklingen av varumärkeslojalitet. Andra resultat visade också att varumärkesidentifiering hade en medierande roll mellan vissa egenskaper för varumärkesgemenskap och varumärkeslojalitet. Dessutom visade studien att deltagande i varumärkesgemenskap inte hade en modererande effekt mellan egenskaper för varumärkesgemenskap och varumärkeslojalitet, men hade en direkt länk mellan varumärkesidentifiering och varumärkeslojalitet. Vidare forskning inkluderar att testa studiemodellen i andra varumärkesgemenskaper inom motorsportkontexten för att tillhandahålla mer information om denna okända sport och dess medlemmar.
