Resumo Este estudo teve como objetivo validar para o contexto brasileiro uma escala de cocriação de valor direcionada para o turismo (Busser & Shulga, 2018) e também mensurar os seus efeitos em relação à intenção de recomendação boca-a-boca (WoM). Os procedimentos metodológicos adotados incluíram tradução da escala original, validação de face, adaptações ao objeto de pesquisa e análise de dados por meio de modelagem de equações estruturais (MEE). A amostra compreendeu 210 turistas que vivenciaram experiências de turismo nos últimos 02 anos. O instrumento de coleta de dados foi feito pela plataforma Google Forms e submetido aos respondentes no segundo semestre de 2018. Entre os resultados: a) Todas as 5 dimensões da escala original foram suportadas nesta pesquisa (significância, colaboração, contribuição, reconhecimento e resposta afetiva) e b) a escala apresentou um R² de 0,611, explicando 61% da intenção de recomendação boca-a-boca.

Abstract This study aimed to validate for the Brazilian context a value co-creation scale directed towards tourism (Busser & Shulga, 2018) and also to measure its effects in relation to the intention of word-of-mouth recommendation. The methodological procedures adopted included translation of the original scale, face validation, adaptations to the research object and data analysis through structural equation modeling (SEM). The sample comprised 210 tourists who have experienced tourism experiences in the last 02 years. The data collection instrument was made using the Google Forms platform and submitted to respondents in the second half of 2018. Among the results: a) All 5 dimensions of the original scale were supported in this research (significance, collaboration, contribution, recognition and affective response) and b) the scale presented an R² of 0.614, explaining 61% of the intention of mouth-to-mouth recommendation.

Electronic word-of-mouth (eWOM), known as online recommendations or reviews, arouses academic interest, mainly due to increased use of the Internet and online shopping (Sparks & Browning, 2011). Even with the growth of academic research on online behavior, there is still a constant questioning regarding the main factors related to eWOM and that influence the online users' purchase intention (Ladhari & Michaud, 2015), with emphasis on the effect of the credibility of the source in the attitude with eWOM (Cheung, Lee & Rabjohn, 2008). Therefore, the main purpose of this article is to identify, through a mapping of current knowledge, the main gaps and trends for future research on the subject. The results point to a growing trend of research related to quality and perceived credibility, to the involvement, identification and persuasion of users, among other suggestions.

El boca a boca electrónico (electronic word-of-mouth: eWOM), conocido como recomendaciones o revisiones online, despierta interés académico, principalmente debido al aumento en el uso de internet y de las compras online (Sparks & Browning, 2011). Aún ante el crecimiento de las investigaciones académicas sobre el comportamiento online, existe un cuestionamiento constante referente a los principales factores relacionados al eWOM, que influyen en la intención de compra de los usuarios online (Ladhari & Michaud, 2015), destacando la actuación del efecto de la credibilidad de la fuente en la actitud con el eWOM (Cheung, Lee & Rabjohn, 2008). Así, el propósito central de este artículo es identificar, por medio de un mapeo del conocimiento actual, cuáles serían los principales vacíos existentes y las tendencias para investigaciones futuras sobre el tema. Los resultados indican una creciente tendencia de investigaciones relacionadas con la calidad y credibilidad percibida, y el involucramiento, identificación y persuasión de los usuarios, entre otras sugerencias.

Abstract Purpose Celebrity endorsement is a phenomenon widely used by companies and studied by researchers. Despite the generally positive aspects of endorsement on the evaluation of products, in some cases, celebrities cannot substantially help promote products. The purpose of this paper is to analyze the effectiveness of celebrity endorsement effect in an aspiring new celebrity. Design/methodology/approach Four studies involving 664 respondents were conducted to analyze the effectiveness of the endorsement. In addition to verifying the existence of the effect (Study 1), studies were conducted focusing on contextual variables with the potential to modify effect. Study 2 analyzes the brand and charisma effects, Study 3 analyzes the congruence between celebrities and Study 4 analyzes the exposure level of the endorser celebrity. Findings The results demonstrate the effectiveness of this celebrity endorsement, as well as the effect of different contexts on endorsement, demonstrating that although new celebrities are less affected by acclaimed celebrities, as they become better known, to use the endorsement of celebrities with charisma and who relating in some way to the aspiring celebrity, can be an effective strategy, especially for the beginners in the career. Originality/value This research contributes to the knowledge of celebrity endorsement to fill the lack pointed out in previous studies in the field over the effectiveness of this effect and, above all, the moderator variables that can influence or even annul this effect. In addition, by developing its own image and reputation, the aspiring new celebrity receives less influence from the endorser.
