“…Whereas, Wu (2013) conclude that the negativity bias documented in the psychology literature may not be applicable to the context of eWOM. Scholars advanced that product type may moderate the relationship between review valence and attitudinal as well as behavioral outcomes (e.g., Cui et al, 2011; Filieri et al, 2018; Ketron, 2017; Mudambi & Schuff, 2010; Sen & Lerman, 2007).…”

“…Several studies have analyzed the eWOM valence and its impact on business performance and consumer behavior. For instance, scholars investigated the impact of review valence on sales (e.g., Chevalier & Mayzlin, 2006), business performance (Raguseo & Vitari, 2017), message persuasiveness (Kostyra et al, 2016; Lee & Koo, 2012; Lee et al, 2008; Park et al, 2007; Park & Lee, 2008; Tsao et al, 2015; Zhang et al, 2010), purchase intention (Filieri, 2016; Ketron, 2017), and review helpfulness (e.g., Agnihotri & Bhattacharya, 2016; Filieri, 2015; Filieri et al, 2019; Mudambi & Schuff, 2010; Pan & Zhang, 2011; Park & Nicolau, 2015).…”

“…Product type is important in understanding the influence of review valence on consumer attitudes and behavior (Filieri et al, 2018; Lee & Shin, 2014; Mudambi & Schuff, 2010; Pan & Chiou, 2011; Park & Lee, 2009; Purnawirawan et al, 2015; Sen & Lerman, 2007; Zhu & Zhang, 2010). Research has investigated the influence of online reviews valence for different types of products such as: experience versus search (e.g., Ketron, 2017; Park & Lee, 2009); experience versus credence (Pan & Chiou, 2011); hedonic versus utilitarian (e.g., Sen & Lerman, 2007); and more popular versus less popular products (Zhu & Zhang, 2010).…”

“…Research demonstrated the influence of review valence on consumers' purchase intention and preferences (Filieri, 2016; Ketron, 2017; Kostyra et al, 2016; Lee & Koo, 2012; Lee et al, 2008; Lee & Shin, 2014; Lin & Xu, 2017; Mauri & Minazzi, 2013; Park et al, 2007; Park & Lee, 2008; Purnawirawan et al, 2015; Tsao et al, 2015). Based on schema congruity theory (Mandler & Parker, 1976), the impact of the stimulus‐based schema (i.e., review valence) on behavior will be higher depending on the degree of incongruity with mental‐based schema; that is, negative reviews of products perceived as not harmful for the environment will be more impactful on consumer intention than negative reviews of products generally perceived as harmful for the environment.…”

“…However, contrasting results have also been produced in different studies about the role of positive and negative reviews on review helpfulness, consumer attitude, and behavior (Gershoff et al, 2003; Lin & Xu, 2017; Mudambi & Schuff, 2010; Wu, 2013; Zhang et al, 2010). To explain these contrasting results, scholars have investigated the moderating role of product type in the relationship between review valence and behavioral outcomes (e.g., Chua & Banerjee, 2016; Filieri et al, 2020; Ketron, 2017; Lee & Shin, 2014; Mudambi & Schuff, 2010; Pan & Chiou, 2011; Park & Lee, 2009; Sen & Lerman, 2007; Zhu & Zhang, 2010). These studies proved that product type moderates the influence of positively as well as negatively valenced reviews (e.g., Cui et al, 2011; Mudambi & Schuff, 2010).…”

Consumers are increasingly interested to know about the environmental impact (EI) of products and, at the same time, they form attitudes after reading online consumer reviews. Drawing on negativity bias, schema congruity theory, and norm‐activation model, we investigate the effects of environmentally framed electronic word‐of‐mouth messages of different valence, on perceived review usefulness, product attitude and purchase intention in products with low versus high EI. Two factorial experiments (positive vs. negative reviews; low vs. high EI) were conducted respectively with a sample of 321 Italian and 250 French consumers. The findings of the two studies show a partial support of the moderating role of product EI, suggesting that products perceived to have a high impact on the environment strengthen the impact of a positive or a negative review carrying environmental messages. The effect of a positive and a negative review is contingent upon the level of consumers' environmental concern. Negative reviews of high impact products are more impactful in contexts in which environmental concerns are high, while positive reviews are more significant when environmental concerns are low. The perceived usefulness of a negative review about high impact products influences consumers' attitude and purchase intention when moral norms are high.

With the development of Internet and e-commerce, traditional word of mouth communications have evolved into electronic word of mouth (eWOM) communications, which significantly affect consumers in their decision-making process. Previous studies investigated how consumers process information online and how it affects consumer behaviour applying the Elaboration Likelihood Model (ELM). ELM distinguishes between two routes of information processing: central and peripheral. Existing literature has a mixed of findings regarding factors affecting information process using ELM and lacking a comprehensive review providing evaluation and a consolidated view of these factors. Thus, the aim of this research is to evaluate the use of ELM in the context of eWOM research by performing a systematic review and weight analysis of existing research findings. This will help consolidating the predictive power of the independent variables on the dependent variable, by taking into consideration the number of times a relationship has been previously examined. The model developed through weight analysis would allow eWOM practitioners to decipher more influential factors.
