Extant research addressing how consumers respond to electronic word-of-mouth (eWOM) remains limited. Even less attention has been devoted to examining the trustworthiness of consumer reviewers with different ethnic backgrounds. The purpose of this paper is to explore the influence of reviewer ethnicity, review valence and social distance (to three different ethnic groups) on perceived reviewer trustworthiness, brand attitude and purchase intention toward a product evaluated by reviewers of three ethnic backgrounds. The study adopted a 2 (review valence)×3 (reviewer ethnicity) design; 398 participants were randomly assigned to one of the six conditions. A mock product-review web page for each study condition was created to manipulate review valence and reviewer ethnicity. Results show that while review valence, reviewer ethnicity and social distance each had a significant effect on perceived reviewer trustworthiness, only review valence had an influence on brand attitude and purchase intention. The interaction between reviewer ethnicity and review valence also had a significant effect on perceived reviewer trustworthiness, brand attitude and purchase intention. The current study is the first to apply social distance theory to explain cross-cultural perception of trust, as it extends and updates the original social distance scale to broaden its empirical relevance to contemporary society via an eWOM marketing context. As social distance is a fluid and timely concept to study the diverse ethnic cultural environment, the current findings carry strong implications to future research in a wide variety of digital communication and marketing contexts, among others.

The threat of a potential H1N1 pandemic was first reported in April 2009. Unlike the regular seasonal influenza that affects primarily preschool children, pregnant women, and the elderly, young, healthy adults were identified as 1 of the high-risk groups for contracting the H1N1 virus. This study was among the first to explore the impact of influenza communication on college students’ pandemic risk perception and vaccination intent. Study results suggest that news media dependency and risk perception have a positive influence on college students’ vaccination intent.

The sustainable consumption trend is gaining popularity among Gen Z. Guided by the environmental awareness construct, Norm Activation Model, corporate social responsibility paradigm, and shopping value perspective, this study aims to assess how environmental awareness is connected to consumer evaluations of their personal consumption behavior and corporate social responsibility to help explain their sustainable apparel purchase intention, in conjunction with consumer shopping motivation. An online survey was conducted with a group of Gen Z consumers (N = 192). The results from testing the conceptual model indicated that environmental awareness was positively linked to personal norms and CSR expectations, both of which were similarly related to green purchase intentions. While hedonic and utilitarian shopping value was positively associated with CSR expectations, they were both negative predictors of green purchase intentions. This study is the first to integrate environmental ethics, personal ethics, expectations of corporate ethics, and hedonic vs. utilitarian consumption value to better understand the attitude–behavior gap in sustainable apparel purchase decision-making.

Failure to adhere to an antihypertensive regimen and interactions between antihypertensives and other medicines represent serious health threats to older adults. This study tested the usability of a touch-screen-enabled personal education program (PEP). Findings showed that older adults rated the PEP system usability, system usefulness, and system-use satisfaction at a moderately high level for prototype-1 and at an exceptionally high level for prototype-2. A 201.91% reduction in interface errors and a 31.08% decrease in interface time also were found between the two trials. This participatory usability design was highly successful in tailoring its program interface design to accommodate older users to enhance their health communication and technology use efficacy.

Consumption of single-use bottled water has created severe environmental pollution problems around the world. By incorporating the theory of planned behavior with the additional cognitive and behavioral factors of perception, prior behavior, and knowledge variables, this study examined college students’ bottled water consumption intentions. Results show that perceived peer norm, behavioral control, and perceived bottled water benefits are significantly related to purchase intentions, as are prior levels of bottled water and tap water consumption. The same is not true for attitude toward and knowledge of bottled water consumption. Perceived tap water benefits negatively moderated the attitude-purchase intention relationship, whereas prior bottled water consumption negatively moderated the behavioral control-purchase intention link.
