An Empirical Investigation of the Equity of Health Promotion: The Role of Message Source and Content

Good communication capability is crucial for the effectiveness of health promotion. This study aims to examine the relationship between message source (expertise and attractiveness) and content (informativeness and entertainment) on the equity of health promotion. The empirical data were collected through a survey in Tangerang, Indonesia. The number of samples were 178 respondents. Multiple regressions analysis was performed to test the conceptual model and the proposed hypotheses. The findings showed that the equity of health promotion was influenced by expertise, attractiveness, and entertainment, while informativeness did not affect the equity of health promotion significantly.

Understanding the Adoption of Incentivized Word-of-Mouth in the Online Environment

Nowadays, word-of-mouth is a very important component of e-commerce activity because consumers are very sensitive to other people’s opinions. Depending on the companies’ politics, these opinions can be incentivized or non-incentivized. One of the major dilemmas consists in establishing which kind of word-of-mouth has more influence on customers’ perceptions. The purpose of this study is to assess the relationships between perceived argument quality (PAQ) and perceived source expertise (PSE), on the one hand, and electronic word-of-mouth adoption intention on the other hand, for an incentivized message compared to a non-incentivized message. We processed answers from two different random groups by using adapted PAQ and PSE inventories of questions. The constructs, latent variables and items were analyzed in IBM Amos software, and our findings confirm the hypotheses regarding the relationship between the attributes of the message (argument quality and source expertise) and message credibility. Additionally, we found a significant positive relationship between message credibility and electronic word-of-mouth adoption intention. Our research also explores the moderating role of the message type (incentivized vs. non-incentivized) in the relationships above, and we discovered that the message type significantly moderates the relationship between perceived argument quality and credibility, but the type of message does not moderate the relationship between message credibility and eWOM adoption intention.

Can You Believe it? An Investigation into the Impact of Retraction Source Credibility on the Continued Influence Effect

The continued influence effect refers to the finding that people often continue to rely on misinformation in their reasoning even if the information has been retracted. The present study aimed to investigate the extent to which the effectiveness of a retraction is determined by its credibility. In particular, we aimed to scrutinize previous findings suggesting that perceived trustworthiness but not perceived expertise of the retraction source determines a retraction’s effectiveness, and that continued influence arises only if a retraction is not believed. In two experiments, we found that indeed source trustworthiness but not source expertise influences retraction effectiveness, with retractions from low-trustworthiness sources entirely ineffective. We also found that retraction belief is indeed a predictor of continued reliance on misinformation, but that substantial continued influence effects can still occur with retractions designed to be and rated as highly credible.

Expert cues: how expert reviewers are perceived online

PurposeThe purpose of this paper is to explore different types of source expertise and how they influence perceived message quality. Consumers face the challenge to identify valuable online reviews. Source expertise as a signal of message quality can be displayed differently, depending on website layout, operator and review author.Design/methodology/approachTwo scenario-based experiments were conducted questioning 135 and 275 participants. They investigate the effect of different types of expert reviewers on perceived message quality and also examine the interplay of source expertise and source trustworthiness.FindingsThe findings reveal that the different types of expert reviewers differ in perceived expertise and their impact on perceived message quality. Claims of expertise induce the highest perceived expertise compared to the other expert types and non-experts, but are perceived as less trustworthy.Research limitations/implicationsFuture research should examine the influence of the expert types across different product and service categories and could also include moderating influences that reflect how consumers process expert cues differently.Practical implicationsCues that signal high expertise and high trustworthiness are likely to deliver the most valuable online reviews. This should be incorporated in the website's layout to help consumers find valuable information.Originality/valueThe approach of this research is novel in that it undertakes comparisons between three types of expert cues and non-experts. It also addresses the interplay of source expertise and trustworthiness and examines the effect on message quality.

Court Case Context and Fluency-Promoting Photos Inflate the Credibility of Forensic Science

Faulty forensic science sometimes makes its way into the courtroom where jurors must evaluate its credibility. But at least two factors may inflate how credible jurors find claims about forensic science: the mere context of a court case and the cognitive fluency of the evidence. To investigate, we asked people to judge various claims about forensic science as true or false. In Experiment 1 ( N = 287), we manipulated court case context by either attributing the claims to an expert in court or not specifying their origin. In Experiment 2 ( N = 320), we manipulated courtroom setting orthogonal to source expertise. In both, we manipulated fluency via the presence of related but nonprobative photos. We found each factor increased people’s bias to judge forensic science claims true. Our findings suggest the justice system must improve the quality of forensic science upstream from the courtroom to ensure jurors’ credulity is warranted.

YouTube channels influence on destination visit intentions

Purpose With the usage of social media and Web 2. 0, YouTube channels currently play a pivotal role in supporting a traveler’s destination visit. Travelers create their YouTube channels and share their past experiences in the form of videos, which helps other potential travelers to support their destination visit. The purpose of this paper is to understand how travelers adopt information through YouTube channels and how it influences the traveler’s intention to visit a destination. Design/methodology/approach A research model was constructed and empirically tested by using a sample of 486 respondents who watch YouTube channels before visiting a destination. Further, the hypotheses of this study were validated with the help of structural equation modeling using partial least squares. The respondents in this study were from Delhi. Findings This paper found comprehensiveness, relevance, timeliness, source expertise and attitude as the most significant predictors of a traveler’s destination visit intention through YouTube channel adoption. Further, source trustworthiness and accuracy were not found to be statistically significant. Research limitations/Implications The findings of this paper were based on data taken from the local respondents in Delhi. Further, it analyzed the influence of only seven dimensions on destination visit intention, which could have excluded some important factors that influence tourists’ destination visit intention. Practical implications This paper has provided implications for YouTube vloggers and tourists. The result proves that while making decisions regarding destination visit, tourists thinks critically and scrutinize the content of YouTube channels prior to deciding a destination. So, vloggers should provide relevant, comprehensive and accurate destination information through their videos to tourists. Originality To the best of authors’ knowledge, this paper is the first in the Indian context to examine the adoption of YouTube channels before visiting destinations through information adoption models with additional constructs.
