Purpose: Many Internet users search for health information but they struggle with assessing the quality of the information they find. By drawing on a multi-modal approach to data collection, this study aims to understand further the nuanced cognitive processes that people utilize as they acquire and evaluate online health information.

Design: We used a mixed-methods approach that includes surveys, interviews, and observations of 76 diverse adults of all ages in the Chicago area completing various health information-seeking tasks.

Findings: Most participants begin their information-seeking process on search engines. We identified the most popular credibility-assessment strategies used on the search engine results’ pages (SERP) as well as on websites. We also explored how the process of executing such strategies reveals greater and lesser savvy among users.

Research Limitations: While the sample size and methods limit its generalizability, this study included a larger and more diverse group of participants than most observational work, which results in data about a wider range of behaviors than is typical of such research.

Social Implications: Our findings showed that most of our participants could use additional education regarding credibility assessment of online health information. Additionally, since a great deal of credibility assessment occurs on SERP, search companies bear a particular responsibility for ensuring the quality of the information their results highlight.

This study aims to investigate the relationships among corporate-brand credibility, product-brand personality, and purchase intention, specifically in China's auto industry. A large-scale survey was conducted in four major Chinese Mainland cities: Beijing, Shanghai, Guangzhou, and Chengdu. A total of 800 questionnaires were distributed for the study. Ultimately, 477 usable cases were collected for a 60 percent response rate. Results reveal that corporate-brand credibility and product-brand personality have direct positive effects on purchase intention. Furthermore, corporate-brand credibility acts as a positive moderator in the relationship between product-brand personality and purchase intention. This chapter offers new theoretical insights into the influential factors affecting consumers' purchase intentions by testing the moderating effect of corporate-brand credibility in the relationship between product-brand personality and purchase intention. It further provides useful suggestions to companies on brand credibility and personality issues.

This study aims to address the growing importance of online health information (OHI) and the associated uncertainty. Although previous research has explored factors influencing the credibility of OHI, results have been inconsistent. Therefore, this study aims to identify the essential factors that influence the perceived credibility of OHI by conducting a meta-analysis of articles published from 2010 to 2022. The study also aims to examine the moderating effects of demographic characteristics, study design and the platforms where health information is located.

Based on the Prominence-Interpretation Theory (PIT), a meta-analysis of 25 empirical studies was conducted to explore 12 factors related to information content and source, social interaction, individual and media affordance. Moderators such as age, education level, gender of participants, sample size, platforms and research design were also examined.

Results suggest that all factors, except social support, have significant effects on the credibility of OHI. Among them, argument quality had the strongest correlation with credibility and individual factors were also found to be relevant. Moderating effects indicate that social support was significantly moderated by age and education level. Different sample sizes may lead to variations in the role of social endorsement, while personal involvement was moderated by sample size, platform and study design.

This study enriches the application of PIT in the health domain and provides guidance for scholars to expand the scope of research on factors influencing OHI credibility.

This paper is based on the conviction that school principal leadership varies considerably in accordance with the level of credibility they develop with the groups with which they interact. To become better leaders, school principals must adopt a proactive approach and develop the means of consolidating their credibility. Readers will understand that school principals have potential levers at their disposal, which can serve to enhance their credibility. We identified these levers by interviewing experienced school leaders. For each lever, we propose a series of actions and provide concrete examples. The text concludes with an overview and questions designed to guide readers in formulating their own individual action plans.

Source credibility is a key influencing factor across both commercial and social marketing. It is perhaps even more important for the latter given that the issues under consideration generally have substantial implications for both individual and societal health and well-being. The Act-Belong-Commit campaign is a world-first population-wide application of social marketing in the area of positive mental health promotion. This study aims to focus on the perceived credibility of the Act-Belong-Commit campaign as a source of information about mental health as a predictor of three types of behavioural responses to the campaign: adopting mental health enhancing behaviours; seeking information about mental health and mental health problems; and seeking help for a mental health problem.

A state-wide survey was undertaken of the adult population in an Australian state where the Act-Belong-Commit campaign originated. The survey included measures of the above three behavioural responses to the campaign and measures of respondents’ perceptions of Act-Belong-Commit’s source credibility. Logistic regression analyses were performed to determine whether the three behavioural responses can be predicted based on perceived source credibility. The predictive performance of the model was examined by receiver operating characteristic curve analysis.

Greater perceived source credibility was significantly associated with having done something for their mental health and for having sought information, and an increased likelihood, but not significantly so, of having sought help for a mental health problem.

Despite the acknowledged importance of source credibility, there has been little published research that the authors are aware of that has looked at the impact of such on the effectiveness of social marketing campaigns. To the best of the authors’ knowledge, this is the first published study of the association between source credibility and behavioural response to a social marketing campaign.

Users often struggle to select choosing among similar online services. To help them make informed decisions, it is important to establish a service reputation measurement mechanism. User-provided feedback ratings serve as a primary source of information for this mechanism, and ensuring the credibility of user feedback is crucial for a reliable reputation measurement. Most of the previous studies use passive detection to identify false feedback without creating incentives for honest reporting. Therefore, this study aims to develop a reputation measure for online services that can provide incentives for users to report honestly.

In this paper, the authors present a method that uses a peer prediction mechanism to evaluate user credibility, which evaluates users’ credibility with their reports by applying the strictly proper scoring rule. Considering the heterogeneity among users, the authors measure user similarity, identify similar users as peers to assess credibility and calculate service reputation using an improved expectation-maximization algorithm based on user credibility.

Theoretical analysis and experimental results verify that the proposed method motivates truthful reporting, effectively identifies malicious users and achieves high service rating accuracy.

The proposed method has significant practical value in evaluating the authenticity of user feedback and promoting honest reporting.

The purpose of this research paper is to study attitudinal responses to the tone of a voluntary disclosure. It is known that tone can affect market response. Existing literature assumes that investors' attitudes mediate these effects, but these attitudinal mediators have not been directly measured. The authors are especially interested in cases where a firm is reporting poor financial results. The purpose is to trace the mechanism and conditions under which tone affects the credibility of a voluntary disclosure.

The authors conducted a 2 × 2 between-subjects study that manipulates financial performance (good/bad) and tone (positive/negative). The attitudinal dependent variable is the credibility of the management discussion, with persuasive intent as a mediator of the effects of tone on credibility.

In the case of bad financial results, a positive tone has a negative effect on credibility as the authors predict. This effect is fully mediated by perceived “persuasive intent”. In the case of good financial performance, credibility is higher when management adopts a positive tone, even though there, too, subjects perceive the persuasive intent.

The research paper establishes a bridge between the communications and finance literature on the effect of tone in voluntary disclosures. The empirical findings provide initial evidence and new detail regarding an attitudinal response (credibility) that the finance literature often assumes is responsible for mediating market responses to voluntary disclosures. One unexpected finding with interesting implications is that positive tone increases credibility in the case of good news. The implication is that a firm may indulge in taking a victory lap to celebrate good news, without harming the credibility of their corporate communications. Additional research is warranted that combines theory and methods from communications and finance, to further elaborate the attitudinal mechanisms behind the market effects of tone in voluntary disclosures.

At the most general level, the original contribution is the creation of a theoretical and methodological bridge between the communications and finance literature, regarding the effect of tone in voluntary disclosures. This research proposes an integrated theoretical framework, in which the concept of incentives shapes the relationships between the firm's financial situation, a disclosure's tone and its credibility. Methodologically, the authors employ an experimental method, which is more typical in the communications literature, to illuminate the attitudinal effects of tone that are frequently mentioned and assumed in the finance literature.

To elaborate the picture of credibility assessment by examining how participants of online discussion evaluate the informational credibility of conspiracy theories.

Descriptive quantitative analysis and qualitative content analysis of 2,663 posts submitted to seven Reddit threads discussing a conspiracy operation, that is, the damage of the Nord Stream gas pipelines in September 2022. It was examined how the participants of online discussion assess the credibility of information constitutive of conspiracy theories speculating about (1) suspected actors responsible for the damage, (2) their motives and (3) the ways in which the damage was made. The credibility assessments focussed on diverse sources offering information about the above three factors.

The participants assessed the credibility of information by drawing on four main criteria: plausibility of arguments, honesty in argumentation, similarity to one's beliefs and provision of evidence. Most assessments were negative and indicated doubt about the informational believability of conspiracy theories about the damage. Of the information sources referred to in the discussion, the posts submitted by fellow participants, television programmes and statements provided by governmental organizations were judged most critically, due to implausible argumentation and advocacy of biased views.

As the study focuses on a sample of posts dealing with conspiracy theories about a particular event, the findings cannot be generalized to concern the informational credibility conspiracy narratives.

The study pioneers by providing an in-depth analysis of the nature of credibility assessments by focussing on information constitutive of conspiracy theories.

This study aims to conceptualize the relationship of perceived artificial intelligence (AI) credibility with consumer-AI experiences. With the widespread deployment of AI in marketing and services, consumer-AI experiences are common and an emerging research area in marketing. Various factors affecting consumer-AI experiences have been studied, but one crucial factor – perceived AI credibility is relatively underexplored which the authors aim to envision and conceptualize.

This study employs a conceptual development approach to propose relationships among constructs, supported by 34 semi-structured consumer interviews.

This study defines AI credibility using source credibility theory (SCT). The conceptual framework of this study shows how perceived AI credibility positively affects four consumer-AI experiences: (1) data capture, (2) classification, (3) delegation, and (4) social interaction. Perceived justice is proposed to mediate this effect. Improved consumer-AI experiences can elicit favorable consumer outcomes toward AI-enabled offerings, such as the intention to share data, follow recommendations, delegate tasks, and interact more. Individual and contextual moderators limit the positive effect of perceived AI credibility on consumer-AI experiences.

This study contributes to the emerging research on AI credibility and consumer-AI experiences that may improve consumer-AI experiences. This study offers a comprehensive model with consequences, mechanism, and moderators to guide future research.

The authors guide marketers with ways to improve the four consumer-AI experiences by enhancing consumers' perceived AI credibility.

This study uses SCT to define AI credibility and takes a justice theory perspective to develop the conceptual framework.
