Using Social Cognitive Theory, Social Identity Theory, and Source Credibility, this study examined the role of instructor source credibility as related to exercise adherence. A one-time survey was given to participants of an eight-week exercise program. Hierarchical multiple linear regression was used to test hypotheses. Results indicate that perceived expertise was a significant predictor of intentions to adhere to class. Additionally, this study shows how Social Identity Theory can predict lower levels of identification in an exercise context. The scales used to text source credibility were shown to be accurate measures of perceived instructor expertise, likeability, and enthusiasm. Thus, these scales can be used to examine this subject in later studies.

The growth of YouTube has resulted in the industrialization of a platform that redefines mainstream success. Success measures such as endorsements and viewership are serving as motivational factors for YouTubers. YouTubers and brands want more views, but are those motivations effecting perception? While much research has focused on the effects that YouTube has on the brand, this study focuses on the effects that the brand has on the YouTuber. It also determines whether viewership affects YouTuber perception and whether it‟s a success measure worth using. Using the constructs of the source credibility theory, this study assessed the main effect of brand endorsement and viewership on perceived expertise and trustworthiness of YouTubers. After conducting an online experiment, findings suggest that non-brand endorsed YouTubers possess higher-rated expertise and trustworthiness. While viewership did not make a difference in perceived expertise, it did result in higher-rated trustworthiness when a YouTuber possesses lower viewership.

“Who says what to whom and of what consequence?” is a fundamentally communicative question. This dissertation provides answers to this question by examining receivers’ expectations about, perceptions of, and responses to, requests for compliance. This dissertation asks: What impact does source credibility have on responses to and evaluations of request for compliance? Do people who receive requests for compliance have different language expectations for high and low credibility sources? If receivers perceive self-benefit from complying with a request, will that affect their responses to or evaluations of the message or message source? To answer these questions, this dissertation responds to the call for studies to extend language expectancy theory by focusing on interpersonal influence attempts; the results herein provide researchers with the opportunity to offer refined specifications when making predictions about social influence outcomes. In addition, this dissertation is novel in that it examines the intersection between language expectancy theory and predicted outcome value theory. / text

Social Media Influencers (SMIs) and their sponsored posts on the Social Media represent a growing part of tomorrow’s digital marketing landscape. Marketers hire them to recommend their products to their large audiences through friendly and engaging social media posts. To please marketers, increasing and maintaining their audience size is of the utmost importance. Consequently, number of followers, likes, and comments have become the metrics of SMIs success. However, recent contradictory publications of business magazines and academic research raised the question of SMIs’ online popularity, credibility, and their efficiency as brand endorsers. Hence, an online-based survey experiment based examined the audience’s attitude of SMI credibility across three different level of online popularity using Ohanian’s (1990) source credibility model. Further, the relationship between SMI credibility and brand attitude, and the mediating effect of attitude toward sponsored post were investigated using a research model adapted from Attitude toward advertising models. The findings revealed that the more an SMI is popular, the more he is perceived as a credible brand advocate, and SMI credibility was found to positively and directly influences brand attitude. Semi-structured interviews strengthened the discussion of the quantitative results. Theoretical and managerial contributions of the study are presented and suggestions for future research ensue.

The purpose of this paper is to examine how consumers’ online purchase intention is impacted by sponsorship transparency and the use of disclosure. An online survey was collected from 135 people from 41 different countries around the world. The collected data was used to test the proposed four hypotheses and was analyzed with a linear regression test. The findings suggest that the ethical practice of sponsorship transparency negatively impacts purchase intention; and posits that an explicit sponsorship disclosure has no positive impact on purchase intention. However, the characteristic trait of the influencer, i.e. transparency and authenticity and their source credibility has a significant impact on prompting consumers toward purchase intention.

Purpose – The purpose of this research is to create an understanding of how influencer marketing could be used to increase the purchase intention in an area of a high involvement product in a niche market. Since this study is collected together with a Swedish golf company, the golf industry was evaluated. In order to fulfill the purpose, the social media influencer value (SMIV) model was adopted in this study. Method – A quantitative experiment was conducted through the use of experimental vignette methodology (EVM) together with a qualitative validity check-in form of an interview with a key person from the industry. The main data was collected through a combination of exposure to the independent variable (through a stimulus) and a set of following questions (a questionnaire). The questionnaire was sent out to the company’s consumer through email and to analyze the collected data an analysis of covariance (ANCOVA) was used. Findings – In the collected data, evidence indicating that golf is a high involvement activity where the participants put down a lot of time and effort in the sport was found. In the SMIV model three significant paths was found between expertise and purchase intention, similarity and purchase intention, and usefulness and purchase intention. All three independent variables had a positive impact on purchase intention which tells us that when expertise, similarity, or usefulness increases, consumers purchase intension increases as well. Theoretical and practical implications – The results in this study contributes to current literature in the area of influencer marketing by confirming some relationships but also by extending the literature. The study also contributes to important insights for marketing practitioners since the results present important variables to consider when using influencer marketing to create purchase intention. It also creates meaningful insights for the influential person itself and open up for further research in the area of the effect of influencer marketing in a high involvement product.

Misinformation remains pervasive in digital platforms, shaping how individuals receive news online. Prior work suggests that credibility perceptions of misinformation can differ based on the modality of the misinformation message. Informed by the MAIN model, this quantitative study conducted two separate 2 (Modality: video or text) x 2 (Social endorsement cues: high vs. low) between-subject experiments to assess the influence of message modality and social endorsement cues on misinformation credibility judgments. The experiments reviewed two different topics of misinformation: artificial intelligence technology malfunction (N = 296) and a cure for cancer (N = 306). Results for Study 1 on artificial intelligent technology malfunction misinformation indicated that participants who viewed the video modality judged a higher perception of source expertise and message credibility. The results of Study 2 suggested that the text presentation of health misinformation prompted higher message elaboration relative to the video conditions. Findings suggest that modality does influence how people judge misinformation messages depending on the subject matter. In addition, source credibility influences how people judge message credibility. The paper concludes with a discussion of theoretical implications and practical applications.
