Exploring the credibility of online celebrities' Instagram profiles in influencing the purchase decisions of young female users

Is online shopping addiction still a depressive illness? -- the induced consumption and traffic trap in live E-commerce

While immersive shopping has injected new vitality into China's e-commerce, it has also resulted in consumers' over-reliance on online shopping. Psychological studies have linked online shopping addiction with depression, but business practices challenge this conclusion. This study, grounded in addiction theory, developed a theoretical model, and conducted an online survey with 214 live-streaming shoppers using structural equation modeling for validation. The primary focus was on determining whether consumers truly become addicted to online shopping in the four stages of the addiction model. The study unveils the process of consumers becoming addicted to online shopping. It explores the moderating role of perceived risk in the relationship between utilitarian and hedonic purchases and online shopping addiction. The findings suggest that through tactics such as traffic promotion, traffic trapping, anchor feature utilization, and incorporation of consumer aesthetics, merchants may induce utilitarian and hedonic purchases, leading to addiction to live-streaming shopping among consumers. Furthermore, perceived risk significantly and negatively moderates the relationship between utilitarian purchases and online shopping addiction. Our research indicates that merchants intentionally create external stimuli, enticing consumers to indulge in online shopping, suggesting that online shopping addiction is not merely a simple psychological state but may be influenced by external factors. This study provides novel insights into the phenomenon of online shopping addiction while offering valuable recommendations for consumers seeking to avoid succumbing to its allure.

Information literacy in the digital age: information sources, evaluation strategies, and perceived teaching competences of pre-service teachers

Introduction

Information literacy has become indispensable in navigating today's fast-paced media environment, with teachers playing a pivotal role in fostering reflective and critical digital citizenship. Positioned as future gatekeepers, pre-service teachers are the key to teaching media skills and especially information literacy to future generations of pupils. Given the particular challenges facing educators today compared to previous generations, it is important to determine whether the next generation of teachers feel adequately prepared and perceive themselves as competent to pass on these skills to their future pupils. However, previous research has highlighted deficiencies in formal learning opportunities at universities, underscoring the need for further investigation into pre-service teachers' information acquisition, evaluation practices as well as their perceived relevance to teaching, and person-related factors associated with their perceived competence in teaching information literacy.

Method

An online questionnaire was presented to participants, employing a mixed-method approach. We qualitatively examined the sources of information used by pre-service teachers and the evaluation strategies they employ, while quantitatively analyzing relationships between pre-service teachers' person-related factors and their perceived teaching competence. Participants assessed their perceived teaching competence, perceived learning opportunities, self-efficacy (general and related to information assessment), perceived informedness, selective exposure, need for cognition, need for cognitive closure, and mistrust in media coverage.

Results

Data from 371 participants revealed digital media dominance in information acquisition over traditional sources, albeit with a prevalence of surface-level evaluation strategies over reflective approaches. Two distinct dimensions of perceived competence in teaching information literacy emerged: one focusing on information assessment while the other centers on the understanding of news creation processes. Perceived competence in teaching information literacy was significantly associated with self-efficacy in information assessment, perceived informedness, selective exposure to information as well as perceived learning opportunities focusing on information evaluation. Moreover, pre-service teachers employing diverse information evaluation strategies demonstrated a heightened sense of perceived competence in teaching information assessment.

Discussion

Our results provide valuable insights into the multifaceted nature of pre-service teachers' perceived competence in teaching information literacy. Theoretical implications for future research as well as practical implications for teacher education and the structure of future curricula are discussed.

Consumers purchase intention in live-streaming e-commerce: A consumption value perspective and the role of streamer popularity

The rapid development of live-streaming e-commerce has driven billions of sales revenues and made customers' purchase intention a life-and-death issue for sellers. This study examines the influencing factors of customers' purchase intention from a value perspective by adopting and extending the Theory of Consumption Values (TCV). We also incorporated streamer popularity as a moderating variable to reveal its significant impact on live-streaming e-commerce. This study collected 457 valid online questionnaires from Chinese live-streaming e-commerce users. Our findings show that five of six consumption values, namely functional, social, emotional, conditional, and self-gratification value, are significant drivers of purchase intention. In addition, streamer popularity has strengthened the influence of functional, social, emotional, and self-gratification value on purchase intention. This study deepens the current understanding of live-streaming and customer value research by establishing and validating a comprehensive research model, and reveals the decisive role of multi-dimensional value and streamer popularity in live-streaming industry. The research findings could guide live-streaming merchants to increase sales by reallocating their resources to different consumption values and optimising their investment strategy in popular streamers.

The Impact of Information Presentation on Consumer Perceptions of Cricket-Containing Chocolate Chip Cookies

As a source of protein and other nutrients for a growing population, edible insect production offers environmental and sustainability advantages over traditional meat production. Although around 2 billion people consume insects worldwide, Western consumers are still reluctant to practice entomophagy, hindered largely by neophobia and negative emotions. In addition to sensory quality and safety, an informational component may be crucial to consumers' decision making involving insect consumption. In this study, three different information types, namely text, image, and a tangible product, were used to convey information about chocolate chip cookies (CCCs) containing cricket flour. The nature of the information was related to the ingredient usage level (5%), the type of insect (cricket), nutritional values, sustainability benefits, packaging, celebrity endorsement, and/or visual appearance of an actual product. Consumers' willingness to consume (WTC), acceptance, and purchase intent (PI) were measured in response to each informed condition. Once informed of the insect ingredient, all scores significantly (α = 0.05) dropped. The lowest WTC (1.97 ± 1.06, Text), acceptance (3.55 ± 2.23, Image), and PI (1.85 ± 1.05, Text) scores were found after identifying cricket as the insect ingredient. Compared to other informed conditions, the presentation of a real chocolate chip cookie containing insects achieved the highest scores on all affective scores (WTC: 3.4 ± 1.04, acceptance: 6.17 ± 1.89, PI: 3.07 ± 1.09). The greatest improvement in scores was observed after information about nutrition and sustainability benefits (based on ANOVA), which was more impactful for males than females (based on a t-test). Celebrity endorsement did not have a significant effect. The presentation of the actual CCC containing cricket flour (for visual observation only) significantly increased WTC, acceptance, and PI compared to presenting text and images alone. Acceptance, WTC, and certain information cues were significant predictors of PI for CCCs containing cricket flour.

A model of purchase intention of complementary and alternative medicines: the role of social media influencers' endorsements

BACKGROUND

Social Media Influencers (SMIs) are a fashionable way of marketing products by creating electronic word-of-mouth (e-WOM) on social media. The marketing of complementary and alternative medicines (CAMs) by SMIs is becoming increasingly popular and gaining credibility within consumers on social media platforms. Nonetheless, advising about healthcare products on social media should be examined as it is different from endorsing other kinds of commercial products. The aim of this study is to develop a model that provides the underlying mechanisms of the stimuli of SMIs on social media towards consumers' purchase intention of CAMs.

METHODS

This study used best fit framework synthesis methods to develop the model. A priori theory selection was conducted by identifying a BeHEMoTh strategy (Behavior of Interest, Health context, Exclusions and Models or Theories) to systematically approach identifying relevant models and theories relative to the research aim. Further evidence derived from primary research studies that describe the behavior identified is coded against selected a priori theory to develop the model.

RESULTS

This study presents a novel model for understanding the purchase behavior of CAMs using SMIs as a marketing strategy. The model included two well-known theories (theory of planned behaviour theory and source credibility theory) as well as extensive existing research from a multidisciplinary perspective. The model is exclusively designed to help identify elements affecting perceived source credibility and factors that have an influence over consumers' preferences to purchase CAMs by taking into consideration SMIs' endorsements.

CONCLUSIONS

This study provides unique insights introducing new research areas to health literature and offers, new roles for healthcare professionals in this digital era by gaining new skills and competencies required to provide more credible and accurate information about CAMs. The study also highlights the new marketing era of online health-related product endorsements and recommends that policymakers and researchers carefully evaluate the impact of SMI's on the use of CAMs, as well as to regulate the content of these promotional materials.

Fun with Frustration? TikTok Influencers' Emotional Expression Predicts User Engagement with COVID-19 Vaccination Messages

This study examined what kinds of TikTok video and message features are associated with user engagement in the context of COVID-19 vaccination. Content analysis was applied to study a sample of 223 COVID-19 vaccination-related videos from creators with at least 10,000 followers. The content analysis involved coding themes, video formats, the valence of attitude toward vaccination, and emotional expressions from the influencers. A majority of videos showcased personal vaccination experiences, followed by fictitious dramas and instructional information. More fictitious dramas expressed unclear attitudes, neither explicitly supporting nor opposing the COVID-19 vaccine, compared to personal vaccination stories and instructional videos. Some imaginative and dramatic scenes, such as zombie transformation or dramatic spasms after taking the vaccines, were widely imitated across influencers, perhaps humorously, and raised concerns about diminishing positive images of vaccine uptake. Videos with simultaneous expression of humor and frustration significantly predicted engagement when the video content opposed or was uncertain about taking the vaccine, implying the effectiveness of mixed emotional attributes within a message. This study provides insight into how social context and message choices by creators interact to influence audience engagement.

Young adults' sought gratifications from, and perceptions of food advertising by, social media influencers: a qualitative approach

BACKGROUND

This study aims to explore young adults' sought gratifications from social media influencers and whether they are exposed to food advertising by influencers. Further, it aims to understand how young individuals perceive food advertisements by social media influencers.

METHODS

This qualitative study was conducted on 17 students from two public universities-King Abdul Aziz and Jeddah universities-located in the City of Jeddah, Saudi Arabia, using in-depth, face-to-face, and semi-structured interviews. The participants were active users of social media platforms who followed at least one influencer. Thematic analysis was used to analyse the data. The COREQ guidelines for reporting qualitative research (see Additional file 2) were followed when stating the findings.

RESULTS

The findings reveal ten themes, that is, seven gratifications sought by young adults-broadening knowledge, perceived usefulness, self-improvement, boosting positivity, fostering morale, reinforcing inspiration, and passing time/enjoyment-and three themes (i.e. repeated, authentic, and unhealthy) that describe how Saudi young adults perceive food advertising.

CONCLUSION

This study contributes to social media influencer marketing by identifying the factors that motivate young consumers to follow influencers, and it elucidates the extent to which young adults are exposed to food marketing, adding to the body of literature on food advertising.

Detection of opinion leaders: Static vs. dynamic evaluation in online learning communities

Opinion leaders play a critical role in maintaining the functioning of online communities. This study aims to detect opinion leaders in online learning communities by evaluating the influence of users within the community. We use Baidu Post Bar's Python learning community as an example and employ the catastrophe progression method to statically evaluate the influence of users in three dimensions: user creativity, user posting quality, and user online interaction. Based on this, we introduce the dual-incentive control line to dynamically evaluate users' influence from 2016 to 2020 regarding speed change characteristics, thus scientifically detecting opinion leaders in online learning communities. Compared to the static evaluation method, the results show that our proposed dynamic evaluation method can more effectively reveal the dynamic development trend of users' influence, thus accurately detecting opinion leaders. Moreover, this "invisible" development trend is fully reflected in the setting of the dual-incentive control line.

Propaganda Information of Internet Celebrity Influence

At present, internet celebrity marketing has become a driving force for the growth of mobile e-commerce; however, it has also become more apparent that the credibility and authenticity of the internet celebrity is directly correlated to the success of the marketing model. Therefore, in order to entice consumers into purchasing products, cooperations and internet celebrities must be deemed trustworthy. In addition, there are several factors that influence the trust between internet celebrities and consumers. To highlight these factors, this paper constructed an internet celebrity marketing model from the perspective of trust and takes internet celebrity features, marketing character, and product factor as three constructs. Furthermore, eight independent variables are defined, and the corresponding items are designed. Through a quite large data survey and analysis, they have three findings: all eight independent variables have significant influence on trust, and internet celebrities' popularity, interactivity, and professionalism are the top three important factors.

Non-green influencers promoting sustainable consumption: Dynamic norms enhance the credibility of authentic pro-environmental posts

Social media influencers can raise awareness for sustainability, and establish norms related to a more sustainable lifestyle. Although non-green influencers can reach a wider audience, they might face credibility issues when communicating about sustainable consumption. In the present 2×2 online mixed method experiment (N = 386), we explored the effect of two credibility-enhancing strategies (authenticity vs. referring to experts) and the presence (vs. lack of) of dynamic norms (information about how other people's behavior is changing over time) on the perceived credibility of the post. Results indicated that referring to expert opinion enhanced perceived post credibility. However, if an authentic message was combined with dynamic norms, it reduced the frequency of mentions of the lack of credibility. Both credibility measures were positively associated with the persuasiveness of the message. These findings can contribute to the growing literature of credibility-enhancing strategies and dynamic norms. The study also provides practical suggestions for non-green influencers on effective communication of sustainable consumption.

Influencer Worship and Self-Connection with the Promoted Brands on Social Media: Why Benign Envy and Trait Competitiveness Matter

The objective of this study was to investigate the relationship between influencer worship and consumers' self-connection with the brands promoted by the influencer in social media contexts. Data from 698 active social media users who follow influencers were collected to test the conceptual framework. The findings support the positive link between influencer worship and consumers' self-connection with the brands promoted by the influencer on social media and suggest that this relationship is mediated by the activation of benign envy. The results also confirm the positive moderating effect of trait competitiveness on this relationship. Specifically, the effect is stronger for individuals with a higher level of competitive orientation. The findings contribute to the understanding of the relationship between influencers and their followers through computer-mediated environments. Theoretical contributions and managerial implications are presented.

The effect of social media influencers' on teenagers Behavior: an empirical study using cognitive map technique

The increase in the use of social media in recent years has enabled users to obtain vast amounts of information from different sources. Unprecedented technological developments are currently enabling social media influencers to build powerful interactivity with their followers. These interactions have, in one way or another, influenced young people's behaviors, attitudes, and choices. Thus, this study contributes to the psychological literature by proposing a new approach for constructing collective cognitive maps to explain the effect of social media influencers' distinctive features on teenagers' behavior. More in depth, this work is an attempt to use cognitive methods to identify adolescents' mental models in the Tunisian context. The findings reveal that the influencers' distinctive features are interconnected. As a result, the influencer's distinctive features are confirmed in one way or another, to the teenagers' behavior. These findings provide important insights and recommendations for different users, including psychologists and academics.

Technology supports me: Perceptions of the benefits of digital technology in adolescents

Background

Technology plays a significant role in the lives of adolescents. Our knowledge is predominantly based on research exploring the risks associated with it, but adolescents also feel that technology supports their lives. This has received less consideration. Therefore, we aim to examine how adolescents perceive the benefits of digital technology.

Methods

We used qualitative data collected as part of the international Health Behaviour in School-Aged Children study. We conducted online, semi-structured interviews with 15 Slovak adolescents who came from three different types of secondary schools based on their graduation systems (mean age: 15.33; 20% boys). The data were analyzed using consensual qualitative research and thematic analysis.

Results

We identified five main themes based on the comments of adolescents: 1. I know (source of information, formal and non-formal education); 2. I can (smart device, helpful tool); 3. I am connected/included (social interactions); 4. I have my comfortable place (leisure time, creating my alternative world); and 5. I work on my future (self-development).

Conclusion

Adolescents perceived digital technology as mostly supportive and a helpful tool in their lives. The potential benefits of digital technology should be better reflected in public perception and policy, as the societal debate is mostly dominated by perceived disadvantages and risks.

Sociomaterial influence on social media: exploring sexualised practices of influencers on Instagram

Purpose

Relying on social influence and sociomateriality theories, this research provides new insights about the social and material drivers relating to the sexualisation of online behaviour of social media influencers.

Design/methodology/approach

Using a netnographic approach, observation data were gathered from the Instagram accounts of 20 influencers dedicated to beauty and fashion. In addition, 15 in-depth interviews were conducted with women adopting sexualisation practices online. The data were analysed using an abductive strategy; all materials were coded according to thematic analysis principles.

Findings

The authors observe that sexualisation is a result of a complex system of social interactions encouraged and reinforced by multiple factors and actors. In particular, the authors outline the major influence of technology that has become a non-human authority defining implicit norms and shaping the beliefs and behaviours of women influencers.

Originality/value

In contrast to existing literature which mainly focuses on the negative consequences of sexualisation, this work sheds some light on social constructs in social media. The authors contribute to the growing literature on social media influencers. Although many works focus on their persuasiveness, this work helps to better understand the social setting, motivations and pressures that are contained in social and technological contexts.

The influences of expressive and instrumental social ties in social commerce: integrating dyadic views from buyers and sellers

Purpose

Entrepreneurs and individual sellers heavily leverage their social ties embedded in social media, expressive or instrumental, to penetrate the market and achieve business success. However, the extant social commerce literature offers limited understanding on how different forms of buyer−seller social ties embedded in social media affect buyers' purchase behaviors. The study draws on the theoretical lens of social ties and proposes an integrative theoretical framework to understand the direct and indirect influences of expressive and instrumental ties (ExTSM and InTSM) between buyers and sellers on buyers' purchase intention (PI) in social commerce.

Design/methodology/approach

The authors first validated the measures of ExTSM and InTSM with survey data from 166 Weibo commerce buyers. They then tested their theoretical framework and hypotheses with survey data from 246 buyer−seller dyads in WeChat commerce.

Findings

With a buyer-centric view, (1) ExTSM and InTSM, respectively, had a direct negative and a positive influence on PI; (2) both trust and perceived product value displayed inconsistent mediation effects on the negative relationship between ExTSM and PI; and (3) only perceived product value mediated the positive influence of InTSM on PI. From sellers' viewpoint, (1) their ExTSM and InTSM with buyers were mixed up, and (2) the mingled social ties negatively impacted buyers' purchase intention.

Originality/value

The findings of the study advance the theoretical understanding of social commerce and offer practical guidance for small and medium-sized enterprises to effectively utilize social media for business purposes.

Motivation Scale for Using Social Network Sites: Comparative Study between Facebook, Instagram, Twitter, Snapchat and LinkedIn

The increasing number of Social Network Sites (SNSs) and their changing nature raise the question of why people use them. This research has a twofold objective: first, to develop a motivation scale for using SNSs; second, to compare the motivational SNSs profile of Facebook, Instagram, Twitter, Snapchat and LinkedIn. Two studies on 364 university students, using exploratory and confirmatory factor analyses, established six motivations: entertainment, social interaction, seeking information, instrumental use, self-documentation and self-enhancement. Regressions then examined the association between motivations for using SNSs, social influence measures (descriptive and injunctive norms), and frequency of use of Facebook, Instagram, Twitter, Snapchat, and LinkedIn. The results showed that social norms complement the motivations to use SNSs. Twitter use was associated with an information-seeking SNSs motivational profile. LinkedIn, Facebook, and Instagram were associated with self-documentation on SNSs. Snapchat was rather associated with instrumental motivations on SNSs. However, while all SNSs were associated with descriptive norms, only Facebook and LinkedIn were associated with injunctive norms (i.e., peer pressure). The results are discussed by applying a cross-media perspective to new motives behind SNSs use.

Go vegan! digital influence and social media use in the purchase intention of vegan products in the cosmetics industry

Social media have expanded the exposure of vegan consumption decisions and practices through the greater reach of opinions issued digitally by individuals concerned about ethical and environmental issues. Some of these people have reached considerable numbers of followers virtually, becoming digital influencers with built-in credibility that makes them opinion leaders. Considering them, this study aims to analyze the relationship between source credibility and the social media use in the purchase intention of vegan products endorsed by digital influencers, focusing on the cosmetics industry. We used the cross-sectional survey method and adopted Structural Equation Modeling to analyze the relationships between the variables from 190 valid questionnaires. We identified that both the social media use and the source credibility influence the purchase intention of vegan cosmetic products. The ability of digital influencers to shape consumer intentions was recognized, even though the products they endorse do not represent the follower's philosophy of life-for example, a nonvegan follower who intends to consume a vegan cosmetic from the digital influencer endorsement. Furthermore, we identified that the source credibility influences the social media use that is the influencer also shapes the individual digital behavior.

User profiling and role evaluation of government microbloggers in the context of public emergencies

Purpose

This study aims to profile the government microbloggers and evaluate their roles. The results can help improve the governments' response capability to public emergencies.

Design/methodology/approach

This study proposes the user profiling and role evaluation model of government microbloggers in the context of public emergencies. The indicators are designed from the four dimensions of time, content, scale and influence, and the feature labels are identified. Three different public emergencies were investigated, including the West Africa Ebola outbreak, the Middle East respiratory syndrome outbreak and the Shandong vaccine case in China.

Findings

The results found that most government microbloggers were follower responders, short-term participants, originators, occasional participants and low influencers. The role distribution of government microbloggers was highly concentrated. However, in terms of individual profiles, the role of a government microblogger varied with events.

Social implications

The findings can provide a reference for the performance assessment of the government microbloggers in the context of public emergencies and help them improve their ability to communicate with the public and respond to public emergencies.

Originality/value

By analyzing the performance of government microbloggers from the four dimensions of time, content, scale and influence, this paper fills the gap in existing literature on designing the user profiling and role evaluation model of government microbloggers in the context of public emergencies.

Vlogger's persuasive strategy and consumers' purchase intention: The dual mediating role of para-social interactions and perceived value

It is a new advertising marketing method for commodity companies to use vloggers to endorse their products, and to influence consumers' attitudes and decisions. In view of this phenomenon, there are few studies on the relationship between vloggers and consumers, and this study aims to explore how the persuasive strategies used by vloggers to promote products influence consumers' purchase intentions. Based on the concepts of Aristotle's persuasion theory, this study extracts two specific persuasive approaches, "two-sided messages" and "emotional appeal," to explore consumers' perceptions of them and the effectiveness of these two strategies. At the same time, para-social interaction and perceived value as intermediary factors are also included in the study for further discussion. The study empirically analyzed a sample of 511 questionnaires from participants who had purchased products recommended by vloggers and came to the following conclusions: (1) vloggers can enhance consumers' purchase intention by adopting two-sided messages persuasion when promoting products; (2) vloggers' emotional persuasion can enhance consumers' purchase intention; (3) as an intermediary variable, para-social interaction plays a more obvious role in vloggers' persuasion by appealing to emotions. The audience can have common feelings with vloggers, and they are more connected with each other, thus increasing their willingness to buy; (4) Perceived value, as an intermediary variable, plays a more obvious role in vloggers' persuasion with the two-sided messages. The two-sided messages can show vloggers' credibility and more abundant information about products, so that consumers have a positive perception of product value, and the direct persuasion effect of the two-sided messages is greater. Based on the results of the study, this paper helps vloggers to adopt different persuasive approaches for different types of audiences, choose the proper marketing methods, attract the potential customers, and achieve such purposes as enriching product marketing forms and increasing market share.

Source Credibility Theory: SME Hospitality Sector Blog Posting During the Covid-19 Pandemic

During the recent Covid-19 pandemic SMEs in the hospitality sector had to develop new ways of increasing consumer engagement and maintaining business activity. This study examines the effect of using blogs to counter the detrimental effect of pandemic lockdowns. A survey method was deployed with 449 respondents. Analysis used SEM PLS. The findings show trustworthiness and reputation positively affects credibility, but promotional incentives and expertise do not affect credibility. The findings also suggest that unverified information sharing mediates the relationship between credibility and loyalty. Information System (IS) researchers can systematically develop approach using big data to identify false information. This research contributes to knowledge of both IS researchers and SMEs in hospitality sector. SMEs in hospitality sector can partner IS and use this research as an example of method for recovering from crisis by the adoption of blog posts, as well as working remotely with IS researchers to explore data sources and research techniques to investigate false information.

COVID-19 messages in sponsored social media posts: The positive impact of influencer-brand fit and prior parasocial interaction

This study explores the dissemination potential of a COVID-19 message embedded in a sponsored social media post. The moderating role of prior parasocial interaction and influencer-brand fit were considered. 365 respondents participated in the study. A 3 (control, congruent, incongruent brand) × 2 (control, COVID-19 message) between-subject online experiment was designed and executed. Data were analyzed using a mediated moderation model. Results indicated that the three-way interaction of the COVID-19 message, brand presence and prior parasocial interaction affected the perceived influencer credibility, attitudes towards the social media post, and the behavioral engagement with the post. When the COVID-19 message was included in the post, increased prior parasocial interaction intensified the positive effect of influencer-brand fit on influencer credibility, which in turn resulted in a more positive attitude towards the post, and a higher behavioral engagement. Theoretical and practical implications were discussed.

Tech, Sex, and E-cigarettes: The Gendering of Vape Promotion on Instagram

The promotion of vape products on social media has been implicated in increasing rates of e-cigarette usage, particularly among youth and young adults. While research has examined overall trends in vape-related content across a number of platforms, the role that social media "influencers" play in promoting vaping and potentially augmenting this public health crisis has been insufficiently explored. The present study examined 44,052 Instagram posts by 60 male presenting and 60 female presenting vape influencers to understand how influencer gender mediates the performance of vape culture online. Our textual and visual analysis of these influencers' posts over one year revealed significant bifurcations based on gender. Independent sample t-tests showed statistically significant gender differences in word frequency. Male-presenting influencers tended to emphasize their expertise with vape devices as technologies, while female-presenting influencers tended to focus on their own appearance. Further, factor analysis indicated six major categories of textual features, and multiple linear regression tests showed varying levels of user engagement with the different categories across both genders. Chi-square tests indicated that female-presenting influencers highlighted their own bodies in the visual content of their posts, whereas male presenting influencers often posted images of vape devices or their component parts alone. These findings suggest that gender presentation plays an important role in shaping vape influencers' promotional tactics and vape-related content on Instagram, and also provides insights into what kinds of content receive the most user engagement. This study can therefore help inform interventions to mitigate the impact of social media vape promotion.

Systematic Bias in Self-Reported Social Media Use in the Age of Platform Swinging: Implications for Studying Social Media Use in Relation to Adolescent Health Behavior

Public health researchers are increasingly interested in the potential relationships between social media (SM) use, well-being, and health behavior among adolescents. However, most research has assessed daily SM time via self-report survey questions, despite a lack of clarity around the accuracy of such reports given the current tendency of youth to access SM on multiple electronic devices and cycle between multiple SM platforms on a daily basis (i.e., platform swinging). The current study investigates the potential for systematic reporting biases to skew findings. Three hundred and twenty incoming college students downloaded software on their computers, tablets, and smartphones to track their active use of Facebook, Twitter, Instagram, and Snapchat over a 2-week surveillance period and then self-reported their average daily minutes on each platform immediately after. Larger proportions of students over-estimated than under-estimated their use, with the largest overestimations found on the most heavily used platforms. Females logged significantly more SM time and were less accurate in reporting than were males and, independently, the likelihood of substantial inaccuracies in reporting total SM time and time on most individual platforms increased with each additional SM platform participants reported using. Findings demonstrate that self-reported estimates of SM time among adolescents in the age of SM platform swinging are prone to substantial error and may lead to biased conclusions about relationships between variables. Alternative measurement approaches are suggested to improve the validity of future research in this area.

Impact of online convenience on generation Z online impulsive buying behavior: The moderating role of social media celebrity

This research aims to determine which dimensions of online convenience influence generation z consumers’ cognitive and affective attitudes and online impulsive buying behavior. The moderating effect of social media celebrity is also investigated to examine the attitude-behavior gap. A total of 348 responses from Chinese users who followed digital celebrities were received using purposive sampling. Data analysis and hypothesis testing were carried out using SmartPLS, version 3 (partial least squares). The results indicated that relationship convenience, possession convenience, post possession conveniences, transaction convenience, and evaluation convenience have a crucial impact on cognitive and affective attitudes. Similarly, cognitive and affective attitudes are significant and positive predictors of generation z consumers’ online impulsive buying behavior. Moreover, empirical results supported the moderating role of social media celebrities that aid marketers in selecting a product endorser. The implications for marketers and policymakers are discussed based on the above research findings. Moreover, future research directions are suggested.

Impact of Perceived Influence, Virtual Interactivity on Consumer Purchase Intentions Through the Path of Brand Image and Brand Expected Value

Many researchers are currently showing interest in researching consumers who are purchasing the products with the help of new tools, and new kinds of markets are emerging rapidly. M-commerce is a prevalent mode of marketing and is famous among young people of Pakistan. Current research is planned to check the status of consumer purchase intentions (PIs) using perceived influence, virtual interactivity, brand image, and brand expected value among customers who purchase their products with the help of m-commerce. Data was collected from customers who were engaged in buying with the help of m-commerce by using the convenience sampling technique and 227 complete questionnaires were used in final analysis. This research examines the direct impact of perceived influence, virtual interactivity, brand image, and brand expected value on PIs and finds the indirect effect of brand image and brand expected value on the relationships of perceived influence and virtual interactivity with PIs. Results indicate that all the hypotheses of direct relationships are accepted except the hypothesis for the relation of virtual interactivity with consumer PIs. Virtual interactivity has an insignificant positive impact on consumer PIs. Brand expected value has a strong positive effect on consumer PIs among all. The current study proposed four mediational hypotheses. All the proposed mediational hypotheses are accepted.

Determining the Role of Influencers’ Marketing Initiatives on Fast Fashion Industry Sustainability: The Mediating Role of Purchase Intention

Celebrity influence plays a significant role in fostering the consumers’ impulse buying tendency and purchase intention. In the modern advertising era, the celebrity endorsement characteristics have driven the firms’ promotion campaigns, stimulating consumer purchasing behavior through celebrity branding. The study signifies the relationship between celebrity’s traits of trustworthiness, attractiveness, credibility, and expertise influence consumers’ impulse behavior. The data was collected from the 371 customers of the fast fashion industry by using the convenient-sampling technique. SMART-PLS was used for data analysis by applying structural equation modeling. The study results show that celebrity trustworthiness, the attractiveness of a celebrity endorser, the credibility of a celebrity endorser, and celebrity expertise positively impact purchase intention and impulse buying tendency. Purchase intention plays a mediating role between independent and dependent variables.

Employing Eye Tracking to Study Visual Attention to Live Streaming: A Case Study of Facebook Live

In recent years, the COVID-19 pandemic has led to the development of a new business model, “Live Streaming + Ecommerce”, which is a new method for commercial sales that shares the goal of sustainable economic growth (SDG 8). As information technology finds its way into the digital lives of internet users, the real-time and interactive nature of live streaming has overturned the traditional entertainment experience of audio and video content, moving towards a more nuanced division of labor with multiple applications. This study used a portable eye tracker to collect eye movement information from participants watching Facebook Live, with 31 participants who had experience using the live streaming platform. The four eye movement indicators, namely, latency of first fixation (LFF), duration of first fixation (DFF), total fixation durations (TFD), and the number of fixations (NOF), were used to analyze the distribution of the visual attention in each region of interest (ROI) and explore the study questions based on the ROIs. The findings of this study were as follows: (1) the fixation order of the ROIs in the live ecommerce platform differed between participants of different sexes; (2) the DFF of the ROIs in the live ecommerce platform differed among participants of different sexes; and (3) regarding the ROIs of participants on the live ecommerce platform, participants of different sexes showed the same attention to the live products according to the TFD and NOF eye movement indicators. This study explored the visual search behaviors of existing consumers watching live ecommerce and provides the results as a reference for operators and researchers of live streaming platforms.

What drives Taobao live streaming commerce? The role of parasocial relationships, congruence and source credibility in Chinese consumers' purchase intentions

The year 2021 is one of the most significant years for live streaming commerce, since numerous sectors and businesses have begun to sell their items in the form of live broadcast influence. Especially in China, Taobao live streaming often promotes an event by inviting internet celebrities to cooperate with brands to broadcast the products. For many brands, that is a very successful technique for increasing conversion rates. Researchers have lately grown interested in investigating the factors influencing the purchase decisions of Chinese consumers in the context of Taobao live streaming commerce with online celebrities. The present study is the first to theoretically combine three primarily literature-based disciplines, including source credibility, match-up hypothesis, and parasocial relationship theory, into a unified framework to bridge the research gaps. In this study, the quantitative method was employed through the use of partial least square structural equation modeling (PLS-SEM). The SmartPLS 3.0 software was applied to examine the proposed model. The data were obtained from 454 Chinese consumers who have ever purchased a cosmetic product from a famous internet celebrity on Taobao live streaming. The results indicated that the positive impact of a celebrity endorsers' perceived expertise was the powerful antecedent that affected purchase intentions, while celebrity endorsers' perceived attractiveness and trustworthiness had no significant effect. A good match-up between celebrity and product can improve the celebrity endorsers' perceived attractiveness, trustworthiness, and expertise. Moreover, it was found that the celebrity endorsers’ perceived expertise acted as a mediator of the relationship between celebrity-product congruence and purchase intentions. Finally, the findings showed that parasocial relationships have vital mediating effects on increasing purchase intentions.

The Importance of Social Influencer-Generated Contents for User Cognition and Emotional Attachment: An Information Relevance Perspective

It has become a marketing trend for marketers to use influencers to advertise and sell products because influencers can affect the attitudes and decision-making of other social media users. Most previous research on influencer marketing has concentrated on its effectiveness as a promotional tool. In contrast, there have been limited studies on the influencer-social media user relationship. The relationship that influencers have with other social media users is the foundation for the success of influencer marketing. Therefore, it is critical to investigate the factors that affect the influencers’ relationships with other users. In accordance with the concept of information relevance, this study presents a model relating the various attributes of influencer-generated content with emotional attachment and information quality to examine the relationship between influencers and other social media users. The findings of a survey of 280 respondents indicate that the interestingness, novelty, reliability, and understandability of influencer-generated content can effectively increase users’ emotional attachment to influencers. Reliability and understandability can also have a significant positive impact on information quality. This eventually inclines social media users to follow or recommend influencers to others, which can increase the popularity of influencers. This study helps researchers and marketers advance their understanding of influencers’ relationships with other social media users and offers management-related recommendations for influencers and marketers.

Can you be Mindful? The Effectiveness of Mindfulness-Driven Interventions in Enhancing the Digital Resilience to Fake News on COVID-19

This study explores the factors that influence the dissemination process of and public susceptibility to fake news amidst COVID-19. By adopting a qualitative approach that draws on 21 interviews with social media users from the standpoint of source credibility and construal level theories, our findings highlight motives of news sharers, platform features, and source credibility/relatedness as major factors influencing the dissemination of and public susceptibility to fake news. The paper further argues that public susceptibility to fake news can be mitigated by building an integrated approach that combines a tripartite strategy from an individual, institutional and platform level. For example, educating the public on digital resilience and enhancing awareness around source credibility can help individuals and institutions reflect on news authenticity and report fake news where possible. This study contributes to fake news literature by integrating concepts from information management, consumer behaviour, influencer marketing and mindfulness to propose a model to help authorities identify and understand the key factors that influence susceptibility to fake news during a public crisis such as COVID-19.

Picturing Mental Health on Instagram: Insights from a Quantitative Study Using Different Content Formats

Background: COVID-19 has changed individual lives to the core. Through national curfews and social distancing, individuals’ social lives changed and led to increased levels of stress and mental health problems. As another consequence, communication, especially among young people, has shifted to social networking sites, where particularly young adults sought help for their mental health problems. In recent years, Instagram has received recognition for its health-enhancing potentials. On this social networking site, more than 1 billion users worldwide post 500 million stories and images per day. Methods: During COVID-19, increasing mental health incidences were reported throughout the world, and have led mental health influencers to gain in relevance. The proposed study is based on a quantitative survey. In order to test how different content formats utilized by mental health influencers —motivational quotes, comics, or influencer posts—are evaluated by Instagram users, a cross-sectional quantitative study was conducted in April 2021. Data collection was based on convenience sampling. In total, 532 Austrian respondents between 16 and 34 years of age participated in the survey. Results: Overall, the content that received the most favorable evaluations were both the motivational quote (M = 4.23) and the influencer post (M = 4.12), while the comics scored lower in terms of evaluations (M = 3.72). Conclusions: Respondents’ preference of content suggests that individuals seek out content that boosts their esteem or content with a “human touch”. Explanations as to why the selected content formats were preferred over the other formats are offered alongside a future research outlook.

How Far Can the Message Go Through Online Communication

The phenomenon of information stickiness is widely seen by a declined information vitality and is hypothesised with multiple causes, but research on it is scant. Therefore, it is necessary to unmask the myth and concretise the concept. This research adopts an agent-based simulation model incorporating information accumulation, attitudinal proposition, interest, and preference for searching and matching information to determine how identified antecedents affect four defined symptoms of information stickiness in a simulated virtual community. This paper demystifies these symptoms, which are embedded in various personal, relational, and environmental settings. Some aggregate-level outcomes of consumers’ message-triggered responses emerge as an endogenous outcome of information stickiness. Analysis of data is visualised and quantified for its longitudinal changes in information acquisition, group affiliation, information growth, and the system's vitality.

Motivate me to exercise with you: The effects of social media fitness influencers on users’ intentions to engage in physical activity and the role of user gender

Objective

Social media fitness influencers are evolving into a new digital form of health communicators whom consumers might turn to for assistance with more physical activity and exercise at home, especially in the current COVID-19 crisis. Drawing from source credibility theory, social cognitive theory, protection motivation theory and literature on physical activity, physical fitness and gender, we analyse how male and female users’ evaluations of social media fitness influencers and user health-related variables impact intentions to exercise with the social media fitness influencer.

Methods

Two consecutive studies using male and female YouTube fitness influencers were carried out. Structural equation modelling was conducted to test the proposed models and estimate the path coefficients.

Results

Study 1 (N = 507) shows that the respective influencer's perceived trustworthiness, expertise and attractiveness are important for the influencer's evaluation, and that it is the perceived motivating power rather than the attitude toward the influencer that increases intentions to exercise for male and female users. Study 2 (N = 445) extends Study 1 and shows that physical fitness, training involvement with YouTube fitness videos and lower health increase behavioural intentions. A more negative body image also raises intentions to exercise, but only among female users.

Conclusion

Social media fitness influencers who are perceived as trustworthy, as experts and as attractive, can be effective for increasing men's and women's physical activity. Perceived motivating power of the influencer emerged as a key variable that predicts intentions to exercise. User health-related variables have different effects on intentions to exercise for men and women.

Factors Affecting Physicians' Credibility on Twitter When Sharing Health Information: Online Experimental Study

Background

Largely absent from research on how users appraise the credibility of professionals as sources for the information they find on social media is work investigating factors shaping credibility within a specific profession, such as physicians.

Objective

We address debates about how physicians can show their credibility on social media depending on whether they employ a formal or casual appearance in their profile picture. Using prominence-interpretation theory, we posit that formal appearance will affect perceived credibility based on users' social context-specifically, whether they have a regular health care provider.

Methods

For this experiment, we recruited 205 social media users using Amazon Mechanical Turk. We asked participants if they had a regular health care provider and then randomly assigned them to read 1 of 3 Twitter posts that varied only in the profile picture of the physician offering health advice. Next, we tasked participants with assessing the credibility of the physician and their likelihood of engaging with the tweet and the physician on Twitter. We used path analysis to assess whether participants having a regular health care provider impacted how the profile picture affected their ratings of the physician's credibility and their likelihood to engage with the tweet and physician on Twitter.

Results

We found that the profile picture of a physician posting health advice in either formal or casual attire did not elicit significant differences in credibility, with ratings comparable to those having no profile image. Among participants assigned the formal appearance condition, those with a regular provider rated the physician higher on a credibility than those without, which led to stronger intentions to engage with the tweet and physician.

Conclusions

The findings add to existing research by showing how the social context of information seeking on social media shapes the credibility of a given professional. Practical implications for professionals engaging with the public on social media and combating false information include moving past debates about casual versus formal appearances and toward identifying ways to segment audiences based on factors like their backgrounds (eg, experiences with health care providers).

Social Media Marketing Strategies of Football Clubs

Sports organisations, including football clubs, are using social media to connect with spectators. The aim of this study is to examine whether social influence on social media can increase attendance at matches. In particular, it aims to examine the effect of negative comments on consumer behaviour and how social influence differs across fans of varying levels of fandom. 89 respondents were randomly allocated to 3 groups. Respondents in the Control Group were exposed to a Facebook page of a football club without any comments while respondents in Experimental Group 1 and 2 were exposed to the same Facebook page but with additional positive and negative comments respectively. A one-way between-groups analysis of variance showed no statistical difference between the three groups on perception of quality of the players and the coaches, and intention to watch future matches. While earlier studies have shown that social influence on social media can affect consumer behaviour, this study found that social influence may be limited in affecting spectator perceptions and behaviour.
