Factors influencing continuance intention to use social network sites: The Facebook case

Social networking sites (SNS) have become one of the most popular means of online social interaction. However, few studies have examined SNS from the context of post-adoption. This study focuses on continuance usage intention toward Facebook, a popular SNS, among university students in the United Arab Emirates. We have extended the expectation–confirmation model by investigating the influence of enjoyment and subjective norms as critical factors that directly influence continuance usage intention, and added habit as a mediator between satisfaction and continuance intention. We used structural equation modeling to validate the proposed model and hypotheses. We find that perceived usefulness, satisfaction, habit, enjoyment, and subjective norms explain 54.8% of the variance in continuance intention. Furthermore, our study shows that the effect of satisfaction on continuance intention is both direct and mediated by habit. Thus, practitioners should focus on all of these factors to encourage continuance usage intention in their site’s users.     

Developing an antecedent model of knowledge sharing intention in virtual communities

This study explored the antecedent model of knowledge sharing intention in virtual communities based on social influence theory. A field survey was performed with the participation of 176 college students who were Facebook users. The results indicated that expected benefits (i.e., cognitive benefits, social integrative benefits, personal integrative benefits, and hedonic benefits) significantly and positively influenced social influence factors (i.e., group norms, social identity, and subjective norms). In addition, social influence factors (i.e., group norms, social identity, and subjective norms) significantly and positively influenced knowledge sharing intention in virtual communities. Finally, social influence factors (i.e., group norms, social identity, and subjective norms) fully mediate the effects of expected benefits (i.e., cognitive benefits, social integrative benefits, personal integrative benefits, and hedonic benefits) on knowledge sharing intention. This study identified the antecedents of knowledge sharing intention in virtual communities, and the results could be applied to areas of organization, education, and business.     

Understanding the Intention of Using Mobile Social Networking Apps Across Cultures

Understanding the user acceptance of mobile social networking apps in different cultures can provide powerful insights for managers and marketers of social networking apps to develop effective globalized and localized strategies to attract users worldwide. Following the theory of planned behavior, this study develops a research model of privacy concern (PC), privacy risk (PR), and perceived enjoyment (PE) as attitudinal beliefs, subjective norm (SN) as normative belief, and smartphone self-efficacy (SE) as control belief to understand users’ intention to use mobile social networking apps. In particular, the impact of culture was investigated, considering the user base of mobile social networking apps is distributed globally and culturally diversified, and cultural values have direct impact on behavior. The research model was validated by survey data collected from 151 participants in the U.S. and 170 participants in South Korea. The data analysis results show that perceived enjoyment and subjective norm are the most important drivers behind users’ intention to use mobile social networking apps for both countries. No significant difference was found for the effects of privacy risk and subjective norm upon users’ intention to use mobile social networking apps across cultures. Implications of the findings upon theory and practice are discussed.     

Social influence process in the acceptance of a virtual community service

This study investigates the effect of subjective norms, tendency to social comparison, and social identity on behavioral intention to use an Avatar service. Use of a virtual community service can be regarded as social behavior or a behavior affected by social factors. This study relies on the link between subjective norms and behavioral intention in the theory of reasoned action, social identity theory, and social comparison literature. The proposed model was tested using survey data with the results lending support for the proposed model. The implications from this study are expected to contribute to the literature by shedding light on the social influence process in two ways. First, this study unveils how social factors including subjective norms, social identity, and tendency to social comparison affect behavioral intention to use a specific service from virtual communities. Second, this study will aid managers and academics to further understand the social nature of customer behavior with regard to using virtual community services and thus provide insight for the development of technology driven e-commerce.

Reciprocity norms and information-sharing behavior in online consumption communities: An empirical investigation of antecedents and moderators

This study seeks a better understanding of information-sharing behavior in online consumption communities by investigating both the antecedents and moderating mechanisms of such behavior. Using self-reported data collected over two periods, along with objective behavioral data, the authors show that a reciprocity norm functions as a proximal determinant of information-sharing behavior. This norm also channels the effects of social, hedonic, and utilitarian community values on sharing behavior. The results reveal that the conversion of reciprocity norms into information-sharing behavior depends on individual and contextual conditions. These significant insights reflect the integration of consumer resource allocation theory with a reciprocity framework to establish an explanatory platform for members’ information-sharing behavior in online communities. Both theoretical and practical implications are discussed.     

Learning to Be Thoughtless: Social Norms and Individual Computation

This paper extends the literature on the evolution of norms with anagent-based modelcapturing a phenomenon that has been essentially ignored, namely thatindividual thought – orcomputing – is often inversely related to the strength of a social norm.Once a norm isentrenched, we conform thoughtlessly. In this model, agents learn how tobehave (what normto adopt), but – under a strategy I term Best Reply to Adaptive SampleEvidence – they also learnhow much to think about how to behave. How much they are thinking affects howthey behave,which – given how others behave – affects how much they think. Inshort, there is feedbackbetween the social (inter-agent) and internal (intra-agent) dynamics. Inaddition, we generate thestylized facts regarding the spatio-temporal evolution of norms: localconformity, global diversity,and punctuated equilibria.     

Understanding Chinese users’ continuance intention toward online social networks: an integrative theoretical model

This study explores users’ continuance intention in online social networks by synthesizing Bhattacherjee’s IS continuance theory with flow theory, social capital theory, and the unified theory of acceptance and use of technology (UTAUT) to consider the special hedonic, social and utilitarian factors in the online social network environment. The integrated model was empirically tested with 320 online social network users in China. The results indicated that continuance intention was explained substantially by all hypothesized antecedents including perceived enjoyment, perceived usefulness, usage satisfaction, effort expectancy, social influence, tie strength, shared norms and trust. Based on the research findings, we offer discussions of both theoretical and practical implications.     

Decreasing the problematic use of an information system: An empirical investigation of smartphone game players

Based on protection motivation theory, this study aims to identify factors that influence the intention to decrease problematic smartphone game use, including the effects of a gaming habit and subjective norms. The research model is tested with a scenario‐based survey method. Players' perceived threat refers to the negative consequences (eg, reduced performance or social isolation) that are caused by problematic smartphone game use. The findings indicate that under high fear appeals, threat appraisal creates fearful emotions about suffering from the negative consequences, which further reduces the gaming habit and activates the intention to decrease use. Self‐efficacy in decreasing game playing, the response efficacy of decreasing usage in avoiding the threat and subjective norms effectively promote users' intention to decrease use. Moreover, response costs reduce the intention to decrease use. The findings provide insights into how to activate users' intention to decrease problematic use, and the resulting implications are discussed.     

On social Web sites

Today hundreds of millions of Internet users are using thousands of social Web sites to stay connected with their friends, discover new “friends,” and to share user-created contents, such as photos, videos, social bookmarks, and blogs. There are so many social Web sites, and their features are evolving rapidly. There is controversy about the benefits of these sites, and there are social issues these sites have given rise to. There are lots of press articles, Wikipedia articles, and blogs—in varying degrees of authoritativeness, clarity and accuracy—about some of the social Web sites, uses of the sites, and some social problems, and business challenges faced by the sites. In this paper, we attempt to organize the status, uses, and issues of social Web sites into a comprehensive framework for discussing, understanding, using, building, and forecasting the future of social Web sites.     

The Effects of Social Influence on User Acceptance of Online Social Networks

With the proliferation of online social networks, understanding how and why individuals adopt and use these networks can help managers and marketers to design better methods and approaches toward engaging their users. The purpose of this study is to investigate the determinants of user acceptance of online social networks, with particular attention given to the effects of social influence. A research model was developed by incorporating two variables of social influence, subjective norm and critical mass, into an enhanced version of the Technology Acceptance Model, specifically to address issues related to online social networks. The model was empirically evaluated using survey data collected from 269 subjects about their perceptions of online social networks. The results reveal that both subjective norm and critical mass significantly affect perceived usefulness, which further affects users' usage intention, and perceived ease of use affects the usage intention indirectly through perceived usefulness. The implications of this study on theory and practice are discussed.     

Personality and social characteristics of Facebook non-users and frequent users

Facebook is currently the largest social networking website with an estimated one billion of monthly active users in 2012. While most of the prior research has explored characteristics of Facebook users, less is known about the characteristics of individuals who do not use Facebook. The current study examined personality and social factors that might influence the decision to use Facebook and explored differences between Facebook non-users and frequent users. Online questionnaires examining levels of trust and self-disclosure, number of intimate friendships, peer usage of Facebook and scores on overt and covert narcissism were used for the purpose of the study. The results showed that non-users and frequent users differed on several social and personality characteristics. Facebook non-users had lower tendency to self-disclose, fewer peers participating in the social network and higher covert narcissistic traits. Frequent Facebook users scored higher on overt narcissism and reported more intimate friendships than non-users, indicating that close friendships might actually extend to social networks and contribute to a feeling of closeness and intimacy between friends in both an online and offline context.     

How social influence affects we-intention to use instant messaging: The moderating effect of usage experience

With the advent of Web 2.0, the business world is fast changing its way of communicating and collaborating. In this study, we regarded the use of instant messaging in team collaboration as a social behavior and examined the changing roles of social influence processes in the formation of usage we-intention (i.e. social intention). Building on the belief-desire-intention model and the social influence theory, an integrated model was developed and empirically tested using survey data collected from 482 students. The results demonstrated that desire partially mediates the effects of group norm and social identity on we-intention to use. In addition, the effect of group norm is more significant for users with lower usage experience, whereas the effect of social identity is more significant for users with higher usage experience. We believe this study provides several important implications for both research and practice.     

Personality traits and knowledge sharing in online communities

Adopting diffusion theory and the concept of social value orientation, the effects of personality traits on knowledge sharing in a virtual open content community are investigated. In addition to the main effects of personality, it was hypothesized that intrinsic motivations would moderate the effects on knowledge sharing. A sample of N = 256 active users of Wikipedia provided measures of personality, motivation, and knowledge sharing. Latent regression analyses support the notion that authorship of Wikipedia is associated with higher levels of trendsetting and a prosocial value orientation. Moreover, moderation analyses demonstrate that the effect of the latter is moderated by individual differences in motivations to write. Differences with regard to opinion leadership could not be confirmed.     

Motivations of Wikipedia content contributors

Rapidly developing web technologies have increased the prevalence of user-generated Internet content. Of the many websites with user-generated content on the Internet, one of the most renowned is Wikipedia, which is the largest multilingual free-content encyclopedia written by users collaboratively. Nevertheless, although contributing to Wikipedia takes time and knowledge, contributors are rarely compensated. As a result, there is a need to understand why individuals share their knowledge in Wikipedia. The aim of this study was to evaluate the effects of both conventional and self concept-based motivation on individual willingness to share knowledge in Wikipedia. After performing an online questionnaire survey, SEM was applied to assess the proposed model and hypotheses. The analytical results showed that internal self-concept motivation is the key motivation for knowledge sharing on Wikipedia.     

Social network use and personality

Studies have shown a connection between the individual personality of the user and the way he or she behaves on line. Today many millions of people around the world are connected by being members of various Internet social networks. Ross et al. (2009) studied the connection between the personality of the individual users and their behavior on a social network. They based their study on the self-reports of users of Facebook, one of the most popular social networks, and measured five personality factors using the NEO-PI-R (Costa & McCrae, 1992) questionnaire. They found that while there was a connection between the personalities of surfers and their behavior on Facebook, it was not strong. This study is based on that of Ross et al. (2009), but in our study the self-reports of subjects, were replaced by more objective criteria, measurements of the user-information upload on Facebook. A strong connection was found between personality and Facebook behavior. Implications of the results are discussed.     

The moderating effects of gender on e-commerce systems adoption factors: An empirical investigation

For e-commerce designers and human–computer interaction researchers, electronic commerce (e-commerce) systems adoption factors and the moderating effects of gender are important topics. Even though there are research endeavors to explain e-commerce systems adoption, one of the main questions to be answered is regarding the normative and affective factors based on the theory of reasoned action and self-determination theory. In this paper, social norms, perceived enjoyment, and their relationships to intention to adopt an e-commerce system are tested (n = 322). Furthermore, the moderating effects of gender are tested based on the sociolinguistic literature. As expected, the influence of social norms is stronger in the female group while the influence of enjoyment is stronger in the male group. Theoretical and practical implications of these findings are discussed in the paper.
