Benefits of a Negative Post: Effects of Computer-Mediated Venting on Relationship Maintenance

Despite abundant literature on the benefits of using social networking sites to map user behavior patterns, limited research exists regarding the effects of negative expression via these sites. Responding to this need, the purpose of this study is to address gaps, in both the relationship maintenance and the catharsis theory literature, by examining the connections among Facebook use, disclosure of negative feelings on Facebook (venting), and relationship maintenance behaviors. A survey study with college students from a university located in southeast United States (N = 341) was conducted, and the results from logistic regression analyses indicate that Facebook usage and level of perceived stress are significant predictors for individual’s venting behaviors. Further, the results indicated that venting negative feelings on Facebook mediates the effect of an individual’s perceived stress on his/her online relationship maintenance behaviors.     

Facebook use and academic performance among college students: A mixed-methods study with a multi-ethnic sample

This paper uses a mixed-methods approach to examine the relation between online academic disclosure and academic performance. A multi-ethnic sample of college students (N = 261; male = 66; female = 195; M age ≈ 22 years) responded to open-ended questions about their Facebook use. Thematic analysis revealed that over 14% of the Facebook wall posts/status updates (N = 714) contained academic themes; positive states were more frequent than negative and neutral states and students with lower GPAs expressed negative states more often. A path analysis suggested that academic performance may determine college students’ Facebook use, rather than the reverse. Implications for student support services are discussed.     

Teens’ concern for privacy when using social networking sites: An analysis of socialization agents and relationships with privacy-protecting behaviors

U.S. teens are spending substantial time on social networking sites (SNSs). Yet, only a few studies have documented teens’ privacy-protecting behaviors on SNSs. Using data of Facebook teen users and their parents in the U.S. from the Pew Internet’s Teens & Privacy Management Survey (N = 622), this study investigated the socialization agents of teens’ level of online privacy concern, and the relationship between teens’ level of online privacy concern and their privacy-protecting behaviors on SNSs. Based on path analysis results, this study identified parents and SNS use as the two significant socialization agents. In particular, this study revealed the role of parents’ privacy concern and the role of SNS use in motivating teens to increase online privacy concern, which, in turn, drives teens to adopt various privacy-setting strategies on SNSs and to set their Facebook profiles to private. Implications for policymakers and educators were discussed.     

Posting,commenting, and tagging: Effects of sharing news stories on Facebook

Social networking sites such as Facebook provide new ways of sharing news stories that allow users to act as opinion leaders in their networks, encourage discussion, and potentially increase their involvement in current events. This study identifies the particular features of Facebook that facilitate the discussion of news and tests their effects on involvement and feelings of influence. Participants (N = 265) in a 3 (Broadcast level: news feed vs. wall post vs. direct message) × 3 (Elaboration: opinion vs. question vs. no comment) × 2 (Involving-friends: tag vs. no tag) between-subjects factorial experiment were randomly assigned to share a story from a news website on Facebook. Results show that user involvement in the news content depends on the social affordances of the site, particularly those that allow for audience customization and those that drive network feedback. Asking the network’s opinions and targeting specific friends led to greater involvement in the news content. Discussion through comments led to a greater sense of influence and greater involvement for those sharing the news story. These findings highlight the importance of encouraging individuals to act as sources of information in their networks to drive engagement in current events in the changing news landscape.     

Psychological predictors of addictive social networking sites use: The case of Serbia

The popularity of social networking sites (SNS) changed to a great extent not only media environment, but also everyday life activities of modern humans. Despite their obvious benefits in terms of communication, there is evidence of addictive tendencies in SNS use. The study examined psychological and socio-demographic predictors of these addictive tendencies in Serbian SNS users drawn from a representative sample (N = 2014), having in mind that Serbia has Facebook penetration rate over European average. Results indicate a low incidence of self-reported addictive tendencies, with some individual differences worth addressing. We developed and tested exhaustive model that included three sets of predictors (socio-demographic, psychological and exposure to traditional media), as well as restrictive models that systematically excluded group by group. Path analysis revealed that psychological traits were stronger predictors than socio-demographic ones: people with lower self-esteem, lower general self-efficacy and higher introversion were more likely to report addictive SNS use. Although our results in general support the so called “social compensation hypothesis”, it can be due to the focus on addictive tendencies instead of other indicators of SNS use.     

Facebook or Renren? A comparative study of social networking site use and social capital among Chinese international students in the United States

Social networking sites (SNSs) are important tools for college students to maintain and develop social capital. Yet, few studies on the social implications of using SNSs have focused on international students and their use of different social media platforms for social capital. This study aims to fill this gap by examining the implications of using host country and home country SNSs for social capital among Chinese international students in the United States. A survey of Chinese international students at a large public university (N = 210) reveals that both Facebook and Renren use are positively associated with bridging social capital but not with bonding social capital. Facebook use has a stronger relationship with bridging social capital than does Renren use. Yet, only Renren use has a significant and positive relationship with maintaining home country social capital. These results have practical implications for international students to develop different types of social capital through different social media platforms.     

Who puts the best “face” forward on Facebook?: Positive self-presentation in online social networking and the role of self-consciousness,actual-to-total Friends ratio,and culture

The present research investigated how individual, interpersonal, and cultural variables influence positive self-presentation in online social networking. In particular, we examined the role of self-consciousness, actual-to-total Friends ratio, and culture in positive self-presentation on Facebook. A cross-sectional survey was conducted with college-age participants in the United States (n = 183) and South Korea (n = 137). Results showed that self-consciousness (public vs. private) and actual-to-total Friends ratio were not significantly associated with positive self-presentation on Facebook; however, culture showed a statistically significant association with positive self-presentation on Facebook, with the U.S. participants engaging in positive self-presentation on Facebook to a greater extent than the South Korean participants. More interestingly, culture significantly moderated the relationship between public self-consciousness and positive self-presentation as well as the relationship between actual-to-total Friends ratio and positive self-presentation. Specifically, positive self-presentation showed a significant positive association with public self-consciousness and a significant negative association with actual-to-total Friends ratio only among the South Korean participants and not among the U.S. participants. Theoretical and practical implications for understanding cross-cultural differences in self-presentation behaviors on social network sites were discussed.     

Exploring depression and problematic internet use among college females: A multisite study

ObjectiveThe purpose of this study was to assess associations between depression and problematic internet use (PIU) among female college students, and determine whether Internet use time moderates this relationship.MethodThis cross-sectional survey included 265 female college students from four U.S. universities. Students completed the Patient Health Questionnaire-9 (PHQ-9), the Problematic and Risky Internet Use Screening Scale (PRIUSS) and self-reported daily Internet use. Analyses included multivariate analysis of variance and Poisson regression.ResultsParticipants reported mean age of 20.2 years (SD = 1.7) and were 84.9% Caucasian. The mean PHQ-9 score was 5.4 (SD = 4.6); the mean PRIUSS score was 16.4 (SD = 11.1). Participants’ risk for PIU increased by 27% with each additional 30 min spent online using a computer (RR = 1.27, 95% CI: 1.14–1.42, p < .0001). Risk for PIU was significantly increased among those who met criteria for severe depression (RR = 8.16 95% CI: 4.27–15.6, p < .0001). The PHQ-9 items describing trouble concentrating, psychomotor dysregulation and suicidal ideation were most strongly associated with PIU risk.ConclusionsThe positive relationship between depression and PIU among female college students supports screening for both conditions, particularly among students reporting particular depression symptoms.     

Does Facebook make you lonely?: A meta analysis

This meta-analysis explores the relationship between Facebook use and loneliness. Examination of the literature containing quantitative measurements of both Facebook use and loneliness, including close variations of the definition of loneliness, produced a sample of 18 research effects (N = 8798) for review. This study asks two main questions: (1) Does using Facebook increase or decrease loneliness?; and (2) What causes what?: Does Facebook make its users lonely (or less lonely), or do lonely people (or less lonely people) use Facebook? First, researchers observed a significant overall average effect in the positive relationship between Facebook use and loneliness. Researchers also point to measurements of Facebook use as well as measurements of loneliness (and its variations) as possible moderating features or sources of variability in the relationship. Testing the relationship between Facebook use and loneliness in the context of two causal models revealed that (a) the first model outlining a path from elements of loneliness to Facebook use was not an adequate explanation of the data; whereas, (b) testing the relationship for a path in the second model from elements of Facebook use to loneliness showed results consistent with the data.     

Factors involved in associations between Facebook use and college adjustment: Social competence,perceived usefulness,and use patterns

Although previous research has investigated widespread use of social media, especially Facebook, by youth attending college, the conditions under which these media foster adjustment to college remain unclear. This study tested a model illuminating pathways linking social competence to college adjustment via students’ perceptions about the usefulness of Facebook and ways in which they used the medium. Self-report survey data from 321 college students (M age = 20.09; 58% female; 84% Caucasian) attending a major Midwestern university supported the proposed model, indicating that higher social competence could foster or impede college adjustment, depending upon how it was related to beliefs about the usefulness of different Facebook functions and how these perceptions, in turn, were associated with patterns of Facebook use. Findings underscore the importance of considering connections among personal attributes, perception of media effectiveness, and media behaviors in assessing the implications of social media for users’ psychosocial well-being.     

Remote sensing of canopy light use efficiency in temperate and boreal forests of North America using MODIS imagery

Light use efficiency (LUE) is an important variable characterizing plant eco-physiological functions and refers to the efficiency at which absorbed solar radiation is converted into photosynthates. The estimation of LUE at regional to global scales would be a significant advantage for global carbon cycle research. Traditional methods for canopy level LUE determination require meteorological inputs which cannot be easily obtained by remote sensing. Here we propose a new algorithm that incorporates the enhanced vegetation index (EVI) and a modified form of land surface temperature (T_m) for the estimation of monthly forest LUE based on Moderate Resolution Imaging Spectroradiometer (MODIS) imagery. Results demonstrate that a model based on EVI × T_m parameterized from ten forest sites can provide reasonable estimates of monthly LUE for temperate and boreal forest ecosystems in North America with an R² of 0.51 (p < 0.001) for the overall dataset. The regression coefficients (a, b) of the LUE–EVI × T_m correlation for these ten sites have been found to be closely correlated with the average EVI (EVI_ave, R² = 0.68, p = 0.003) and the minimum land surface temperature (LST_min, R² = 0.81, p = 0.009), providing a possible approach for model calibration. The calibrated model shows comparably good estimates of LUE for another ten independent forest ecosystems with an overall root mean square error (RMSE) of 0.055 g C per mol photosynthetically active radiation. These results are especially important for the evergreen species due to their limited variability in canopy greenness. The usefulness of this new LUE algorithm is further validated for the estimation of gross primary production (GPP) at these sites with an RMSE of 37.6 g C m^? 2 month^? 1 for all observations, which reflects a 28% improvement over the standard MODIS GPP products. These analyses should be helpful in the further development of ecosystem remote sensing methods and improving our understanding of the responses of various ecosystems to climate change.     

Problematic Internet use: Functions of use,cognitive absorption,and depression

Although researchers have studied problematic Internet use for almost a decade, there is a dearth of quantitative models to describe this phenomenon. We aimed to create a structural equation model by which we explored the extent to which the functions of the Internet use, cognitive absorption, and depression affected and explained an individual’s problematic Internet use. In 2011 and 2012 years, 244 high school students (117 boys and 127 girls) participated in this study to complete the Problematic Internet Use Scale, the Cognitive Absorption Scale, the Beck Depression Inventory, and the Internet Use Function Questionnaire. We found that the students’ functions of Internet use, cognitive absorption, and depression explained the problematic Internet use to some extent.     

“It’s Not Who You Know,but Who You Add:” An investigation into the differential impact of friend adding and self-disclosure on interpersonal perceptions on Facebook

This research seeks to understand how people perceive and respond to structural factors and different types of disclosure on Facebook when evaluating the profile of someone they have never met offline. Using a 2 × 3 × 2 between-subjects experimental design, this research explored the relationship between friend adding (add; no add), levels of self-disclosure (low, medium, high), and sex of the Facebook profile owner (male; female) on feelings of interpersonal liking, future behavioral intentions to interact, and homophily. Results indicated that friend adding and higher levels of self-disclosure led to greater feelings of interpersonal liking and homophily amongst both male and female participants. In addition, males tended to view other male profiles with moderate amounts of disclosure and female profiles with the highest amount of disclosure most favorably. Theoretical and practical implications are discussed.     

The relationship between cell phone use,academic performance,anxiety, and Satisfaction with Life in college students

While functional differences between today’s cell phones and traditional computers are becoming less clear, one difference remains plain – cell phones are almost always on-hand and allow users to connect with an array of services and networks at almost any time and any place. The Pew Center’s Internet and American Life Project suggests that college students are the most rapid adopters of cell phone technology and research is emerging which suggests high frequency cell phone use may be influencing their health and behavior. Thus, we investigated the relationships between total cell phone use (N = 496) and texting (N = 490) on Satisfaction with Life (SWL) in a large sample of college students. It was hypothesized that the relationship would be mediated by Academic Performance (GPA) and anxiety. Two separate path models indicated that the cell phone use and texting models had good overall fit. Cell phone use/texting was negatively related to GPA and positively related to anxiety; in turn, GPA was positively related to SWL while anxiety was negatively related to SWL. These findings add to the debate about student cell phone use, and how increased use may negatively impact academic performance, mental health, and subjective well-being or happiness.     

An experimental investigation of the influence of agentic and communal Facebook use on grandiose narcissism

Does activity on a social networking site (e.g., Facebook) increase grandiose narcissism? It was hypothesized that the type of activity (agentic vs. communal) might make a difference. In the first experiment, 88 males were randomly assigned to one of three computer activity conditions (agentic Facebook activity, communal Facebook activity, control computer activity). In the second experiment a larger and more diverse sample (N = 218) engaged in agentic, communal, or control activities either on a computer or not, in order to assess the impact of medium as well as thinking type. In both experiments, self-reported daily Facebook activity was correlated with narcissism. However, the experimental manipulation of agentic vs. communal Facebook use did not significantly increase state narcissism, as indicated by synthesizing the findings of the two experiments. The findings cast doubt on the notion that social networking site use promotes narcissism, though additional research on the topic is warranted.     

Social network site use,mobile personal talk and social capital among teenagers

Social network sites (SNSs) and mobile phones are becoming increasingly important in teenagers’ lives. Using data collected from a nationally representative survey (N = 800), this study explores the variation of social capital by SNS adoption, different SNS activities, and mobile personal talk among teenagers. The results indicate that SNS adoption and mobile personal talk can not only enhance teenagers’ close ties with friends, but also jointly promote teenagers’ civic engagement. Among SNS users, mobile personal talk also increase teens’ network capital. Different SNS activities such as commenting on friend’s Facebook pictures and joining Facebook groups have different relationships with social capital, and such relationships are moderated by mobile personal talk.     

Knowledge sharing and social media: Altruism,perceived online attachment motivation,and perceived online relationship commitment

Social media, such as Facebook and Twitter, have become extremely popular. Facebook, for example, has more than a billion registered users and thousands of millions of units of information are shared every day, including short phrases, articles, photos, and audio and video clips. However, only a tiny proportion of these sharing units trigger any type of knowledge exchange that is ultimately beneficial to the users. This study draws on the theory of belonging and the intrinsic motivation of altruism to explore the factors contributing to knowledge sharing behavior. Using a survey of 299 high school students applying for university after the release of the public examination results, we find that perceived online attachment motivation (β = 0.31, p < 0.001) and perceived online relationship commitment (β = 0.49, p < 0.001) have positive, direct, and significant effects on online knowledge sharing (R² 0.568). Moreover, when introduced into the model, altruism has a direct and significant effect on online knowledge sharing (β = 0.46, p < 0.001) and the total variance explained by the extended model increases to 64.9%. The implications of the findings are discussed.     

Depression,loneliness and Internet addiction: How important is low self-control?

This study aimed to explore both the direct and indirect relationships between depression, loneliness, low self-control, and Internet addiction in a sample of Turkish youth, based on a cognitive-behavioral model of generalized problematic Internet use. Data for the present study were collected from 648 undergraduate students with a mean age of 22.46 years (SD = 2.45). Participants completed scales for depression, loneliness, self-control and Internet addiction. Structural equation modeling was used to test the model in which depression and loneliness predicted Internet addiction through low self-control. The findings revealed that of the two factors, only loneliness was related to Internet addiction through low self-control. The results are discussed in terms of the cognitive-behavioral model of generalized problematic Internet use, and implications for practice are considered.     

Machiavellianism,self-monitoring,self-promotion and relational aggression on Facebook

Machiavellianism is a personality trait characterized by cynicism, emotional detachment and a willingness to manipulate others. Research investigating the behavior of Machiavellian men and women has focused on its influence in offline relationships. The popularity of social networking sites suggests that it is also important to consider the interactions of Machiavellian men and women in this context as well. Men (N = 54) and women (N = 189) completed questionnaires assessing Machiavellianism, self-monitoring, self-promotion and relational aggression. Analyses revealed that women who were high in Machiavellianism engaged in more dishonest self-promotion and relational aggression towards a close friend on Facebook whilst males with high levels of Machiavellianism engaged in more self-promoting behavior. In addition, both men and women high in Machiavellianism engaged in more self-monitoring. The findings demonstrate the importance of considering the influence of personality on online behavior and associated gender differences.     

Pathological video game playing in Spanish and British adolescents: Towards the exploration of Internet Gaming Disorder symptomatology

Research into problematic video gaming has increased greatly over the last decade and many screening instruments have been developed to identify such behaviour. This study re-examined the Problematic Videogame Playing [PVP] Scale. The objectives of the study were to (i) examine its psychometric properties in two European countries, (ii) estimate the prevalence of potential pathological gaming among adolescents in both countries, and (iii) assess the classification accuracy of the PVP Scale based on its symptomatology as a way of exploring its relationship with both the behavioural component model of addiction and the proposed Internet Gaming Disorder. The data were collected via a survey administered to 2356 adolescents aged between 11 and 18 years from Spain (n = 1132) and Great Britain (n = 1224). Results indicated that the reliability of both versions was adequate, and the factorial and construct validity were good. Findings also showed that the prevalence of pathological gamers estimated with a rigorous cut-off point was 7.7% for Spanish and 14.6% for British adolescents. The scale showed adequate sensitivity, specificity and classification accuracy in both countries, and was able to differentiate between social and potential pathological gamers, and from their addictive symptomatology. The implications of these findings are discussed.
