Ever since the emergence of social networking sites (SNSs), it has remained a question without a conclusive answer whether SNSs make people more or less lonely. To achieve a better understanding, researchers need to move beyond studying overall SNS usage. In addition, it is necessary to attend to personal attributes as potential moderators. Given that SNSs provide rich opportunities for social comparison, one highly relevant personality trait would be social comparison orientation (SCO), and yet this personal attribute has been understudied in social media research. Drawing on literature of psychosocial implications of social media use and SCO, this study explored associations between loneliness and various Instagram activities and the role of SCO in this context. A total of 208 undergraduate students attending a U.S. mid-southern university completed a self-report survey (M = 19.43, SD = 1.35; 78 percent female; 57 percent White). Findings showed that Instagram interaction and Instagram browsing were both related to lower loneliness, whereas Instagram broadcasting was associated with higher loneliness. SCO moderated the relationship between Instagram use and loneliness such that Instagram interaction was related to lower loneliness only for low SCO users. The results revealed implications for healthy SNS use and the importance of including personality traits and specific SNS use patterns to disentangle the role of SNS use in psychological well-being.

Previous studies have confirmed that Facebook, the leading social networking site among young people, facilitates social connections among college students, but the specific activities and motives that foster social adjustment remain unclear. This study examined associations between patterns of Facebook activity, motives for using Facebook, and late adolescents' social adjustment to the college environment. Anonymous self-report survey data from 193 mostly European American students (M age = 20.32; 54 % female) attending a major Midwestern university indicated that motives and activity patterns were associated directly with social adjustment, but the association between one activity, status updating, and social adjustment also was moderated by the motive of relationship maintenance. Findings provide a more comprehensive portrait of how Facebook use may foster or inhibit social adjustment in college.

Self-presentation, a central element of young people's identity development, now extends from face-to-face contexts to social networking sites. Online self-presentation may change when youth transition to college, faced with the need to reclaim or redefine themselves in the new environment. Drawing on theories of self-presentation and self development, this study explores changes in youth's online self-presentation during their transition to a residential college. It also examines associations between online self-presentation and students' self-esteem and self-concept clarity. We surveyed 218 college freshmen (M age = 18.07; 64 % female, 79 % White) at the beginning and again at the end of their first semester. Freshmen's Facebook self-presentation became less restricted later in the semester. Broad, deep, positive, and authentic Facebook self-presentation was positively associated with perceived support from the audience, which contributed to higher self-esteem contemporaneously, though not longitudinally. Intentional Facebook self-presentation engaged students in self-reflection, which was related to lower self-concept clarity concurrently but higher self-esteem longitudinally. Findings clarified the paths from multifaceted online self-presentation to self development via interpersonal and intrapersonal processes during college transition.

Mobile games such as Pokémon Go have become a major form of entertainment, and yet little is known about why people play the games and how their motives associate with well-being. Although literature on motives for playing video and online games is informative, the findings may not reflect the full spectrum of mobile gaming motives due to some unique affordances of mobile games (e.g., mobility). To catch up with the evolving gaming context, a popular mobile game, Pokémon Go, was taken as an example to explore individuals' mobile gaming motives. A Pokémon Go Motive Scale was developed. Seven motives were identified through factor analyses based on survey data from 262 Pokémon Go players (45 percent women; M = 30.71, standard deviation = 7.77): Exercise, Fun, Escapism, Nostalgia, Friendship Maintenance, Relationship Initiation, and Achievement. Both Fun and Friendship Maintenance were positive correlates of well-being, whereas Escapism and Nostalgia were negative correlates. Relationship Initiation was associated with both better and poorer well-being. Implications of the findings are discussed.

Introduction: Social media provide a convenient platform for social comparison, an activity that should play an important role in youth's identity development at the transition to college. Yet, the identity implications of online social comparison have not been thoroughly explored. Drawing on the theories of social comparison, introspective processes, and identity distress, we examined a dual-path model. The paths from two types of social media social comparison (i.e., comparison of ability and comparison of opinion) to two introspective processes (i.e., rumination and reflection) and finally to identity distress were tested. Methods: Short-term longitudinal survey data were collected from 219 college freshmen at a state university in the United States of America (M age = 18.29, S.D. = 0.75; 74% female; 41% White, 38% Black). Results: Social comparison of ability on social media had a positive association with concurrent rumination, which predicted higher identity distress. In contrast, social comparison of opinion on social media had a positive relationship with concurrent reflection, which, however, did not predict identity distress. Conclusion:Results indicate that different types of online social comparison yield distinct implications for young people's identity development. Largely, the study reaffirms the recently rising call for distinguishing the competition-based social comparison of ability from the information-based social comparison of opinion. At the same time, the study expands current knowledge of why these forms of social comparison may lead to differential outcomes, namely through the type of introspection they induce.Identity development is a major developmental task for adolescents and emerging adults (Arnett, 2014;Erikson, 1968). The task seems particularly challenging in modern society, where major socio-cultural changes make it a more complicated issue . For instance, scholars have discussed how globalization and economic recessions may require more time for identity exploration and delay youth's identity commitment and integration (Arnett, 2002;Sica, Sestito, & Ragozini, 2014). This study turned to the growth of social media as another contributor to the complexity of identity negotiation in the digital age. Specifically, it explored the identity implications of a widely experienced behavior on social media-social comparison, the process of comparing oneself with others as a way to understand and evaluate oneself (Festinger, 1954).Identity development in the social media context is typically studied through the lens of online self-presentation (e.g., Manago,
