Passive social networking site use and well-being: The mediating roles of social comparison and the fear of missing out. AbstractPassively browsing social networking sites (SNSs) correlates with poorer well-being (Verduyn, Ybarra, Résibois, Jonides, & Kross, 2017). However, less research has been conducted that fully examines what factors may mediate this association. In particular, both online social comparison and the fear of missing out (FoMO) may play roles in how passive SNS browsing relates to depressive symptoms and self-perceptions. The current study adds to the literature by investigating how passive use relates to these outcomes through social comparison and FoMO. For an ethnically diverse sample of college students (N = 717, Mage = 21.47, SDage = 4.64, 69% female), passively using SNSs positively predicted social comparison, which was positively related to FoMO, which in turn positively predicted depressive symptoms, and negatively predicted global self-worth, self-perceived physical appearance, and self-perceived social acceptance. These findings suggest that social comparison and FoMO play a role in the link between passive SNS use, depressive symptoms, and self-perceptions, and that FoMO could result from online social comparison.

Co-construction theory suggests adolescents use digital communication to address developmental challenges. For a sample of 214 ethnically diverse adolescents, this research used direct observation to investigate the frequency, content, and timing of texting with parents, peers, and romantic partners through grades 9-12. Analyses showed that texting frequency follows a curvilinear trajectory, peaking in eleventh grade. Adolescents discussed a range of topics, predominantly with peers. Communication with parents was less frequent, but consistent over time. Approximately 45-65% of adolescents communicated with romantic partners, texting heavily and about topics similar to those discussed with peers. Texting may help adolescents navigate key developmental challenges of adolescence-the establishment of autonomy, intimate peer relationships, romantic relationships, and self-identity.

Social networking sites (SNSs) may be transforming young people's social experiences, and browsing SNSs in particular may harm psychological well-being. However, browsing different types of SNS profiles may differentially relate to psychological well-being. In a large and ethnically diverse sample of emerging adults (N = 405), this experimental study examined changes in state affect and self-perceptions after browsing one of three different types of profiles on Instagram: an acquaintance, an influencer, or one's own profile. Moreover, this study investigated how individual characteristics may moderate relations between browsing and well-being, by exploring feedback seeking behaviors and the fear of missing out. Browsing one's own Instagram profile led to positive changes in psychological well-being, whereas browsing the profile of either an acquaintance or an Instagram influencer led to negative changes in psychological well-being. Many observed effects, especially those found for the acquaintance and influencer conditions, were moderated by participants' dispositional levels of the fear of missing out and feedback seeking, in which effects were primarily observed for those higher in these characteristics. Findings suggest that SNSs may have positive or negative effects on well-being depending on who is online and what those individuals are browsing.

The past decade saw a sharp increase in the use of smartphones and digital communication platforms. This manuscript reviews advancements in the study of digital communication and adolescent development over the last decade. We highlight theoretical models that seek to explain the power of digital media in adolescents’ lives. We then examine research conducted over the last decade on five aspects of digital media: (1) potential to contribute to adolescent development, (2) associations with mental health, (3) differential impact of active versus passive social media use, (4) cyberbullying, and (5) sexting. We conclude with a discussion of potential opportunities and challenges for studying the role of digital communication in adolescents’ development during the coming decade.
