Growing up to be fearful? Social evaluative fears during adolescence

This thesis studies the normal developmental pattern of social evaluative fears from childhood to adolescence. We have investigated age differences in self-reported social fears and physical responses during a public speaking task. In addition, youth's perceptions of speaking in public were studied through a short interview. Finally, two aspects of adolescent development are highlighted, namely resistance to peer influence and self-restraint, in the two concluding chapters. The main finding of the thesis is that social evaluative fears seem to increase with age. However, future research needs to develop more developmentally sensitive measures and further investigate the underlying processes of this increase.LEI Universiteit LeidenDevelopmental pathways of social-emotional and cognitive functioning - ou

Social Media Use, Social Media Stress, and Sleep

There are concerns that social media (SM) use and SM stress may disrupt sleep. However, evidence on both the cross-sectional and longitudinal relationships is limited. Therefore, the main aim of this study is to address this gap in the literature by examining the cross-sectional and longitudinal relationships between SM use, SM stress, and sleep (i.e., sleep latency and daytime sleepiness) in adolescents. In total, 1,441 adolescents 11–15 years, 51% boys) filled out a survey in at least one of three waves that were three to four months apart (NWave1 = 1,241; NWave2 = 1,216; NWave3 = 1,103). Cross-sectionally, we found that SM use and SM stress were positively related to sleep latency and daytime sleepiness. However, when examined together, SM use was not a significant predictor of sleep latency and daytime sleepiness above the effects of SM stress. The longitudinal findings showed that SM stress was positively related to subsequent sleep latency and daytime sleepiness, but only among girls. Our findings stress that it is important to focus on how adolescents perceive and cope with their SM use, instead of focusing on the mere frequency of SM use

Psychosomatic complaints in adolescence: Untangling the relationship between offline and online peer victimization, psychosomatic complaints and social support

Offline peer victimization has been linked to psychosomatic complaints. As peer victimization is no longer limited to adolescents’ offline relationships, it is crucial that we investigate whether online peer victimization has similar negative consequences. To date, no study systematically investigated the unique contribution of online vs. offline peer victimization on psychosomatic complaints, and the possible protective effect of social support. The current study disentangled offline and online peer victimization by distinguishing four victim types: non-victims, offline, online, and dual victims (N = 897, 9-to-18-year-olds). In addition, we assessed perceived social support from teachers, parents, friends and classmates. A main effect was found for victim type on psychosomatic complaints. Victims (offline or dual) reported more psychosomatic complaints than non-victims. Notably, online victims reported similar levels of psychosomatic complaints compared to non-victims. Furthermore, although social support from parents and classmates was related to fewer psychosomatic complaints, only limited support was found for a buffering effect of social support

Dating gone mobile: Demographic and personality-based correlates of using smartphone-based dating applications among emerging adults

Mobile dating is more common with an increasing number of smartphone applications coming to market that aim to facilitate dating. In the current study, we investigated how dating app use and motivations related to demographic identity variables (i.e. gender and sexual orientation) and personality-based variables among young adults. Nearly half of the sample used dating apps regularly, with Tinder being the most popular. Non-users were more likely to be heterosexual, high in dating anxiety, and low in sexual permissiveness than dating app users. Among app users, dating app motivations, that is, relational goal motivations (love, casual sex), intrapersonal goal motivations (self-worth validation, ease of communication), and entertainment goal motivations (thrill of excitement, trendiness), were meaningfully related to identity features, for example, sexual permissiveness was related to the casual sex motive. Our study underlines that users’ identity drives their motivations for and engagement in mobile dating. However, more research is needed to study how sexual orientation influences mobile dating
