Mobile Dating Applications (MDAs) are integral to young adults' lives, serving as a platform for romantic and sexual self-presentation during the search for potential partners. Despite its potential link to adverse outcomes including body shame, the prevalence of sexualized self-presentation remains understudied. This pre-registered linkage study addresses this gap by documenting sexualized self-presentation while considering individual differences related to gender, sexual orientation, and body image.

Mobile dating applications (MDAs) have become commonly used tools to seek out dating and sexual partners online. The current review aimed to systematically synthesize empirical findings in 72 quantitative studies on mobile dating, published in ISI-ranked journals between 2014 and 2020. This review focused on summarizing different approaches toward mobile dating, identity features of quantitative research on mobile dating, and hypothesized antecedents and outcomes of mobile dating.

Despite voiced concerns about sexual online risk behaviors related to mobile dating, little is known about the relation between mobile dating and sexting. The current cross-sectional study (N = 286) examined the relations between the use of geo-social dating apps and emerging adults' willingness to sext with a dating app match. By drawing on the prototype willingness model, both a reasoned path and a social reaction path are proposed to explain this link.

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.

Objectives: The aims of this study were (1) to investigate the prevalence and development of both online (OnSRB) and offline sexual risk behavior (OffSRB) in adolescence, (2) to establish whether OnSRBs and OffSRBs are related, and (3) to identify risk factors that determine problematic pathways of OnSRB and OffSRB.

Methods: A 4-wave longitudinal study with 1762 Dutch adolescents aged 12 to 18 was conducted (mean age, T1 = 14.52, 49% girls).

Purpose: This study investigated the development and consequences of off-line and online victimization during adolescence. We examined the number and shapes of off-line and online victimization trajectories, the relationship between trajectories of off-line and online victimization, and their effect on life satisfaction.

Methods: A four-wave panel study with 6-month time intervals was conducted among a representative sample of Dutch adolescents aged 12-17 years (N = 1,762).

Although there is developmental research on the prevalence of offline self-disclosure in pre-adolescence and adolescence, it is still unknown (a) how boys' and girls'online self-disclosure develops in this period and (b) how online and offline self-disclosure interact with each other. We formulated three hypotheses to explain the possible interaction between online and offline self-disclosure: the displacement, the rich-get-richer, and the rehearsal hypothesis. We surveyed 690 pre-adolescents and adolescents (10-17 years) at three time points with half-year intervals in between.

Common folklore seems to suggest that adolescents are particularly susceptible to peer influence. However, from the literature the exact age differences in susceptibility to peer influence remain unclear. The current study's main focus was to chart the development of general susceptibility to peer pressure in a community sample of 10-18 year olds (N =464) with the recently developed Resistance to Peer Influence Scale (RPI).
