Changing or stable? The effects of adolescents' social media use on psychosocial functioning.

To better understand the effects of social media use on adolescents' psychosocial functioning, this study examined the temporal stability of social media effects across two separate 3-week experience sampling methodology (ESM) studies conducted 6 months apart in 2019 and 2020. Participants were 297 adolescents (M = 14.1 years, SD = 0.

Parent-adolescent communication in a digital world: A 100-day diary study.

Digital technology enables parents and adolescents to communicate anywhere and anytime. Knowledge of parent-adolescent online communication, however, is mainly based on cross-sectional studies. In this preregistered 100-day diary study, 479 adolescents (M = 15.

Development, validity, and reliability of the parent-adolescent communication about adolescents' social media use scale (PACAS).

Adolescents spend a substantial portion of their time using social media. Yet, there is a lack of understanding regarding how often parents and adolescents communicate about this social media use. To address this gap, we developed the Parent-Adolescent Communication about Adolescents' Social Media Use Scale (PACAS).

Explaining variation in adolescents' social media-related distraction: The role of social connectivity and disconnectivity factors.

Social media are often believed to distract adolescents' attention. While existing research has shown that some adolescents experience more social media-related distraction than others, the explanations for these differences remain largely unknown. Based on Self-Determination Theory, this preregistered study investigated two social connectivity factors (fear of missing out [FoMO] and friendship accessibility expectations) and two disconnectivity factors (self-control strategies and parental restrictions) that may explain heterogeneity in social media-related distraction.

Social media, parenting, and well-being.

One of the key challenges faced by many parents is to manage the pervasiveness of social media in adolescents' lives and its effects on adolescents' well-being (e.g., life satisfaction) and ill-being (e.

Experience sampling self-reports of social media use have comparable predictive validity to digital trace measures.

Research agrees that self-reported measures of time spent with social media (TSM) show poor convergent validity, because they correlate modestly with equivalent objective digital trace measures. This experience sampling study among 159 adolescents (12,617 self-reports) extends this work by examining the comparative predictive validity of self-reported and digital trace measures of TSM, that is, the extent to which self-reported and digital trace measures of TSM correspond in their effects on self-esteem, well-being, and friendship closeness. Using an N = 1 method of analysis, we investigated the correspondence on a between-person, within-person, and person-specific level.

Some socially poor but also some socially rich adolescents feel closer to their friends after using social media.

Who benefits most from using social media is an important societal question that is centered around two opposing hypotheses: the rich-get-richer versus the poor-get-richer hypothesis. This study investigated the assumption that both hypotheses may be true, but only for some socially rich and some socially poor adolescents and across different time intervals. We employed a state-of-the-art measurement burst design, consisting of a three-week experience sampling study and seven biweekly follow-up surveys.

Social media use and its impact on adolescent mental health: An umbrella review of the evidence.

Literature reviews on how social media use affects adolescent mental health have accumulated at an unprecedented rate of late. Yet, a higher-level integration of the evidence is still lacking. We fill this gap with an up-to-date umbrella review, a review of reviews published between 2019 and mid-2021.

Social media use and friendship closeness in adolescents' daily lives: An experience sampling study.

The formation and maintenance of friendship closeness is an important developmental task in adolescence. To obtain insight in real-time processes that may underly the development of friendship closeness in middle adolescence, this preregistered experience sampling study [ESM] investigated the effects of social media use on friendship closeness. The study was conducted among 387 adolescents (54% girls; M = 14.

The effect of social media on well-being differs from adolescent to adolescent.

The question whether social media use benefits or undermines adolescents' well-being is an important societal concern. Previous empirical studies have mostly established across-the-board effects among (sub)populations of adolescents. As a result, it is still an open question whether the effects are unique for each individual adolescent.

Screen media use and ADHD-related behaviors: Four decades of research.

The diagnosis of attention-deficit/hyperactivity disorder (ADHD) among children and adolescents has increased considerably over the past decades. Scholars and health professionals alike have expressed concern about the role of screen media in the rise in ADHD diagnosis. However, the extent to which screen media use and ADHD are linked remains a point of debate.

Electronic Media Use and Sleep Among Preschoolers: Evidence for Time-Shifted and Less Consolidated Sleep.

This study examined the association between electronic media use and sleep among preschoolers, using a national sample of 402 mothers of 3- to 5-year-olds. Participants completed an online survey assessing preschoolers' electronic media use, bedtime and wake time, sleep time, napping behaviors, and sleep consolidation. Results showed that heavier television use and tablet use, both overall and in the evening, were associated with later bedtimes and later wake times, but not with fewer hours of sleep, providing evidence for a time-shifting process.

The role of sleep in the relation between young children's mobile media use and effortful control.

We explored the relations among young children's mobile media use, sleep, and a form of self-regulation, temperamental effortful control (EC), among a national sample of 402 mothers who completed an online survey. We found that the relation between mobile media use and EC was moderated by children's sleep time. Tablet use was negatively related to EC only among children who slept less at night (40% of our sample).

The Dual Role of Media Internalization in Adolescent Sexual Behavior.

Sexualizing media content is prevalent in various media types. Sexualizing media messages and portrayals emphasize unattainable body and appearance ideals as the primary components of sexual desirability. The internalization of these ideals is positively related to self-objectification and sexual body consciousness.

The Relation Between Use of Mobile Electronic Devices and Bedtime Resistance, Sleep Duration, and Daytime Sleepiness Among Preschoolers.

This study investigated the relation between preschoolers' mobile electronic device (MED) use and sleep disturbances. A national sample of 402 predominantly college-educated and Caucasian mothers of 3-5-year-olds completed a survey assessing their preschoolers' MED use, bedtime resistance, sleep duration, and daytime sleepiness. Heavier evening and daily tablet use (and to some extent, smartphone use) were related to sleep disturbances.

Online communication predicts Belgian adolescents' initiation of romantic and sexual activity.

Unlabelled: Online communication is associated with offline romantic and sexual activity among college students. Yet, it is unknown whether online communication is associated with the initiation of romantic and sexual activity among adolescents. This two-wave panel study investigated whether chatting, visiting dating websites, and visiting erotic contact websites predicted adolescents' initiation of romantic and sexual activity.
