To extend the scholarly debate on (a) whether or not compulsive use of games and social media should be regarded as behavioral addictions (Kardefelt-Winther et al., 2017) (b) nine DSM-5 criteria for Internet gaming disorder (IGD; American Psychiatric Association [APA], 2013) are appropriate to distinguish highly engaged, non-disordered users from disordered users, this study investigated impact engaged psychosocial well-being school performances adolescents.As part Digital Youth Project...

At the time of writing, about 4.59 billion people use social media with many adolescents using their accounts across a myriad applications and platforms. According to recent statistics, in 2022 individuals spent an average 151 minutes on each day, illustrating global relevance (Dixon, 2022a,b). One pressing questions, internationally, is whether harmful and/or addictive. This question particular importance because teenagers - younger spend considerable these platforms, which have...

ABSTRACT Aims To evaluate the effectiveness of two preventive interventions to reduce heavy drinking in first‐ and second‐year high school students. Design setting Cluster randomized controlled trial using four conditions for comparing active with a control group from 152 classes 19 schools Netherlands. Participants A total 3490 first‐year students (mean 12.68 years, SD = 0.51) their parents. Intervention (i) Parent intervention (modelled on Swedish Örebro Prevention Program) aimed at...

The popularity of social media use among adolescents has raised concerns about the potentially harmful effects on adolescents' sleep. Since longitudinal research considering this relationship is scarce, present two-wave study 2021 secondary school students (Mage = 13.86, SD 1.25) examined whether frequency and problematic predicted bedtime quality Moreover, protective role parental rules regarding Internet smartphone one hour before sleep was examined. findings indicated that strict might...

This study aimed to enhance knowledge on which aspects of the family context are most relevant in identifying at-risk/problematic social media users among adolescents. Therefore, we examined relative contribution adolescents' use (SMU) general and Internet-specific factors related three different (sub)systems: parent-child (Internet-specific rule-setting, reactive restrictions towards Internet use, co-use, involvement rule-setting positive parenting), parent (parental screen time, phubbing,...

To examine the effects of a parent and student intervention offered separately simultaneously (PAS) on onset weekly drinking via its putative mediators.A randomized trial with four conditions; (1) intervention, (2) (3) combined parent-student (4) control group.High schools selected randomly, located in different areas.A total 2937 early adolescents (mean age = 12.6, standard deviation 0.49) their parents.Mediation were analysed using pretest data two follow-up measurements (10 22 months...

This two-wave prospective study investigated the bidirectional relation between Internet-specific parenting (reactive restrictions, rules, and frequency quality of communication about Internet) adolescents' symptoms social media disorder (SMD) Internet gaming (IGD). In addition, we whether this was different for boys girls.A sample 352 adolescents (48.9% boys, Mage = 13.9, SDage 0.74, range: 11-15) completed questionnaires at two waves. Zero-inflated cross-lagged analyses in Mplus were...

Nowadays, parents, caretakers, teachers and researchers have an increasing interest in the development consequences of problematic social media use, especially among adolescents. A growing body research investigates factors that may influence use. This study examined role broader context parental (time spent with parents family support), peer (peer support pressure), individual (perceived self-control) adolescents' risky use (ref = normative), as well moderating self-control by using a...

Previous studies on general parenting have demonstrated the relevance of strict within a supportive social context for variety adolescent behaviors, such as alcohol use. Yet, alcohol-specific practices are generally examined separate predictors adolescents' drinking behavior. The present study different developmental profiles (rule-setting, quality and frequency communication about use) how these patterns relate to initiation growth drinking. A longitudinal sample 883 adolescents (47 %...

Abstract The use of smartphone-based location data to quantify behavior longitudinally and passively is rapidly gaining traction in neuropsychiatric research. However, a standardized validated preprocessing framework for deriving behavioral phenotypes from currently lacking. Here, we present consisting methods that are the context geospatial data. This aims generate context-enriched by identifying stationary, non-stationary, recurrent stationary states movement patterns. Subsequently, this...

Large-scale validation research on instruments measuring problematic social media use (SMU) is scarce. Using a nationally representative sample of 6,626 Dutch adolescents aged 12 to 16 years, the present study examined psychometric properties nine-item Social Media Disorder scale. The structural validity was solid, because one underlying factor identified, with adequate loadings. internal consistency good, but test information most reliable at moderate high scores scale’s continuum....

We investigate a method to estimate the combined effect of multiple continuous/ordinal mediators on binary outcome: (a) fit structural equation model with probit link for outcome and identity/probit mediators, (b) predict potential probabilities, (c) compute natural direct indirect effects. Step 2 involves rescaling latent continuous variable underlying address residual mediator variance covariance. evaluate estimation risk-difference- risk-ratio-based effects (RDs, RRs) using maximum...

Problematic social media use (PSMU) is a societal problem, which impacts adolescents' well-being. Fear of missing out (FoMO) has been suggested as core risk factor predicting both PSMU and However, longitudinal research on the directionality these relationships scarce. The present study aims to fill this knowledge gap by testing bidirectional between FoMO, adolescents’ life satisfaction in total sample, well for girls boys separately. This used four-waves annual data collected from 2015 2019...

To examine the reliability of self-reports on prevalence, frequency and quantity drinking in early adolescents by comparing questionnaires with diary reports. Retrospective data were obtained a questionnaire after conducting 1-month daily alcohol use sample 78 adolescents. Sensitivity, specificity, positive, negative predictive values correlations calculated to test whether reports corresponded Adolescents reported higher prevalence than The sensitivity predicted value low, whereas...

The personality trait sensory processing sensitivity (SPS) is an established risk factor for the development of internalizing problems. Highly sensitive adolescents react stronger to environmental cues including parenting environment and stressful life events. aim current study was examine if perceived impact COVID-19, mediates link between SPS In addition, it tested style moderates mediating effect COVID-19 problems among adolescents. had a cross- sectional design data were collected...

Although both Internet-specific and general parenting have been linked to adolescents' problematic social media use, until now they investigated as separate predictors of this behavior. As specific practices occur in the broader context, study examined how different (Internet-specific rule setting, reactive restrictions towards Internet co-use) dimensions (responsiveness autonomy-granting) co-occur, act together predicting use. Four-wave data 400 adolescents (T1: M age = 13.51 years, SD...

Objective: There is convincing evidence that parental rules about alcohol are important in curbing adolescents' use. However, little known the mechanisms through which direct link between alcohol-specific parenting and use obtained. In this study, we investigated mediating effect of adolescent self-control on relationship drinking behavior whether mediation depends level quality communication. Method: A total 883 adolescents participated longitudinal study at ages 13, 14, 15 years. Results:...

In this experimental study, it was examined to what extent peers and sex were important predictors of risk taking behavior adolescents. Participants 140 Dutch adolescents (52.9% boys, 12-15 years) who completed the Balloon Analogue Risk Task (BART) as a measure behavior, either individually or in presence homogenous heterogeneous peer groups. Results showed that (a) took significantly more when they BART with than task individually, (b) boys girls but not (c) “boy-only triads” revealed...
