The current experience sampling method (ESM) study examined whether adolescents who use more social media than their peers experience more distraction (between-person association), whether social media use (SMU) and distraction co-fluctuate within adolescents (momentary within-person associations), and to what extent this within-person association differs from person to person (person-specific associations). With a sample of 383 adolescents (Mage = 14.11), who together completed 35,099 ESM surveys (73% compliance), we found both a positive between-person association (ß = .31) and a positive momentary within-person association (ß = .12) of SMU with distraction. The momentary within-person association differed from adolescent to adolescent: While SMU and distraction were positively associated among 82.5% of all adolescents, they were not associated among 15.7% of the adolescents, and negatively associated among 1.8% of the adolescents. Additional analyses on the direction of the effect showed that the within-person effect of SMU on subsequent levels of distraction was somewhat stronger (ß = .05) than the effect of distraction on subsequent levels of SMU (ß = .03). 24 p.

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; Mage = 14.11 years; 96% Dutch) from different educational tracks (44% lower prevocational secondary education, 31% intermediate general secondary education, 26% academic preparatory education). Adolescents reported six times per day for 3 weeks on their Instagram, WhatsApp, and Snapchat use in the previous hour and their momentary experiences of friendship closeness (126 assessments; 34,930 observations). Multilevel analyses revealed positive between-person associations of friendship closeness with general WhatsApp use and Instagram use with close friends. In contrast, at the within-person level, we found small negative overall associations of general WhatsApp use and Instagram use (with and without close friends) with friendship closeness. However, there was large heterogeneity in the person-specific effect sizes of the within-person associations of social media use with friendship closeness. For example, person-specific effect sizes of the association of Instagram use with close friends with friendship closeness ranged from ß = -.745 to ß = .697. These results underline the importance of acknowledging person-specific effects in developmental and media effect theories. 15 p.

This longitudinal study investigated transactional relationships between violent media use and attention-deficit/hyperactivity disorder (ADHD)–related behaviors among young children (ages 4-8 years). To investigate study hypotheses, we employed a random intercept cross-lagged panel model (RI-CLPM) using structural equation modeling with panel data from 890 children. Results provided evidence in support of a media selection process rather than media effects process, whereby an increase in a child’s ADHD-related behaviors predicted an increase in the child’s violent media use 1 year later. Results indicated that this longitudinal relationship was accounted for by within-child fluctuations over time rather than stable between-child differences. The findings highlight the importance of investigating transactional relationships as well as distinguishing between-person and within-person relationships.

Item does not contain fulltext This study investigated the effects of active private, passive private, and passive public social media use on adolescents’ affective well-being. Intensive longitudinal data (34,930 assessments in total) were collected through a preregistered three-week experience sampling method study among 387 adolescents. N = 1 time series were investigated, using Dynamic Structural Equation Modeling. Findings showed that different types of social media use very rarely yielded different effects within one and the same adolescent: 45% of adolescents experienced no changes in well-being due to any of the three types of social media use, 28% only experienced declines in well-being, and 26% only experienced increases in well-being. Only one adolescent experienced the theoretically expected effect pattern of a positive effect of active private and passive private use and negative effect of passive public use. Together, the findings suggest that the active-passive use dichotomy in social media research is less clear-cut than it might seem. 13 december 2021 26 p.

Contains fulltext : 239443.pdf (Publisher’s version ) (Open Access) A recurring hypothesis in the literature is that "passive" social media use (browsing) leads to negative effects on well-being. This preregistered study investigated a rival hypothesis, which states that the effects of browsing on well-being depend on person-specific susceptibilities to envy, inspiration, and enjoyment. We conducted a three-week experience sampling study among 353 adolescents (13-15 years, 126 assessments per adolescent). Using an advanced N = 1 method of analysis, we found sizeable heterogeneity in the associations of browsing with envy, inspiration, and enjoyment (e.g., for envy ranging from β = -.44 to ß = +.71). The Passive Social Media Use Hypothesis was confirmed for 20% of adolescents and rejected for 80%. More adolescents with browsing-induced envy experienced negative effects on affective well-being (25%) than adolescents with no browsing-induced envy (13%). Conversely, more adolescents with browsing-induced enjoyment experienced positive effects on affective well-being (47%) than adolescents with no browsing-induced enjoyment (9%). Lay summary: 'A recurrent question among academics is whether social media browsing negatively affects teens' well-being. Some scholars believe that this browsing can lead to envy and declines in well-being. Others think that it can also lead to inspiration and enjoyment, and to increases in well-being. To investigate which scholars are right, we asked 353 teens to report six times a day for a period of three weeks how often they had browsed Instagram and Snapchat in the past hour. Furthermore, we asked them how much envy, inspiration, and enjoyment they had experienced in that hour, and how well they felt at that moment. We found sizeable differences among teens in the effects of browsing on well-being at that moment. While one group of teens (20%) felt worse after browsing, another group (17%) felt better. More teens who had felt envy while browsing, experienced negative effects on well-being than teens who did not feel such envy while browsing. Conversely, more teens who had felt enjoyment while browsing, experienced positive effects on well-being than teens who had not felt such enjoyment. 19 p.

Despite the crucial role of humor in t(w)eens’ media entertainment, we lack a theoretically informed approach to investigate the prevalence and co-occurrence of humor types in such entertainment. Therefore, this study tested a coding framework of humor in t(w)eens’ media entertainment by content-analyzing 107 television series (5,633 scenes) listed by 10- to 14-year-olds as their favorite. Results confirmed ten humor types (aggressive, slapstick, self-defeating, sexual, irreverent, coping, parody, wordplay, incongruity, absurdity) with aggressive humor most often and coping humor least often present (in 87.9% versus 23.4% of series, respectively). Humor types also frequently co-occurred, highlighting the need to revise existing theories.

Whether studies should rely on parent or child reports of parental mediation remains a much-debated question. We investigated the agreement between parent and adolescent reports of the frequency and style (autonomy-supportive, controlling, inconsistent) of restrictive and active mediation, and their relative validity. Results revealed perceptual differences, with parents reporting more autonomy-supportive mediation. With some exceptions, both parent and adolescent reports correlated with relevant criterion measures. Results suggest that parent and adolescent reports are equally valid to assess the frequency and style of mediation, and that both reports should be considered to obtain a complete understanding of parents’ mediation efforts.

We conducted a 3-week experience sampling (ESM) study among 300 adolescents (13-16 years; 126 assessments per adolescent; 21,970 assessments in total). Using an N = 1 method of analysis (Dynamic Structural Equation Modeling [DSEM]), we found that the within-person effects of time spent with SM on selfesteem ranged from strongly negative (ß = -.31) to moderately positive (β = +.27) across adolescents. Across all ESM observations of the valence of adolescents' SM experiences, 55% of these experiences were positive, 18% negative, and 27% neutral. Finally, 78% of adolescents experienced a positive within-person effect of the valence of SM experiences on self-esteem (β ≥ +.05), 19% no to a very small effect (-.05 < ß < +.05), and 3% a negative effect (ß

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. Our search yielded 25 reviews: seven meta-analyses, nine systematic, and nine narrative reviews. Results showed that most reviews interpreted the associations between social media use and mental health as ‘weak’ or ‘inconsistent,’ whereas a few qualified the same associations as ‘substantial’ and ‘deleterious.’ We summarize the gaps identified in the reviews, provide an explanation for their diverging interpretations, and suggest several avenues for future research.

A recurring claim in the literature is that active social media use (ASMU) leads to increases in well-being, whereas passive social media use (PSMU) leads to decreases in well-being. The aim of this review was to investigate the validity of this claim by comparing the operationalizations and results of studies into the association of ASMU and PSMU with well-being (e.g. happiness) and ill-being (e.g. depressive symptoms). We found 40 survey-based studies, which utilized a hodgepodge of 36 operationalizations of ASMU and PSMU and which yielded 172 associations of ASMU and/or PSMU with well-/ill-being. Most studies did not support the hypothesized associations of ASMU and PSMU with well-/ill-being. Time spent on ASMU and PSMU may be too coarse to lead to meaningful associations with well-/ill-being. Therefore, future studies should take characteristics of the content of social media (e.g. the valence), its senders (e.g. pre-existing mood), and receivers (e.g. differential susceptibility) into account.

Contains fulltext : 239197.pdf (Publisher’s version ) (Open Access) 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. Person-specific analyses of more than 70,000 observations from 383 adolescents revealed that 12% of the socially rich adolescents (high in friendship support or low in loneliness) felt closer to their friends after using social media, as opposed to about 25% of the socially poor adolescents (low in friendship support or high in loneliness). However, only 1 to 6% of all adolescents (socially rich and poor) felt closer both in the short- and longer-term. These results indicate that the rich-get-richer and the poor-get-richer hypotheses can hold both, but for different adolescents. 15 p.

Social competence refers to the ability to engage in meaningful interactions with others. It is a crucial skill potentially malleable to interventions. Nevertheless, it remains difficult to select which children, which periods in a child's life, and which underlying skills form optimal targets for interventions. Development of social competence is complex to characterize because (a) it is by nature context- dependent; (b) it is subserved by multiple relevant processes that develop at different times in a child's life; and (c) over the years multiple, possibly conflicting, ways have been coined to index a child's social competence. The current paper elaborates upon a theoretical model of social competence developed by Rose-Krasnor (Rose- Krasnor, 1997; Rose-Krasnor and Denham, 2009), and it makes concrete how underlying skills and the variety of contexts of social interaction are both relevant dimensions of social competence that might change over development. It then illustrates how the cohorts and work packages in the Consortium on Individual Development each provide empirical contributions necessary for testing this model on the development of social competence.

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. We sampled adolescents’ experiences six times per day for one week to quantify differences in their susceptibility to the effects of social media on their momentary affective well-being. Rigorous analyses of 2,155 real-time assessments showed that the association between social media use and affective well-being differs strongly across adolescents: While 44% did not feel better or worse after passive social media use, 46% felt better, and 10% felt worse. Our results imply that person-specific effects can no longer be ignored in research, as well as in prevention and intervention programs.

Many post-lingually deafened cochlear implant (CI) users report that they no longer enjoy listening to music, which could possibly contribute to a perceived reduction in quality of life. One aspect of music perception, vocal timbre perception, may be difficult for CI users because they may not be able to use the same timbral cues available to normal hearing listeners. Vocal tract resonance frequencies have been shown to provide perceptual cues to voice categories such as baritone, tenor, mezzo-soprano, and soprano, while changes in glottal source spectral slope are believed to be related to perception of vocal quality dimensions such as fluty vs. brassy. As a first step toward understanding vocal timbre perception in CI users, we employed an 8-channel noise-band vocoder to test how vocoding can alter the timbral perception of female synthetic sung vowels across pitches. Non-vocoded and vocoded stimuli were synthesized with vibrato using 3 excitation source spectral slopes and 3 vocal tract transfer functions (mezzo-soprano, intermediate, soprano) at the pitches C4, B4, and F5. Six multi-dimensional scaling experiments were conducted: C4 not vocoded, C4 vocoded, B4 not vocoded, B4 vocoded, F5 not vocoded, and F5 vocoded. At the pitch C4, for both non-vocoded and vocoded conditions, dimension 1 grouped stimuli according to voice category and was most strongly predicted by spectral centroid from 0 to 2 kHz. While dimension 2 grouped stimuli according to excitation source spectral slope, it was organized slightly differently and predicted by different acoustic parameters in the non-vocoded and vocoded conditions. For pitches B4 and F5 spectral centroid from 0 to 2 kHz most strongly predicted dimension 1. However, while dimension 1 separated all 3 voice categories in the vocoded condition, dimension 1 only separated the soprano stimuli from the intermediate and mezzo-soprano stimuli in the non-vocoded condition. While it is unclear how these results predict timbre perception in CI listeners, in general, these results suggest that perhaps some aspects of vocal timbre may remain.

Despite a large body of literature on the opportunities of parental mediation to enhance positive and offset negative media effects, a long-term view as to the development of such mediation across childhood is lacking. The current study aimed to address this gap by presenting a developmental approach to parental mediation. Using an accelerated longitudinal design with four-wave panel data of 729 children, we investigated developmental trajectories of restrictive and active mediation across early (3–6 years) and middle childhood (7–10 years) and potential individual differences in these trajectories. Results revealed that parents’ expressions of restrictive and active mediation follow a curvilinear pattern over time, whereby parents’ mediation efforts increase across early childhood, peak at around age 8, before slowly declining throughout middle childhood. In addition, the results indicated that parenting style and children’s social-emotional difficulties are important sources of individual differences in the trajectories, above and beyond demographics.

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. To understand the current state of the field and, ultimately, move the field forward, we provide a systematic review of the literature on the relationship between children and adolescents' screen media use and ADHD-related behaviors (i.e., attention problems, hyperactivity, and impulsivity). Using the Differential Susceptibility to Media effects Model as a theoretical lens, we systematically organize the existing literature, identify potential shortcomings in this literature, and provide directions for future research. The available evidence suggests a statistically small relationship between media and ADHD-related behaviors. Evidence also suggests that individual child differences, such as gender and trait aggression, may moderate this relationship. There is a clear need for future research that investigates causality, underlying mechanisms, and differential susceptibility to the effects of screen media use on ADHD-related behaviors. It is only through a richer empirical body that we will be able to fully understand the media-ADHD relationship. ispartof: PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA vol:115 issue:40 pages:9875-9881 ispartof: location:United States status: published

The increase in media multitasking among adolescents has raised concerns regarding its possible negative impact on sleep. Although cross-sectional studies have found a relationship between media multitasking and sleep problems, knowledge about the causal direction is lacking. In a first step to understand causality, we examined the longitudinal relationship between media multitasking and sleep problems among 1443 adolescents (7th and 8th graders, 11–15 years, 51% boys), who completed a questionnaire three times at three-to-four month intervals. We employed random intercept cross-lagged panel models, which specifically examine cross-lagged correlations within (rather than between) individuals. The findings showed no cross-lagged correlations for the overall sample. However, the results indicated that, for 7th graders and girls, media multitasking was (marginally) related to more subsequent sleep problems. Our findings provide first evidence that media multitasking may affect the sleep of 7th graders and girls.

The aim of this article is to improve understanding of self-effects in social media, and to compare self-effects with reception effects. Self-effects are the effects of messages the cognitions, emotions, attitudes, and behaviors of the message creators/senders themselves. A total of 4 theories have tried to explain self-effects in offline environments: self-persuasion, self-concept change, expressive writing, and political deliberation. The article reviews research into online self-effects that evolved from each of these theories, and argues why self-effects may be stronger online than offline. Based on this review, a model is introduced that helps explain how online self- and reception effects may coalesce and amplify each other. The article ends by presenting some suggestions for future research.

The main aim of this study was to examine the norms of expressing emotions on social media. Specifically, the perceived appropriateness (i.e. injunctive norms) of expressing six discrete emotions (i.e. sadness, anger, disappointment, worry, joy, and pride) was investigated across four different social media platforms. Drawing on data collected in March 2016 among 1201 young Dutch users (15–25 years), we found that positive expressions were generally perceived as more appropriate than negative expressions across all platforms. In line with the objective of the study, some platform differences were found. The expression of negative emotions was rated as most appropriate for WhatsApp, followed by Facebook, Twitter, and Instagram. For positive emotion expression, perceived appropriateness was highest for WhatsApp, followed by Instagram, Facebook, and Twitter. Additionally, some gender differences were found, while age showed little variations. Overall, the results contribute to a more informed understanding of emotion expression online.

Adolescents commonly use media and communication devices during academic activities, also referred to as academic-media multitasking. Although there is evidence for the short-term effect of academic-media multitasking on academic achievement, support for its long-term effect is lacking. Therefore, we investigated the long-term relationship between academic-media multitasking and academic achievement, and the possible underlying mechanism of academic attention problems using a three-wave longitudinal study, with time intervals of 3–4 months, among 1215 adolescents (11–15 years, 52% boys). Although academic-media multitasking and academic achievement were cross-sectionally related, the findings showed neither support for a direct nor indirect long-term relationship between academic-media multitasking and subsequent academic achievement scores. However, academic-media multitasking was associated with an increase in subsequent academic attention problems. This study indicates that concerns regarding the long-term impact of academic-media multitasking on academic achievement need to be qualified.

Recently, concerns have been raised that adolescents' prolific social media use may cause them to become less empathic. However, direct empirical evidence is missing and research suggests that social media use can also be beneficial for adolescents' psychosocial development. The present study aims to investigate whether and how social media use influences empathy. We surveyed 942 Dutch adolescents (10-14 years) twice, with a one-year interval. The results showed that social media use is related to an increase in cognitive and affective empathy over time. Specifically, adolescents' social media use improved both their ability to understand (cognitive empathy) and share the feelings of their peers (affective empathy). Social media use is related to an increase in empathy over a 1-year period.This effect holds for both the affective and the cognitive component of empathy.Sympathy is not related to social media use.

Touchscreen applications (apps) for young children have seen increasingly high rates of growth with more than a hundred thousand now available apps. As with other media, parents play a key role in young children's app selection and use. However, to date, we know very little about how parents select apps for their children. Guided by uses and gratification theory, a survey was conducted with 600 Dutch parents who had at least one child between three and seven years old. Across two studies, we identified parents' most important needs that drive their selection of children's apps as well as the extent to which these needs differ by parenting style. Results indicate five overarching parental needs when it comes to children's apps, and confirm that these needs vary by parenting style. Findings offer important insight into how parents select apps for their children. Parents have five primary needs when it comes to apps for their children (3-7).These parental needs vary by parenting style.Parents place the greatest priority on apps that entertain and support autonomy.

Cognitive, emotional, and arousal responses to violent games play a central role in theoretical explanations of how violent media may affect aggression. However, existing research has focused on a relatively narrow range of responses to violent games in experimental settings. This limits our understanding of whether and how violent game-induced responses relate to aggression in real life. To address these gaps, this study investigated how cognitive effort, emotional valence, and arousal in response to violent games relate to early adolescents' aggression, both cross-sectionally and over a period of one year. In addition, we investigated how a social context variable (i.e., family conflict) predicts these responses to violent games and subsequent aggression. A sample of 448 early adolescents (10-14 years) completed survey questions and media diaries that measured their responses to violent games. Results showed that, outside the lab, a positive cross-sectional relationship between violent game-induced arousal and aggression exists. In addition, arousal mediated the relationship between family conflict and aggression. Study findings justify increased research attention to media responses outside the lab and a need for further theoretical and methodological refinement. We examined youths' responses to violent games using surveys and media diaries.Cross-sectionally, self-reported arousal was positively related to aggression.Arousal mediated between family conflict and aggression.Cognitive effort was negatively related to aggression in cross-sectional analyses.No longitudinal relationships were found between game responses and aggression.

This review analyzes trends and commonalities among prominent theories of media effects. On the basis of exemplary meta-analyses of media effects and bibliometric studies of well-cited theories, we identify and discuss five features of media effects theories as well as their empirical support. Each of these features specifies the conditions under which media may produce effects on certain types of individuals. Our review ends with a discussion of media effects in newer media environments. This includes theories of computer-mediated communication, the development of which appears to share a similar pattern of reformulation from unidirectional, receiver-oriented views, to theories that recognize the transactional nature of communication. We conclude by outlining challenges and promising avenues for future research.

We integrate and interpret studies on media multitasking and youths' functioning.Media multitasking is negatively related to aspects of cognitive control.Media use during academic activities is negatively related to academic performance.Media multitasking is negatively related to emotional functioning and sleep.We present five main directions for future research. The increasing prevalence of media multitasking among youth has raised concerns regarding its negative effects on youths' functioning. Although the number of empirical studies on the consequences of media multitasking for youth has grown rapidly, there has been no attempt to integrate theory with the results of these studies. This review integrates available findings on the relationship between media multitasking and three domains of youths' functioning: cognitive control, academic performance, and socioemotional functioning. Three databases (PsycINFO, ERIC, and CMMC) were searched to identify relevant studies, resulting in 8448 citations. Fifty-six studies met the inclusion criteria: nine studies on cognitive control, 43 on academic performance, and four on socioemotional functioning. Overall, the findings indicate a small to moderate negative relationship between media multitasking and the three domains of youths' functioning. However, evidence regarding the causal direction of this relationship is lacking. Based on the included studies, we identify several research gaps and present five main directions for future research: examining causality, establishing more targeted theories, improving media multitasking measurements, focusing on individual and contextual differences, and including representative samples.

Online sexual self-presentation is highly influenced by peer norms.Girls who present themselves in sexual ways are evaluated more negatively by other girls but more positively by boys.Boys who present themselves in sexual ways are evaluated more positively by girls but not by boys. The aims of this study were to investigate (a) the role of peer factors in adolescents' sexual self-presentation on social network sites, and (b) how adolescents who present themselves sexually online are evaluated by others. 238 high school students (aged 12-18) evaluated either a sexual or non-sexual online presentation of same-sex and opposite-sex peers. Moreover, they filled in a questionnaire about their own self-presentation behavior. Findings showed that peer norms played a crucial role in whether adolescents posted sexual pictures of themselves online. Moreover, need for popularity was a strong predictor for posting such pictures. Girls who presented themselves in sexual ways were evaluated more negatively by other girls but more positively by boys. Similarly, boys who presented themselves in sexual ways were evaluated more positively by girls but not by boys.

Most youth and media researchers do not believe that media affect all youth in the same manner or to the same degree. While most media effects theories reflect this belief, empirical efforts often do not. Rather than conceptualizing individual differences as noise or nuisance variables, we argue that the future of media effects research lies within understanding these differences. To that end, the aim of this article is to help youth and media researchers identify appropriate moderators for study inclusion. We discuss the concept of differential susceptibility, with a particular focus on the differences between orchid and dandelion children, highlighting theoretical and empirical applications of this susceptibility paradigm to media effects research. We believe that a more integrative approach to youth and media research, built on a differential susceptibility paradigm in which moderators are thoughtfully integrated a priori, can provide us with nuanced answers to the complex questions associated with youth and media effects.

Research on how sexual music videos affect beliefs related to sexual aggression is rare and has not differentiated between the effects of music videos by male and female artists. Moreover, little is known about the affective processes that underlie the effects of sexual music videos. Using data from a nationally representative three-wave panel survey among 1,204 Dutch adolescents, structural equation modeling showed that viewing sexual music videos by male artists increased the acceptance of female token resistance (i.e., the notion that women say “no” to sex when they actually mean “yes”) among adolescent girls, but not adolescent boys. Furthermore, viewing sexual music videos by male artists influenced girls’ acceptance of token resistance indirectly via affective engagement. The findings suggest that effects of sexual music videos on stereotypical sexual beliefs depend on the specific type of music video and viewers’ gender, and can be partly explained by viewers’ affective engagement.

We investigate which adolescents receive negative peer feedback in social media.Risky online behavior increased the risk of receiving negative feedback.Risky behavior was predicted by higher age, sensation seeking, and family conflict.These characteristics lead to negative feedback through risky online behavior.So, adolescents' characteristics indirectly predicted receiving negative feedback. Receiving negative peer feedback in social media may have negative consequences for adolescents' psychosocial development and well-being. Therefore, the first aim of this study was to investigate online behavior (i.e., online social exploration, risky online self-presentation) that predicts receiving negative online peer feedback. The second aim was to examine three types of precursors that may predict this online behavior and, indirectly, negative feedback: (a) developmental (i.e., sex, age), (b) dispositional (i.e., sensation seeking, inhibitory control), and (c) social precursors (i.e., peer problems, family conflict). We collected survey data among 785 Dutch adolescents (10-15years old). Our results showed that adolescents who engaged in online social exploration and risky online self-presentation more often, were more likely to receive negative peer feedback. Online social exploration was more prevalent among the older adolescents and adolescents characterized by higher sensation seeking and more family conflict. In addition, risky online self-presentation was more prevalent among adolescents high in sensation seeking. Consequently, these adolescents' online behavior, indirectly, made them more at risk of receiving negative peer feedback in social media.

Recently, the American Psychiatric Association included Internet gaming disorder (IGD) in the appendix of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The main aim of the current study was to test the reliability and validity of 4 survey instruments to measure IGD on the basis of the 9 criteria from the DSM-5: a long (27-item) and short (9-item) polytomous scale and a long (27-item) and short (9-item) dichotomous scale. The psychometric properties of these scales were tested among a representative sample of 2,444 Dutch adolescents and adults, ages 13-40 years. Confirmatory factor analyses demonstrated that the structural validity (i.e., the dimensional structure) of all scales was satisfactory. Both types of assessment (polytomous and dichotomous) were also reliable (i.e., internally consistent) and showed good criterion-related validity, as indicated by positive correlations with time spent playing games, loneliness, and aggression and negative correlations with self-esteem, prosocial behavior, and life satisfaction. The dichotomous 9-item IGD scale showed solid psychometric properties and was the most practical scale for diagnostic purposes. Latent class analysis of this dichotomous scale indicated that 3 groups could be discerned: normal gamers, risky gamers, and disordered gamers. On the basis of the number of people in this last group, the prevalence of IGD among 13- through 40-year-olds in the Netherlands is approximately 4%. If the DSM-5 threshold for diagnosis (experiencing 5 or more criteria) is applied, the prevalence of disordered gamers is more than 5%.

The first aim of this study was to investigate the concurrent and longitudinal relationships between adolescents' use of social network sites (SNSs) and their social self-esteem. The second aim was to investigate whether the valence of the feedback that adolescents receive on SNSs can explain these relationships. We conducted a three-wave panel study among 852 pre- and early adolescents (10–15 years old). In line with earlier research, we found significant concurrent correlations between adolescents' SNS use and their social self-esteem in all three data waves. The longitudinal results only partly confirmed these concurrent findings: Adolescents' initial SNS use did not significantly influence their social self-esteem in subsequent years. In contrast, their initial social self-esteem consistently influenced their SNS use in subsequent years. The valence of online feedback from close friends and acquaintances explained the concurrent relationship between SNS use and social self-esteem, but not the longitudinal relationship. Results are discussed in terms of their methodological and theoretical implications., Highlights • Social self-esteem (SSE) longitudinally predicts higher SNS use. • SNS use marginally predicts over-time improvements in SSE. • Feedback from friends and acquaintances explains the concurrent SNS-SSE relation. • Feedback from friends leads to over-time improvements in SSE. • Feedback from acquaintances does not result in over-time changes in SSE.

Epistemic curiosity (EC) is the desire to obtain new knowledge capable of either producing positive experiences of intellectual interest (I-type) or of reducing undesirable conditions of informational deprivation (D-type). Although researchers acknowledge that there are individual differences in young children’ se pistemic curiosity, there are no existing measures to assess the I- and D-type constructs of EC in early childhood. The aim of this study was to develop and validate parent-report scales that reliably assessed early expressionsof I-and D- typeECin young children. To develop the I/D-Young Children (I/D-YC) scales, 16 potential items were administeredto316parentsofchildrenaged3to8.Theseitemswere adaptations of an existing adult self-report measure of EC as well as newly developed items. Confirmatory factor analyses demonstrated that a 10-item 2-factor (5 I-type, 5 D-type) model had the best fit. Construct validity analyses and psychometric data indicated that our newly developed I/D-YC scales are valid and reliable measures of individual differences in early expressions of I- and D-type EC.

This study examined the relationship between media violence exposure and Attention-deficit/hyperactivity disorder (ADHD)-related behaviors. Using survey (parent-reported) and genetic data of 1,612 Dutch children (aged 5 to 9 years), we examined genetic disposition as a possible cause of individual differences in children's use of and susceptibility to media violence. The gene variant of interest was the 5-HTTLPR polymorphism, which has been associated with ADHD-related behaviors in previous research. Results showed that the "long" variant of the gene polymorphism was related to greater violent media use, which in turn was related to more ADHD-related behaviors. The 5-HTTLPR genotype did not moderate the effect of media violence on ADHD-related behaviors. This study provides insight into the role of genetic factors in media effects.

Males who watched more Internet pornography, were dissatisfied with their body.Males who watched more Internet pornography, were dissatisfied with their stomach size.Watching Internet pornography was unrelated to males' satisfaction with their penis size.Watching Internet pornography was unrelated to females' body satisfaction. Research on the consequences of exposure to sexually explicit Internet material (SEIM) has neglected body dissatisfaction as a potential outcome. Additionally, research on body dissatisfaction has ignored exposure to SEIM as a potential predictor. Within a social comparison framework, we studied whether exposure to SEIM predicted overall body dissatisfaction, as well as dissatisfaction with one's stomach size, penis size (for males), and breast size (for women). Based on a two-wave panel survey held among a nationally representative sample of 1879 Dutch respondents we found that more frequent exposure to SEIM increased males' dissatisfaction with their body in general and their stomach in particular. However, more frequent exposure to SEIM did not increase males' dissatisfaction with their penis size. Among females, SEIM was generally unrelated to body dissatisfaction. The effects of exposure to SEIM on the various dimensions of body dissatisfaction differed neither by age nor by sexual orientation.

However, this causal effect has not been investigated among children in middle childhood, who are in the midst of consumer development. Furthermore, the mechanism underlying this relation has not been studied. To fill these lacunae, this study focused on the longitudinal relation between children's television advertising exposure and materialism. We investigated advertised product desire as a mediating variable. A sample of 466 Dutch children (ages 8-11) was surveyed twice within a 12-month interval. The results show that advertising exposure had a positive longitudinal effect on materialism. This effect was fully mediated by children's increased desire for advertised products. 19 p.

This study investigated perceptions of love across the lifespan using Sternberg’s triangular theory of love, which distinguishes between passion, intimacy, and commitment. The study aimed to (a) investigate the psychometric properties of the short Triangular Love Scale (TLS-short) in adolescents and adults (see Appendix), and (b) track age and gender differences in the three love components of the TLS-short in a sample of 12- to 88-year-olds (N = 2791). The three-factor structure of the TLS-short was confirmed in both the adolescent and adult sample. Adolescents (12–17 years) reported lower levels of all love components compared to young adults (18–30 years). Late adults (50+) reported lower levels of passion and intimacy, but similar levels of commitment compared to young (18–30 years) and middle adults (30–50 years). Gender differences in the perceptions of all three love components were present but less sizeable than suggested in popular accounts and earlier academic research.

The aim of this study was to develop the Perceived Parental Media Mediation Scale (PPMMS). The PPMMS measures adolescents' perceptions about how frequently their parents restrict or actively discuss their media use, and in what style (i.e., autonomy-supportive, controlling, or inconsistent). In a first study among 761 preadolescents and early adolescents (10–14 years), we confirmed that the subscales of the PPMMS could be distinguished. In a second study, in which 499 adolescents were surveyed again, the test–retest reliability and validity of the PPMMS were established. The PPMMS met the standards of reliability, validity, and utility. Subscales correlated in the expected directions with general parenting styles, family conflict, prosocial behavior, and antisocial behavior.

In this theoretical article, we introduce the Differential Susceptibility to Media Effects Model (DSMM), a new, integrative model to improve our understanding of media effects. The DSMM organizes, integrates, and extends the insights developed in earlier microlevel media-effects theories. It distinguishes 3 types of susceptibility to media effects: dispositional, developmental, and social susceptibility. Using the analogy of a mixing console, the DSMM proposes 3 media response states that mediate media effects: cognitive, emotional, and excitative. The assumptions on which the DSMM is based together explain (a) why some individuals are more highly susceptible to media effects than others, (b) how and why media influence those individuals, and (c) how media effects can be enhanced or counteracted.

This study evaluated whether common self-report measures of television and game violence exposure represent reliable and valid measurement tools. Three self-report measures—direct estimates, user-rated favorites, and agency-rated favorites—were assessed in terms of test-retest reliability, criterion validity (their relationship with coded media diaries), and construct validity (their relationship with aggression and gender). A total of 238 adolescents participated in a two-wave survey and completed two media diaries. For game violence, the three self-report measures were reliable and valid. For television violence, only direct estimates achieved test-retest reliability and construct validity. Criterion validity could not be established for the television violence measures because the media diary was not a valid criterion for television violence. Our findings indicate that both direct estimates and favorites are valid measures for game violence, whereas for television violence, only direct estimates are valid. We conclude with a discussion about ways to further improve upon and reconceptualize media violence exposure measurement.

The first aim of this study was to investigate whether instant messaging (IM) influences adolescents’ ability to initiate offline friendships. The second aim was to study the validity of two underlying mechanisms that may account for this relationship: (a) the opportunities offered by IM to communicate with a variety of people, and (b) to disclose intimate information. A three-wave longitudinal study was conducted among 690 Dutch adolescents (10-17 years old). Results show that adolescents’ IM use increased their ability to initiate offline friendships over time. Furthermore, IM use indirectly increased adolescents’ ability to initiate offline friendships through the diversity of their online communication partners. These findings suggest that adolescents can practice social skills online and learn to relate to a variety of people, which, over time, may increase their ability to initiate offline friendships.

Contains fulltext : 103034.pdf (Publisher’s version ) (Closed access) This study develops and tests a model of children's critical processing of advertising. Within this model, 2 paths to reduced advertising susceptibility (i.e., attitude toward the advertised brand) were hypothesized: a cognitive path and an affective path. The secondary aim was to compare these paths for different thought verbalization processes: think-aloud and thought-listing. The model was tested on a sample of 8- to 12-year-old children (N = 163). Structural equation modeling revealed that, for children in the think-aloud group, both cognitive and affective paths were successful in reducing advertising susceptibility. However, for children in the thought-listing group, only the affective path was successful. These findings suggest that the think-aloud process increased children's motivation and ability to critically process advertising messages.

This study investigated whether unfamiliar characters are as effective as familiar characters in stimulating children's affective responses toward healthy foods. In particular, the authors investigated whether an unfamiliar character which is congruent with a product can be as effective as a familiar character. The authors tested 2 types of character-product congruence: conceptual congruence (on the basis of a familiar link), and perceptual congruence (on the basis of color similarity). In a repeated measures design, 166 children (4-6 years old) were exposed to a picture of a carrot combined randomly with 5 different types of character: an (incongruent) familiar character and four unfamiliar characters varying in character-product congruence (i.e., both conceptually and perceptually congruent, conceptual only, perceptual only, and incongruent). The authors measured children's automatic affective responses toward these character-product combinations using a time-constrained task, and elaborate affective responses using a nonconstrained task. Results revealed that the conceptually congruent unfamiliar characters were just as effective as the familiar character in increasing children's automatic affective responses. However, the familiar character triggered the most positive elaborate affective responses. Results are explained in light of processing fluency and parasocial relationship theories.
