Defender or Outsider? Understanding Individual, Social, and Contextual Factors in Cyberbystander Behavior in Cyberaggression
Bystanders’ responses play an important role in cyberaggression incidents among youth. This study examines factors differentiating cyberbystander roles as defenders or outsiders. Individual factors (gender, age, self-efficacy, and digital skills), social factors (parent, teacher, and peer mediation), contextual factors (victim’s age relative to the bystander, perceived victim’s emotional (upset) response, and bystander-victim relationship quality…
Analytical Robustness and Competing Interpretations in Violent Video Game Research
Recent debates on violent video game (VVG) effects highlight the importance of analytical robustness and transparency in longitudinal research. Teng and Bushman reanalyzed our prior study, identifying several methodological concerns and arguing that our conclusions were unwarranted. In this response, we examine their reanalysis and assess whether their conclusions hold across alternative analytical specifications and operational decisions. Throug…
Longitudinal associations between cyberbullying and cyberhate
Cyberbullying and cyberhate are two forms of cyberaggression that share several characteristics but differ in key aspects such as repetition, power imbalance, and the nature of their targets. Although often examined separately, their potential overlaps and the psychological mechanisms that distinguish them require further investigation. In this context, online empathy and moral disengagement may offer insight into the shared and distinct emotiona…
Empowerment or Pressure? Exploring the Impact of Female Body Depictions in Body Positivity Instagram Posts on Self‐Objectification
Although Body Positivity content (BoPo) has been criticised for emphasising physical appearance and promoting self-objectification, the specific features driving these effects remain unclear. The present study examined whether depictions of female bodies act as triggers for self-objectification in BoPo on Instagram. In a between-subjects online experiment involving 158 women aged 18-29 (M = 21.6, SD = 2.4), exposure to female bodies in BoPo posts…
Gaming together, feeling better—or feeling worse? How social video gaming impacts loneliness and depressive mood differently for boys and girls
Adolescents’ intentional and unintentional cyberhate exposure in Estonia, Finland, Germany, Italy, Poland, and Portugal
Cyberhate refers to hateful and biased online content that targets people based on their group membership. This study differentiates between intentional and unintentional cyberhate exposure and examines the role of perceived discrimination, with five dimensions of digital literacy as mediators. Data were collected via a three-wave longitudinal survey conducted over the span of three years (2021–2023) with 2,660 adolescents (aged 14–17 in W3) from…
Bias-Based Cyberaggression Related To Origin, Religion, Sexual Orientation, Gender, and Weight
Bias-based cyberaggression—hateful and bias-based content and interactions via information and communication technologies—is a frequent experience for young internet users that can result in detrimental consequences for both individuals and society. Ample research has focused on the factors related to involvement in bias-based cyberaggression. This study systematically reviews the research published in the past decade about the investigations int…
Navigating Beauty Standards on Social Media
Social media activity focused on physical appearance can heighten body dissatisfaction in adolescents. However, the mechanisms behind this association remain insufficiently examined. This three-wave longitudinal study analyzed data from 2500 Czech adolescents (aged 11–16, M = 13.4, SD = 1.7, 50% girls) to examine whether the comparison with social media appearance ideals and the internalization of these ideals mediate the association between appe…
Does violence in video games impact aggression and empathy? A longitudinal study of Czech adolescents to differentiate within- and between-person effects
The associations between exposure to violent video games (VVG) and aggression/empathy have been extensively studied. VVG are often depicted as triggers for increased aggression and decreased empathy in line with the General Aggression Model. However, longitudinal evidence that distinguishes within- and between-person effects and focuses on various dimensions of aggression/empathy remains scarce. Drawing on representative sample of 3010 Czech adol…
Adolescents' perceptions of the credibility of informational content on fitness and dietary supplements
INTRODUCTION: The assessment of online health-related information presents a significant challenge for today's youth. Using the Processing of Commercial Media Content (PCMC) model, we investigated the impact of advertising on the perceived credibility of informational content concerning fitness (in boys) and dietary supplements (in girls). METHODS: In a survey-based preregistered experiment, 681 Czech adolescents (aged 13-18, 52% girls) were rand…
Does aggressive commentary by streamers during violent video game affect state aggression in adolescents
In the past 10 years, live-streaming services have gained huge popularity. Streamers usually play video games and complement their performance with commentary. We examine the role of this streamer commentary on state aggression in Czech adolescents who were randomly assigned into one of the three experimental groups (i.e. aggressive commentary, non-aggressive commentary, no commentary). The findings suggest that a short-term streamer’s commentary…
The relation between the cyberhate and cyberbullying experiences of adolescents in the Czech Republic, Poland, and Slovakia
This study investigates the structural relationship between two types of cyberaggression: cyberhate and cyberbullying. Cyberhate is online hate speech that attacks collective identities. Cyberbullying is defined by the intent to harm, its repeated nature, and a power imbalance. Considering these features and the shared commonalities, we used survey data from adolescents from the Czech Republic, Poland, and Slovakia (N = 3,855, aged 11–17) to exam…
Coping with Public and Private Face-to-Face and Cyber Victimization among Adolescents in Six Countries
This study investigated the role of medium (face-to-face, cyber) and publicity (public, private) in adolescents' perceptions of severity and coping strategies (i.e., avoidant, ignoring, helplessness, social support seeking, retaliation) for victimization, while accounting for gender and cultural values. There were 3432 adolescents (ages 11-15, 49% girls) in this study; they were from China, Cyprus, the Czech Republic, India, Japan, and the United…
The Amplification of Cyberhate Victimisation by Discrimination and Low Life Satisfaction
There is some indication that discrimination as well as low levels of life satisfaction render young people at risk of cyberhate victimization. Adopting a socio-ecological perspective, this paper examines whether supportive family, peer and school environments may buffer against the effects of perceived discrimination and low life satisfaction on cyberhate victimization. Data from four countries ( N = 3396) of the EU Kids Online IV survey on chil…
Who Is Exposed to Harmful Online Content? The Role of Risk and Protective Factors Among Czech, Finnish, and Spanish Adolescents
The Direct and Indirect Effects of Online Social Support, Neuroticism, and Web Content Internalization on the Drive for Thinness among Women Visiting Health-Oriented Websites
One of the debates about media usage is the potential harmful effect that it has on body image and related eating disturbances because of its representations of the "ideal body". This study focuses on the drive for thinness among the visitors of various health-oriented websites and online platforms because neither has yet been sufficiently studied in this context. Specifically, this study aims to bring more insight to the risk factors which can i…
Markers of Sexual Life and Health in Association with Internet Use for Sexual Purposes in Czechs Aged 50 and Older
Cyberostracism
This study focuses on the effect of cyberostracism on social networking sites. Based on the temporal need-threat model of ostracism, we examined a) reflexive reactions, specifically worsened mood and threats to the four fundamental needs (i.e., belongingness, self-esteem, meaningful existence, and control), and b) reflective reactions, in the form of prosocial, antisocial, and avoidance behavior. We also focused on the role of social anxiety. Usi…
Factors influencing interactions between adolescents and unknown people from the internet
A considerable amount of adolescents’ interpersonal communication takes place online. Adolescents use the internet to interact with friends and family, but also with people who were previously unknown to them. This study focuses on two types of interactions with unknown people from the internet: online communication and offline face-to-face meetings. We used theoretical frameworks of adolescent developmental tasks and risk-taking behavior to iden…
Do Stereotypes of Mental and Developmental Disorders Predict Bystander Intentions in Cyberbullying? An Application of the Stereotype Content Model
It was investigated whether different types of mental or developmental disorders (MDD) would be rated differently in terms of stereotypic perceptions and behavioral tendencies and whether these effects of stereotypes on behaviors would be mediated vi
Role of school climate and personality in the development of Czech adolescents’ political self-efficacy
This study examined the effects of school climate (open classroom and positive student relationships) and personality dispositions (shyness and need for cognition) on adolescents’ political self-efficacy. Data were collected in 2014 from 1,954 Czech ninth- and tenth-graders (mean age = 15.60). A multilevel analysis showed that school-level political self-efficacy predicted self-efficacy for local politics. However, schools and classrooms were rat…

Nowadays, the prevailing trend in the science-society relationship is to engage with the broader public, which is beneficial for the public, scientific institutes, scientific findings, and the legitimacy of science as a whole. This article provides a broad review of the rapidly growing research on Open Science and identifies the gaps in the current knowledge for future research. The review focuses on the science-society relationship, such that kn…
Face-to-face and Cyber Victimization among Adolescents in Six Countries
Does ‘clicking’ matter? The role of online participation in adolescents’ civic development
This study focuses on the role of online civic participation in the civic development of adolescents. We build on the assumption that online civic participation differs from more traditional offline civic participation in several key characteristics, namely lacking proximity to other actors, possible disconnection between civic actions and their outcomes, and a reduced hierarchy within the online environment. Considering these specifics, the stud…
Differences in Severity and Emotions for Public and Private Face-to-Face and Cyber Victimization Across Six Countries
The purpose of this study was to examine the role of medium (face-to-face, cyber) and publicity (public, private) in perceptions of severity and emotional responses to victimization among adolescents from China, Cyprus, the Czech Republic, India, Japan, and the United States, while controlling for gender, individualism, and collectivism. There were 3,432 adolescents (age range = 11-15 years, 49% girls) included in this study. They read four hypot…
Bystanders' Support of Cyberbullied Schoolmates
This study examined factors that increase or decrease the support a bystander offered to a victim of cyberbullying. Possible determinants of supportive behaviour were analyzed using a four‐step hierarchical regression analysis on data from 156 Czech children (12–18 years old; M = 15.1; 54% females) who witnessed their schoolmates being victims of cyberbullying. Among individual characteristics, only a general tendency toward prosocial behaviour w…

Extent Matters
Adolescents use media that exposes them to sexual material. This study focused on adolescents in the Czech Republic, a country with relatively high rates of exposure to sexual material (ESM). A sample of adolescents aged 11 to 15 years ( N = 495) taken from the project EU Kids Online II was examined for predictors of the following: frequency of ESM, place of ESM, and, for online ESM, the types of sites. The only predictors of sporadic ESM were ag…
Predicting Online and Offline Civic Participation among Young Czech Roma
Roma in the Czech Republic represent a large ethnic minority that faces intolerance and social exclusion. This study aims to describe factors that boost civic participation among Roma adolescents and emerging adults. Specifically, it asks whether different factors apply to Roma and members of the majority, and whether different factors boost offline and online participation. Survey data were analysed from Roma (n = 157) and majority (n = 573) par…

Empathic responses by cyberbystanders
Cyberaggression, and its' specific sub-type, cyberbullying, have become a widely debated and studied issues, but we still lack knowledge about cyberbystanders, whose reactions (or lack thereof) can play a crucial role. One of the important factors determining behavioral outcomes is cyberbystanders’ empathic response to the incident. Certain features of cyberaggression incidents (e.g. distance and the invisibility of those involved) raise the ques…
Cyberbullying in context
Random samples of at least 1,000 youth, ages 9 to 16 years, from 25 European countries (N = 25,142) were used to test the salience of low self-control on cyberbullying perpetration and victimization (direct and indirect effects), framed by a cross-cultural developmental approach. Path models, which provided evidence of invariance by sex, tested the hypothesized links among low self-control as well as known correlates, including offline perpetrati…

Effectiveness of coping strategies for victims of cyberbullying
Although cyberbullying is a well-studied online risk, little is known about the effectiveness of various coping strategies for its victims. Therefore, this study on 2,092 Czech children aged 12-18 examined which coping strategies were applied most often and to what extent victims of cyber aggression judged them to be effective. Effectiveness was measured in two ways: the extent to which the coping strategy buffered negative emotions, and the exte…

Online only
This study examined whether people who prefer online over offline civic participation differ from those who participate in both environments, who prefer offline participation, or do not participate. Using a cross-sectional sample of young adults (age 18-28) recruited in the Czech Republic (N = 720), we compared these four groups (defined by their types of civic participation) regarding their socio-demographic profiles, trust (social, individual, …

Differences in Coping Strategies for Public and Private Face-to-Face and Cyber Victimization among Adolescents in Six Countries
The aim of this study was to examine the role of publicity (private versus public) and medium (face-to-face versus cyber) in adolescents’ coping strategies for hypothetical victimization, while also considering culture. Participants were adolescents from China, Cyprus, the Czech Republic, India, Japan, and the United States. The study also controlled for adolescents’ gender, individualism, and collectivism. Adolescents completed questionnaires on…
Whom to Trust
This study focuses on two coping strategies in cyberbullying: talking to parents and talking to peers. The subsample of cyberbullying victims aged 9–16 ( N = 1395; 59% female) from the EU Kids Online II project was analysed. We predicted talking to parents and peers according to mediation style, perceived harm, support‐seeking tendencies, parental knowledge of the child's activities online, age and gender. The results show that perceived harm and…
