Digital skills among youth: A dataset from a three-wave longitudinal survey in six European countries.

This dataset provides longitudinal survey data from a European project, ySKILLS, which was focused on the role of digital skills in youths' development. It contains data from 10,821 participants from Grades 6-10 (in Wave 1) in Estonia, Finland, Germany, Italy, Poland, and Portugal. The data was collected between Spring 2021 and Spring 2023, the participants were recruited through schools, where the data collection also took place, except for online data collections due to restrictions caused by COVID-19. The dataset is novel in its multidimensional approach to the construct of digital literacy. It provides insight into the development of digital skills in youth and the role of digital skills and internet usage in youths' positive and negative online experiences and wellbeing. It also contains data that allows for the analysis of the role of digital skills in class networks. The data are beneficial for researchers interested in the examination of youths' online skills, internet usage, online experiences, and wellbeing from a longitudinal perspective.

'I wish my body looked like theirs!': How positive appearance comments on social media impact adolescents' body dissatisfaction.

Despite robust research evidence for the role of attractive-body portrayals in body image, the effect of positive appearance comments that endorse them on social media remains unclear. Therefore, using a between-subject experimental design and the data from 613 Czech adolescents (52% girls) aged 13-18 (M = 15.5, SD = 1.7), the present study examined exposure to positive appearance comments on body dissatisfaction, and the moderating roles of media-ideal internalization, appearance schematicity, body appreciation, and gender. Our data supported the presumed intensifying effect of the positive appearance comments on post-exposure body dissatisfaction, but only for adolescent girls. The impact of positive comments was not moderated by the media-ideal internalization, appearance schematicity, or body appreciation. However, the exploratory results showed that the displayed bodies' perceived attractiveness intensified the positive comments' effect on body dissatisfaction, which makes it a potentially important factor to target for the prevention of negative social media effects on body image. Furthermore, the individual characteristics that moderated the exposure to attractive images in the prior research may not determine the effects of the positive comments. Future research may need to capture factors that specifically influence the processing of such comments, such as susceptibility to peer feedback on physical appearance.

The validity of the Czech version of Body Appreciation Scale-2 for adolescents.

BACKGROUND: Understanding the formation of body image is critical for the prevention and treatment of eating disorders, especially in adolescence, when body image develops significantly. One of the important facets of body image is body appreciation, which consists of positive feelings and attitudes towards the body regardless of its perceived "flaws". To measure body appreciation, Body Appreciation Scale-2 (Tylka and Wood-Barcalow in Body Image 12:53-67, 2015a), a unidimensional 10-item measure, has been developed and routinely used in body image research. The current study examined the validity (i.e., factor structure, gender and age invariance, associations with other constructs) of the Czech version of Body Appreciation Scale-2 for adolescents. METHODS: The study used two large samples of Czech adolescents, aged 13-18 (N1 = 613, M = 15.5, 52% girls; N2 = 1,530, M = 15.4, 50% girls). The data were collected in August 2021 (N1) and November 2020 (N2) through an online survey. For the data analysis, we used confirmatory factor analysis (CFA), multi-group confirmatory factor analysis (MG-CFA), and Structural Equation Modeling (SEM). RESULTS: Our findings supported the proposed unidimensional factor structure and the gender (i.e., girls, boys) and age (i.e., 13-15, 16-18) scalar invariance of the Czech version of Body Appreciation Scale-2. The data also showed the expected positive correlations with body satisfaction and self-esteem, and negative correlations with media-ideal internalization, appearance schematicity, and depression. Furthermore, we discovered that body appreciation was more strongly connected to media-ideal internalization and depression for girls than boys. CONCLUSIONS: The present study provided robust evidence that supports the validity of the Czech version of Body Appreciation Scale-2 and its usability for the assessment of body appreciation in Czech adolescents. We also proposed future directions for the research on body appreciation based on the explored gender differences.

Understanding the formation of body image­that is, how people view and evaluate their bodies­is crucial for the prevention and treatment of eating disorders. This is especially true in adolescence, when body image develops significantly. That being said, the psychological assessment of body image, both in research and practice, requires reliable, high-quality measurement scales. Since its development by Tylka and Wood-Barcalow (2015a), Body Appreciation Scale-2 has been routinely used to assess body appreciation, which includes positive attitudes towards one's body despite its perceived "flaws". Our study provides evidence for the quality of the Czech version of Body Appreciation Scale-2 for use with adolescents. We examined the scale's characteristics on data from two robust samples (613 and 1530 Czech adolescents). Our study showed that the qualities of Czech Body Appreciation Scale-2 are satisfactory, and we recommend the scale for the assessment of body appreciation for adolescents in the Czech context. We also documented that the scale scores can be accurately compared between adolescent girls and boys, and younger (13­15) and older (16­18) adolescents. Additionally, we discovered gender differences in the relationships between body appreciation and depressive moods and the internalization of media ideals, which demands further exploration in future research.

Bystanders' Victim Blaming and Minimizing Consequences of Weight-Based Cyberhate Attacks: The Roles of anti-Fat Attitudes, Body-Positive Online Content, and Gender.

Physical appearance and, specifically, weight are common reasons for cyberhate attacks among adolescents. Using a between-subject experimental design, this study focuses on the bystanders of such attacks on Instagram. We investigate bystanders' assessments in the form of two moral disengagement (MD) mechanisms-victim blaming and minimizing consequences-and we compare the assessments of attacks that are diversified by the victim's weight (i.e., a victim who is plus-size and a victim who is thinner). We also examine the moderating roles of bystanders' prejudice against people who are plus-size in the form of the so-called anti-fat attitudes, their frequency of viewing body-positive online content, and gender. The study's data come from an online survey conducted in 2020 with a representative sample of 658 Czech adolescents, aged 13-18. We tested our hypotheses with structural equation modeling. The results show that the two MD mechanisms work differently. The victim's displayed weight affected the bystanders' tendency to victim blame: adolescents blamed the victim who is plus-size more than the victim who is thinner, but the victim's weight made no difference in minimizing the consequences of the incident. A moderating effect for anti-fat attitudes and gender was found for victim blaming. Bystanders with higher anti-fat attitudes and boys blamed the victim who is plus-size more than the victim who is thinner. On the other hand, there was no effect for the frequency of viewing body-positive online content for either of the MD mechanisms. The results are discussed with regard to the differences between the two mechanisms and the practical implications for educational and prevention programs for youth.

Coping with Public and Private Face-to-Face and Cyber Victimization among Adolescents in Six Countries: Roles of Severity and Country.

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 States. Adolescents completed questionnaires on individualism and collectivism, and ratings of coping strategies and severity for public face-to-face victimization, private face-to-face victimization, public cyber victimization, and private cyber victimization. Findings revealed similarities in adolescents' coping strategies based on perceptions of severity, publicity, and medium for some coping strategies (i.e., social support seeking, retaliation) but differential associations for other coping strategies (i.e., avoidance, helplessness, ignoring). The results of this study are important for prevention and intervention efforts because they underscore the importance of teaching effective coping strategies to adolescents, and to consider how perceptions of severity, publicity, and medium might influence the implementation of these coping strategies.

A moderated mediation model for body-positive online content and body image among adolescents.

Body-positive online content (BPOC) has recently become widespread, yet the factors that explain its association with body satisfaction have scarcely been studied. The current study investigates the indirect association between the self-reported frequency of viewing BPOC and body satisfaction through body appreciation and the moderating roles of body-ideal internalization, self-esteem, intentional searching, and gender. Utilizing survey data from 1530 Czech adolescents aged 13-18 (M=15.4, SD=1.7, 50 % girls), the present study found limited support for an indirect connection between the frequency of viewing BPOC and body satisfaction through body appreciation. Nonetheless, an indirect association appeared among adolescents with average and above-average frequencies for intentional searching for BPOC. Other investigated moderating factors were not significant. The present findings suggest that BPOC may be positively associated with body image, but only for those who deliberately search for it. The study highlights the importance of individual moderating factors in the context of BPOC and the remaining research gaps, such as the examination of its various types and aspects and their relationship with body image.

Evaluation of Web-Based Health Information From the Perspective of Women With Eating Disorders: Thematic Analysis.

BACKGROUND: Users with experience of eating disorders use the internet as a source of information, whether for prorecovery activities (such as web-based treatment, looking for information, support, and sharing) or activities that promote eating disorder behavior as a desirable lifestyle choice (such as pro-eating disorder communities and reading and creating pro-eating disorder posts). Their assessment of web-based eating disorder-related information is crucial for understanding the context of the illness and for health professionals and their web-based interventions. OBJECTIVE: This study aimed to understand the criteria young women with the experience of eating disorders use in evaluating eating disorder-related web-based information and what eating disorder-related characteristics of these women are involved in their evaluation. METHODS: We analyzed 30 semistructured individual interviews with Czech women aged 16 to 28 years with past or present eating disorder experience using a qualitative approach. Thematic analysis was adopted as an analytical tool. RESULTS: The specifics of eating disorder phases (the disorder stage and the treatment process) emerged as important aspects in the process of information assessment. Other specific characteristics of respondents (eg, motivation, abilities, and resources) addressed how the respondents arrived at certain web-based information and how they evaluated it. In addition, the respondents described some content cues as features of information (eg, novelty and social information pooling). Another finding is that other users' attitudes, experiences, activities, and personal features are involved in the information evaluation of these users and the information presented by them. Finally, the respondents evaluated the websites' visual look and graphic components. CONCLUSIONS: This study shows that web-based information evaluation reported by women with experience of eating disorders is a complex process. The assessment is influenced by current personal characteristics related to the illness (mainly the motivation for maintaining or curing the eating disorder) using cues associated with information content, other users, and website look. The study findings have important implications for health professionals, who should ask their clients questions about web-based communities and their needs to understand what information and sources they choose.

Who Is Exposed to Harmful Online Content? The Role of Risk and Protective Factors Among Czech, Finnish, and Spanish Adolescents.

Although adolescents' exposure to harmful online content has been linked to decreased subjective well-being and offline risky behaviors, there is limited research on the factors that underlie such problematic online behavior. Using the conceptual framework of Problem Behavior Theory, this study examined the role of risk (i.e., emotional problems, sensation seeking) and protective (i.e., the quality of family environment, social support from friends) factors in exposure to harmful online content among 4473 12- to 16-year-olds (M = 13.9, SD = 1.3, 49% girls) in the Czech Republic, Finland, and Spain. Individual country samples included 1848 adolescents from the Czech Republic (age: M = 14, SD = 1.4; 51% girls), 788 from Finland (age: M = 13.9, SD = 1.3; 52% girls), and 1837 from Spain (age: M = 13.5, SD = 1.2; 47% girls). In all of the sampled countries, emotional problems and sensation seeking served as risk factors, whereas good family relationships were protective. In some countries, the effects of emotional problems and sensation seeking were moderated by the quality of the family environment and social support from friends. These moderating effects suggest that individual risk factors for exposure to harmful online content may be buffered by a positive family environment and friends' support. The findings revealed similarities in the risk and protective factors underlying online problem behavior across three different countries. They demonstrate that the mechanisms proposed by Problem Behavior Theory can help to understand the etiology of adolescent problem behavior across different countries as well as offline and online contexts.

The motivation for citizens' involvement in life sciences research is predicted by age and gender.

Open Science is an umbrella term encompassing multiple concepts as open access to publications, open data, open education and citizen science that aim to make science more open and transparent. Citizen science, an important facet of Open Science, actively involves non-scientists in the research process, and can potentially be beneficial for multiple actors, such as scientists, citizens, policymakers and society in general. However, the reasons that motivate different segments of the public to participate in research are still understudied. Therefore, based on data gathered from a survey conducted in Czechia, Germany, Italy, Spain, Sweden, and the UK (N = 5,870), this study explores five types of incentives that can motivate individuals to become involved in life sciences research. The results demonstrate that men and younger individuals are more persuaded by extrinsic motives (external benefits or rewards), as compared with women and older people, who are driven by intrinsic motives (that originates from within an individual). This paper shows that specific strata of the population are differentially motivated to engage in research, thereby providing relevant knowledge for effectively designing public involvement activities that target various groups of the public in research projects.

Bystander reactions to cyberbullying and cyberaggression: individual, contextual, and social factors.

This article reviews recent literature focused on the factors associated with the reactions of youth bystanders to cyberaggression. The studies examined factors from three topical areas. The first area concerns the role of individual factors, with specific focus on the role of moral disengagement. The second area concerns the contextual factors and the applicability of the bystander intervention model, the bystander effect in the online environment, and the severity of the incident. The third area comprises social factors, with focus on the effect of class and school, and the interactions between individual and social levels. Taking into the reviewed literature, recommendations are formulated regarding the measurement of cyberbystander reactions, the need to capture contextual factors, and the examination of social factors.

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 increase the drive for thinness in the users of these websites. We tested the presumption that web content internalization is a key factor in this process, and we considered the effects of selected individual factors, specifically the perceived online social support and neuroticism. We utilized survey data from 445 Czech women (aged 18-29, M = 23.5, SD = 3.1) who visited nutrition, weight loss, and exercise websites. The results showed a positive indirect link between both perceived online social support and neuroticism to the drive for thinness via web content internalization. The results are discussed with regard to the dual role of online support as both risk and protective factor. Moreover, we consider the practical implications for eating behavior and weight-related problems with regard to prevention and intervention.

Sociodemographic, Attitudinal, and Behavioral Correlates of Using Nutrition, Weight Loss, and Fitness Websites: An Online Survey.

BACKGROUND: Nutrition, diet, and fitness are among the most searched health topics by internet users. Besides that, health-related internet users are diverse in their motivations and individual characteristics. However, little is known about the individual characteristics associated with the usage of nutrition, weight loss, and fitness websites. OBJECTIVE: The aim of this study was to examine the individual factors associated with the usage of nutrition, weight loss, and fitness websites. METHODS: An invitation to an online survey was published on 65 websites and discussion forums. In total, we employed data from 623 participants (aged 13 to 39 years, mean 24.11 [SD 5.26]). The measures included frequency of usage of nutrition, weight loss and fitness websites, excessive exercise, eating disorder symptomatology, internalization of the beauty ideal, weight status, and perceived online social support. Participants' data were used as predictors in a base linear regression model. RESULTS: The final model had an acceptable fit (χ210 =14.1; P=.17; root mean square error of approximation=0.03; comparative fit index=0.99; Tucker-Lewis index=0.99). Positive associations were found between usage of (1) nutrition websites and being female, higher levels of excessive exercise, and perceived online social support; (2) weight loss websites and excessive exercise, internalization, being female, eating disorder symptomatology, and being overweight or obese; and (3) fitness websites and levels of excessive exercise, internalization, and frequency of internet use. CONCLUSIONS: The results highlighted the importance of individual differences in the usage of health-related websites.

Functions of mHealth applications: A user's perspective.

The usage of mobile health (mHealth) applications is rapidly increasing. This research has been aimed mostly at reviewing existing mHealth apps and their functionality. However, studies from users' perspectives are rather scarce. This exploratory study addresses that gap and, using cross-sectional survey data, seeks to reveal the socio-demographic and individual characteristics of users who utilize specific functions of mHealth apps. The data were collected via an online survey through websites oriented toward eating habits, exercising, dieting, and weight loss. From the original sample (1002 users; M = 24.8, standard deviation = 6.9; 81.6% females), the final sub-sample of 406 participants aged from 13 to 39 years (M = 23.8, standard deviation = 5.3, 86.9% females) who reported usage of mHealth apps was examined. The analyses revealed demographic and individual differences in predicting usage of various functions of mHealth apps. The drive for thinness was associated with functions for weight monitoring and planning functions. Excessive exercise was associated with weight monitoring, socializing functions, and functions for planning and monitoring goals. These findings imply that mHealth apps should be individually tailored to incorporate components such as risk-specific warnings or the provision of information related to seeking professional help for at-risk audiences.

Face-to-face and Cyber Victimization among Adolescents in Six Countries: The Interaction between Attributions and Coping Strategies.

The purpose of this study was to examine the impact of publicity (private, public) and medium (face-to-face, cyber) on the associations between attributions (i.e., self-blame, aggressor-blame) and coping strategies (i.e., social support, retaliation, ignoring, helplessness) for hypothetical victimization scenarios among 3,442 adolescents (age range 11-15 years; 49% girls) from China, Cyprus, the Czech Republic, India, Japan, and the United States. When Indian and Czech adolescents made more of the aggressor-blame attribution, they used retaliation more for public face-to-face victimization when compared to private face-to-face victimization and public and private cyber victimization. In addition, helplessness was used more for public face-to-face victimization when Chinese adolescents utilized more of the aggressor-blame attribution and the self-blame attribution. Similar patterns were found for Cypriot adolescents, the self-blame attribution, and ignoring. The results have implications for the development of prevention and intervention programs that take into account the various contexts of peer victimization.

Who crosses the norms? Predictors of the readiness for non-normative political participation among adolescents.

This study investigated whether adolescents' readiness for non-normative political participation (i.e., readiness to confront social rules for political reasons) was predicted by their interpersonal problems (with parents, teachers, and classmates), low optimism, and political beliefs (political self-efficacy and distrust in public institutions). A structural equation model using two-wave longitudinal data from Czech high school students (N = 768; 54% females; age range at T1 = 14-17, M = 15.97; T2 data collected 1.5 years later) showed that the changes in adolescents' readiness for non-normative participation were predicted by their lower institutional trust. Interpersonal relationships or optimism had no cross-sectional or longitudinal effect on the readiness for non-normative participation. These results suggest that the main source of adolescents' readiness for non-normative political actions lies in their political beliefs, while the effect of adolescents' interpersonal problems is less clear.

Who are mobile app users from healthy lifestyle websites? Analysis of patterns of app use and user characteristics.

The use of online communities and websites for health information has proliferated along with the use of mobile apps for managing health behaviors such as diet and exercise. The scarce evidence available to date suggests that users of these websites and apps differ in significant ways from non-users but most data come from US- and UK-based populations. In this study, we recruited users of nutrition, weight management, and fitness-oriented websites in the Czech Republic to better understand who uses mobile apps and who does not, including user sociodemographic and psychological profiles. Respondents aged 13-39 provided information on app use through an online survey (n = 669; M age = 24.06, SD = 5.23; 84% female). Among users interested in health topics, respondents using apps for managing nutrition, weight, and fitness (n = 403, 60%) were more often female, reported more frequent smartphone use, and more expert phone skills. In logistic regression models, controlling for sociodemographics, web, and phone activity, mHealth app use was predicted by levels of excessive exercise (OR 1.346, 95% CI 1.061-1.707, p < .01). Among app users, we found differences in types of apps used by gender, age, and weight status. Controlling for sociodemographics and web and phone use, drive for thinness predicted the frequency of use of apps for healthy eating (ß = 0.14, p < .05), keeping a diet (ß = 0.27, p < .001), and losing weight (ß = 0.33, p < .001), whereas excessive exercise predicted the use of apps for keeping a diet (ß = 0.18, p < .01), losing weight (ß = 0.12, p < .05), and managing sport/exercise (ß = 0.28, p < .001). Sensation seeking was negatively associated with the frequency of use of apps for maintaining weight (ß = - 0.13, p < .05). These data unveil the user characteristics of mHealth app users from nutrition, weight management, and fitness websites, helping inform subsequent design of mHealth apps and mobile intervention strategies.

Differences in Attributions for Public and Private Face-to-face and Cyber Victimization Among Adolescents in China, Cyprus, the Czech Republic, India, Japan, and the United States.

The authors' aim was to investigate gender and cultural differences in the attributions used to determine causality for hypothetical public and private face-to-face and cyber victimization scenarios among 3,432 adolescents (age range = 11-15 years; 49% girls) from China, Cyprus, the Czech Republic, India, Japan, and the United States, while accounting for their individualism and collectivism. Adolescents completed a questionnaire on cultural values and read four hypothetical victimization scenarios, including public face-to-face victimization, public cyber victimization, private face-to-face victimization, and private cyber victimization. After reading the scenarios, they rated different attributions (i.e., self-blame, aggressor-blame, joking, normative, conflict) according to how strongly they believed the attributions explained why victimization occurred. Overall, adolescents reported that they would utilize the attributions of self-blame, aggressor-blame, and normative more for public forms of victimization and face-to-face victimization than for private forms of victimization and cyber victimization. Differences were found according to gender and country of origin as well. Such findings underscore the importance of delineating between different forms of victimization when examining adolescents' attributions.

Individual Differences Associated with Exposure to "Ana-Mia" Websites: An Examination of Adolescents from 25 European Countries.

This study explores the individual differences associated with adolescents' exposure to "ana-mia" websites (i.e., websites where people discuss ways to be very thin, such as being anorexic). Participants were adolescents from a large cross-national survey in 25 European countries (N = 18,709, aged 11-16, 50% girls). Sociodemographic and individual factors (i.e., variables related to Internet use and personality traits) were included in a logistic regression performed separately for girls and boys. The results showed that sensation seeking and online disinhibition were both associated with an increased risk of exposure to "ana-mia" websites in girls as well as in boys, although some gender differences were apparent. In girls, but not in boys, the older the child and higher the socioeconomic status, higher the chance of being exposed to "ana-mia" websites. Further research is recommended to understand the real impact of "ana-mia" website exposure on adolescent health.

Bystanders' responses to offline bullying and cyberbullying: The role of empathy and normative beliefs about aggression.

Cyberbullying often takes place with the virtual presence or knowledge of bystanders. While we have some evidence about the determinants of bystanders' responses to offline bullying, we lack empirical studies concerning the variables that influence bystanders' responses to cyberbullying. The current study examines bystanders' responses to offline bullying and cyberbullying incidents. Two types of responses were captured: support toward the victims and the reinforcement of bullies' actions. Using data from 321 German adolescents (ages 12-18; M = 14.99; 44% girls), the association between bystanders' responses and normative beliefs about verbal aggression and cyberaggression, and affective and cognitive empathy, were tested in a path model. Both types of normative beliefs positively predicted the reinforcement of bullies, and normative belief about verbal aggression also predicted support for the victims of offline bullying. Both types of empathy predicted support in offline bullying, but only affective empathy predicted support in cyberbullying. There was no link between affective or cognitive empathy to the reinforcement of bullies. Moreover, bystanders' tendencies to respond supportively to the victim or to reinforce the bully were rather consistent in both cyber- and offline bullying, but there was no link between support and reinforcement. The findings are discussed with regard to implications for prevention and intervention efforts.

Brief report: The bystander effect in cyberbullying incidents.

This study examined the bystander effect in cyberbullying. Using self-reported data from 257 Czech respondents who had witnessed a cyberbullying attack, we tested whether provided help decreased with increased number of other bystanders. We controlled for several individual and contextual factors, including empathy, social self-efficacy, empathic response to victimization, and relationship to the victim. Results showed that participants tend to help the victims more in incidents with only one or two other bystanders. We also found that, as in the "offline" realm, bystander effect is not linear: no significant differences were found between incidents with a moderate number (3-10) and a larger number of total bystanders. Our findings, thus, provide support for the presence of the bystander effect in cyberbullying.
