Background: Everyday internet usage is particularly significant in the population of adolescents and young people. Besides numerous benefits, internet usage brings certain risks of addictive behavior. Internet Addiction Test (IAT) is the most spread scale for measuring internet addiction. The aim of this study was to investigate internet addiction on a sample of Croatian adolescents. Methods: Overall, 352 students aged between 15 and 20 from randomly selected high schools participated in the study. We have collected the data on the Internet Addiction Test along with basic demographic information. The main analyses included the factorization of IAT test and the measurement of prevalence of internet addiction with the analysis of the gender differences. Results: The results showed that 3.4% of high school students reported high levels of internet addiction, while 35.4% of respondents reported some signs of addiction. Three-factor structure of IAT was obtained with dimensions: Emotional and cognitive internet preoccupation, then Neglecting work and lack of self-control and the last one is Social problems. Although the first factor has the most significant role in internet addiction risk, gender differences were found only in the last two factors, where boys have higher scores on Social Problems, while girls have higher scores on Neglecting work and lack of self-control. Conclusions: Based on our results, the prevention activities should be focused on the area of ​​emotional and social competence and the responsible use of internet. Since the result show that a third of the sample show moderate signs of addiction, programs of both indicated and selective prevention should be systematically planned for the general population of adolescents as well as for the groups in risk. The obtained gender differences indicate that the preventive and treatment programs should take into account gender specifics.

The COVID-19 pandemic caused a transition to online services in almost all aspects of life. Today, online access is an important aspect of child well-being more than ever. The aim of the study was to investigate online activities and gender differences of children with a special focus on harmful online content, cyberbullying, and Internet addiction. Our research was conducted among students from one Croatian county (average age = 14.97, N = 494). The Internet Addiction Test, the European Cyberbullying Intervention Project Questionnaire, as well as questions constructed for the purposes of this research (e.g., online contents) were used. Between 20% and 30% of students spend four or more hours a day online. Furthermore, 14.57% of students showed moderate signs of addiction, and 1.42% already showed severe signs of addiction, where girls had significantly higher results. The results indicated that 12.75% of students were victims, 5.87% were perpetrators, and 8.3% were, at the same time, committing and experiencing cyberbullying. Children who commit and/or experience cyberbullying achieve higher results on the scale of Internet addiction than children who do not participate in cyberbullying. These findings contribute to our understanding of Internet usage and especially its problematic aspect in such a complex time as the COVID-19 pandemic, and they can be useful for planning future interventions with children.

Internet addiction and cyberbullying among youth are phenomena that show a significant increase owing to the development of technology and the wide accessibility of the Internet. Research was conducted among adolescents (N = 352) in 9...

The aim of this study was to investigate the opinion of authors on the overall quality and effectiveness of reviewers’ contributions to reviewed papers. We employed an on-line survey of thirteen journals which publish articles in the field of life, social or technological sciences. Responses received from 193 authors were analysed using a mixed-effects model in order to determine factors deemed the most important in the authors’ evaluation of the reviewers. Qualitative content analysis of the responses to open questions was performed as well. The mixed-effects model revealed that the authors’ assessment of the competence of referees strongly depended on the final editorial decision and that the speed of the review process was influential as well. In Ordinary Least Squares (OLS) analysis on seven questions detailing authors’ opinions, perception of review speed remained a significant predictor of the assessment. In addition, both the perceived competence and helpfulness of the reviewers significantly and positively affected the authors’ evaluation. New models were used to re-check the value of these two factors and it was confirmed that the assessment of the competence of reviewers strongly depended on the final editorial decision.

Online contacts and other activities on the Internet came into focus given the increased use during the COVID-19 pandemic. The online environment is a setting for problematic Internet use, including cyberbullying, and research so far shows that inclusion in cyberbullying depends on the amount of screen time. Increases in screen time during the pandemic could affect the growth of the prevalence rates of children’s involvement in cyberbullying. The aim of this paper is to compare the Internet habits, cyberbullying and parental role in children’s online activities before and during the COVID-19 pandemic, when the use of the Internet increased due to online classes and implemented measures to prevent the spread of the infection. The Institute of Public Health of Split-Dalmatia County conducted a quantitative online survey of Internet habits and problematic Internet use in two waves in 2017 and 2020 with adolescents from 12–18 (N₂₀₁₇ = 536; N₂₀₂₀ = 284). Research included adherence to ethical standards of research with children. An online activity questionnaire for children, a questionnaire of parental behaviors and the European Cyberbullying Intervention Project Questionnaire—ECIPQ were used. The results of the research point out that cyberbullying rates in the pandemic decreased. The results show that the cumulative effect of parental monitoring is medium with approximately 5% of explained variance for experiencing and 6% for committing violence. The similar set of predictors is statistically significant in both regressions. Parental actions of monitoring applications, informing children and monitoring search history are identified as protective factors for committing or experiencing cyber violence. These findings are important for understanding the effect of the general digitization of society, which leads to an extensive increase in the use of online content and various digital tools, and the role of the parents, especially as protective potential for cyberbullying among children.

Background. This study examines the behavioral responses of adolescents to online sexual harassment based on their roles as victims, perpetrators, both, or neutral participants. Methods. Data from a national sample of Croatian high school students (N = 2016) were used to investigate the influence of these roles on reaction patterns. This study explores coping strategies among students involved in online sexual harassment as victims, perpetrators, or both. Results. Students with dual roles rarely sought help from parents, teachers, or helplines, while perpetrators avoided confiding in friends or siblings. Conversely, uninvolved students were most likely to seek support from these sources. Victims often confided in friends and responded by blocking, confronting, deleting content, or avoiding the harasser. Dual-role students commonly mirrored the harassment they experienced, suggesting a cycle of retaliation and blurred victim–perpetrator boundaries. Interestingly, no significant role-based differences were found for passive responses like ignoring harassment or reporting on social media platforms. Conclusion. These results underline the critical need for targeted interventions to foster digital resilience and tailor support mechanisms based on adolescents’ experiences and roles in online interactions. This research contributes to the understanding of role-specific behavioral dynamics in the digital sphere, offering actionable insights for educators, policymakers, and mental health professionals to enhance online safety and support systems for youth.
