Various studies conducted during the COVID-19 pandemic have confirmed changes in online behaviour, with young people increasingly using social networks. This trend appears to correlate with a heightened risk of various psychological and emotional problems. The main aim of this study is to explore the patterns of social network use among high school students amidst the pandemic, particularly focusing on the presence of specific emotional problems and potential gender differences. In addition, this study aims to contribute to the existing body of knowledge on the influence of lockdown measures on adolescents. A probabilistic sample of N = 825 students from 20 high schools in Zagreb participated in this study. Alongside basic sociodemographic variables, this study assessed social network habits and emotional problems using the Depression Anxiety Stress Scales 21 (DASS-21). The findings indicate intensive social media engagement during the pandemic. The results of the MANOVA analysis (gender x daily time on social media) show significant effects of both the time spent on social networks and gender on mental health, while no interaction effect was observed. Female students and those who spend more time on social media have higher levels of depression, anxiety, and stress symptoms. These findings underscore the need for addressing emotional problems and habits in the virtual environment of high school students and implementing appropriate preventive and treatment interventions.
