OBJECTIVES: To describe age and gender specific time trends in adolescent violence across 19 countries over 28 years. METHODS: The paper presents analysis of eight cycles of the Health Behaviour in School-aged Children (HBSC) Study from 1994-2022, involving 789,531 children aged 11, 13, and 15. Indicators of violence included physical fighting, school bullying and cyberbullying (from 2018). Log-binomial regression models were used to test for linear temporal trends, with Generalized Estimating Equations used to account for clustering by country. RESULTS: School bullying perpetration and victimization declined over time in each age/gender group in most countries. Similar declines were reported for frequent physical fighting among boys (all ages) and girls (age 15 only). The prevalence of violent behaviour was almost universally higher in boys in the early cycles than in girls, but this gender difference attenuated over time. For cyberbullying, significant increases were observed since 2018 in all groups except age 15 girls in most countries. CONCLUSION: This analysis of a large cross-national dataset suggests a decline in traditional forms of adolescent violence. However, the increases in cyberbullying warrant further monitoring.

OBJECTIVES: Problematic computer use is the use of computer technology that may be health-endangering and may cause immediate or later negative physical or psychological health outcomes or disturb well-being in users. The main purpose of this study was to review current empirical research on coping strategies which adolescents apply in the context of problematic computer use and the coping-relevant impacts of problematic computer use. METHODS: An integrative review of empirical studies using the Web of Science, Google Scholar, reference lists and forward tracking was conducted. Of the 404 articles identified, 28 peer-reviewed, full-text articles that directly addressed coping in relation to problematic Internet use, computer overuse and cyberbullying were included in the review. RESULTS: This review identified the structure of specific coping strategies related to problematic computer use as well as the general patterns of relationships between reviewed instances of problematic computer use, situational coping and dispositional coping. CONCLUSIONS: Instrumental action and talking with others were the most frequent strategies used by adolescents to cope with cyberbullying. The structure of the coping strategies related to problematic Internet use and computer overuse is highly differentiated, revealing a new and promising area for future research.
