Overall, while still common in many countries, bullying victimization is decreasing. The differences between countries highlight the need to further investigate measures undertaken in countries demonstrating a downward trend.
Previous research has shown inconsistent time trends in adolescent mental well-being, but potential underlying mechanisms for such trends are yet to be examined. This study investigates cross-national time trends in adolescent mental well-being (psychosomatic health complaints and life satisfaction) in mainly European countries and the extent to which time trends in schoolwork pressure explain these trends. Methods: Data from 915,054 adolescents from 36 countries (50.8% girls; mean age ¼ 13.54; standard deviation age ¼ 1.63) across five Health Behaviour in School-aged Children surveys (2002, 2006, 2010, 2014, and 2018) were included in the analyses. Hierarchical multilevel models estimated cross-national trends in adolescent mental well-being and schoolwork pressure. We also tested whether schoolwork pressure could explain these trends in mental well-being. Results: A small linear increase over time in psychosomatic complaints and schoolwork pressure was found. No change in life satisfaction emerged. Furthermore, there was large cross-country variation in the prevalence of, and trends over time in, adolescent mental well-being and
IMPLICATIONS AND CONTRIBUTION
Cross‐national analyses explore the consistency of the relationship between negative school experiences and involvement in bullying across 40 European and North American countries, using the 2006 (40 countries n = 197,502) and 2002 (12 countries, n = 57,007) WHO–HBSC surveys. Measures include two Cumulative Negative School Perception (CNSP) scales, one based on 6 mandatory items (2006) and another including an additional 11 items (2002). Outcome measures included bullying perpetration, victimization and involvement as both bully and victim. Logistic regression analyses suggested that children with only 2–3 negative school perceptions, experience twice the relative odds of being involved in bullying as compared with children with no negative school perceptions. Odds Ratios (p < 0.001) increase in a graded fashion according to the CNSP, from about 2.2 to over 8.0. Similar consistent effects are found across gender and almost all countries. Further research should focus on the mechanisms and social context of these relationships.
ObjectiveThe epidemiology of violence against children is likely to differ substantially by sex and age of the victim and the perpetrator. Thus far, investment in effective prevention strategies has been hindered by lack of clarity in the burden of childhood violence across these dimensions. We produced the first age-specific and sex-specific prevalence estimates by perpetrator type for physical, sexual and emotional violence against children globally.DesignWe used random effects meta-regression to estimate prevalence. Estimates were adjusted for relevant quality covariates, variation in definitions of violence and weighted by region-specific, age-specific and sex-specific population data to ensure estimates reflect country population structures.Data sourcesSecondary data from 600 population or school-based representative datasets and 43 publications obtained via systematic literature review, representing 13 830 estimates from 171 countries.Eligibility criteria for selecting studiesEstimates for recent violence against children aged 0–19 were included.ResultsThe most common perpetrators of physical and emotional violence for both boys and girls across a range of ages are household members, with prevalence often surpassing 50%, followed by student peers. Children reported experiencing more emotional than physical violence from both household members and students. The most common perpetrators of sexual violence against girls aged 15–19 years are intimate partners; however, few data on other perpetrators of sexual violence against children are systematically collected internationally. Few age-specific and sex-specific data are available on violence perpetration by schoolteachers; however, existing data indicate high prevalence of physical violence from teachers towards students. Data from other authority figures, strangers, siblings and other adults are limited, as are data on neglect of children.ConclusionsWithout further investment in data generation on violence exposure from multiple perpetrators for boys and girls of all ages, progress towards Sustainable Development Goals 4, 5 and 16 may be slow. Despite data gaps, evidence shows violence from household members, peers in school and for girls, from intimate partners, should be prioritised for prevention.Trial registration numberPROSPERO 2015: CRD42015024315.
Between 2002 and 2010, adolescent physical fighting declined in most countries. Specific groups of adolescents require targeted violence reduction programs. Possible determinants responsible for the observed declines are discussed.
