Beyond the birds and the bees
Studies have shown positive outcomes for pleasure-based and LGBTQI+ inclusive sexuality education, yet to date, most sex education remains risk-based and cis-heteronormative. Teachers’ knowledge, attitudes and skills relevant to pleasure-based and LGBTQI+ inclusive sexuality education likely impact the provision and effectiveness of sexuality education. In this study, we examined (a) teachers’ knowledge, attitudes and (self-perceived) skills; (b)…
Using the Diffusion of Innovation Theory to explain the declining trend in adolescent drunkenness between 2002 and 2022 across 46 countries
INTRODUCTION: Using Diffusion of Innovations Theory, we investigated whether countries with higher innovation capacity showed earlier tipping points (shift from increasing to decreasing drunkenness) and steeper declines in adolescent drunkenness (2002-2022). Innovation capacity likely facilitates these shifts through knowledge generation, policy implementation, and norm diffusion. METHODS: Trends in adolescent drunkenness were examined across 46 …
Educational Differences in Sexual Health among Adolescents in Europe
In European countries with stratified educational trajectories, in which adolescents are separated into vocational and academic tracks, studies have shown that there are educational differences in adolescent sexual health. However, due to heterogeneity of the existing literature in terms of national educational systems and dimensions of sexual health being studied, uncertainty remains about the strength of the association between educational trac…
Mental Health Disparities Between Both-, Other- and Same-Sex Attracted Adolescents
Gender Sexuality Alliances and School Safety
While Gender and Sexuality Alliances (GSAs) are associated with higher acceptance of sexual diversity and lower bullying-victimization, it is unclear which individual and school-level attributes strengthen these associations. Nationally representative data ( N = 1,567 students; M age = 15.4, SD = 0.16; 34% boys, 66% girls, 51% heterosexual, 49% sexually-diverse after propensity score matching) in 139 Dutch secondary schools were used. Multilevel …
Trends and the Gender Gap in the Reporting of Sexual Initiation Among 15-Year-Olds
Early sexual intercourse initiation has been associated with immediate and long-term risks, which makes the study of trends in sexual initiation an important topic for policy makers. This study investigated trends over time in reported sexual initiation among 15-year-olds across 33 countries between 2010-2018. In addition, we examined if there were cross-country differences in the gender gap in reported sexual initiation in 2018, and whether thes…
Social and Economic Indicators of Psychological Symptoms and Life Satisfaction Among Dutch and Hong Kong Adolescents
Adolescent mental health and life satisfaction are grounded in social and economic factors. However, studies investigating these relations across European and Asian contexts, using identical questionnaires, are scarce. The 2017/18 Health Behaviour of School-aged Children (HBSC) study conducted with 4,168 Dutch adolescents ( Mage 13.0 years) and 1,948 Hong Kong adolescents ( Mage 13.1 years) aged 11, 13, and 15 reported on family status and afflue…
A Latent Profile Analysis of Social Support, Online Contacts, and Preference for Online Communication Among Same- and Both-Sex Attracted and Other-Sex Attracted Adolescents
This study aimed to assess differences between other-sex attracted and same- and both-sex attracted adolescents in profiles of peer and family social support, online contacts, and preferences for online communication. Data stem from the 2017 Dutch "Health and Behavior in School-Aged Children" (HBSC) survey (N = 6,823; 4.0% same- and both-sex attracted; M age=14.73, SD = 1.59, range = 12-18). We conducted latent profile analyses to estimate profil…
Abstainers and Drinkers – Two Sides of the Same Coin
This commentary discusses a recently published literature review focussing on the growing trend of young people abstaining from drinking alcohol. Despite the recent increase in research on the decline in youth drinking, the review only identified 10 papers that explicitly examined abstainers. The inclusion criteria used thus excluded and overlooked the vast literature available on the decline in youth drinking. This commentary discusses the impli…
The international Family Affluence Scale (FAS)
In the absence of suitable indicators of adolescent socioeconomic status, the Family Affluence Scale (FAS) was first developed in Scotland 25 years ago. Since then, it has been adapted for use in the Health Behaviour in School-Aged Children (HBSC) Study to research inequalities in adolescent health in Europe and North America. FAS has also been used as an indicator of adolescent socioeconomic status in research studies outside of HBSC, worldwide.…
The great decline in adolescent risk behaviours
In many high-income countries, the proportion of adolescents who smoke, drink, or engage in other risk behaviours has declined markedly over the past 25 years. We illustrate this behavioural shift by collating and presenting previously published data (1990-2019) on smoking, alcohol use, cannabis use, early sexual initiation and juvenile crime in Australia, England, the Netherlands, New Zealand, and the USA, also providing European averages where …
Structural gender inequality and gender differences in adolescent substance use
Societal gender inequality relates to gender differences in adolescent substance use.-The gender gap in adolescent substance use is larger in countries with higher levels of gender inequality.-Girls in these countries were less likely to get drunk, use alcohol or smoke cigarettes than boys
The association between MPOWER tobacco control policies and adolescent smoking across 36 countries
A decade after the introduction of the WHO MPOWER package, we observed that, in our sample of European countries and Canada, measures targeting social norms around smoking (i.e., smoke-free policies in public places and policies related to warning people about the dangers of tobacco) are most strongly related to declines in adolescent smoking
Social media use intensity, social media use problems, and mental health among adolescents
Social media have become increasingly integrated into the daily lives of adolescents. There are concerns about the potential detrimental effects of adolescents' social media use (SMU) on their mental health. Using a three-wave longitudinal study among 2109 secondary school adolescents (Mage = 13.1, SDage = 0.8), the present study examined whether high SMU intensity and addiction-like SMU problems were bidirectionally associated with low mental he…
Cross-National Time Trends in Adolescent Mental Well-Being From 2002 to 2018 and the Explanatory Role of Schoolwork Pressure
PURPOSE: 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: = 1.63) across five H…
Trends over Time in Adolescent Emotional Wellbeing in the Netherlands, 2005-2017
In some Scandinavian countries, the United Kingdom and the United States, there is evidence of a dramatic decline in adolescent emotional wellbeing, particularly among girls. It is not clear to what extent this decline can be generalised to other high-income countries. This study examines trends over time (2005-2009-2013-2017) in adolescent wellbeing in the Netherlands, a country where young people have consistently reported one of the highest le…
Do country-level environmental factors explain cross-national variation in adolescent physical activity? A multilevel study in 29 European countries
The findings showed that national differences in the physical, socio-cultural and economic environment were related to adolescent physical activity. They point to potential avenues for future research looking at interactions between individual and environmental factors
Country‐Level Gender Equality and Adolescents’ Contraceptive Use in Europe, Canada and Israel
More research is needed to identify potential causal pathways and mechanisms through which gender equality and adolescents' contraceptive use may influence one another
The Happiest Kids on Earth. Gender Equality and Adolescent Life Satisfaction in Europe and North America
Cross-national differences in adolescent life satisfaction in Europe and North America are consistent, but remain poorly understood. While previous studies have predominantly focused on the explanatory role of economic factors, such as national wealth and income equality, they revealed weak associations, at most. This study examines whether societal gender equality can explain the observed cross-national variability in adolescent life satisfactio…
Trends in adolescent alcohol use in the Netherlands, 1992–2015
This study shows clear time trend changes in alcohol use among Dutch adolescents. The phenomenal decrease in adolescent alcohol use since 2003 appears to be closely related to a radical change in parenting behaviours surrounding the alcohol use of their children. While national prevention programs may have encouraged stricter parenting behaviours, the decline in alcohol use should be interpreted in a broader context of internationally changing so…
Decreases in adolescent weekly alcohol use in Europe and North America
BACKGROUND: This study examined trends in adolescent weekly alcohol use between 2002 and 2010 in 28 European and North American countries. METHODS: Analyses were based on data from 11-, 13- and 15-year-old adolescents who participated in the Health Behaviour in School-Aged Children (HBSC) study in 2002, 2006 and 2010. RESULTS: Weekly alcohol use declined in 20 of 28 countries and in all geographic regions, from 12.1 to 6.1% in Anglo-Saxon countri…
Trends in alcohol-specific parenting practices and adolescent alcohol use between 2007 and 2011 in the Netherlands
Parent–Adolescent Sexual Communication and Its Association With Adolescent Sexual Behaviors
Sexual communication is a principal means of transmitting sexual values, beliefs, expectations, and knowledge from parents to children. Although this area has received considerable research attention, more studies with representative samples are needed to assure that findings are reflective of populations of interest. A nationally representative sample of parent-adolescent dyads (N = 2,965; mean adolescent age = 13.8 years) in the Netherlands was…
Explaining Educational Differences in Adolescent Substance Use and Sexual Activity
Secondary school adolescents attending vocational tracks engage considerably more often in substance use and sexual activity compared to those attending academic tracks. Prior studies have sought explanations for these differences in higher levels of social-emotional problems among vocational students. This study presents a novel approach. Inspired by ethnographic and cultural studies, it examines the role of conceptions and expectations of adult…
Early Risk Behaviors and Adolescent Injury in 25 European and North American Countries
Injury is a leading cause of mortality and morbidity among adolescents in developed countries. Jessor and Jessor’s Problem Behavior Theory suggests an association between risk behaviors (e.g., smoking, drunkenness, cannabis use, and sexual intercourse) and adolescent injury. The present study examined whether early engagement in risk behaviors would predict injury at age 15. It also examined whether such associations were consistent in strength a…
