Cross-national time trends in adolescent body weight perception and the explanatory role of overweight/obesity prevalence
Introduction Body weight perception (BWP) is associated with health behaviors. Current evidence points to an increase over time in both actual and perceived weight status among adolescents, however there is limited evidence on time trends in BWP in cross-national samples of adolescents. Therefore, the aims of this study were to examine time trends in BWP between 2002 and 2018 among adolescents from 41 countries and regions, including gender and country differences and to explore the role of changes over time in country-level overweight/obesity prevalence in these trends. Methods Data were used from five cycles (2002, 2006, 2010, 2014, 2018) of the repeated cross-sectional Health Behavior in…
Cross-national validation of the social media disorder scale: findings from adolescents from 44 countries
Background and aims: There is currently no cross-national validation of a scale that measures problematic social media use (SMU). The present study investigated and compared the psychometric properties of the social media disorder (SMD) scale among young adolescents from different countries. Design: Validation study. Setting and participants: Data came from 222 532 adolescents from 44 countries participating in the health behaviour in school-aged children (HBSC) survey (2017/2018). The HBSC survey was conducted in the European region and Canada. Participants were on average aged 13.54 years (standard deviation = 1.63) and 51.24% were girls. Measurement: Problematic SMU was measured using th…
Item response theory and differential test functioning analysis of the HBSC-Symptom-Checklist across 46 countries
Abstract Background The Symptom Checklist (SCL) developed by the Health Behaviour in School-aged Children (HBSC) study is a non-clinical measure of psychosomatic complaints (e.g., headache and feeling low) that has been used in numerous studies. Several studies have investigated the psychometric characteristics of this scale; however, some psychometric properties remain unclear, among them especially a) dimensionality, b) adequacy of the Graded Response Model (GRM), and c) measurement invariance across countries. Methods Data from 229,906 adolescents aged 11, 13 and 15 from 46 countries that participated in the 2018 HBSC survey were analyzed. Adolescents were selected using representative s…

Trends in Adolescent Overweight Perception and Its Association With Psychosomatic Health 2002–2014 : Evidence From 33 Countries
Purpose Perceiving oneself as overweight is common and strongly associated with adolescents' subjective well-being. The prevalence of overweight perceptions and their impact on well-being may have increased over the past decade due to an increase in the salience of weight-related issues. This study examines trends (2002–2014) in the prevalence of adolescent overweight perceptions and their association with psychosomatic complaints. Methods Data from 15-year-old adolescents were obtained between 2002 and 2014 in four rounds of the Health Behaviour in School-aged Children study in 33 countries in Europe and North America (N = 187,511). Design-adjusted logistic regressions were used to quantif…
