School socioeconomic status and psychological complaints among adolescents in 44 countries: The mediating role of schoolwork pressure and classmate support and the moderating role of family SES and country-level income inequality.

Previous research has reported both positive and negative associations between school socioeconomic status (SES) and internalizing problems among adolescents. Little is known about cross-national differences in this association, as well as potential mediators and moderators. Therefore, this study investigated this association using representative cross-national samples of adolescents whilst exploring the mediating role of schoolwork pressure and classmate support, and the moderating role of family SES and country-level income inequality. Using data from adolescents aged 11-15 from 44 countries, participating in the 2017/2018 Health Behaviour in School-aged Children (HBSC) study (N = 202,202), we employed multilevel regression models with cross-level interactions. School SES was operationalized as the average family affluence of adolescents within a school and psychological complaints (e.g., feeling low/depressed) were used as an indication of internalizing problems. On average across countries, adolescents in higher SES schools reported more psychological complaints, with a large effect size. However, differences in this association were observed across countries, with a positive association in 19 out of 44 countries, a negative association in one country, and nonsignificant associations in the remaining countries. Schoolwork pressure partially mediated the average association between school SES and psychological complaints, as school SES was positively associated with schoolwork pressure which was associated with more psychological complaints. Our results did not support the mediating role of classmate support. Also, we found a moderating effect of family SES, indicating a stronger positive association between school SES and psychological complaints for those with a below average family SES compared to those with an average and above average family SES. No moderating effect was observed for country-level income inequality. These findings suggest that adolescents with low family SES attending higher SES schools are especially at risk for psychological complaints, and may therefore require tailored support. A promising strategy to reduce psychological complaints entails addressing schoolwork pressure.

The Relation between Residential Mobility and Internalizing and Externalizing Problems in Adolescence: The Role of Subjective Moving Experience, Gender, and Friendship Quality.

Adolescent residential mobility can be a stressful life event, potentially aggravating internalizing or externalizing problems. However, the longitudinal effects of residential mobility are understudied and may be context-dependent. This study investigates the longitudinal associations between adolescent residential mobility and internalizing and externalizing problems. Additionally, this study examines for whom residential moves are most detrimental by including subjective moving experience, gender, and friendship quality before the move as moderators. Longitudinal data from 2,029 adolescents (51% female) from the TRacking Adolescents' Individual Lives Survey (TRAILS) were used (Mage [SD] at T1 = 11.1 [0.55], T2 = 13.6 [0.52], and T3 = 16.3 [0.70]). Results from stepwise multi-level random-effect models showed that adolescents who experienced an unpleasant move remained stable in internalizing problems, while others decreased over time. Adolescents who moved increased stronger in externalizing problems than adolescents who did not move, independent of whether they experienced the move as unpleasant. Gender and friendship quality before the move did not moderate the relation between residential mobility and internalizing or externalizing problem development. These results emphasize that residential moves in adolescence, especially when experienced as unpleasant, can have long-lasting negative effects on adolescent development.

Country-level sociocultural context and socioeconomic inequalities in adolescent dietary behaviours: A multilevel analysis in 21 European countries.

Studies to date have predominantly focused on countries' socioeconomic conditions (e.g., income inequality) to explain cross-national differences in socioeconomic inequalities in adolescent health (behaviours). However, the potential explanatory role of sociocultural contexts at country-level remains underexamined. This study examined whether the country-level sociocultural context and changes thereof were associated with adolescent socioeconomic inequalities in dietary behaviours. International comparative data of 344,352 adolescents living in 21 countries participating in 2002, 2006, 2010 and 2014 waves of the Health Behaviour in School-aged Children (HBSC) survey were combined with aggregated levels of openness-to-change from the European Social Survey (ESS). Four dietary behaviours (i.e., fruit, vegetable, sweets and soft drink consumption) and two measures of socioeconomic status (SES) on the individual level (i.e., family affluence scale [FAS] and occupational social class [OSC]) were studied. Multilevel logistic regression analyses returned contrasting results for the two SES measures used. In countries with higher levels of openness-to-change, smaller FAS inequalities in daily fruit, sweets and soft drink consumption were observed, but no such inequalities were found for vegetable consumption. Conversely, in these countries, larger OSC inequalities in soft drink consumption were found. Country-specific changes in openness-to-change over time were not associated with the magnitude of adolescent dietary inequalities. Findings underscore the importance of including country-level sociocultural contexts to improve the understanding of cross-national differences in socioeconomic inequalities in adolescents' diets. Future studies, spanning a longer timeframe, are required to examine whether such associations exist within countries over time since our timeframe might have been too small to capture these long-term trends.

Dynamic Associations Between Anxiety Symptoms and Drinking Behavior From Early Adolescence to Young Adulthood.

PURPOSE: Research is inconclusive with respect to the possible risk-increasing effect of anxiety symptoms on heavy drinking behavior among adolescents and young adults. Adult role transitions and changes in the social context from early adolescence into young adulthood may impact the association between anxiety symptoms and alcohol use. METHODS: The TRacking Adolescents' Individual Lives Survey, including 2,229 individuals at baseline, was used to evaluate the bi-directional and longitudinal associations between anxiety symptoms and alcohol use, using data at 14, 16, 19, 22, and 25 years of age. RESULTS: Cross-lagged models revealed a relatively stable negative association at 14, 16, and 19 years, showing that relatively higher anxiety symptoms were associated with relatively lower drinking levels three years later. This effect was absent in young adulthood. There was no evidence for significant associations between alcohol use and subsequent anxiety symptoms, with the exception of alcohol use at age 19, which predicted relatively lower levels of anxiety symptoms at age 22. DISCUSSION: Overall, the results indicated that anxiety symptoms may withhold adolescents from (heavy) drinking, although this protective effect disappeared in young adulthood. Transitions in social contexts as well as autonomy and adult responsibilities could underlie the changing association between alcohol use and anxiety symptoms throughout adolescence and young adulthood.

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 profiles in peer and family social support, online contacts, and preferences for online communication. Then we assessed the association between sexual attraction and profile membership. A five-profile solution fitted the data best. Profiles were characterized as high support, online contact, and average online communication preference (35.6%); high support, low online contact, and weak online communication preference (42.9%); average support, high online contact, and strong online communication preference (9.9%); low support, low online contact, and average online communication preference (6.9%); and low support, average online contact, and average online communication preference (5.0%). Same- and both-sex attracted adolescents had higher odds than other-sex attracted adolescents of being in the latter three profiles than in the first profile. Thus, same- and both-sex attracted adolescents were more likely to report average to low rates of peer and family social support, high to low frequency of online contact, and an average to strong preference for online communication than other-sex attracted adolescents. The average to low levels of support especially influenced these sexual orientation-based differences in profile membership.

Trends and the Gender Gap in the Reporting of Sexual Initiation Among 15-Year-Olds: A Comparison of 33 European Countries.

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 these could be attributed to gender inequality and gender role attitudes. To answer these questions, we combined individual-level data from the international Health Behaviour in School-aged Children study collected in 2010 (N = 57,656), 2014 (N = 56,745) and 2018 (N = 55,127) with country-level data on gender inequality and gender role attitudes. We found a decrease over time in early sexual initiation in most countries, but also cross-country differences in these trends. More boys than girls reported sexual initiation in 2018. This gender gap also varied across countries and slightly decreased over time. In countries with less progressive gender role attitudes and more gender inequality, fewer girls reported early sexual initiation, resulting in a larger gender gap in these countries. To conclude, policy makers, healthcare providers and educators should focus on changing stereotypical gender norms.

Sexual Attraction Disparities in Adolescent Mental Health: The Role of School Norms.

Purpose: Few studies examine whether and how heterosexist norms in schools might influence disparities in mental health between sexual minority and heterosexual adolescents. Addressing this gap, we study disparities in life satisfaction, psychosomatic complaints, and emotional problems between same/both-sex attracted and other-sex attracted adolescents and examine the moderating role of heterosexist norms on the classroom- and school-level. Methods: We used data from the 2013 and 2017 Dutch Health and Behavior in School-Aged Children study (N = 12,756; mean age = 14.02; standard deviation = 1.54). Separate multi-level analyses for life satisfaction, psychosomatic complaints, and emotional problems were conducted in which cross-level interaction effects between sexual attraction and school and classroom-level heterosexist norms were estimated. Results: Same-sex attracted, both-sex attracted, and adolescents unsure about their sexual attraction reported lower life satisfaction, more psychosomatic complaints, and more emotional problems than their other-sex attracted peers. On average, stronger school-level heterosexist norms were associated with higher life satisfaction, fewer psychosomatic complaints, and fewer emotional problems. Stronger classroom-level heterosexist norms were associated with fewer emotional problems. One moderating effect of sexual attraction and school-level heterosexist norms was found. Contrary to expectations, disparities in life satisfaction between same-sex attracted and other-sex attracted adolescents were smaller when classroom-level heterosexist norms were stronger. Standardized regression coefficients showed that the associations were small. Conclusion: Although our findings suggest pressing health disparities between heterosexual and sexual minority adolescents, heterosexist norms at the school and classroom level were weakly associated with these health disparities.

Time trends in associations between neighbourhood and school characteristics and mental health problems among Dutch adolescents.

We investigated trends in associations between physical and social neighbourhood and school characteristics and adolescent mental health problems between 2005 and 2017. Nationally representative, repeated cross-sectional data collected in the Netherlands among primary (N = 5,871) and secondary school students (N = 20,778) were analysed through cross-classified multilevel models. Hardly any evidence was found for over-time changes in associations between neighbourhood and school characteristics and adolescent mental health problems. Findings showed that for both groups of students, only social characteristics within the two contexts were associated with adolescent mental health problems. For secondary school students, school effects were larger than neighbourhood effects, while the opposite was true for primary school students. Specifically, primary school students residing in more socially fragmented or lower socioeconomic status (SES) neighbourhoods, and lower SES schools, reported more conduct problems and peer relationship problems. For secondary school students, only the SES of the neighbourhood and the school was associated with all four aspects of mental health problems. Remarkably, the direction of the associations between neighbourhood/ school SES and adolescent mental health problems varied across the different mental health outcomes. More research is warranted to replicate our findings.

Examining the role of civic attitudes in the link between family wealth and school dropout among tertiary vocational students.

This study examined the relationship between family wealth and school dropout among vocational education students (n = 1,231; mean age=17.81). It investigated whether (1) family affluence and adolescents' own perceptions and experiences of their family wealth (i.e., perceived family wealth, financial scarcity) predict dropout, (2) adolescents' civic attitudes (i.e., system justification, institutional trust) explain the association between family wealth and school dropout, and (3) trust in teachers buffers against the risk of dropout among students with lower civic attitudes. Multivariate models revealed that financial scarcity predicted dropout. Financial scarcity showed an indirect only effect on dropout through lower institutional trust, but not through system justification. Trust in teachers was neither associated with dropout, nor a moderator. Controlling for mental health problems did not affect these results. This study helps explain how students' experienced and perceived family wealth can affect their educational attainment, by reducing their trust in social institutions.

Disentangling the interplay between genes, cognitive skills, and educational level in adolescent and young adult smoking - The TRAILS study.

Recent studies suggest that smoking and lower educational attainment may have genetic influences in common. However, little is known about the mechanisms through which genetics contributes to educational inequalities in adolescent and young adult smoking. Common genetic liabilities may underlie cognitive skills associated with both smoking and education, such as IQ and effortful control, in line with indirect health-related selection explanations. Additionally, by affecting cognitive skills, genes may predict educational trajectories and hereby adolescents' social context, which may be associated with smoking, consistent with social causation explanations. Using data from the Dutch TRAILS Study (N = 1581), we estimated the extent to which polygenic scores (PGSs) for ever smoking regularly (PGSSMOK) and years of education (PGSEDU) predict IQ and effortful control, measured around age 11, and whether these cognitive skills then act as shared predictors of smoking and educational level around age 16, 19, 22, and 26. Second, we assessed if educational level mediated associations between PGSs and smoking. Both PGSs were associated with lower effortful control, and PGSEDU also with lower IQ. Lower IQ and effortful control, in turn, predicted having a lower educational level. However, neither of these cognitive skills were directly associated with smoking behaviour after controlling for covariates and PGSs. This suggests that IQ and effortful control are not shared predictors of smoking and education (i.e., no indirect health-related selection related to cognitive skills). Instead, PGSSMOK and PGSEDU, partly through their associations with lower cognitive skills, predicted selection into a lower educational track, which in turn was associated with more smoking, in line with social causation explanations. Our findings suggest that educational differences in the social context contribute to associations between genetic liabilities and educational inequalities in smoking.

Longitudinal associations of neighbourhood environmental exposures with mental health problems during adolescence: Findings from the TRAILS study.

BACKGROUND: Cross-sectional studies have found associations between neighbourhood environments and adolescent mental health, but the few longitudinal studies mainly focused on single exposure-based analyses and rarely assessed the mental health associations with environmental changes. OBJECTIVES: We assessed longitudinal within- and between-person associations of multiple neighbourhood time-varying physical and social environmental exposures with externalising and internalising problems throughout adolescence. METHODS: We used four waves of TRAILS (Tracking Adolescents' Individual Lives Survey) data on self-reported externalising and internalising problems at ages 11, 13, 16, and 19 among 2,135 adolescents in the Netherlands. We measured residence-based time-varying environmental exposures, including green space, air pollution (fine particulate matter (PM2.5)), noise, deprivation, and social fragmentation. We fitted random-effect within-between regression models to assess the environment-mental health associations. RESULTS: At the within-person level, an interquartile range (IQR) increase in PM2.5 was associated with a 0.056 IQR (95% CI: 0.014, 0.099) increase in externalising problems, while an IQR social fragmentation increase was associated with a 0.010 IQR (95% CI: -0.020, -0.001) decrease in externalising problems. Stratification revealed that the association with PM2.5 was significant only for movers, whereas the association with social fragmentation remained only for non-movers. At the between-person level, an IQR higher noise was associated with a 0.100 IQR (95% CI: 0.031, 0.169) more externalising problems, while higher deprivation (ß = 0.080; 95% CI: 0.022, 0.138) and lower fragmentation (ß = -0.073; 95% CI: -0.128, -0.018) were associated with more internalising problems. We also observed positive between-person associations between PM2.5, noise, and internalising problems, but both associations were unstable due to the high PM2.5-noise correlation. Further, we observed a non-linear between-person PM2.5-externalising problems association turning positive when PM2.5 > 15 µg/m3. Null associations were found for green space. CONCLUSION: Our findings suggested that air pollution, noise, and neighbourhood deprivation are risk factors for adolescent mental health. Not only exposure levels but also exposure changes matter for adolescent mental health.

Decline in positive future orientations among adolescents during covid-19: The role of socioeconomic status, parental support, and sense of control.

INTRODUCTION: Before coronavirus disease (covid-19), adolescents from a lower socioeconomic status (SES) background tend to have less positive future orientations, receive less parental support, and have a weaker sense of control than adolescents from a higher SES background. The covid-19 pandemic has potentially increased the socioeconomic gaps in positive future orientations, parental support, and sense of control among adolescents who are currently in vocational education. As societies are aiming to return back to precovid norms, certain groups of adolescents might require more attention for ensuring a stable future than others. METHODS: Two-wave questionnaire data of 689 Dutch adolescents (Mage = 17.8; 56% female) from the Youth Got Talent project was analyzed. Latent Change Score models are a relatively novel approach that allows two-wave data to estimate associations between precovid predictor variables and changes in outcome variables from before to during covid-19 (e.g., SES, positive future orientations, parental support, and sense of control). Analyses were preregistered. RESULTS: The precovid socioeconomic differences in adolescent's positive future orientations and sense of control remained stable during covid-19, whereas the socioeconomic difference in parental support decreased during covid-19. A decline in parental support, an increase in sense of control, and more covid-19 hardships were associated with an increase in future orientations. CONCLUSION: The covid-19 situation has not substantially increased socioeconomic differences in positive future orientations and sense of control, but did decrease socioeconomic differences in parental support among adolescents. Short-term policies should aim to facilitate parental support and positive future orientations to all adolescents who experienced a decline, while also long-term focusing on the more consistent socioeconomic difference in sense of control among adolescents.

A cross-sectional study on gaming intensity and social vulnerability in adolescents that have a chronic condition.

Background: Adolescents growing up with a chronic condition might experience more social vulnerabilities compared to their healthy peers as an indirect result of their conditions. This can lead to a relatedness need frustration for these adolescents. Consequently, they might spend more time playing video games compared to their peers. Research shows that both social vulnerability and gaming intensity are predictors for problematic gaming. Therefore, we investigated if social vulnerability and gaming intensity are more pronounced in adolescents that have a chronic condition compared to the general population; and if these levels reflect the levels of a clinical group being treated for Internet Gaming Disorder (IGD). Methods: Data on peer problems and gaming intensity were compared from three separate samples: a national representative sample of adolescents, a clinical sample of adolescents that are undergoing treatment for IGD, and a sample of adolescents diagnosed with a chronic condition. Results: No differences were found on either peer problems or gaming intensity between the group of adolescents that have chronic conditions and the national representative group. The group with chronic conditions scored significantly lower on gaming intensity than the clinical group. No significant differences were found between these groups on peer problems. We repeated the analyses for boys only. Similar results were found for the group with chronic conditions compared to the national representative group. The group with chronic conditions now scored significantly lower on both peer problems and gaming intensity than the clinical group. Conclusion: Adolescents growing up with a chronic condition appear similar in their gaming intensity and peer problems compared to their healthy peers.

Self-reported quantity and quality of sleep in children and adolescents with a chronic condition compared to healthy controls.

To assess self-reported quantity and quality of sleep in Dutch children with a chronic condition compared to healthy controls and to the recommended hours of sleep for youth. Sleep quantity and quality were analyzed in children with a chronic condition (cystic fibrosis, chronic kidney disease, congenital heart disease, (auto-)immune disease, and medically unexplained symptoms (MUS); n = 291; 15 ± 3.1 years, 63% female. A subset of 171 children with a chronic condition were matched to healthy controls using Propensity Score matching, based on age and sex, ratio 1:4. Self-reported sleep quantity and quality were assessed with established questionnaires. Children with MUS were analyzed separately to distinguish between chronic conditions with and without an identified pathophysiological cause. Generally, children with a chronic condition met the recommended amount of sleep, however 22% reported poor sleep quality. No significant differences in sleep quantity and quality were found between the diagnosis groups. Children with a chronic condition and with MUS slept significantly more than healthy controls at ages 13, 15, and 16. Both at primary and secondary school, poor sleep quality was least frequent reported in children with a chronic condition and most often reported in children with MUS.  Conclusion: Overall, children with chronic conditions, including MUS, met the recommended hours of sleep for youth, and slept more than healthy controls. However, it is important to obtain a better understanding of why a substantial subset of children with chronic conditions, mostly children with MUS, still perceived their sleep quality as poor. What is Known: • According to the Consensus statement of the American Academy of Sleep medicine, typically developing children (6 to 12 years) should sleep 9 to 12 h per night, and adolescents (13 to 18 years) should sleep 8 to 10 h per night. • Literature on the optimal quantity and quality of sleep in children with a chronic condition is very limited. What is New: Our findings are important and provide novel insights: • In general, children with a chronic condition sleep according to the recommended hours of sleep. • A substantial subset of children with chronic conditions, perceived their sleep quality as poor. Although this was reported mostly by children with medically unexplained symptoms (MUS), the found poor sleep quality was independent of specific diagnosis.

ADHD Symptoms and Educational Level in Adolescents: The Role of the Family, Teachers, and Peers.

Few studies have explored the contribution of family and school factors to the association between ADHD symptoms and lower education. Possibly, having more ADHD symptoms contributes to poorer family functioning and less social support, and consequently a lower educational level (i.e., mediation). Moreover, the negative effects of ADHD symptoms on education may be stronger for adolescents with poorer family functioning or less social support (i.e., interaction). Using data of the Dutch TRAILS Study (N = 2,229), we evaluated associations between ADHD symptoms around age 11 and educational level around age 14, as well as between ADHD symptoms around age 14 and 16 years and subsequent changes in educational level around age 16 and 19, respectively. We assessed the potential mediating role of family functioning, and social support by teachers and classmates, all measured around ages 11, 14, and 16, while additionally evaluating interactions between ADHD symptoms and these hypothesized mediators. ADHD symptoms were associated with poorer family functioning, less social support by teachers and classmates, and lower education throughout adolescence. No conclusive evidence of mediation was found, because unique associations between family functioning and social support by teachers and classmates and education were largely absent. Furthermore, we found no interactions between ADHD symptoms and family functioning and social support by teachers and classmates. Although social support by teachers and classmates and good family functioning may benefit the wellbeing and mental health of adolescents with high levels of ADHD symptoms, they will not necessarily improve their educational attainment.

The role of social cognitions in the social gradient in adolescent mental health: A longitudinal mediation model.

The social gradient in adolescent mental health is well established: adolescents' socioeconomic status is negatively associated with their mental health. However, despite changes in social cognition during adolescence, little is known about whether social cognitions mediate this gradient. Therefore, this study tested this proposed mediational path using three data waves, each 6 months apart, from a socioeconomically diverse sample of 1,429 adolescents (Mage = 17.9) in the Netherlands. Longitudinal modeling examined whether three social cognitions (self-esteem, sense of control, and optimism) mediated associations between perceived family wealth and four indicators of adolescent mental health problems (emotional symptoms, conduct problems, hyperactivity, and peer problems). There was evidence of a social gradient: adolescents with lower perceived family wealth reported more concurrent emotional symptoms and peer problems and an increase in peer problems 6 months later. Results also showed evidence of mediation through social cognitions, specifically sense of control: adolescents with lower perceived family wealth reported a decrease in sense of control (though not self-esteem nor optimism) 6 months later, and lower sense of control predicted increases in emotional symptoms and hyperactivity 6 months later. We found concurrent positive associations between perceived family wealth and all three social cognitions, and concurrent negative associations between social cognitions and mental health problems. The findings indicate that social cognitions, especially sense of control, may be an overlooked mediator of the social gradient in adolescent mental health.

When Too Much Help is of No Help: Mothers' and Fathers' Perceived Overprotective Behavior and (Mal)Adaptive Functioning in Adolescents.

Although parental overprotection is theorized to have lasting negative effects throughout a child's life, there is limited empirical evidence available on its long-term significance on adolescent well-being. This preregistered, three-wave longitudinal study investigated the association of maternal and paternal perceived overprotection in early adolescence with the development of (mal)adaptive psychological, academic, and social functioning throughout adolescence. Data (N = 2229; 50.7% girls) from the longitudinal TRacking Adolescents' Individual Lives Survey (TRAILS) in the Netherlands were used (Mage T1 = 11.11, T2 = 13.57, T3 = 16.28). At T1, adolescents reported on their mothers' and fathers' overprotection. From T1 to T3 adolescents and teachers reported about internalizing problems, academic achievement, prosocial, and antisocial behavior. The results showed concurrent associations between higher levels of perceived overprotection and higher levels of internalizing problems, antisocial behaviors, and (after controlling for parental warmth and rejection) lower levels of academic achievement. Perceived overprotection was positively associated with decreased internalizing problems over time. This longitudinal association disappeared after controlling for baseline levels of internalizing problems, suggesting that this result was less robust than expected. Mothers and fathers did not differ in their associations between perceived overprotection and (mal)adaptive functioning. The findings showed that perceived overprotection is mainly concurrently associated with (mal)adaptive adolescent functioning. Future research recommendations are discussed in terms of stability and bidirectional relations.

The social gradient in adolescent mental health: mediated or moderated by belief in a just world?

PURPOSE: A social gradient in adolescent mental health exists: adolescents with higher socioeconomic status (SES) have fewer mental health problems than their peers with lower SES. Little is known about whether adolescents' societal beliefs play a role in this social gradient. Belief in a just world (BJW) may be a mediator or moderator of the social gradient in adolescent mental health. METHODS: Using data from 848 adolescents (Mage = 17) in the Netherlands, path analyses examined whether two indicators of BJW (general and personal) mediated or moderated the associations between two indicators of SES (family affluence and perceived family wealth), and four indicators of adolescent mental health problems (emotional symptoms, conduct problems, hyperactivity, and peer problems). RESULTS: Adolescents with lower family affluence and lower perceived family wealth reported more emotional symptoms, and the association between perceived family wealth and emotional symptoms was mediated by lower personal and general BJW. Furthermore, higher personal BJW amplified the negative association between SES and peer problems. CONCLUSION: This study suggests BJW may both mediate and amplify the social gradient in adolescent mental health. Adolescents' beliefs about society may be important to include in research aimed at understanding this social gradient.

Educational level, attention problems, and externalizing behaviour in adolescence and early adulthood: the role of social causation and health-related selection-the TRAILS study.

Social causation and health-related selection may contribute to educational differences in adolescents' attention problems and externalizing behaviour. The social causation hypothesis posits that the social environment influences adolescents' mental health. Conversely, the health-related selection hypothesis proposes that poor mental health predicts lower educational attainment. From past studies it is unclear which of these mechanisms predominates, as attention problems and externalizing behaviour have the potential to interfere with educational attainment, but may also be affected by differences in the educational context. Furthermore, educational gradients in mental health may reflect the impact of 'third variables' already present in childhood, such as parental socioeconomic status (SES), and IQ. We investigated both hypotheses in relation to educational differences in externalizing behaviour and attention problems throughout adolescence and young adulthood. We used data from a Dutch cohort (TRAILS Study; n = 2229), including five measurements of educational level, externalizing behaviour, and attention problems from around age 14-26 years. First, we evaluated the directionality in longitudinal associations between education, externalizing behaviour, and attention problems with and without adjusting for individual differences using fixed effects. Second, we assessed the role of IQ and parental SES in relation to attention problems, externalizing behaviour, and educational level. Attention problems predicted decreases in education throughout all of adolescence and young adulthood. Differences in parental SES contributed to increases in externalizing behaviour amongst the lower educational tracks in mid-adolescence. Childhood IQ and parental SES strongly predicted education around age 14. Parental SES, but not IQ, also predicted early adolescent attention problems and externalizing behaviour. Our results provide support for the health-related selection hypothesis in relation to attention problems and educational attainment. Further, our results highlight the role of social causation from parental SES in determining adolescent educational level, attention problems, and externalizing behaviour.

Examining socioeconomic disparities in changes in adolescent mental health before and during different phases of the coronavirus disease 2019 pandemic.

This study examined socioeconomic disparities in changes in adolescent mental health between fall 2019 (pre-COVID-19), spring 2020 (initial coronavirus disease 2019 (COVID-19) phase), and fall 2020 (prevailing COVID-19 phase). Using data from 1429 adolescents (Mage  = 17.9) from tertiary vocational schools in the Netherlands with n = 386 participating in all three waves, linear and latent basis growth curve models were assessed and multigroup analyses conducted. Results showed a small but significant decrease in life satisfaction and small but significant increases in emotional problems, peer relationship problems, conduct problems, and hyperactivity-inattention problems. For emotional problems and peer relationship problems, increases between pre-COVID-19 and the initial COVID-19 phase were more pronounced than increases between the initial and prevailing COVID-19 phase. In contrast, linear decreases were found for life satisfaction and linear increases for conduct problems and hyperactivity-inattention problems over the course of the study. Mental health patterns were largely comparable for adolescents from families with varying socioeconomic status.
