No gene by stressful life events interaction on individual differences in adults' self-control.

Background: Difficulty with self-control, or the ability to alter impulses and behavior in a goal-directed way, predicts interpersonal conflict, lower socioeconomic attainments, and more adverse health outcomes. Etiological understanding, and intervention for low self-control is, therefore, a public health goal. A prominent developmental theory proposes that individuals with high genetic propensity for low self-control that are also exposed to stressful environments may be most at-risk of low levels of self-control. Here we examine if polygenic measures associated with behaviors marked by low self-control interact with stressful life events in predicting self-control. Methods: Leveraging molecular data from a large population-based Dutch sample (N = 7,090, Mage = 41.2) to test for effects of genetics (i.e., polygenic scores for ADHD and aggression), stressful life events (e.g., traffic accident, violent assault, financial problems), and a gene-by-stress interaction on self-control (measured with the ASEBA Self-Control Scale). Results: Both genetics (ß =.03 -.04, p <.001) and stressful life events (ß = .11 -.14, p <.001) were associated with individual differences in self-control. We find no evidence of a gene-by-stressful life events interaction on individual differences in adults' self-control. Conclusion: Our findings are consistent with the notion that genetic influences and stressful life events exert largely independent effects on adult self-control. However, the small effect sizes of polygenic scores increases the likelihood of null results. Genetically-informed longitudinal research in large samples can further inform the etiology of individual differences in self-control from early childhood into later adulthood and its downstream implications for public health.

A dyadic perspective on parent-child dyadic coping in children with a chronic condition.

OBJECTIVE: In this study, we examined the extent to which parents and their children with a chronic condition communicate their stress to one another and whether stress communication is associated with different forms of dyadic coping. METHODS: In a sample of 239 parent-child dyads, self-reported stress communication and different forms of perceived dyadic coping (i.e., emotion-oriented, problem-oriented, and negative dyadic coping) were assessed using a cross-sectional design. RESULTS: We first found that children's stress communication was positively associated with more positive (r = 0.28, p < .001) and less negative dyadic coping responses by children (r = -0.22, p < .001). Children's stress communication was also associated with more positive (r = 0.52, r = 0.45, p's < 0.001), and less negative dyadic coping responses by parents (r = -0.19, p < .001). Using dyadic data of children with a chronic condition and their parents, we found that more stress communication of children was associated with healthier coping responses of both children (perceived emotion-oriented dyadic coping: ß = 0.23, p < .001) and parents (perceived emotion-oriented dyadic coping: ß = 0.33, p < .001; perceived problem-oriented dyadic coping: ß = 0.22, p < .001). CONCLUSION: This underscores the importance of communication and adaptive coping strategies of parents and children in the context of a child's chronic condition. These findings may help us find ways to support children and their parents to optimally communicate about and deal with their stress.

Towards a more comprehensive understanding of PTSD and parenting.

BACKGROUND: The impact of post-traumatic stress disorder (PTSD) on parenting and the parent-child relationship has been well-documented in the scientific literature. However, some conceptual and methodological challenges within this research field remain. PROCEDURE: We reflect on a number of challenges that we identified while examining the literature in preparation of an individual participant data meta-analysis on the relationships between PTSD and parenting. FINDINGS: We address 1) the presence of 'trauma-islands'; 2) the need for transdiagnostic theoretical frameworks for mechanisms between PTSD and parenting; 3) the lack of developmental perspectives; 4) the overuse of self-reported retrospective measures; 5) the need to study more diverse samples and cultural contexts; and 6) the lack of research on resilience and post-traumatic growth in parenting. Based on these reflections, we offer suggestions on strategies for responding to these challenges through: 1) welcoming open science; 2) working towards shared theoretical frameworks; 3) doing more longitudinal research 4) expanding the methodological palette; 5) centering lived experience; and 6) taking systemic inequality into account. CONCLUSION: With this commentary, we aim to open a discussion on next steps towards a more comprehensive understanding of the association between PTSD and parenting, and inspire collaborative research.

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.

How Specific is Alcohol-Specific Self-Control? A Longitudinal Study of the Mediating Role of Alcohol-Specific Self-Control in the Relation Between General Self-Control and Adolescent Alcohol Use.

Although accumulating studies indicate that alcohol-specific self-control can be useful in predicting adolescent alcohol use, little is known about its specificity. This longitudinal study aimed to advance our understanding of domain-specific self-control by examining whether alcohol-specific self-control mediates the effect of general self-control on adolescent alcohol use or has generalizing effects by also mediating the effect of general self-control on other behavior requiring self-control (adolescent digital media use and smoking). Data from 906 adolescents aged 11-14 years who were enrolled in the Dutch study Prevention of Alcohol Use in Students were used. Data were collected using online questionnaires at four annual measurements. Structural equation modelling revealed that higher alcohol-specific self-control fully mediated the effect of higher general self-control on alcohol use. Alcohol-specific self-control did not mediate the effect of higher general self-control on digital media use, but did partially mediate the effect of higher general self-control on smoking. These results suggest that alcohol-specific self-control is domain-specific, but not necessarily substance-specific. The domain-specificity of alcohol-specific self-control provides evidence for its theoretical relevance for the explanation of adolescent alcohol use. It also suggests leverage points for intervention programs focusing on improving alcohol-specific self-control to reduce adolescent alcohol use.

Defining and Measuring Resilience in Children with a Chronic Disease: a Scoping Review.

More than 25% of all children grow up with a chronic disease. They are at higher risk for developmental and psychosocial problems. However, children who function resiliently manage to adapt positively to these challenges. We aim to systematically review how resilience is defined and measured in children with a chronic disease. A search of PubMed, Cochrane, Embase, and PsycINFO was performed on December 9, 2022, using resilience, disease, and child/adolescent as search terms. Two reviewers independently screened articles for inclusion according to predefined criteria. Extraction domains included study characteristics, definition, and instruments assessing resilience outcomes, and resilience factors. Fifty-five out of 8766 articles were identified as relevant. In general, resilience was characterized as positive adaptation to adversity. The included studies assessed resilience by the outcomes of positive adaptation, or by resilience factors, or both. We categorized the assessed resilience outcomes into three groups: personal traits, psychosocial functioning, and disease-related outcomes. Moreover, myriad of resilience factors were measured, which were grouped into internal resilience factors (cognitive, social, and emotional competence factors), disease-related factors, and external factors (caregiver factors, social factors, and contextual factors). Our scoping review provides insight into the definitions and instruments used to measure resilience in children with a chronic disease. More knowledge is needed on which resilience factors are related to positive adaptation in specific illness-related challenges, which underlying mechanisms are responsible for this positive adaptation, and how these underlying mechanisms interact with one another.

Study protocol: development and randomized controlled trial of a preventive blended care parenting intervention for parents with PTSD.

BACKGROUND: Children of parents with post-traumatic stress disorder (PTSD) are at increased risk of adverse psychological outcomes. An important risk mechanism is impaired parental functioning, including negative parenting behavior, perceived incompetence, and lack of social support. Several parenting interventions for trauma-exposed parents and parents with psychiatric disorders exist, but none have specifically targeted parents with PTSD. Our objective is to evaluate the effectiveness of a blended care preventive parenting intervention for parents with PTSD. METHODS: The intervention was adapted from an existing online intervention, KopOpOuders Self-Help. In co-creation with parents with PTSD and partners, the intervention was adapted into KopOpOuders-PTSD, by adding PTSD-specific content and three in-person-sessions with a mental health prevention professional. Effectiveness will be tested in a randomized controlled trial among N = 142 parents being treated for PTSD at Arkin Mental Health Care (control condition: treatment as usual, n = 71; intervention condition: treatment as usual + intervention, n = 71). Online questionnaires at pretest, posttest, and three-month follow-up and ecological momentary assessment at pretest and posttest will be used. Intervention effects on primary (parenting behavior) and secondary outcomes (perceived parenting competence, parental social support, parenting stress, child overall psychological problems and PTSD symptoms) will be analyzed using generalized linear mixed modeling. We will also analyze possible moderation effects of parental PTSD symptoms at pretest on primary and secondary outcomes. DISCUSSION: This study protocol describes the randomized controlled trial of KopOpOuders-PTSD, a blended care preventive parenting intervention for parents with PTSD. Findings can contribute to understanding of the effectiveness of parenting support in clinical practice for PTSD. TRIAL REGISTRATION: This protocol (Version 1) was registered on 11-02-2022 at ClinicalTrials.gov under identification number NCT05237999.

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.

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.

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.

Parental Conflicts and Posttraumatic Stress of Children in High-Conflict Divorce Families.

Parental conflicts consistently predict negative outcomes for children. Research suggests that children from high-conflict divorces (HCD) may also experience post-traumatic stress symptoms (PTSS), yet little is known about the association between parental conflicts in HCD families and child PTSS. We investigated this association, hypothesizing that parental conflicts would predict child PTSS. We also tested the moderating role of interparental contact frequency, hypothesizing that frequent contact would intensify the association between parental conflicts and child PTSS. This study was part of an observational study on the outcomes of No Kids in the Middle (NKM), a multi-family group intervention for HCD families. A total of 107 children from 68 families participated in the study with at least one parent. We used pre- (T1) and post-intervention (T2) data. Research questions were addressed cross-sectionally, using regression analyses to predict PTSS at T1, and longitudinally, using a correlated change (T1 to T2) model. The cross-sectional findings suggested that mother- and child-reported conflicts, but not father-reported conflicts, were related to the severity of child PTSS. Longitudinally, we found that change in father-reported conflicts, but not change in child- or mother-reported conflicts, were related to change in child PTSS. The estimated associations for the different informants were not significantly different from one another. The frequency of contact between ex-partners did not moderate the relationship between parental conflicts and child PTSS. We conclude that there is a positive association between parental conflicts and child PTSS in HCD families independent of who reports on the conflicts.

Tracking Mental Wellbeing of Dutch Adolescents During the First Year of the COVID-19 Lockdown: A Longitudinal Study.

PURPOSE: Adolescents might be susceptible to the effects of the COVID-19 lockdown. We assessed changes in mental wellbeing throughout the first year of the pandemic and compared these with prepandemic levels. METHODS: This five-wave prospective study among Dutch adolescents aged 12-17 years used data collected before the pandemic (n = 224) (T0), in May (T1), July (T2), and October 2020 (T3), and in February 2021 (T4). Generalized estimating equations were used to assess the association between stringency of the lockdown with mental wellbeing. RESULTS: Adolescents had a lower life satisfaction during the first full lockdown (T1) [adjusted ß: -0.36, 95% confidence interval (CI): -0.58 to -0.13], during the partial lockdown (T3) (adjusted ß: -0.37, 95% CI: -0.63 to -0.12), and during the second full lockdown (T4) (adjusted ß: -0.79, 95% CI: -1.07 to -0.52) compared to before the pandemic (T0). Adolescents reported more internalizing symptoms during only the second full lockdown (T4) (adjusted ß: 2.58, 95% CI: 0.41-4.75). During the pandemic [at T1 (adjusted ß: 0.29, 95% CI: 0.20-0.38), T2 (adjusted ß: 0.36, 95% CI: 0.26-0.46), T3 (adjusted ß: 0.33, 95% CI: 0.22-0.45), and T4 (adjusted ß: 0.20, 95% CI: 0.07-0.34)], adolescents reported a better psychosomatic health, partly attributable to less trouble falling asleep (p < .01). DISCUSSION: The COVID-19 lockdown measures have had both a negative and positive impact on mental wellbeing of Dutch adolescents. However, mental wellbeing was most impacted during the second full lockdown compared to before the pandemic.

The Association Between Child Maltreatment and Loneliness Across the Lifespan: A Systematic Review and Multilevel Meta-Analysis.

While there is evidence that child maltreatment is positively associated with loneliness, the strength of this association is not yet clear. It is also unclear whether the magnitude and statistical significance of this association varies across groups of individuals. Therefore, this meta-analysis examines whether there are differences in loneliness between individuals with and without maltreatment histories, and which factors may influence the association between child maltreatment and loneliness. A three-level meta-analysis was conducted on 52 studies reporting 116 effect sizes (N = 1,705,493; Mage = 30.93; 49.6% females). Results showed a medium overall effect (g = 0.45, p < .001, 95% CI [0.36, 0.53]), indicating that individuals with maltreatment histories, on average, feel lonelier than individuals without maltreatment histories. Moderator analyses showed that effect sizes were larger for emotional abuse and emotional neglect as compared to other types of child maltreatment and decreased when participants were older at the time of loneliness assessment. These findings suggest that individuals with maltreatment histories, especially those who have been emotionally abused and/or emotionally neglected, are vulnerable to experiencing loneliness across the lifespan. The results also suggest that feelings of loneliness warrant attention in prevention and intervention programs for individuals with maltreatment histories.

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 the nine-item SMD scale with dichotomous response options. FINDINGS: Confirmatory factor analyses (CFA) showed good model fit for a one-factor model across all countries (minimum comparative fit index (CFI) and Tucker-Lewis index (TLI) = 0.963 and 0.951, maximum root mean square error of approximation (RMSEA) and standardized root mean square residual (SRMR) = 0.057 and 0.060), confirming structural validity. The internal consistency of the items was adequate in all countries (minimum alpha = 0.840), indicating that the scale provides reliable scores. Multi-group CFA showed that the factor structure was measurement invariant across countries (ΔCFI = -0.010, ΔRMSEA = 0.003), suggesting that adolescents' level of problematic SMU can be reliably compared cross-nationally. In all countries, gender and socio-economic invariance was established, and age invariance was found in 43 of 44 countries. In line with prior research, in almost all countries, problematic SMU related to poorer mental wellbeing (range ßSTDY = 0.193-0.924, P < 0.05) and higher intensity of online communication (range ßSTDY = 0.163-0.635, P < 0.05), confirming appropriate criterion validity. CONCLUSIONS: The social media disorder scale appears to be suitable for measuring and comparing problematic social media use among young adolescents across many national contexts.

Psychosocial functioning in adolescents growing up with chronic disease: The Dutch HBSC study.

Many adolescents worldwide (indirectly) grow up with a chronic disease, which may impact their functioning and wellbeing. The objective of this study is to assess whether adolescents with a (family member with a) chronic disease differ from their healthy counterparts in terms of psychosocial functioning. Data from the Dutch 2013 HBSC-survey were used, including 7168 adolescents (Meanage = 13.7, SD = 1.57, 50.5% female). Participants indicated whether they or one of their family members had a long-term (> 3 months) disease or disability (mental/physical) and were categorized into four groups based on disease presence (none, other, self, both). Psychosocial functioning was assessed in terms of life satisfaction, self-rated health, psychosomatic health, mental health problems, support, substance use, physical exercise, screen time, and school liking. Chronically diseased adolescents (n = 162) reported lower life satisfaction, self-rated and psychosomatic health, more mental health problems, lower peer support, more substance use, and less physical exercise compared to healthy peers. Chronically diseased adolescents who also had a family member with a chronic disease (n = 74) showed comparable outcomes on these life domains, although they did not differ from their healthy peers regarding peer support, substance use, and physical activity. Healthy adolescents with a chronically diseased family member (n = 737) reported significantly lower life satisfaction, self-rated and psychosomatic health, more mental health problems, and less family support compared to healthy peers who grew up in healthy families; however, they reported more positive outcomes than adolescents who had a chronic disease themselves.Conclusion: Having a (family member with a) chronic disease is associated with impaired psychosocial functioning on various life domains. Our findings aid in understanding the psychosocial associates of chronic disease and imply that caregivers should be observant of psychosocial problems among vulnerable adolescents to provide appropriate guidance. What is Known: • Adolescents who grow up with a (family member with a) chronic disease encounter numerous challenges that may be related to poorer developmental outcomes on the long term. What is New: • This study adds a comprehensive overview of the psychosocial functioning of adolescents with a (family member with a) chronic disease, as compared to healthy counterparts that grow up in a healthy family.

Validation of the Social Media Disorder Scale in Adolescents: Findings From a Large-Scale Nationally Representative Sample.

Large-scale validation research on instruments measuring problematic social media use (SMU) is scarce. Using a nationally representative sample of 6,626 Dutch adolescents aged 12 to 16 years, the present study examined the psychometric properties of the nine-item Social Media Disorder scale. The structural validity was solid, because one underlying factor was identified, with adequate factor loadings. The internal consistency was good, but the test information was most reliable at moderate to high scores on the scale's continuum. The factor structure was measurement invariant across different subpopulations. Three subgroups were identified, distinguished by low, medium, and high probabilities of endorsing the criteria. Higher levels of problematic SMU were associated with higher probabilities of mental, school, and sleep problems, confirming adequate criterion validity. Girls, lower educated adolescents, 15-year-olds, and non-Western adolescents were most likely to report problematic SMU. Given its good psychometric properties, the scale is suitable for research on problematic SMU among adolescents.

The course of problematic social media use in young adolescents: A latent class growth analysis.

Using four waves of longitudinal data collected in 2015-2019 from 1419 Dutch adolescents (Mage  = 12.5, 45.9% female, 21.9% immigrant), this study identified trajectories of problematic social media use (SMU) in parallel with trajectories of SMU frequency. Latent class growth analysis identified two subgroups with relatively high levels of problematic SMU over time: One showed high (24.7%) and one showed average SMU frequency (15.8%). Also, two subgroups with persistently low levels of problematic SMU were identified: One reported low (22.4%) and one reported high SMU frequency (37.1%). Although both subgroups with high levels of problematic SMU reported low subjective well-being, the group with high SMU frequency showed low self-control, whereas the group with average SMU frequency reported poor social competencies.

Parent-Child Dyadic Coping and Quality of Life in Chronically Diseased Children.

Different forms of dyadic coping are associated with positive outcomes in partner relationships, yet little is known about dyadic coping in parent-child relationships. The current research explored the association between parent-child dyadic coping and children's quality of life in 12-18-year old children with a chronic disease (i.e., cystic fibrosis, autoimmune diseases, and children post-cancer treatment). In a sample of 105 parent-child dyads, self-reported forms of dyadic coping (i.e., stress communication, problem-oriented, emotion-oriented, and negative dyadic coping) and children's quality of life were assessed. Children reported more stress communication and negative dyadic coping than their parents, while parents reported more problem-oriented dyadic coping and emotion-oriented dyadic coping than their children. More stress communication of the child was associated with more emotion-oriented dyadic coping and less negative dyadic coping of the parent. More negative dyadic coping of the child was associated with less stress communication, problem-oriented dyadic coping and emotion-oriented dyadic coping of the parent. Additionally, both children's and parents' negative dyadic coping were associated with lower self-reported pediatric quality of life and parents' emotion-oriented dyadic coping was associated with higher pediatric quality of life. These findings emphasize that children and their parents mutually influence each other and that dyadic coping is associated with children's quality of life. Theoretical and practical implications are discussed.

Gender-Specific Changes in Life Satisfaction After the COVID-19-Related Lockdown in Dutch Adolescents: A Longitudinal Study.

PURPOSE: The purposes of this study were to assess whether mental well-being has changed after introduction of the lockdown measures compared with that before, whether this change differs between boys and girls, and whether this change is associated with COVID-19-related concerns. METHODS: This is a two-wave prospective study among Dutch adolescents using data collected up to one year before the COVID-19 pandemic (n = 224) and 5-8 weeks after the first introduction of lockdown measures (n = 158). Mental well-being was assessed by three indicators: life satisfaction, internalizing symptoms, and psychosomatic health. General linear model repeated-measures analysis of variance was used to assess whether mental well-being has changed and if this differed by sex. Univariate linear regressions were used to assess associations between COVID-19-related concerns and a change in mental well-being. RESULTS: Life satisfaction decreased (η2p = .079, p < .001), but no change in internalizing symptoms was observed (η2p = .014, p = .14), and psychosomatic health increased (η2p = .194, p < .001) after the introduction of lockdown measures. Boys scored significantly better on all mental health indicators compared with girls at baseline and follow-up. However, boys' life satisfaction significantly decreased at the follow-up (η2p = .038, p = .015), whereas girls' life satisfaction did not change. Concerns about COVID-19 were significantly associated with a lower life satisfaction and more internalizing symptoms. CONCLUSIONS: Adolescents', especially boys', life satisfaction decreased during the lockdown. They reported no change in internalizing symptoms and an improved psychosomatic health. Adolescents' mental well-being is expected to vary during the COVID-19 pandemic and should continue to be monitored.

Perceived Social Support from Different Sources and Adolescent Life Satisfaction Across 42 Countries/Regions: The Moderating Role of National-Level Generalized Trust.

Although previous research established a positive association between perceived social support and adolescent life satisfaction, little is known about the relative importance of different sources of support for adolescent life satisfaction and cross-country variations in this respect. Using large-scale representative samples from the 2017/18 Health Behaviour in School-aged Children (HBSC) study, this study examined to what extent the association between social support and life satisfaction in early adolescence varied across different social sources and countries. Also, it examined whether cross-country variations are explained by national-level generalized trust, a sociocultural factor that shapes adolescent socialization. National-level data were linked to data from 183,918 early adolescents (Mage = 13.56, SD = 1.63, 52% girls) from 42 European and North American countries/regions obtained from HBSC. Multilevel regression analyses yielded a positive association between support from different sources and life satisfaction. The strongest associations were found for support from families, followed by teachers and classmates, and weakest for support from friends. Associations varied across different countries/regions. National-level trust amplified the association between perceived classmate support and adolescent life satisfaction. The revealed cross-country differences open avenues for future cross-cultural research on explanations for cross-cultural differences in the association between social support from different sources and life satisfaction in early adolescence.
