Exploring the intersectionality of family SES and gender with psychosocial, behavioural and environmental correlates of physical activity in Dutch adolescents: a cross-sectional study.

Background: Examining the correlates of adolescent's physical activity (PA) and how they may differ according to the intersection of gender and family socioeconomic status (SES) can support the development of tailored interventions to more effectively promote adolescents' PA. This study explored how the associations between psychosocial, behavioural and environmental factors and adolescent's PA differed according to gender and family SES.

Methods: This study used data from the Dutch Youth Health Survey 2015.

Availability and implementation of guidelines in European child primary health care: how can we improve?

Background: Clinical guidelines are important for providing high-quality child primary health care. We aimed to assess the availability, use and achieved delivery of guidelines in the European Union (EU).

Methods: We used a case study design to ascertain expert views on guidelines in six countries representing the EU.

Physical Distancing and Social Media Use in Emerging Adults and Adults During the COVID-19 Pandemic: Large-scale Cross-sectional and Longitudinal Survey Study.

Background: Although emerging adults play a role in the spread of COVID-19, they are less likely to develop severe symptoms after infection. Emerging adults' relatively high use of social media as a source of information raises concerns regarding COVID-19-related behavioral compliance (ie, physical distancing) in this age group.

Objective: This study aimed to investigate physical distancing among emerging adults in comparison with adults and examine the role of using social media for COVID-19 news and information in this regard.

A Game-Based School Program for Mental Health Literacy and Stigma on Depression (Moving Stories): Cluster Randomized Controlled Trial.

Background: Depressive symptoms are highly prevalent among adolescents in Western countries. However, although treatment for depressive symptoms is available, many adolescents do not seek help when they need it. Important barriers to help-seeking among adolescents include low mental health literacy and high stigma.

White matter integrity in delinquent emerging adults and non-delinquent controls, and its relationship with aggression, psychopathic traits, and cannabis use.

Background: Atypical white matter integrity may be one of the biological factors related to delinquency. In adults, decreased white matter integrity has been related to antisocial behavior, but findings from research in adolescent and young adult populations are either mixed or lacking. Here we investigated this association within a naturalistic sample of delinquent young adults (age 18-27).

Testing a first online intervention to reduce conformity to cyber aggression in messaging apps.

Early adolescents frequently use mobile messaging apps to communicate with peers. The popularity of such messaging apps has a critical drawback because it increases conformity to cyber aggression. Cyber aggression includes aggressive peer behaviors such as nasty comments, nonconsensual image sharing, and social exclusion, to which adolescents subsequently conform.

Motivating Social Influencers to Engage in Health Behavior Interventions.

Social influencers are widely known as the promotors of purchase behavior as well as for their potential to change health behaviors among individuals in their social networks. For social influencers to be successful in changing behaviors, it is essential that they convey their message in an authentic, original, credible, and persistent manner. In the context of health behavior interventions, this requires a focus on the motivation of social influencers to engage in the intervention.

The association of early life stress with IQ-achievement discrepancy in children: A population-based study.

Early life stress (ELS) is associated with lower IQ and academic achievement; however, it remains unclear whether it additionally explains their discrepancy. In 2,401 children (54% girls, 30.2% migration background) from the population-based study Generation R Study, latent factors of prenatal and postnatal (age 0-10) ELS were estimated, and IQ-achievement discrepancy (age 12) was quantified as variance in academic achievement not explained by IQ.

Behaviour change interventions to promote health and well-being among older migrants: A systematic review.

Background: Whether behaviour change interventions are effective for the maintenance of older migrants' health and well-being is uncertain. A systematic review was conducted to assess evidence for the capacity of behaviour change techniques (BCTs) to promote the health and well-being of older migrants.

Methods: Electronic databases (Cochrane CENTRAL, Embase, Ovid MEDLINE and Web of Science) were searched systematically to identify relevant randomised controlled trials, pre-post studies and quasi-experimental studies published before March 2021.

The Roles of Social Media Use and Friendship Quality in Adolescents' Internalizing Problems and Well-being.

Adolescents spend increasing amounts of time using social media, but whether social media use has a beneficial or harmful role in internalizing problems and well-being during adolescence remains under debate. The present study explored associations of social media use and friendship quality with adolescents' internalizing problems and well-being both concurrently and longitudinally, including the exploration of interactive effects between social media use and friendship quality and the examination of gender differences. Online questionnaire data collected in Spring 2018 and Spring 2019 from 1,298 Dutch adolescents aged 11-17 years (mean age 13.

Suggested false memories of a non-existent film: forensically relevant individual differences in the paradigm.

There is ample evidence to suggest that posing leading questions is dangerous, in that it may elicit compliant responses that are not necessarily accurate. Further, suggestive questioning is considered to possibly result in the development of false memories, implied in the suggestion. [Crombag, H.

Development of social feedback processing and responses in childhood: an fMRI test-replication design in two age cohorts.

This study investigated behavioral and neural correlates underlying social feedback processing and subsequent aggressive behaviors in childhood in two age cohorts (test sample: n = 509/n = 385 and replication sample: n = 354/n = 195, 7-9 years old). Using a previously validated Social Network Aggression Task, we showed that negative social feedback resulted in most behavioral aggression, followed by less aggression after neutral and least aggression after positive feedback. Receiving positive and negative social feedback was associated with increased activity in the insula, medial prefrontal cortex and ventrolateral prefrontal cortex.

Burnout and Its Antecedents: Considering Both Work and Household Time Claims, and Flexibility in Relation to Burnout.

This study contributes to the previous literature by examining how flexible work arrangements interact with work and family time claims to affect burnout. It does so by providing a theoretical framework and empirical test of the interaction of flexibility with the effect of work and family time claims on burnout. Hypotheses and predictions based on previous literature are tested by Ordinary Least Squared regression models using data from the Time Competition Survey, constituting a sample of 1,058 employees of 89 function groups within 30 organizations.

Risk Factors For Hearing Decline From Childhood To Early Adolescence.

Objective: To identify risk factors of hearing decline between 9 and 13 years of age. The risk factors examined included sociodemographic, health, and lifestyle-related factors.

Methods: This study was embedded within a population-based prospective cohort study from fetal life onwards in the Netherlands.

Social media, parenting, and well-being.

One of the key challenges faced by many parents is to manage the pervasiveness of social media in adolescents' lives and its effects on adolescents' well-being (e.g., life satisfaction) and ill-being (e.

The Grow It! app-longitudinal changes in adolescent well-being during the COVID-19 pandemic: a proof-of-concept study.

Daily prosocial actions during the COVID-19 pandemic contribute to giving behavior in adolescence.

Prosocial actions are a building block for developing mature and caring social relations. However, the global pandemic may hamper adolescents' prosocial actions. In this preregistered study, we examined the extent to which adolescents provided daily emotional support during the COVID-19 pandemic.

Responsivity of the Striatal Dopamine System to Methylphenidate-A Within-Subject I-123-β-CIT-SPECT Study in Male Children and Adolescents With Attention-Deficit/Hyperactivity Disorder.

Background: Methylphenidate (MPH) is the first-line pharmacological treatment of attention-deficit/hyperactivity disorder (ADHD). MPH binds to the dopamine (DA) transporter (DAT), which has high density in the striatum. Assessments of the striatal dopamine transporter by single positron emission computed tomography (SPECT) in childhood and adolescent patients are rare but can provide insight on how the effects of MPH affect DAT availability.

Methods: As detailed in this study's pre-registration (osf.

Mechanisms linking physical activity with psychiatric symptoms across the lifespan: a protocol for a systematic review.

Introduction: Persistent psychiatric symptomatology during childhood and adolescence predicts vulnerability to experience mental illness in adulthood. Physical activity is well-known to provide mental health benefits across the lifespan. However, the underlying mechanisms linking physical activity and psychiatric symptoms remain underexplored.

Maternal preconception and pregnancy tobacco and cannabis use in relation to placental developmental markers: A population-based study.

Maternal tobacco and cannabis use during pregnancy are associated with adverse perinatal outcomes. We hypothesized that maternal tobacco and cannabis use are associated with placental adaptations, which subsequently lead to adverse perinatal outcomes. In a population-based prospective cohort study of 8008 pregnant women, we assessed maternal tobacco and cannabis use by questionnaires.

Exploring Parenting Profiles to Understand Who Benefits from the Incredible Years Parenting Program.

Behavioral parenting programs are a theory-driven and evidence-based approach for reducing disruptive child behavior. Although these programs are effective on average, they are not equally effective in all families. Decades of moderation research has yielded very few consistent moderators, and we therefore still have little knowledge of who benefits from these programs and little understanding why some families benefit more than others.
