Attention-deficit hyperactivity disorder symptoms and bullying victimization from childhood to adolescence - A within-person cross-lagged approach.

Attention-deficit hyperactivity disorder (ADHD) and subclinical symptoms of hyperactivity-impulsivity and inattentiveness coincide with an increased risk of peer victimization. What remains unclear are the developmental dynamics of these associations. In a sample drawn from two Norwegian birth cohorts ( = 872; 49.

Containment Measures and Alcohol Consumption Among Drinking Higher Education Students Before and During the COVID-19 Pandemic: A Multilevel Analysis in 25 Countries.

Hazardous alcohol use tends to be more prominent among higher education students. The COVID-19 pandemic severely altered student life, raising questions on its impact on students' alcohol use patterns. The current study examined cross-country variations in drinking behaviors (weekly drinking and binge drinking), and the extent to which these variations were associated with containment measures implemented during the first wave of the COVID-19 pandemic.

Gaming motivation and well-being among Norwegian adult gamers: the role of gender and disability.

Introduction: Digital gaming is a popular and often social activity, also among adults. However, we need more knowledge of the social dynamics of gaming and its potential benefits for one's well-being. The current study aimed to examine gaming motivation, time spent gaming, and gaming performed together with friends, family, or romantic partner and how these aspects relate to expanded social network and well-being among men and women with and without disability.

Quantifying teenagers' sleep patterns and sex differences in social jetlag using at-home sleep monitoring.

Sleep plays an important role in the formative developmental processes occurring during the teenage years. At the same time, teenagers' changing bioregulatory mechanisms and psychosocial factors converge into the so-called social jetlag, a sleep timing misalignment between weekdays and weekends. The aim of this study was to quantify the course of day-to-day changes in sleep/wake patterns and sleep stage distributions, and the sex differences in social jetlag among teenagers.

Reciprocal Relations Between Conflicted Student-teacher Relationship and Children's Behavior Problems: Within-person Analyses from Norway and the USA.

Current evidence suggests that conflicted student-teacher relationships may increase behavior problems in children and vice-versa, but this may be due to confounding. We therefore analyzed their relation applying a within-person approach that adjusts for all time-invariant confounding effects, involving samples from Norway (n = 964, 50.9% females) and the USA (n = 1,150, 48.

Social withdrawal and academic achievement, intertwined over years? Bidirectional effects from primary to upper secondary school.

Background: Socially withdrawn children tend to perform poorer academically than their peers. What remains unknown, is the temporal ordering of the two phenomena. Also, substantial gender differences exist in both social withdrawal and academic achievement; thus, it is conceivable that the strength of the relation between them is gendered as well.

Sleep Characteristics in Esport Players and Associations With Game Performance: Residual Dynamic Structural Equation Modeling.

The current study aimed to examine sleep characteristics of esport players and the stipulated effects of game performance on consecutive sleep characteristics using residual dynamic structural equation modeling (RDSEM). A sample of 27 Counterstrike players with a mean age of 18½ years participated in the current study. Sleep was detected over a period of 56 days with a Somnofy sleep monitor that utilizes an impulse radio ultra-wideband puls radar and Dopler technology, and weekly game performance was reported by the players.

Trends in absolute and relative educational inequalities in health during times of labour market restructuring in coastal areas: The HUNT Study, Norway.

Background: Restructuring labour markets offers natural population-level experiments of great social epidemiological interest. Many coastal areas have endured substantial restructuring of their local labour markets following declines in small-scale fishing and transitions to new employment opportunities. It is unknown how educational inequalities in health have developed in formerly fishery-dependent communities during such restructuring.

Understanding coastal public health: Employment, behavioural and psychosocial factors associated with geographical inequalities. The HUNT study, Norway.

Recent decades have shown an international trend of decline in small-scale fishing; a longstanding and vital industry for numerous coastal populations. The decline has resulted in a loss of livelihoods in many coastal communities, potentially afflicting public health. Still, knowledge about the health situation of these areas is limited.

The co-occurrence between symptoms of internet gaming disorder and psychiatric disorders in childhood and adolescence: prospective relations or common causes?

Background: Internet gaming disorder (IGD) is highlighted as a condition for further study in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5). Some studies indicate that IGD appears comorbid with other psychiatric disorders. We examine concurrent and prospective links between symptoms of IGD and symptoms of common psychiatric disorders in childhood and adolescence to determine whether observed comorbidity is a result of (a) reciprocal relations or (b) common underlying causes.

Time Spent Gaming and Social Competence in Children: Reciprocal Effects Across Childhood.

Electronic games are popular and many children spend much time on this activity. Here we investigate whether the quantity of time children spend on gaming is related to their social development, making this the first study to examine this relationship in children. We examine prospective relations between time spent gaming and social competence in a community sample of Norwegian 6 year olds (n = 873) followed up at ages 8, 10, and 12, controlling for socioeconomic status, body mass index, and time spent gaming together with friends.

Screen time and the development of emotion understanding from age 4 to age 8: A community study.

Recent increase in children's screen activities has raised concerns that screen time may replace face-to-face interaction, and hence impair children's development of emotion understanding. This longitudinal community study of 960 Norwegian 4-year-olds, followed up at ages 6 and 8, examined bidirectional relations between screen use and emotion understanding. Results revealed that more screen time at age 4 predicted lower levels of emotion understanding at age 6.

Peer Rejection and Attention Deficit Hyperactivity Disorder Symptoms: Reciprocal Relations Through Ages 4, 6, and 8.

Attention deficit hyperactivity disorder (ADHD) predicts poor peer relationships. What remains unclear is whether poor peer relationships affect ADHD symptomatology. Hence, reciprocal effects of peer rejection and ADHD symptoms were examined in a community sample of 962 Norwegian children at ages 4, 6, and 8.

Reciprocal Relations Between Student-Teacher Relationship and Children's Behavioral Problems: Moderation by Child-Care Group Size.

In this Norwegian study, bidirectional relations between children's behavior problems and child-teacher conflict and closeness were examined, and the possibility of moderation of these associations by child-care group size was tested. Eight hundred and nineteen 4-year-old children were followed up in first grade. Results revealed reciprocal effects linking child-teacher conflict and behavior problems.

Preschool-age problem behavior and teacher-child conflict in school: direct and moderation effects by preschool organization.

The hypothesis was tested that the new open-group Norwegian day-care centers would more than traditionally organized centers negatively affect (a) current and (b) future teacher-child relationships, and (c) the developmental legacy of preschool problem behavior. The focus was on eight hundred and fifty 4-year-olds from 153 centers who were followed up in first grade. Results of this natural quasi-experiment revealed that children from open-group centers (a) experienced less teacher-child closeness in preschool and (b) more teacher-child conflict in first grade, and (c) that high levels of preschool problem behavior forecast especially high levels of future teacher-child conflict, but only for children from open-group centers.

Socioeconomic inequalities in mortality and repeated measurement of explanatory risk factors in a 25 years follow-up.

Background: Socioeconomic inequalities in mortality can be explained by different groups of risk factors. However, little is known whether repeated measurement of risk factors can provide better explanation of socioeconomic inequalities in health. Our study examines the extent to which relative educational and income inequalities in mortality might be explained by explanatory risk factors (behavioral, psychosocial, biomedical risk factors and employment) measured at two points in time, as compared to one measurement at baseline.

Preschool social exclusion, aggression, and cooperation: a longitudinal evaluation of the need-to-belong and the social-reconnection hypotheses.

The need-to-belong theory stipulates that social exclusion fosters aggression, whereas the social-reconnection hypothesis suggests that social exclusion promotes motivation to behave cooperatively. To date, empirical investigations of these contrasting views have focused on the immediate effects of social exclusion, yielding mixed results. Here we examine longer term effects of preschool social exclusion on children's functioning 2 years later.

Social exclusion predicts impaired self-regulation: a 2-year longitudinal panel study including the transition from preschool to school.

The need-to-belong theory stipulates that social exclusion (i.e., being rejected by peers) impairs the ability to self-regulate, and experimental studies with adults support this contention, at least on a short-term basis.

Income-related health inequalities in the Nordic countries: examining the role of education, occupational class, and age.

Numerous studies have concluded that people's socioeconomic position is related to mortality and morbidity, but that the strength of this association varies considerably both within and between European regions. This has spurred several researchers to more closely examine educational and occupational gradients in health in the Nordic countries to clarify the causes of cross-national differences. However, comparable studies using income as an indicator of socioeconomic position are still lacking.

Variations in relative health inequalities: are they a mathematical artefact?

Background: Substantial research has documented variations in the magnitude of relative socioeconomic differences in health across European countries, and within countries, across different age groups. The aim of this paper is to examine to what extent these variations are determined by differences in the overall rate or prevalence of a health outcome across countries and age-groups in the total population.

Methods: Three surveys (European Social Survey, and two different population census-mortality registry linked longitudinal data) were used.

Material, psychosocial, behavioural and biomedical factors in the explanation of relative socio-economic inequalities in mortality: evidence from the HUNT study.

Background: Previous studies have assessed the relative importance of material, psychosocial and behavioural factors in the explanation of relative socio-economic inequalities in mortality, but research into the contribution of biomedical factors has been limited. Our study examines the relative contribution of (i) material, (ii) psychosocial, (iii) behavioural and (iv) biomedical factors in the explanation of relative socio-economic (educational and income) inequalities in mortality.

Methods: Cohort study--baseline data from the Norwegian total county population-based HUNT 2 study linked to mortality data (1995/97 to 2003).

Effects of spouses' socioeconomic characteristics on mortality among men and women in a Norwegian longitudinal study.

A partner's socioeconomic characteristics can influence one's own health. Nevertheless, little is known about the relative importance of a partner's education, occupation and income in relation to inequalities in mortality. In this study, we consider the relative contribution of these three spouse characteristics to predicting general and cause-specific mortality in men and women.
