Using psychological network analysis, this study explored the heterogeneity of the network structure between extracurricular time-use and delinquency using a nationally representative longitudinal survey of at-school students in China (N = 10,279, 47.3% female, average age 13.6, 91.2% Han ethnicity). The results are threefold: First, time…

Objective: Problem-drinking among university students is common and poses serious health-related risks. Therefore, identifying and addressing associated factors is important. Participants and methods: A large cross-sectional online-survey with 12,914 university students from Berlin was conducted from November 2016 to August 2017. Relative-risk-…

Teachers experience learner challenging behaviour in primary schools worldwide. In South Africa, learner behaviour is undermining teaching and learning and compromising safety in some primary schools. To understand teachers' experiences of learner challenging behaviour, a qualitative data-collection approach was applied. Data from 15 teachers from…

The purpose of this study is to identify the prevalence and factors associated with weapon carrying in Colombian high-school students. A cross-sectional study was designed to analyze this phenomenon among students aged between 13 and 17 years. A sample of 1462 students participated, 18.46% of which reported having planned suicide, 56.16% reported…

Deviant behavior has become a daunting problem lately. More pupils are displaying abnormal behavior and thus destabilizing learning processes within school settings. It is a well-known fact that teenagers usually learn how to adapt to society and that aberrant behavior may lead to problems with conformity to societal values. Although the main…

Adolescence is a very complex period. Various teen problems haunt when they grow up to become adults. The same teenagers successfully face the challenges of their development so that they are free from a variety of risky behaviors. However, some of them also smoke, consume alcohol, have free sex, commit violence, and use drugs. This research is a…

The rapid growth of various types of addiction and deviance among children and adolescents has led to the necessity of psychological follow-up of children in the educational environment. Another high-priority task is to create a safe environment for childhood. The purpose of this article is to present the results of monitoring the state of work on…

Objectives: It has been suggested that students are healthier in schools where more students are committed to school. Previous research has examined this only using a proxy measure of value-added education (a measure of whether school-level attendance and attainment are higher than predicted by students' social profile), finding associations with…

This study investigated the social status (i.e., popularity, likeability, and friendships) of adolescents with an early onset of externalizing behavior (i.e., alcohol use, tobacco use, and antisocial behavior). Building on Moffitt's dual-taxonomy model, it was hypothesized that early onset adolescents were more popular, but not necessarily more…

Adolescence is the period between childhood and adulthood and the most important stage of a human being. Adolescence is a period of stress and storm. Students cannot adjust with their new-fangled role in life. They can have Emotional, Mental, Behavioural, and Adjustment problems known as "disorders". Behavioural patterns that appear in…

This paper analyzes the results of the study of prevalence of problem behaviour of students in primary and secondary schools. The starting point is that it is methodologically and logically justified to look for early forms of problem behaviour of students, because it is likely that adult convicted offenders at an early school age manifested forms…

Background: The study of gene-environment interactions (G by E) is one of the most promising strategies to uncover the origins of mental disorders. Replication of initial findings, however, is essential because there is a strong possibility of publication bias in the literature. In addition, there is a scarcity of research on the topic originated…

It is still under debate whether the reported effects of opioid maintenance therapy (OMT) on child behaviour are a direct effect of prenatal exposure, or whether other factors are involved. This prospective cohort study investigated three models: the teratogenic risk model, the maternal risk model, and a combined risk model in a group of 35…

This study examines whether the Communities That Care (CTC) prevention system influences targeted risk and protective factors and the subsequent development of problem behaviour among adolescents (12-18 years) in the Netherlands. In this quasi-experimental study of ten communities (five experimental, five control), adolescent outcomes were…

Research has documented that children and adolescents with attention-deficit/hyperactivity disorder (ADHD) are at increased risk of substance use problems. Few studies, however, have focused on early-onset substance use. This study therefore investigated how the two symptom dimensions of ADHD (hyperactivity/impulsivity and inattention) are…
