Background: Aggressive behaviour (AB) and non-suicidal self-injury (NSSI) are common in people with mild intellectual disability or borderline intellectual functioning, leading to adverse consequences for themselves and those around them. Method: We investigated the relationship between AB (both total and physical in particular) and NSSI and risk…

The present study aimed to investigate the impact of a hybrid pedagogical model consisting of Teaching Games for Understanding (TGFU) and Teaching for Personal and Social Responsibility (TPSR) on the impulsivity, antisocial behaviors, and cognitive function of adolescent students. The study involved 60 male adolescent school students with an…

The present study investigated prenatal and early postnatal risk factors associated with developmental patterns of disruptive behaviors (DBs; e.g., hyperactivity-impulsivity, noncompliance, physical aggression) from ages 1.5 to 5 years in a population birth cohort (N = 2,057; 50.7% boys). Six high-trajectory classes obtained by latent growth…

This study aimed to investigate the predictive effect of problematic behaviours on cognitive tempo and attention level of 60-66 months old children attending preschool education institutions. The research data were obtained from 155 children between 60 and 66 months old attending independent kindergartens affiliated to the Ministry of National…

Individuals with attention problems often exhibit more off-task behaviors and less engagement in classroom settings, and exercising has demonstrated positive effects in decreasing disruptive behaviors and increasing on-task behaviors. The purpose of this study was to examine the effects of physical activity on academic engaged time for individuals…

Externalizing behaviors in individuals with autism spectrum disorder (ASD) are often either reduced or elevated compared to healthy controls (HCs). This study investigated the moderating role of context in ASD by comparing 32 individuals with ASD to 40 HCs during a social and a non-social provocation task. Compared to HCs, individuals with ASD…

Adolescent marijuana use has become increasingly more problematic compared with the past; thus, understanding developmental processes that increase the liability of marijuana use is essential. Two developmental pathways to adolescent substance use have been proposed: an externalizing pathway that emphasizes the expression of aggressive and…

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-…

Children who exhibit inattention (IA) and hyperactivity-impulsivity (HI), symptoms often indicative of attention-deficit/hyperactivity disorder (ADHD), have notable social impairments. We investigated whether IA and HI are directly connected to peer difficulties or indirectly connected through their known association with other problem behaviors.…

To investigate the contribution made by autistic children's Challenging Behaviour (CB) to their parents' anxiety and depression, parents of 32 autistic boys and 32 autistic girls (aged 6 to 18 years) completed standardised instruments on their children's behaviour and their own anxiety and depression. Significant associations were found between…

With the research reported on here we sought to determine whether children with attention-deficit/hyperactivity disorder (ADHD) displayed more symptoms of oppositional defiant disorder (ODD), conduct disorder (CD) and anger, which are categorised as externalising disorders, when contrasted to the control group and, also, whether gender and age…

Objectives: Researchers examined associations between specific forms of emotion dysregulation and numerous behavioral manifestations of impulsivity (i.e., problematic alcohol use, drug use, risky sexual activity, binge eating, non-suicidal self-injury). Participants: Participants were 238 undergraduate students (69% female). Method: Emotion…

Background: Problem behaviours are common among people with intellectual disabilities (ID), but psychometrically evaluated instruments for assessing such behaviours are scarce. The present study evaluated the psychometric properties of the Neuropsychiatric Inventory--Intellectual Disability (NPI-ID). Method: We assessed 108 residents with…

The current study explored early adolescent child-level predictors (physical aggression, impulsivity, empathy) and contextual-level predictors (peer deviance, neighborhood dangerousness) of violent and nonviolent antisocial behavior (AB) in late adolescence. Additionally, we tested the moderating role of rejecting parenting on these associations…

Background: The impact of chronic stressors like the COVID-19 pandemic is likely to be magnified in adolescents with pre-existing mental health risk, such as attention-deficit/hyperactivity disorder (ADHD). This study examined changes in and predictors of adolescent mental health from before to during the COVID-19 pandemic in the Southeastern and…
