Previous studies have examined the relationship between sleep problems and challenging behaviors in school-aged children and adolescents with autism spectrum disorder (ASD). However, literature has not examined this relationship in the context of toddlers or, more specifically, toddlers with aggression. The present study was conducted to examine…

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…

This short-term longitudinal study examined how economically-impoverished children's moral reasoning predicts specific aggressive subtypes. Children (N = 106, M[subscript age] = 52.78 months, 51% boys, ethnically diverse backgrounds) from urban Head Start programs completed a structured story-interview pertaining to moral reasoning and judgement…

In this study, we identified the specific discipline decision situations (i.e., vulnerable decision points [VDPs]) that contribute most to racial discipline disparities from a sample of 2020 schools across the United States. We also examined how much VDPs contributed to overall discipline disparities and the extent which there was similarity among…

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…

To identify factors in adolescence that predict the onset of sexual violence in adolescence and young adulthood. Data were analyzed from six survey waves of the longitudinal Growing up with Media Study (2008-2018) conducted in the USA. Participants were 778 youth 13-18 years old at baseline, who completed online surveys assessing sexual violence…

Adolescent behavior now occurs offline and online. Frequently studied and treated independently, the relationship between offline problem behaviors and online risk taking is not well understood. This study asked whether there are any problematic behaviors predictive of online risk taking by high school students. Using a 2009 dataset of 2,077 high…

Introduction: Conduct problems are commonly reported among individuals with autism spectrum disorders (ASD) and children with other special health care needs (CSHCN). Environmental research indicates that exposure to natural environments can lead to decreased conduct problems; opposite effects (i.e., increased problems) are associated with built…

The current study evaluates the concurrent relationship between parent ratings of executive functioning and maladaptive behavior among children and adolescents with Down syndrome and then repeats this evaluation using teacher reports. Parents and teachers of 63 school-age children with Down syndrome rated the child's executive functioning…

Narcissistic youth use social media to engage in a variety of self-promotional behaviors, which have either antisocial or prosocial characteristics. Differing views exist to explain the processes underlying narcissistic self-promotion, either characterizing these actions as intentional, or as impulsive. This study compared intentional…

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…

Deficits in language skills are a risk factor for later aggressive behaviour. However, previous research has mainly addressed clinical or high-risk samples and relations between language and aggressive behaviour in preschoolers and children in primary school. Based on a German longitudinal project with N = 547 typically developing children, the…

In this study, we examined trajectories of specific domains of behavior problems (i.e., attention problems, depression/anxiety, and aggressive behavior) from age 6 to 18 in a sample of 55 children with fragile X syndrome. We also examined autism status and early parenting as predictors of subsequent behavioral trajectories. We found that attention…

Exposure to violence among children and adolescents has been linked to negative outcomes including posttraumatic stress disorder, externalizing problems, low academic achievement, and impaired social-emotional adjustment. Aggressive behaviors specifically are shown to be strongly predicted by both direct and indirect violence exposure. Aggressive…

The present study examined which aspects of the child's behavior and clinical profile accounted for three dimensions of parenting stress: related to parenting roles, to interactions with the child, and to the child. Measures of adaptive behavior, intellectual functioning, autism symptom severity, and challenging behavior and emotional difficulties…
