This study aimed at analyzing the differences in challenging behaviors between adults with intellectual disability and ASD and those who only had intellectual disability, as well as to explore associations between transdiagnostic and clinical variables to these differences. Therapists and educators of 163 adults with intellectual disability (83…

Prevalence studies of challenging behaviors among children with disabilities have a potential value, as they provide information for intervention and evaluation. However, the results from these studies seem to vary according to the population involved, the behaviors explored and the selected methodological procedures and instruments used. The…

Introduction: Challenging behaviors are common in individuals with developmental disabilities and pose significant challenges to their well-being and that of their families and communities. Method: We explored the occurrence and predictors of self-injurious behavior and aggressive/destructive behavior in 372 Canadian youths (aged 4-20 years) with…

Background: The aim was to investigate the aggressive behavior of young people in specialized institutions with intellectual disability (ID) with or without autism spectrum disorder (ASD). Method: Data on 305 institutionalized young people were collected using two aggression scales, the 'Children's Scale of Hostility and Aggression:…

Although there has been considerable research on the distinction between categories of relational and physical aggression, very little is known about the difference in nature of these behaviours. This study presented early childhood educators (N = 123) and parents (N = 112) with common relationally and physically aggressive behaviours, to…

Research has identified at least three patterns of direct involvement in bullying and victimization: bullying, bullying-victimized, and predominantly victimized. However, little is known about risk and protective factors for these patterns. As such, the goals of the present study were to establish these patterns and examine risk and protective…

The purpose of the study was to assess early literacy skills and examine the presence and stability of challenging behaviors across the critical threshold of the kindergarten school year. Students' (n = 337) literacy performance (letter sound fluency, word attack, and phonological awareness) and challenging behaviors (teacher ratings of…

Previous research is not conclusive in detailing the prevalence of challenging behaviour and its correlates in children with intellectual disabilities in school settings in particular. In the current study, an amended version of the Behaviour Problems Inventory -- Short Form was used to collect data from a sample of 321 students in a special…

Restraint and seclusion are crisis or emergency responses, which should only be used in extreme situations (e.g., a student engaging in repeated forceful physical aggression toward self or others) when risk of serious and imminent physical harm or injury is high and when an emergency response may reduce that risk. Restraint and seclusion are not…

In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically…

Internet trolling has been found to be a source of frustration and problematic for social media site users. Given that there have been few, if any, research studies examining the incidence and behavior of business undergraduates, the social media users and leaders of the future, this study was conducted. Findings suggest that students are active…

The purpose of the study was to assess early literacy skills and examine the presence and stability of challenging behaviors across the critical threshold of the kindergarten school year. Students' (n = 337) literacy performance (letter sound fluency, word attack, and phonological awareness) and challenging behaviors (teacher ratings of…

Verbal aggression (VA) is among the most prevalent forms of problem behavior in schools with detrimental effects for both perpetrators and victims, yet little is known about VA among students with emotional and behavioral disorders (EBD). Accordingly, we surveyed 279 teachers of students with behavioral disorders to examine the prevalence,…

Children with autism spectrum disorder (ASD) are at high risk for sleep disturbance and behavioral dysregulation. However, the relationships between these difficulties are not fully understood. The current study examined the relationships between specific types of sleep and behavioral problems among 81 children with ASD. Sleep problems were…

We report here the type of problems and solutions that 38 school teams reported during a randomized wait-list controlled trial of one problem-solving approach (Team Initiated Problem Solving [TIPS]). The experimental results from that analysis are reported elsewhere. The purpose of this article is to summarize companion descriptive data from this…
