We aimed to screen children aged 18-48 months in the general population of nine Russian regions for risk of mental, behavioral and developmental disorders (MBDDs) including autism spectrum disorders (ASD) using an original screening tool. The prevalence of the risk for MBDDs is 1307:10,000 (13.07%), the prevalence of clinically verified cases of…

Over the past several decades, we have developed quality behavioral assessments and interventions for challenging behaviors among individuals with a variety of severe developmental and cognitive disorders. These assessments and interventions have been used to educate family members on how to understand and intervene with these behaviors at home…

Single-case designs substantiate the effectiveness of interventions for people with disabilities and other populations through the repeated measurement of behavior over time. Consequently, employing accurate and reliable systems of measurement is critical to the validity of single-case designs. Much of the data in single-case research are…

Objective: This study aims to delineate the characteristics of severe self-injurious behaviors (SIB) in a cohort of children with autism and unspecified intellectual developmental disorder (UIDD) (intellectual disability) and examine potential risk factors for developing SIB. Methods: A retrospective chart review studied characteristics of severe…

Truncating variants of the "MAGEL2" gene, one of the protein-coding genes within the Prader-Willi syndrome (PWS) critical region on chromosome 15q11, cause Schaaf-Yang syndrome (SYS)--a neurodevelopmental disorder that shares several clinical features with PWS. The current study sought to characterize the neurobehavioral phenotype of SYS…

Bullying and victimisation are extremely damaging behaviours that are present in schools all over the world. However, there is little research on the involvement of students with emotional and behavioural disabilities in the bullying dynamic and their risk and protective factors. Following the PRISMA guidelines, the search terms were entered in…

Background: The theoretical understanding of firesetting behaviour has predominantly been developed with men in prisons or psychiatric hospitals without neurodevelopmental disabilities. Consequently, there is a lack of evidence regarding the validity of current theory when applied to adults with intellectual disabilities and/or autism. Method:…

The transition from high school to adulthood is challenging for many students, but particularly for students who hold membership in marginalized populations. College and career readiness (CCR) supports can help students with intellectual and developmental disabilities (IDD) and emotional and behavioral disorders (EBD) and those who have had…

This study compared maternal responsiveness to children with two neurodevelopmental disorders sharing different but, in some cases, overlapping social phenotypes--Williams syndrome (WS) and autism spectrum disorder (ASD)--and explored the relations between maternal responsiveness and child emotional/behavioural problems (EBP). The sample included…

Introduction: Although the Aberrant Behavior Checklist (ABC) is one of the most widely used behavioral rating scales among people with developmental disabilities, very few studies have examined the factor structure of the non-English versions. Methods: The construct validity of the Norwegian ABC was examined in a clinical sample of children and…

Introduction: Research investigating the treatment outcomes of forensic intellectual and developmental disability (FIDD) services has largely focused on the perspectives of clinicians and researchers. This study sought the perspectives of patients and family/carers on the outcomes important to them. Methods: Semi-structured consultation groups…

The prevalence of refractive error and ocular disorders among infants and young children with severe behavioral problems and developmental disorders is not well defined, particularly in developing countries. We performed a retrospective review of ophthalmic examinations performed during a National Institutes of Health--funded cohort study of very…

Functional assessment and functional analysis are processes that have been applied successfully in work with people who have developmental disabilities, but they have been used rarely with students who experience emotional or behavioral disorders. In the present study, five students in elementary school programs for severe emotional disturbance…

The Good Behavior Game (GBG) is a classroom management system that employs an interdependent group contingency, whereby students work as a team to win the game. Although previous anecdotal data have suggested that this arrangement may promote prosocial behavior, teachers may have concerns about its fairness and potential to evoke negative peer…

Pica is a potentially deadly form of self-injurious behavior most frequently exhibited by individuals with developmental and intellectual disabilities. Research indicates that pica can be decreased with behavioral interventions; however, the existing literature reflects treatment effects for small samples (n = 1-4) and the overall success of such…
