Reading difficulties are linked to several disadvantages in the general population. Less is known about correlates of reading difficulties in individuals with intellectual and severe developmental disabilities (IDD). Vocabulary and word reading were assessed in 112 adolescents with IDD, recruited from Special needs comprehensive schools in Sweden…

Students with intellectual and developmental disabilities (IDD) require intensive supports, including those that target behavior, to make progress on literacy goals. In this study, we investigated whether computer-assisted instruction (CAI) may be one effective method to decrease challenging behavior and increase academic engagement. Participants…

Purpose: Research is only beginning to address the extent to which evidence-based parenting programmes have utility and merit within populations of children and families with neurodevelopmental disorders (NDD). The purpose of this paper is to evaluate a parent-focused intervention for families who have a child with a NDD and investigate whether…

Purpose: For over two decades, we have known that children with developmental language disorder (DLD) are underserved. We have also known that DLD does not attract the research attention that it merits given its prevalence and impact. The purposes of this clinical focus article are to present evidence that these failures continue, explore the…

Background: Language development has been characterised by significant individual stability from school entry. However, the extent to which trajectories of language growth vary in children with language disorder as a function of co-occurring developmental challenges is a question of theoretical import, with implications for service provision.…

This dissertation is composed of four stand-alone yet linked chapters. Chapter 1 provides an overview of the theoretical underpinnings of the constructs of adaptive behavior and support needs and their evolution throughout history. There is also a review of the limited literature available examining the relationship between the two constructs that…

Few studies have explored the subjective mental health of adolescents with intellectual disabilities, while proxy ratings indicate an overrepresentation of mental health problems. The present study reports on the design and an initial empirical evaluation of the Well-being in Special Education Questionnaire (WellSEQ). Questions, response scales,…

The transition to school may be particularly difficult for children with developmental disabilities and behavioral difficulties. Such children are likely to experience problems with self-regulation skills, which are critical to school adjustment. Additionally, inconsistent discipline practices and low parental involvement in children's schooling…

Severe behavior problems among people with intellectual and developmental disabilities (IDD) are a major barrier to integration in the community. Recent research suggests that these behaviors often begin very early in life and might be prevented by early identification and intervention (Rojahn, Schroeder, & Hoch, 2008). The current article…

Students' leaving a designated area without permission or supervision is referred to as "elopement," and such behavior clearly presents a unique set of challenges for educational professionals. Elopement is seen in children and youth with a variety of developmental disabilities, including those with intellectual disabilities or autism, as well as…

This article reviews 43 U.S. studies assessing adaptive and challenging behavior outcomes associated with people with intellectual and developmental disabilities (IDD) who moved from institutions to community residential settings. These studies were published between 1977 and 2010. Longitudinal and comparison group studies were selected based on a…

There is a very substantial literature over the past 50 years on the advantages of early detection and intervention on the cognitive, communicative, and social-emotional development of infants and toddlers at risk for developmental delay due to premature birth or social disadvantage. Most of these studies excluded children with severe delays or…

This cross-sectional study examined perceived access to services, quality of care, and family impact reported by caregivers of children aged 3-17 years with autism spectrum disorders, as compared to caregivers of children with other developmental disabilities and other mental health conditions. The 2009-2010 National Survey of Children with…

Researchers and clinicians are recognizing that a subgroup of children with Down syndrome (DS) also present with clinically significant impairments in social-communication and restricted patterns of behavior, such as those that characterize autism spectrum disorders (ASD). Efforts to better describe the behavioral presentation of children with…

The American Academy of Pediatrics recommends vision screening of all children between 3 and 5 years of age, and states have mandated vision screening for all school children. Participants were three 4-6-year old school children with either a developmental delay or autism who scored "could not test" on the state required vision screening.…
