The aim of this study was to identify the outcomes expected and assessed by those providing service dogs to children with developmental disabilities. Seventeen registered service dog providers were invited to complete a mixed methods online survey. Five providers, who prepared dogs to work with a wide range of conditions and behaviours, mainly…

This study investigated the influence of maternal and child variables on the maternal responsivity of 55 mothers with young children with fragile X syndrome. Data included video observations of mother-child interactions in four different contexts, standardized assessments with the children, and standardized questionnaires for the mothers. The…

Historically, people with intellectual and developmental disabilities (IDD) have experienced health disparities related to several factors including: a lack of access to high quality medical care, inadequate preparation of health care providers to meet their needs, the social determinants of health (e.g., poverty, race and gender), and the failure…

Children with 22q11.2 deletion syndrome exhibit high rates of social-behavioral problems, particularly in the internalizing domain, indicating an area in need of intervention. The current investigation was designed to obtain information regarding parent and teacher ratings of the social-emotional behavior of children with 22q11DS. Using the Child…

This methodological review draws attention to the challenges faced by intellectual and developmental disabilities researchers in the appropriate design and analysis of group comparison studies. We provide a brief overview of matching methodologies in the field, emphasizing group-matching designs used in behavioral research on cognition and…

This study examined the constructs underlying the Movement Assessment Battery for Children-2 (M-ABC-2), Bruninks-Oseretsky Test of Motor Proficiency (BOTMP) and Vineland Adaptive Behavior Scale-2 (VABS-2) using the framework of the International Classification of Functioning Disability and Health--Child Youth version (ICF-CY) and the diagnostic…

The study examined the effectiveness of Group Triple P, a Level 4 variant of the Triple P multilevel system of parenting support, with Chinese parents who had a preschool aged child with a developmental disability, using randomized controlled trial design. Participants (Intervention group: 42; Waitlist Control group: 39) completed measures on…

A dysfunction in predictive motor timing is put forward to underlie DCD-related motor problems. Predictive timing allows for the pre-selection of motor programmes (except "program" in computers) in order to decrease processing load and facilitate reactions. Using functional magnetic resonance imaging (fMRI), this study investigated the neural…

Historically people with significant disabilities were restricted to places such as adult activity centers, sheltered workshops, nursing homes, and institutions. Studies have shown the high school drop-out rate for this population is higher than those who are non-disabled. Policy makers concluded that these individuals needed to be better prepared…

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…

This study examined the effectiveness, generalization, and maintenance of a multi-element intervention consisting of brief direct instruction social skill lessons, a prompting procedure, and a fading procedure to promote social engagement in an integrated lunchroom and playground setting for three elementary age students with developmental…

Despite decades of advocacy, most students with developmental disabilities continue to spend the majority of the school day in self-contained special education classrooms. However, there is tremendous variability of educational placement across the United States. Identification of geographic trends that explain this variability could provide…

Researchers have evaluated active support in agencies for persons with developmental disabilities to increase staff assistance and service user engagement. A systematic review identified two studies in which researchers reported three experimental evaluations of active support. Only one experiment showed a clear functional relationship between…

Parents are often the first to recognize early signs of developmental challenges, launching the family into an unanticipated journey that sometimes resolves quickly but sometimes not. Development depends on nurturing relationships that provide the necessary experiences to allow the child to develop. Equally important are the relationships that…

Background: Individuals with Prader-Willi syndrome (PWS) have been shown to demonstrate a particular cognitive deficit in attention switching and high levels of preference for routine and temper outbursts. This study assesses whether a specific pathway between a cognitive deficit and behaviour via environmental interaction can exist in individuals…
