The employment rate among persons with autism spectrum disorder has been noted as unacceptably low. Employment-support services are increasingly linked to the potential for favorable job outcomes, yet little is known about employment-support practices and the outcome of these interventions. This mixed-methods study examined employment-support…

Young children with developmental delays, neurodevelopmental disorders, or other developmentally atypical presentations are increasingly referred to the mental health system of care because of symptoms that include prolonged tantrums, aggression, anxiety, and sensory processing difficulties. Concerning behaviors can be viewed as constitutional…

Strategies for the early detection of autism spectrum disorders (ASD) in people with intellectual developmental disorder (IDD) are urgently needed, but few specific tools have been developed. The present study examines the psychometric properties of the EVTEA-DI, a Spanish adaptation of the PDD-MRS, in a large randomized sample of 979 adults with…

The United States has a long, complicated history with sex education as, often, different stakeholders advocate dissimilar educational frameworks (Irvine, 2004). Although controversies remain in defining the boundaries of sex education, there is a movement both nationally and internationally to define sex education comprehensively (Haberland &…

Mental illness, and its assessment and treatment, is a concern for caregivers and professionals working with people with intellectual disability (ID), as well as a cause of distress and disability for people with ID. Research in this area is hindered by difficulties associated with recognizing symptoms of mental illness and tracking their changes.…

The purpose of the analyses described in this report was to evaluate both the effects of two contrasting approaches to parent-provided child learning opportunities and the direct and indirect effects on both proximal and distal parent social-affective behavior and verbal appraisals. The participants were 71 children with significant developmental…

Transition from high school to adulthood for students with developmental disabilities is a monumental stage for both the individual and his or her family. Past research has shown that one of the most salient predictors of students' successful transition is their parents' involvement with transition planning, however, during this time parent…

In the past decade, American and Canadian pediatric societies have recommended that pediatric care clinicians follow a schedule of routine surveillance and screening for young children to detect conditions such as developmental delay, speech and language delays and disorders, and autism spectrum disorder. The goal of these recommendations is to…

The present study sought to determine if systematically teaching the use of visual supports to three students identified as having moderate to severe disabilities resulted in improved task completion and independence in general education settings. For each participant, a visual support system delineated a multi-step task, which prior to the…

Although solving word problems involves both literacy and mathematics skills, research to date has only targeted mathematical learning. This study sought to increase teaching efficiency by embedding literacy instruction within mathematical word problem solving instruction for three elementary students with intellectual and developmental…

A set of schools located across the United States partnered with a federally funded inclusive schools systems approach to improving outcomes for "all" students--both general and special education students, including students with extensive support needs stemming from intellectual and developmental disabilities. Two years of data from the…

There are concerns about the quantity and quality of personnel in early childhood intervention (ECI) as the numbers of infants and young children with delays and disabilities grow in number, needs, and diversity. The Early Childhood Personnel Center (ECPC) was funded to provide technical assistance (TA) to state systems of ECI and institutions of…

Purpose: We asked whether sentence repetition accuracy could be explained by interactions of participant processing limitations with the structures of the sentences. We also tested a prediction of the procedural deficit hypothesis (Ullman & Pierpont, 2005) that adjuncts are more difficult than arguments for individuals with developmental…

In working with individuals with intellectual and developmental disabilities (IDDs), it is direct care staff who are often required to collect data on individuals' behavior which is used as the basis for implementation of empirically based approaches for intervention and treatment. Due to limited resources, indirect and descriptive measures of…

Many postsecondary education programs for students with intellectual and developmental disabilities (IDD) provide support to these students by matching them with peer mentors. Though this practice is widely used, the scholarly literature offers little information about successful peer support models in higher education settings. To address this…
