The current trend analysis was conducted to empirically document the characteristics of individuals with autism who participated in intervention research published between 1995 and 2009 in three journals ("Journal of Applied Behavior Analysis," "Journal of Autism and Developmental Disorders," and "Focus on Autism and Other…

The 20 most productive authors (in terms of number of articles authored) were identified across three major autism-specific journals ("Autism: An International Journal of Research and Practice, Focus on Autism and Other Developmental Disabilities," and the "Journal of Autism and Developmental Disorders") published between 1997…

This study examined factors associated with 9-month outcomes of 78 preschoolers with autism spectrum disorder ([ASD]; 66 males, mean age = 44.8 [7.0] months) receiving preschool special education services. Use of recommended intervention practices was observed in each student's primary educational setting: autism-only (n = 28), mixed-disability (n…

Social competence is an essential skill that can be promoted in inclusive high school classrooms. For high school students with developmental disabilities, peer-mediated interventions have shown promise for increasing social communication with feasible implementation. This study focused on increasing the appropriate peer interactions of three high…

Virtual manipulatives are increasingly being used to support students with autism spectrum disorder and intellectual and developmental disability (ASD/IDD), in mathematics. However, to date, virtual manipulatives have not been examined or classified as an evidence-based practice for students with ASD/IDD, despite classifications of virtual…

Inclusive education is now advocated as best practice in schools. However, the extent to which adolescents with severe disabilities access the abundant social and academic experiences available in general education classes remains uncertain. We conducted multiple observations of 146 U.S. high school students with severe disabilities (including…

Mathematics instruction for students with intellectual disabilities and autism is important. However, it is imperative for researchers and practitioners to focus on the maintenance of mathematical concepts and not just acquisition for these students. Through a single-case multiple probe across participants study, researchers explored an…

Joint attention, or shared attention to an object or event, is a pivotal skill for the development of social interactions and social communication. Joint attention typically develops in natural contexts within the first year of life. Children with autism spectrum disorder (ASD) and related developmental disabilities often experience difficulty…

Adults with autism spectrum disorder and intellectual disability often do not engage in healthy levels of physical activity despite its many benefits. We conducted a randomized control trial to evaluate the effectiveness and feasibility of the Step It Up program, which used supported self-management strategies, on daily step counts, health…

Although the impact of peer-mediated interventions on students with intellectual and developmental disabilities (IDD) has been studied extensively, little attention has focused on the peers without disabilities who are so central to these interventions. We reviewed 98 studies to examine the portrait of more than 3,000 peers without disabilities…

Classroom Pivotal Response Teaching (CPRT) is a community-partnered adaptation of a naturalistic developmental behavioral intervention identified as an evidence-based practice for autistic children. The current study evaluated student outcomes in a randomized, wait-list controlled implementation trial across classrooms. Participants included…

Students with intellectual and developmental disabilities (IDD) who attend inclusive postsecondary education (IPSE) programs gain many new and beneficial skills, including independent living, social, and employability skills. Another skill set that may be strengthened by attending an IPSE program is self-determination. There is limited research…

Use of evidence-based practices is important for the success of students in special education settings in public education. In total, 255 special educators in public education were surveyed about (a) use of instructional practices, (b) preparedness to use interventions, (c) access to training, (d) influences on decision-making, and (e) areas of…

Parents report that the process of getting an autism spectrum disorder (ASD) diagnosis is arduous, lengthy, and fraught with difficulties. This analysis of the Pathways survey data set examined the experiences of parents who said, at the time of the survey, that their child currently had ASD compared with parents who said, at the time of the…

The use of mobile devices has become a major medium of leisure engagement for the general population. However, individuals with intellectual disabilities (ID) experience disparities in technology access, which may limit their engagement in mobile device-based leisure. Little research has examined procedures for teaching individuals with ID to…
