We assessed potential factors associated with "current" or "ever" self-injurious behaviors, reported in the Autism Diagnostic Interview-Revised, among children with autism spectrum disorder (n = 692) from the Study to Explore Early Development. Data on factors examined were obtained from questionnaires, standardized clinical…

Promoting self-determination and choice opportunities for people with intellectual and developmental disabilities has become best practice in the field. This article reviews the research and development activities conducted by the authors over the past several decades and provides a synthesis of the knowledge in the field pertaining to efforts to…

This article provides a response to Romer and Walker from two distinct perspectives: the field of developmental disabilities and a parent of children with developmental disabilities. Jeffrey Strully describes his current role managing a moderate-sized agency in Los Angeles that provides individualized and personalized supports as well as his work…

Meaningfully synthesizing single case experimental data from intervention studies comprised of individuals with low incidence conditions and generating effect size estimates remains challenging. Seven effect size metrics were compared for single case design (SCD) data focused on teaching speech generating device use to individuals with…

The goal of the present study was to identify the positive character traits of staff working with a special education population and further understand how staff apply these traits in their work. Twenty-eight staff from a school/treatment program for students with autism and related developmental disorders completed the VIA Inventory of Strengths…

People who have intellectual and developmental disabilities (IDD) often rely on caregivers to assist in the medication management process. The aim of this study was to learn from caregivers, who are either family or support staff, what major issues arise throughout the process of managing medication and how these might be addressed. Problems…

Family educational involvement and parent--teacher relationships are important for supporting student outcomes and have unique implications for families of children with autism spectrum disorder (ASD). However, little research has examined child and family characteristics among families of children with ASD as predictors of family involvement and…

This manuscript provides a review of housing and independent living options for individuals with intellectual and developmental disabilities (I/DD). While there has certainly been an increased emphasis on community integration and inclusion for people with I/DD, barriers to delivering housing supports and services in natural, integrated settings…

Purpose: Identifying risk factors associated with neurodevelopmental disorders is an important line of research, as it will lead to earlier identification of children who could benefit from interventions that support optimal developmental outcomes. The primary goal of this review was to summarize research on risk factors associated with autism…

Although peer-mentoring relationships are critical to including youth with intellectual and developmental disabilities in postsecondary educational settings, little is known about the motivations and experiences of peer mentors. To investigate, we conducted a mixed-methods study in which 17 volunteer peer mentors completed the Volunteer Functions…

This article reports results of a 7-month qualitative study on intellectual and related developmental disabilities in Kinshasa, Democratic Republic of the Congo, particularly as they relate to the causes and meaning of intellectual and developmental disabilities (IDD). This study raises important questions related to the understanding of…

Through a secondary analysis of statewide data from Colorado, people with intellectual and related developmental disabilities (ID/DD) were classified into five clusters based on their support needs characteristics using cluster analysis techniques. Prior latent factor models of support needs in the field of ID/DD were examined to investigate the…

Developmental coordination disorder (DCD) affects 2-7 percent of school-age children and is characterized by low motor proficiency associated with poor balance, coordination and handwriting skills. Because of their motor difficulties, children with DCD suffer from anxiety, low self-esteem and are often less sociable than typically developing…

Although dyslexia runs in families, several putative risk factors that cannot be immediately identified as genetic predict reading disability. Published studies analyzed one or a few risk factors at a time, with relatively inconsistent results. To assess the contribution of several putative risk factors to the development of dyslexia, we conducted…

The Supports Intensity Scale-Children's Version (SIS-C)was developed to assess the support needs of children and youth aged 5 to 16 years with intellectual and developmental disabilities. Data from the standardization sample of the SIS-C were analyzed to evaluate the impact of the age cohorts (5-6, 7-8, 9-10, 11-12, 13-14, and 15-16 years) used to…
