This systematic review evaluates single-case research design studies investigating applied behavior analytic (ABA) interventions for people with Down syndrome (DS). One hundred twenty-five studies examining the efficacy of ABA interventions on increasing skills and/or decreasing challenging behaviors met inclusion criteria. The What Works…

The current study evaluates the concurrent relationship between parent ratings of executive functioning and maladaptive behavior among children and adolescents with Down syndrome and then repeats this evaluation using teacher reports. Parents and teachers of 63 school-age children with Down syndrome rated the child's executive functioning…

Children with autism spectrum disorder (ASD) require substantial support to address the core symptoms of ASD and co-occurring behavioral/developmental conditions. This study explores the early diagnostic experiences of school-aged children with ASD using survey data from a large probability-based national sample. Multivariate linear regressions…

Building the communicative competence of individuals who use augmentative and alternative communication (AAC) requires intervention and support. This systematic review examined experimental studies involving aided AAC modeling to promote the expressive communication of children and youth (i.e., birth to age 21) with complex communication needs.

Interventions that promote parent and child well-being in families with children with intellectual and developmental disabilities (IDD) are important, given the caregiving burden often associated with supporting children with developmental and behavioral challenges. This article summarizes a presentation made at the 2019 AAIDD annual conference…

This study evaluated the effects of a pyramidal training approach that used an expert trainer who taught teachers how to train their paraeducators. Three special education teachers were taught to train four paraeducators to provide students with intellectual and developmental disabilities opportunities to initiate (OTI). A multiple baseline design…

Supporting interaction in inclusive settings between students with complex communication needs (CCN) and their peers requires careful planning and support. We used a multiple-probe-across-participants design to investigate the efficacy of collaborative planning and peer support arrangements to increase peer interaction in inclusive classrooms.…

Children with intellectual and developmental disabilities (IDD) experience significant difficulties in attention, learning, executive functions, and behavioral regulation. Emerging evidence suggests that computerized cognitive training may remediate these impairments. In a double blind controlled trial, 76 children with IDD (4-11 years) were…

Individuals with autism have difficulty with social skills across the lifespan. Few social interventions have been examined for older individuals with autism who also have significant intellectual disabilities (ID). Previous research suggests that reciprocal imitation training (RIT) improves imitation and social engagement in young children with…

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…

A combination of behavioral and medication-based interventions has been the most effective form of treatment for reducing problem behavior in individuals with intellectual and developmental disabilities. Evaluating the 2 types of interventions in combination and separately may require that researchers adapt methods traditionally used to evaluate…

This study examines access to, utilization of, and quality of health care for Latino children with autism and other developmental disabilities. We analyze data from the National Survey of Children with Special Health Care Needs (N = 4,414 children with autism and other developmental disabilities). Compared with White children, Latino children with…

Parents and professionals typically report problem behavior as a significant concern for children with fragile X syndrome.
