Young children with developmental disabilities (DD) frequently have delays in social play skills. Students with DD may require social skills instruction in order to be successful in playing cooperatively with others. These opportunities to practice social play skills learned from specialized interventions must be available throughout the school…

The behaviors frequently displayed by students with autism can place them at risk for overly reactive behavior interventions with unwanted side effects. The current study examined the level of intrusiveness of behavioral treatments developed for 198 students with disabilities from 13 different states. Results demonstrated that students diagnosed…

The purpose of this study was to compare the effects of simultaneous prompting instruction with high and low treatment integrity on the learning of children with developmental disabilities. Low treatment integrity was defined as not delivering a controlling prompt during 30% of the teaching trials. Three preschool children with autism and…

A common recommendation for implementing time-out procedures is to include a release contingency such that the individual is not allowed to leave time-out until no problem behavior has occurred for a specific amount of time (e.g, 30 s). We compared a fixed duration time-out procedure to a release contingency time-out procedure with 4 young…

The present study was a multisite randomized clinical trial assessing the effects of adding a cognitive-behavioral intervention to positive behavior support (PBS). Fifty-four families who met the criteria of (a) having a child with a developmental disability, (b) whose child displayed serious challenging behavior (e.g., aggression, self-injury,…

This article reviews 43 U.S. studies assessing adaptive and challenging behavior outcomes associated with people with intellectual and developmental disabilities (IDD) who moved from institutions to community residential settings. These studies were published between 1977 and 2010. Longitudinal and comparison group studies were selected based on a…

The use of weighted vests for children with autism spectrum disorders and developmental disabilities is a common practice as part of sensory integration therapy programs. The purpose of the current investigation was to extend the research on the use of weighted vests for children with autism and developmental delays in a methodologically rigorous…

The present study examined whether Snoezelen and Stimulus Preference environments have differential effects on disruptive and pro-social behaviors in adults with profound mental retardation and autism. In N = 27 adults these target behaviors were recorded for a total of 20 sessions using both multi-sensory rooms. Three comparison groups were…

Methods and outcomes from functional behavioral assessment have been researched widely over the past twenty-five years. However, several important research questions have yet to be examined sufficiently. This quantitative review of developmental disability research aims to make comparisons of different functional behavioral assessment…

Individuals with autism spectrum disorders (ASD) are at increased risk for developing anxiety disorders relative to children without ASD and those with other developmental disabilities. Thirty-three children with high-functioning ASD and their parents participated in an original, manualized cognitive behavioral group treatment aimed at reducing…

This dissertation reviewed experimental studies centering on the Lovaas Method (LovM), reviewed experimental studies centering on Verbal Behavior Approach (VBA) and/or studies that focused on the primary verbal operants, and compared the effects of LovM and VBA on the development of tact repertoires of three 11 to 12-year-old students with…

This study evaluated two variants of a behavioral parent training program known as Stepping Stones Triple P (SSTP) using 74 preschool-aged children with developmental disabilities. Families were randomly allocated to an enhanced parent training intervention that combined parenting skills and care-giving coping skills (SSTP-E), standard parent…

This study tests the effectiveness of 2 approaches to parenting instruction for parents of preschool developmentally delayed children aged 3 through 5. Sixty parent/child pairs were randomly assigned to 1 of 3 groups: (1) individual parenting instruction only, (2) individual plus group instruction, and (3) comparison group with no instruction.…

There is growing evidence of an association between physical illness and problem behavior in children with developmental disabilities. Such behavior can compromise school performance. Therefore, the purpose of the present study was to evaluate, using a group design, the effectiveness of medical intervention alone (N = 11) versus behavioral plus…
