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…

In order to better assist practitioners and better serve persons with autism spectrum disorders (ASD) and their families, it is vital for professionals to systematically evaluate the existing body of literature and synthesize its scientific evidence, so that the efficacy of research can be translated to evidence-based practices (EBPs) (Wheeler,…

The purpose of this study was to assess the degree to which behavioral intervention studies conducted with persons with mental retardation operationally defined the independent variables and evaluated and reported measures of treatment integrity. The study expands the previous work in this area reported by Gresham, Gansle, and Noell (1993) and…

This meta-analysis investigated the efficacy of peer-mediated interventions for promoting social interactions among children from birth to eight years of age diagnosed with ASD. Forty-five single-subject design studies were analyzed and the effect sizes were calculated by the regression model developed by Allison and Gorman (1993). The overall…

Horner et al. (2005) present a review substantiating how single-subject research methodology can be utilized to determine whether interventions are evidence-based practices (EBPs). The current study utilized the Horner et al. research piece to: (a) systematically identify a set of quality standards for the evaluation of single-case research…

The prevalence of autism has increased approximately four times in children in nearly one decade (California Health and Human Services Agency, 2003). It has been reported that explanations such as immigration, shifts in the interpretation of diagnostic criteria, improved identification, or diagnostic accuracies cannot explain the observed increase…

Functional analysis was used to determine the possible function of inappropriate spitting behavior of an adult woman who had been diagnosed with profound mental retardation. Results of an initial descriptive assessment indicated a possible attention function and led to an attention-based intervention, which was deemed ineffective at reducing the…

The phenomenon of pica has been described within the literature in many ways, from a socially acceptable practice to a life threatening behavior. Recent prevalence rates of pica indicate relatively low occurrence of this phenomenon that makes it difficult to easily identify trends in practices related to pica. Recent literature on pica (1990 to…

A brief structural analysis of instructional variables assessed levels of task engagement and self-aggression behavior in a seven-year- old child with multiple disabilities. Results indicated increased levels of task-engagement and reduced levels of self-aggression as stepwise changes in treatment components occurred, validating use of structural…

Individualized activity schedules were successfully used with a 4- year-old child with autism who attended an integrated public pre-school classroom. Graduated physical guidance and a system of most-to-least prompts were used during skill acquisition stages with teacher proximity and level of prompts being eventually faded. (Contains nine…

Social skills training and self-monitoring were used to remediate socially inappropriate behaviors of a man with Down Syndrome in a supported competitive employment setting. Social behaviors of the moderately mentally retarded man were improved and maintained over a 38-week period, as trainer support was systematically faded over time. (Author/JDD)

This exploratory resource allocation model for implementing community-based supported employment services for persons with mental retardation uses a multivariate linear regression approach to project the hours required to develop a job site based on the size of the community, the rate of unemployment, and the percent of service jobs.

An assessment of the needs of persons with developmental disabilities and their families was conducted via focus groups of individuals with disabilities, family members, and professionals (n=50). Concerns included preservice staff training, inservice staff training, and program delivery and development. Implications for quality assurance and…
