The Use of Single-Subject Research to Identify Evidence-Based Practice in Special Education:

Single-subject research plays an important role in the development of evidence-based practice in special education. The defining features of single-subject research are presented, the contributions of single-subject research for special education are reviewed, and a specific proposal is offered for using single-subject research to document evidence-based practice. This article allows readers to determine if a specific study is a credible example of single-subject research and if a specific practice or procedure has been validated as “evidence-based” via single-subject research.

Positive Behavior Support Evolution of an Applied Science

Positive behavior support (PBS) is an applied science that uses educational and systems change methods (environmental redesign) to enhance quality of life and minimize problem behavior. PBS initially evolved within the field of developmental disabilities and emerged from three major sources: applied behavior analysis, the normalization/inclusion movement, and person-centered values. Although elements of PBS can be found in other approaches, its uniqueness lies in the fact that it integrates the following critical features into a cohesive whole: comprehensive lifestyle change, a lifespan perspective, ecological validity, stakeholder participation, social validity, systems change and multicomponent intervention, emphasis on prevention, flexibility in scientific practices, and multiple theoretical perspectives. These characteristics are likely to produce future evolution of PBS with respect to assessment practices, intervention strategies, training, and extension to new populations. The approach reflects a more general trend in the social sciences and education away from pathology-based models to a new positive model that stresses personal competence and environmental integrity.

The motivation of self-injurious behavior: A review of some hypotheses.

The literature on self-injurious behavior suggests five major hypotheses concerning the motivation of such behavior: (a) self-injurious behavior is a learned operant, maintained by positive social reinforcement (positive reinforcement hypothesis); (b) self-injurious behavior is a learned operant, maintained by the termination of an aversive stimulus (negative reinforcement hypothesis) ; (c) self-injurious behavior is a means of providing sensory stimulation (self-stimulation hypothesis); (d) self-injurious behavior is the product of aberrant physiological processes (organic hypothesis); and (e) self-injurious behavior is an attempt to establish ego boundaries or to reduce guilt (psychodynamic hypotheses). Data bearing on each hypothesis are reviewed and evaluated. Effective treatment may depend on a recognition of the different motivational sources of self-injurious behavior and the developmental relationships existing among these sources. Animal analogue experiments may provide clues to the motivation of self-injurious behavior in cases in which human experimentation is ethically indefensible.

Evaluation, Diagnosis, and Treatment of Gastrointestinal Disorders in Individuals With ASDs: A Consensus Report

Autism spectrum disorders (ASDs) are common and clinically heterogeneous neurodevelopmental disorders. Gastrointestinal disorders and associated symptoms are commonly reported in individuals with ASDs, but key issues such as the prevalence and best treatment of these conditions are incompletely understood. A central difficulty in recognizing and characterizing gastrointestinal dysfunction with ASDs is the communication difficulties experienced by many affected individuals. A multidisciplinary panel reviewed the medical literature with the aim of generating evidence-based recommendations for diagnostic evaluation and management of gastrointestinal problems in this patient population. The panel concluded that evidence-based recommendations are not yet available. The consensus expert opinion of the panel was that individuals with ASDs deserve the same thoroughness and standard of care in the diagnostic workup and treatment of gastrointestinal concerns as should occur for patients without ASDs. Care providers should be aware that problem behavior in patients with ASDs may be the primary or sole symptom of the underlying medical condition, including some gastrointestinal disorders. For these patients, integration of behavioral and medical care may be most beneficial. Priorities for future research are identified to advance our understanding and management of gastrointestinal disorders in persons with ASDs.

Problem Behavior Interventions for Young Children with Autism: A Research Synthesis.

This paper provides a summary of research on behavioral interventions for children with autism 8 years of age or younger published between 1996 and 2000. The analysis is divided into four sections: (1) emerging themes in the technology of behavior support, (2) a review of existing research syntheses focusing on behavioral interventions, (3) a new literature review of current pertinent research, and (4) an evaluative discussion of the synthesis results and the fields future needs to develop effective behavioral interventions for young children with autism. The authors offer recommendations for strengthening the existing research base and advancing behavioral technology to meet the needs of the defined target population.

Toward a Technology of "Nonaversive" Behavioral Support.

Nonaversive behavior management is an approach to supporting people with undesirable behaviors that integrates technology and values. Although this approach has attracted numerous proponents, more adequate definition and empirical documentation are still needed. This article presents an introduction to the nonaversive approach. Important definitions are suggested, and three fundamental elements are presented: (a) an emerging set of procedures for supporting people with severe challenging behavior; (b) social validation criteria emphasizing personal dignity; and (c) a recommendation for prohibition or restriction of certain strategies. These elements are defined in hopes of stimulating further discussion and empirical analyses of positive behavioral support.

Behavioral Support for Students with Severe Disabilities Functional Assessment and Comprehensive Intervention

Behavioral support for students with severe disabilities has undergone dramatic advances in the past 15 years. The goals of effective behavioral support, as well as the procedures for reaching those goals, have broadened. Two central advances have been procedures for conducting functional assessment and the design of comprehensive interventions. The research foundation for these advances, implications for clinicians, and future research directions are presented.

Multiple effects of joint attention intervention for children with autism.

Joint attention refers to an early developing set of behaviors that plays a critical role in both social and language development and is specifically impaired in children with autism. In a series of three studies, preschool teachers demonstrated the effectiveness of discrete trial instruction and pivotal response training strategies to teach joint attention to 5 children with autism (Study 1). Parents of 2 of the 5 children also taught joint attention at home and in the community (Study 2). Several additional dependent measures demonstrated collateral improvements in expressive language and social-communicative characteristics that were socially validated by parent raters (Study 3). Results are discussed with respect to the importance of addressing different forms of joint attention, the necessity to extend intervention to naturalistic contexts and joint attention partners, the pivotal nature of joint attention, and whether intervention adequately addresses both the form and social function of joint attention.

Effects of Video Modeling Alone and with Self-Management on Compliment-Giving Behaviors of Children with High-Functioning ASD.

Children with high-functioning autism spectrum disorders (ASD) typically exhibit a lack of social reciprocity skills. They often struggle to maintain conversations, especially with topics of little or no interest to them, and to create meaningful relationships. By giving compliments to others, children with ASD have a means by which to show approval for issues of interest to others. Video modeling has been shown to be effective in teaching social behaviors, particularly when it is followed by additional practice, prompts, and role playing. This study, involving two experiments, focused on teaching compliment-giving responses and initiations through video modeling with embedded, explicit rules for giving compliments in the place of additional procedures following video viewing. A multiple-baseline design across participants revealed that video modeling with explicit rules served to produce and maintain compliments of the “response” type. Video modeling with the addition of contrived reinforcement contingencies served to produce compliment-giving initiations in the presence of a teacher who monitored the childrens behavior. The results of Experiment 2 showed that the inclusion of self-management strategies increased the childrens independence in the monitoring of their compliment-giving initiations. Experimental results pointed to the use of self-management as a means by which to produce social initiations when video modeling alone fails.

Promoting Social Interactions Between Students with Autism Spectrum Disorders and Their Peers in Inclusive School Settings

This study evaluated the impact of a peer training intervention on social interactions among three students with autism spectrum disorders (ASD) and their typical peers. Two second graders and one fourth grader with ASD participated. For each student with ASD, two to four typical peers participated in training sessions that targeted increased social interactions. Data collected during lunchtime and recess showed that the peer training intervention generally resulted in increased initiations by trained peers as well as increased initiations and responses by students with ASD. Unexpectedly, untrained peers also showed increased initiations. Future research directions are discussed, including characteristics of the peers selected for training (e.g., gender, popularity) and measurement of qualitative changes in social relationships and opportunities.
