Students' leaving a designated area without permission or supervision is referred to as "elopement," and such behavior clearly presents a unique set of challenges for educational professionals. Elopement is seen in children and youth with a variety of developmental disabilities, including those with intellectual disabilities or autism, as well as…

Analogue functional analyses are widely used to identify the operant function of problem behavior in individuals with developmental disabilities. Because problem behavior often occurs across multiple settings (e.g., homes, schools, outpatient clinics), it is important to determine whether the results of functional analyses vary across settings.…

A review and extension of previous conceptualizations of treatment acceptability is provided in light of progress within the area of behavior treatment development and implementation. Factors including legislation, advances in research, and service delivery models are examined as to their relationship with a comprehensive conceptualization of…

We treated a child with intestinal failure who consumed solids on a spoon but not liquids from a cup. We used spoon-to-cup fading, which consisted of taping a spoon to a cup and then gradually moving the bowl of the spoon closer to the edge of the cup. Spoon-to-cup fading was effective for increasing consumption of liquids from a cup. (Contains 2…

The purpose of this study is to compare the effectiveness of consultation alone and consultation plus feedback on the proper use of positive behavior support strategies (PBS) on behaviors of three mothers with children with developmental disabilities. Results indicated that consultation plus feedback was more effective than consultation alone…

This study examined relationships between three factors related to teacher self-efficacy (use of inclusive instruction, collaboration with others, and managing disruptive behaviour) and practicing teachers' sentiments, attitudes, and concerns about inclusive education of students with developmental disabilities. We calculated Pearson…

We manipulated relative reinforcement for problem behavior and appropriate behavior using differential reinforcement of alternative behavior (DRA) without an extinction component. Seven children with developmental disabilities participated. We manipulated duration (Experiment 1), quality (Experiment 2), delay (Experiment 3), or a combination of…

Skin-picking is a type of self-injurious behavior involving the pulling, scratching, lancing, digging, or gouging of one's own body. It is associated with social impairment, and increased medical and mental health concerns. While there are several reports showing that skin-picking is common in individuals with developmental disabilities, knowledge…

This study aimed to examine the use of a predictive stimulus (Time Timer[TM]) and delayed reinforcement to increase appropriate waiting behavior in a child with developmental disabilities and problem behavior maintained by access to tangible items and activities. The study employed a changing criterion design across settings to gradually increase…

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…

We conducted a three-phase study to evaluate the use of mands and the occurrence of problem behavior for 2 children with developmental disabilities. During Phase 1, a functional analysis identified the variables maintaining problem behavior. During Phase 2, functional communication training was implemented within a concurrent schedules design. The…

We evaluated the feasibility and utility of a laboratory model for examining observer accuracy within the framework of signal-detection theory (SDT). Sixty-one individuals collected data on aggression while viewing videotaped segments of simulated teacher-child interactions. The purpose of Experiment 1 was to determine if brief feedback and…

For most children, the developmental stage of exploring the world by putting everything, food and non-food items, in or around the mouth begins at birth and ends around 18 months of age. However, for those with developmental disabilities, this tendency may last into adulthood with the ingestion of non-nutritive, non-food items, a disorder called…

Aggression can present as a significant problem behavior in individuals with a diagnosis of developmental disability. Much research has focused on the prevalence of aggression in individuals with varying degrees of severity of intellectual disability (AD), autism spectrum disorders (ASD) and co-morbidity of ID and ASD. Research has also focused on…

Picture Exchange Communication System (PECS) is a picture-based communication strategy used to teach communication skills to persons with developmental disabilities including autism. This article systematically reviews 13 published single-subject studies to examine the effectiveness of PECS, the effects of PECS on speech and problem behaviors,…
