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,…

Analogue functional analyses are a well-researched means of determining behavioral function in research and clinical contexts. However, conducting analogue functional analyses in school settings can be problematic and may lead to inconclusive results. The purpose of this study was to compare the results of a trial-based functional analysis with…

A three-tier intervention system was designed for use with parents with preschool children with developmental disabilities to modify parent-child interactions. A single-subject changing-conditions design was used to examine the utility of a three-tier intervention system in reducing negative parenting strategies, increasing positive parenting…

Some individuals with developmental disabilities and emotional disorders may engage in challenging behavior that can result in the use of aversive procedures and/or seclusion from typically developing peers. They may also engage in low levels of physical activity. One way to decrease challenging behaviors while increasing overall levels of…

We conducted a systematic replication of Cannella-Malone et al. by comparing the effects of video prompting to video modeling for teaching seven students with severe disabilities to do laundry and wash dishes. The video prompting and video modeling procedures were counterbalanced across tasks and participants and compared in an alternating…

The authors describe a choice-making intervention with two children who had developmental disabilities and demonstrated public disrobing in school settings. The children also urinated in their clothing, apparently to gain access to new and more preferred apparel. The intervention gave the children a choice to change into high-preference clothes at…

The purpose of this study was to replicate previous findings indicating a moderate association between teacher perceptions of behavior as measured by direct behavior ratings (DBRs) and systematic direct observation (SDO) conducted by an external observer. In this study, data regarding student on-task and disruptive behavior were collected via SDO…

Problem behavior is a major barrier to successful community integration for people with developmental disabilities. Recently, there has been increased interest in identifying contextual factors involving setting events and discriminative stimuli that impact the display of problem behavior. The authors previously developed the "Contextual…

A critical measure of intervention effectiveness is durability over time. Still, few studies have examined the long-term outcomes of support derived from a functional behavioral assessment as well as enablers and barriers that contribute to or impede successful outcomes. In the current study, a functional behavioral assessment was conducted with a…

Direct methods of functional assessment--through which information is gathered by observing environment--behavior relations--vary with the degree to which environmental events are manipulated. Unstructured (ABC) assessments involve observing the occurrence of problem behavior without altering environmental events in any way. At the other extreme,…

Relationship quality (rapport) between people with developmental disabilities and their caregivers has long been suggested as an important variable influencing the likelihood of problem behavior. However, to date, the association between rapport and problem behavior has not been systematically investigated. The authors evaluated a multimethod…

Staff development efforts are being designed to have a greater impact on the systems in which professionals work to increase the likelihood that individual positive behavior support (PBS) plans will be effective. Statewide efforts aimed at embedding PBS into developmental disability organizations and other agencies must include longitudinal…

Functional behavioral assessment (FBA) has been suggested for facilitating the development and effectiveness of behavior intervention plans. In this study, the researchers examined whether behavior intervention plans based on FBA information (function-based) were more effective than behavior intervention plans not based on FBA information…

The authors describe a behavioral intervention designed to reduce sleep problems without increasing disruption at bedtime or throughout the evening. Sleep restriction was used to reduce the bedtime and nighttime sleep problems of two children, a 4-year-old girl with autism and a 4-year-old girl with developmental delay. Sleep restriction involved…

In this article, the authors examine the contributions of a progressive form of postmodern social theory to raising substantive issues about the politics of knowledge or the factors that govern decision processes regarding the nature of evidence from research. They examine the basis for the reaction against postmodernism that has appeared in the…
