Behavioral pain assessment is possible for children and youth with intellectual and developmental disabilities (IDD). However, pain behavior is often misinterpreted as reflecting psychopathology. We examined whether psychopathology alters pain behavior. Caregivers of 123 children (56 girls ages 40 to 258 months) completed the Non-Communicating…

An archival study was conducted to document (a) types of challenging behavior, and (b) functional assessment outcomes, for a sample of persons with developmental disabilities who were referred to community-practicing behavior analysts for assessment and treatment of challenging behavior. Functional assessment reports, prepared by 17 behavior…

In Pacific Rim countries parents of children with developmental disabilities have organized peer support organizations. One form of peer support is Parent to Parent based on one to one connections between two parents. The movements to create and sustain peer support in the U.S., New Zealand, China, and Korea are described. Qualitative evidence…

Behavioral momentum theory provides a quantitative account of how reinforcers experienced within a discriminative stimulus context govern the persistence of behavior that occurs in that context. The theory suggests that all reinforcers obtained in the presence of a discriminative stimulus increase resistance to change, regardless of whether those…

Background: Intrusive interventions, once implemented, may remain in place longer than necessary unless their continued effectiveness is evaluated. Method: We conducted a phased timeout-evaluation for 34 individuals with developmental disabilities who received services from the same agency and whose treatment programmes contained timeout for…

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…

Translational research inspired by behavioral momentum theory in the area of developmental disabilities has shown effects in individuals over a range of functioning levels. In the current study, behavioral momentum was assessed in 6 children diagnosed with autism and severe intellectual disability. In a repeated measures design, participants were…

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.…

Sleep problems have often been reported in children with intellectual disabilities (ID). How anomalies in 24-h sleep patterns relate to behaviour difficulties in children with different types of ID remains to be elucidated. The purpose of this study was to assess 24-h sleep and behaviour patterns in children with a variety disorders including…

The aim of this project was to develop and validate a Service Needs Questionnaire (SNQ) on the service needs of families with children with developmental disabilities. The SNQ and a measure of parenting stress were administered to 105 parents of children diagnosed with learning/behaviour problems and 233 parents of children attending primary…

Functional analysis (FA) methodology is the most precise method for identifying variables that maintain problem behavior. Occasionally, however, results of an FA may be influenced by idiosyncratic sensitivity to aspects of the assessment conditions. For example, data from several studies suggest that inclusion of a tangible condition during an FA…

When responses function to produce the same reinforcer, a response class exists. Researchers have examined response classes in applied settings; however, the challenges associated with conducting applied research on response class development have recently necessitated the development of an analogue response class model. To date, little research…

Behavior analysis is a generic science, and Skinner's vision for it was that it would become a mainstream force, relevant for most if not all human concerns, major and minor. Clearly his vision has not been realized. Determining why this is the case would require a complex multifactorial analysis. One likely factor is that the majority of its…

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…

Children and adults with developmental disabilities are more likely to evince encopresis, soiling and constipation than the general population. This set of related behaviors can produce a great deal of stress and can be a major restriction in independent living. This paper provides a review of the current state of knowledge on the prevalence,…
