Two non-U.S. quasi-experimental studies reported Active Support training was associated with increased engagement in individuals with IDD, but no randomized controlled trials (RCTs) exist. We evaluated effects of Active Support training on staff assistance, and social and nonsocial engagement in 75 individuals with intellectual and developmental…

Individuals with Autism Spectrum Disorder (ASD) and/or intellectual and developmental disabilities (DD) often struggle with behavior management and emotion-regulation (ER). In this manuscript, we describe the results of a chart review examining a group treatment program designed to address ER deficits in youth with ASD and/or DD. The intensive…

In working with individuals with intellectual and developmental disabilities (IDDs), it is direct care staff who are often required to collect data on individuals' behavior which is used as the basis for implementation of empirically based approaches for intervention and treatment. Due to limited resources, indirect and descriptive measures of…

Providing effective behavioral supports to decrease challenging behavior and replace it with appropriate alternative skills is essential to meeting the needs of many individuals with intellectual and developmental disabilities (IDD). It is also necessary for fulfilling the requirements of Medicaid-funded individual support plans and is important…

The predominant models on the emergence and maintenance of stereotypy in individuals with developmental disabilities are based on operant and neurobiological interpretations of the behavior. Although the proponents of the two models maintain largely independent lines of research, operant and neurobiological interpretations of stereotypy are not…

Theory and evidence suggest the potential value of prodromal intervention for infants at risk of developing autism. We report an initial case series (n = 8) of a parent-mediated, video-aided and interaction-focused intervention with infant siblings of autistic probands, beginning at 8-10 months of age. We outline the theory and evidence base…

The Delis Rating of Executive Function (D-REF) is a set of rating scales designed to assess executive functions and their constituent sub-processes in children and adolescents between the ages of 5 and 18. More specifically, the D-REF is a supplemental assessment of children and adolescents demonstrating behavioral or cognitive difficulties often…

The aim of this study was to validate a questionnaire on academic competence behaviour for use with Chinese preschool children in Hong Kong. A parent version and a teacher version were developed and evaluated. The participants included 457 children (230 boys and 227 girls) aged four and five years old, their preschool teachers and their parents.…

Developmental disabilities such as intellectual disability and autism are often accompanied by special sets of behaviors which are major challenges for the person and those in their community. Among the most worrisome of these are compulsions, rituals and obsessions. Often these behaviors are left untreated; however, when intervention does occur…

Recent insight into the underlying molecular and cellular mechanisms of fragile X syndrome (FXS) has led to the proposal and development of new pharmaceutical treatment strategies, and the initiation of clinical trials aimed at correcting core symptoms of the developmental disorder. Consequently, there is an urgent and critical need for outcome…

Although the use of differential reinforcement has been recommended in previous investigations and in early intervention curriculum manuals, few studies have evaluated the best method for providing differential reinforcement to maximize independent responding. This paper reviews previous research on the effectiveness of differential reinforcement…

We conducted a systematic analysis of studies that involved the treatment of rumination and operant vomiting in individuals with developmental disabilities. A total of 21 studies involving a combined 32 participants were identified and analyzed in terms of (a) participant characteristics, (b) dependent variables, (c) intervention procedures, (d)…

We evaluated whether differences in treatment effectiveness or preference between languages emerged across Spanish and English during functional communication training (FCT) for young children with developmental disabilities exposed to Spanish and English in the home environment. Participants were 2 young children with developmental disabilities…

We evaluated the effects of three different methods of denying access to requested high-preference activities on escalating problem behavior. Functional analysis and response class hierarchy (RCH) assessment results indicated that 4 topographies of problem behaviors displayed by a 13-year-old boy with high-functioning autism constituted an RCH…

Parents of children with a developmental disability require tailored parenting support, as their families have special needs and are at risk of increased burden. The aim of this study was to evaluate the efficacy of the Stepping Stones Triple P seminars, a brief group intervention for parents of a child with a disability. There were two seminars…
