Applied behavioral pharmacology explores how drugs may influence problem behavior in persons with intellectual and developmental disability (IDD). A comprehensive review was conducted featuring single-case experimental designs in the domain of applied behavioral pharmacology to evaluate and report on study quality. Studies included in the review…

Requests for pathological demand avoidance diagnoses have increased over recent years but pathological demand avoidance remains a controversial issue. We undertook a systematic review of peer-reviewed studies of pathological demand avoidance, using standardised appraisal and synthesis methods, to assess how pathological demand avoidance is…

This synthesis paper summarizes research literature addressing challenging behaviours in children and youth with autism spectrum disorders and developmental disabilities in school settings. We conducted a comprehensive literature review to identify relevant peer-reviewed articles published between the years 2000 and 2011. The methodological…

A combination of behavioral and medication-based interventions has been the most effective form of treatment for reducing problem behavior in individuals with intellectual and developmental disabilities. Evaluating the 2 types of interventions in combination and separately may require that researchers adapt methods traditionally used to evaluate…

We conducted a systematic literature review of anger management in people with intellectual disabilities (ID). We identified 2 studies that used randomized controlled trials and 6 that used pretest-posttest nonequivalent control group designs. The mean between-group effect size was 1.52 for randomized controlled trials and 0.89 for the other…

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…

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…

Methods and outcomes from functional behavioral assessment have been researched widely over the past twenty-five years. However, several important research questions have yet to be examined sufficiently. This quantitative review of developmental disability research aims to make comparisons of different functional behavioral assessment…

Despite the potential impact nutrition may have on learning, there have been surprisingly few papers published directed towards the educational research community. In contrast, omega-3 supplementation studies are being frequently cited in the media, leading to parents asking for advice and guidance. The purpose of this article is to review the…

We reviewed studies involving the treatment of elopement in individuals with developmental disabilities. Systematic searches of three electronic databases, journals, and reference lists identified 10 studies meeting the inclusion criteria. These studies were evaluated in terms of: (a) participants, (b) procedures used to assess elopement, (c)…

A review of studies that used the Questionnaire on Resources and Stress with families rearing children with developmental disabilities identified three primary difficulties: (1) definitional problems: (2) multiple measures of the same construct that do not converge: and (3) failure to replicate. Solution strategies include separating demands,…

This paper explores the reasonableness of expecting conventional experimental methodologies and research reports on behavioral interventions for persons with developmental disabilities to both support the validity of promising practices and guide the efforts of practitioners to implement those practices. New directions for research and practice…

This commentary on EC 608 301 points out that devotion to the natural science canon of experimental proof in the area of generality testing requires proof procedures that are difficult, expensive, or impossible, but adopting a different canon of proof will not produce the desired certainty about the accuracy of the answer. (JDD)

A total of 179 intervention research studies published from 1988-92 on the remediation of challenging behavior of persons with developmental disabilities was reviewed for adherence to certain standards of practice. Results indicate meaningful improvements in the state of intervention literature. Areas of progress are noted and continuing deficits…

Employed a developmental context to discuss the problem of assessing both quantitative and qualitative deficits in the behavioral profiles of various diagnostic subcategories of developmentally disabled children. Methods of appropriate matching of control groups are suggested to help delineate specific and general deficits in subgroups of…
