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…

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 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…

This response to four commentaries (EC 608 302-305) on these authors' earlier paper discussing behavioral research methodology used with individuals with developmental disabilities (EC 608 301) contends that the original paper does not denigrate behaviorism and that practice needs to be informed by a variety of inputs regarding treatment decisions…

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…

This meta-analysis of the developmental disabilities literature on remediation of problem behaviors evaluated relations between standards of practice, intervention and participant characteristics, and treatment validity. Results largely failed to support widespread assumptions of clinical practice such as the superiority of more intrusive…

Maternal depression in families having a child with a disability has been the subject of considerable research over the past 25 years. This review was designed to describe the literature on maternal depression, critique its research methodology, identify consensus findings across studies, and make recommendations for future research. A particular…

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…
