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…

Each year, the Interagency Autism Coordinating Committee (IACC) releases a list of scientific advances that represent significant progress in the field. The "2020 Summary of Advances in Autism Research" provides short, plain language summaries of the top research breakthroughs selected by the IACC from a pool of research articles…

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…

Meta-analysis has become a popular tool to statistically integrate results across studies in order to formulate more general conclusions on treatment effectiveness. Unfortunately, traditional meta-analytic applications fail to answer the question whether enough cumulative knowledge is available to draw convincing statistical conclusions. Leaving…

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…

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…

Many children with mental retardation and developmental disabilities suffer from the consequences of chronic drooling. Behavioral treatment for drooling should be considered before other, more intrusive treatments such as medication and surgery are implemented. However, empirical studies on behavioral procedures are scarce. This article reviews 19…

The feeding behaviors of a child diagnosed with failure to thrive were assessed using descriptive analysis methodology to identify the schedules of reinforcement provided by the child's parents. This analysis revealed that the child's appropriate feeding behaviors (i.e., bite acceptance, self-feeding) were on a lean schedule of positive…

The paper reviews research on behavioral staff management strategies in institutions for developmentally disabled persons, considering procedural effectiveness of four approaches: antecedent, contingency management, self-control, and multifaceted interventions. Methodological problems in the research are noted, along with needs for research on…

This commentary on EC 608 302, which discusses behavioral research methodology involving individuals with developmental disabilities, argues that a clear distinction must be made between methods and models, there is a need for more broadly focused intervention studies considering the body of applied practical knowledge, and differences in research…

This commentary on EC 608 301, a paper on behavioral research methodology used with individuals with developmental disabilities, argues that the paper does not portray behavior analysis accurately, advances arguments that may not be reliably enough agreed upon, and seeks to modify reader behavior without sufficiently addressing the variables of…

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…
