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…

Physical activity has many benefits, but many individuals with developmental disabilities fail to exercise regularly. Procedures in which consequences were arranged for exercising, alone or as part of a treatment package, have consistently increased physical activity by members of this population. We review 19 studies that arranged such…

Research related to the developmental disability (DD) community should include collaboration "with" individuals with DD. Unfortunately, people with DD are infrequently involved in research projects in meaningful ways, and there is little guidance about how to collaborate equitably with researchers with DD. The purpose of this article is…

Single-case designs substantiate the effectiveness of interventions for people with disabilities and other populations through the repeated measurement of behavior over time. Consequently, employing accurate and reliable systems of measurement is critical to the validity of single-case designs. Much of the data in single-case research are…

Purpose: The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method: We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were…

Dyslexia is one of the most studied learning disorders. Despite this, its biological basis and main causes are still not fully understood. Electroencephalography (EEG) could be a powerful tool in identifying the underlying mechanisms, but knowledge of the EEG correlates of developmental dyslexia (DD) remains elusive. We aimed to systematically…

A nuanced understanding of disparities impacting racialized people with intellectual and developmental disabilities (IDD) requires scholars employ research methods that make visible the structural factors that influence outcomes. Following the work of Tukufu Zuberi and Eduardo Bonilla-Silva, we explore race-based methodological considerations for…

Purpose: The aim of this scoping review was to map the research literature published in English and in peer-reviewed journals related to the home literacy environment of children and youth aged 3-21 years with intellectual and developmental disabilities (IDD) who have significant support needs, including children with complex communication needs.…

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…

Students with intellectual and developmental disabilities (IDD) are likely to experience writing challenges that can negatively impact their overall academic, vocational, and social success. The goals of this study were to determine what writing interventions have been used with students with IDD, how their writing skills have been measured, the…

Children exposed to intimate partner violence (IPV) can experience negative social, emotional, behavioral, and academic outcomes. A growing body of research has examined the relationship between intellectual and developmental disabilities (IDD) and IPV exposure. We systematically reviewed the literature for research exploring this relationship and…

Children with intellectual and developmental disabilities (IDD) are often excluded from research that concerns them due to diverse ethical and methodological issues. This paper provides strategies for how to include children with IDD as active participants of research, an issue which to date has received little attention in the research methods…

Purpose: Although the 5 studies presented within this clinical forum include children who differ widely in locality, language learning profile, and age, all were motivated by a desire to improve the accuracy at which developmental language disorder is identified within linguistically diverse schools. The purpose of this prologue is to introduce…

Recently researchers have begun exploring the efficacy of interventions designed to improve text comprehension skills for students with developmental disabilities (DD). Text comprehension is essential for understanding academic content as students with disabilities make progress in the general education curriculum. This article focuses on single…

Purpose: Eye-gaze methods have the potential to advance the study of neurodevelopmental disorders. Despite their increasing use, challenges arise in using these methods with individuals with neurodevelopmental disorders and in reporting sufficient methodological detail such that the resulting research is replicable and interpretable. Method: This…
