Although our field has made significant progress in the measurement of procedural fidelity in research studies, we argue for a more nuanced and expansive perspective on procedural fidelity. Specifically, we review the status quo of procedural fidelity measurement in intervention research along with specific suggestions for increasing both…

Withdrawal and multitreatment single subject research designs were used to evaluate the effectiveness of stay-play-talk (SPT) interventions on social behaviors of preschool-aged peers to children with disabilities. Each group included at least one socially competent peer and one child with Down syndrome who used an augmentative and alternative…

An antecedent exercise (AE) intervention was conducted with two young children who demonstrated challenging behaviors during a large group circle time activity in a preschool classroom; outcomes were evaluated in the context of alternating treatments designs. Results from the initial visual analysis suggested no overlap between conditions, with…

Low-income, minority families are underrepresented in the literature on parent training for school-aged children with autism spectrum disorder (ASD). Although the use of visual supports, such as visual schedules, is considered to be an evidence-based practice for children with ASD in school, it is not known whether this strategy is effective for…

Children with disabilities play less often and demonstrate fewer varied pretend play behaviors than children with typical development. A multiple-probe design was used to examine the relation between teachers' use of the system of least prompts and contingent imitation and the acquisition, maintenance, and generalization of pretend play and…

For children with complex communication needs (CCN), augmentative and alternative communication (AAC) devices offer a means to communicate and participate in daily activities. Effective implementation and intervention practices are needed for supporting teaching teams working with children with CCN to improve child use of AAC. The purpose of this…

Children with Down syndrome may be at increased risk of problems associated with inactivity. Early intervention to increase physical activity may lead to increased participation in typical activities and long-term increases in quality of life (e.g., decreased likelihood of obesity-related illness). A multi-component intervention, including video…

Although comparison studies are important in early intervention/early childhood special education (EI/ECSE), results of well-designed comparison studies are likely to be unpublished because of undifferentiated or differently differentiated results across participants. The purpose of this article is to highlight the utility of comparison designs in…

The purpose of this literature review was to analyze the research on parent-implemented functional assessment (FA)-based interventions for reducing children's challenging behaviors. Thirteen studies met the review inclusion criteria. These studies were analyzed across independent variables, types of parent coaching and support provided,…

Three studies are described that examined the relation between performance-based (PB) feedback delivered via e-mail and preschool teachers' use of recommended practices. The authors conducted the first two studies in the same classroom with different classroom staff. The third study was conducted with three different teachers employed in…

The purpose of this review was to analyze fidelity features in parent-implemented interventions for young children with disabilities. The authors conducted a review of 24 studies published in nine peer-reviewed journals. Each identified article was scored on the following categories: the participant characteristics, settings, study design,…
