single-case design

Multi-level meta-analysis of single-case experimental designs using robust variance estimation

Single-case experimental designs (SCEDs) are used to study the effects of interventions on the behavior of individual cases, by making comparisons between repeated measurements of an outcome under different conditions. In research areas where SCEDs …

Augmentative and Alternative Communication intervention targets for school-aged participants with ASD and ID: A single-case systematic review and meta-analysis

Objective: This meta-analysis reviews the literature on communication modes, communicative functions, and types of augmentative and alternative communication (AAC) interventions for school-age participants with autism spectrum disorders and/or …

Considering instructional contexts in AAC interventions for people with ASD and/or IDD experiencing complex communication needs: A single-case design meta-analysis

For children with autism or intellectual and developmental disabilities who also have complex communication needs, communication is a necessary skill set to increase independence and quality of life. Understanding the how, where, and communication …

Participant characteristics predicting communication outcomes in AAC implementation for individuals with ASD and IDD: Meta-analysis

This meta-analysis examined social communication outcomes in augmentative and alternative communication (AAC) interventions, or those that involved aided (e.g., speech generating devices, picture point systems) or unaided AAC (e.g., gestures, manual …

Between-case standardized mean differences: Flexible methods for single-case designs

Single-case designs (SCDs) are a class of research methods for evaluating the effects of academic and behavioral interventions in educational and clinical settings. Although visual analysis is typically the first and main method for primary analysis …

Single case design research in Special Education: Next generation standards and considerations

Single case design has a long history of use for assessing intervention effectiveness for children with disabilities. Although these designs have been widely employed for more than 50 years, recent years have been especially dynamic in terms of …

Examining the effects of social stories on challenging behavior and prosocial skills in young children: A systematic review and meta-analysis

Social stories are a commonly used intervention practice in early childhood special education. Recent systematic reviews have documented the evidence-base for social stories, but findings are mixed. We examined the efficacy of social stories for …

Systematic review and meta-analysis of stay-play-talk interventions for improving social behaviors of young children

Stay-play-talk (SPT) is a peer-mediated intervention which involves training peer implementers to stay in proximity to, play with, and talk to a focal child who has disabilities or lower social competence. This systematic review and meta-analysis …

The impact of response-guided designs on count outcomes in single-case experimental design baselines

In single-case experimental design (SCED) research, researchers often choose when to start treatment based on whether the baseline data collected so far are stable, using what is called a response-guided design. There is evidence that response-guided …

An examination of measurement procedures and characteristics of baseline outcome data in single-case research

There has been growing interest in using statistical methods to analyze data and estimate effect size indices from studies that use single-case designs (SCDs), as a complement to traditional visual inspection methods. The validity of a statistical …
