Teaching Generalized Pretend Play and Related Behaviors to Young Children With Disabilities
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 related behaviors by four children with disabilities. Results indicated the teachers’ use of the intervention package was functionally related to increases in the children’s frequency and diversity of pretend play and related behaviors. Children also maintained responses in sessions without prompts and generalized across toys and contexts. The findings replicate previous studies on adult prompting of pretend play and extend the literature by assessing generalization of children’s pretend play across contexts and measuring intervention and implementation fidelity. Overall, this study provides a strong argument for engaging in systematic instruction of play, including pretend play, for children who do not display such behaviors.

Using Progressive Time Delay to Increase Levels of Peer Imitation During Sculpting Play
A multiple probe across participants with an embedded withdrawal single case research design was used to examine the effectiveness of a progressive time delay (PTD) procedure to teach preschoolers with disabilities to imitate their peers during a sculpting play activity. Data indicated the presence of a functional relation between the use of PTD and contingent reinforcement on increased levels of peer imitation across participants; levels also decreased when PTD was withdrawn, although not to baseline levels. Overall levels of peer imitation had a greater magnitude of change than demonstrated in previous research.

Evaluating Autism Diagnostic and Screening Tools for Cultural and Linguistic Responsiveness
While clear guidelines and best practices exist for the assessment of autism spectrum disorders (ASD), little information is available about assessing for ASD in culturally and linguistically diverse (CLD) populations. CLD populations might be misidentified and under-identified with ASD due to the assessment practices that we employ. Four autism diagnostic tools and six autism screeners were selected and evaluated for their cultural and linguistic responsiveness. Although the evaluation of ASD within CLD populations is highly complex, this study identified the need for improved autism assessment tools and practices. Without the appropriate assessment of these populations, CLD children will likely continue to be misidentified (or not identified at all) and will miss crucial intervention opportunities.

Parent-Implemented Interventions for Young Children With Disabilities
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, independent variables, measurement of implementation and intervention fidelity, parent training components, dependent variables, social validity, overall outcomes, and study rigor. The results indicated that, although all studies described parent training components, few reported implementation fidelity. Across the studies trainers were most likely to use performance-based feedback and modeling to support parent implementation of the intervention. Although 20 studies used single-case design methodologies, only 2 studies met contemporary single-case research design standards. The authors provide an analysis of implications for future research related to supporting high-fidelity implementation of parent-implemented interventions.

Increasing the Engagement and Complexity of Block Play in Young Children
Blocks and block play are ubiquitous to early childhood settings and as such provide a normative context for social interactions between children with and without disabilities. However, children with disabilities tend to engage in more repetitive and less complex play than their peers, which might limit social interactions and opportunities to practice skills across domains. The current study examined the use of imitation plus play expansions delivered in a small group instructional context on the engagement and complexity of block play in young children with or at-risk for disabilities and their peers. Results indicated that the target children increased levels of engagement with the intervention package. However, their levels of block play complexity increased only when visual and verbal prompts were added to the intervention package.

A Primer on Single-Case Research Designs: Contemporary Use and Analysis
The overarching purpose of this article is to provide an introduction to the use of rigorous single-case research designs (SCRDs) in special education and related fields. Authors first discuss basic design types and research questions that can be answered with SCRDs, examine threats to internal validity and potential ways to control for and detect common threats, and provide guidelines for selection of specific designs. Following, contemporary standards regarding rigor, measurement, description, and outcomes are presented. Then, authors discuss data analytic techniques, differentiating rigor, positive outcomes, functional relations, and magnitude of effects.

Teaching Object Play to Young Children With Disabilities: A Systematic Review of Methods and Rigor
In this systematic review, we examined the rigor and outcomes across 27 object play intervention studies using single-case research methodology. We focused on studies including children age 5 years or younger and examined several descriptive characteristics including materials, instructional packages, and settings. We also analyzed the facilitation and measurement of generalized play and several methodological features including quality, rigor, and visual analysis procedures. Overall, the identified studies demonstrated positive outcomes, although quality and rigor limited interpretations of the outcomes. Previous reviews also have noted strong outcomes and weak to moderate quality for single-case studies. Our results should be interpreted with caution given previous reviews of play intervention studies identified strong outcomes and quality from group-design studies. Additional replications testing robust interventions using single-case research with strong methodological rigor are warranted.

Comparison of Overlap Methods for Quantitatively Synthesizing Single-Subject Data
Four overlap methods for quantitatively synthesizing single-subject data were compared to visual analysts’ judgments. The overlap methods were percentage of nonoverlapping data, pairwise data overlap squared, percentage of data exceeding the median, and percentage of data exceeding a median trend. Visual analysts made judgments about 160 A-B data sets selected randomly from the Journal of Applied Behavior Analysis . The four overlap methods were compared for data sets in which all visual analysts agreed a change in data occurred or a change did not occur across conditions. Each overlap method had unacceptably high levels of errors. Given the findings and weaknesses of the overlap methods, their use should be abandoned. The desirable characteristics of a quantitative synthesis method are described.
