Single-case synthesis tools II: Comparing overlap measures and parametric effect sizes for synthesizing antecedent sensory-based interventions

Varying methods for evaluating the outcomes of single case research designs (SCD) are currently used in reviews and meta-analyses of interventions. Quantitative effect size measures are often presented alongside visual analysis conclusions. Six …

Single-case synthesis tools I: Evaluating the quality and rigor of research on antecedent sensory-based interventions

Tools for evaluating the quality and rigor of single case research designs (SCD) are often used when conducting SCD syntheses. Preferred components include evaluations of design features related to the internal validity of SCD to obtain quality …

Using response ratios for meta-analyzing single-case designs with behavioral outcomes

Methods for meta-analyzing single-case designs (SCDs) are needed to inform evidence-based practice in clinical and school settings and to draw broader and more defensible generalizations in areas where SCDs comprise a large part of the research base. …

New paper: procedural sensitivities of effect size measures for SCDs

I’m very happy to share that my article “Procedural sensitivities of effect sizes for single-case designs with directly observed behavioral outcome measures” has been accepted at Psychological Methods. There’s no need to delay in reading it, since you can check out the pre-print and supporting materials.

Back from the IES PI meeting

I’m just back from the Institute of Education Sciences’ Principle Investigators conference in Washington D.C. It was an envigorating trip for me, and not only because of the opportunity to catch up with colleagues and friends from across the country.

Introduction to the special issue on single-case systematic reviews and meta-analysis

This special issue provides an update on recent conceptual and methodological developments for conducting systematic reviews and meta-analyses of single-case research. In this introductory article, we (a) describe the important role of systematic …

A meta-analysis of school-based group contingency interventions for students with challenging behavior: An update

Group contingencies are recognized as a potent intervention for addressing challenging student behavior in the classroom, with research reviews supporting the use of this intervention platform going back more than four decades. Over this time period, …

A meta-analysis of technology-aided instruction and intervention for students with ASD

The adoption of methods and strategies validated through rigorous, experimentally oriented research is a core professional value of special education. We conducted a systematic review and meta-analysis examining the experimental literature on …

New working paper: Using log response ratios for meta-analyzing SCDs with behavioral outcomes

One of the papers that came out of my dissertation work (Pustejovsky, 2015) introduced an effect size metric called the log response ratio (or LRR) for use in meta-analysis of single-case research—particularly for single-case studies that measure behavioral outcomes through systematic direct observation.

Functional assessment-based interventions for students with or at-risk for high incidence disabilities: Field-testing single-case synthesis methods

This systematic review investigated one systematic approach to designing, implementing, and evaluating functional assessment–based interventions (FABI) for use in supporting school-age students with or at-risk for high-incidence disabilities. We …
