New article: Design-comparable effect sizes in multiple baseline designs: A general modeling framework

My article with Larry Hedges and Will Shadish, titled “Design-comparable effect sizes in multiple baseline designs: A general modeling framework” has been accepted at Journal of Educational and Behavioral Statistics.

Analyzing single-case designs: d, G, hierarchical models, Bayesian estimators, generalized additive models, and the hopes and fears of researchers about analyses

New approaches to the analyses of single-case designs are proliferating, which some single-case design researchers welcome and others view with skepticism. In this chapter we describe some of the analyses that we have been exploring, all of which can …

Analysis and meta-analysis of single-case designs with a standardized mean difference statistic: A primer and applications

This article presents a d-statistic for single-case designs that is in the same metric as the d-statistic used in between-subjects designs such as randomized experiments and offers some reasons why such a statistic would be useful in SCD research. …

A standardized mean difference effect size for multiple baseline designs

Single-case designs are a class of research methods for evaluating treatment effects by measuring outcomes repeatedly over time while systematically introducing different condition (e.g., treatment and control) to the same individual. The designs are …

A d-statistic for single-case designs that is equivalent to the usual between-groups d-statistics

We describe a standardised mean difference statistic (d) for single-case designs that is equivalent to the usual d in between-groups experiments. We show how it can be used to summarise treatment effects over cases within a study, to do power …

Operationally comparable effect sizes for meta-analysis of single-case research

This thesis studies quantitative methods for summarizing and synthesizing single-case studies, a class of research designs for evaluating the effects of interventions through repeated measurement of individuals. Despite long-standing interest in meta-analytic synthesis of single-case research, there remains a lack of consensus about appropriate methods, even about the most basic question of what effect size metrics are useful and appropriate.

A standardized mean difference effect size for single case designs

Single case designs are a set of research methods for evaluating treatment effects by assigning different treatments to the same individual and measuring outcomes over time and are used across fields such as behavior analysis, clinical psychology, …
