Further Development of Effect Size Estimators for Single-case Designs: Extensions to Trend and Diverse Outcome Metrics

After some analytical work to develop the new effect size measures, the research team will use simulation studies to investigate the performance of the measures under a range of conditions typically found in single-case designs. Through additional analytical work, the research team will ascertain the statistical properties of the effect size measures. The team will then conduct more simulation studies, which focus on evaluating the necessary attributes for single-case designs to be able to detect the effects. As these measures clear the testing phase, the research team will program them into their current SPSS software for computing the effect size estimates from the previous grant work. Other products of this grant will include conference presentations and peer-reviewed journal articles reporting on the methodological work and the application of it to single-case research.
