Quasi-experimental AB designs can rigorously assess progress when combined with effect size measures. This study found specific effect size measures offer adequate control over errors and sufficient power for AB design analysis.
Area of Science:
- Behavioral Science
- Research Methodology
- Applied Behavior Analysis
Background:
- Single-case experimental designs (SCEDs) often necessitate lengthy baselines or treatment withdrawal, posing practical and ethical challenges.
- Quasi-experimental AB designs present a viable alternative, but their validity requires further investigation.
Purpose of the Study:
- To evaluate the validity of nonoverlap measures of effect size for detecting changes in AB designs.
- To assess the reliability of AB designs in practical settings.
Main Methods:
- Utilized simulated data to analyze the performance of nonoverlap measures of effect size.
- Determined thresholds for three effect size measures to maintain a Type I error rate below 0.05.
- Examined the statistical power associated with these thresholds.
Main Results:
- Identified specific effect size measures that effectively control Type I error rates.
- Demonstrated that these measures provide sufficient statistical power for analyzing AB design data.
- Established thresholds for reliable detection of changes in AB designs.
Conclusions:
- Certain effect size measures are suitable for rigorous analysis of AB designs.
- Practitioners can confidently employ quasi-experimental AB designs with effect size measures to evaluate intervention effectiveness.
- This approach enhances the scientific rigor of applied practice.
