Adapted Alternating Treatment Design: Methodological Study


At the recent Mid-South Regional Conference for Psychology in the Schools, Gini McClurg, pictured, presented on a study that examined a methodological issue with a specific single-subject research design.


The researchers explored methodological issues with the Alternating Treatment Design; specifically threats to internal validity. They determined that an adapted version would address the noted threats to internal validity by including a no-treatment phase.


Other results and implications are outlined in the linked poster. For other information about the study please contact either Gini McClurg ( or her faculty advisor, Dr. Chris Skinner ( or Dr. MariBeth Coleman (
