Using methods that are more common in medicine and similar fields, Gretchen Scheibel, Thomas Zane, and Kathleen Zimmerman (2022) evaluated relative economic costs of two methods that will be familiar to readers who are concerned with autism: DIRFloortime and RPM (rapid-prompting method). Their purpose was not to compare the effectiveness of the methods (they drew on other literature to examine that question), but to assist policy makers, administrators, and others who make decisions about what intervention strategies to employ, based on the economic costs of those two strategies.

Scheibel and colleagues examined both the financial costs and the amount of time required to implement the strategies.
