Force Field Analysis was created by Kurt Lewin in the 1940s. Lewin originally used it in his work as a social psychologist. Today, however, it is also used in business, for making and communicating go/no-go decisions.
Having used elements of this theory a lot when working with autistic learners, I find it to be a really effect way to add structure to the process of decision making that can otherwise be too open ended.
I have uploaded my most recent version of the worksheet activity.
