SFGT has found clinical application in the substance abuse treatment field, and appears to make conceptual sense as an application of competence-based principles to treatment. As such, it has the advantage of fitting the group therapy model common in most treatment agencies, thus not requiring extensive modification of the organization structures agencies use to deliver treatment. It also takes advantage of the unique curative factors of group therapy–factors that are of particular benefit to people struggling with substance abuse problems. The next step in the development of this approach is to conduct empirical tests of its usefulness. While there are conceptual reasons to think that it can be useful in treating people with substance abuse problems, there is, as yet, no empirical evidence that it is.
