This article presents the conceptual framework for a new method of classification of strategies of therapeutic intervention. The classification is based on the terms driving force and restraining force, where a driving force operates in the direction of achieving the therapeutic aim and a restraining force operates against this direction. Seven strategies are identified, and each is illustrated by an example from the literature. The seven strategies are (a) enhancing the driving forces, (b) reducing the restraining forces, (c) preventing the driving forces from reducing each other's effects, (d) preventing the restraining forces from enhancing each other's effects, (e) causing the driving forces to enhance each other's effects, (f) causing the restraining forces to reduce each other's effects, and (g) transforming the restraining forces into driving forces. The theoretical and practical value of the classification is discussed.
