How does the Intervention Wheel define 'advocacy'?

The Intervention Wheel defines advocacy as pleading someone's cause or acting on someone's behalf, while focusing on developing the capacity of the community, system, individual, or family to plead their own cause or act on their own behalf.

In the Intervention Wheel, advocacy is one of the public health interventions described at the practice level. Its defining purpose is twofold: to speak for or act for those who may not be able to do so, and more importantly, to build the capacity of the community, system, individual, or family to speak and act for themselves. This makes advocacy an empowering intervention rather than simply speaking on behalf of others.
