"For social change, a model of communication is required that is cyclical, relational and leads to an outcome of mutual change rather than one-sided, individual change. In Section 1 of this report we provide a description of such a model. The model describes a dynamic, iterative process that starts with a “catalyst/stimulus” that can be external or internal to the community. This catalyst leads to dialogue within the community that when effective, leads to collective action and the resolution of a common problem. The catalyst in the model represents the particular trigger that initiates the community dialogue about a specific issue of concern or interest to the community. This catalyst is a missing piece in most of the literature about development communication, which often assumes that the community spontaneously initiates dialogue and action. The model describes Community Dialogue and Action as a sequential process or series of steps that can take place within the community, some of them simultaneously, and which lead to the solution of a common problem."
