Community Health Action Model: health promotion by the community.

The goal of the Community Health Action (CHA) model is to depict community health promotion processes in a manner that can be implemented by community members to achieve their collectively and collaboratively determined actions and outcomes to sustain or improve the health and well-being of their community; the community as a whole, for the benefit of all. The model is unique in its ability to merge the community development process with a compatible community assessment, planning, implementation, and evaluation framework. The CHA model supports community participation leading to community-engaged assessment and change. In this article, the CHA model is depicted, its genesis described, and its utility demonstrated.
