Developed by Dr. Wolf Wolfensberger, the concept of model coherency is one of the themes of and for Social Role Valorization (SRV) theory. From the author:
- “The ideal service model–i.e., the one with the greatest model coherency–would be derived from the real, primary, and urgent needs of the people to be served, and all of its process components would match harmoniously with each other and the content so as to facilitate effective address of those needs. Thus, a very colloquial way of putting it is to say that: the right servers should be using the right materials, methods, and language, in the right settings, in order to do the right thing for the right recipients, who are grouped in the right way.” (Wolfensberger, A brief introduction to Social Role Valorization, 4th expanded edition, 2013, p. 144).
- “Human service models are combinations of assumptions, contents, and processes. Assumptions are the underlying premises, beliefs, and ideologies (whether conscious or unconscious) on which the model is based … Content refers to what the service model actually delivers, i.e., what does it convey to recipients … Process refers to the means by which the content is conveyed.” (Wolfensberger, A brief introduction to Social Role Valorization, 4th expanded edition, 2013, pp. 137-138).
