I am glad to see that a discussion about an integrally informed social service practice has opened. While it is true that much work needs to be done to bring an integral approach to the education of social workers, it is not the only way to one can inform others of this approach.
I facilitate a program that credentials front line social workers in family support practice. The program is Family Development Credentialing (FDC). http://cas.umkc.edu/fdc/ The FDC curriculum was created at Cornell. Here in Missouri, the credentialing agency is the University of Missouri - Kansas City. The FDC curriculum provides several entry points to discuss an integrally informed approach.
I have the used the AQAL model to facilitate a quadrical (is that a word) understanding of the families social workers works with. A principle of family support is that one works with the goals of the family. AQAL provides a framework for assessing the resources available for achieving the goal, and it also informs the worker as to what practices might strengthen the family in each quadrant. It is truly a multipurpose tool.
There seems to be more that one way to get the job done. Creating a integral social work theory is important, but I am not waiting around for the development to take place. I am a practioner, and AQAL informs practice in the here and now. What do you think?
