Journal of Disability Policy Studies, 12(3), 177-197. http://dx.doi.org/10.1177/104420730101200304https://hdl.handle.net/1808/5929This article organizes and classifies the 18 core concepts. There are nine overarching principles into which the concepts fit: life, liberty, equality, dignity, family as foundation, community, capacity, individualization, and accountability. These in turn reflect three approaches to policy: the Constitutional approach, consisting of the principles of life, liberty, and equality; the Ethical approach, consisting of the principles of dignity, family as foundation, and community; and the administrative approach, consisting of the principles of capacity, individualization, and accountability. There is also a set of Professional principles, which the article illustrates with examples from the field of medicine/health care. Finally, the article demonstrates how the organization and classification of the core concepts create a wholistic, unified approach to policy.en-USArticle10.1177/104420730101200304openAccess
