註釋 With the Singapore Government's initiation of regulating the alternative and complementary professions, the chiropractic profession in Singapore now has the opportunity to influence its own destiny through implementation of self-regulation. The purpose of this thesis is to investigate how a small professional group, exemplified by the members of the Chiropractic Association (Singapore) (TCAS), with a relevant outcome in mind, can lead to a redefinition of its role by using Participatory Action Research (PAR) to formulate self-regulation for the group. The central question addressed in this study is: How does a relatively small professional organisation, such as a chiropractic association, self-regulate in a changing health care environment?
