The Systems Theory Framework (STF) is presented as an integrating and organising concept for the predominant theories of career. In order to test the integrative capacity of the STF, this research merges the STF's theoretical element of story with the Theory of Dialogical Self's model of personality. Implications for the practice of career counselling are discussed along with a working example of a career assessment procedure informed by the STF and the Theory of Dialogical Self. It is concluded that integration of the two theoretical bodies adds to the STF's explanatory capacity. There is further scope, however, for STF's integration with theories based upon varying epistemological and ontological assumptions.
