The Systems Theory Framework (STF) facilitates the inclusion of relevant aspects of multiple existing theories within an integrated framework, wherein relevance and meaning is decided upon by each individual. Patton and McMahon emphasise that the application of the Systems Theory Framework in integrating theory and practice is located within the crucible of the individual, acknowledging that the individual is an open system recursively interacting with and within multiple systems. The present paper furthers a discussion of the potential for the Systems Theory Framework in theory integration, in particular with respect to relational theories.
