Implementation has been observed to be crucial to the successful introduction of clinical supervision. Despite its importance, there is limited literature which articulates principles or process to guide it. The first and second parts of this three-part paper present findings of a qualitative exploration of the implementation of clinical supervision in a rural mental health service. The findings were discussed in light of the Driscoll model of implementation. While this model provided a valuable tool to interpret some aspects of the findings, its focus was primarily on the preimplementation stage, particularly in terms of assessing the workplace culture and the recognition of the pushing and resisting forces in relation to clinical supervision. This paper presents a new model of implementation with interrelated and dynamic stages. The model was developed in a rural mental health service context. An overview of this research-based model is presented in this paper.
