Clinical Reasoning


The STEP-SI model is utilised by our Occupational therapists to support holistic service delivery. It was developed as a tool by Stackhouse, Trunnell and Wilbarger for facilitation of clinical reasoning between occupational therapists, parents and other health professionals.

The approach is divided into 6 dimensions for therapists to consider:

  1. Sensation

  2. Task

  3. Environment

  4. Predictability

  5. Self-monitoring

  6. Interactions

Our therapists utilise STEP-SI to provide scaffolding on multiple levels of the therapy process including: assessment, goal setting, direct intervention and home/community programs. As each client we see is unique, the STEP-SI enables our therapists to reason deeply for provision of individualised and effective therapy.
