- We need to ensure that intervention is delivered consistently within and across sessions.
- Without fidelity, we will not know what aspects, if any, of the intervention resulted in the change in behaviour (or lack thereof).
- A common approach is to develop a checklist to ensure that all key elements of the intervention are delivered according to plan. Examples include:
- Another person could assess the extent to which you deliver the intervention according to the plan.
- Record yourself delivering the intervention and complete the checklist while reviewing the recording.
- In the case of Jonathan, his parents could record one or more sessions and you could review recordings and assess for fidelity.
Think about and write down how you will measure the fidelity of your intervention. You may find it helpful to ask yourself the following questions:
- What are the key elements of the intervention?
- How often and where will it be delivered?
- How many opportunities will I create for my client to produce the target behaviour?
- What teaching strategies will I use and how often will I apply them?
- What will I do when the client produces the target behaviour?
- Who can assist in measuring the fidelity of the intervention?
