C.12 Select a measurement procedure to obtain presentative procedural integrity data that accounts for relevant dimensions

When evaluating the effectiveness of interventions, it’s essential to measure not only the outcomes but also how well the intervention is being implemented. This is where procedural integrity comes in. Here’s what you need to know about selecting measurement procedures to ensure interventions are accurate, appropriately dosed, and account for environmental constraints.

🔑Key Terms🔑

• Procedural Integrity (Fidelity): The extent to which an intervention is implemented as planned. This ensures that the steps in the intervention are followed correctly, increasing the likelihood of success.

• Accuracy: How closely the recorded data reflects what truly occurred.

• Dosage: The amount of time or frequency a treatment is delivered to a client.

How to Measure Procedural Integrity

1. Use a Task Analysis: Break down the intervention into specific steps. Create a checklist or data sheet to record whether each step is followed correctly.

   Example: For teaching a child to tie their shoes, the checklist might include steps like "Place one lace over the other" or "Create a loop with one lace."

2. Track Accuracy: Observed data should match what truly happened.

   Example: If a child engages in six instances of a behavior, the observer’s data should reflect that same number.

3. Measure Dosage: The frequency, intensity, or duration of the intervention.

   Example: If a child is prescribed six hours of therapy per week, ensure they receive the full time allocated.

Addressing Environmental Constraints

It’s not always possible to observe every step of every intervention. Supervisors must prioritize what to measure based on the context and individual needs.

• Example: If a therapist is skilled at providing reinforcement but struggles with a teaching technique, supervisors can focus observations on the weaker area to provide targeted feedback.

The Role of Interobserver Agreement (IOA)

IOA helps ensure that data collection is accurate by comparing the observations of two or more individuals. Combining IOA with procedural integrity measurements ensures both the interventions and the data are reliable.

Procedural integrity ensures that interventions are implemented as intended, which directly impacts their effectiveness. By monitoring accuracy, dosage, and procedural fidelity, we can improve outcomes and provide better support for students and clients.

Understanding these processes helps parents and teachers advocate for interventions that are both high-quality and personalized.
