In applied behavior analysis (ABA), selecting a measurement procedure for obtaining representative procedural integrity data involves careful consideration of the relevant dimensions of the intervention (e.g., accuracy and dosage) and environmental constraints.
Procedural integrity refers to the extent to which an intervention is implemented as intended, and accurately measuring it ensures the validity of the intervention’s outcomes.
If you’re preparing for the BCBA exam, understanding how to measure procedural integrity is essential for aligning your interventions with ethical and data-based standards.

1. Identify Key Dimensions for Measurement
Key dimensions of procedural integrity, such as accuracy and dosage, need to be defined based on the intervention.
For example:
- Accuracy measures how closely each step of the procedure aligns with the planned intervention protocol.
- Dosage refers to the frequency, duration, or intensity with which the intervention is administered.
2. Choose Appropriate Measurement Methods
Direct Observation
This is one of the most common methods in ABA for assessing procedural integrity, where a trained observer records whether each step of the protocol is implemented accurately.
This method provides real-time data but may be resource-intensive.
Permanent Product Measurement
In some cases, evidence of intervention steps can be measured through products left after the intervention (e.g., completed worksheets).
This approach can be less intrusive but may not capture all dimensions, like dosage or timing.
For related examples, see ABA case studies in practice.
Self-Report Checklists
Practitioners can use structured checklists to self-monitor procedural adherence, which is practical in settings with limited resources.
However, it may be less reliable than direct observation due to potential biases.
You can also explore remote BCBA supervision options to improve accuracy through professional oversight.
3. Account for Environmental Constraints
Resource availability, setting logistics, and time constraints should inform the measurement procedure choice.
For instance, in settings with limited personnel, self-report or permanent product recording might be more feasible than direct observation, even if it sacrifices some degree of accuracy.
To ensure ecological validity, see essential BCBA exam resources for examples of how these constraints are addressed in applied settings.
4. Sample Representatively
Procedural integrity should be measured regularly but practically, considering the consistency of implementation.
Sampling strategies might include continuous sampling for high-risk interventions or intermittent sampling for less intensive interventions.

Why Procedural Integrity Matters in ABA
Selecting the right measurement procedure helps ABA practitioners ensure that interventions are implemented as designed and that integrity data accurately reflects performance.
Maintaining procedural integrity ensures reliable treatment outcomes, strengthens ethical accountability, and promotes evidence-based practice.
