What is baseline data in ABA?

Baseline data in ABA, or Applied Behavior Analysis, refers specifically to the data collected before an intervention is implemented. This initial measurement provides a reference point for understanding the current state of the behavior in question. By assessing the behavior prior to any treatment, practitioners can establish a clear picture of the frequency, intensity, or duration of the behavior, which allows for a comparison after the intervention has been applied.

This comparative analysis is vital because it helps in determining the effectiveness of the intervention by highlighting any changes in the behavior that may occur as a result of the treatment. Without established baseline data, it would be challenging to accurately assess whether an intervention has been successful in modifying the target behavior.
