What is the purpose of establishing a baseline in behavior assessment?

Establishing a baseline in behavior assessment serves the crucial function of providing a point of comparison for measuring change. A baseline reflects the individual's behavior prior to any intervention and serves as a reference point against which future behavior can be evaluated. By comparing the data collected after the intervention to the baseline data, practitioners can assess the effectiveness of the intervention and determine whether there has been a significant change in behavior.

This comparison is essential in applied behavior analysis (ABA) because it allows for clear and objective measurements of progress. It helps practitioners make informed decisions about the interventions being used and can guide further programming and modifications as necessary. Having a clear baseline ensures that any observed changes can be attributed to the intervention rather than other variables, thus reinforcing the integrity of the behavioral assessment process.
