Baseline information inclusion in preference assessments indicates:

• A. It includes the initial rate of the behaviors to be reduced
• B. It ignores the behavior rate
• C. It only documents the most preferred item
• D. It is not needed

Answer: (A)

Baseline data in a preference assessment captures how often the target behavior occurs before any intervention. That initial rate provides a quantitative starting point, allowing you to compare future data to show whether the treatment is reducing the behavior. It also helps you set realistic goals and assess whether the identified preferred items function effectively as reinforcers once the intervention begins. In short, baseline information reflects the starting level of the behavior you aim to reduce, which is essential for measuring change and guiding treatment decisions.
