What should a written description of a preference assessment include?

• A. The behavior(s) to be reduced, the baseline rate, the antecedent, consequence, and replacement interventions, and the plan to monitor effectiveness
• B. A list of preferred items only
• C. The IOA data alone
• D. A safety protocol

Answer: (A)

A written description of a preference assessment should show how the identified preferences are used to support real changes in behavior. It’s not enough to list items; the description should tie the assessment to a plan for reducing challenging behavior or increasing appropriate behavior. Including the behavior to be reduced helps you know what you’re aiming to impact. Recording the baseline rate provides a starting point to judge change over time. Outlining the typical Antecedent and Consequence conditions helps clarify when reinforcement will be available and how the learner’s behavior will be reinforced, so you can interpret the results of the assessment correctly. Specifying replacement interventions shows what the learner will do instead of the problem behavior, which is essential for teaching alternative, more appropriate responses. Finally, including a plan to monitor effectiveness ensures you track progress and decide whether the chosen reinforcers are working or if adjustments are needed.

The other options don’t provide a complete picture. A list of preferred items alone doesn’t address how reinforcement will be used or measured. IOA data alone focuses on measurement reliability rather than describing how the preference assessment informs intervention. A safety protocol is important in some contexts but isn’t the content of a written preference assessment description.
