How to Conduct a Multiple-Stimulus Preference Assessment
By Master Trainer Cassie Herman
There are several different types of preference assessment. In previous behavioral briefs, we reviewed a Free Operant Observation Preference Assessment and a Paired-Stimulus Preference Assessment. This Behavioral Brief will focus on Multiple-Stimulus Preference Assessment (MS).
There are two different types of Multiple-Stimulus Preference Assessments:
- Multiple-Stimulus with Replacement
- Multiple-Stimulus without Replacement (MSWO)
Both assessments will be discussed within this Behavioral Brief.
A Multiple-Stimulus without Replacement Preference Assessment is similar to a Paired-Stimulus. This is because they both identify high-preference, moderate-preference, and low-preferred items. The data is displayed in a hierarchy. This assessment can be completed in less time than both Pair-Stimulus and Free Operant Preference assessment.
The limitation of the Multiple-Stimulus assessment is that the individuals must have strong scanning repertoire due to an array of 5 to 7 items being presented (DeLeon & Iwata, 1996). If the individual does not have a strong scanning repertoire then the Free Operant, Single-Stimulus or a Paired-Stimulus should be conducted.

Identifying a high-preferred reinforcer is a crucial component in the creation of a behavior change program. Stay tuned for our 3rd installment on Stimulus Preference Assessments. In this behavioral brief we will be discussing Multiple-Stimulus Preference Assessments!
