In the behavior-analytic field, preference assessments are conducted to determine specific items to use as reinforcers to reduce aberrant behavior as well as increase appropriate behavior. We examined the consistency of preference-assessments results among individuals with Alzheimer’s Disease (AD) to ensure effective reinforcers are used in behavioral interventions. Specifically, we examined if identified reinforcers remained consistent for individuals with AD throughout the study or if preferences shifted. The experimental procedure consisted of a series of multiple-stimulus preference assessments without replacement (MSWO); data were analyzed for preference shifts. Results showed variability with one individual’s preferences, whereas the other individual’s preferences remained relatively stable.
