What is the purpose of a Stimulus Preference Assessment?

The purpose of a Stimulus Preference Assessment is primarily to determine preferences. This assessment is designed to identify items or activities that an individual is likely to find reinforcing, which can then be used to motivate and engage them during interventions or learning activities.

Stimulus Preference Assessments help practitioners pinpoint what stimuli are most appealing to a person, which can significantly enhance the effectiveness of behavioral interventions. By knowing what a person prefers, technicians can tailor their approach, using these motivating items to increase engagement and improve outcomes in therapies for individuals with autism.

While evaluating behavior, assessing needs, and collecting data are important aspects of working with individuals on the autism spectrum, they do not capture the specific aim of identifying preferred stimuli that the assessment is designed to achieve. Understanding preferences is foundational to building effective and individualized treatment plans.
