Description of a Practitioner Model for Identifying Preferred Stimuli With Individuals With Autism Spectrum Disorders

Abstract

The rich technology of stimulus preference assessment (SPA) is a product of 40 years of experimental research. Basic principles of reinforcement and a modest empirical literature suggest that high-preference stimuli identified via SPA may enhance treatment efficacy and decrease problem behavior more effectively than less-preferred stimuli. SPAs can be conducted using one of several methods associated with different time requirements and outcomes. Despite the broad applicability of preference assessments, we are unaware of widely available practitioner guidelines that prescribe when to use SPAs, how to select and modify specific SPA procedures, and how to supplement SPAs with other procedures for maximizing performance. The purpose of the current article is to describe a model for practitioners to select and conduct preference assessments based on practical considerations and research findings. Data are also reported from the application of the proposed model to preference assessments for 20 individuals diagnosed with autism spectrum disorders.
