A key component to any successful intervention aimed at increasing appropriate behavior for individuals with disabilities is the identification of potential reinforcers (Verriden & Roscoe, 2016). Preference assessments allow for the identification of specific preferred items for each individual; however, little is known about the stability of preference over time. The purpose of this review was to synthesize results from 20 studies that conducted two or more preference assessments, at least 24 h apart, and analyze the stability of preference assessment outcomes across repeated assessment administrations. This paper investigated the impact of the inter-assessment interval (IAI; i.e., how often assessments were conducted), preference assessment format, and stimulus type (i.e., leisure items/activities, edibles, social interaction) on the stability of preference assessment outcomes. Results suggest that, across repeated administration, preference is most stable at brief IAIs (8-30 days) and when using the pairedstimulus format (Fisher et al., 1992). Implications for practitioners and future research are discussed.
