Abstract

Individuals with intellectual or developmental disabilities are able to reliably express their likes and dislikes through direct preference assessment. Preferred items tend to function as rewards and can therefore be used to facilitate the acquisition of new skills and promote task engagement. A number of preference assessment methods are available and selecting the appropriate method is crucial to provide reliable and meaningful results. The authors conducted a systematic review of the preference assessment literature, and developed an evidence-informed, decision-making model to guide practitioners in the selection of preference assessment methods for a given assessment scenario. The proposed decision-making model could be a useful tool to increase the usability and uptake of preference assessment methodology in applied settings.
