The stability of stimulus preference assessment results is an important consideration when using the identified stimuli in treatments and/or additional experiments. Prior research has demonstrated that the preference hierarchies identified by the multiple stimulus without replacement (MSWO) preference assessment are generally stable over time. This stability has been demonstrated with tangible and edible items, yet the extent to which that stability can be expected for other types of stimuli remains unknown. The current study tested the 2-month stability of the MSWO preference assessment in the context of college students' preferred sexual partners. Adequate stability was shown in most cases, suggesting generality of the stability of preference across tasks, populations, and stimuli.
