What occurs during a forced choice or paired choice preference assessment?

During a forced choice or paired choice preference assessment, items are indeed presented in pairs, preventing the client from selecting both. This method is designed to help identify preferences by forcing the individual to make a choice between two options at a time. By doing so, it becomes clearer which item is favored over the other based on the client's selection.

This approach contrasts with other methods of assessing preferences, such as presenting items separately or randomly. When items are observed separately, it doesn't give the same clarity on preference as the comparison between two items does. Random placement in the environment might lead to less structured assessments and could confuse the client if they are unsure about what is available or how to choose. Additionally, presenting only one item at a time does not facilitate a direct comparison of preferences, as there is no alternative for the client to choose from in that moment. Thus, the paired choice method effectively narrows down preferences by facilitating clear and direct comparisons between pairs.
