Implementing Discrete Choice Experiments using Ngene and Qualtrics

Discrete choice experiments are widely used in the social sciences to understandindividuals’ stated preferences. Given their popularity, many diQerent software packages,such as Ngene, are available to create discrete choice experiment designs. However,integrating these designs into online platforms like Qualtrics can be time-consuming andoften challenging. This paper addresses these challenges and provides a detailed tutorial onconverting Ngene outputs into a Qualtrics-compatible format using custom code andintegrating it into Qualtrics to create a fully functional online discrete choice experiment. Theprovided code simplifies the process, making it more accessible and manageable forresearchers. This approach minimizes time and eQort and potential human errors whenintegrating the design into the online survey platform. Lastly, the paper provides code forextracting and formatting the post-experiment choice data into a meaningful data format thatcan be used for data analysis. In sum, this paper equips researchers with tools to easilydeploy discrete choice experiment designs created using the Ngene software to Qualtrics anddata extraction post-data collection.
