Congratulations to our 2026 Appreciative Inquiry-Based D&I Course cohort for completing our five-week course — Innovative D&I Approaches: Appreciative Inquiry and Discrete Choice Experiments! This year’s course focused on designing and applying Discrete Choice Experiments to sustain evidence-based HIV programs for adolescents and young adults in resource-constrained settings.  After an expert review process, eight participants were chosen from more than 75 applicants to represent each PATC³H-IN clinical research center.  Over five weeks, participants learned about the principles of appreciative inquiry and implemntation science and were trained on how to administer, apply, and analyze discrete choice experiments. 

Over the remainder of their year with INSPIRE, course participants will serve as liaisons for a shared discrete choice experiment at their respective PATC³H-IN clinical research centers. They will go through the ethical review process, collect and analyze data, and contribute to a manuscript on the experiment. 

We were more used to quantitative studies before now. Then we began to understand appreciate that mixed-method studies were better and richer than simple quantitative studies. It was a profound excitement for me to discover in this course something called “DCE” (Discrete Choice Experiments)… Taking this course will take you to another level in research.
