While social programs are often assessed using short-term impact studies, longitudinal designs allow evaluators to capture change over time, identify longer-term outcomes, adapt instruments, and better understand participants in transition. A mixed methods design can be critical in understanding these dynamics; yet there is a lack of literature exploring the practical considerations of planning and conducting qualitative and quantitative data collection and analysis within longitudinal studies. This paper examines two different mixed methods frameworks used in a 5-year evaluation of three youth entrepreneurship programs in East Africa. We show how the evaluation team dealt with unique challenges across methods and over time, and how the design ultimately facilitated a richer understanding of program impacts and processes. Considerations for conducting this type of study are explored, related to the impact of longevity on analysis and research staff. Successfully using a longitudinal mixed methods approach requires researchers to be strategic and reflexive, and work in close collaboration.

Creating original, integrated multiple-choice questions (MCQs) is time-consuming and onerous for basic science and clinical faculty. We demonstrate that medical students are co-experts to overcome assessment challenges of the faculty. We recruited, trained, and motivated medical students to write 10,000 high-quality MCQs for use in the foundational courses of medical education. These students were ideal because they possessed integrated knowledge (basic sciences and clinical experience). We taught them how to write high-quality MCQs using a writing template and continuous monitoring and support by an item bank curator. The students themselves also benefitted personally and pedagogically from the experience., (© The Author(s) under exclusive licence to International Association of Medical Science Educators 2024.)
