This upload contains the slides delivered at the workshop "Preregistration for team qualitative studies" at Open Science Festival Limburg in 2026. Abstract: Preregistration of research connotes publicly documenting your research design, including research questions, methods, and analysis plans. Although increasingly frequent in confirmatory studies, what may preregistration entail for qualitative research? What functions can it have within a team environment? During the gamified workshop we will explore the challenges and potential of preregistration, especially for collaborations accommodating different disciplinary, theoretical, and methodological backgrounds.
