The steps undertaken so far are critical prerequisites for our research agenda which aims advancing our understanding of the origins of social cohesion.
The first milestone was to develop a fully standardized tool to measure social cohesion among children as young as 3-years old. We have designed and rigorously pretested an age-appropriate, audio-visual, digital mobile app. This app is based on well-established experimental paradigms used for adults, adapted to address challenges such as children's limited attention, motivation, and competencies. Notably, its adaptability and scalability make it ideal for large-scale data collection efforts, while its availability in over 10 languages ensures its applicability across diverse cultural contexts.
Second, we established a collaboration with over 100 preschools, granting us access to their premises and, more importantly, to children from diverse backgrounds. We have assembled a unique dataset covering 3’499 children. We also achieved an unusually high participation rate among parents (2’300) and teachers (399). In addition, we have secured access to unique administrative data on preschools, including structural quality indicators and data on preschools' waiting lists. Leveraging machine learning techniques, we developed an algorithm to match this administrative data with our newly collected experimental and survey data on children, parents, and teachers. The ultimate goal is to generate a predictor for families’ sorting into preschools and single out the random component determining the final choice.
Together with practitioners, we have developed a tailored parenting program designed to foster responsive caregiving. This program comprises non-verbal, gender/race-neutral animated video clips, delivering practical parenting tips. A first version was piloted in spring 2023. The implementation of a refined version of the parenting program and the evaluation of its short-term effects on parenting style and potential spill-over effects on children’s social behavior is scheduled for the academic year 2024/25. We have also set the grounds for an intervention designed to strengthen social cohesion in preschools. Employing an observation-based approach, we gathered detailed data on the quality of teacher-child interactions and documented their relation with children’s discriminatory behavior. The next step is to prepare a teacher manual on how to foster social cohesion in their institutions.
