Moeilijk te bereiken? Een kwestie van werving Effectieve wervingsstrategieën om de vertegenwoordiging van mensen met een laag opleidingsniveau in gezondheidsonderzoek te verhogen

Recruiting participants with a low level of education for health research is difficult but crucial to reduce health inequalities. To give practical insights on how to improve representation, this study investigates how people with different levels of educational attainment are recruited to register in the Dutch Brain Research Registry Hersenonderzoek.nl (N = 20,705). The recruitment channels studied are social media, traditional media, family and friends, medical professionals, and patient organizations. Our results show that social and traditional media and medical professionals recruit more diverse segments of the population, whereas patient organizations and family and friends mostly recruit highly educated participants. These results imply that, to create diverse samples, we need to utilize recruitment channels that low status groups frequently access and that provide understandable and vivid explanations.
