Participatory co-design of science communication strategies for public engagement in the US and Ecuador around health behaviour change

Science communication research and practice currently promote strategies oriented towards creating audience engagement around scientific content. Consequently, science communication needs to continually explore new methodologies that enable audiences’ participation in order to meet their interests and needs. The present study combines qualitative and participatory action research (PAR) methods guided by decolonial epistemologies to develop a co-designed project with public health, nutrition and sports science researchers to recruit young audiences from Albuquerque, New Mexico, USA, and from Cuenca, Ecuador. The main goal of this study was to create strategies to motivate young audiences’ engagement and interest in adopting healthy habits. This article focuses on the study’s research design in order to provide guidelines and procedural recommendations for facilitating a co-design approach for developing science communication initiatives targeting children and teenagers in Ecuador and the United States. As we demonstrate, the PAR approach for co-design leads to useful outcomes: (1) the incorporation of decolonial theory guidelines in participatory research; and (2) the development of science communication strategies that combine online and offline activities to put in dialogue scientists and their audiences, ultimately resulting in mutual learning, thus allowing scholars and practitioners to explore in practical terms how to co-design improved strategies.
