Developing a policy game intervention to enhance collaboration in public health policymaking in three European countries.

<bold>Background: </bold>One of the key elements to enhance the uptake of evidence in public health policies is stimulating cross-sector collaboration. An intervention stimulating collaboration is a policy game. The aim of this study was to describe the design and methods of the development process of the policy game ‘In2Action’ within a real-life setting of public health policymaking networks in the Netherlands, Denmark and Romania.<bold>Methods: </bold>The development of the policy game intervention consisted of three phases, pre intervention, designing the game intervention and tailoring the intervention.<bold>Results: </bold>In2Action was developed as a role-play game of one day, with main focus to develop in collaboration a cross-sector implementation plan based on the approved strategic local public health policy.<bold>Conclusions: </bold>This study introduced an innovative intervention for public health policymaking. It described the design and development of the generic frame of the In2Action game focusing on enhancing collaboration in local public health policymaking networks. By keeping the game generic, it became suitable for each of the three country cases with only minor changes. The generic frame of the game is expected to be generalizable for other European countries to stimulate interaction and collaboration in the policy process. [ABSTRACT FROM AUTHOR]
