Implementing Multistage Transdisciplinary Modeling for Policy Interventions: An Approach to System Dynamics and Stakeholder Discourse to Maximize Impacts in Austrian Grassroots Sports

ABSTRACT Efficient allocation of financial resources through policy interventions is vital for fostering grassroots sports and promoting preventive health measures. However, the intricacies of impact‐oriented grassroots sports subsidies are shaped by factors within a specific funding cascade and the broader societal context. Addressing this complexity requires a methodology that provides a comprehensive, systems perspective, considering diverse stakeholder knowledge. This paper advocates for the use of system dynamic modeling and stakeholder engagement as a promising approach to empower evidence‐based policy interventions. The transdisciplinary process, emphasizing equal collaboration between science and practice, aims to synergize the modeling. The study showcases the application of a multistage transdisciplinary modeling process for enhancing impact‐oriented public grassroots sports funding in Austria that is aligned with the EU Structural Reform Support Programme for evidence‐based policymaking. The multistage transdisciplinary modeling process is considered as a tool for facilitating the development of system interventions and addressing complex societal problems.
