A detailed description can be found in our protocol paper ([Popp et al., 2021][1]). ---------- *Aim of the study* This study aims to evaluate the transfer of cooperative planning, a co-creation strategy, into new settings and to explore related key determinants. *Intervention strategy* Cooperative planning was utilised to target physical activity promotion in three German real-world settings in the sectors of nursing care and automotive mechatronics, involving researchers, practitioners, and policymakers who conjointly develop new measures for physical activity promotion. A logic model generated for this co-creation process describes the underlying assumptions and guides the evaluation. *Study design and methods* Following principles of a pragmatic evaluation, this study uses a mixed methods design to evaluate the transfer of cooperative planning and its determinants across three different settings. Quantitative and qualitative data is collected via questionnaires, documents, and interviews. ---------- *Funding* The research network [Capital4Health][2] and the associated subproject [PArC-AVE][3], in which the study is conducted, are funded by the German Federal Ministry of Education and Research [grant number 01EL1821A].
