A supportive organizational context is important for successfully implementing evidence-based practice (EBP). Managers have an important role in creating organizational prerequisites for EBP. The present study compared how top- and middle-level managers describe the process of implementing EBP and the factors influencing this process. Data were collected through interviews with twenty-two managers in social services, and analysed with thematic deductive analysis based on the Theoretical Domains Framework (TDF) and the COM-B model. Findings showed that top-level managers focused more on strategic- and system-level issues, e.g. external comparisons, dialogue with authorities and creating support systems, while the middle managers focused on the operative implementation at staff level, i.e. motivating and involving staff. Furthermore, the two groups had different understandings of EBP. To conclude, there needs to be an alignment in the understanding of, and support for, EBP between the different levels of managers. To create a mutual understanding of what EBP entails and to clearly communicate how the organization applies the different steps of the EBP process could be crucial steps in enabling the implementation of EBP, and needs to be done in dialogue between middle- and top-level managers.
