Introduction : People living with type 2 diabetes are brought to make demanding behavioral changes that can lead to self-management difficulties.Background : The guidelines recommend that healthcare professionals follow a person-centered approach (PCA) when caring. However, this approach seems difficult to adopt in practice.Objective : Coconstruct an intervention inspired by the concept map (CM) to promote the adoption of PCA by nurses during self-management support encounters.Method : This study is based on a model for developing evidence-based nursing interventions. Five experts (2 patients, 2 nurses, 1 educational specialist) collaborated in the coconstruction of the intervention.Results : The Person-Centered Approach Diabetes Self-Management Support (PCA-DSMS) intervention has been developed in accordance with the foundations of a PCA and the CM. It includes four steps : 1) Introduce the intervention ; 2) Develop the Needs Map ; 3) Intervene according to priority needs ; 4) Conclude and plan a follow-up.Discussion : More studies are needed to explore whether the intervention is acceptable and feasible as well as its ability to lead nurses to adopt PCA.Conclusion : The PCA-DSMS could bring nurses to adopt a PCA.
