Dialogue moves are a pragmatic instrument that captures the most important categories of "dialogical intentions."This paper adapts this tool to the conversational setting of chronic care communication, characterized by the general goal of making reasoned decisions concerning patients conditions, shared by the latter. Seven mutually exclusive and comprehensive categories were identified, whose reliability was tested on an Italian corpus of provider-patient encounters in diabetes care. The application of this method was illustrated through explorative analyses identifying possible correlations between the dialogical structure of medical interviews and one of the indicators of personalized decision-making, namely the specificity of the recommendations given by the provider ("customization"). The statistical analyses show a significant correlation between the exchange of personal information and very specific and customized recommendations for change. It suggests how the creation of common ground, exceeding the boundaries of the paternalistic or patientcentered models, can lead to highly effective communication.
