other subgroups analyses will be performed through formal interaction tests for variables that will likely effect the intervention itself, such as age, gender and education level. A preliminary cost ‐ effectiveness analysis will be performed with the baseline measurement as control group from a societal and healthcare perspective. Healthcare costs for individual participants will be determined by multiplying resource use with corresponding unit prices for 2017, including doctor appointments, hospital emergency rooms and hospital admissions. Productivity losses for individual participants (lost productivity at paid work due to absenteeism and lost productivity at unpaid work) will follow from the PCQ. Utility values will be obtained through the EQ ‐ 5D ‐ 5L instrument. Dissemination An Advisory Board with experts from five countries (China, Croatia, Finland, the Netherlands and Sweden) has been set up. The Advisory Board will provide critical suggestions and comments throughout the project. The project team will disseminate the scientific project results through publications in scientific peer ‐ reviewed journals and conferences. We adopt the project website (http://sefacproject.eu/ ) to further disseminate the key findings of our project to all stakeholders. The European Local Inclusion and Social Action Network (ELISAN) will disseminate the project results through social media. DISCUSSION This paper describes the design of a prospective cohort study which aims to evaluate the effects of the SEFAC intervention for citizens at risk of or with T2DM and/or CVD on self ‐ management, healthy lifestyle behaviors, social support, stress, depression, sleep and fatigue, adherence to medications and HRQoL as well as the (cost ‐ ) effectiveness of the SEFAC intervention. Strengths of the study are that, to our knowledge, this study is the first to develop and implement an intervention combining the concepts of mindfulness, social engagement and ICT support in Europe. Our study may provide evidences on the generalizability of the intervention in different European countries through recruiting the target population in different settings. Additionally, the SEFAC project will provide information on cost ‐ effectiveness of self ‐ management programmes to fulfill the gap of limited data in this area. The study also has some limitations and challenges. Firstly, recruiting citizens at risk of or with T2DM and/or CVD may be a challenge. In order to increase the participation rates, open events aimed at recruiting participants will be held according to the capacity, organizational and environmental characteristics of the 4 study sites. Secondly, it was not practicable to include a control group. To ensure that a citizen would not feel excluded, we prefer to offer the intervention to all citizens that meet our criteria. Instead, we apply a 6 ‐ month pre ‐ post design, using the baseline measurement as the ‘control group’. Thirdly, we will try to capture the most important confounding factors in our questionnaire. However, it is still possible that we miss relevant variables. 8 213 A mindfulness-based intervention among adults with chronic conditons
