The American Diabetes Association (ADA) "Standards of Medical Care in Diabetes" includes the ADA's current clinical practice recommendations and is intended to provide the components of diabetes care, general treatment goals and guidelines, and tools to evaluate quality of care. Members of the ADA Professional Practice Committee, a multidisciplinary expert committee (https://doi.org/10 .2337/dc20-SPPC), are responsible for updating the Standards of Care annually, or more frequently as warranted. For a detailed description of ADA standards, statements, and reports, as well as the evidence-grading system for ADA's clinical practice recommendations, please refer to the Standards of Care Introduction (https://doi.org/10.2337/dc20-SINT). Readers who wish to comment on the Standards of Care are invited to do so at professional.diabetes .org/SOC. Effective behavior management and psychological well-being are foundational to achieving treatment goals for people with diabetes (1,2). Essential to achieving these goals are diabetes self-management education and support (DSMES), medical nutrition therapy (MNT), routine physical activity, smoking cessation counseling when needed, and psychosocial care. Following an initial comprehensive medical evaluation (see Section 4, "Comprehensive Medical Evaluation and Assessment of Comorbidities," https://doi.org/10.2337/dc20-S004), patients and providers are encouraged to engage in person-centered collaborative care (3-6), which is guided by shared decision-making in treatment regimen selection, facilitation of obtaining needed medical and psychosocial resources, and shared monitoring of agreed-upon regimen and lifestyle (7). Re-evaluation during routine care should include not only assessment of medical health but also behavioral and mental health outcomes, especially during times of deterioration in health and well-being. DIABETES SELF-MANAGEMENT EDUCATION AND SUPPORT Recommendations 5.1 In accordance with the national standards for diabetes self-management education and support, all people with diabetes should participate in diabetes self-management education and receive the support needed to facilitate the knowledge, decision-making, and skills mastery necessary for diabetes selfcare.
