The overall goal of this study is to compare how well motivational messages (text messages from the doctor's office), diabetes health coaches, and enhanced usual care with diabetes education materials (provided at the doctor's office) work to help African-American adults with uncontrolled diabetes improve their diabetes self-care decisions. Self-care is difficult when you have diabetes, especially when patients have other medical conditions, their diabetes is uncontrolled, and when they live in an area without many primary care doctors. Many studies have show that encouraging text messages from the doctor's office and health coaches can help people take better care of themselves. But before primary care clinics around the country start trying to send texts, hire health coaches, or provide additional educational materials it is critical for them to know which approach is more likely to help.
