Brief Summary:

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.

This study will assign African-American diabetics to either text messages, health coaches, or enhanced care to find out which one works better. The investigators especially want to find out if one works better for people at highest risk. Lastly, the investigators want to find out if messages or coaches help people improve their blood sugar, quality of life, and their feelings about primary care.

The study will test messages, coaches, and enhanced care side by side in primary care doctors' offices. The messaging and coaching programs will give patients pretty much the same information, but in different ways. The text messages will be written carefully based on each patient's needs and interests. The coaches will be trained in how to help people get motivated and work to reach their health goals.

This study will include 646 African-American adults, ages 18 and above, with uncontrolled diabetes and one or more additional chronic condition, living in medically underserved communities. People will have to have a cell phone or smart phone with texting capability and be able to use it to participate. 258 participants will get messages, 258 will get coaches, and 130 will receive enhanced care.

The investigators will be able to tell if messages and coaches work by seeing if people improve their diabetes self-care decisions, and if their blood sugar, quality of life, and feelings about primary care get better. The long-term study goal is to get primary care clinics all over the country to start using motivational messages or health coaches if they work well.

Arm Intervention/treatment
Experimental: Text Messaging (TM)
The TM intervention will use an extensive text message library focused on 3 key behavioral areas (diet, exercise, and medication adherence). The TM intervention will incorporate supportive cognitive behavioral strategies such as goal setting, positive reinforcement, self-talk and dealing with barriers to change. Messages will encourage social interaction (social support, problem-solving, and feedback), self-monitoring of diet and exercise, diet modification, physical activity advice and prompting and basic self- regulatory skills. Messages will be tailored based on participant demographics, health literacy, and preferences.
Behavioral: Text Messaging (TM)
As specified in the arm description above

Experimental: Health Coaching (HC)
The HC intervention will place emphasis on the coach establishing rapport with the participant and assessing and establishing their initial goals using motivational interviewing, HC program goals, plans for future individual sessions. A written copy of personal health goals will be given to patients at the end of the first session. Coaches will aim to meet with participants for individual HC sessions bi-monthly the first 2-3 months followed by monthly for 8 - 9 months to provide information and support regarding health habits focusing sessions on areas related to patient-identified health goals, needs, and barriers to change. Sessions can occur in person or by phone based on patient preference.
Behavioral: Health Coaching (HC)
As specified in the arm description above

Active Comparator: Enhanced Usual Care (EC)

All participants in all 3 study arms (TM, HC, and EC) will receive enhanced usual care. Usual care in the participating practices will be supplemented through the following key EC resources:

A. Patient-focused Resources including: 1) MODEL Program Toolkit, and 2) low literacy diabetes educational materials.

B. Availability of diabetes support services including: 1) peer group support sessions, 2) diabetes education, 3) resources, and 4) Diabetes Coalition education hub resources.

C. Practice-focused components including: 1) practice training/continuing medical education, and 2) reporting of diabetes performance measures.

Primary Outcome Measures :
  1. Diabetes Self-Care Activities [ Time Frame: 1 year ]
    The Revised Summary of Diabetes Self-Care Activities Questionnaire (SDSCA) assesses DM self-care over the previous 7 days for 7 core behaviors: smoking, diet, exercise, blood sugar testing, foot care, smoking, and medication adherence (12 items)

Secondary Outcome Measures :
  1. Diabetes-Specific Quality of Life [ Time Frame: 1 year ]
    The Diabetes-39 has 5 domains: DM control, Anxiety and worry, Social burden, Sexual functioning, and Energy and mobility

  2. Primary Care Engagement [ Time Frame: 1 year ]
    Selected National Health Interview Survey (NHIS) questions assess 3 primary domains: (a) Usual source of care when sick; (b) Usual source of preventive care; and (c) Delay in needed care

  3. Quality of Care [ Time Frame: 1 year ]
    The Patient Assessment of Chronic Illness Care (PACIC) measures specific actions or qualities of care based on Chronic Care Model

  4. Average Blood Sugar (A1c) [ Time Frame: 1 year ]
    The Hemoglobin A1c blood test assesses average blood sugar over the past 6 weeks to 3 months
