Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Study Aims: As a result, this research will use a pragmatic randomized trial to determine the comparative effectiveness of patient-driven TM versus HC versus EC for African-American adults with uncontrolled diabetes and multiple chronic conditions in MUA with an emphasis on identifying and quantifying important interactions between key baseline characteristics and treatment arm. Specific aims include: Aim 1-Quantify the effectiveness of TM, HC, and EC in improving the primary outcome measures (diabetes self-care activities related to general diet, exercise and medication adherence); Aim 2-Determine the contributions of six key, baseline patient characteristics: 1) urban vs. rural residence, 2) health literacy, 3) medical complexity, 4) social complexity, 5) smart vs. cell phone ownership, and 6) age, to the comparative effectiveness of TM, HC, and EC; and Aim 3-Quantify the effectiveness of TM, HC, and EC in improving secondary outcomes of average blood sugar, quality of life, and primary care engagement. The long-term objectives are to disseminate and foster implementation of the results of this research in MUA nationwide to improve critical self-care supports in primary care for our most vulnerable populations.
Overall study design: Pragmatic randomized clinical trial.
Main components of the intervention and comparator(s): The study will test two critical strategies for patient engagement that may lead to substantive improvements in the quality of care and outcomes most important to vulnerable patients with diabetes: 1) patient-driven TM, and 2) patient-driven HC. The two parallel primary care-based and patient-driven study interventions (i.e. TM and HC) have been designed to provide approximately the same content, but with two alternative delivery mechanisms. TM will incorporate supportive cognitive behavioral strategies to encourage improved diabetes self-care decisions and will be tailored based on participant demographics, health literacy, preferences, treatment self-regulation, perceived competency and reported barriers to self-care. Motivational interviewing focused HC will aim to meet with participants for individual HC sessions bi-monthly the first 2 months (Intensive Phase-4 sessions following randomization) followed by monthly for remaining 8 months (12 sessions total) to provide support regarding diet/weight loss, physical activity, and medication adherence tailored according to patient-identified health goals. Both strategies will be compared with EC with diabetes educational materials.
Study population: For the main comparative effectiveness analysis (Aim 1) the total sample size (after dropouts) is N=800 with 40% randomized to the TM arm (N1=320), 40% to the HC arm (N2=320), and 20% to the EC arm (N3 = 160). Participants include African-American adults, ages 35-75, with uncontrolled diabetes and multiple chronic conditions, living in medically underserved communities in the MidSouth who have a cell phone or smart phone with texting capability and complete a two-week run-in period demonstrating responsiveness to TM.
Primary/secondary outcomes: The primary outcome measures assessing effectiveness include: three (out of six total) subscales of the revised Summary of Diabetes Self-Care Activities questionnaire assessing general diet, exercise, and medication adherence. Secondary outcomes include: diabetes-specific quality of life using the Diabetes-39, primary care engagement using National Health Interview Survey questions regarding delayed needed care, and average blood sugar (A1c) obtained from medical records and reported in the DWPC-R.
Analytic methods: For Aim 1, in the context of repeated measures ANOVA, using t-tests within arm to detect change from baseline to 12-months (Follow-up 3), power exceeds 0.9 for all primary outcomes. For Aim 2, six analyses will assess heterogeneity of treatment effects by evaluating the interaction of each key, dichotomized, baseline characteristic with treatment arm, estimating means and standard errors of six subclasses, and within each characteristic (e.g. low or high health literacy) testing for differences between TM and HC, TM and EC, and HC and TM. Analyses for Aim 3 will be conducted as described above for Aim 1.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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.
Text Messaging (TM)
As specified in the arm description above
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.
Health Coaching (HC)
As specified in the arm description above
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) MyDiabetesCenter.org 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.
