Diabetes Knowledge/Information Arm
Subjects randomized to the diabetes knowledge/information arm will complete 12 diabetes education modules over a 12-week period. The educational materials were developed based on guidelines for diabetes education by the American Diabetes Association. The content is based on the principles of the Adult Learning Theory. The information is designed to be relevant, person centered, and presented in a non-threatening manner. The modules are designed to be delivered via telephone in 10-15 minutes, so that the maximum contact time per telephone call including introduction and closing would not exceed 30 minutes. Diabetes Knowledge/Information: This group will receive telephone-delivered diabetes knowledge/information lasting 30 minutes for 12 weeks.
Motivation/Behavioral Skills Arm
The motivation/behavioral skills intervention consists of patient activation (list of 5 questions to ask their provider at every visit and training on how to ask the questions), patient empowerment (diabetes responsibility contracts, personal goals, and flow charts for patients to record lab results/medications and training on how to use the empowerment tools), and behavioral skills training delivered via telephone lasting 30 minutes every week for 12 weeks. The behavioral skills training will be focused on 4 behaviors - physical activity, diet, medication adherence, and glucose self-monitoring. Guided by subjects' current problem areas and preferences, subjects will be asked to choose 1 of 4 behaviors to focus on every 3 weeks (4 behaviors over 12 weeks). Motivation/Behavioral Skills: This intervention consists of patient activation, patient empowerment, and behavioral skills training delivered via telephone lasting 30 minutes every week for 12 weeks.
Combined Intervention Arm
The combined intervention group will receive weekly telephone-delivered diabetes knowledge/information, patient activation (list of 5 questions to ask their provider at every visit and training on how to ask the questions), patient empowerment (diabetes responsibility contracts, personal goals, and flow charts for patients to record lab results/medications and training on how to use the empowerment tools), and behavioral skills training delivered via telephone. The behavioral skills training will be focused on 4 behaviors and guided by subjects' current problem areas and preferences, subjects will be asked to choose 1 of 4 behaviors to focus on every 3 weeks. The combined intervention group telephone sessions will last for 30 minutes. Combined Intervention: This group will receive all components of the diabetes knowledge/information and the motivation/behavioral skills interventions via telephone lasting 30 minutes every week for 12 weeks.
Usual Care Arm
The usual care group will receive weekly telephone-delivered general health education lasting 30 minutes for 12 weeks to control for attention. Patients in the usual care group will continue to receive any usual diabetes education provided by the clinic staff; however, they will not receive targeted diabetes knowledge/information, activation, empowerment, or behavioral skills training. Usual Care: This group will receive telephone-delivered general health education lasting 30 minutes for 12 weeks to control for attention and content.
