A Pilot Intervention Study of Health Coaching to Promote Diabetes Self-Care in the Community

Diabetes and its complications pose a substantial physical, psychological and financial burden on the large number of racial/ethnic minorities and other socioeconomically deprived persons with diabetes. However, self-management goals are often not met in racial/ethnic minorities and in populations with fewer socioeconomic resources. In response, our research team has developed a novel "health coaching" intervention to promote diabetes self-management in the community. Health coaching is based on Control Systems Theory and helps patients to: 1) identify problems in self-care behaviors; 2) create dynamic plans for correcting these issues; and, 3) learn to navigate the complexities of everyday life and to achieve clinically and personally desirable outcomes. The primary innovation of the present project is that first-year medical students are trained to serve as the health coaches, and are participating in the study Coaching for Control (STU00069506). The objective of our pilot study is to test whether 20 patients from five Northwestern Medicine primary care practice groups (two in the Austin community, two at Northwestern Memorial Hospital and one at Norwegian American Hospital) enrolled in the "Coaching for Control" intervention experience favorable changes in clinical and behavioral outcomes after 16 weeks as compared with an equal number of patients from those same clinics who are not enrolled in the program. We will use a non-randomized trial design to carry out the following aims: 1. Determine whether patients with diabetes who participate in the "Coaching for Control" behavioral intervention program (i.e., the intervention arm) have lower hemoglobin A1c (HbA1c) after four months than patients who do not participate in the program (i.e., the control arm). 2. Determine whether diabetes patients in the intervention arm report higher task-related self-efficacy for initiating and maintaining recommended diabetes self-care behaviors than participants in the control arm. We hypothesize that participants in the intervention arm will have more favorable HbA1c and report higher self-efficacy for diabetes self-care behaviors than participants in the control arm. Secondary objectives are to test whether these changes persist 8 months after the program ends and to test whether we observe changes in additional clinical measures such as blood pressure, waist circumference, and in self-reported health behaviors such as medication adherence, self-care behaviors, physical activity and diet. Process evaluations through focus groups and interviews with participants will allow us to refine our intervention. The translational aspects of our proposal include the application of a proven intervention to promote diabetes self-care in a community setting that includes adults at high risk for diabetes complications. Findings from the present pilot study will be used to justify expansion of the study to a larger group of community members so that we can carry out a larger randomized trial of efficacy.
