Family dyad-focused diabetes self-management intervention (FDSMI) for African American adults with type 2 diabetes:...

Type 2 diabetes is a major risk factor for serious long-term complications; African Americans (AAs) are especially vulnerable as compared to other racial groups. Multiple factors at individual, interpersonal, community, societal, and healthcare system levels contribute to greater difficulty in diabetes self-management. Social support can be a mediating factor.

We will examine a family-dyad-focused intervention to facilitate family support to promote diabetes self-management among middle-aged and older adult AAs with type 2 diabetes (T2D).

We propose a small phase I/II randomized controlled trial (RCT) using virtual group sessions to examine: (1) the feasibility, acceptability and preliminary efficacy of a 10-session dyad-focused diabetes intervention for AA adults with T2D and their family members; and (2) the associations of dyadic lifestyle behaviors and relationships to healthy behaviors and health outcomes over time in patients with T2D. We will recruit 208 AA adult participants (104 patient-family member dyads). Adults with diabetes and A1C > 7.0 % paired with their designated family members will be randomized 1:1 to the intervention or control arm (52 dyads per arm). Each dyad randomized to the intervention arm will receive 1) group sessions focusing on diabetes self-management, behavioral changes and strategies to cope with stress; 2) family dyadic-focused support component in each session; and 3) three individual family telephone feedback sessions. We will collect data at baseline, post-intervention (Month 3) and six-month post-intervention follow-up (Month 9).

Findings will provide foundational data to guide future implementation studies of family-dyad interventions for adult AAs with T2D.
