Protocol for a Pilot Randomized Controlled Mixed Methods Feasibility Trial of a Culturally Adapted Peer Support and Self-Management Intervention for African Americans.

backgroundDue to diabetes disparities commonly seen among African Americans, it is important to address psychosocial and sociocultural barriers to medication adherence among African Americans with diabetes. Building on our prior work testing a culturally adapted peer supported diabetes self-management intervention for African Americans, this study will conduct a pilot randomized controlled feasibility trial that compares the culturally adapted intervention with a standard diabetes self-management program.

methodsUsing an intervention mixed-methods design, the six-month trial will be conducted at two sites. Twenty-four African Americans with uncontrolled type 2 diabetes will be randomized to the intervention or control arm. Feasibility and acceptability outcomes in four domains (recruitment, intervention acceptability, intervention adherence, retention) will be collected. Primary clinical outcome (A1C), secondary outcome (medication adherence) and patient-specific psychosocial measures will be collected at baseline, 2 months, and 6 months. Document review, interview and focus groups will be used to gather qualitative data on feasibility and acceptability.

resultsExpected results are that the trial protocol will be feasible to implement and acceptable for participants, and there will be a signal of clinically meaningful reduction in A1C and improvements in medication adherence.

conclusionsThe results of this trial will inform a future powered large-scale randomized controlled trial testing the effectiveness of the culturally tailored intervention.
