Abstract

Objective: To compare the effectiveness of three delivery modalities of Decision-making Education for Choices In Diabetes Everyday (DECIDE), a nine-module, literacy-adapted diabetes and cardiovascular disease (CVD) education and problem-solving training, compared with an enhanced usual care (UC), on clinical and behavioral outcomes among urban African Americans with type 2 diabetes.

Research design and methods: Eligible participants (n = 182) had a suboptimal CVD risk factor profile (A1C, blood pressure, and/or lipids). Participants were randomized to DECIDE Self-Study (n = 46), DECIDE Individual (n = 45), DECIDE Group (n = 46), or Enhanced UC (n = 45). Intervention duration was 18-20 weeks. Outcomes were A1C, blood pressure, lipids, problem-solving, disease knowledge, and self-care activities, all measured at baseline, 1 week, and 6 months after completion of the intervention.

Results: DECIDE modalities and Enhanced UC did not significantly differ in clinical outcomes at 6 months postintervention. In participants with A1C ≥7.5% (58 mmol/mol) at baseline, A1C declined in each DECIDE modality at 1 week postintervention (P < 0.05) and only in Self-Study at 6 months postintervention (b = -0.24, P < 0.05). There was significant reduction in systolic blood pressure in Self-Study (b = -4.04) and Group (b = -3.59) at 6 months postintervention. Self-Study, Individual, and Enhanced UC had significant declines in LDL and Self-Study had an increase in HDL (b = 1.76, P < 0.05) at 6 months postintervention. Self-Study and Individual had a higher increase in knowledge than Enhanced UC (P < 0.05), and all arms improved in problem-solving (P < 0.01) at 6 months postintervention.

Conclusions: DECIDE modalities showed benefits after intervention. Self-Study demonstrated robust improvements across clinical and behavioral outcomes, suggesting program suitability for broader dissemination to populations with similar educational and literacy levels.

Each line is derived from a piecewise linear mixed-effects model with treatment arm dummy coded as a predictor and adjusting for age, years of education, and PHQ-2 score. The model consists of an intercept and two slopes (baseline to postintervention and postintervention to 6 months postintervention).
