Mental Health History and DECIDE (Decision-Making Education for Choices in Diabetes Everyday) Diabetes Support Program Outcomes Among African Americans With Type 2 Diabetes

Purpose The purpose of this study was to determine behavioral and clinical outcomes of the DECIDE (Decision-Making Education for Choices in Diabetes Everyday) diabetes support program trial participants with and without a mental health (MH) history by treatment arm. Methods A secondary analysis was conducted of data from the DECIDE trial sample of urban African American adults with type 2 diabetes (T2DM; N = 137) who received the DECIDE diabetes support program in 1 of 3 delivery formats: self-study (n = 46), individual (n = 45), and group (n = 46). Positive screen on the Patient Health Questionnaire-2 and/or reported MH diagnosis were coded as MH history. Self-management, knowledge, problem-solving, and A1C data at baseline and 1 week and 6 months postintervention were analyzed for participants with and without MH history. Results Prevalence of MH history was 37% in the sample. Among those with no MH history, knowledge and problem-solving improved at 6 months postintervention in all intervention arms. For those with MH history, knowledge and problem-solving improved in the self-study and individual arms but not in the group arm. Clinically but not statistically significant changes in A1C were observed at 6 months. Conclusions In an urban minority T2DM sample, those with an MH history benefited from the intervention, but delivery format mattered, with robust improvements when participants with an MH history received self-directed or one-on-one formats rather than group.
