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.
