In this two-phase mixed methods study, the investigators will first use patient feedback from semi-structured interviews to explore the ways in which patients with diabetes understand their diabetes and assess their disease control. The investigators will also use these interviews to elicit patient feedback on promising alternative communication formats to the hemoglobin A1C (A1C). In the second phase of the study, the investigators will test new formats to communicate information regarding diabetes control to patients with poorly controlled diabetes. This phase will be a three arm RCT comparing the effect of A1C (standard medical information) versus two alternative formats on several participant outcomes, primarily glycemic control at 6 months post-intervention.
