Many factors influence disease management and glycemic levels in children with type 1 diabetes (T1D). However, these concepts are hard to examine in children using only a qualitative or quantitative research paradigm. Mixed methods research (MMR) offers creative and unique ways to study complex research questions in children and their families. A focused, methodological literature review revealed 20 empirical mixed methods research (MMR) studies that included children with T1D and/or their parents/caregivers. These studies were examined and synthesized to elicit themes and trends in MMR. Main themes that emerged included disease management, evaluation of interventions, and support. There were multiple inconsistencies between studies when reporting MMR definitions, rationales, and design. Limited studies use MMR approaches to examine concepts related to children with T1D. Findings from future MMR studies, especially ones that use child-report, may illuminate ways to improve disease management and lead to better glycemic levels and health outcomes.
