MObile Support Adapted to Individual Contexts
MObile Support Adapted to Individual Contexts (MOSAIC Study)
Source: ClinicalTrials.gov · Last updated 5 Mar 2026
Brief summary (registry, in English)
This behavioral clinical trial evaluates an adaptively tailored, mobile phone-delivered intervention (MOSAIC) designed to support adults managing their type 2 diabetes. Adaptive means the intervention can change over time. Tailored means the intervention may be different for different participants. The main questions the study will aim to answer are: 1. Does the diabetes education and support delivered via the MOSAIC adaptive mobile phone-delivered intervention improve outcomes more than diabetes education and support delivered via print materials alone? This aim compares the study arms on outcomes such as glycemic management (hemoglobin A1c), diabetes distress, and psychosocial well-being. This aim also compares the study arms on intervention targets (mediators) including diabetes self-efficacy and self-care behaviors. 2. For whom does the MOSAIC adaptive tailoring approach improve outcomes more than the print materials alone? This aim examines how well the tailoring rules used for the MOSAIC intervention worked for different participants on the outcomes examined in the first aim. Participants will enroll in a 16-month study with assessments every 4 months. Assessments include completion of an A1c test and a survey. For those assigned to MOSAIC, they will experience 12-months of mobile phone-delivered support with 3 opportunities for intervention tailoring.
