The initial assessment will take place at the time of study enrollment (T1). Participants will be offered a choice of assignment to either the eDTU (online Diabetes Tune-Up Group intervention participation) or iDTU (in-person Diabetes Tune-Up Group intervention participation) series. After a 3-month waiting period, participants will complete baseline assessment (T2). The group intervention will then take place over the next 6 to 8 weeks. Immediately following completion of the intervention, participants will complete surveys (T3). A final assessment will be completed 3 months after baseline, approximately 4 to 6 weeks following the completion of the intervention (T4).

The participant will participate in one series of the DTU intervention either, in person or online, at the participant's choosing. The intervention will take place over the course of 6 to 8 weeks. Participants will wear their continuous glucose monitor throughout the course of the intervention.

The eDTU and iDTU interventions will consist of 6 weekly group sessions lasting 90 minutes per session offered over a 6-8 week period. Each series will be co-facilitated by one diabetes care and education specialist and one behavioral health interventionist. Enrollment in each series will consist of 4-10 patients per group. The intervention components integrate key strategies that have been demonstrated to be effective in previous studies: motivational interviewing and introduction to stages of change; diabetes education; cognitive behavioral therapy with a particular emphasis on identification of cognitive distortions, thought stopping and cognitive reframing; emotional regulation; social support and miscarried helping; and behavioral strategies to support diabetes self-management. Each session will involve a psychoeducational portion, group discussion, and take-home assignments to be completed between sessions.

Change in DDS-17 scores over time; scores range from 1 - 6 with higher scores indicating worse diabetes distress

Change in A1c values over time

Acceptability of electronic DTU intervention (eDTU) adapted for cultural relevance and online delivery compared to waitlist control and the in-person DTU (iDTU) using study-developed satisfaction questionnaire; scores can range from 15 - 75 with higher scores indicating greater participant satisfaction

Feasibility of electronic DTU intervention (eDTU) adapted for online delivery compared to the in-person DTU (iDTU) using participant attendance to intervention sessions; attendance will range from 1 to 6 sessions

Evaluate changes in depressive symptoms in intervention (baseline to 3-month follow-up) compared to waitlist control (enrollment to baseline). An exploratory aim will be to compare changes in eDTU to the iDTU pre/post intervention (baseline & three-month follow-up); scores range from 0 - 27 with higher scores indicating more severe depression symptoms
