Brief Summary
The study will test an app and web-delivered intervention designed to improve glycemic control (HbA1c) among young adults with Type 1 diabetes. All participants will receive the "core" digital intervention, the SweetGoals app, focused on self-monitoring and goal setting. Efficacy of two independent intervention components (incentives for adherence and web health coaching) will be tested

Eligibility Criteria
You may qualify if:
- Have a diagnosis of T1D for \>18 months
- Have A1c ≥7.5%
- Report a visit with physician managing type 1 diabetes (T1D) within the previous 6 months
- Participants must use a glucometer or continuous glucose monitor compatible with Glooko.
You may not qualify if:
- Pregnancy or breast feeding
- Severe medical illness that would preclude participation (e.g., cystic fibrosis, developmental disability, severe cognitive impairment)
- Psychiatric illness that would preclude participation
- Diabetes diagnoses other than T1D (Type 2 Diabetes, Maturity Onset Diabetes of the Young/MODY)
- Use of any medications known to impact glycemic control (oral or injectable corticosteroids, beta-blockers, antipsychotic medications such as risperidone).
- A history of known hemoglobinopathy, anemia, or transfusion (which could alter the validity of HbA1c measurement)
- Already being engaged in a psychological intervention targeting diabetes adherence.

- STUDY PROTOCOL
- Time Frame
- If the study ends and data are no longer being obtained directly from study participants by study investigators, all study data will be provided to the Repository by the end of the funding period (which may include no-cost extensions). The period of exclusive use of the entire dataset from the study will be for three years after the last study contact for collection of intervention outcomes.
- Access Criteria
- Data requests made directly to the Principal Investigator or through the NIDDK Data Repository
Data will be made available to other researchers and practitioners, while safeguarding the privacy of participants and protecting confidential and proprietary data and third-party intellectual property. Findings will be published as soon as they are available in relevant peer-reviewed journals that are available online, and share as requested directly to the author(s).
