iOmit: Reducing Intentional Insulin Misuse in Type 1 Diabetes (iOmit)
Individuals with type 1 diabetes who intentionally omit insulin to lose weight are at high risk for diabetes-related medical complications and premature death. Conventional eating disorder (ED) treatments are not as effective for these patients, suggesting that they need a more tailored treatment approach and one that includes intervention at the time and place when they are making decisions about their diabetes self-management. The goal of treatment development project is to modify an existing mobile application (app) for EDs (Recovery Record; RR) to address the unique needs of adults with type 1 diabetes (T1D) who intentionally omit their insulin for weight control, and test whether app-supported individual treatment decreases eating disorder (ED) symptoms and improves metabolic control. The investigator will also gather preliminary data on the impact of the intervention on health care utilization and costs and calculate attrition to assess feasibility.
The investigators hypothesize that (1) participants will evidence significant decreases in mean blood glucose, (2) participation in routine medical care will increase and emergency visits will decrease, (3) the percentage of time participants are hyperglycemic will decrease, (4) participant scores on the DEPS-R will decrease and (5) participant scores on the EDE will decrease.

Sperimentale: Therapy with Mobile App Enhancement
Participants will complete initial assessments and then take part in a 3-month intervention consisting of 12 weekly individual therapy sessions with daily RR app use between sessions.
At the end of the 3-month intervention period, an exit interview will be conducted and participants will complete a second assessment consisting of questionnaires and an ED diagnostic interview, a blood specimen for HbA1c, and 3-days of blinded CGM monitoring.
Participants will then enter a 6-month follow-up period during which time they may continue to use the app, but will no longer attend individual sessions.
Participants will be return to the clinic at 6 and 9 months for follow-up.
|
Treatment includes 12 weekly therapy sessions with daily RR app use between sessions.
Intervention is CBT-based and specifically draws from ACT. ACT is a contextual behavior therapy that emphasizes the function of behavior (e.g., affect regulation) and helps individuals accept (or "tolerate") emotional discomfort for a broader purpose (i.e., personal values).
Broadly, treatment will focus on improving diabetes management by increasing patients' capacity to effectively cope with psychological barriers to self-care using acceptance and mindfulness strategies.
