Study Description

Brief Summary:

This research will compare a psychological intervention ("ACT1VATE") versus diabetes self-management education and support (DSME/S; usual care) in improving clinical, behavioral, psychosocial, process, and cost outcomes among adults with poorly controlled type 1 diabetes (T1D) who are experiencing significant diabetes-related emotional distress and poor glycemic control in a real world, healthcare environment.

Condition or disease	Intervention/treatment	Phase
Type 1 Diabetes	Behavioral: ACT1VATE; Behavioral: DSME/S	Phase 2

Detailed Description:

This randomized controlled trial will compare a telemedicine psychological intervention specifically designed to address diabetes distress ("ACT1VATE") versus traditional diabetes self-management education and support (DSME/S; usual care) in improving glycemic control among N=250 adults with type 1 diabetes (T1D), glycosylated hemoglobin (HbA1c) between 7.5% - 12.5% in the last 90 days, and significant diabetes distress. Capitalizing on existing and real-world processes, the electronic health record (EHR) will be used to identify eligible patients and examine primary outcomes. Participants randomized to the usual care group will be offered standard, 1:1 DSME/S delivered by a Certified Diabetes Care and Education Specialist via telemedicine format. Participants randomized to the ACT1VATE group will be offered 5 group-therapy telemedicine sessions delivered by a Behavioral Health Provider who is an integrated member of the diabetes care team. ACT1VATE is grounded in Acceptance and Commitment Therapy (ACT), which has been delivered effectively in clinics via brief format; implemented via phone and other modalities; and adapted for a wide range of chronic conditions. The primary clinical outcome, HbA1c, assessed as part of quarterly standard-of-care medical visits will be extracted from the EHR over 12 months. Changes in patient-reported behavioral (diabetes self-care) and psychosocial (emotional well-being, quality of life) outcomes will be evaluated via online surveys at baseline, month 6, and month 12. A thorough process evaluation will be conducted to establish reach, acceptability/feasibility, adoption/maintenance, and fidelity of the intervention and will integrate patient and provider perspectives. Cost-effectiveness will also be examined from the health system perspective. By maximizing integration with routine medical care for T1D in a real world, healthcare environment, results will be highly generalizable and hold great potential to inform the future of care for adults living with T1D.

Other Outcome Measures:

1. Cost-effectiveness [ Time Frame: 12 months ]
   Long-term cost-effectiveness of ACT1VATE will use a simulation model. The UKPDS Outcomes Model Risk Engine (UKPDS-OM) developed the predictive equations for diabetes-related complications, mortality, and assigned utilities conditional on disease. Estimated clinical effects + costs of each arm will be inputs into the UKPDS-OM model. Estimated clinical effects (HbA1c change) come from Aim 1. Intervention costs will be estimated using standard accounting methods, process mapping + time-based activity costing. Base case assumes a health system perspective, 40-year time horizon, and 3% discount rate for both QALY and costs. Sensitivity analyses will investigate the influence of the estimated treatment effects and intervention costs, the influence of time horizon and discount rate, and second order uncertainty. UKPDS-OM provides equation parameters derived from bootstrap samples of the original UKPDS population. Estimates will be used to calculate an incremental cost-effectiveness plan.
2. Diabetes-Specific Self Compassion Scale [ Time Frame: Baseline, 6 months, 12 months ]
   Diabetes-Specific Self-Compassion Scale (D-SCS; range 0-5 with higher scores indicating higher levels of diabetes-specific self-compassion) will be analyzed to evaluate theoretical fidelity.
