Fusing Rapid-cycle Testing and Adaptive Trial Designs: A Scientific Pipeline to Translate and Individualize Evidence-based Psychosocial and Behavioral Interventions in Routine Type 1 Diabetes Care
Fusing Rapid-cycle Testing and Adaptive Trial Designs: A Scientific Pipeline to Translate and Individualize Evidence-based Psychosocial and Behavioral Interventions in Routine Type 1 Diabetes Care
This study is designed to compare two behavioral approaches to reduce diabetes distress ("the expected burdens, concerns, fears, and threats that arise from the challenges of living with diabetes") in adults with type 1 diabetes. At the study baseline, participants will be randomized to take part in one of two virtual, group-based interventions (the "Primary" intervention) utilizing either an emotions-focused or a problem-solving approach to reduce diabetes distress. After the initial intervention, participants will complete surveys to assess their response to the material. Participants who are determined to be "non-responders" (i.e., the Primary intervention was not effective) will be re-randomized to one of two "Supplementary" interventions, which will include individualized sessions to learn and/or practice strategies related to either the psychological or problem-solving approach.
The study will compare the effectiveness of an emotions-focused approach with a problem-solving based approach to reduce diabetes distress (DD). The investigators will enroll N=200 adults 30 years and older with type 1 diabetes (T1D) and elevated DD from a single clinical site to participate in a 12-week study. All interventions and assessments will be delivered in a pragmatic and entirely virtual format. The investigators will utilize a precision medicine trial design (Sequential Multiple Assignment Randomized Trial; SMART) to compare two evidence-based, virtual group interventions to reduce DD in adults with T1D (primary aim). The secondary aims of the study are to estimate next best steps for participants who do not respond to group-based interventions, and to estimate optimal treatments or sequences of treatments for different individuals based on their individual characteristics, including response to prior treatment.
The study includes an initial randomization to one of two 5-week Primary Interventions: "ReCharge", an Acceptance and Commitment Therapy (ACT)-focused approach that will help to reduce the emotional burden of diabetes management; or "TakeCharge", a problem-solving focused approach that will equip participants with new skills to manage type 1 diabetes. Participants will complete a series of assessments to determine their response to the Primary Intervention. Participants who did not respond to the Primary Intervention will be re-randomized to participate in one of two Supplementary Interventions over a 5-week period, where they will have three virtual, individualized sessions for exposure and practice with either the ReCharge or TakeCharge curriculum.
The investigators will evaluate the Reach, Effectiveness, Adoption, Implementation, and Maintenance of all phases of the study. By collecting both quantitative data and key qualitative feedback from providers and participants, the investigators will be able to assess and improve the pragmatic design of these evidence-based interventions for routine integration into healthcare settings. Completion of primary and secondary aims will inform a future program which saves resources and expands the availability of guidelines-oriented care to all patients with T1D.
