FAMS-T1D Self-Regulation and Social Support for T1D

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical trial is to evaluate how effective the FAMS-T1D intervention is for improving self-regulation (e.g., setting and meeting goals for type 1 diabetes) and social support for meeting those goals for young adults. The main questions that are examined include 1) whether the intervention improves blood glucose, self-management and diabetes distress across time, 2) whether these improvements occur through better self-regulation and social-regulation, 3) whether the intervention improves outcomes for support persons (a friend or family member invited to participate by the person with diabetes) without increasing support burden and 4) whether the intervention improves for persons with diabetes who are on continuous blood glucose monitor their time in range.

Detailed Description
-----------------
This 12-month intervention is an adaptation and expansion of an intervention originally developed for adults with type 2 diabetes (FAMS; NCT02481596) for young adults with type 1 diabetes. FAMS-T1D includes multiple components: Monthly coaching sessions (20-30 minutes each) with young adults with type 1 diabetes by phone. The coaching focuses on how to set specific and achievable diabetes goals and to increase helpful and decrease unhelpful family and friend behaviors related to those goals. Daily text messages to the person with diabetes to support meeting diabetes goals and engage support that is helpful in meeting those goals. Weekly text messages where the person with diabetes responds to how well they have met their goals followed by personalized feedback from the coach. The option to invite an adult support person to also receive text messages that assist the support person in providing support that assists the person with diabetes in meeting their goals set in the coaching sessions. Participants will be randomized to either the intervention or an active control where individuals receive materials relevant to their type 1 diabetes. We plan to enroll 280 persons with diabetes and support persons (optional for persons with diabetes). Persons with type 1 diabetes and their support person (when enrolled) will be randomized together. The study is powered to detect a .5% reduction in hemoglobin A1c. Analyses will examine effects at 6 months (post intervention) and at 12 months (maintenance of effects). The investigators will impute missing data and individuals will be analyzed as randomized irrespective of whether they withdraw or remain in the study following intention-to-treat principals.

| --- | --- |
| Experimental: FAMS-T1D<br>Participants will receive FAMS-T1D components (monthly phone coaching and text message support for goals) for 6 months. Support person will receive text messages that are tailored to the goal set by the person with type 1 diabetes. All persons with diabetes will receive text messages regarding how to access their HbA1c results and receive links providing information to assist them in self-care behaviors related to their diabetes. All support persons will also receive materials about type 1 diabetes and how to provide helpful support to the person with diabetes. | Behavioral: FAMS-T1D<br>* Behavioral FAMS-T1D FAMS-T1D involves monthly phone coaching that assists individuals in setting specific and time bound diabetes goals with automated text message support to the patient participant and less frequent automated text messages to their support person, if one is enrolled.<br>* Other names: Family/friend Activation to Motivate Self-Care for those with Type 1 Diabetes;Behavioral: Digital resources for diabetes<br>* Behavioral: Diabetes Resources High quality digital materials about diabetes management will be provided upon enrollment and send to participants quarterly.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in HbA1c (Person with Diabetes) | Higher values indicate values more off target. Hemoglobin A1C assessed by mail-in kits from University of Minnesota ARDL | Baseline and 6, 9, and 12 months post baseline | 
| Change in Self-Management (Person with Diabetes) | Self-care inventory revised, higher values indicate better self-management (values range from 1 to 5) | Baseline and 6, 9, and 12 months post baseline | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diabetes Distress (Person with Diabetes) | The Diabetes Distress Scale for Adults with Type 1 Diabetes, higher values indicate greater distress (values range from X to X) | Baseline and 6, 9, and 12 months post baseline |
