MyDiaText Text Messaging Intervention for Diabetes

Study Overview
=================
Brief Summary
-----------------
To test a text messaging intervention using MyDiaText and financial incentives to determine whether such an intervention will improve self-reported self-care behaviors in children 12 to 18 years old. The intervention will consist of daily text messages sent to the subject's personal mobile device. Subjects will be incentivized to respond to text messages via a lottery financial incentive. Previously developed text messages based on the American Diabetes Association (ADA) behavior goals will be used for this intervention.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention<br>This group will receive the intervention for 6 months. The intervention will consist of daily text messages sent to the subject's personal mobile device in addition to the usual standard care. Subjects will be incentivized to respond to text messages via a financial reward lottery system. Previously developed text messages based on the ADA behavior goals will be used for this intervention. | Other: MyDiaText<br>* The intervention will consist of daily text messages sent to the subject's personal mobile device.<br>|
| No Intervention: Control<br>This group will receive the usual standard of care for 6 months. | |

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Self-Care Inventory (SCI) Score From Baseline to 6 Months | Estimate of self-management will be assessed via the Self-Care Inventory questionnaire. This scale measures self-reported adherence to diabetes self-care behaviors. A higher score on 1-5 scale is associated with more self care behaviors, i.e., better outcomes. The outcome was mean score on the scale. If a participant responded N/A, this question was not included in calculation of mean score. | 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Hemoglobin A1c (HbA1c) From Baseline to 6 Months | Hemoglobin A1c is a measure of glycemic control scale that reflects how well they followed recommendations for self-care during the past month (1=never do it to 5 =always do this as recommended, without fail). Total scores range from 1-70 and previous data shows that youth with better self-care levels (higher scores) have significantly better glycemic control. | 6 months |
