Detailed Description
Evaluation of a Complex Behavioral Intervention for Young Adults with Diabetes: The Resilient, Empowered, Active Living-Telehealth (REAL-T) Study will address the unmet self-management and psychosocial needs of young adults (YAs) with type 1 diabetes (T1D).
We will conduct a large-scale randomized controlled trial (n=210) to compare the 6-month REAL-T intervention to usual care in improving glycemic control (A1c and continuous glucose monitor-derived measures), psychosocial well-being, and hypothesized intervention mediators. In addition, we will perform health economic analyses to determine the extent to which REAL-T is cost-effective or produces cost savings.
The study's specific aims are as follows:
Aim 1: Evaluate the efficacy of REAL-T in improving glycemic control and psychosocial well-being.
- Hypothesis 1: Over a 6-month intervention period (including 3 and 6 month measures), YAs with T1D who receive REAL-T demonstrate improvements in glycemic control, in comparison to YAs with T1D who receive usual care.
- Hypothesis 2: Over a 6-month period (including 3 and 6 month measures), YAs with T1D who receive REAL-T demonstrate gains in psychosocial well-being in comparison to YAs with T1D who receive usual care.
Aim 2: Assess the post-intervention durability (at 3 and 6 months post-intervention) of REAL-T's effects on glycemic control and psychosocial well-being.
- Hypothesis 1: Among YAs with T1D, improvements in glycemic control that result from REAL-T relative to usual care are maintained at 3 and 6 months post-treatment.
- Hypothesis 2: Among YAs with T1D, improvements in psychosocial well-being that result from REAL-T relative to usual care are maintained at 3 and 6 months post-treatment.
Aim 3: Examine mediating mechanisms of the REAL-T intervention's effects on glycemic control and psychosocial well-being through structural equation modeling (SEM).
- Hypothesis 1: Improvements in diabetes self-care behaviors mediate positive intervention effects on glycemic control and psychosocial well-being.
- Hypothesis 2: Improvements in self-efficacy mediate positive intervention effects on psychosocial well-being and partially mediate positive effects on diabetes self-care behaviors.
- Hypothesis 3: Improvements in habit strength for diabetes self-care behaviors partially mediate positive intervention effects on the performance of diabetes self-care behaviors.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in glycemic control, using Glycated Hemoglobin (HbA1C)
Time Frame: Baseline, 3 months, 6 months, 9 months, and 12 months
|
HbA1C is a measure of average blood glucose concentration over approximately the previous 12 weeks.
HbA1C will be measured using a finger-prick test and DCA Vantage Analyzer point-of-care system.
|
Baseline, 3 months, 6 months, 9 months, and 12 months

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in diabetes-related quality of life, using the "Audit of Diabetes-Dependent Quality of Life-15" (ADD-QoL-15)
Time Frame: Baseline, 6 months, and 12 months
|
15-item questionnaire assessing diabetes-related quality of life (qol).
Each item contains two parts.
Part A is: "If I did not have diabetes, [the question topic] would be", followed by 5 options ranging from "very much better" (or similar; scored as -3) to "worse" (or similar; scored as 1).
The fourth option is always "the same" and scored as 0. Part B is: "[the question topic] is" followed by 4 options ranging from "very important" (scored as 3) to "not at all important" (scored as 0).
For each question, scores on parts A and B are multiplied, and the 15 products are summed for a total score.
Questions 2, 4, 6, 8, 9, & 11 have preliminary yes/no questions, and when a "no" response is given, parts A and B are skipped and the score for that question is 0. The minimum score on each question is -9 and the maximum is 3, with total scores ranging from -135 to 45. Positive scores reflect perceived positive impact of diabetes on qol; negative scores reflect perceived negative impact on qol.
|
Baseline, 6 months, and 12 months
|
Change in diabetes-related emotional distress, using the "Diabetes Distress Scale" (DDS)
Time Frame: Baseline, 6 months, and 12 months
|
17-item questionnaire assessing diabetes-related emotional distress.
Total scores (mean score on all 17 items) range from 1 to 6. Sub-scale scores (emotional burden, physician-related distress, regimen-related distress, and interpersonal distress) each range from 1 to 6.
A total or sub-scale score 2.0 - 2.9 should be considered 'moderate distress,' and a total or sub-scale score > 3.0 should be considered 'high distress.'
|
Baseline, 6 months, and 12 months
|
Change in functional health and well-being, using the "SF-12v2® Health Survey"
Time Frame: Baseline, 6 months, and 12 months
|
Short Form 12-item Health Survey Ver. 2 (SF-12v2) is a 12-item questionnaire assessing functional health & well-being over the last 4 weeks in 8 health domains (physical functioning, role participation with physical health problems, bodily pain, general health, vitality, social functioning, role participation with emotional health problems, mental health), all from the patient's point of view.
These 8 domains can be summarized into a physical component summary (PCS) and a mental component summary (MCS).
Higher scores indicate a better health state.
MCS and PCS scores range from 0-100.
Scores are calibrated using general population-derived normative data so that 50 is the avg score or norm.
Results can be further summarized into a single preference-based health utility number ranging from 1 (equivalent to perfect health) to 0 (equivalent to being dead), using a complex scoring algorithm (SF-6D) derived from surveying a general U.S. population's preferences for specific health states.
|
Baseline, 6 months, and 12 months
|

Time Frame: Baseline, 3 months, 6 months, 9 months, and 12 months
|
27-item questionnaire assessing self-care activities associated with glycemic control.
Higher values indicate more effective self-management.
Transformed scores = Actual sum of items / maximum possible sum of items x 10.
Total transformed scores range from 0 to 10. Transformed scores on six sub-scales (Dietary control, Glucose management, Glucose monitoring, Medication adherence, Physical activity, and Physician contact) also range from 0 to 10.
|
Baseline, 3 months, 6 months, 9 months, and 12 months
|
Change in medication adherence, using the "3-item adherence self-report scale" questionnaire
Time Frame: Baseline, 3 months, 6 months, 9 months, and 12 months
|
3-item questionnaire (Wilson,Lee, Fowler, & Rogers, 2016) assessing adherence to diabetes medication regimen.
Item responses for the three adherence items are linearly transformed to a 0-100 scale with zero being the worst adherence, and 100 the best.
A total summary score is calculated as the mean of the three individual items, with a range of 0 to 100.
|
Baseline, 3 months, 6 months, 9 months, and 12 months
|
Change in automaticity of behavior (testing blood sugar), using the "Self-Report Behavioural Automaticity Index" (SRBAI)
Time Frame: Baseline, 3 months, 6 months, 9 months, and 12 months
|
4-item questionnaire assessing habit strength for testing blood sugar, using 7-point likert scales.
Scores range from 4 to 28.
A higher score indicates greater automaticity.
|
Baseline, 3 months, 6 months, 9 months, and 12 months
|
Change in self-efficacy for performing diabetes self-management, using the "Diabetes Empowerment Scale - Short Form" (DES-SF)
Time Frame: Baseline, 3 months, 6 months, 9 months, and 12 months
|
8-item questionnaire assessing self-efficacy for performing diabetes self-management, using 5-point likert scales.
The scale is scored by averaging the scores of all completed items.
Scores range from 8 to 40, with higher scores indicating higher self-efficacy.
|
Baseline, 3 months, 6 months, 9 months, and 12 months
|
Change in autonomy of taking insulin and/or checking blood sugar, using the "Treatment Self-Regulation Questionnaire" (TSRQ)
Time Frame: Baseline, 3 months, 6 months, 9 months, and 12 months
|
19-item questionnaire, adapted for type 1 diabetes, assessing the degree to which a person's motivation for a particular behavior or a set of behaviors is relatively autonomous or self-determined.
Each item can receive a value ranging from 1 - 7 as selected by the participant.
The scale has 2 sub-scales: the autonomous regulatory style and the controlled regulatory style.
Calculating the scores for the sub-scales consists of averaging the items on that sub-scale.
A Relative Autonomous Motivation Index can be formed by subtracting the average for the controlled reasons from the average for the autonomous reasons.
Scores range from 1 to 7, with 7 indicating a strong identification with the given autonomy style.
The autonomous regulatory style represents the most self-determined form of motivation.
