Brief Summary

This study is designed to test the feasibility and acceptability of 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. This is a pilot study, which will enroll a small group of participants to enroll and give feedback on their experience.

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 intervention, participants will attend focus groups and fill out anonymous qualitative surveys to give feedback on their experience. Results of the pilot will inform and improve an upcoming research study of the same design.

Detailed Description

The study will test the feasibility and acceptability of two behavioral-based interventions to reduce diabetes distress (DD). The investigators will enroll one cohort (N=15) adults 30 years and older with type 1 diabetes (T1D) and elevated DD from a single clinical site to participate in a 5-week intervention. All interventions and assessments will be delivered in a pragmatic and entirely virtual format.

The investigators will compare two evidence-based, virtual group interventions to reduce DD in adults with T1D. The study includes a 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.

After the 5-week intervention period, participants will provide final outcome data and feedback on their experience using surveys and focus groups. Quantitative and quantitative results will be used to improve the intervention prior to rollout of a longer-term trial of the same design. Long-term data will be collected at 12-weeks post enrollment.

Primary Outcome Measures

Name	Time	Method
Change in Total Diabetes Distress (T1-DDS Total Score)	Baseline, Endpoint (6 weeks)	Self-reported total diabetes distress will be measured using the 28-item Type 1 Diabetes Distress Scale (T1-DDS Total Score). The scale yields an overall distress score that is the average of all responses rated on a 6-point Likert scale for all 28 items (range 1-6). A score \>= 2.0 is considered clinically significant diabetes distress. The primary efficacy outcomes of this study is the change in the T1D-DDS score and the proportion of individuals with a change in the T1D-DDS score at least as large as one minimally clinically important difference (MCID).

Secondary Outcome Measures

Name	Time	Method
Change in Core Diabetes Distress (T1-DDAS Core Score)	Baseline, Endpoint (6 weeks)	Self-reported core diabetes distress will be measured using the newer, 8-item Type 1 Diabetes Distress Assessment System (T1-DDAS Core Score). The scale yields a core distress score that is the average of all responses rated on a 5-point Likert scale for all 8 items (range 1-5). A score \>= 2.0 is considered clinically significant diabetes distress.
Change in Sources of Diabetes Distress (T1-DDS Subscale Scores)	Baseline, Endpoint (6 weeks)	Self-reported sources of diabetes distress will be measured using the 7 subscales of the 28-item Type 1 Diabetes Distress Scale (T1-DDS Subscale Scores). In addition to the Total Score, the T1-DDS scale also yields a score for each of 7 subscales based on the average response on all of the items in that subscale (range = 1-6). The 7 subscale scores measure sources including: Powerlessness, Management Distress, Hypoglycemia Distress, Negative Social Perceptions, Eating Distress, Physician Distress, and Friend/Family Distress. A score \>= 2.0 is considered clinically significant diabetes distress for each source.
Change in Perceived Stress	Baseline, Endpoint (6 weeks)	The Perceived Stress Scale 4 (PSS-4) is a 4-item questionnaire used to measure the degree to which situations in one's life are appraised as stressful during the last month. Respondents self-report the frequency of four key thoughts and feelings over the past month using a 5-point Likert scale. Total score is determined by adding together the scores of each of the four items (range 0-4).
Change in Diabetes Quality of Life	Baseline, Endpoint (6 weeks)	The Diabetes Quality of Life (DQOL) - Brief Clinical Inventory is a 15-item questionnaire used to provide a total health-related quality of life score that predicts self-reported diabetes care behaviors and satisfaction with diabetes control. Items are scored on 5-point Likert scale under two general formats. One format asks about the frequency of negative impact of diabetes itself or of the diabetes treatment and provides response options from 1 ("Never") to 5 ("All the time"). The second format asks about satisfaction with treatment and quality of life and is scored from 1 ("Very satisfied") to 5 ("Very dissatisfied").
Change in Perceived Confidence in Diabetes	Baseline, Endpoint (6 weeks)	The Perceived Competence in Diabetes Scale (PCDS) is a 4-item questionnaire used to assess the degree to which persons with diabetes feel they can manage the everyday aspects of diabetes care. Items are scored on a 1-7 Likert scale from 1 ("not at all true") to 7 ("very true"); items are averaged to form a perceived competence score (range 1-7).
Change in Diabetes Specific Self-Compassion	Baseline, Endpoint (6 weeks)	The Diabetes Specific Self-Compassion (SCS-D) is a 19-item questionnaire used to assess diabetes specific self-compassion and self-buffering against negative emotions in adults with T1D. Items are scored on a 1-5 Likert scale; average scores determined by calculating the mean of subscale item responses.
Change in Hypoglycemic Attitudes and Behaviors	Baseline, Endpoint (6 weeks)	The Hypoglycemic Attitudes and Behavior Scale (HABS) is a 14-item self-report scale highlighting two critical dimensions of hypoglycemia-related concerns (anxiety and avoidance) and one positive dimension (confidence). Items are scored on a 1-5 Likert scale from 1 ("Strongly Disagree") to 5 ("Strongly Agree"); Mean item scores are assessed for each hypoglycemia related dimension.
Change in Hemoglobin A1c (HbA1c)	Baseline, Endpoint (6 weeks)	HbA1c (%) reflects average glucose over the past 2-3 months. Value will be assessed by standardized laboratory assay for trial baseline and endpoint. 3- and 6-mo post-Endpoint data will be extracted from the electronic medical record.
Change in Percent of Time in Range (TIR)	Baseline, Endpoint (6 weeks)	For participants using personal continuous glucose monitors (CGM), the percentage of sensor values between 70-180 mg/dL will be measured using 7-14 days of retrospective data at each time-point. Change in TIR will be calculated across time-points.
Change in Percent of Time Below Range (TBR)	Baseline, Endpoint (6 weeks)	For participants using personal continuous glucose monitors (CGM), the percentage of sensor values in the hypoglycemic range (\<70 mg/dL) will be measured using 7-14 days of retrospective data at each time-point. Change in TBR will be calculated across time-points.
Change in Percent of Time Above Range (TAR)	Baseline, Endpoint (6 weeks)	For participants using personal continuous glucose monitors (CGM), the percentage of sensor values in the hyperglycemia range (\>180 mg/dL) will be measured using 7-14 days of retrospective data at each time-point. Change in TAR will be calculated across time-points.
Glycemic Variability	Baseline, Endpoint (6 weeks)	For participants using personal continuous glucose monitors (CGM), glycemic variability will be assessed using the coefficient of variation (%CV). Change in %CV will be calculated across time-points.
