ACT Intervention for Type 2 Diabetes Management for Rural and Underserved Community

Not Applicable

Recruiting

• Conditions: Type 2 Diabetes

• Registration Number: NCT06028503
• Lead Sponsor: Sam Houston State University

Brief Summary

The purpose of this project is to examine the feasibility/acceptability of a one-day Acceptance and Commitment Therapy + Lifestyle Education group intervention paired with 12-weeks of Continuous Glucose Monitoring for patients with type 2 diabetes (T2D) living in rural communities. This study is being designed as a randomized control trial (RCT) comparing ACT+LE+CGM to LE+CGM to LE. The ultimate goal of this line of research is that a community-wide intervention of Acceptance and Commitment Therapy (ACT) with Continuous Glucose Monitoring (CGM) and Lifestyle Education (LE) will improve T2D outcomes in rural communities compared to CGM and LE, or LE alone. Our goal is to develop a scalable and sustainable program for diabetes management in rural areas that enables individual self-management and does not require extensive healthcare resources in an existing medical desert.

Detailed Description

ADA guidelines highlight the essential role of nutrition therapy and/or diabetes self-management education (DSME) programs in diabetes management. A recent NHANES analysis which included 2365 people with diabetes indicated that only 32% are considered in good control of diabetes (HbA1c 6.5-6.9%). In the rural community at higher risk of diabetes, conventional lifestyle intervention approaches to diabetes management (e.g., Look AHEAD) or prevention, are not sustainable as they are resource intense. In medical deserts such as rural areas, there is a need for alternative strategies. To add, a mechanism that can impact lack of behavioral adherence is experiential avoidance. Experiential avoidance describes avoiding or escaping behaviors that cause B. distress, anxiety, shame, guilt, pain, and others. Acceptance and Commitment Therapy (ACT) targets experiential avoidance, which many believe prevents engagement in health behavior change. ACT has demonstrated efficacy in numerous psychological and biomedical diseases, including depression and anxiety, migraines, chronic pain, inflammatory bowel disease, weight loss, and T2D. ACT helps patients to overcome avoidance of health behaviors by promoting acceptance of negative feelings and thoughts and by encouraging them to engage in behaviors that align well with their values. Although dietary data suggest people with diabetes may be making self-perceived positive dietary changes, experiential avoidance likely prohibits sustained food behavior change and better self-management.

The purpose of this project is to examine the feasibility/acceptability of a one-day Acceptance and Commitment Therapy + Lifestyle Education group intervention paired with 12-weeks of Continuous Glucose Monitoring for patients with type 2 diabetes (T2D) living in rural communities. This study is being designed as a randomized control trial (RCT) comparing ACT+LE+CGM to LE+CGM to LE. The ultimate goal of this line of research is that a community-wide intervention of Acceptance and Commitment Therapy (ACT) with Continuous Glucose Monitoring (CGM) and Lifestyle Education (LE) will improve T2D outcomes in rural communities compared to CGM and LE, or LE alone. Our goal is to develop a scalable and sustainable program for diabetes management in rural areas that enables individual self-management and does not require extensive healthcare resources in an existing medical desert.

Specific aims:

Aim 1: To implement and adapt (to include CGM monitoring) an abbreviated (one day session) ACT protocol for T2D8 that we can administer at the group level to rural individuals. By the end of the one-day workshop, participants should understand how to use acceptance skills (e.g., mindfulness, cognitive defusion from negative thoughts) to engage in committed action towards T2D management and adherence. Two clinical psychologists, with input from the multidisciplinary team, will adapt the protocol and participant worksheets from existing brief ACT interventions for T2D.

Aim 2: To conduct a pilot single-blind randomized control trial of an adapted ACT for T2D, in combination with CGM and LE, to evaluate the feasibility, acceptability and initial efficacy of this protocol at a among in rural individuals. Therefore, this study will compare the efficacy of ACT+CGM+LE to CGM+LE, or LE alone, on hemoglobin HbA1c in 60 people with T2D recruited from a rural population.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: FACTORIAL

Primary Outcome Measures

Name	Time	Method
Reduction in Hemoglobin A1C	1-year	Our goal is to determine if CGM and ACT can change HbA1c 3 months after the intervention and to determine if those reductions can be sustained one year after the intervention.

Secondary Outcome Measures

Name	Time	Method
Body Composition	1-Year	Waist circumference will be measured at a level midway between the lower rib margin and iliac crest with the tape all around the body in a horizontal position, using a calibrated measuring tape.
Adherence	1-Year	We will administer the Diabetes Care Profile (DCP), which will assess our participants' frequency and adherence to regular blood sugar monitoring and their understanding of T2D.
Experiential Avoidance	1-Year	We will assess experiential avoidance with the Acceptance and Action Questionnaire - 2 (AAQ-2) - The AAQ-2 is a reliable and valid self-report measure of psychological flexibility and experiential avoidance.
Depression	1-Year	We will assess depression via the NIH Patient Report Outcomes Measures Information System (PROMIS) scale for depression. The NIH PROMIS measure for depression has eight items that reliably and validly assess the construct of depression.
Health literacy	Baseline	Health literacy will be measured using the Short Assessment of Health Literacy-English (SAHL-E) from the PhenX Toolkit. This includes 18 interviewer-administered items designed to assess the participants ability to read and understand common medical terms. This survey will be administered at baseline.
Body Mass Index	1-year	Body weight will be measured with the participant in light clothing without shoes. Body height will be measured to the nearest 0.1 cm without shoes using a calibrated stadiometer at screening only. Body weight and height will be used to calculate BMI (BMI = weight/height2 (kg/m2).
Food Insecurity	1-Year	Food insecurity will be assessed using the USDA Economic Research Services U.S. Adult Food Security Survey Module. This validated survey tool has 10 items in a three-stage design with screeners. Screening keeps respondent burden to the minimum, which improves data reliability. This will allow us to explore if food insecurity impacts diabetes progression.
