Project Dulce for Arab Americans With Type 2 Diabetes
What this study is about
Arab Americans (AA) face many challenges in diabetes self-management due to the limited educational resources and support available for them. The cultural and linguistic barriers between patients and health care providers lead to poor diabetes management and outcomes.
View original scientific description
Arab Americans (AA) face many challenges in diabetes self-management due to the limited educational resources and support available for them. The cultural and linguistic barriers between patients and health care providers lead to poor diabetes management and outcomes. This study (Project Dulce Arabic) is adapted from the Project Dulce, an American Diabetes Association (ADA)-recognized Diabetes Self-Management Education Support (DSMES) program. Project Dulce Arabic comprises both peer-led diabetes education in Arabic and a 3-month text messaging program (Dulce Digital). The main aim of the study is to examine the effectiveness of a more culturally and linguistically appropriate diabetes education program in improving diabetes knowledge, beliefs, and self-management as well as hemoglobin A1C.
Interventions
BEHAVIORAL
Project Dulce + Dulce Digital
Project Dulce is a 5-week curriculum, group diabetes self-management education and support, program delivered by a peer educator in Arabic. The curriculum provides knowledge as well as skills and tools needed to change behaviors and adapt to a life with type 2 diabetes. The curriculum covers diabetes and its complication, the role of diet, exercise, and medication, and the importance of self-monitoring as well as the genetics contribution to diabetes development. It is presented over 5 weeks where participants will learn and practice diabetes self-management skills, and help one another address family, cultural, or health system barriers to managing their diabetes. . Following the 5-week curriculum, participants will be enrolled in the digital texting platform, Dulce Digital, in which they will receive on-going support via text messages derived from the curriculum, medication reminders, and blood glucose monitoring prompts in Arabic.
Primary outcome measures
Change from Baseline Diabetes Knowledge at 3 months
Time frame: 3 months
Diabetes Knowledge Test (Diabetes Research and Training Center, University of Michigan, 2015) is a 23-item measure of diabetes knowledge, with general questions related to symptoms, self-management (e.g., diet, exercise, foot care, blood glucose monitoring, insulin), and complications (e.g., low, and high blood sugar). Greater scores indicate greater diabetes knowledge.
Change from Baseline Diabetes Knowledge at 6 months
Time frame: 6 months
Diabetes Knowledge Test (Diabetes Research and Training Center, University of Michigan, 2015) is a 23-item measure of diabetes knowledge, with general questions related to symptoms, self-management (e.g., diet, exercise, foot care, blood glucose monitoring, insulin), and complications (e.g., low, and high blood sugar). Greater scores indicate greater diabetes knowledge.
Change from Baseline Health Belief Model Scale at 3 months
Time frame: 3 months
Health Belief Model scale (Tan, 2004) is comprised of 36 items that evaluate the health beliefs and attitudes about complications prevention behaviors and active health related behaviors in individuals with diabetes. Responses are on a 5-point Likert-type scale (1=strongly disagree, 5=strongly agree), with lower scores indicating greater negative beliefs.

Change in Baseline Self-Efficacy for Diabetes Scale at 3 months
Time frame: 3 months
Stanford Self-Efficacy for Diabetes Scale (Lorig, Stewart, Ritter, et al., 1996) is comprised of 8 items that measure the confidence of a participant in performing self-care activities such as eating meals every 4 to 5 hours, following a healthful diet, exercising, and blood glucose monitoring. Response options range from 1=not at all confident to 10=totally confident, with higher scores indicating greater self-efficacy.

Understanding Health Implications of Genomics at 3 months
Time frame: 3 months
To assess the genetic knowledge, a 12-items questionnaire. Response options are 'agree', 'disagree', or 'don't know'. Similarly, a 13-items questionnaire with response options of 'agree' or 'disagree' will be used to assess the attitudes toward genetics research and testing.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
