Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall goal of this randomized clinical trial (RCT) is to test the efficacy of a culturally- and literacy-tailored cognitive-behavioral intervention designed to enhance adherence to diabetes self-management behaviors and improve glycemic control among low-income Hispanic individuals with type 2 diabetes mellitus.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients are randomly assigned to a Usual Care condition or to the Cognitive Behavioral Intervention condition. The unit of randomization and analysis is the patient. The intervention is implemented by a nutritionist, a nurse diabetes educator and an assistant, and patients are encouraged to bring a family member or friend living in the same household to facilitate home-based support for the intervention. The intervention emphasizes patients' ethnic preferences and traditions (e.g., adapting ethnic recipes to meet dietary goals) and the use of available community resources (e.g., available areas for exercise), and is delivered utilizing strategies and materials appropriate for low-literate/illiterate pts.
