Development of a Web-Based Diabetes Prevention Program (DPP) for Chinese Americans: A Formative Evaluation Approach

Area of Science:

• Public Health
• Digital Health
• Health Disparities

Background:

• Type 2 diabetes prevention is crucial, with online programs showing promise.
• Chinese Americans with prediabetes are an underserved population for type 2 diabetes prevention.
• Culturally and linguistically tailored interventions are needed to address health disparities.

Approach:

• Community-Based Participatory Research (CBPR) and Intervention Mapping were utilized.
• A mixed-methods approach, including literature review, focus groups, and a community advisory board, informed program development.
• Formative research engaged community members to ensure cultural relevance and address potential barriers.

Key Points:

• Online Diabetes Prevention Programs (DPPs) are perceived as useful and accessible by Chinese Americans.
• Barriers such as low computer literacy and technology self-efficacy were identified.
• Meal photo tracking and pedometer use were acceptable self-monitoring tools.
• Text message reminders and social support groups were proposed to enhance engagement and reduce attrition.

Conclusions:

• Culturally and linguistically appropriate online DPPs can be developed using CBPR principles.
• Addressing identified barriers is essential for successful implementation of digital health interventions.
• This theory-based, culturally tailored online DPP warrants further testing in intervention studies.
