To explore the feasibility of a culturally-tailored, mobile (mHealth) intervention for Chinese immigrant patients with type 2 diabetes (T2D), investigators enrolled patients (n=23) and their local family members or friends (n=23) into a randomized controlled trial. Eligible participants met the following inclusion criteria:

• Self-identified as Chinese immigrant or Chinese American
• Between 18–70 years old at enrollment
• Able to speak and understand Mandarin
• Currently using WeChat or text messages
• Willing to receive WeChat or text messages regarding T2D management
• Expressed strong interest and confidence in finishing 2 diabetes videos each week for a total of 12 weeks.

Participating dyads were randomized into the FAMILY intervention group (n = 11) or the wait-list control group (n = 12). The FAMILY intervention was adapted from a previously tested CARE intervention, which did not include family and friends. FAMILY is a 12-week intervention which offers diabetes self-management education (DSME) through brief 50-10 minute videos that can be accessed at any time. Participants and their families/friends in the FAMILY intervention group received the same 2 videos every week for 12 weeks through WeChat. Topics included T2D, diabetes self-management at home, behavioral techniques, and family-oriented sessions. Reminders were sent to participants who missed three consecutive videos. The primary outcomes assessed were feasibility and acceptability, which were measured by the retention rate, video watch rate, and a satisfaction survey. Secondary outcomes included patients’ HbA1c, self-reported weight, and self-management behaviors measured through a number of questionnaires. Secondary outcomes were measured at baseline, 3-months, and 6-months.
