Health Chat for Empowerment-based Lifestyle Planning for Cardiometabolic Multimorbidity

The intervention consists of two phases. Phase 1 is an initial individualized, face-to-face meeting to collaboratively set goals and develop action plan (week 1) and Phase 2 is an ongoing, personalized online support delivered by WeChat platform utilizing the official account, chat function, and synchronized online videos to integrate and sustain healthy lifestyle (weekly, week 2-12). Phase 1 covers 4 core steps: 1) assess symptom burden and lifestyle behaviors; 2) generate and analysis symptom burden and lifestyle report; 3) empowerment-based therapeutic person-centered health communication; and 4) behavior commitment. Phase 2 covers two modules: 1) integrate healthy behaviors to long-term lifestyle, and 2) sustain healthy lifestyle behaviors.

"Participants in this group will continue with their normal daily lifestyle. WeChat-based follow-up will be performed weekly in the first 4 weeks and bi-weekly in the next 8 weeks. Each follow-up will last for 20 minutes. Follow-up communications will include: (1) general well-being assessments using brief, non-intrusive inquiries (e.g., How have participants felt overall in the past week/two weeks?); (2) disease management monitoring through standardized question tracking significant changes in their underlying diseases, intentionally avoiding exploration of intervention-targeted lifestyle behaviors (e.g., Have participants experienced notable changes in their health status or disease management approach since last contact?); and (3) addressing disease-related inquiries. For any questions inquired by participants in the control group, general advice will be given for ethical consideration."
