Culturally Appropriate Strategies for Chinese Americans With Diabetes (CASCADe)

The CASCADe program includes 1) a home visit for training of monitoring devices use, WeChat app and acquiring family support, 2) 8 weekly education sessions with a combined format of group class, games, food demonstration, group exercise, video and discussion, 3) WeChat follow-up on education tips, monitoring data summary, and group discussion. The monitoring system used a smartphone to coordinate cloud data transmission from a set of wireless devices to capture daily monitoring data on physical activity, body weight, blood pressure and blood glucose levels. WeChat app was used to facilitate behavioral self-monitoring by providing daily messages related to diabetes education curriculum, weekly summary reports on monitoring data as well as reinforcement messages and group discussion on readings and monitoring results implication. A single group pre-post-test design was adopted to evaluate changes of primary (HbA1c) and secondary (Self-efficacy, quality of life and stress coping) outcomes assessed at pre and post of intervention. Engagement and adherence in education sessions and self-monitoring system, and satisfaction with the content and delivery of intervention were also evaluated at the end of the study.
