Thesis (Ph.D.)--Chulalongkorn University, 2011

The purpose of this study was to develop the interactive muti-mutimodalities technology (IMM) including website, email, and SMS for self-management support and to evaluate the effects of IMM among patients with diabetes type 2 who lived in Bangkok after 3-month overtime. The 4 settings with 124 participants were subsequently allocated to the intervention group (n=74) and the control group (n=48). The IMM on the website consists of 4 main functions that were self-regulation, self-monitoring and assessment, social support, and reminder system-linked to email, SMS. After 3 months, the participants declined in both groups to 55 and 30 respectively. T-test, Chi-square test, and Multiple regression with correlation were used to examine means of HbAlc level and behavioral scores including diabetes quality of life (QoL), self-efficacy, and self-management. The findings revealed that were a significant difference in HbA1c between the intervention and the control group (p 0.001). HbA1c level decreased in the intervention group but it increased in the control group significantly (p < 0.01). Self-care score increased significantly between groups (p < 0.05 ) and within the intervention group (p < 0.001). The increasing self-efficacy score associated with decreasing HbAlc (p < 0.05). A further study will expand to a large population and deliver the technology to diabetes clinic. However, the IMM should be improved to be fully functionality. Importantly, the providing health professional should plan for the exclusive further system.
