The promising benefits of the Interactive Behavior Change Technology (IBCT) on diabetes patient self-management are increasingly recognized. In this paper, we describe development of a knowledge portal prototype designed for enhancing self-management support among patients with type-2 diabetes. The portal focuses on personalization of the provided services: self-regulation, self-monitoring and evaluation, social support, virtual home visit and reminder. One of the development challenges is in designing a core framework that coordinates the related data, knowledge, interactions and personalized services in facilitating patients’ self-care.

INTRODUCTION Diabetes is a worldwide burden; its prevalence is expected to rise to 366 million by 2030 [1]. Diabetes patients’ daily lives are generally known to have a great impact on the patients’ health. It is advocated that diabetes must be principally managed by the patient on a day-to-day basis such as dietary habits (e.g., size and timing of meals, carbohydrate and saturated fat intake), increase in exercise (e.g. walking), intake of medications (correct dosage and timing as well as consistency over time), and monitoring of blood sugar levels, blood pressure, blood lipids, feet, and eyes. Unfortunately, self-management support occurs inconsistently during outpatient visits [2]. Effective diabetes self-management support requires a complex series of assessments and instructions. As a result, patients often require additional support and communication outside of the traditional clinician visit [2]. Further, the information provided for patients received should take into account each patient’s distinctive life circumstances. Thus, providing services aimed at achieving health-related behavior change is challenging and often requires the time, knowledge and skills.
