The purpose of this study is to evaluate the effectiveness of a 3-month control-theory-based online support intervention consisting of 8 online video teleconsultations and access to a secure online personal health record on self-management behaviours of adults with type 2 diabetes, as measured by the Summary of Diabetes Self-Care Activities (SDSCA). Secondary outcomes will include glycemic control, BMI, waist circumference, diabetes self-efficacy, computer and health literacy, patient satisfaction with care and perceived ease of use and perceived usefulness of the technology.
