Evaluation of an online support program for Type 2 diabetes self-management and dysphoria (depression, anxiety, and diabetes-specific distress).

National randomised controlled trial of an automated, web-based program aimed to improve Type 2 diabetes self-management and dysphoria (depression, anxiety, and diabetes-specific distress) by primarily targeting physical activity, nutrition, health routines, and emotional well-being. Being a self-guided program, participants use the program at their own discretion. The Intervention group are sent an email reminder if they have not logged on in >/= 2 weeks. The prgoram has not set duration, as in, participants are free to access the program indefinitely, although the main trial period is 12 months (or, for participants who choose to be followed up in the future, 5 years). There are three treatment arms in this trial, which involve the (i) usual care, (ii) wait-list control, and (iii) intervention arms. Usual care receives access to limited components of the full program throughout the trial (information resources, quizzes, and the health routines program module). The wait-list control arm receives access only to information resources and brief quizzes for the initial 3 months of participation, and then receives full program access. The intervention arm receives access to the full OnTrack Diabetes program. This includes information resources and brief quizzes on diabetes self-care (as accessible by treatment arms i and ii); self-monitoring tools and automated feedback graphs for physical activity and nutrition goal progress, blood glucose levels (daily highest and lowest), and mood (daily best and worst); access to My Diary, which is an electronic diary; and signposts for physical activity, eating, health routines, emotional wellbeing, and keeping ontrack, which each contain interactive tools based on cognitive behavioural therapy techniques of goal-setting, planning, problem-solving, etc, as well as mindfulness and meditation resources.
