Brief summary

The overall purpose of the final study is to undertake a randomised control trial to test the efficacy of an internet delivered physical activity intervention for individuals with Type II diabetes. The randomised control trial will consist of two groups, an intervention and control group. As previously described the intervention group will receive access to all aspects of the internet intervention, whereas, the control group will only be able to access a static web page containing links to external diabetes websites. Specifically, the following hypothesis will be tested: Hypothesis One: It is hypothesised that participants in both groups will report increases in physical activity behaviour, quality of life, physical activity intentions, subjective norms, attitudes and perceived behavioural control at 12 weeks; a) It is hypothesised that participants in the intervention group will report significantly greater improvements in physical activity behaviour than the control group; b) It is hypothesised that participants in the intervention group will report significantly greater improvements in their perception of quality of life than the control group; c) It is hypothesised that participants in the intervention group will report significantly greater improvements in physical activity intentions, subjective norms, attitudes and perceived behavioural control than the control group; Hypothesis Two: It is hypothesised that individuals in the intervention group will record significantly greater logins in comparison to the control group at the completion of the intervention period. The combined outcome will provide a better understanding of the effectiveness of internet delivered physical activity behaviour change programs for secondary prevention of chronic diseases. Secondary aims are to explore factors within internet delivered programs which influence website usage in terms of engagement.

Interventions

The intervention group will be enrolled in a 12-week online physical activity intervention. The interventions website is developed based on a theoretical framework (Theory of planned behaviour) and self-management principles. Participants are asked to regularly visit the intervention website over the 12 week period, however the number of times they access the website and the amount of time they spend on the website is left entirely to their own discretion. During this 12 weeks through the websit

The intervention group will be enrolled in a 12-week online physical activity intervention. The interventions website is developed based on a theoretical framework (Theory of planned behaviour) and self-management principles. Participants are asked to regularly visit the intervention website over the 12 week period, however the number of times they access the website and the amount of time they spend on the website is left entirely to their own discretion. During this 12 weeks through the website participants will be able to access weekly education modules, view a library of resources, be able to self-monitor behaviours (view graphs and progress) and participate in discussion forums. In relation to self-monitoring behaviour's participants and will be asked to record self-care behaviours such as physical activity, blood glucose and blood pressure daily and weight weekly. Additionally, participants can set weekly physical activity goals for which they will receive feedback based on their physical activity progress. However, although participants are encouraged through weekly email reminder to make use of all areas of the website, the areas accessed and the utilisation of these tools is left up to the participants discretion.
