Promoting Physical Activity in People Who Have a Long-Standing Spinal Cord Injury

The main objective of the study described in this thesis was to examine the effectiveness of a 16-week self-management intervention –called HABITS- in changing the level of physical activity of people who have lived with a spinal cord injury for a long time. We also examined whether the self-management intervention contributed to an improvement in the level of exercise behaviour of the participants and whether it resulted in an improvement in their self-management skills. We have performed a randomized controlled trial. This study showed no diffences between the intervention (HABITS) and the control group. In addition, the study tested the validity of a newly developed device for appropriately measuring the physical activity of the participants; this was based on an activity monitor that measured their self-propelled wheelchair driving. This study showed high validity results.
The main research of this thesis was based on a theoretical model of the relationship between self-management skills and physical activity. This model was based on two behavioural change theories: the transtheoretical model of behavioural change and the theory of planned behaviour. A further aspect of the study, therefore, was to investigate the relationship between self-efficacy and physical activity, testing the hypothesis that, among people with a long-standing spinal cord injury, those who have a higher level of self-efficacy level have higher activity levels. We have confirmed this hypotheses.
