Physical activity: the importance of the extended theory of planned behavior, in type 2 diabetes patients

This study focused on the contribution of the extended theory of planned behavior regarding intention to perform physical activity, adherence to physical activity, and its mediator role in the relationship between trust in the physician and adherence to physical activity, in a sample of 120 patients with type 2 diabetes. The results revealed that positive attitudes and perception of control predicted a stronger intention to do physical activity. The intention to do physical activity was the only predictor of adherence to physical activity. Planning mediated the relationship between trust in the physician and adherence. Implications for patients with type 2 diabetes are discussed.
