Response to an Exercise Intervention for Patients with Type 2 Diabetes: A Preliminary Study of Processes of Change

Based on the transtheoretical model, this study aimed to examine if the variability of physical activity (PA) level between subjects with type 2 diabetes (T2D) exposed to the same exercise intervention could be explained by the number and type of processes of change (POC) used. Twenty-eight patients completed measures of POC and PA level at baseline and 3 months later at the issue of the intervention. The results suggested that patients, who increased their PA level after 3 months, raised their number of POC activated and used both types of POC contrary to participants whose PA level decreased. These preliminary results help to further understand the psychological processes involved in the variability of responses to an intervention among T2D patients.
