The promotion of regular physical activity for people with type 2 diabetes poses a challenge for public health authorities. The purpose of this study was to evaluate the efficiency of a computer-tailoring print-based intervention to promote the adoption of regular physical activity among people with type 2 diabetes. An experimental design was used; 325 participants between the age of 35 and 55 years old were randomized in one of two experimental conditions: the computer-tailoring intervention and the generic intervention. The two dependant variables were the frequency of participation and the intention to participate in leisure-time physical activities. Among the research hypotheses, only one was confirmed: the first computer-tailoring print on the practice of physical activity was more efficient than the first generic intervention at 1-month follow-up. Other similar studies will be necessary to determine the real potential of this type of approach for people with type 2 diabetes in a real-life setting.
