Explicit motivation will be assessed using self-report questionnaires. Explicit attitudes using a 7-point bipolar response scale, participants will be asked to indicate for each of the 4 pairs of positive and negative adjectives used how much they associate them with regular PA and sedentary behaviors, respectively. Perceived behavioral control using a 7-point bipolar response scale, patients will be asked to indicate how well they felt they were able to engage in regular PA, and limit their sedentary behaviors, respectively, based on two items. Intentions using a 7-point bipolar response scale, patients will be asked to indicate how much they intend to adopt regular physical activity, and limit their sedentary behaviors, respectively, according to two items. Fears and beliefs related to physical activity and work will be measured by the FABQ in its French version

Implicit attitudes will be assessed by administering an Implicit Association Test on physical and sedentary activities. Sitting in front of a computer, participants will see a series of words appear in the middle of the screen referring to 4 conceptual categories - located at the top of the screen. Two represent the targeted behaviours (here, physical activity versus sedentary lifestyle) while the remaining two represent attributes (here, positive versus negative adjectives). The adjectives used will be the same as those used to measure explicit attitudes. The instructions given to the participant are to classify the words as quickly as possible, according to the semantic category to which they belong
