Informed subscale
This subscale informs about the presence of conflict regarding the knowledge participants have around the benefits and risks of the options. The mean score for this subscale showed no conflict (mean = 20.83; SD = 19.71) and there were no significant differences between groups (Group 1 felt that their decision was mainly informed by the content of the health states (43%), the graphical representation of the risks and benefits of taking LMWH (43%), and their previous experience (29%). Some participants (29%) showed some conflict (> 25-<37.5) because they didn’t know if other options were available (like oral anticoagulants). In Group 2, all participants (100%) were aware of the options, and exclusively referred to the graphical representations to inform about the benefits and risks of each option. There was one outlier that showed a higher conflict (> 37.5) in comparison with the rest of the group; this participant reported not having enough information about the benefits of taking LMWH. Group 3 felt they knew the risks and benefits of each option due to: the information provided by the health states (50%); the graphical representations (38%), and previous experience (25%).
