Hi. I am conducting an experiment and I would like to understand if people would be willing to share a 4-seat vehicle with people they do not know. I have thought that the personal tendency of trusting other people might be an important factor. What kind of construct would you suggest to measure this? Would you have any suggestions in terms of other factors that might influence willingness to share a vehicle for a (short, e.g. 10-15 mins or less) journey?
I am also considering the BFI-10 construct to measure personality, but I would like to include another factor. Thanks!
