I am going to do a quasi-experimental cross sectional study that measures the effect of new broadcasts on the fear of death compared to psychological distance. The idea is to divide the participants into two groups of equal size. One group sees a montage of news items including: the Ukraine crisis, a Boko Haram attack and an oil crisis in Brazil. The second group gets the same video but instead of the Boko Haram item it will show an item about the recent Paris terrorist attacks. I am not sure how to effectively measure death anxiety in this case because I want to have a before and after the video result so we can see what effect the videos have on the fear of death. Could anyone help me out?
