I have methodological questions related to my research. I have one dependent variable which is vicarious embarrassment. The vicarious embarrassment variable is influenced by participant empathy. However, the quality of participant empathy is influenced by gender differences, ownership of the relationship with the protagonist (someone who commits an embarrassing act) which is divided into two categories namely (a) related and (b) stranger. In addition, participant empathy is also influenced by attributions to the perpetrators and the embarrassing event which consists of 4 orthogonal categories: (a) AA, (b) AU, (c) IA, and (d) IU. I ask for enlightenment related to the method that I can do, whether between- subject or within-subject. Thank you very much for your explanation.
