Hi, following the choice of Rindfleisch et al. (2009), my survey will use the participants' education (1 = high school, 4= postgraduate degree) as a marker variable to detect common method bias. But in my survey education only includes 4 options, which is different from Rindfleisch et al. (2009) that has 6 items.
Is this still doable to test CMV? Thank you so much!
