I am currently doing my master's dissertation on the effects of flight shame on the choice of eco-labelled flights in a discrete choice experiment.
However, I am looking for a suitable and validated scales to measure the constructs shame and guilt. I am aware of proneness scales such as the TOSCA-A scale , but am unsure whether or not proneness scales would be suitable for my research as I am trying to figure out if they experience any shame or guilt while selecting their flights during the choice experiment.
Many thanks.
