**7. Limitations and future research**

This research has limitations common to a conceptual study, a future study therefore may extend the body of knowledge by empirically testing the survey, which may contribute additional insights to this study.

About methodological issues, there is a clear need to test the survey scales. While coherency and further development of existing scales is a good starting point, particular attention needs to be paid to ensuring that the scales are indeed applicable in a decision context. To this end, in-depth interviews with decision makers should help generate an appropriate pool of survey scales with a high level of content validity. Subsequently, rigorous psychometric analysis should be undertaken to assess the dimensionality, reliability, and validity of the derived scales, using survey data from a large sample of decision makers. It is also particularly important to establish convergent and discriminant validity among the dimensions.
