This approach offers valuable insights into whether and the extent to which certain conditions are necessary for the outcome of interest, which is different from the underlying sufficiency interpretations of regression and fuzzy set qualitative comparative analysis (QCA). With the growth of NCA applications across scientific domains (Dul, 2016a; Dul et al., forthcoming; Karwowski et al., 2016; Van der Valk, Sumo, Dul, & Schroeder, 2016; Vis & Dul, 2018), there is also potential for novel applications in tourism.

This research note presents information for scholars seeking to understand the potential applicability of NCA in tourism, as well as guidelines for appropriate application and interpretation of results. The note provides useful details …
